Intellectual Property Laws in Washington.
Core intellectual-property rights — patents, federal trademarks, and copyrights — are governed by federal law and enforced exclusively (patents and copyrights) or primarily (federal trademarks) in federal court. Patent and copyright claims for Washington-centered disputes are filed in the U.S. District Court for the Western or Eastern District of Washington. Washington state law adds the Washington Uniform Trade Secrets Act (RCW 19.108) and state-level trademark registration (RCW 19.77). Washington's concentration of technology employers (Microsoft, Amazon, Expedia, Nintendo of America, Valve, F5) makes it a high-volume IP venue.
