That probably seems like a bizarre Craigslist ad. It’s not real—we mocked it up for this article. Still, and startlingly, it accurately portrays what’s happening in the Waco Division of the U.S. District Court for the Western District of Texas. One judge, appointed to the Western District only three years ago, has been advertising his courtroom through presentations to patent lawyers, comments to the media, procedural practices, and decisions in patent cases as the place to file a patent infringement lawsuit. That advertising has succeeded. In 2016 and 2017, the Waco Division received a total of five patent cases. In 2020, nearly eight hundred patent cases—more than 20 percent of all patent cases nationwide—were filed there.
