REDWOOD CITY, Calif., Jan. 31, 2017 (GLOBE NEWSWIRE) -- Coherus BioSciences, Inc. (Nasdaq:CHRS), today announced that it has filed four petitions for Inter Partes Review (“IPR”) in the United States Patent and Trademark Office seeking invalidation of AbbVie’s U.S. Patent 9,085,619 (“ ‘619 patent”).  The ‘619 patent is generally directed to formulations of adalimumab that do not contain a buffer.

“The ability of proteins to self-buffer has been known for decades.  We believe these IPRs present strong legal rationales as to why the ‘619 patent should never have issued, and these independent legal arguments provide multiple challenges to the ‘619 patent for the Patent Office to consider,” said Denny Lanfear, President and Chief Executive Officer of Coherus, noting further “these IPRs are part of our multifaceted formulation development and legal strategy for CHS-1420, our Humira biosimilar candidate, which envisions various paths for advancing an adalimumab formulation to market.  We identified formulation IP early on as a key area of focus, and legal activity including earning patents and disputing patents in this area will likely continue.  We remain committed to launching CHS-1420 once approved.”
