Unclean Hands Aren’t Just for Toddlers

by Jacob Michael Bass | Apr 25, 2024 | Patents

In an action involving manufacturers of a self-sealing dining mat for toddlers, the US Court of Appeals for the Federal Circuit affirmed a district court’s finding that the defendants were barred from obtaining relief on their counterclaims under the unclean hands doctrine, thereby vacating the district court’s other findings on inequitable conduct, obviousness, attorneys’ fees and costs. Luv N’ Care, Ltd. et al. v. Laurain et al., Case No. 22-1905 (Fed. Cir. Apr. 12, 2024) (Reyna, Hughes, Stark, JJ.)

Luv N’ Care and Nouri E. Hakim (collectively, LNC) filed suit against Lindsey Laurain and Eazy-PZ (EZPZ), asserting various claims for unfair competition under the Lanham Act and Louisiana law. LNC also sought declaratory judgment that EZPZ’s design patent was invalid, unenforceable and not infringed. After the suit was filed, the US Patent & Trademark Office (PTO) issued Laurain a utility patent directed toward self-sealing dining mats. Laurain subsequently assigned her rights to EZPZ, which then asserted counterclaims for utility patent, design patent and trademark infringement.

Following discovery, the district court granted LNC’s motion for summary judgment, finding all claims of EZPZ’s utility patent as obvious in view of three prior art references. EZPZ moved for reconsideration, which the district court denied, indicating that a “ruling providing further reasoning will follow in due course.” Before any such ruling issued, the PTO issued an ex parte reexamination certificate confirming the patentability of the utility patent claims two days before the district court’s bench trial began.

EZPZ did not provide this reexam certificate to the district court prior to the bench trial. During the bench trial, the district court found that EZPZ had not committed inequitable conduct but that EZPZ’s litigation conduct constituted unclean hands. After the district court entered judgment, EZPZ moved for reconsideration of summary judgment based on the ex parte reexamination certificate. The district court denied this motion and found that the evidence did not compel alteration of the prior ruling that the utility patent was invalid. It also denied LNC’s motion for attorneys’ fees and costs. EZPZ appealed.

The Federal Circuit affirmed the unclean hands determination but vacated the district court’s rulings on inequitable conduct, invalidity, attorneys’ fees and costs. As to unclean hands, the Court reasoned that EZPZ failed to disclose patent applications related to the utility patent until well after the close of discovery and dispositive motion practice. EZPZ also blocked LNC’s efforts to discover Laurain’s prior art searches by falsely claiming that she had conducted no such searches and that all responsive documents had been produced. It further found that EZPZ witnesses, including Laurain and EZPZ’s former outside counsel, repeatedly gave evasive testimony during depositions and at trial. The Court affirmed the district court’s determination that EZPZ’s misconduct bore an immediate and necessary connection to EZPZ’s claims for infringement because the undisclosed material was directly relevant to the development of LNC’s litigation strategy and undermined LNC’s ability to press its invalidity and unenforceability challenges. The Court found no clear error in the district court’s reasoning that [...]

The End Is Not So Near: Patent Term Adjustments Count in Obviousness-Type Double Patenting Determinations

by Jake B. Vallen | Sep 7, 2023 | Patents

Addressing for the first time how patent term adjustments (PTAs) interact with obviousness-type double patenting (ODP), the US Court of Appeals for the Federal Circuit concluded that when members of a patent family have different expiration dates due to PTAs, the earlier expiring family members can be used as a basis for an ODP invalidity challenge against the later expiring family members. In re Cellect, LLC, Case Nos. 2022-1293; -1294; -1295; -1296 (Fed. Cir. Aug. 28, 2023) (Lourie, Dyk, Reyna, JJ.)

Cellect owns several patents directed to devices with image sensors, such as personal digital assistant devices and phones. Each patent claims priority from a single application. None of the patents were subject to a terminal disclaimer, and each was granted PTA under 35 U.S.C. § 154(b) because of PTO delay during prosecution. Had the patents not been granted PTA, each one would have expired on the same date as the original application.

After Cellect sued for infringement, the defendant requested ex parte reexaminations and asserted that the patents were unpatentable based on ODP. During the reexaminations, the Examiner “determin[ed] that the challenged claims were obvious variants of Cellect’s prior-expiring reference patent claims” because “although the ODP invalidating reference patents form a network across the four ex parte reexamination proceedings, all invalidated claims can be traced back to the single family member [now expired] patent that did not receive a grant of PTA.” The Patent Trial & Appeal Board affirmed the Examiner’s finding. Cellect appealed.

