On October 15, 2025, the United States Court of Appeals for the Federal Circuit issued a precedential decision concerning the assignment of patent rights in Causam Enterprises, Inc. v. International Trade Commission, No. 23-1769 (Fed. Cir. Oct. 15, 2025). In an appeal from the United States International Trade Commission’s investigation into Causam’s request to exclude certain internet-connected “smart” thermostats from importation and sale, the Federal Circuit concluded that the assignment in question, which recited continuation patent applications but not continuation-in-part patent applications, did not include the latter. This case serves as a reminder of the importance of securing clear and comprehensive assignments for all patent rights, particularly when subject matter is added to a patent application.

On December 4, 2024, the United States Patent and Trademark Office (“USPTO”) withdrew a proposed rule regarding terminal disclaimer practice to overcome non-statutory double patenting rejections. The proposed rule would have required a patentee to declare that the patent with the terminal disclaimer will be enforceable only if the patent is not tied to and has never been tied to a patent in which any claim has been finally held unpatentable or invalid as anticipated or obvious. Now, the USPTO has withdrawn the proposed rule, citing “resource constraints” as its reason not to move forward.
