Evan Rothstein Quoted in Law360 on Key Midyear Patent Decisions

Evan Rothstein, co-chair of Arnold & Porter’s Intellectual Property practice, was quoted in the Law360 article, “Biggest Rulings For Patent Attys In 2026: A Midyear Report,” which examines several of the year's most significant patent decisions from the U.S. Supreme Court and the U.S. Court of Appeals for the Federal Circuit.

Evan discussed the Federal Circuit's decision in A.L.M. Holding Co. v. Zydex Industries Private Ltd., where he said the ruling provides "instructions" for patent owners when drafting exclusive license agreements to help ensure they have standing to bring infringement claims.

Evan also highlighted another Federal Circuit ruling that he described as a significant win for patent owners because it rejected a "per se, categorical rule" that would have barred consideration of non-infringing products in reasonable royalty analyses. He explained that where infringement of one component enhances the performance or value of related products, "I can use that ancillary benefit in the other parts of the stack in my calculation of what would be part of the hypothetical negotiation for reasonable royalties."
