Just to repeat, we're not lawyers and we sued Disney and MLB, Sanrio, United Media on our own.
A bit after we were through with all these companies (we had gone through everyone whose fabric we were using) the Stanford School of Law used us as a class project. They provided us with a sample suit and a motion for summary judgement which are on the site.
A seller I know who got shutdown by Laurel Burch used the Stanford law suit and backed down Laurel Burch.
