In Re Koninklijke Philips Patent Litigation

Background

Koninklijke Philips N.V. and U.S. Philips Corp. sued over alleged infringement of eleven patents. Microsoft later intervened in actions involving several defendants, and Philips asserted counterclaims against Microsoft for infringement of nine patents. Two patents at issue were U.S. Patent No. 7,184,064 (the “’064 Patent”) and U.S. Patent No. 6,690,387 (the “’387 Patent”), which concern techniques for scrolling content on a touch screen. The ’064 Patent is a continuation of the ’387 Patent.

After an inter partes review—a review of patent validity conducted by the Patent Trial and Appeal Board—the Board issued a decision finding all claims of the ’387 Patent unpatentable based on obviousness. Philips indicated that it intended to appeal that decision to the Federal Circuit. Microsoft asked the court to stay, or pause, the claims and counterclaims related to the ’064 Patent while that appeal was pending. Microsoft alternatively sought permission to file an early motion for summary judgment, but the opinion’s operative ruling grants the stay motion.

The Court’s Analysis

The court applied three factors used to decide whether to pause litigation during patent-office proceedings:

1. Stage of the case. Philips argued that fact discovery was complete and trial was set for February 2020. The court acknowledged the parties’ substantial work but found that the case was not so advanced that a partial stay was unwarranted. Dispositive-motion and expert-evidence hearings had not yet occurred, and the pretrial conference was still approximately three months away. This factor weighed slightly in favor of a stay.

2. Whether the stay would simplify the case. Microsoft argued that the ’064 and ’387 Patent claims were nearly identical. The court did not conclusively decide whether a Federal Circuit affirmance would prevent relitigation of the ’064 Patent’s validity, a legal effect sometimes called collateral estoppel. But it found potential for that effect and concluded that the Federal Circuit’s decision could greatly simplify the litigation. If the Federal Circuit reversed the Board’s decision, the parties could resume litigating the ’064 Patent claims without resolving the collateral-estoppel issue. This factor favored a stay.

3. Undue prejudice or tactical disadvantage. Philips argued that Microsoft delayed raising the issue despite knowing about the Patent Trial and Appeal Board proceedings and that Microsoft could gain an advantage by watching related litigation while its own claims were paused. The court declined to find a delaying motive because Microsoft filed its motion about a month after the Board’s final decision and about two weeks after Philips dismissed the ’387 Patent. The court also found that Microsoft’s situation was not different from other cases in which litigation involving the same or similar patents proceeds at different times. This factor favored a stay.

Order

The court granted Microsoft’s motion to stay all claims related to the ’064 Patent pending a Federal Circuit order affirming or reversing the Board’s decision regarding the ’387 Patent. The court stated that it would consider lifting the stay after the Federal Circuit issued a final order and would not continue the stay while petitions for rehearing were pending. Microsoft and Philips were directed to submit a joint status report every 180 days about the Federal Circuit proceeding and another report within five days after the Federal Circuit issued its decision.

The opinion’s text-recognition is unclear in one line of the conclusion where the patent number is obscured, but the surrounding discussion identifies the relevant Patent Trial and Appeal Board decision as involving the ’387 Patent.
