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 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.

Served as lead trial counsel to defend AMD in a massive ITC action brought against AMD by its competitor Realtek Semiconductor Corp. Realtek accused AMD of infringing three patents relating to integrated circuit designs. AMD faced an exclusion order and a cease-and-desist order at the ITC. Administrative Law Judge (ALJ) Cameron Elliot’s decision found that all asserted claims of two of the patents were invalid for multiple reasons. For the third patent, he ruled that all asserted claims were not infringed by AMD, and that all but one of those claims were also invalid. ALJ Elliot also found that Realtek had not proven the existence of the economic prong of domestic industry—a rare outcome at the ITC. The win is significant for AMD because dozens of its product families were implicated. It also sends a signal to non-U.S. companies that the ITC’s domestic-industry requirement has teeth and cannot be assumed to exist based merely on a patentee’s alleged licenses with U.S.-based entities.

What Is Trademark Infringement?
Trademark infringement is defined as the unauthorized use of a trademark or service mark. This use can be in connection with goods or services and may lead to confusion, deception, or a misunderstanding about the actual company a product or service came from. Trademark owners can take legal action if they believe their marks are being infringed. If infringement of a trademark is proven, a court order can prevent a defendant from using the mark, and the owner may be awarded monetary relief.

What Is the Domestic Industry Requirement?
The domestic industry requirement for Section 337 investigations at the U.S. International Trade Commission (ITC) mandates that a complainant asserting patent infringement at the ITC, or complainant’s licensee, has made in the United States significant investments in plant and equipment, significant investments in labor or capital, or substantial investments in engineering, research and development, or licensing. The investments must further be directed to articles that practice a valid claim of the asserted patent. The investment component of the requirement is referred to as the “economic prong,” while the requirement that the article practices the asserted patent is referred to as the “technical prong.” The domestic industry requirement is codified in 19 U.S.C. § 1337(a)(2)-(3).
