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 [...]

Sole Searching: Trade Dress Hopes Booted as Functional, Nondistinctive

by Keval Amin | Apr 25, 2024 | Trademarks

The US Court of Appeals for the Fourth Circuit affirmed a district court’s summary judgment grant in a trademark dispute, finding that the district court did not err in concluding that a subset of design elements lacked distinctiveness in the public’s view. TBL Licensing, LLC v. Katherine Vidal, Director of the United States Patent and Trademark Office, Case No. 23-1150 (4th Cir. Apr. 15, 2024) (Quattlebaum, Gregory, Benjamin, JJ.)

TBL Licensing is commonly known as Timberland, the prominent footwear manufacturer. Timberland tried to register specific design elements of its popular boot as protected trade dress with the US Patent & Trademark Office (PTO). In its application, Timberland provided a detailed written description of the boot design elements it sought to register as protectable trade dress. Timberland also included a drawing of these design elements.

The PTO rejected Timberland’s application, finding that the design was functional and lacked distinctiveness. Timberland appealed to the Trademark Trial & Appeal Board, which affirmed. Timberland then challenged the Board’s decision in the US District Court for the Eastern District of Virginia. The district court granted summary judgment in favor of the PTO because Timberland’s design was functional and had not acquired distinctiveness. Timberland appealed.

Timberland argued that the district court improperly segmented the design during its functionality analysis. Timberland argued that the district court failed to meaningfully consider the design as a whole, and even if it did, the court erred in considering specific factors, including the availability of alternative designs and the design’s simplicity in manufacturing. The court also relied on inapposite patents and advertisements as evidence to support its functionality finding, an analysis that Timberland argued was improper.

The Fourth Circuit affirmed the district court’s decision. While acknowledging the potential error in the district court’s failure to analyze the design holistically, the Court ultimately found that the limited design elements Timberland sought to register lacked secondary meaning – a crucial element for trade dress protection. The Court employed a secondary meaning analysis to assess public perception of Timberland’s design and considered various factors, including advertising expenditures, consumer studies, sales success, unsolicited media coverage, attempts at imitation and length of exclusive use.

Applying each factor, the Fourth Circuit determined that the district court did not clearly err in finding that the design elements lacked distinctiveness. The Court explained that the district court highlighted flaws in Timberland’s consumer survey, noting suggestive questions and a lack of focus on the claimed design features. The district court also emphasized that Timberland’s advertising expenditures did not effectively link the claimed design features with Timberland in consumers’ minds. Timberland’s arguments regarding sales success, media coverage and attempts at plagiarism were also found insufficient to establish secondary meaning. Lastly, the presence of similar-looking boots from other manufacturers undermined Timberland’s claim of exclusivity in using the design.

Lacking direct consumer survey evidence, the Fourth Circuit determined that Timberland’s circumstantial evidence failed to [...]

PTO Proposes New Guidelines for Director Review in Board Proceedings

by Jake B. Vallen | Apr 25, 2024 | America Invents Act, Patents

The US Patent & Trademark Office (PTO) proposed new rules governing the process for Director review of Patent Trial & Appeal Board decisions in America Invents Act (AIA) proceedings. Rules Governing Director Review of Patent Trial and Appeal Board Decisions, 89 Fed. Reg. 26,807 (proposed Apr. 16, 2024) (to be codified at 37 C.F.R. pt. 42).

The Notice of Proposed Rulemaking (NPRM) proposes adding 37 C.F.R. § 42.75, which includes rules addressing the following issues:

Limited Availability of Director Review. The NPRM proposes that Director review in AIA proceedings would only be available to a party from institution decisions, final written decisions or panel decisions granting rehearing of a decision on institution or a final written decision. However, the Director would have authority to review any interlocutory decisions rendered in reaching such decisions. The NPRM also proposes that the Director may sua sponte review institution decisions, final written decisions or decisions granting rehearing.

Timing, Format and Content of Requests for Director Review. The NPRM proposes that requests for Director review would have to be sought within the time period set forth by 37 C.F.R. § 42.71(d), comply with the formatting and length requirements of 37 C.F.R. §§ 42.6(a) and 42.24(a)(1)(v), and would not be allowed to introduce new evidence. Any sua sponte Director review would have to be initiated within 21 days after the deadline to seek rehearing.

Effect of Director Review. The NPRM proposes that a decision on institution, a final written decision or a decision granting rehearing would become final agency action unless Director review was timely sought or timely initiated sua sponte or a request for Director review was denied.

Director Review Process. The NPRM proposes that Director review would not stay the underlying proceeding, but if the Director grants review, the review would conclude with the issuance of a decision or order that provides the reasons for the Director’s disposition of the case. A party would be permitted to appeal a Director review decision of either a final written decision or a decision granting rehearing of a final written decision (not institution decisions or decisions granting rehearing of institution decisions) to the Federal Circuit in accordance with the procedures set forth in 35 U.S.C. §§ 141(c) and 319. A request for Director review would be treated as a request for rehearing and would reset the time for appeal until Director review was resolved.

Delegation. The NPRM proposes that delegation of Director review would be permitted, subject to conditions set forth by the Director.

Communications With the PTO. The NPRM proposes that communications from a party concerning a specific Director review request or proceeding would have to copy counsel for all parties. Other than authorized amicus briefings, communications from third parties would not be allowed.

