A new post-grant review proceeding at the Patent Trial and Appeal Board could be worth watching for companies and counsel operating in competitive consumer product and health-tech markets. In PGR2026-00051, titled Hyper Ice, Inc., a petitioner has asked the PTAB to review the validity of a recently issued patent associated with Hyper Ice, Inc. The petition was filed on May 26, 2026.

At this early stage, the PTAB docket signals the opening of a post-grant challenge, but practitioners should note that post-grant review itself already says a great deal about the patent at issue.
