Clean Up on Aisle PTAB: Clarification of Discretionary Denial Practice

by | May 2, 2024 |

The US Patent & Trademark Office (PTO) issued a Notice of Proposed Rulemaking (NPRM) for inter partes review (IPR) and post-grant review (PGR) proceedings before the Patent Trial & Appeal Board, seeking to codify existing precedent and guidance regarding the Board’s discretionary considerations in denying IPR or PGR petitions. 89 Fed. Reg. 28693 (Apr. 19, 2024).

The NPRM follows a 2020 request for comments and an April 2023 Advance Notice of Proposed Rulemaking (ANPR) that the PTO had hoped to finalize in terms of rulemaking by fall 2023. However, proposals in the ANPR hit a snag following criticism from Congress and more than 14,500 comments from stakeholders and the public, including charges that the PTO Director was overstepping her authority.

The newly proposed rules address:

  • Briefing on motions for discretionary denial
  • Factors for discretionary denial
  • Termination and settlement agreements

Briefing on Motions for Discretionary Denial

A significant aspect of the proposal provides for a separate briefing schedule between a patent owner’s preliminary response (POPR) and a request for discretionary denial, which must be filed no later than one month prior to the deadline for the POPR for briefing on its merits. Under the proposal, the discretionary denial arguments would be excluded from the preliminary response unless otherwise authorized by the Board and are intended to avoid encroaching on the wordcount limits for briefing on the merits. Under the proposed briefing process, there would be a 10-page limit for a patent owner’s request for discretionary denial and for the petitioner opposition, and a five-page limit for the patent owner’s sur-reply.

Factors for Discretionary Denial

The proposed rules address denial of institution for “parallel petitions” or “serial petitions” to provide a framework for considering whether previously presented art or arguments provide grounds for denial. The proposed rules also address treatment of joinder petitions, particularly in relation to already instituted petitions. Parallel petitions are defined in the proposed rule as two or more petitions by the same petitioner challenging the same patent that are filed on or before the filing of a POPR to any of the petitions or on or before the due date for filing a POPR to the first petition. Serial petitions are defined as challenged claims of the same patent overlapping with those in a previously filed petition for IPR, PGR or covered business method patent review.

According to the proposed rules, a parallel petition would not be instituted without a good cause showing of why more than one petition is necessary. Factors for a good cause showing include:

  • A petitioner’s ranking of desired petitions for consideration
  • An explanation of differences and materiality between the petitions
  • The number of challenged patent claims, including those asserted by the patent owner in district court litigation
  • A priority date dispute
  • Alternative claim constructions requiring different prior art references on mutually exclusive grounds
  • Knowledge of asserted claims at the time of filing a petition
  • Complexity of the technology

Similar considerations would also apply to joinder petitions.

Cross-Appeals Fail to Strike a Chord

by | May 2, 2024 |

In the latest development in the ongoing litigation saga between competitors Sonos and Google, the US Court of Appeals for the Federal Circuit affirmed the US International Trade Commission’s determination that the original accused audio players and controllers infringed the asserted patents while redesigned products did not. Sonos, Inc. v. Int’l Trade Comm’n, Case No. 22-1421 (Fed. Cir. Apr. 8, 2024) (Stark, Dyk, Reyna, JJ.) (nonprecedential).

Sonos filed a complaint against Google at the Commission, asserting that Google’s importation of certain audio players and controllers infringed Sonos’s patents generally directed to connecting and controlling wireless speakers. The chief administrative law judge made an initial determination that Google’s originally accused products infringed each of the asserted patents but also found that Google’s redesigned products were noninfringing alternatives. After declining the parties’ petitions for review, the Commission issued a final determination adopting the chief administrative law judge’s initial determination and entered a limited exclusion order. Sonos appealed the Commission’s determination concerning the redesigned products, and Google cross-appealed the Commission’s determination concerning the original products.

