It's kind of a cliche to knock on the door of the empty office. But we'd flown a long way. So we knocked. No one answered.When Patents Attack
The office was in a corridor where all the other doors looked exactly the same —locked, nameplates over the door, no light coming out. It was a corridor of silent, empty offices with names like "Software Rights Archive," and "Bulletproof Technology of Texas."
It turns out a lot of those companies in that corridor, maybe every single one of them, is doing exactly what Oasis Research is doing. They appear to have no employees. They are not coming up with new inventions. The companies are in Marshall, Texas because they are filing lawsuits for patent infringement.
Patent lawsuits are big business in Marshall, which is part of the eastern district of Texas.
