The Verdict & Legal Analysis
Outcome
The Federal Circuit **affirmed** the district court’s ruling in favor of Simon Property Group and its co-defendants. AlexSam’s infringement action was dismissed, with the basis of termination recorded as **Appeal Dismissed**. No damages were awarded, and no injunctive relief was issued.
Key Legal Issues
The pivotal legal issue was the application of the **stipulated Datastream claim construction** — a previously agreed-upon interpretation of key claim terms derived from prior proceedings involving the same patent. This construction defined what constitutes an “unmodified” card-reading device within the scope of the ‘608 patent’s claims.
The Federal Circuit held that the district court **correctly applied** this stipulated construction. AlexSam failed to provide sufficient evidence to establish a genuine dispute of material fact regarding whether Simon’s accused card terminals and processing devices were “unmodified” within the meaning of the patent claims. The court found AlexSam’s additional arguments unpersuasive, reinforcing the binding nature of prior claim constructions and the high evidentiary standard for demonstrating infringement at the summary judgment stage.

U.S. Patent No. 6,000,608A, covering multifunction stored-value card processing technology, application number 08/891,261.
The court held that the district court correctly applied the stipulated Datastream claim construction and that AlexSam failed to produce sufficient evidence to raise a genuine dispute of material fact regarding whether Simon’s accused devices were “unmodified” under that construction.
It reinforces that stored-value card patent assertions face a high evidentiary bar when operating under restrictive stipulated claim constructions, and that multi-party defendants can effectively consolidate around favorable prior rulings.
