ITC – Section 337

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.

Federal Circuit Reverses US$200M+ Jury Verdicts Because Asserted Claims Are Unpatentable Under § 101

According to 35 U.S.C. § 101, “any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof” may be patentable. Courts and litigants often struggle in determining what falls outside this scope—i.e., what is unpatentable subject matter. The Federal Circuit Court of Appeals dealt with this issue in a series of appeals between USAA v. PNC Bank (CAFC Nos. 2023-1639, 2023-1778, 2023-1866, 2025-1276, 2025-1277, and 2025-1341), held that the claims in the patents at issue recite unpatentable subject matter, and reversed the entries of judgment for the US$218M and US$4.3M jury verdicts that issued out of the Eastern District of Texas.

Oregon Enacts SB 951, Restricting PE-Backed MSOs in Physician Practice Transactions

On June 9, 2025, Oregon enacted Senate Bill 951 (SB 951), a sweeping new law significantly limiting how management services organizations (MSOs)—including those backed by private-equity firms—may engage with physician practices. The legislation targets traditional “friendly provider” models by restricting ownership and operational control of professional medical entities and voiding restrictive covenants. Investors must now reassess Oregon-based physician practice investments to ensure compliance by 2026 (for new MSOs) and 2029 (for existing ones). It’s noteworthy that this law will coexist with Oregon’s complicated health care transactions notice law, a law that requires a thorough review of certain health care transactions. ...Read more

The Patent Trial and Appeal Board (PTAB) is a tribunal within U.S. Patent and Trademark Office.