Sonos argued that the Commission misconstrued disputed claim terms and lacked substantial evidence for its noninfringement findings. First, Sonos argued that the Commission misconstrued claim language reciting “at least a second message containing network configuration parameters,” which “comprise an identifier of the secure WLAN . . . and a security key.” The Commission construed this language as requiring a single second message with both the claimed identifier and security key while Sonos contended that the claim language contemplated multiple second messages that collectively contain the identifier and security key. The Federal Circuit disagreed with Sonos, noting that the specification provided strong support for the Commission’s construction. Because Google’s redesigned product transmitted the identifier and the key in separate messages, the Federal Circuit affirmed the Commission’s conclusion that Google did not infringe.

Sonos next took issue with the Commission’s determination that Google’s redesigned product, which included an incrementing integer counter for synchronizing playback among devices, did not infringe a claim requiring synchronization through “time clock information.” While Sonos framed the issue as one of claim construction, the Federal Circuit reasoned that it was actually a factual issue (whether the accused redesign infringed), which is reviewed for substantial evidence. Because Google’s experts explained that an incrementing counter does not represent a time value, the Court concluded that the Commission’s determination was supported by substantial evidence.

Finally, Sonos contested the Commission’s construction of “equalization” as requiring “alteration of the relative strength of certain frequency ranges in the audio data” by adjusting certain properties of a speaker driver, adjusting amplifier gain in a playback device or using a filter. Finding this construction too narrow, Sonos argued that “equalization” should include any modification to output audio data, including the changing of a channel output without altering strengths of a frequency range. The Federal Circuit agreed with the Commission’s construction, which was based on expert testimony and dictionaries demonstrating that “equalization” is a well-known audio technique used to enhance or diminish specific frequency ranges.

Unclean Hands Aren’t Just for Toddlers

by | Apr 25, 2024 |

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 | Apr 25, 2024 |

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 | Apr 25, 2024 | ,

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.

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

by | Apr 18, 2024 |

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 [...]

Drawing Can Teach Claim Limitations If “Clear on Its Face”

by | Apr 18, 2024 |

Addressing when a drawing in a prior art reference includes a teaching that is “clear on its face,” the Director of the US Patent & Trademark Office vacated and remanded a Patent Trial & Appeal Board decision denying institution of an inter partes review (IPR) petition. MAHLE Behr Charleston Inc. v. Catalano, IPR2023-00861 (PTAB Decision Review, Apr. 5, 2024) (Vidal, PTO Dir.)

MAHLE Behr filed a petition requesting institution of an IPR, challenging claims of a patent owned by Catalano. The patent is directed to a device known as a sacrificial anode that prevents corrosion in motor vehicle radiators caused by electrolysis. One of the claim terms at issue requires the anode to be “within 10 inches” of another element. MAHLE argued that a figure in a prior art reference anticipated or rendered obvious several challenged claims.

The Board denied the institution after determining that MAHLE did not establish a reasonable likelihood that it would prevail with respect to at least one of the challenged claims. The Board cited the Federal Circuit’s 2000 decision in Hockerson-Halberstadt v. Avia Group International to explain that “[p]atent drawings do not define the precise proportions of the elements and may not be relied on to show particular sizes if the specification is completely silent on the issue.” The Board concluded that the figure relied on by MAHLE did not provide exact dimensions and thus could not be sufficient to render the claims invalid.

MAHLE filed a request for Director Review, which was granted. In its request, MAHLE argued that the Board erred in its application of Federal Circuit case law on the use of patent drawings as prior art teachings. The Director agreed, explaining that “the Board did not adequately address [MAHLE’s] arguments regarding what [the figure in the prior art] clearly shows or would have reasonably suggested to a person of ordinary skill in the art.” Federal Circuit case law established that a claim may be anticipated or rendered obvious by a figure in the prior art if the drawing clearly discloses the claim limitation. If “a person of skill in the art could derive the claimed dimensions from the patent’s disclosure, there is no additional requirement that the specification must explicitly disclose the precise proportions or particular sizes.”

