Sins of the Fathers? Grandparent IPR Factors into Current Institution Decision

by Kyle Sorenson, PhD | Sep 7, 2023 | America Invents Act, Patents

US Patent & Trademark Office (PTO) Director Kathi Vidal vacated and remanded a Patent Trial & Appeal Board decision denying institution of an inter partes review (IPR) because the Board improperly applied the precedential Advanced Bionics framework in rendering its decision. Keysight Tech., Inc. v. Centripetal Networks, Inc., IPR2022-01421 (PTAB Decision Review Aug. 24, 2023) (Vidal, Dir.)

Keysight Tech. petitioned for an IPR proceeding against a patent owned by Centripetal Networks, challenging the validity of all claims. After the Board denied institution, Director Vidal issued a sua sponte director review decision, vacating and remanding the Board’s decision.

The Centripetal patent is the great-grandchild of, and shares the same disclosure as, an earlier Centripetal patent that was subject to an IPR proceeding during the pendency of the presently challenged patent. The Final Written Decision (FWD) in the earlier IPR found all claims of the patent unpatentable. The patent owner included that FWD in an Information Disclosure Statement (IDS) submitted during the prosecution of the presently challenged patent, and the examiner initialed it as having been considered.

In its decision denying institution, the Board cited the guidance of Advanced Bionics, which articulates a framework that requires that the Board determine the following:

Whether the same or substantially the same prior art or arguments made in the petition were previously presented to the PTO during prosecution of the challenged patent
Whether the PTO erred in a manner material to the patentability of the challenged claims when it allowed the claims of the patent.

If both factors are met in the affirmative, the Board should not exercise its discretion to deny institution.

Here, the Board found that the first factor of the Advanced Bionics framework was met because the petitioner’s arguments in its petition were the same or substantially the same as those in the FWD in the IPR of the grandparent patent. However, the Board found that the second part of the framework was not satisfied and therefore denied institution.

Although Director Vidal agreed with the Board’s findings under the first factor, she vacated the Board’s findings pursuant to the second factor after determining that this factor was also met. Director Vidal found that the PTO erred in a manner material to the patentability of the challenged claims for the following reasons:

The challenged patent and the grandparent were directed to the same subject matter.
The prior art references submitted to the PTO during the prosecution of the challenged patent were the same as those asserted in earlier IPR and were considered by the examiner through the patent owner’s IDS.
In the grandparent IPR, the Board held all of the claims of the patent unpatentable due to these same prior art references.
The examiner’s statement of reasons for allowing the challenged patent was that the claims were directed to limitations that appeared in both the currently challenged claims and the claims found unpatentable in the grandparent patent.

As the director noted, the overlap between the claim limitations in the [...]

Nothing Lost in Translation: Book’s Spanish Version Isn’t Different Creative Work

by Dana Breitman | Aug 31, 2023 | Trademarks

In a precedential opinion, the Trademark Trial & Appeal Board of the US Patent & Trademark Office upheld an examiner’s refusal to register a trademark on the ground that the proposed mark was the title of a single creative work and therefore did not function as a trademark. In re Douglas Wood, Serial No. 88388841 (TTAB, Aug. 15, 2023) (Adlin, Larkin, English, ATJs).

Douglas Wood sought to register the standard-character mark CHURCH BOY TO MILLIONAIRE for goods ultimately identified as “Books in the field of faith-based coaching, personal development, motivational and inspirational topics; books in the nature of memoirs; books about personal development; printed matter in the field of personal development, namely, books, booklets, curricula, newsletters, magazines, printed periodicals.” Since the title of a single book cannot be registered as a trademark, in support of the application Wood stated that the proposed mark was used on two separate books, an English-language book titled Church Boy to Millionaire and a Spanish-language book titled De Chico de Iglesia a Millonario. According to Wood, he published two books of different titles that had been marketed under the same mark as evidenced by use on his website.

The examining attorney refused registration, finding that the mark was the title of a single creative work and thus did not function as a trademark. Wood appealed.

