The doctrine of collateral estoppel is a pivotal tool in the patent litigation landscape as it ensures finality and consistency in issues that have been previously adjudicated. In instances where parties find themselves contending with the same or related issues across different forums, it leads to a competitive dynamic—often described as a “race to the U.S. Court of Appeals for the Federal Circuit.” This situation has become increasingly common and raises strategic considerations for legal practitioners. Despite some ambiguities regarding when determinations from the Patent Trial and Appeal Board (PTAB) might trigger collateral estoppel, experts from Akin suggest that certain strategies can assist in navigating this complex procedural arena.
