Acquired Distinctiveness and Genericness Evidence Checklist: A Practical Checklist

In 2004 an online skin-care retailer owned by a dermatologist told the USPTO, in a verified statement, that its LOVELYSKIN mark had become distinctive through five years of substantially exclusive and continuous use. The lawyer who prepared the filing had not investigated whether the use was in fact exclusive, and the associate he handed it to could not later remember whether she had. Six years on, a competitor counterclaimed to cancel the registration, and the district court cancelled it after a bench trial. The owner got its registration back on appeal only because the challenger's proof turned out to be even thinner than the owner's file: Lovely Skin, Inc. v. Ishtar Skin Care Products, LLC, 745 F.3d 877 (8th Cir. 2014). Distinctiveness disputes are won and lost on files like that one. This checklist is the list of what belongs in the file, for the side that owns the mark and for the side attacking it.

The short answer

Every exhibit in a distinctiveness fight answers one question: what does the relevant public understand this word, design, or color to mean? The owner needs the answer to be "a brand, from one source," proved for the exact matter claimed and as of the date the forum cares about. The challenger needs the answer to be either "the name of the product" (genericness, which no evidence of brand recognition can cure) or "a description that has not yet become a brand" (no acquired distinctiveness).

For acquired distinctiveness, the evidence sorts into the six factors the Federal Circuit restated in Converse, Inc. v. International Trade Commission, 909 F.3d 1110 (Fed. Cir. 2018): association by actual purchasers (usually shown by surveys), length, degree, and exclusivity of use, amount and manner of advertising, sales and number of customers, intentional copying, and unsolicited media coverage. For genericness, it sorts into dictionaries, media and trade usage, competitor usage, the owner's own usage, and Teflon or Thermos surveys. The tasks that matter most are the unglamorous ones: frame the question and the date before collecting anything, aim each exhibit at the matter actually claimed, prefer quality (look-for advertising, independent declarations, a properly designed survey) over volume (raw advertising budgets and revenue), and get each exhibit into the record in the form the forum requires.

The doctrine behind each item is explained in Genericness, Genericide, and Acquired Distinctiveness: Where Trademark Protection Begins and Ends. The order of operations, from office action to trial, is in Proving Acquired Distinctiveness and Defeating a Genericness Challenge: A Practical Guide. Model declarations, survey specifications, and usage guidelines are in the Distinctiveness Toolkit: Secondary Meaning Declarations, Genericness Surveys, and Brand Usage Guidelines.

How to use this checklist

Phase 1 applies to everyone and comes first. After that, pick the phases that fit your posture. Items that begin with Owner are for the party claiming distinctiveness or defending a registration; items that begin with Challenger are for the examining attorney's adversary, the opposer, the petitioner, or the accused infringer. Unlabeled items apply to both sides, because each side should assemble the other side's best exhibits before the other side does.

Phase 1: Frame the question, the forum, and the date (both sides)

• Write down, in one sentence each, which questions are in play: is the matter merely descriptive, has it acquired distinctiveness, and is it generic? Note: The questions call for different evidence. Proof of acquired distinctiveness cures a refusal under 15 U.S.C. § 1052(e)(1) through 15 U.S.C. § 1052(f), but nothing cures genericness: a generic term is incapable of acquiring distinctiveness (H. Marvin Ginn Corp. v. International Ass'n of Fire Chiefs, Inc., 782 F.2d 987 (Fed. Cir. 1986)), and the USPTO treats a 2(f) claim for generic matter as legally insufficient however much evidence comes with it (TMEP § 1212.02(i)). When an examiner refuses on both grounds, brand-recognition evidence is useful against the genericness refusal only as proof that the term is not the name of the category.
• Identify the forum and the posture, and write down who bears the burden there. Note: In examination, the examining attorney must establish a reasonable evidentiary predicate for a genericness refusal (USPTO Examination Guide 1-22 reads the older "clear evidence" formulation that way), and the applicant always carries the 2(f) burden. Before the Board, the challenger proves genericness by a preponderance, and in an opposition the applicant keeps the ultimate burden on acquired distinctiveness (Yamaha International Corp. v. Hoshino Gakki Co., 840 F.2d 1572 (Fed. Cir. 1988)). In court, a Principal Register registration shifts the burden to the challenger under 15 U.S.C. § 1057(b) and 15 U.S.C. § 1115(a); an unregistered or Supplemental Register mark leaves it on the owner (Filipino Yellow Pages, Inc. v. Asian Journal Publications, Inc., 198 F.3d 1143 (9th Cir. 1999)), subject to the Second Circuit's rule that the defendant bears the burden when it claims the public expropriated a term the plaintiff coined (Murphy Door Bed Co. v. Interior Sleep Systems, Inc., 874 F.2d 95 (2d Cir. 1989)).
• Fix the relevant date and write it on the front of the file. Note: In litigation, secondary meaning must have existed before each accused infringer's first use, and a registration's presumption runs only from the registration date forward (Converse). In an opposition, acquired distinctiveness is judged on the record at decision (Coach Services, Inc. v. Triumph Learning LLC, 668 F.3d 1356 (Fed. Cir. 2012)). A timely petition to cancel a 2(f) registration asks whether the mark had acquired distinctiveness when it registered (Lovely Skin). Evidence from the wrong period is the most common reason a thick file proves nothing.
• Define the genus from the identification of goods or services, not from anyone's marketing. Note: The identification in the application or registration defines both the genus and the relevant public (Magic Wand, Inc. v. RDB, Inc., 940 F.2d 638 (Fed. Cir. 1991)). A term that names a key aspect or a subcategory of the identified goods is generic for them (In re Cordua Restaurants, Inc., 823 F.3d 594 (Fed. Cir. 2016); Royal Crown Co. v. Coca-Cola Co., 892 F.3d 1358 (Fed. Cir. 2018)). Owner: read the identification as a whole and list everything the term does not name. Challenger: test the key-aspect and subcategory framings before settling on the genus.
• Define the relevant public as the actual and potential purchasers of the identified goods, and write the definition down. Note: For business goods the public may be engineers or procurement staff, as in Nartron Corp. v. STMicroelectronics, Inc., 305 F.3d 397 (6th Cir. 2002), where the Sixth Circuit looked to participants in the semiconductor industry and held SMART POWER generic. The written definition later becomes the survey universe and the yardstick for every declaration, article, and web page in the file.
• Pin down exactly what is claimed: the whole mark, one element of a composite, a product design, packaging, a color, or a combination of elements. Note: Evidence must speak to the matter claimed. In In re Louisiana Fish Fry Products, Ltd., 797 F.3d 1332 (Fed. Cir. 2015), sales and advertising for LOUISIANA FISH FRY PRODUCTS said little about the highly descriptive phrase FISH FRY PRODUCTS, the only matter for which distinctiveness was claimed. For trade dress, write a precise list of elements now; a vague or shifting definition undermines every later exhibit.
• Place the matter honestly on the distinctiveness spectrum, and decide whether to argue inherent distinctiveness before claiming 2(f). Note: A 2(f) claim is treated as a concession that the matter is not inherently distinctive (TMEP § 1212.02(b)) unless it is made in the alternative (TMEP § 1212.02(c)). The burden of proving acquired distinctiveness rises with the degree of descriptiveness (In re Steelbuilding.com, 415 F.3d 1293 (Fed. Cir. 2005)), the Board must make an express finding on that degree before weighing the evidence (Royal Crown), and some laudatory phrases cannot function as marks on any record (In re Boston Beer Co., 198 F.3d 1370 (Fed. Cir. 1999)). See 2 McCarthy on Trademarks and Unfair Competition § 15:33 on the sliding scale.
• Check the registration's age and whether a Section 15 declaration has been filed. Note: Lack of acquired distinctiveness is a ground for cancellation only within five years of registration; after that, a petition is limited to genericness and the other grounds listed in 15 U.S.C. § 1064(3), and 15 U.S.C. § 1065(4) denies incontestable rights in a generic name. Once a registration is incontestable, the mark also cannot be attacked as merely descriptive in litigation (Park 'N Fly, Inc. v. Dollar Park & Fly, Inc., 469 U.S. 189 (1985)).
• Issue a preservation notice covering advertising archives, sales data, media files, customer correspondence, website history, and enforcement letters. Note: The owner's best exhibits are usually old and scattered across departments; the challenger's best exhibits are often the owner's own documents. For mechanics, see Litigation Hold and Evidence Preservation Checklist: A Practical Checklist.

