Christopher Lee Limbacher

Christopher Lee Limbacher is a patent litigator at Heim, Payne & Chorush, LLP, focusing on complex technology disputes. With a background as a software engineer in the healthcare and oil & gas industries, his practice primarily involves computer technologies and electrical engineering issues. The firm itself boasts extensive experience across a wide array of technical areas, including telecommunications, energy, computer architecture, microprocessors, and software development.

Limbacher demonstrates experience representing both patent owners and accused infringers. His plaintiff-side work includes representing Wapp Tech Limited Partnership and Wapp Tech Corp. in patent infringement litigation against financial institutions like Bank of America Corporation, concerning software tools for developing and testing mobile applications. This campaign by Wapp Tech previously yielded a significant jury verdict of $172.5 million, later settling for $67.5 million, on related patents. On the defendant side, he represented Wapp Tech Corp. as the patent owner in an inter partes review (IPR) proceeding initiated by Capital One, N.A.

His PTAB experience is notable, including successfully convincing the Patent Trial and Appeal Board to deny institution of an IPR challenging a Wapp Tech patent (U.S. Patent No. 8,924,192) by establishing an earlier priority date. Limbacher regularly handles IPR proceedings and ex parte patent reexaminations, reflecting the firm's active practice before the Patent Trial and Appeal Board.

He earned his J.D., summa cum laude, from the University of Houston Law Center, and holds a B.S. in Computer Science, with honors, from the Georgia Institute of Technology.
