An opinion letter is formal legal analysis you can rely on and, when needed, point to. We write opinions on infringement, validity, freedom to operate, and patentability that do more than sit in a file: they back a product launch, answer an investor or lender, satisfy an insurer, and help establish the good-faith reliance that can negate willful infringement. Each one is a genuine exercise of judgment, not protective paperwork, because only a real opinion does any of that work.
Non-Infringement Opinions
We analyze whether your product, service, or feature infringes specific patents, trademarks, or copyrights. On patents that means construing the claims and comparing them to your design element by element. On trademarks we work through the likelihood-of-confusion factors; on copyrights we assess substantial similarity and fair use. The conclusion has to be both well-reasoned enough to rely on and clear enough to act on, so you know whether to ship, redesign, or negotiate.
Invalidity Opinions
When someone asserts a patent or other right against you, we analyze whether it would actually hold up. For patents we dig into prior art, claim scope, and prosecution history, and weigh anticipation, obviousness, enablement, written description, and indefiniteness. For trademarks we look at abandonment, genericness, fraud, and priority. A solid invalidity opinion gives you leverage, whether the next move is a design change, a license negotiation, or a fight.
Freedom To Operate And Patentability
A freedom-to-operate opinion surveys the whole relevant patent landscape before a launch or major technology decision, not just one or two known patents, using systematic searching and analysis of what turns up. A patentability opinion runs the other direction: before you spend on prosecution, we test novelty and non-obviousness against the prior art, gauge achievable claim scope, and tell you whether the filing is worth the investment.
Methodology And Privilege
An opinion is only as reliable as the work behind it. We build on thorough fact investigation and legal research, address the unfavorable factors as squarely as the favorable ones, and state our qualifications honestly so the reasoning holds up. Because opinions carry sensitive analysis, we protect attorney-client privilege and work product from the outset, advise you before any disclosure, and update opinions as new patents issue, claims get construed, or your product changes.