The Board determined that Church Boy to Millionaire was the title of a single work, and that the book’s Spanish translation did not qualify as a separate work that might create a “series” entitled to trademark protection. The Board explained that “[t]he title of a single creative work, such as a book, is not considered to be a trademark, and is therefore unregistrable.” The Board further differentiated trademarks from copyrights, explaining that “[u]nlike a copyright that has a limited term, a trademark can endure for as long as the trademark is used. Therefore, once copyright protection ends, and the work falls in the public domain, others must have the right to call the work by its name.”

Wood argued that Church Boy to Millionaire and its Spanish translation, De Chico de Iglesia a Millonario, were different works since the choice of the translator had a large impact on the version created. The Board explained that the issue was whether the content “has change[d] significantly” in translation. The Board acknowledged that translators can employ their unique skills and cultural understandings to produce different content for a book in another language. However, the examining attorney showed that Wood did not provide any evidence that the Spanish version had content that significantly differed from the English version. On the contrary, the evidence of use contradicted Wood’s position that the Spanish translation featured different content because his website’s links directed customers to “get the book today” and “get the book in Spanish,” which effectively confirmed that [...]

Tune to the Right Channel: Disclosure Lacking Fraud Information Isn’t an FCA Qui Tam Bar

by Cecilia Choy, Ph.D. | Aug 17, 2023 | Patents

The US Court of Appeals for the Ninth Circuit reversed a district court’s decision to dismiss a qui tam action brought under the False Claims Act (FCA) after analyzing the public disclosure bar channels. The case required the Ninth Circuit to examine Congress’s 2010 amendments to the FCA public disclosure bar to determine whether the claims were substantially the same as information publicly disclosed in any one of three enumerated channels. Silbersher v. Valeant Pharm. Int’l, Inc., No. 20-16176 (9th Cir. Aug. 3, 2023) (Schroeder, Sanchez, Antoon, JJ.)

The FCA imposes civil liability on anyone who knowingly presents a fraudulent claim for payment to the federal government. The FCA includes a qui tam provision that allows private citizens (or “relators”) to bring fraud claims on behalf of the government. In 2010, Congress’s public disclosure bar precluded qui tam actions if substantially the same allegations or transactions were publicly disclosed in one of three channels:

In a federal criminal, civil or administrative hearing in which the government or its agent is a party
In a congressional, Government Accountability Office (GAO) or other Federal Report hearing, audit or investigation
From the news media, unless the action is brought by the Attorney General or the person bringing the action is an original source of the information.

Valeant owns the “Otterbeck patents” for its drug Apriso’s delayed-release formula. Valeant initiated an infringement action against Lupin, a generic drug manufacturer that attested in an abbreviated new drug application (ANDA) that the Otterbeck patents were invalid because of prior art that described a similar delayed-release formula. Thereafter, Valeant extended its monopoly by applying for and being granted a new patent that claimed a recent discovery that Apriso was effective when taken without food. GeneriCo then challenged the new patent in an inter partes review (IPR) proceeding, arguing that it was obvious that Apriso would be effective without food. GeneriCo presented two medical studies as support. The Patent Trial & Appeal Board agreed and invalidated the claims in the new patent.

Zachary Silbersher, GeneriCo’s IPR lawyer and a relator in another FCA suit in the same court, discovered that Valeant failed to disclose certain information to the US Patent &Trademark Office (PTO) during the IPR proceeding. Specifically, he discovered that three years before applying for the new patent, Valeant applied for another patent where it claimed it made an unexpected finding that taking Apriso’s active ingredient with food made the drug more effective. This claim was the opposite of the claim made in the new application that had been invalidated in the IPR proceeding.

Silbersher brought an FCA case seeking damages from Valeant, alleging that Valeant fraudulently obtained the Otterbeck and new patent to prolong its monopoly and charge an artificially high price for Apriso. The district court dismissed Silbersher’s qui tam action as precluded by the public disclosure bar because the IPR qualified as an “other Federal hearing” under channel two of the bar, as described above. Silbersher appealed.

The Ninth Circuit analyzed whether [...]

Remedies as Big as Your Bamba

by Thomas DaMario | Aug 10, 2023 | Trademarks

Following the district court’s finding of trademark infringement on summary judgment, the US Court of Appeals for the Sixth Circuit affirmed the district court’s subsequent award of profits, costs and attorneys’ fees in favor of the trademark holder. La Bamba Licensing, LLC v. La Bamba Authentic Mexican Cuisine, Inc., nka La Villa Rica Mexican Cuisine, Inc., Case No. 22-5853 (Gilman, Larsen, Nalbandian, JJ.)

