Specifically, the petition presents the question: is patent ineligibility under 35 U.S.C. § 101, which Congress did not codify in 35 U.S.C. § 282(b), not a cognizable defense in a patent litigation? The question presented parallels that of the one recently decided by the Supreme Court in SCA Hygiene Products Aktiebolag v. First Quality Baby Products, LLC, 137 S. Ct. 954 (2017). In SCA Hygiene, the Supreme Court examined 35 U.S.C. § 282(b), which enumerates the defenses that may be raised in a patent litigation, and held that laches, which is not recited in § 282(b), is not a defense to patent damages within the statute of limitations set forth in 35 U.S.C. § 286. RPost’s petition asks the Court to again examine § 282(b) in order to determine whether patent ineligibility under 35 U.S.C. § 101, which, like laches, is not recited in § 282(b), is similarly not a defense that may be raised in a patent litigation.

Equitable estoppel may be appropriate for the defendant in SCA v. First Quality since the plaintiff was silent for years after the defendant asserted invalidity (possibly fulfilling the misleading conduct through inaction and reliance on that conduct). But can equitable estoppel be relied upon as a defense against a dormant plaintiff in the example illustrated above? Below, we consider the two elements of equitable estoppel that replace the unreasonable delay element of laches: misleading conduct and reliance.

The fact that laches cannot be used as a defense to a patent infringement action brought during the statute of limitations is most definitely a pro-patent decision. Presently patents are much weaker than they have been at any time over the last 36 years. But patent law has always swung like a pendulum, and this low point will not last forever. Thus, in the wake of the Supreme Court’s decision in SCA Hygiene, patent owners would do well to consider forgoing patent enforcement. Instead, allow infringement to accrue and then sue for infringement in several years when the law may be quite a bit more favorable. After all, patents can last for 20 years, the statute of limitations is six-years, and without a laches defense available to infringers you will be able to seek damages going back six years from whenever you choose to sue.

The equitable defense of laches has been a useful tool for defendants in intellectual property litigation for over a hundred years, but a recent case in the U.S. Supreme Court could potentially remove the defense in patent infringement cases. In SCA Hygiene Products AB v. First Quality Baby Products LLC, the Supreme Court must decide whether the doctrine of laches bars patent infringement claims filed within the six-year statutory limitation period established under 35 U.S.C. § 286 of the Patent Act… Based on oral arguments, it is expected the Court will reverse the Federal Circuit’s decision and conclude that laches do not apply to patent infringement cases brought within the six-year damages period.

The stage is now set for the Supreme Court to weigh in on the future of laches in patent litigation. If the Court closely follows its analysis in the Petrella decision, it is fairly likely that the Court will reverse the Federal Circuit and hold that laches cannot bar claims for damages within the six-year period set forth in § 286. Indeed, given the en banc ruling, it is unlikely that the Court would grant certiorari simply to confirm that Aukerman remains good law. There is also the conspicuous absence of the term “laches” (or any other reference to “equitable” defenses) in the Patent Act. While the Federal Circuit found that the doctrine of laches was implied by the language of § 282, the Supreme Court may not be so willing to entertain the same statutory interpretation.
