Patent Litigation in South Carolina
An educational explainer on how patent cases resolve in South Carolina courts — the deadlines, the venue rules, and the strategy you can war-game as a simulation.
Where this case gets filed
The Court of Common Pleas is South Carolina's trial court of general civil jurisdiction, organized across 16 judicial circuits covering the state's 46 counties, and it hears contract, tort, and other civil disputes above the small claims threshold. Filings are made in the county circuit court tied to the defendant or the underlying dispute.
Venue is generally proper in the county where the defendant resides at the time the action is commenced, or, for corporate defendants, a county where the corporation does business.
South Carolina statutes of limitations
- Written contract: 3 years
- Oral contract: 3 years
- Personal injury: 3 years
- Fraud: 3 years, generally from discovery
- Property damage: 3 years
- Professional malpractice: Generally 3 years, with a separate statute of repose for medical malpractice — confirm current statute
Governing rules: South Carolina 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 South Carolina apportions fault and damages
South Carolina follows modified comparative negligence with a 51% bar, so a plaintiff found more at fault than the defendant cannot recover. Punitive damages are generally capped at the greater of three times compensatory damages or $500,000, with statutory exceptions for particularly egregious conduct such as intoxication or intentional harm.
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 South Carolina?
- It depends on the specific claim, but South Carolina's general limitations periods are: written contract claims — 3 years; fraud claims — 3 years, generally from discovery. Every case has its own facts and possible tolling exceptions, so confirm the exact deadline against the current South Carolina Rules of Civil Procedure before relying on it.
