Narrative Opinion Summary
The case involves a patent infringement lawsuit brought by Blue Calypso entities against Groupon, IZEA, Foursquare, and Yelp, concerning three patents related to peer-to-peer advertising systems. Key legal issues revolved around claim construction principles, particularly the interpretation of terms like 'endorsement tag' and 'qualified subscriber.' The case's procedural history includes a stay for Covered Business Method Review, followed by claim construction briefings. The court applied principles from Phillips v. AWH Corp., emphasizing intrinsic evidence from the patent specifications and prosecution history while resolving disputes over claim terms. It ruled that certain preambles are limiting, contributing essential structure to the claims. The court provided constructions for various terms, including 'subsidy,' which it interpreted broadly to include financial assistance forms like discounts. The court rejected defendants' proposals for more restrictive interpretations that could exclude certain patent embodiments. The decision mandates mediation between the parties, reinforcing the broad scope of claim language and the necessity of precise legal interpretations in patent disputes.