Phase 2: Use history and exclusivity

• Owner: Document the first use date for each product line and territory with dated specimens, invoices, launch materials, and archived web pages. Note: First use dates in a declaration should match the application and any prior filings. Inconsistent dates are an easy cross-examination and can taint the rest of the testimony.
• Owner: Build a continuous-use timeline showing every change in how the mark or trade dress appeared: logo updates, packaging redesigns, reformulations, rebrands, and periods of reduced use. Note: Length of use counts only for the matter as claimed. A word used for decades in a different form, or a trade dress whose elements have drifted, earns less credit than the raw years suggest.
• Record how the mark has been displayed: prominence, use of ™ or ®, position relative to the house mark, and any use of the term in its ordinary descriptive sense. Note: What counts is use as a mark (TMEP § 1212.05). Prominent display with a trademark symbol makes sales and advertising figures more probative; a term printed under a dominant house mark, or used to describe the product ("our creamy formula"), makes them less so. Restatement (Third) of Unfair Competition § 13 makes the same point for litigation: what matters is how prospective purchasers encounter the designation.
• Run and document an exclusivity audit before anyone signs a statement of substantially exclusive use: USPTO and state registers, business-name filings, domain names, online marketplaces, app stores, social media handles, and industry directories. Note: "Substantially" exclusive tolerates inconsequential third-party use (TMEP § 1212.05(b); L.D. Kichler Co. v. Davoil, Inc., 192 F.3d 1349 (Fed. Cir. 1999)), but a claim with no exclusivity proof fails: five years of use without evidence of exclusivity did not establish secondary meaning in Art Attacks Ink, LLC v. MGA Entertainment Inc., 581 F.3d 1138 (9th Cir. 2009). Keep the search reports; Lovely Skin shows what happens when no one can say an investigation was done.
• For each third-party use found, record its extent, duration, geography, promotion, and status (ceased, licensed, challenged, or tolerated). Note: Challenger: a list of registrations or business names is not proof of third-party use. In Lovely Skin the Eighth Circuit held that registrations and business names, without evidence of how or whether they were used, promoted, or recognized during the five years before registration, could not rebut the presumption attached to a 2(f) registration. Investigate actual use, with dates.
• Owner: Collect license agreements and quality-control records for every licensee, distributor, or related company that uses the mark. Note: Use by a related company benefits the owner under 15 U.S.C. § 1055 only when the owner controls the nature and quality of the goods. Uncontrolled licensing undercuts exclusivity and source significance at the same time. See Trademark Licensing and Quality Control: How Naked Licensing Kills a Brand.
• Owner: Decide whether the five-year statement can carry the claim alone, and assume it cannot for anything more than mildly descriptive. Note: The statement is prima facie evidence only "in appropriate cases," and "further evidence may be required" (37 C.F.R. § 2.41(a)(2)). The Office may refuse to accept it for a highly descriptive term (Louisiana Fish Fry), and it is usually insufficient for product designs, colors, and highly descriptive matter (TMEP § 1212.05(a)). The statement is verified under 37 C.F.R. § 2.20, whose declaration language warns that willful false statements are punishable under 18 U.S.C. § 1001 and may jeopardize any resulting registration.
• Owner: Inventory active Principal Register registrations of the same mark for sufficiently similar goods. Note: Ownership of a prior registration may be prima facie evidence under 37 C.F.R. § 2.41(a)(1), but only if the new mark is the legal equivalent of the registered one (In re Dial-A-Mattress Operating Corp., 240 F.3d 1341 (Fed. Cir. 2001)) and the goods are closely enough related (TMEP § 1212.04). Supplemental Register registrations do not qualify, and a prior registration that is itself vulnerable is a weak foundation.

