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.

In this appeal, the parties dispute whether the pa- tentee was permitted to prove that the A ppellants’ prod- ucts infringed the claims of the asserted patent by showing that: (1) the patent claims are essential to mandatory as- pects of the Long-Term Evolution (“LTE”) standard; and (2) the accused products practice that standard.