The Federal Circuit began with the inquiry for determining unpatentability based on ODP and whether, in that context, a patent’s expiration date includes a duly granted PTA under 35 U.S.C. § 154. While the Court recognized that the relevant expiration date for an ODP analysis where a patent received a patent term extension (PTE) is the pre-PTE expiration date, the Court concluded that, in the context of patents that have received PTAs, the relevant expiration date for analyzing ODP is the expiration date accounting for the PTA regardless of whether a terminal disclaimer has been filed. The Court reasoned that when determining whether claims are unpatentable for ODP, PTA and PTE, they “should be treated differently” because each is governed by different statutes that were designed to address different circumstances. While both PTAs and PTEs were intended to recover lost patent terms, PTAs were designed to extend patent terms because of administrative delays in patent processing and preclude the extension of a patent term past a terminal disclaimer. PTEs were designed to extend a patent term because of regulatory delays in product approval and are not foreclosed by a terminal disclaimer. As such, the Court reasoned that not contemplating a PTA when analyzing ODP would “frustrate the clear intent of Congress” because “when a terminal disclaimer has been entered in a patent subject to PTA, no patent (or claim) may be extended beyond the disclaimed expiration date.”

The Federal Circuit next considered whether examiners are required to consider “equitable concerns” such as good faith when [...]

Common Sense: Nonparties Not Precluded by Ex Parte Reexamination Termination

by Brennen Baylor | Jun 8, 2023 | Trademarks

In a precedential decision, the US Patent & Trademark Office (PTO) Trademark Trial & Appeal Board denied a motion for judgment based on either claim or issue preclusion, and in the alternative for a show cause order, in a challenger’s petition. Common Sense Press Inc. d/b/a Pocket Jacks Comics v. Ethan Van Sciver and Antonio J. Malpica, Cancellation No. 92075375, 2023 BL 171365 (TTAB May 19, 2023) (Wellington, Pologeorgis, English, ATJs).

Common Sense Press filed a petition to cancel the registration for the mark “Comics Gate” for comics. In its petition, Common Sense asserted claims of nonuse, abandonment and fraud. The Respondents denied the allegations in the petition and also raised unclean hands by petitioner as a defense.

Common Sense also requested reexamination of the “Comics Gate” mark, which the PTO Director instituted on May 9, 2022. The cancellation proceeding was suspended pending the outcome of the reexamination. The Respondents were instructed to submit evidence to establish use of their mark for comics as of the August 13, 2020, deadline for filing a statement of use, as required under Section 1(d) of the Lanham Act.

The Respondents’ Section 1(d) statement showed that the “Comics Gate” mark was used in connection with comics sales in interest commerce and that such comics were provided via interest trade channels during the relevant period. In view of the Respondents’ evidence, the PTO Director determined that use had been demonstrated for comics and terminated the reexamination.

With the Notice of Termination in hand, the Respondents requested that the Board enter judgment in their favor in the cancelation proceeding as to nonuse and abandonment based on issue preclusion or, in the alternative, issue a show cause order to Common Sense as to why judgment should not be entered against them.

The Board denied the Respondents’ request, reasoning that termination of a reexamination proceeding does not preclude future nonuse challenges. Nor does such a reexamination termination decision have preclusive effect on a petitioner seeking cancellation, even if the petitioner requested the terminated reexamination. Citing due process concerns, the Board explained that the termination of an ex parte reexamination proceeding in which the petitioner necessarily does not participate may not serve as a basis for preventing the petitioner from raising even identical challenges in another action. The Board further noted that while the applicable statute “contains explicit estoppel provisions that bar the filing of future expungement or reexamination proceedings as to the identical goods or services once a proceeding of the same kind has been instituted . . . neither the statute nor regulations set forth a limitation on any party’s ability to petition to cancel a registration just because it is or has been the subject of a reexamination or expungement proceeding.” Thus, the Board concluded there is no basis to issue a show-cause order to a litigant who never appeared in a prior action.

Practice Note: This case serves as a reminder of the metes and bounds of an ex parte reexamination or expungement proceeding. Although [...]

What Preclusion? Post-IPR Reexam Moves Forward

by Tim Dunker | Mar 10, 2022 | Patents

The US Court of Appeals for the Federal Circuit revived a petitioner’s validity challenge seeking ex parte review at the US Patent & Trademark Office (PTO), reversing a district court decision dismissing its complaint seeking Administrative Procedures Act (APA) review of the PTO Director’s vacatur decision. The Federal Circuit concluded that the petitioner was not subject to inter partes review (IPR) estoppel from pursuing reexamination after receiving IPR final written decisions concerning the same claims of the same patents. Alarm.com Inc. v. Hirshfeld, Case No. 21-2102 (Fed Cir, Feb 24, 2022) (Taranto, Chen, Cunningham, JJ.)

