From Bloomberg:
Toyota Motor Corp., the world’s biggest seller of autos powered by a combination of gasoline and electricity, faces a patent-infringement claim that may result in a U.S. import ban on its Prius and other hybrid models.
Closely held Paice LLC filed a complaint yesterday with the U.S. International Trade Commission in Washington, claiming Toyota is infringing its patent. The company seeks an order to ban imports of Toyota products using its invention.
For those who aren't familiar with this type of case, it's a Section 337 investigation. (HT to a customslawblog tweet).
