The passage below is extracted verbatim from the opening of the document. It has not been editorially summarized — consult the full opinion for the court's complete reasoning.

Before the Court is Plaintiff Robert Bosch LLC’s Motion to Compel Defendant Westport Fuel Systems Canada, Inc. to Substantively Respond to Interrogatory No. 20 Regarding Invalidity of the ’138 Patent for Obviousness-Type Double Patenting (Dkt. No. 151), for which t he Court held a hearing on November 5, 2025. Bosch argues that it timely disclosed an obviousness -type double patenting (“ODP”) invalidity theory against Westport’s asserted U.S. Patent No. 6,575,138, but that Westport has failed to answer Bosch’s Interrogatory No.