La Bamba Licensing operates a series of Mexican restaurants in the Midwest under the name “La Bamba.” It obtained various federal trademark registrations in 1998. Almost 20 years later, La Bamba Authentic Mexican Cuisine (now known as La Villa Rica) opened a Mexican restaurant under the name “La Bamba Authentic Mexican Cuisine” with a single location in Lebanon, Kentucky. Shortly after learning of the La Villa Rica restaurant, La Bamba Licensing sent a cease-and-desist letter to La Villa Rica demanding that La Villa Rica cease use of the LA BAMBA mark. La Villa Rica responded but refused to alter its conduct because it did “not see any basis for [La Bamba Licensing’s] demands.” Three months after sending the cease-and-desist letter, La Bamba Licensing filed suit in the Western District of Kentucky alleging trademark infringement and unfair competition. More than one year later, La Villa Rica changed the name of its restaurant to “La Villa Rica Authentic Mexican Cuisine, Inc.”

The district court ultimately granted summary judgment in favor of La Bamba Licensing on all pending claims and permanently enjoined La Villa Rica from using the LA BAMBA mark. La Bamba Licensing subsequently filed a motion seeking profits, costs associated with bringing the action and attorneys’ fees. Following an evidentiary hearing, the district court granted La Bamba Licensing’s motion and awarded all three forms of relief. La Villa Rica appealed the district court’s decision to award profits and attorneys’ fees but did not appeal the award of costs or the district court’s calculation of either profits or attorneys’ fees.

The Sixth Circuit started its analysis of the profits award by identifying the factors courts should consider, including the defendant’s intent to deceive, whether sales were diverted, the adequacy of other remedies, any unreasonable delay by the plaintiff in asserting its rights, public interest in making the misconduct unprofitable and “palming off” (i.e., whether the defendant used its infringement of the plaintiff’s mark to sell its own products to the public through misrepresentation). The Sixth Circuit noted that the district court relied on two factors—the defendant’s intent and public interest in making the misconduct unprofitable—plus the defendant’s “willfulness” in determining that an award of profits was appropriate. The Sixth Circuit credited the district court’s reasoning, noting that “[e]ven after La Villa Rica received a cease-and-desist letter containing notice of La Bamba’s registered mark, and ‘in the face of [its] attorney’s advice that [it] might have a problem,’ La Villa Rica continued to use the LA BAMBA mark for a year and a half and ‘offered no legally sufficient explanation or support for its actions.’”

La Villa Rica argued that [...]

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

by Benjamin Ediger, Ph.D. | Aug 10, 2023 | Trademarks

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 [...]

RIP for POP: PTO Updates Interim Director Review Procedures

by Amol Parikh | Aug 3, 2023 | Uncategorized

On July 24, 2023, the US Patent & Trademark Office (PTO) announced that a revised interim Director Review (DR) process and Appeals Review Panel (ARP) process will replace the Precedential Opinion Panel Process. Updates to the interim DR process include the following:

Expanding the process to permit parties to request DR of Patent Trial & Appeal Board decisions on institution in America Invents Act (AIA) proceedings
Providing updated guidance as to what types of issues the Director will consider in DR, as well as additional guidance on several topics, such as the initiation of DR at the sole discretion of the Director (sua sponte DR), remands to Board for further proceedings and the Director’s sanction authority
Providing the Director with the option to delegate review to a new independent panel called the Delegated Rehearing Panel (DRP)
Creating a new ARP, which may be convened by the Director sua sponte to review Board ex parte, reexamination or reissue appeal decisions.

Under the interim DR process, a party to a Board decision may now request DR of a Board decision, whether to institute trial, a final written decision or a decision granting a request for rehearing.

After a DR request is received and processed, the request will then be routed to an Advisory Committee that the Director has established to assist with the process. The Advisory Committee comprises 11 members and includes representatives from various PTO business units who serve at the discretion of the Director. A quorum of seven members is needed for the committee to meet. The Advisory Committee may include members from the following business units:

Office of the Under Secretary (not including the Director or Deputy Director)
The Board (not including members of the panel for each case under review)
Office of the Commissioner for Patents (not including the Commissioner for Patents or any persons involved in the examination of the challenged patent)
Office of the General Counsel
Office of Policy and International Affairs.

