Winston Secures Federal Circuit Affirmance of 101 Victory for Polycom
Winston secured an appellate victory for Polycom (now part of HP) when the Federal Circuit affirmed a judgment on the pleadings of patent-ineligibility in a lawsuit brought by directPacket Research, Inc. Working closely with HP, Winston argued that all claims of the asserted patent were directed to the abstract idea of translation via an intermediate protocol, with no inventive concept. The Northern District of California agreed, and the Federal Circuit unanimously affirmed, adopting Winston’s arguments. Eimeric Reig argued the appeal, working with HP and the Winston team, including Kathi Vidal, Kelly Hunsaker, Sam Lerner, Matt McCullough, and David Dalke.

Winston Secures Federal Circuit Victory for Snap Axing Image-Presentation Patents on the Pleadings
Ask Sydney sued Snap along with four large tech companies in the Western District of Texas, Waco Division, asserting infringement of two related patents on methods of generating and presenting images to a user to determine the user’s interest. Working closely with Snap, Winston successfully moved to transfer the case to the Central District of California, then moved for judgment on the pleadings of patent-ineligibility under § 101 of the Patent Act. Following a hearing with multiple rounds of argument, the district court granted the motion, adopting Winston’s arguments that distinguished findings by the patent examiner during prosecution and by the Western District of Texas, which had denied § 101 motions brought by two other defendants. Ask Sydney appealed, but the Federal Circuit summarily affirmed three days after oral argument, handing Snap a decisive win invalidating all claims of both asserted patents. Eimeric Reig led the strategy and argued the appeal and motion hearing, working with Kathi Vidal and Kelly Hunsaker.

What Is the Foreign Corrupt Practices Act (FCPA)?
The Foreign Corrupt Practices Act (FCPA) is a federal statute prohibiting United States citizens and entities from engaging in corruption. It has two main elements: (1) anti-bribery provisions, forbidding the giving or offering of anything of value to a foreign government official for business and (2) accounting requirements, establishing mandatory practice guidelines for companies to maintain accurate records and internal controls. The FCPA is enforced by the Department of Justice (DOJ) and the Securities and Exchange Commission (SEC).