Phase 3: Advertising and promotion

• Owner: Assemble advertising spend by year, broken out by campaign and medium, and isolate the spend on materials that actually display the claimed matter. Note: Totals that include house-brand campaigns, trade show travel, and general overhead invite a discount. So do ads that never show the claimed feature: in First Brands Corp. v. Fred Meyer, Inc., 809 F.2d 1378 (9th Cir. 1987), the Ninth Circuit held that advertising supports secondary meaning in trade dress only if it features the dress itself, and noted that the antifreeze maker had never urged buyers to look for its "familiar yellow jug."
• Owner: Pull dated samples of look-for advertising and of any advertising that calls attention to the claimed matter. Note: Advertising must direct the consumer to the features claimed (Yankee Candle Co. v. Bridgewater Candle Co., 259 F.3d 25 (1st Cir. 2001)). Explicit "look for" language is the gold standard, as in the "think pink" campaigns in In re Owens-Corning Fiberglas Corp., 774 F.2d 1116 (Fed. Cir. 1985), but it is not mandatory: the Seventh Circuit held that ads prominently featuring the oval head of a cable tie could also draw buyers' attention to the shape (Thomas & Betts Corp. v. Panduit Corp., 138 F.3d 277 (7th Cir. 1998)).
• Record reach for each campaign: impressions, circulation, ratings, web visits, and social engagement, by period and audience. Note: The Trademark Rules ask for advertising expenditures "identifying types of media and attaching typical advertisements" (37 C.F.R. § 2.41(a)(3)), not bare totals. Spending measures effort; reach to the relevant public is closer to effect.
• Flag every ad, package panel, help page, app store listing, and social post that uses the term as a noun, a verb, or a description. Note: These are the challenger's exhibits. In In re Gould Paper Corp., 834 F.2d 1017 (Fed. Cir. 1987), the applicant's own materials were the strongest evidence that SCREENWIPE named the product. Owner: fix them now and keep a record of the fix. Challenger: request the full archive, including drafts, style guides, and agency briefs.
• For trade dress and color, separate ads that isolate or emphasize the feature from ads that merely picture the product. Note: In Forney Industries, Inc. v. Daco of Missouri, Inc., 835 F.3d 1238 (10th Cir. 2016), a quarter century of in-store displays and more than half a billion dollars in sales did not show secondary meaning in packaging colors, because nothing in the promotion called attention to the colors as a source signal.
• Challenger: Ask the owner's marketing witness whether any campaign told consumers to look for the claimed matter, and for the creative briefs that set each campaign's message. Note: A clear "no" from a corporate designee under Fed. R. Civ. P. 30(b)(6) can neutralize years of spending figures.

Phase 4: Sales and market position

• Owner: Compile unit and dollar sales under the mark by year, region, and channel, from the system of record. Note: Present multi-year data as a summary chart, with the underlying records produced, under Fed. R. Evid. 1006.
• Owner: Put the numbers in context: market share and rank, number of customers, repeat purchase rates, and growth that tracks branding campaigns. Note: Raw revenue proves that people like the product, not that they read the term as a brand. A hit telephone on the market for about eighteen months pointed "strongly away" from secondary meaning in Cicena Ltd. v. Columbia Telecommunications Group, 900 F.2d 1546 (Fed. Cir. 1990), and roughly $85 million in annual sales could not rescue a laudatory phrase in Boston Beer.
• Owner: Identify sales in which the claimed matter was the only branding the buyer saw, such as unlabeled product photos, shelf tags, or search results that show only the term. Note: Those sales speak to the claimed matter; sales under a prominent house mark speak mostly to the house mark.
• Challenger: Attribute the sales to other causes: the house mark, price, distribution, product utility, first-mover advantage, or a period of patent exclusivity. Note: Association that exists only because one seller was the only seller does not make a generic name protectable. After the shredded wheat patents expired, the public's association of the product with its original maker gave that maker no exclusive right in the name or the pillow shape (Kellogg Co. v. National Biscuit Co., 305 U.S. 111 (1938)).

Phase 5: Unsolicited media and third-party recognition

• Owner: Collect articles, reviews, awards, books, and widely seen social posts that refer to the term or design as the owner's, each with its date and audience size. Note: Considerable unsolicited coverage of the Stan Smith sneaker's iconic status supported secondary meaning in its trade dress in adidas America, Inc. v. Skechers USA, Inc., 890 F.3d 747 (9th Cir. 2018).
• Separate earned media from press releases, paid placements, sponsored posts, and paid influencer content. Note: Paid content proves promotion, not perception. Label the difference in the exhibit list rather than letting cross-examination find it.
• Record how each publication styles the term: capitalized, followed by "brand," paired with a generic name, or used as a lower-case noun for the category. Note: The same clippings can cut both ways. In In re Merrill Lynch, Pierce, Fenner & Smith, Inc., 828 F.2d 1567 (Fed. Cir. 1987), press usage the Board read as generic showed, on closer reading, substantial recognition of CASH MANAGEMENT ACCOUNT as Merrill Lynch's, and the refusal was reversed.
• Owner: Keep a running unsolicited-media file with screenshots, URLs, and capture dates, updated at least quarterly. Note: For capture and authentication practice, see Capturing the Web: A Practitioner's Guide to Authenticating Website Screenshots as Evidence in Federal Court.

