Beware Equitable Doctrine of Issue Preclusion in Multiparty, Multivenue Patent Campaigns

by | Aug 1, 2024 |

Addressing for the first time whether an invalidity order merges with a voluntary dismissal for purposes of finality, the US Court of Appeals for the Federal Circuit held that an interlocutory order merges with the final dismissal, rendering the interlocutory order final for purposes of issue preclusion. Koss Corp. v. Bose Corp., Case No. 22-2090 (Fed. Cir. July 19, 2024) (Hughes, Stoll, Cunningham, JJ.). As a consequence, the Federal Circuit found that the patent owner’s appeal from an adverse decision in an inter partes review (IPR) was moot under the doctrine of nonmutual collateral estoppel.

In July 2020, Koss filed a patent infringement lawsuit against Bose in the Western District of Texas, asserting three patents whose common specification discloses a “wireless earphone that communicates with a digital-audio source, such as an iPod, over an ad hoc wireless network like Bluetooth.” The same day, Koss asserted the same patents against Plantronics. Bose filed a motion challenging venue and also petitioned for inter partes review (IPR) of the three patents. Later in 2020, Bose filed a declaratory judgment action seeking a declaration of noninfringement in the District of Massachusetts on the three patents Koss asserted against Bose in the Texas litigation. The Massachusetts litigation was stayed pending the resolution of the venue motions in the Texas case.

In 2021, the Texas court dismissed Koss’s complaint against Bose for improper venue. Koss then asserted a counterclaim of infringement of the same three patents in the Massachusetts litigation. The Massachusetts court again stayed the litigation pending the resolution of the IPRs, which (by that time) the Patent Trial & Appeal Board had instituted. Meanwhile, Koss’s case against Plantronics was transferred to the Northern District of California, and Plantronics moved to dismiss the complaint on the ground that all the asserted claims (which included all the claims asserted against Bose) were invalid under 35 U.S.C. § 101. The California court granted Plantronics’s motion, rendering all the asserted claims invalid. However, that order did not finally dispose of the case.

Koss then moved for leave to amend its complaint, which the California district court granted. In the amended complaint, Koss asserted two additional patents. Plantronics moved to dismiss the asserted claims in those patents as invalid under § 101. The parties fully briefed Plantronics’s motion, but before the district court issued a decision on the merits of that motion, Koss voluntarily stipulated to dismissal with prejudice, disposing of the lawsuit in its entirety. Koss did not ask the district court to vacate its earlier order finding certain claims invalid under § 101. The California district court then issued an order dismissing the case with prejudice. The deadline for Koss to appeal the judgment came and went – Koss did not appeal.

Arguing that the patents had been finally adjudicated invalid in the Plantronics litigation, Bose moved to dismiss Koss’s appeal from the Board in the IPR proceedings as moot. Koss opposed the motion, arguing that its amended complaint rendered the invalidity decision on the prior complaint non-final because the [...]

Don’t Ruin Today’s CNS with Yesterday’s Problems

by | Aug 10, 2023 |

The US Court of Appeals for the Fifth Circuit reversed a district court’s trademark invalidity finding based on lack of subject matter jurisdiction because a covenant not to sue (CNS) issued by the trademark owner precluded any reasonably expected future injury that the alleged infringer might incur. Nursery Decals & More, Inc. v. Neat Print, Inc., Case No. 22-10065 (5th Cir. Aug. 1, 2023) (Haynes, Engelhardt, JJ.; deGravelles, Dist. J., sitting by designation) (per curiam).

Neat Print and Nursery Decals sold novelty t-shirts on online marketplaces. In 2018, Neat Print notified one of the online marketplaces that Nursery Decals’ products allegedly infringed Neat Print’s trademarks. In response, the online marketplace sent Nursery Decals a final warning threatening a site ban for any future violations. Nursery Decals complied with the warning and also preemptively pulled its products from other online marketplaces.

Nursery Decals sued Neat Print in the Northern District of Texas. Most of Nursery Decals’ claims were directed to invalidating Neat Print’s trademarks or obtaining a noninfringement judgment. Nursery Decal also included three claims seeking damages. One was a federal claim for fraud on the US Patent & Trademark Office (PTO). The other two claims were Texas law claims based on tortious interference with an existing business relationship and a prospective business relationship. The district court ultimately granted summary judgment on all of the trademark-related claims, ordering the PTO to cancel all of the disputed trademarks.

Prior to the district court’s summary judgment grant, Neat Print tried to avoid summary judgment by filing a CNS along with a motion to dismiss for lack of subject matter jurisdiction. The district court denied the motion to dismiss, concluding that the CNS did not moot the case. The district court explained that Neat Print’s CNS did not address Nursery Decals’ past and potential future injuries (i.e., Nursery Decals’ damages claims). The district court also found that Neat Print’s CNS did not meet the high standard set forth in the Supreme Court’s 2013 decision in Already, reasoning that Neat Print’s CNS left the door open for future take-down notices based on the disputed trademarks.

