On January 13, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision affirming the District Court’s judgment of invalidity as to the asserted claims of U.S. Patent No. 8,720,320 (the ‘320 patent) and the award of attorney’s fees. The CAFC also affirmed the ruling of infringement as to the asserted claims of U.S. Patent No. 8,707,855 (the ‘855 patent). Adrian Rivera and Adrian Rivera Maynez Enterprises, Inc. (ARM), owner of the ‘320 patent, initiated the lawsuit against Eko Brands LLC (Eko), owner of the ‘855 patent. ARM claimed Eko infringed claims 5-8 and 18-20 of the ‘320 patent.

On November 23, the Court of Appeals for the Federal Circuit (CAFC) reversed the Patent Trial and Appeal Board’s (PTAB) ruling in a pair of inter partes review (IPR), which had invalidated all claims of two related patents, U.S. Patent Nos. 9,014,243 and 8,718,158. TQ Delta, the patent owner, appealed the PTAB’s holding that all claims of the challenged patents would have been obvious when viewed in light of the prior art references, including U.S. Patent Nos. 6,144,696 (Shively) and 6,625,219 (Stopler), asserted by Cisco System Inc. and the other appellees (collectively, “Cisco”). Admissibility of evidence, claim construction, and due process were among several other challenges raised by TQ Delta on appeal. Because the PTAB’s determination of obviousness was not supported by substantial evidence, the CAFC reversed.