Phase 6: Copying and actual confusion

• Gather knockoffs, "-style" and "-type" listings, keyword bids on the term, lookalike packaging, and listings that borrow the owner's photographs or copy, each with a capture date. Note: Listings that call a product "[MARK]-style" are double-edged. They suggest the copier saw source value in the name, but they can also become evidence that the trade uses the mark as a style name, the argument that made the "Tiffany setting" a jury question in Tiffany & Co. v. Costco Wholesale Corp., 971 F.3d 74 (2d Cir. 2020).
• Look for evidence of why the copier copied: instructions to manufacturers, design briefs, emails, and listing histories. Note: The circuits divide on what copying proves. The Ninth Circuit requires no separate intent to confuse; deliberate copying of nonfunctional features "supports a strong inference of secondary meaning," as when a competitor had its factory build exact copies of a rival's furniture from photographs (Jason Scott Collection, Inc. v. Trendily Furniture, LLC, 68 F.4th 1203 (9th Cir. 2023); P & P Imports LLC v. Johnson Enterprises, LLC, 46 F.4th 953 (9th Cir. 2022)). The Seventh Circuit treats copying as evidence only if the copier meant to confuse buyers and pass off its goods (Thomas & Betts Corp. v. Panduit Corp., 65 F.3d 654 (7th Cir. 1995)), and the Tenth Circuit has held that, for product design, copying plus strong sales did not create a triable issue because designs are usually copied for their utility or appeal (Craft Smith, LLC v. EC Design, LLC, 969 F.3d 1092 (10th Cir. 2020)). Know your circuit before you build the case on a knockoff.
• Challenger: Document legitimate reasons for any copying: utility, aesthetic appeal, compatibility, industry convention, or an expired patent. Note: Competitors who copied an appealing product were trying to sell an appealing product, not trade on goodwill (Cicena). A party claiming trade dress in a feature claimed by an expired utility patent carries a heavy burden of showing that the feature is not functional (TrafFix Devices, Inc. v. Marketing Displays, Inc., 532 U.S. 23 (2001)).
• Log every instance of actual confusion (misdirected orders, inquiries, reviews, returns) with its date and the confused person's relationship to each party. Note: Some courts treat actual confusion as evidence of secondary meaning, but scattered instances carry little weight, and confusion among people who know the owner personally carries almost none (Japan Telecom, Inc. v. Japan Telecom America Inc., 287 F.3d 866 (9th Cir. 2002); Art Attacks).

Phase 7: Purchaser and trade declarations

• Owner: Choose declarants from the relevant public defined in Phase 1: independent customers, end users, and professional buyers, not employees, distributors, relatives, or friends. Note: Statements from people with a stake in the outcome, or a personal tie to the owner, are routinely discounted (Filipino Yellow Pages; Japan Telecom; Art Attacks).
• Owner: Have each declarant explain, in his or her own words, how they encountered the term or design and what it signifies to them. Never circulate a form. Note: In In re Hotels.com, L.P., 573 F.3d 1300 (Fed. Cir. 2009), the Board gave no weight to sixty-four identical form declarations stating that HOTELS.COM is not a generic name, because they explained nothing, and the Federal Circuit affirmed the genericness finding. See TMEP § 1212.06(c).
• Owner: Aim for enough declarants, from enough places and channels, to look like the market. Note: Testimony from one or a few purchasers rarely carries the issue; the Ninth Circuit called testimony from a single source insufficient in Art Attacks.
• Use the right attestation for the forum. Note: At the USPTO and the Board, use the declaration language of 37 C.F.R. § 2.20. In federal court, use the unsworn declaration form of 28 U.S.C. § 1746. Board testimony may be submitted by declaration, subject to the adverse party's right to cross-examine the witness (37 C.F.R. § 2.123(a)(1)).
• Use trade statements (retailers, distributors, industry associations) where the trade is part of the purchasing public, and say so in the declaration. Note: The Trademark Rules contemplate "letters or statements from the trade or public" (37 C.F.R. § 2.41(a)(3)). Where the buyers are consumers, statements from the trade about what consumers think are weak secondhand evidence.
• Challenger: Depose a sample of declarants about how they were recruited, who drafted the statement, what they would call the product, and whether they know any other source. Note: A declarant who calls the product by the claimed term and cannot name a second word for it is a genericness witness.

