Intellectual Property and TechnologyPatent Litigation

District court patent litigation is where most infringement fights are decided, and we handle these cases in federal courts nationwide from early assessment through claim construction, trial, and appeal, pairing real technical fluency with courtroom advocacy.

Federal district court is the main arena for patent infringement disputes, and the technology usually decides the case. We represent patent owners and accused infringers across the country, and because our attorneys were software engineers before they were litigators, we read the patents and the accused products ourselves instead of waiting for an expert to explain them. That fluency shapes everything from the theories we build to how we frame the technology for a judge and jury.

Choosing the Right Venue

Where a patent case is filed shapes how it plays out. We weigh judge experience, local patent rules, time to trial, jury pools, and procedural practices when picking a forum to assert claims, and we challenge improper venue when we're on defense. After TC Heartland tightened the rules, venue is a live battleground at the outset of a case, and getting it right early can set the tone for the entire dispute.

Building the Case

Strong patent cases are built early. We analyze the patents and the accused products, develop infringement and invalidity theories, identify the documents and witnesses that matter, and run an honest early case assessment so you make strategic calls with a clear view of strengths and exposure. That assessment drives the real decisions: how hard to push, where to invest, and whether the case belongs in trial or settlement.

Claim Construction and Discovery

The Markman hearing, where the court interprets the claims, often decides the case before trial. We develop constructions grounded in the intrinsic record and the technology, then argue them in a way that frames claim scope our client's way. Through fact and expert discovery, we manage document production efficiently, take and defend the depositions that build the record, and prepare the technical evidence, controlling cost while building proof that holds up.

Experts, Trial, and Appeal

Technical and damages experts can win or lose a patent case. We work with strong experts to develop infringement, validity, and damages opinions, prepare them to testify clearly, and challenge the other side's experts through Daubert motions. At trial, we make complex technology understandable and build a narrative the factfinder can follow. When the verdict is in, we carry the case through post-trial motions and appeal to the Federal Circuit.

Frequently asked questions

Federal district court patent cases generally take 2-3 years to reach trial, though it swings widely with the venue and the complexity of the case. Many cases settle well before trial.

Delaware, the Eastern and Western Districts of Texas, and the Northern District of California carry heavy patent dockets. Where a case lands affects the timeline, the local rules, and how the litigation plays out.

Claim construction is the court deciding what the disputed terms in the patent claims mean, usually at a Markman hearing. It often decides the case, because how a key term is defined can determine whether the accused product infringes or whether the patent is valid.

At a minimum you can recover a reasonable royalty, and lost profits if you can prove them. Willful infringement can lead to enhanced damages of up to three times the award, and injunctions are available in the right circumstances.

The main ones are non-infringement, invalidity based on prior art or other grounds, inequitable conduct, and patent exhaustion. Which defenses carry the most weight depends entirely on the facts of your case.

It is worth a hard look, because patent litigation is expensive. An early case assessment weighs the likely cost, the risks on the merits, and the business impact so you can decide whether settling beats fighting it out.
