Judge Stark Denies Attempt to Extend Stay Pending IPR to Include Appeal to the Federal Circuit

In late 2013, Chief Judge Stark granted a motion to stay this case pending an inter partes review by the PTO based, in part, on the argument that the stay would not exceed 18 months, given the statutory deadlines for IPRs, and the defendant’s withdrawal of its prior opposition after the IPR was instituted. Zoll Medical Corp. v. Respironics, Inc., C.A. No. 12-1778-LPS, Memo. Or. at 1-2 (D. Del. July 8, 2015). Recently, the PTO confirmed patentability of eight claims of the patent-in-suit, with one claim having been cancelled in the IPR. Plaintiff Zoll sought to lift the stay of this litigation and Defendant Respironics opposed, arguing that it would appeal the finding of patentability to the Federal Circuit. Id.

As Judge Stark explained, “[u]nderstandably, Zoll now wishes to proceed with the litigation it filed more than 2 ½ years ago . . . . The proper exercise of the Court’s discretion under these circumstances is to lift the stay and proceed with the litigation, just as the parties (and the Court) envisioned at the time the unopposed motion to stay was granted. The IPR proceeding is complete and the stay has been in place nearly 19 months. Respironics has pointed to no new, unforeseeable events to cause the Court to depart from the path that was set when the stay was imposed. As Zoll puts it, ‘Having taken its shot in the USPTO and failed, Respironics should not be able to preclude Zoll from pursuing its claims in this court for an indeterminate period of time.’” Id. at 2.

Respironics’ appeal to the Federal Circuit was not a persuasive reason to keep the stay in place: “The pendency of an appeal from the IPR, and the possibility that the Federal Circuit may reverse the PTO (and thereby simplify this litigation by, presumably, making it disappear), is not, in and of itself, a sufficient basis to make the patentee here continue to wait to enforce patent rights that it currently holds.” “Had Respironics initially been seeking a stay that would extend to the period during which any appeal from the IPR would be pending, it is likely Zoll would have continued to oppose the motion, and the Court’s calculus might very well have differed too.” Id. at 2-3.