Phase 8: Surveys

• Decide whether a survey is needed, and record the reasons either way. Note: No rule requires one; Coach Services and Yamaha both sustained 2(f) showings without a survey. But surveys are direct evidence of perception, which the Federal Circuit called preferable to indirect evidence in Princeton Vanguard, LLC v. Frito-Lay North America, Inc., 786 F.3d 960 (Fed. Cir. 2015), and for highly descriptive terms, product designs, colors, and contested litigation the absence of a survey is a gap the other side will argue.
• Retain an independent survey expert through counsel with a written engagement that defines the question; counsel never designs or fields the survey. Note: The Ninth Circuit approved excluding two surveys designed by the plaintiff's lawyer in Elliott v. Google, Inc., 860 F.3d 1151 (9th Cir. 2017). In federal court, drafts and most attorney-expert communications are protected under Fed. R. Civ. P. 26(b)(4), but facts, data, and assumptions counsel supplied are discoverable, and the report must satisfy Rule 26(a)(2)(B).
• Match the format to the question, and avoid formats built for other questions. Note: Teflon (brand or common name) comes from E.I. DuPont de Nemours & Co. v. Yoshida International, Inc., 393 F. Supp. 502 (E.D.N.Y. 1975); Thermos (what do you call it) from American Thermos Products Co. v. Aladdin Industries, Inc., 207 F. Supp. 9 (D. Conn. 1962). Secondary meaning calls for an association survey with a control. The Eveready confusion format, named for Union Carbide Corp. v. Ever-Ready Inc., 531 F.2d 366 (7th Cir. 1976), is sometimes offered for secondary meaning too, but a Squirt-style lineup survey that primes respondents was held not probative of secondary meaning in Parks LLC v. Tyson Foods, Inc., 863 F.3d 220 (3d Cir. 2017).
• Define the universe as the relevant public from Phase 1, and screen for it. Note: The Seventh Circuit called a survey of 13- to 18-year-old girls "worthless" because they were an arbitrary subset of the consumers of beanbag stuffed animals (Ty Inc. v. Softbelly's, Inc., 353 F.3d 528 (7th Cir. 2003)).
• Build a control, report net figures, and strip other branding from the stimulus. Note: Respondents need not name the source; association with a single, even anonymous, source is enough (Tone Brothers, Inc. v. Sysco Corp., 28 F.3d 1192 (Fed. Cir. 1994)). A survey that biases respondents and does not control for guessing earns little weight (First Brands).
• Time the fieldwork to the relevant date, and be ready to explain any gap. Note: Royal Crown questioned the weight of a survey taken years before the decision; Converse adds that surveys conducted within five years of the relevant date may provide evidence of secondary meaning, and that uses older than five years count only if they likely shaped perception as of that date.
• Read results against case benchmarks. Note: For secondary meaning, majority association is strong evidence; figures in the thirties are marginal but still probative and go to the fact finder with everything else (Thomas & Betts, 138 F.3d 277); 23 and 28 percent helped only alongside strong circumstantial proof (Zatarains, Inc. v. Oak Grove Smokehouse, Inc., 698 F.2d 786 (5th Cir. 1983)); about ten percent cut against the claim (Real Foods Pty Ltd. v. Frito-Lay North America, Inc., 906 F.3d 965 (Fed. Cir. 2018)). For genericness, Teflon brand percentages in the sixties and above are strong evidence for the owner.
• Run a pilot, then preserve the questionnaire, screener data, stimuli, verbatim answers, coding protocol, and validation records. Note: Admissibility runs through Fed. R. Evid. 702, which since 2023 requires the proponent to show reliability by a preponderance. Skewed questions cost the HOTELS.COM survey most of its weight (Hotels.com).
• Never substitute an internet poll, website vote, or social media survey. Note: An online poll that did not count participants or prevent repeat voting "does not even remotely follow the precepts" of proper surveys (Steelbuilding.com).
• Recognize when a survey cannot help. Note: A survey will not rescue a term that dictionaries, competitors, and the trade already use as a category name. The Fourth Circuit held a survey irrelevant to "crab house" because the plaintiff had not coined the term (Hunt Masters, Inc. v. Landry's Seafood Restaurant, Inc., 240 F.3d 251 (4th Cir. 2001)), and the Board said much the same about Teflon surveys for ordinary terms in Frito-Lay North America, Inc. v. Princeton Vanguard, LLC, Opp. No. 91195552 (T.T.A.B. Sept. 6, 2017).
• Challenger: Audit the owner's survey line by line (universe, screener, stimulus, control, question order, coding, timing), and commission a rebuttal survey only if a competent expert expects a materially different result. Note: For design standards, see Trademark Consumer Survey Design: A Practical Checklist and Consumer Survey Expert Methodology in Trademark Cases: A Practical Guide; for the exclusion fight, Daubert Challenges to Consumer Survey Experts in Trademark Litigation: A Practical Guide; for deposing the expert, the Expert Deposition Preparation Checklist: A Practical Checklist.

Phase 9: The genericness record (challenger builds, owner audits)

• Collect dictionary entries (general, specialized, and online), recording the edition or access date, and note whether each entry flags the term as a trademark. Note: A lower-case entry that defines the term as the name of the product is strong evidence for the challenger; an entry that labels the term a trademark helps the owner. Tribunals may take judicial notice of dictionary definitions under Fed. R. Evid. 201, but dictionaries are only one source, and a missing entry proves little either way (Nartron).
• Collect media and trade-publication usage, weighting publications that the relevant public actually reads. Note: The record in Surgicenters of America, Inc. v. Medical Dental Surgeries Co., 601 F.2d 1011 (9th Cir. 1979) included magazine and medical journal articles using "surgicenter" for the category, and the Ninth Circuit affirmed that the coined combination of "surgery" and "center" was itself generic.
• Collect competitor usage: trade names, product names, listings, packaging, and category pages. Note: Competitor usage is often decisive. Competitors' use of "brick oven" for a style of frozen pizza supported genericness in Schwan's IP, LLC v. Kraft Pizza Co., 460 F.3d 971 (8th Cir. 2006), and tour operators across the country using "duck tour" in their names led the First Circuit to hold the phrase generic and vacate an injunction in Boston Duck Tours, LP v. Super Duck Tours, LLC, 531 F.3d 1 (1st Cir. 2008).
• Collect the owner's own generic usage, including usage by employees, partners, and agencies. Note: In America Online, Inc. v. AT&T Corp., 243 F.3d 812 (4th Cir. 2001), AOL's own employees used "IM" as a noun and a verb despite management's admonitions, and the Fourth Circuit affirmed the refusal to enforce "IM" and "You Have Mail" while sending "Buddy List" to trial. Company policy does not erase company practice.
• Collect public usage online (reviews, forums, social posts, search suggestions), and code each use as brand-conscious or indiscriminate. Note: Verb use is evidence, not the test. A person who says "I googled it" may mean "I used Google," which is brand use (Elliott). Coding by an independent reviewer, with a written protocol, keeps the exercise from becoming advocacy.
• Trace the term's history before the owner adopted it. Note: A company cannot take a word out of the language that already named the category, even a slang word: "hog" was generic for large motorcycles before Harley-Davidson made trademark use of it (Harley-Davidson, Inc. v. Grottanelli, 164 F.3d 806 (2d Cir. 1999)). Dictionary definitions of "freebie" as slang for something given without charge helped defeat FREEBIES for periodicals about free mail-order offers, even though the mark had been registered on a five-year statement (Retail Services, Inc. v. Freebies Publishing, 364 F.3d 535 (4th Cir. 2004)), and CHOCOLATE FUDGE was generic for a chocolate-fudge-flavored diet soda (A.J. Canfield Co. v. Honickman, 808 F.2d 291 (3d Cir. 1986)).
• Check misspellings, abbreviations, initialisms, and phonetic equivalents of generic words. Note: Because "light" was generic for a type of beer, neither that word nor its phonetic equivalent LITE could be appropriated as a mark for beer (Miller Brewing Co. v. G. Heileman Brewing Co., 561 F.2d 75 (7th Cir. 1977)). An initialism for a generic phrase stands in the same place (America Online, on "IM").
• Check meanings in other languages spoken by the relevant public. Note: Under the doctrine of foreign equivalents, a word that is generic in another language may be generic here; the Second Circuit vacated an injunction because the trial court refused to consider what "otokoyama" means in Japan (Otokoyama Co. v. Wine of Japan Import, Inc., 175 F.3d 266 (2d Cir. 1999)).
• Check patents, technical standards, plant variety filings, and model designations that use the term as the name of the thing. Note: A varietal name for a plant is the generic designation of that variety (In re Pennington Seed, Inc., 466 F.3d 1053 (Fed. Cir. 2006)). A term used as the product's name in its own patents is in a similar position, as "shredded wheat" was in Kellogg.
• Pull the USPTO file history: the owner's disclaimers, arguments, and declarations, prior refusals of the term, and third-party registrations that disclaim it. Note: A disclaimer under 15 U.S.C. § 1056 concedes that matter is unregistrable alone. In a cancellation, the entire registration file, including evidence submitted during prosecution, is automatically of record (Cold War Museum, Inc. v. Cold War Air Museum, Inc., 586 F.3d 1352 (Fed. Cir. 2009)), so the owner's prosecution statements come in for both sides.
• Ask whether the public has another efficient name for the product, and document what it is. Note: Bayer lost ASPIRIN with consumers because they knew no other word for the drug (Bayer Co. v. United Drug Co., 272 F. 505 (S.D.N.Y. 1921)); Google kept GOOGLE in part because "search engine" was available and no competitor needed "google" to name its own product (Elliott). In the Second Circuit, though, an available alternative does not save a word the public already uses as the name of the product (King-Seeley).
• For compound terms and domain names, gather evidence about the meaning of the whole term, not only its parts. Note: Dissecting a compound and declaring each part generic is error (In re American Fertility Society, 188 F.3d 1341 (Fed. Cir. 1999); Princeton Vanguard). After USPTO v. Booking.com B.V., 591 U.S. 549 (2020), there is no per se rule that "generic.com" is generic; the answer turns on consumer perception, which is why pre-2020 decisions such as In re 1800Mattress.com IP, LLC, 586 F.3d 1359 (Fed. Cir. 2009) now matter for their evidence, not their outcomes.
• Challenger: Before registration, consider a letter of protest that puts dictionary, media, and competitor evidence in front of the examining attorney. Note: It is inexpensive and early; see Expungement, Reexamination, and Letters of Protest: The Trademark Modernization Act in Practice.
• Challenger: Consider a Thermos-format survey with follow-up questions that separate respondents who name the product from those who name a favorite brand. Note: Without the follow-ups, a dominant brand's market share can masquerade as genericness, and the owner's expert will say so.

