Seth L. Eichenholtz

Seth L. Eichenholtz is an attorney with a practice focused on patent litigation, primarily representing plaintiffs. He serves as "of counsel" at Berkeley Law & Technology Group, an intellectual property firm that specializes in patent, trademark, copyright, trade secret law, and IP strategy. The firm's patent attorneys are noted for their expertise in building and enforcing patent portfolios.

Eichenholtz's case experience, where he has appeared as "of counsel," predominantly involves patent assertion on behalf of Express Mobile, Inc., a patent assertion entity focused on mobile and web application development tools. His engagements include representing Express Mobile, Inc. as plaintiff in cases such as EXPRESS MOBILE, INC. v. International Business Machines Corporation and EXPRESS MOBILE, INC. v. Home Depot U.S.A., Inc. These matters generally involve patents related to browser-based website generation tools, systems for integrating widgets on mobile devices, and web design technology.

The broader Express Mobile litigation, with which Eichenholtz has been associated, has seen significant activity, including appearances before the U.S. Court of Appeals for the Federal Circuit and proceedings before the Patent Trial and Appeal Board (PTAB). For instance, in Express Mobile, Inc. v. Meta Platforms, Inc., Express Mobile appealed a PTAB decision concerning the patentability of its browser-based web generation technology, leading to a Federal Circuit vacatur and remand of the Board's decision. Similarly, EXPRESS MOBILE, INC. v. GODADDY.COM, LLC involved IPR proceedings related to Express Mobile's patents. While other firms have been lead counsel on significant Express Mobile outcomes, such as a $40 million verdict against Shopify Inc. and a $170 million verdict against GoDaddy, these cases highlight the high-stakes nature of the patent disputes Eichenholtz has been involved with.
