The PTAB improperly found that the patent is unpatentable in view of the prior art.
Concluding that the Patent Trial and Appeal Board improperly construed certain claims in a patent for memory system circuits owned by Innovative Memory Systems, Inc. in an inter partes review filed by Micron Technology, Inc., the U.S. Court of Appeals for the Federal Circuit has reversed the Board’s finding of unpatentability. The Federal Circuit reversed the Board’s construction for the term “wherein the correspondence of blocks to zones is adjustable by controller” in the patent claims and the Board’s conclusion about a limitation in the patent claims based on prior art references (Innovative Memory Systems, Inc. v. Micron Technology, Inc., August 27, 2019, Prost, S.).
