S. Calvin Capshaw

S. Calvin Capshaw is a founding partner of Capshaw DeRieux, LLP, where his practice includes a significant focus on patent infringement litigation. He has spent his career in Texas, frequently representing clients in the U.S. District Court for the Eastern District of Texas. His work primarily involves asserting patent rights on behalf of plaintiffs against technology companies. The subject matter of these cases spans various technologies, including telecommunications, wireless content delivery, and consumer electronics.

Based on available case data, Mr. Capshaw's practice is weighted towards representing patent holders. The tracked case, Lepton Computing LLC v. Samsung, involves allegations that Samsung's foldable smartphones infringe upon Lepton's patents. News reports characterize the plaintiff, Lepton Computing, as a non-practicing entity (NPE). Public records show Mr. Capshaw has also served as local counsel for other patent assertion entities, such as SimpleAir Inc. in cases against Google and Microsoft, and Bluebonnet Telecommunications LLC in suits against various smartphone makers.

Mr. Capshaw has been a partner at his current firm, Capshaw DeRieux, LLP, since 2008. His prior experience includes working as a partner at Brown McCarroll, LLP, and as a briefing attorney for the Honorable William M. Steger in the Eastern District of Texas. There is no readily available information to suggest a regular practice before the Patent Trial and Appeal Board (PTAB).

Admitted to the State Bar of Texas in 1986, Mr. Capshaw earned his Juris Doctor from Baylor University School of Law the same year. He is also admitted to practice before several federal courts, including the U.S. Court of Appeals for the Federal Circuit.