Neat Print amended its CNS to address take-down notices. It then filed a motion to reconsider its motion to dismiss in light of the modified CNS. The district court orally denied the motion at the pretrial conference and ordered that the case proceed to trial. The jury ultimately found no liability on both claims. After the trial, the district court issued a written opinion explaining that it rejected Neat Print’s motion for reconsideration because Nursery Decals had a legally cognizable injury that supported subject matter jurisdiction. While Neat Print had defeated all of Nursery Decals’ damages claims, Neat Print appealed the district court’s judgment with respect to the trademark claims, arguing that the district court failed to properly evaluate subject matter jurisdiction on a claim-by-claim basis in view of Neat Print’s CNS.

The Fifth Circuit agreed with Neat Print, finding that the district court committed two errors. First, the district [...]

Mootness Requires Covenant Not to Sue to Be Unconditional and Irrevocable

by | Jun 29, 2023 |

Addressing a district court decision finding no trade secret misappropriation, the US Court of Appeals for the Fourth Circuit agreed that the alleged trade secret holder had failed to moot the case because its covenant not to sue was both conditional and revocable. Synopsys, Inc. v. Risk Based Security, Inc., Case No. 22-1812 (4th Cir. June 15, 2023) (Agee, Rushing, Dawson, JJ.)

In early 2021, Risk Based Security (RBS) sent a cease-and-desist letter to Synopsys, its competitor in the software security industry, alleging intellectual property misappropriation, including use of RBS’s private database of source code vulnerabilities. Synopsys responded by filing a declaratory judgment action asserting that it had not engaged in trade secret misappropriation. RBS later issued a covenant not to sue in express reliance on certain pretrial representations made by Synopsys, including that Synopsys was not planning to use RBS’s database. RBS moved to dismiss the case as moot based on its covenant, but the district court denied the motion. The district court then ruled on summary judgment that RBS had failed to establish that its alleged trade secrets satisfied the requirements that they have an independent economic value derived from their secrecy and were subject to reasonable efforts to maintain their secrecy. RBS appealed.

The Fourth Circuit first affirmed the rejection of RBS’s covenant not to sue. The Court noted that the covenant was not unconditional and irrevocable because it was expressly premised on Synopsys’s planned future performance, which RBS could later claim was not being met. The Court also relied on the fact that the covenant was limited to the use of RBS’s private database and was thus narrower than the original cease-and-desist letter, which was explicitly not limited to that use. Finally, the Court concluded that there was a continuing live controversy, demonstrated by the fact that, after issuing the covenant, RBS added Synopsys to a pending trade secret case it had filed against Synopsys’s subsidiary. Accordingly, the Fourth Circuit affirmed the district court’s denial of RBS’s motion to dismiss.

On the merits, the Fourth Circuit agreed with the district court that RBS had failed to show that its alleged trade secrets met the independent value or reasonable secrecy elements required by statute. In particular, the Court agreed that RBS’s evidence regarding its value as a company and the revenue it derived from licensing its database could not show independent value for the specific alleged trade secrets contained in the database.

Since Vacatur Seeks Equitable Relief, Clean Hands Matter

by | Jun 30, 2022 |

In an opinion related to its 2021 ruling that a decision in earlier inter partes reexaminations of related patents had a preclusive effect that collaterally estopped the Patent Trial & Appeal Board (Board) from making new findings on the same issue, the US Court of Appeals for the Federal Circuit vacated the Board’s decision on remand since the patent at issue expired. SynQor, Inc. v. Vicor Corp, Case No. 20-1259 (Fed. Cir. Jun. 17, 2022) (Chen, Prost, JJ.), (Lourie, J., dissenting) (non-precedential).

Background

After being sued by SynQor, Vicor petitioned for reexamination of several SynQor patents (including the ’021 and ’190 patents). In the ’190 patent reexamination proceeding, Vicor successfully argued that the ’190 patent claims (including new claims sought to be added by SynQor) were unpatentable over two references. After appeals to the Board (which reversed the examiner) and Federal Circuit (which reversed-in-part, vacated-in-part), the case was remanded to the Board to consider the examiner’s obviousness rejections in light of the Court’s conclusion that prior art patents anticipated certain claims.

On remand, the Board affirmed almost all of the examiner’s rejections and applied a new ground of rejection to one of SynQor’s proposed new claims. However, before the Board issued its final decision regarding the new claims, the ’190 patent expired and SynQor appealed to the Federal Circuit to vacate the Board’s decisions regarding the new claims on the ground that the ’190 patent’s expiration rendered the Board’s patentability decision moot. The Court agreed and vacated the Board’s decisions, explaining that the inability to issue the new claims meant that “the Board’s patentability determinations were unreviewable for mootness” since the Court would be “frustrated by the vagaries of circumstance” (thereby falling under the Supreme Court’s Munsingwear doctrine) from reviewing the Board’s determinations on the merits.