Phase 10: The owner's genericness defense file

• Adopt written brand usage guidelines and train marketing, sales, support, product, and agency staff on them. Note: A mark is abandoned when "any course of conduct of the owner, including acts of omission as well as commission," causes it to become generic (15 U.S.C. § 1127). Guidelines, training records, and enforcement of them are the owner's proof that its own conduct pointed the other way. A model set is in the Distinctiveness Toolkit.
• Pair the mark with a generic descriptor everywhere, and make sure the market has that descriptor available. Note: The descriptor gives the public, the press, and competitors a word other than the mark. The Seventh and Ninth Circuits give real weight to whether such a word exists: the Seventh Circuit has said genericide does not typically occur until competitors cannot compete effectively without using the mark (Ty), and the Ninth Circuit relied on the fact that no competitor called its search engine "a google" (Elliott). The Second Circuit held instead that the test is what the public understands the word to mean, whatever alternatives exist (King-Seeley Thermos Co. v. Aladdin Industries, Inc., 321 F.2d 577 (2d Cir. 1963)). Either way, the descriptor works only from the start: the thermos maker spent its first sixteen years popularizing "Thermos bottle" without the generic terms then in use, and by the time it paired the mark with "vacuum bottle," the public already said "thermos."
• Keep a policing log of corrections sent to publishers, dictionaries, competitors, marketplaces, and app stores, with each response and outcome. Note: In Elliott the Ninth Circuit treated Google's policing of dictionary publishers as evidence against genericide, citing Filipino Yellow Pages and King-Seeley for the converse point that a failure to police supports genericness.
• Commission a baseline Teflon survey from an independent expert and repeat it at intervals that match the brand's risk. Note: A stable brand percentage over years is powerful evidence; Google's Teflon survey showed more than ninety percent brand responses (Elliott). A baseline taken before any dispute also looks less like litigation advocacy.
• Collect brand-conscious public and press usage: capitalized references, "brand" usage, and articles that identify the owner as the source. Note: Mixed usage resolves in the owner's favor more often than owners expect, because the test is primary significance, not exclusive significance (Merrill Lynch).
• Map the presumptions and burdens before choosing a forum or a theory. Note: A registration is prima facie evidence of validity, and the presumption attached to a 2(f) registration includes acquired distinctiveness (Cold War Museum). Circuits differ on what the presumption does in court: Converse joined the majority view that it shifts both the burden of production and the burden of persuasion, while the Fourth Circuit treats it as shifting only the burden of production, so strong genericness evidence makes it drop out (Retail Services).
• Identify which goods in the registration are most exposed, and decide whether a narrower identification is safer than defending the whole. Note: Genericness can be found as to "a portion" of the goods (§ 1064(3)), and the Board may restrict a registration under 15 U.S.C. § 1068, as a court may under 15 U.S.C. § 1119. Losing the core goods to defend peripheral ones is a bad trade.

