Practice Area
The United States International Trade Commission (ITC) is an increasingly popular venue for patent infringement litigation. More and more companies are seeking to halt importations of infringing products into the United States by turning to the ITC for expedited relief. Section 337 investigations conducted by the ITC provide complainants with a “fast track” to remedy IP matters that typically go to trial within 10 months. Since many Section 337 cases go to trial, selecting an ITC litigation team with a command of the technology, patent law, and specialized procedural practice is extremely important. We have handled more than 100 cases before the ITC.

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.

Colloquially referred to as the “patent dance,” the BPCIA provides a framework that includes certain steps and a schedule during which the applicant and reference product sponsor exchange confidential information disclosed in the aBLA. During the patent dance, the applicant and sponsor identify the patents that could be litigated in the future during two potential phases of litigation. In the first phase, the sponsor can allege infringement of a subset of the patents identified during the patent dance. The second phase begins after the sponsor receives the Notice of Commercial Marketing from the applicant. During this second phase, the sponsor can assert any remaining patents that were not asserted in the first phase.
