Polartec LLC, based in Lawrence, Mass., has filed a patent infringement complaint with the German District Court in Düsseldorf against Pontetorto SpA, a fabric manufacturer in Prato, Italy, and its German sales agent, Christian Weichert Internationale Textilvertretungen GmbH.


The complaint alleges that the defendants have infringed and continue to infringe on a European patent licensed exclusively to Polartec that is directed to grid-back, knit construction textiles by the sale of Pontetorto’s Technostretch products. In addition to monetary damages for patent infringement, Polartec’s lawsuit seeks an injunction preventing the sale of infringing products.