The Director will review each request for DR; the underlying decision, including the associated arguments and evidence; and the recommendation of the Advisory Committee. The Director will then determine whether to grant or deny review or delegate a decision to a Delegated Rehearing Panel (DRP). The DRP will be selected from among the Chief Judge, Deputy Chief Judge, Vice Chief Judges and Senior Lead Judges of the Board, excluding judges who served on the original panel for the case under review or otherwise have a conflict with the case. An appellant can request a rehearing of a DRP decision or appeal the decision to the US Court of Appeals for the Federal Circuit.

An ARP that consists of the Director, the Commissioner for Patents and the Chief Judge of the Board has now been created. The panel may be convened by the Director sua sponte to review ex parte, reexamination or reissue appeal decisions. Requests for ARP review will not be considered. ARP decisions are appealable to the Federal Circuit. An appellant may not [...]

No Need for Unnecessary RPI Determinations

by Joshua Revilla | Jul 27, 2023 | Patents

The US Patent & Trademark Office Director partially vacated the Patent Trial & Appeal Board’s real-party-in-interest (RPI) determination because that determination was not necessary to resolve the underlying proceeding. Unified Patents, LLC v. MemoryWeb, LLC, IPR2021-01413, Paper 76 (PTAB May 22, 2023) (Vidal, Dir.)

Unified Patents filed a petition requesting inter partes review (IPR) of a patent owned by MemoryWeb. In its petition, Unified certified that it was the only RPI. Prior to institution, both parties briefed whether Unified should have identified two third parties as RPIs under 35 U.S.C. § 312(a)(2). In its institution decision, the Board declined to determine whether the third parties were RPIs because there was no allegation in the proceeding of a time bar or estoppel based on there being an unnamed RPI, and therefore the proceedings would not have created a time bar or estoppel under 35 U.S.C. § 315 even if the third parties were included as RPIs.

After institution, MemoryWeb continued to argue that the Board should terminate the proceeding because of Unified’s alleged failure to name the third parties as RPIs while also arguing that in the alternative, the Board should find the two third parties estopped from challenging the validity of the claims at issue in two different IPRs covering the same patent. The Board then issued an order identifying the third parties as RPIs, explaining that it was now appropriate to determine whether the two third parties were RPIs “[b]ecause the issue of Section 315(e) estoppel has been put before us [as relevant to the subsequent IPR challenges filed by the third parties], and we now have a complete factual record available to fully address the RPI question, and to avoid unnecessary prejudice to Patent Owner.” The Board also explained that it was now necessary to determine whether the third parties were RPIs in the case at hand to determine whether they would be estopped in a subsequent proceeding.

Unified filed a request for Director review of the Board’s RPI determination. Unified argued that the panel erred by issuing a non-binding advisory opinion on RPI that prejudiced the third parties by prejudging the RPI issue without their participation and where the decision could bind them in their later-filed proceedings. Unified also cited the Board’s precedential decision in SharkNinja v. iRobot, arguing that the Board should not resolve an RPI issue when it would not create a time bar or estoppel under 35 U.S.C. § 315 in the proceeding.

The Director concluded that the Board can and should determine the RPIs or real parties in privity in a proceeding where that determination may impact the underlying proceeding, including (but not limited to) a time bar under 35 U.S.C. § 315(b) or estoppel under 35 U.S.C. § 315(e) that might apply. However, the Director determined that such was not the situation here since determining the RPI issue was not necessary to resolve the proceeding. The Director, therefore, vacated the Board’s RPI determinations.

No Snipe Hunting: AIA Adherence Means No Interference (Proceedings)

by Jake B. Vallen | Jul 27, 2023 | America Invents Act, Patents

The US Court of Appeals for the Federal Circuit concluded that patents and applications that have only ever contained claims with an effective filing date after March 16, 2013—i.e., pure America Invents Act (AIA) patents—may not be subjected to an interference proceeding by the US Patent & Trademark Office (PTO) Director. SNIPR Techs. Ltd. v. Rockefeller Univ., Case No. 2022-1260 (Fed. Cir. July 14, 2023) (Chen, Wallach, Hughes, JJ.)

