Jason A. Wietjes

Jason A. Wietjes is a patent litigation attorney with Polsinelli, where he serves as a Shareholder in the firm's Intellectual Property & Technology Litigation Group. His practice focuses on representing both plaintiffs and defendants in complex intellectual property disputes, spanning a wide range of technologies. These include pharmaceuticals, software applications, hardware devices, business methods, cellular and computer networks, GPS systems, RFID systems, oil field and downhole tools, animal health products, chemical compounds, and microarrays. His background includes prior work as a Research Assistant in biopharmaceuticals, specifically in the development and manufacturing of vaccines and biotherapeutics.

While the tracked case data shows one appearance as lead counsel for a plaintiff, "ONE-E-WAY, INC. v. GN Audio USA, Inc.", his broader practice demonstrates experience representing clients on both sides of patent disputes. For example, he has represented generic pharmaceutical manufacturers as defendants in Paragraph IV Hatch-Waxman litigation, and defended clients against patent infringement claims related to RFID and online banking software. He has also acted for plaintiffs in inventorship and infringement cases.

Notable case work includes his involvement as lead counsel for One-E-Way, Inc., a matter that reached the U.S. Court of Appeals for the Federal Circuit in One-E-Way, Inc. v. International Trade Commission (2017). In this case, the Federal Circuit reversed an International Trade Commission ruling that One-E-Way's patents, directed to wireless digital audio systems for private listening with headphones, were invalid for indefiniteness, thereby reviving the patent claims. Wietjes also has experience in Patent Trial and Appeal Board (PTAB) proceedings, having been designated as backup counsel for patent owners in Inter Partes Review (IPR) matters.

Mr. Wietjes is admitted to the Texas bar and to practice before the United States Patent and Trademark Office. He holds a J.D. from the University of Nebraska-Lincoln College of Law (2003) and a B.S. in Biochemistry from the University of Nebraska (2000). He is also admitted to practice before the U.S. Court of Appeals for the Federal Circuit and several U.S. District Courts in Texas.
