Traxcell Technologies, LLC v. Sprint Communications Company, No. 20-1852 (Fed. Cir. Oct. 12, 2021)

From the Opinion

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.

Traxcell1 sued Sprint2 and Verizon3 for infringement of four patents related to self -optimizing wireless networks and to navigation technology. After claim construction and discovery, the district court granted summary judgment for Sprint and Verizon. Traxcell appeals. For the reasons be- low, we agree with the district court’s claim construction . We also agree that under that construction, Traxcell failed to show a genuine issue of material fact as to infringement and that several of Traxcell’s claims are indef inite. We therefore affirm.
