Samsung Electronics Co., Ltd. v. Elm 3DS Innovations, LLC

Elm owns the Challenged Patents, which share a specification and all relate to “stacked integrated circuit memory.” The Challenged Patents are the subject of co-pending litigation between Elm and Petitioners. The Patent Trial and Appeal Board instituted inter partes review and held that Petitioners did not establish the unpatentability of 105 claims across 11 patents. The Federal Circuit affirmed. Each challenged claim requires a low-tensile-stress dielectric, and substantial evidence supports the Board’s finding that a person of ordinary skill in the art would not have reasonably expected success in combining the prior art to meet this limitation. The court construed the term “substantially flexible” as largely able to bend without breaking and contains a circuit layer that is substantially flexible semiconductor substrate and a sufficiently low tensile stress dielectric material.
