Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V. v. Sirius XM Radio Inc.

Summary

The United States District Court for the District of Delaware considers, following remand from the Federal Circuit, whether Sirius XM Radio substantially relied on Fraunhofer-Gesellschaft’s misleading silence for purposes of equitable estoppel in a patent infringement dispute. After a bench trial, the Court finds that Sirius XM established reliance by a preponderance of the evidence through its consideration of Fraunhofer’s silence and its corporate practice of securing intellectual-property licenses. The excerpt concludes during the Court’s discussion of those findings.

Holdings

1. Sirius XM established by a preponderance of the evidence that it considered Fraunhofer's silence or inaction and that the silence influenced its decision to migrate to the accused high-band system rather than the noninfringing low-band alternative.
2. Sirius XM independently established reliance by showing that it continuously sought to secure intellectual-property licenses and would have sought a license or other protection against Fraunhofer's asserted patents had it known of the infringement exposure.
3. Because Sirius XM established the reliance element and the Federal Circuit had already determined that misleading conduct and material prejudice were established, Fraunhofer's infringement action was equitably estopped.

Questions Presented

1. Whether Sirius XM proved by a preponderance of the evidence that it relied on Fraunhofer's misleading silence, thereby satisfying the remaining element of equitable estoppel.
2. Whether Sirius XM established reliance through consideration of Fraunhofer's silence in its migration decision or through its corporate practice of continuously seeking licenses and taking steps to limit intellectual-property liability.
