  • Although the Patent Office remains open for the electronic and physical filing of patent documents and the payment of patent-related fees during the current COVID-19 national emergency, the U.S. Patent and Trademark Office (USPTO) is using authority granted to it under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) to offer a waiver of certain filing and fee payment deadlines associated with obtaining and maintaining patent applications and issued patents., CARES Act May Offer Short-term Relief for Patent Owners on Certain Filing and Fee Deadlines in April 2020, Intellectual Property
  • On Monday, August 12, 2019, the Federal Circuit issued a precedential opinion on means-plus-function claims.

  • On June 14, 2019, the Federal Circuit issued a precedential opinion holding that state sovereign immunity does not apply to Inter Partes Reviews (IPR). Regents of the Univ. of Minn. v. LSI Corp., 2019 U.S. App. LEXIS 17887 (Fed. Cir. 2019). The Federal Circuit’s decision focused on the differences between IPRs and lawsuits, likening the Patent Office proceedings to federal agency enforcement actions. Thus, state entities, including public colleges and universities, cannot rely on sovereign immunity to shield their patents from IPRs., Federal Circuit Opinion Holds That State Sovereign Immunity Doesn't Apply In IPRs, Intellectual Property
