Patent Litigation in Texas
An educational explainer on how patent cases resolve in Texas courts — the deadlines, the venue rules, and the strategy you can war-game as a simulation.
Where this case gets filed
Texas civil litigation of significant value is generally filed in District Court, the state's primary trial court of general jurisdiction, organized by county and often further divided into specialized civil, family, or business dockets in larger counties. Lower-value disputes may instead proceed in County Court at Law, and very small claims are handled in Justice Court. Which court is proper depends largely on the amount in controversy and the county's local court structure.
General venue rules place a suit in the county where the defendant resides, where a substantial part of the events giving rise to the claim occurred, or, for property disputes, where the property is located.
Texas statutes of limitations
- Written contract: 4 years
- Oral contract: 4 years
- Personal injury: 2 years
- Fraud: 4 years
- Property damage: 2 years
- Professional malpractice: Generally 2 years, with special notice and repose rules for medical malpractice — confirm current statute
Governing rules: Texas Rules of Civil Procedure.
What the two sides are actually fighting over
Patent Infringement
- Ownership or standing to assert a valid, enforceable patent
- The accused product or process practices every limitation of an asserted claim (literally or under the doctrine of equivalents)
- The acts of making, using, selling, offering to sell, or importing the invention
- Damages adequate to compensate, no less than a reasonable royalty
Invalidity Defense / Counterclaim
- The claimed invention was anticipated by a single prior-art reference, or
- Was obvious in light of the prior art to a person of ordinary skill, or
- The specification fails written description, enablement, or definiteness
- Proven by clear and convincing evidence to overcome the presumption of validity
How Texas apportions fault and damages
Texas follows modified comparative fault (termed proportionate responsibility), barring recovery once a plaintiff's share of responsibility reaches 51%. Exemplary (punitive) damages are generally capped at the greater of $200,000 or two times economic damages plus up to $750,000 in noneconomic damages, with exceptions for certain intentional torts and felony conduct.
The Markman ruling is the true settlement trigger: because construction so often resolves infringement and validity together, cases cluster their bargaining around it. The clear-and-convincing standard for invalidity gives patent owners a defensive edge, while the availability of a faster, lower-standard PTAB challenge gives accused infringers a counterweight and a stay lever. Enhanced-damages and fee-shifting exposure for willfulness or exceptional cases sharpens the tail risk on both seats, so parties negotiate against skewed outcome distributions rather than a clean midpoint.
How this area is war-gamed
- Treat claim construction as the master dial -- shifting a term's scope propagates simultaneously into infringement and validity element satisfaction.
- Model the PTAB inter partes review as a parallel branch with its own standard and clock, and simulate the stay decision as a strategic fork.
- Encode the clear-and-convincing invalidity bar versus the preponderance infringement bar as distinct burden thresholds each seat plays against.
- Turn the willfulness and enhanced-damages dials to read how tail risk reshapes the settlement window before and after Markman.
- What is the statute of limitations for a patent claim in Texas?
- It depends on the specific claim, but Texas's general limitations periods are: written contract claims — 4 years; fraud claims — 4 years. Every case has its own facts and possible tolling exceptions, so confirm the exact deadline against the current Texas Rules of Civil Procedure before relying on it.
- Which court hears a patent litigation case in Texas?
- Texas civil litigation of significant value is generally filed in District Court, the state's primary trial court of general jurisdiction, organized by county and often further divided into specialized civil, family, or business dockets in larger counties. Lower-value disputes may instead proceed in County Court at Law, and very small claims are handled in Justice Court. Which court is proper depends largely on the amount in controversy and the county's local court structure.
- Does Texas cap damages or use comparative negligence?
- Texas follows modified comparative fault (termed proportionate responsibility), barring recovery once a plaintiff's share of responsibility reaches 51%. Exemplary (punitive) damages are generally capped at the greater of $200,000 or two times economic damages plus up to $750,000 in noneconomic damages, with exceptions for certain intentional torts and felony conduct.
