The United States District Court for the Eastern District of Texas described by the NYT is known as the "rocket docket" and the go-to forum for patent trolls.
A friend who is a patent litigator in a major US IP law practice, recently was moved to TX to be near the Court's location. Relocation driven by the disproportionate economic activity surrounding that jurisdiction.
Hope the Supremes will do something to mitigate the disproportionate influence of the Eastern District Court in patent matters.