Similarly, in the ’021 patent’s reexamination, the examiner rejected all challenged claims, including two new claims that SynQor proposed. The Board affirmed the examiner’s rejections, and on appeal the Federal Circuit affirmed-in-part, vacated-in-part and remanded for the Board to reconsider two obviousness grounds it deemed the Board had unjustifiably reached inconsistent conclusions on (relative to a separate reexamination proceeding for another related patent). On remand, the Board again found SynQor’s proposed new claims unpatentable, unaware that the ’021 patent had expired over a year prior. In its rehearing petition, SynQor informed the Board of the ’021 patent’s expiration and asked the Board to vacate its decision on the merits. SynQor appealed after the Board declined to do so.

Appeal on the ’021 Patent

On appeal, SynQor requested that the Federal Circuit vacate the Board’s decision (for the same reasoning as in the ’190 patent appeal). Vicor argued that the Court lacked Article III jurisdiction to consider the request, and that SynQor was not entitled to equitable relief because of its failure to inform the Board of the ’021 patent’s expiration date, which caused the remand decision to be issued. Vicor also argued that the timing of the ’021 patent expiring before [...]

Failing to Address All Reasons for Noninfringement Renders Appeal Moot

by | Oct 14, 2021 |

In deciding whether the district court correctly interpreted various claim terms in four patents related to communication techniques used in computer gaming technology, the US Court of Appeals for the Federal Circuit found that rendering a decision as to the terms for at least two of the patents would be moot. Accordingly, the Federal Circuit affirmed the district court’s grant of summary judgment on noninfringement. Acceleration Bay LLC v. Take-Two Interactive Software (Oct. 4, 2021) (Reyna, J.)

Acceleration Bay is the owner of four unrelated patents that are generally directed to communication techniques associated with computer gaming. In particular, certain of the patents teach that an originating computer sends a message to its neighbors on a broadcast channel using point-to-point connections, and that the neighboring computers then sends the message to only their neighboring connections. This reduces the number of connections that each computer must maintain and improves efficiency in the system.

Acceleration Bay filed a patent infringement suit claiming that Take-Two Interactive Software, a software designer for various video games, including Grand Theft Auto V, NBA 2K15 and NBA 2K16, directly infringed the four asserted patents. As part of the district court proceedings, multiple terms recited in the claims of the four patents were construed. In particular, the court construed the claim term “m-regular” to mean “a state that the network is configured to maintain, where each participant is connected to exactly m neighbor participants.” Additionally, the court effectively embedded this definition of “m-regular” into other construed claim terms, including “fully connected portal computer” and “each participant being connected to three or more other participants.”

After claim construction, the district court granted summary judgment of noninfringement in favor of Take-Two on all asserted patents. In granting summary judgment, the court observed that Take-Two makes software, not computer networks or broadcast channels, and therefore its customers must introduce those elements. As such, direct infringement is inappropriate because multiple entities, not just Take-Two, contribute to the allegedly infringing system. The court rejected Acceleration Bay’s argument under Centrak, Inc. v. Sonitor Techs., Inc. that Take-Two was actually the “final assembler” because it installed the software for its customers. The court additionally identified multiple reasons why the “m-regular” limitation was not met in the accused products, including the fact that Acceleration Bay identified no source code to support its theory. Acceleration Bay appealed.

With respect to two of the four patents on appeal, Take-Two argued that Acceleration Bay’s appeal is moot because it only addressed one of the two reasons the district court granted summary judgment of noninfringement. Specifically, the court granted summary judgment on these two patents because (1) the accused products do not meet the “m-regular” limitation and (2) Acceleration Bay’s “final assembler” theory fails as a matter of law. On appeal, Acceleration Bay addressed only the “final assembler” theory. As such, the Federal Circuit found that a ruling on this issue would not affect the court’s summary judgment ruling, and the appeal of these two patents is [...]

A Shoe-In? Fleet Feet Gives Injunction Appeal the Moot Boot

by | Feb 11, 2021 |

The US Court of Appeals for the Fourth Circuit dismissed a preliminary injunction as moot where the enjoined party had discontinued the use complained of and had no future plan to restart it. Fleet Feet, Inc. v. Nike, Inc., Case No. 19-2390 (4th Cir. Jan. 26, 2021) (Diaz, J.) The Court denied the enjoined party’s request that it vacate the district court’s order granting the preliminary injunction despite mootness due to an ongoing litigation.