SNIPR Technologies owns a family of five patents directed to methods of selectively killing bacteria using clustered regulatory interspaced short palindromic repeats (CRISPR) gene editing. SNIPR was involved in an interference proceeding with Rockefeller University, which filed a patent application for technology also directed to selectively killing bacteria. The SNIPR patents claimed priority to a Patent Cooperation Treaty application filed on May 3, 2016, thus placing the SNIPR patents squarely within the scope of the AIA. The Rockefeller application claimed priority to, among other things, a US provisional application filed on February 7, 2013, making the Rockefeller application a pure pre-AIA application. The Patent Trial & Appeal Board initially declared an interference between claims 20 to 33 of the Rockefeller application and all claims of the SNIPR patents. The Board ultimately identified Rockefeller as the senior party and canceled all of SNIPR’s claims. SNIPR appealed.

The issue before the Federal Circuit was whether the Board had the authority to cancel SNIPR’s pure AIA claims for lack of invention priority under pre-AIA § 102(g), and more broadly, whether pure AIA patents may, as a matter of law, be part of an interference proceeding.

First, the Federal Circuit examined the plain language of AIA § 3(n) and the statutory purpose and history of the AIA. The Court reasoned that “AIA § 3(n) makes clear that [unless Congress provides otherwise,] only pure pre-AIA and mixed patents may be part of an interference.” As the Court stated, AIA § 3(n)(1) does not permit the AIA’s amendments to apply retroactively and the AIA repealed the statutory grant of power to hear interferences (pre-AIA § 135), instead providing for derivation proceedings.

Next, the Federal Circuit addressed Rockefeller’s and the Director’s arguments that the statutory language of pre-AIA § 135(a) authorizes the Director to declare an interference for “any unexpired patent”—including unexpired pure AIA patents. Unpersuaded, the Court concluded that pre-AIA § 135(a), read in conjunction with the AIA, excludes pure AIA patents for the following reasons:

The AIA replaced interference proceedings with derivation proceedings.
The AIA deleted all other references to interferences.
The AIA repealed the first-to-invent system of patentability, rendering interference proceedings superfluous.
Permitting interferences for pure AIA patents would subject AIA patents to interferences “for over twenty years after the AIA’s effective date,” which would be contrary to the purpose of the AIA—to implement the first-to-file system of patentability.

Moreover, such a statutory construction would belie AIA § 3(n)(2), which expressly allows for interferences for mixed patents (i.e., patents and applications that contain, or contained at any time, at least one claim with [...]

Speculative Injury from Rulemaking Petition Denial Doesn’t Confer Standing

by Cecilia Choy, Ph.D. and Hannah Hurley | Jul 20, 2023 | America Invents Act, Patents

The US District Court for the District of Columbia affirmed the dismissal of a case alleging that the US Patent & Trademark Office (PTO) violated the Administrative Procedure Act (APA) by denying the plaintiffs’ rulemaking petition. The district court found that the plaintiffs’ alleged injury was too speculative to confer Article III standing. US Inventor, Inc. v. US Patent and Trademark Office, Case No. 22-2218 (D.D.C. July 12, 2023) (Bates, J.)

Under the America Invents Act (AIA), the Patent Trial & Appeal Board may hear challenges to the validity of patents through inter partes review (IPR) and post-grant review (PGR). The decision to initiate a review is made at the discretion of the PTO on a case-by-case basis. US Inventor, Inc., and National Small Business United (collectively, NSBU) filed a rulemaking petition with the PTO, arguing that the PTO unlawfully designated cases as precedential or informative without putting those considerations through notice-and-comment rulemaking, as required by the APA. NSBU expressed the same position in a previous lawsuit filed in the Eastern District of Texas that was dismissed for lack of standing—a decision upheld by the US Court of Appeals for the Fifth Circuit. NSBU subsequently filed a lawsuit in the District of Columbia. The PTO filed a motion to dismiss for lack of standing.

