Eleanor M. Yost litigates high-stakes intellectual property disputes in state and federal courts, the U.S. International Trade Commission (ITC) and the United States Patent and Trademark Office (USPTO). She also manages national and international patent and trademark portfolios for some of the most recognizable brands in the world. Ms. Yost’s clients rely on her for a broad range of intellectual property and government contracts matters, including patent and trademark prosecution, opinions, licensing, due diligence, and transactions.

Ms. Yost, an in-demand thought leader on the subject of USPTO Patent Trial and Appeal Board (PTAB) post-grant proceedings, has been featured on the topic in IPLaw360, AmLaw Daily, Corporate Counsel, Inside Counsel, The Recorder, Intellectual Property Magazine, Bloomberg BNA, Reuters’ IP Westlaw Journal, The Pink Sheet, Managing IP, Lawdragon, and elsewhere. She launched the PTAB practice at an AmLaw 50 firm and was selected to be a founding member of the PTAB Bar Association Board of Directors, the leading national bar association for PTAB practitioners, judges, and other stakeholders. She is the lead author of PTAB Post Grant Proceedings: A Tactical Guide for Practitioners, and represents patent owners and petitioners in reexamination, inter partes review (IPR), post grant review (PGR) and covered business method review (CBMR) proceedings, and related appeals to the Federal Circuit.

In addition to her intellectual property practice, Ms. Yost assists clients navigating government contracts and procurement issues, particularly those involving the Federal Acquisition Regulations (FARs), Defense Federal Acquisition Regulations Supplement (DFARS) and the Bayh-Dole Act, among others. She counsels clients with respect to prime awards, grants (e.g., DARPA), subcontract arrangements, contract interpretation, performance, bid protests, and potential claims.