Phase 11: Product designs, packaging, colors, and other nontraditional matter

• Classify the matter as product design or packaging, and treat close cases as design. Note: Product design is never inherently distinctive and always needs secondary meaning (Wal-Mart Stores, Inc. v. Samara Bros., 529 U.S. 205 (2000)); packaging and décor can be inherently distinctive (Two Pesos, Inc. v. Taco Cabana, Inc., 505 U.S. 763 (1992)). See TMEP § 1202.02(b).
• For packaging that uses color, consider arguing inherent distinctiveness first, and check the forum's rule. Note: The Federal Circuit held that color marks on product packaging can be inherently distinctive, depending on the character of the color design, and rejected the Board's rule that multicolor marks never can be (In re Forney Industries, Inc., 955 F.3d 940 (Fed. Cir. 2020)). The Tenth Circuit, in the same company's earlier lawsuit, required colors to be combined with a well-defined shape, pattern, or design before packaging color could be inherently distinctive (Forney, 835 F.3d 1238).
• Build the functionality record before the distinctiveness record. Note: Acquired distinctiveness cannot cure functionality (15 U.S.C. § 1052(e)(5)). Gather the evidence the examiner will ask about under In re Morton-Norwich Products, Inc., 671 F.2d 1332 (C.C.P.A. 1982): utility patents, advertising that touts utilitarian advantages, available alternative designs, and comparative manufacturing cost. A feature is functional if it is essential to the use or purpose of the article or affects its cost or quality (Inwood Laboratories, Inc. v. Ives Laboratories, Inc., 456 U.S. 844 (1982); TrafFix). The owner of unregistered trade dress must prove nonfunctionality under 15 U.S.C. § 1125(a)(3).
• Owner: Remove utilitarian claims about the claimed feature from current marketing, and catalog the historical ones so they do not surprise you. Note: A catalog line saying the curve "supports the back" will be quoted back as an admission that the curve is functional.
• Show that the design is not a common form in the industry, or, for the challenger, that it is. Note: Where an industry customarily packages products a certain way, trade dress in that style is likely generic: black rectangular compacts in Mana Products, Inc. v. Columbia Cosmetics Manufacturing, Inc., 65 F.3d 1063 (2d Cir. 1995); grape leaves on wine labels in Kendall-Jackson Winery, Ltd. v. E. & J. Gallo Winery, 150 F.3d 1042 (9th Cir. 1998). A generic product design can be cancelled at any time, even from an incontestable registration (Sunrise Jewelry Manufacturing Corp. v. Fred S.A., 175 F.3d 1322 (Fed. Cir. 1999)).
• For a single color, gather advertising built around the color and evidence that the color serves no utilitarian or competitive purpose. Note: A color can be a mark only with secondary meaning (Qualitex Co. v. Jacobson Products Co., 514 U.S. 159 (1995); TMEP § 1202.05). Protection may be confined to the context in which the color acquired meaning: the Second Circuit limited Louboutin's red-sole mark to red outsoles that contrast with the upper (Christian Louboutin S.A. v. Yves Saint Laurent America Holding, Inc., 696 F.3d 206 (2d Cir. 2012)).
• In any survey, show unbranded stimuli of the claimed design and use a control that removes or alters the claimed feature. Note: The control separates association with the claimed feature from association with the product category or with features that are not claimed. Respondents need not name the source (Tone Brothers).
• Plan on actual evidence rather than a five-year statement. Note: The TMEP warns that five years of use will usually not suffice for product designs and colors (TMEP § 1212.05(a)), and the trade dress materials in the Trade Dress Protection Toolkit: From Product Design and Packaging to Registration, Functionality, and Enforcement assume a full evidentiary showing.

Phase 12: Getting the evidence into the record

At the USPTO

• Put every piece of evidence in before any appeal. Note: The record should be complete before the notice of appeal; new evidence afterward requires a request to suspend and remand (37 C.F.R. § 2.142(d)). An ex parte appeal under 15 U.S.C. § 1070 is decided on the examination record.
• Calendar the response deadline and any extension. Note: The response period is three months, extendable once by three months for a fee (37 C.F.R. § 2.62(a)). For the response itself, see Responding to a Trademark Office Action Checklist: A Practical Checklist.
• Choose and word the 2(f) claim deliberately: prior registration, five years of use, actual evidence, in part, or in the alternative. Note: Claim language templates are in the Distinctiveness Toolkit. A claim "in part" (TMEP § 1212.02(f)) or a disclaimer may be the better fit for a composite mark.
• Keep the Supplemental Register in reserve, and know its conditions. Note: Registration under 15 U.S.C. § 1091 requires lawful use in commerce, so an intent-to-use applicant must first file an acceptable allegation of use, and the amendment resets the effective filing date (37 C.F.R. § 2.75(b)). Supplemental registration is not an admission that the mark lacks distinctiveness (15 U.S.C. § 1095). See Common-Law Rights, the Supplemental Register, and the Principal Register: A Practical Guide.
• Assume every word filed will be read by a future adversary. Note: The prosecution file is automatically part of a later cancellation record (Cold War Museum). Arguments that the term "describes" the goods, made to win a different point, become the challenger's exhibits.

Before the Board

• Introduce printed publications and internet materials by notice of reliance, including the URL and the access date for each web page. Note: 37 C.F.R. § 2.122(e). A web page admitted this way shows what it says and how a term was used, not the truth of its contents.
• Present witness testimony by declaration where it helps, and prepare each declarant for cross-examination. Note: Testimony declarations are permitted under 37 C.F.R. § 2.123(a)(1), and the adverse party may elect oral cross-examination. Use documents the witness can actually authenticate; Coach Services turned partly on marketing documents the sponsoring witness could not.
• Use discovery to collect the other side's usage and survey materials. Note: Board discovery follows the Federal Rules as modified by the Trademark Rules; interrogatories, document requests, and requests for admission under Fed. R. Civ. P. 36 about specific usages are efficient. See TTAB Discovery: A Practical Checklist.

