The Federal Circuit decided that Finjan had not presented substantial evidence that Blue Coat infringed the ‘968 patent. The court also agreed with Blue Coat that Finjan failed to apportion damages awarded for the ‘844 patent to the infringing functionality… This finding by the Federal Circuit reverses $7.8 million in damages related to infringement of the ‘968 patent awarded in district court. The Federal Circuit ruling on apportionment of damages awarded for the ‘844 patent will also cut into the largest portion of Finjan’s damages award.

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.