Comments are due by June 17, 2024, and can be submitted through the federal eRulemaking portal here.

Virtually Done: Computer Visualization Patents Are Ineligible for Protection

by Courtney Seams | Apr 18, 2024 | Patents

Addressing subject matter eligibility under 35 U.S.C. § 101, the US Court of Appeals for the Federal Circuit upheld the district court’s finding that patents related to computer visualizations of medical scans were patent ineligible. AI Visualize, Inc. v. Nuance Communications, Inc., Case No. 22-2019 (Fed. Cir. Apr. 4, 2024) (Moore, Reyna, Hughes, JJ.)

AI Visualize asserted four related patents, each having a substantially similar specification and the same title, against Nuance Communications. The patents are generally directed at systems and methods for users to virtually view a volume visualization dataset (a three-dimensional collection of data representing the scanned area of an MRI) on a computer without having to transmit or locally store the entirety of the dataset.

Nuance moved to dismiss the case, asserting that the claims were directed to patent-ineligible subject matter and invalid under § 101. The district court applied the two-step Alice inquiry to the claims, which the parties had grouped into three representative claims:

Claims where a web application directs the server to check what frames of a virtual view are stored locally and creates any additional frames necessary to create and display the virtual view of the medical image.
Claims with the further requirement that any previously requested virtual view be given a unique key, which the server checks for (and displays if the key exists) prior to completing the steps of the independent claim.
Claims without the requirement of checking to see if any images are stored locally.

In applying part one of Alice, the district court concluded that the asserted claims were directed to the abstract idea of “retrieving user-requested, remotely stored information” and not, as AI Visualize argued, to improvements in computer functionality. The district court then applied Alice step two and considered each of the three representative claims. The district court concluded that none of the claim limitations transformed the claims into patent-eligible applications of an abstract idea. Ultimately, the district court determined that all asserted claims were patent ineligible under § 101. AI Visualize appealed.

The Federal Circuit also applied the Alice analytical framework. Applying Alice step one, the Court considered whether the focus of the claimed advance was on an improvement in computer technologies, rather than the use of computers, and whether the claim limitations described a claimed advance over the prior art. The Court upheld the district court’s finding under Alice step one (i.e., that all three types of asserted claims were directed to an abstract idea) because the steps of obtaining, manipulating and displaying data, when claimed at a high level of generality, constitute an abstract concept. The Court did not agree with AI Visualize’s arguments that the creation of the virtual views is a technical solution to a technical problem because it requires the creation of “on the fly” virtual views at the client computer. In doing so, the Court refused to import details from the specification into the claims.

Applying Alice step two, the Federal Circuit upheld the district court’s finding that [...]

New Guidance Addresses Use of AI Systems, Tools in Practice Before the PTO

by Peter Brunovskis, PhD | Apr 18, 2024 | Technology

The US Patent & Trademark Office (PTO) issued new guidance on the use of artificial intelligence (AI) tools in practice before the PTO. The new guidance is designed to promote responsible use of AI tools and provide suggestions for protecting practitioners and clients from misuse or harm resulting from their use. This guidance comes on the heels of a recent memorandum to both the trademark and patent trial and appeal boards concerning the applicability of existing regulations addressing potential misuse of AI and recent guidance addressing the use of AI in the context of inventorship.

Patent practitioners are increasingly using AI-based systems and tools to research prior art, automate the patent application review process, assist with claim charting, document reviews and gain insight into examiner behavior. The PTO’s support for AI use is reflected in patent examiners’ utilization of several different AI-enabled tools for conducting prior art searches. However, because AI tools are not perfect, patent practitioners are potentially vulnerable to misuse or misconduct. Therefore, the PTO’s new guidance discusses the legal and ethical implications of AI use in the patent system and provides guidelines for mitigating the risks presented by AI tools.

The guidance discusses the PTO’s existing rules and policies for consideration when applying AI tools, including duty of candor, signature requirement and corresponding certifications, confidentiality of information, foreign filing licenses and export regulations, electronic systems’ policies and duties owed to clients. The guidance also discusses the applicability of these rules and policies with respect to the use of AI tools in the context of document drafting, submissions, and correspondence with the PTO; filing documents with the PTO; accessing PTO IT systems; confidentiality and national security; and fraud and intentional misconduct.

AI tools have been developed for the intellectual property industry to facilitate drafting technical specifications, generating responses to PTO office actions, writing and responding to briefs, and drafting patent claims. While the use of these tools is not prohibited, nor is there any obligation to disclose their use unless specifically requested, the guidance emphasizes the need for patent practitioners to carefully review any AI outputs generated before signing off on any documents or statements made to the PTO. For example, when using AI tools, practitioners should make a reasonable inquiry to confirm that all facts presented have evidentiary support, that all citations to case law and other references are accurately presented, and that all arguments are legally warranted. Any errors or omissions generated by AI in the document must be corrected. Likewise, trademark and Board submissions generated or assisted by AI must be reviewed to ensure that all facts and statements are accurate and have evidentiary support.

While AI tools can be used to assist or automate the preparation and filing of documents with the PTO, care must be taken to ensure that no PTO rules or policies are violated and that documents are reviewed and signed by a person, not an AI tool or non-natural person. AI [...]