In federal court

• Disclose witnesses, documents, and experts on time, and supplement. Note: Evidence produced late can be excluded under Fed. R. Civ. P. 37(c)(1); in Elliott, examples of supposedly generic verb use that had not been disclosed in discovery were excluded. See Rule 37(c)(1) Preclusion of Undisclosed Evidence: A Practical Guide.
• Authenticate web captures, ads, and media through a witness with knowledge or by certification. Note: Fed. R. Evid. 901 covers testimony and distinctive characteristics; certified business records and certain electronic records can be self-authenticating under Fed. R. Evid. 902(11), (13), and (14). See Authenticating Website Evidence: A Practical Checklist.
• Plan the hearsay route for each category. Note: Sales and advertising records usually come in as business records under Fed. R. Evid. 803(6); survey responses are generally admitted as evidence of respondents' state of mind under Rule 803(3) or because they are not offered for their truth; the expert may rely on facts of a kind experts reasonably rely on under Fed. R. Evid. 703.
• Build the summary judgment record early. Note: Genericness and secondary meaning are questions of fact, but courts resolve them under Fed. R. Civ. P. 56 when the record is one-sided, for owners (Elliott) and for accused infringers (Filipino Yellow Pages; Retail Services). See Summary Judgment Motion Checklist: A Practical Checklist.

Phase 13: Keep the file alive (owner)

• File the Section 15 declaration as soon as the registration has five years of continuous post-registration use, alongside the Section 8 declaration under 15 U.S.C. § 1058. Note: After incontestability, descriptiveness challenges are gone (Park 'N Fly); genericness challenges are not. See Maintaining Trademark Registrations.
• Refresh the evidence file every year: new ads with dates and reach, sales by mark, the media file, the policing log, and the copying log. Note: The owner who can produce a decade of organized evidence in a week controls the pace of any dispute.
• Repeat the exclusivity audit before every new 2(f) filing or five-year statement. Note: A statement that was true five years ago may not be true today.
• Do not assume secondary meaning travels to new goods. Note: A prior registration supports a new 2(f) claim only for sufficiently similar goods (TMEP § 1212.04), and a new product line needs its own evidence.
• Audit new channels where generic usage starts: marketplace listing templates, app store category pages, partner integrations, help-center articles, and automated product descriptions. Note: Generic use increasingly begins in text the owner did not write but could have controlled through contracts and platform settings. See the Online Trademark Enforcement Toolkit: Platform Notices, Test Purchase Records, and Contributory Liability Demands for platform notice practice.

Red flags that should change your plan

• The only advertising evidence is a budget. Without dated samples that show the claimed matter, the figure measures effort, not meaning. Find look-for material or rethink the 2(f) claim.
• Nobody can explain how "substantially exclusive" was verified. Stop and run the audit before signing anything (Phase 2).
• The owner's help center, packaging, or app listing uses the mark as a noun or verb. Fix it, document the fix, and assume the old versions will be exhibits.
• The survey universe is "U.S. adults." For anything but the broadest consumer goods, that is the wrong universe.
• Counsel drafted the declarations, and they all read the same. Expect them to be given no weight (Hotels.com).
• The claimed trade dress has no written element list, or the list keeps changing. Settle it before collecting evidence.
• Competitors already use the term to name their own products. Genericness is now the main risk, and a survey may not help (Hunt Masters; Schwan's).
• The evidence is dated after the relevant date. In litigation, recalculate around each defendant's first use (Converse).
• The challenger's case rests on registrations and business-name filings alone. Without proof of actual use, it will not rebut a registration's presumption (Lovely Skin).

Frequently asked questions

Who should sign the 2(f) declaration, and what if it later proves wrong? A verified statement must be signed by someone with legal authority to bind the owner, someone with firsthand knowledge and authority to act, or an attorney with a power of attorney (37 C.F.R. § 2.193(e)(1)). Choose the person who can testify to the facts, because the Board or a court may later ask that person to. A false statement can support cancellation for fraud only if it was a knowing, material misrepresentation made with intent to deceive the USPTO (In re Bose Corp., 580 F.3d 1240 (Fed. Cir. 2009)), but an honest mistake can still cost the registration if the underlying claim was untrue, and 15 U.S.C. § 1120 creates civil liability for registrations procured by false or fraudulent declarations.

Can secondary meaning for one product support a 2(f) claim for a new product? Sometimes. A prior registration supports the claim only for sufficiently similar goods (TMEP § 1212.04). An intent-to-use applicant normally cannot claim acquired distinctiveness before alleging use, because the claim presupposes use, but the USPTO recognizes a limited exception where the applicant shows that distinctiveness already established for the same mark on closely related goods will transfer to the new goods (TMEP § 1212.09(a); In re Rogers, 53 U.S.P.Q.2d 1741 (T.T.A.B. 1999)).

How many customer declarations are enough? There is no number. A few dozen thoughtful declarations from independent purchasers in different places and channels will do more than hundreds of identical forms, and declarations rarely carry a highly descriptive term without other evidence.

Do internal brand-tracking studies count? They can. The TMEP lists market research and consumer reaction studies alongside litigation surveys (TMEP § 1212.06(d)), and studies prepared in the ordinary course look less like advocacy. Check what they measured: awareness of the house brand is not association with the claimed term or design, and the full methodology will be discoverable once you rely on them.

What should a challenger do when the owner's survey is strong? Attack its relevance before its numbers: the genus, the universe, the stimulus, the timing, and whether the term was ever coined (Hunt Masters). Then ask whether genericness is the right fight at all. If the real point is that the client uses words in their ordinary sense, the descriptive fair use defense may be cheaper and safer; see Asserting or Defeating a Trademark Fair Use Defense: A Practical Guide.

Our product name is turning into a verb. What should we collect now? Start the Phase 10 file: adopt usage guidelines, settle on a generic descriptor, open a policing log, fix your own materials, and commission a baseline Teflon survey from an independent expert. Elliott shows that verb use alone does not kill a mark; the owners who lose are the ones who cannot show they fought the drift.

Practical takeaways

• Decide the question, the forum, the burden, the relevant date, the genus, and the relevant public before collecting a single exhibit.
• Aim every exhibit at the matter actually claimed, at the date that matters.
• Look-for advertising, independent declarations, and a well-designed survey beat large budgets, big revenue, and form statements.
• Document the exclusivity investigation behind every five-year statement.
• For genericness, competitor usage and the owner's own usage usually decide the case; build or audit those files first.
• For designs and colors, prove nonfunctionality first, write down the elements, and expect to need actual evidence.
• Put each exhibit into the record in the form the forum requires, on time.
