Prepare for More Estoppel if the Supreme Court Reverses Federal Circuit on Partial IPR Institutions

Partial institutions lessen the value of estoppel because the petitioner avoids estoppel on claims that were challenged but not instituted. The PTAB never issues a final written decision for these challenged-but-not-instituted claims. And because estoppel only applies to claims receiving a final written decision, these non-instituted claims escape the estoppel statute See, e.g., Shaw Industries Group v. Automated Creed Systems, 817 F.3d 1293, 1300 (Fed. Cir. 2016). In effect, the PTAB’s current practice saves a petitioner from estoppel on claims it had little chance of invalidating. Thus, under the current practice, a petitioner currently only risks estoppel on claims that it stands a good chance of invalidating. But if the Supreme Court decides as expected, estoppel will attach to all challenged claims of an instituted IPR. Final written decisions will more often include claims found valid, and a petitioner will no longer be able to avoid estoppel for some claims by relying on the PTAB to sort strong challenges from weak ones at the institution stage.

Recent court rumblings about a narrow scope of IPR estoppel

An Inter Partes Review (IPR) is an important tool for companies that face frequent patent infringement challenges. An IPR is essentially a mini-litigation focusing solely on patent validity conducted before a panel of administrative patent judges sitting in the Patent Trial and Appeal board (PTAB). Once an IPR is initiated, a decision on validity is issued within one year. The narrow focus, fast timing, and lower cost of an IPR, along with certain legal advantages that make proving invalidity easier in an IPR than in a district court, make it an attractive alternative to district court litigation when good invalidity arguments are available.
