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.

This appeal arises from an infringement action Ar- bmetrics, LLC (Arbmetrics) filed in the United States Dis- trict Court for the Southern District of California against Dexcom Inc. (Dexcom). Arbmetrics asserts that Dexcom’s Continuous Glucose Monitoring (CGM ) systems infringe U.S. Patent No. 6,343,225 (’225 patent). Based on the dis- trict court’s claim constructions of either “emulsion” or “ox- ygen dissolving substance,” the parties stipulated that Dexcom’s accused products do not infringe the ’225 patent.
