Study notes for Blonder-Tongue Laboratories, Inc. v. University of Illinois Foundation: professor notes, cold call prep, exam angles, and memory aids.

Defensive collateral estoppel may apply to parties not involved in prior litigation if they had a full opportunity to litigate the issues previously adjudicated.
Professor Notes

In Blonder-Tongue Laboratories, Inc. v. University of Illinois Foundation, the U.S. Supreme Court addressed the applicability of non-mutual defensive collateral estoppel in patent law. The significance of this case lies in its expansion of the doctrine beyond the traditional requirement of mutuality. The Court emphasized that even if a party was not involved in the previous suit, they could be precluded from litigating an issue previously determined against another party if they had a full and fair opportunity to litigate that issue in the prior proceeding. This ruling reinforces judicial efficiency and finality in patent litigation, which is crucial given the resource-intensive nature of patent lawsuits.