Fleet Feet is a retailer selling products related to running, including Nike merchandise. It is also a Nike competitor since Nike sells its own products. Fleet Feet obtained two trademark registrations, having already used both for years: “Running Changes Everything” in 2020, and “Change Everything” in 2015. In July 2019, Nike launched an advertising campaign with the tagline “Sport Changes Everything” scheduled to end at the February 2020 Super Bowl. Fleet Feet sued Nike for trademark infringement. The district court granted a preliminary injunction against Nike and set a $1 million injunction bond. The preliminary injunction order prohibited Nike from any use of the phrase “Sport Changes Everything” or any other designation confusingly similar to the Fleet Feet’s marks when advertising or selling goods and services. Nike discontinued its campaign two months before the scheduled end and appealed the preliminary injunction order.

Nike argued that the district court erred in its preliminary injunction factor analyses. But on appeal, the Fourth Circuit decided as a threshold matter that the end of Nike’s “Sport Changes Everything” campaign and its representation that there were no plans to use the term after the campaign rendered Nike’s appeal of the preliminary injunction “designed to interrupt that very campaign” moot. A case becomes “moot” when the “issues presented are no longer ‘live’ or the parties lack a legally cognizable interest in the outcome.” The Court found that Nike’s appeal of the preliminary injunction was nonjusticiable since there had been an event during the pendency of the appeal that made it impossible to grant effective relief to a prevailing party. Because of the conclusion of the 2020 Super Bowl and Nike’s representations that it did not plan to use the term afterwards, there was no possible relief to Nike based on the preliminary injunction’s interference with the campaign.

The Fourth Circuit disagreed with Nike that two issues remained live. First, Nike argued that the continued restraint on Nike’s speech due to the order’s prohibition of any confusingly similar designation to Fleet Feet continued to be a live issue. The Court explained that this was only a potential controversy, not a live controversy. Because Nike had not engaged in the speech barred by the order, had represented that it did not intend to do so in the future, and had not introduced any new slogans confusingly similar to Fleet Feet’s marks, no actual speech was threatened by the preliminary injunction.

Second, Nike argued that the potential recovery on the injunction bond was a live issue. Referring to the Supreme Court case Univ. of Tex. [...]

PTAB May Reject Substitute Claims Under Any Basis of Patentability

by | Aug 5, 2020 | ,

The US Court of Appeals for the Federal Circuit considered for the first time whether a district court’s invalidity determination, when made final after all appeals are exhausted, divests the Patent Trial and Appeal Board (PTAB) of jurisdiction in a co-pending inter partes review (IPR) proceeding involving the same claims, and held that it does not. The Court also held that in an IPR proceeding, the PTAB is free to reject proposed substitute claims for failing to meet the subject matter eligibility requirements of § 101. Uniloc 2017 LLC v. Hulu, LLC, Case No. 19-1686 (Fed. Cir. July 22, 2020) (Wallach, J.) (Dyk, J., dissenting).

Hulu filed an IPR petition challenging claims of Uniloc’s patent directed to adjustable software licensing for digital products. After the PTAB instituted review, Uniloc filed a motion for substitute claims, conditional on whether the PTAB found the original claims unpatentable. Before the PTAB issued its final determination and before it ruled on the motion for substitute claims, a district court, in a related proceeding, held Uniloc’s asserted claims invalid as directed to patent-ineligible subject matter. Shortly thereafter, the PTAB issued a final written decision finding the challenged claims unpatentable over the prior art, and it found the substitute claims unpatentable under § 101. Uniloc appealed the PTAB’s use of § 101 to invalidate its substitute claims.

While Uniloc’s appeal of the Hulu IPR was pending, the Federal Circuit affirmed the district court’s invalidity finding as to the original claims. With respect to the Hulu appeal, the Federal Circuit ordered the parties to address whether the appeal was moot in view of the ultimate finality with respect to invalidity of the original claims, thereby divesting the PTAB of jurisdiction over the IPR.

The majority held that the finality of the district court’s invalidity finding did not necessarily divest the PTAB of authority to consider substitute claims. It determined that the mootness issue was waivable, and that Hulu had waived the argument because it failed to raise mootness during the pendency of the IPR at the time the district court issued its decision. Even if Hulu had not waived the argument, the majority found that the PTAB’s authority to consider substitute claims does not depend on any live dispute about the original claims, as long as the motion to amend in the IPR was timely filed.

As to the PTAB’s rejection of the claims under § 101, the majority held that although the PTAB is restrained in an IPR proceeding to invalidating a patent’s original claims only under the anticipation and obviousness grounds raised in the petition, the PTAB may use other invalidity tools as a “new ground of rejection” for substitute claims, including for lack of patentable subject matter under § 101. The majority also suggested that other grounds of patentability would be within the scope of the PTAB’s authority, including rejections under the various subsections of § 112. The majority was concerned that limiting the PTAB’s review might force it to issue substitute claims that fail to meet all the statutory [...]