This case explores the tension between the ex parte reexam statute and the IPR estoppel statute. Under 35 U.S.C. § 302, “any person at any time may file a request for reexamination . . . of any claim of a patent on the basis of any prior art cited under [§ 301].” If the PTO Director determines “pursuant to [§ 303(a)] that no substantial new question of patentability is raised,” that determination “will be final and nonappealable.” § 303(c). If a substantial new question is deemed to have been raised, “the determination will include an order for reexamination of the patent for resolution of the question.” § 304. Under § 315(e)(1), a petitioner in an IPR that results in a final written decision is estopped from requesting or maintaining a proceeding before the PTO “with respect to that claim on any ground that the petitioner raised or reasonably could have raised during that inter partes review.”

Alarm.com filed several IPR petitions that resulted in three final written decisions holding that Alarm.com had not carried its burden of proving that the challenged claims at issue were unpatentable. The Federal Circuit affirmed all three decisions in its 2018 ruling in Vivint, Inc. v. Alarm.com. Alarm.com subsequently filed three requests for ex parte reexamination of the same claims under 35 U.S.C. § 302 and 37 C.F.R. § 1.510, presenting different grounds than were presented in the IPRs. Instead of rendering a § 303(a) decision on the issue of whether petitioner presented a substantial new questions of patentability, the Director vacated the requests, finding that Alarm.com reasonably could have raised its reexamination grounds in the IPRs and, therefore, was estopped under § 315(e)(1) from submitting the requests. Alarm.com filed a complaint in the Eastern District of Virginia against the Director and the PTO under 5 U.S.C. § 702, stating that the Director’s actions were arbitrary and capricious. Following dismissal of the complaint, Alarm.com appealed.

The PTO argued that the overall ex parte reexamination scheme precluded judicial review of the Director’s vacatur decision based on § 315(e)(1) estoppel, which brought Alarm.com’s challenge within the exception to APA review, i.e., where “statutes preclude judicial review.” 5 U.S.C. § 701(a)(1). The PTO did not raise any other arguments as to why judicial review would not be available under the APA.

The Federal Circuit explained that “[t]he only portion of the ex parte reexamination statutory scheme that expressly precludes judicial review is § [...]

Ex Parte Reexamination Not Allowed After Failed IPR Challenge

by Paul Devinsky | Oct 14, 2021 | Patents

The US Court of Appeals for the Federal Circuit found that ex parte reexamination was unavailable to a challenger who repeatedly tried and failed to raise the same arguments for the same patent in a prior inter partes review (IPR) proceeding. In re: Vivint, Inc., Case No. 20-1992 (Fed. Cir. Sept. 29, 2021) (Moore, C.J.)

Vivint sued Alarm.com in 2015 for infringement of several patents. In response, Alarm requested that the Patent Trial & Appeal Board (PTAB) institute “a litany of post-issuance review proceedings,” including three separate IPR petitions directed to one of the patents. The PTAB refused to institute two of the petitions because Alarm failed show to a reasonable likelihood that it would prevail on at least one challenged claim and also refused to institute the third petition because it represented an example of “undesirable, incremental petitioning.” According to the PTAB, Alarm had “used prior Board decisions as a roadmap to correct past deficiencies” and allowing such “similar, serial challenges to the same patent” by the same challenger risked, not only harassment of patent owners, but also frustration of congressional intent behind the America Invents Act (AIA).

More than a year later, Alarm filed a request for ex parte reexamination of the patent—a request that used repackaged versions of arguments from its unsuccessful IPR petition. Despite the striking similarity between Alarm’s prior and current arguments, including two out of the four original IPR patentability questions being copied verbatim from the failed petition into the ex parte reexamination request, the PTAB found the petition raised substantial new questions of patentability and ordered reexamination. Vivint responded by seeking dismissal of the ex parte reexamination under 37 C.F.R. § 1.181, arguing that the PTAB has the authority under 35 U.S.C § 325(d) to deny the ex parte reexamination request because that statute applies to ex parte reexaminations and IPRs with “equal force.” The PTAB rejected Vivint’s request, stating that any § 1.181 petition raising a § 325(d) challenge must be filed before reexamination is ordered.

Vivint filed a second § 1.181 petition seeking reconsideration of the § 325(d) issue, arguing that it would have been impossible for Vivint to file the § 1.181 petition before ex parte reexamination was ordered. Vivint also argued that even if the PTAB lacked general authority to terminate the reexamination, it could exercise such authority under the Administrative Procedure Act (APA). Vivint also asserted that the PTAB “acted arbitrarily and capriciously by applying the same law to the same facts and reaching a different conclusion.” The PTAB rejected Vivint’s arguments and denied its second petition, finding that Vivint could have sought a waiver of the rules having to do with the required prior-to-ex parte timing of a § 1.181 petition vis-à-vis institution of ex parte reexamination. The PTAB also noted that ex parte reexamination was not inconsistent with denying the initial IPR. Ultimately, after an examiner issued a final rejection for all claims of the patent, Vivint appealed to the PTAB. The PTAB affirmed and Vivint [...]