In a motion to dismiss, a court will accept facts alleged in the complaint as true but will not assume the truth of legal conclusions. The District of Columbia noted that not every denial of a rulemaking petition confers standing on the petitioner. Standing is established by claiming an injury in fact that can be traced to the defendant’s actions and is likely to be redressed by the court. Therefore, a plaintiff must show that the denial of the petition caused a concrete injury in fact. Injury in fact must be concrete, particularized and not conjectural or hypothetical. Standing can be established via associational standing or organizational standing. Here, the court found that NSBU could establish neither.

In finding no associational standing, the District of Columbia agreed with the PTO that NSBU’s theory of injury was too speculative and not concrete. NSBU proposed an “uncertain series of events” that could lead to an alleged injury, but the court rejected the claim as attenuated conjecture based on the actions of independent third parties (similar to the fact pattern in the Supreme Court’s 2013 decision in Clapper v. Amnesty Int’l USA.)

The District of Columbia heavily criticized the first step of NSBU’s proposed series of events, which was that a valid IPR or PGR would have to be filed on behalf of a patent held by a member of NSBU’s organizations. The court found that identifying potential members that might face IPR or PGR proceedings if a third party decided to bring a claim against them was too hypothetical and relied entirely on the actions of a third party.

The District of Columbia also disagreed with NSBU’s reliance on statistics. NSBU argued that patent cancellation is more likely [...]

If at First You DuPont Succeed, Try a Different Factor

by Mike Baldwin | Jul 13, 2023 | Trademarks

The US Court of Appeals for the Federal Circuit remanded a Trademark Trial & Appeal Board decision, finding that the Board incorrectly analyzed several DuPont factors, improperly disregarded the DuPont factor regarding third-party registration on similar goods, permitted the opposer to succeed without a showing of identical marks for identical goods used in the marketplace and predicated its comparative analysis on the incorrect mark. Spireon, Inc. v. Flex Ltd., Case No. 22-1578 (Fed. Cir. June 26, 2023) (Mayer, Reyna, Dyk, JJ.)

Spireon filed a trademark application for the mark FL FLEX for use in connection with “[e]lectronic devices for tracking the locations of mobile assets in the nature of trailers, cargo containers, and transportation equipment using global positioning systems and cellular communication networks.” After the Examining Attorney approved the application, Flex opposed registration on grounds of priority and likelihood of confusion with Flex’s previously registered marks: FLEX, FLEX (stylized) and FLEX PULSE.

The Board sustained Flex’s opposition based on its analysis of the DuPont factors for evaluating likelihood of confusion. There are a total of 13 factors that together form the underlying factual findings upon which the legal conclusion of likelihood of confusion is made. Not all factors are relevant in every case.

In its consideration of the first DuPont factor (the similarity of the marks), the Board addressed the strength of Flex’s marks, including the marks’ conceptual and commercial strength. The Board weighed five marks—FLEX (in three relevant commercial contexts), LOAD FLEX VALUE FLEX—and concluded that the third-party evidence did not show that Flex’s marks were either conceptually weak or inherently distinctive. The Board then considered the similarity of the marks, analyzing Spireon’s FL FLEX against FLEX, FLEX (stylized) and FLEX PLUS (rather than the actual mark FLEX PULSE). The Board found the marks highly similar and concluded that the first DuPont factor supported a finding of likelihood of confusion. The Board also addressed three other DuPont factors that it considered relevant, but no others. Spireon appealed.

The Federal Circuit reversed. The Court found that the Board erred in not considering the sixth DuPont factor, “[t]he number and nature of similar marks in use on similar goods.” This factor requires an evaluation of conceptual strength and commercial strength. Conceptual strength focuses on the degree to which a mark is descriptive in that it “directly and immediately convey[s] some knowledge of the characteristics of products.” Commercial strength focuses on the “marketplace recognition value of the mark.”

The Federal Circuit explained the relevance of third-party registrations and their bearing on a mark’s conceptual strength, noting that the Board erred in assigning a low probative value to 15 composite marks of record. The Court explained that composite third-party marks are relevant to resolving the question of whether the “shared segment—in this case, ‘flex’—has a commonly understood” meaning in the pertinent field and to the crowded nature of the field in which the flex root is used. As the Court explained, proof of use or non-use is material because the sixth DuPont factor only considers [...]
