I discussed inventor Gilbert Hyatt and his on-going litigation with the U.S. Patent and Trademark Office (“USPTO”) regarding his substantial patent portfolio in my Aug. 11, 2016, blog post. He is the inventor of a single-chip microcomputer in the 1960s and reportedly licensed his invention for more than $150 million. He is the named inventor on at least 70 patents.

The second prong concerns personal jurisdiction, which means that the accused infringer must establish that a federal district court has the authority to exercise its power over the defendant (i.e., the patent owner). This can be established by proving that the defendant had certain minimum contacts with the state in which the court sat.

A patent owner who attempts to inform a potential infringer about his or her patent rights runs the risk that the accused infringer might decide to file a declaratory judgment action. Through such an action, the accused infringer can seek to have a court declare that the accused infringer is not infringing the patent-at-issue. Alternatively, the accused infringer might seek to have the court declare that the patent is invalid.

The Supreme Court issued a decision in a criminal case in June that has implications in trade-secret law.
