No. Patent trolls file in the eastern district of Texas not because the allegedly infringing products are sold there, but because the trolls have their "headquarters" there. If a product is found to be infringing, the decision is enforced nationwide.
If you own a patent, you file any infringement lawsuits in the jurisdiction in which you are domiciled (i.e., where you live, or if "you" are a corporation, the address at which the company is incorporated). Because the Eastern District of Texas is regarded as notoriously friendly to patent holders, a large number of non-practicing entities (NPEs) have incorporated there for the sole purpose of being able to bring suits in the district. A 2011 episode of the public radio program This American Life visited a nondescript office building in the small town of Marshall, Texas, just across the street from the federal courthouse, that is home to dozens of NPEs, all of which occupy locked and apparently permanently empty offices. These NPEs are corporate entities in name only, and exist only to own patents and bring infringement lawsuits in the Eastern District of Texas. Because the patent system is federal, however, any judgments handed down by the court apply nationwide. It doesn't matter where the products are sold.
