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.

ANTENNASYS, INC. v. AQYR TECHNOLOGIES, INC. 2 There is little more frustrating for a district court judge than to have the parties jointly lead you down a wrong, and possibly unnecessary, path. That is what occurred here. Unfortunately, many threshold issues that may have obviated the need for either claim c onstruction or an in- fringement verdict remain unresolved. At first blush, this is a patent infringement case, with the only dispute before us concerning the district court’s construction of one claim term in United States Patent No.
