Patent Litigation in Connecticut
An educational explainer on how patent cases resolve in Connecticut courts — the deadlines, the venue rules, and the strategy you can war-game as a simulation.
Where this case gets filed
Connecticut's trial court of general jurisdiction is the Superior Court, which handles essentially all civil litigation statewide since the state abolished separate municipal and county courts decades ago; it is organized into judicial districts rather than counties. Civil cases are filed at the judicial district courthouse that has venue over the matter, with a Small Claims docket handling lower-value disputes within the same Superior Court system.
Venue is generally proper in the judicial district where at least one defendant resides or, for corporate defendants, where they have a usual place of business. Some claims allow venue where the transaction or injury occurred.
Connecticut statutes of limitations
- Written contract: 6 years
- Oral contract: 3 years
- Personal injury: 2 years
- Fraud: 3 years from the act, subject to a discovery-based extension in some cases
- Property damage: 3 years
- Professional malpractice: Generally 2-3 years depending on the profession — confirm current statute
Governing rules: Connecticut Practice Book (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 Connecticut apportions fault and damages
Connecticut follows modified comparative negligence with a 50% bar, so a plaintiff whose fault is greater than the combined fault of the defendants recovers nothing, while lesser fault reduces the award proportionally. Connecticut does not generally allow punitive damages beyond litigation expenses (attorney's fees and costs) in most common-law tort claims, a notably conservative approach compared to many states — confirm treatment for the specific claim type.
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 Connecticut?
- It depends on the specific claim, but Connecticut's general limitations periods are: written contract claims — 6 years; fraud claims — 3 years from the act, subject to a discovery-based extension in some cases. Every case has its own facts and possible tolling exceptions, so confirm the exact deadline against the current Connecticut Practice Book (Rules of Civil Procedure) before relying on it.
- Which court hears a patent litigation case in Connecticut?
- Connecticut's trial court of general jurisdiction is the Superior Court, which handles essentially all civil litigation statewide since the state abolished separate municipal and county courts decades ago; it is organized into judicial districts rather than counties.

- Does Connecticut cap damages or use comparative negligence?
- Connecticut follows modified comparative negligence with a 50% bar, so a plaintiff whose fault is greater than the combined fault of the defendants recovers nothing, while lesser fault reduces the award proportionally. Connecticut does not generally allow punitive damages beyond litigation expenses (attorney's fees and costs) in most common-law tort claims, a notably conservative approach compared to many states — confirm treatment for the specific claim type.
