The U.S. Court of Appeals for the Federal Circuit (CAFC) on Friday upheld an Arkansas district court’s decision to grant Morris & Associate Inc.’s motion for summary judgment against John Bean Technologies Corporation’s infringement claims, based on the doctrine of equitable intervening rights. The opinion marked the first time the court has addressed the “boundaries of the phrase ‘protection of investments’ in [35 U.S.C.] § 252”, which outlines the effect of reissued patents.  

On Friday, May 11th, U.S. District Judge Edward Davila entered an order deciding motions made in a copyright case involving competing musical productions based on the fictional story of the fictional folk hero Zorro. Judge Davila’s orders allows copyright infringement claims asserted by a writer who developed a Zorro musical in the 1990s to move forward against Zorro Productions, the entity which had licensed the Zorro character to entertainment companies going back to the late 1940s. This case is in the Northern District of California.

On Thursday, April 20th, the Court of Appeals for the Federal Circuit issued a decision in Medinol Ltd. v. Cordis Corporation et. al. which vacated and remanded a lower court’s ruling that claims of patent infringement alleged by Israeli pharmaceutical firm Medinol were barred by the equitable defense of laches. The Federal Circuit’s decision comes after the U.S. Supreme Court overturned the Federal Circuit’s previous precedence on laches as an equitable defense in SCA Hygiene Products v. First Quality Baby Products, decided last year. The case was decided by a panel consisting of Circuit Judges Timothy Dyk, Jimmie Reyna and Kara Stoll.

Equitable estoppel does not bar assertion of patent claims later amended by reexamination when those new claims differ in scope from earlier claims in the patent that were not asserted. Thus, a defendant’s reliance on a patentee’s knowing silence and failure to enforce an earlier patent does not shield him from allegations of infringing later-issued claims of different scope.

It is that time once again when we look back on the previous year in preparation to close the final chapter of 2017 in order move fresh into the year ahead. 2017 was a busy year in the patent world, although change was not as cataclysmic as it had been in past years, such as 2012 when the PTAB and post grant challenges began, in 2013 when AIA first to file rules went into effect, or in 2014 when the Supreme Court decided Alice v. CLS Bank. It was, nevertheless, still an interesting year… To come up with the list below I’ve reviewed all of our patent articles, and have come up with these top 10 patent stories for 2017. They appear in chronological order as they happened throughout the year.

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.

Without laches, accused infringers might more frequently invoke declaratory judgment to clear their products and services upfront rather than tolerate a looming threat of suit for years…. The Supreme Court’s recent decision in SCA Hygiene Products Aktiebolag v. First Quality Baby Products, LLC (Mar. 21, 2017) eliminated the equitable defense of laches in patent cases.  While time will reveal the impact of the SCA decision, elimination of laches, an equitable defense against “unreasonable, prejudicial delay in commencing suit,” Id. at 3 (citing Petrella v. Metro-Goldwyn-Mayer, Inc.(2014), provides greater security to patent owners who assert claims several years after discovering potential infringement.  Conversely, the decision removes one shield—albeit a relatively modest shield—from the accused infringer’s armament of potential defenses. 

The remaining vitality of estoppel as a defense against patent infringement after SCA Hygiene Products is also not a hypothetical question. Indeed, the issue of estoppel remains very much “alive and well” in SCA Hygiene Products. Besides laches, the accused infringer in SCA Hygiene Products, First Quality Baby Products, had moved (not surprisingly) for summary judgment based upon an estoppel defense, which was also granted by the district court. Also not too surprisingly, that portion of the ruling by the district court was reversed and remanded by the Federal Circuit panel on the ground that there were “genuine issues of material fact” to be resolved. The Federal Circuit majority in its en banc ruling also reinstated and preserved the Federal Circuit panel’s reversal and remand of the district court’s grant of summary judgment on the estoppel defense. Finally, in footnote 2, SCOTUS’ decision in SCA Hygiene Products expressly states: “We do not address the Federal Circuit’s reversal of the District Court’s equitable estoppel holding.”

In a strong reversal of the Federal Circuit, the US Supreme Court held in SCA Hygiene Products Aktiebolag v First Quality Baby Products, LLC, No. 15-927 (March 21, 2017), that delay by a patentee will not give rise to a laches defense during the statutory six-year damages period under 35 U.S.C. § 286. Justice Samuel Alito authored the 7–1 majority opinion, extending the court’s decision in Petrella v. Metro-Goldwyn-Mayer, Inc. (2014), which held that laches is inapplicable for copyright infringement, a provision similar to Section 286 of the Patent Act… The Supreme Court noted that its determination regarding laches does not preclude a defense based on equitable estoppel…

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.

On Tuesday, March 21st, the U.S. Supreme Court issued a decision in SCA Hygiene Products Aktiebolag v. First Quality Baby Products, LLC, a case which looked at the issue of whether and to what extent the defense of laches may bar a claim for patent infringement brought within the six-year statutory limitations period, as defined by 35 U.S.C. Section 286. In a 7-1 vote, the Supreme Court decided that the equitable defense of laches cannot be invoked against claims for infringement occurring during the statutory period.

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.

On the heels of a busy term last year, the stage is set for the Supreme Court to review two more important issues regarding utility patents during the October term. The first issue involves one aspect of the Federal Circuit’s decision in Promega Corp. v. Life Technologies Corp., 773 F.3d 1338 (Fed. Cir. 2014) — i.e., whether a party who supplies a single, commodity component of a multi-component invention from the United States can be liable for infringement. The second issue arises from SCA Hygiene Prods. Aktiebolag v. First Quality Baby Prods., LLC, 807 F.3d 1311 (Fed. Cir. 2015) (en banc), to determine whether laches remains a viable defense to patent infringement with respect to pre-litigation damages in certain circumstances.