The Director further explained that “the Board did not adequately address MAHLE’s arguments regarding what [the prior art figure] clearly shows or would have reasonably suggested to a person of ordinary skill in the art.” While the prior art figure did not disclose the precise proportions or measured quantity specified in the challenged claims, the figure showed the elements being located as claimed (necessarily within the 10 inches recited). The Director explained that the Board should have considered whether a person of ordinary skill in the art would have understood the figure to disclose the claimed elements being within 10 inches of each other.

The Director vacated the Board’s decision and remanded the petition with instructions to consider both what the prior art figure [...]

ITU Applicants Beware: Federal Courts Have Jurisdiction Over Pending Trademark Applications

by | Apr 11, 2024 |

The US Court of Appeals for the Ninth Circuit affirmed in part a district court’s ruling in a trademark dispute, upholding its decision to invalidate trademark applications. The Ninth Circuit held that district courts have jurisdiction to alter or cancel trademark applications in an action properly brought under 15 U.S.C. § 1119, and that in the context of challenges to intent-to-use (ITU) applications, proof of a lack of bona fide intent can invalidate. BBK Tobacco & Foods LLP v. Central Coast Agriculture, Inc., Case Nos. 22-16190; -16281 (9th Cir. Apr. 1, 2024) (Hurwitz, Desai, JJ.) (Bumatay, J., dissenting).

BBK sells and distributes smoking-related products with BBK’s “RAW” branding. Central Coast Agriculture (CCA) sells cannabis products using “Raw Garden” branding. BBK filed a complaint against CCA including claims of trademark infringement and a petition to void several ITU trademark applications owned by CCA for lack of a bona fide intent to use the relevant trademarks in commerce. Instead of disputing the merits of BBK’s claims, CCA argued that the district court had no jurisdiction to adjudicate this issue. The district court granted summary judgment in favor of BBK on its claims to invalidate the trademark applications. CCA appealed.

The Ninth Circuit affirmed the summary judgment in favor of BBK on its claims to invalidate CCA’s trademark applications. The Court explained that “when an action involves a claim of infringement on a registered trademark, a district court also has jurisdiction to consider challenges to the trademark application of a party to the action.” The Lanham Act, at 15 U.S.C. § 1119, provides that “[i]n any action involving a registered mark the court may determine the right to registration, order the cancelation of registrations, . . . restore canceled registrations, and otherwise rectify the register with respect to the registrations of any party to the action.” The Lanham Act, at § 1051, defines an application for use of trademark as a “request for registration of a trademark on the principal register.” Because a challenge to an application affects the applicant’s right to the registration, the Court reasoned that § 1119 authorizes a district court to resolve disputes over trademark applications.

The Ninth Circuit held that a “lack of bona fide intent to use a mark in commerce is a valid basis to challenge a trademark application,” aligning with decisions in sister circuits and the Trademark Trial & Appeal Board. An applicant can seek to register a mark if the mark is already being used in commerce or if the applicant has a bona fide intention, under circumstances showing the good faith of such person, to use a trademark in commerce. While applicants filing under the ITU provisions may begin the registration process based on a bona fide intent to later use the mark in commerce, the Lanham Act requires such applicants to either subsequently file a verified statement of actual use of the mark or convert their application into a use application. As a result, the Ninth Circuit affirmed the district court’s ruling [...]

Reasonable Royalty Available for Foreign Activities (But Not This Time)

by | Apr 11, 2024 |

The US Court of Appeals for the Federal Circuit affirmed a district court’s decision to preclude a patent owner from seeking damages based on method claims infringed outside of the United States but confirmed that reasonable royalties are available based on foreign activities. Harris Brumfield v. IBG LLC, Case No. 22-1630 (Fed. Cir. Mar. 27, 2024) (Prost, Taranto, Hughes, JJ.)

Trading Technologies International (TT), whose successor is Harris Brumfield, filed a lawsuit against IBG in 2010 alleging infringement of four patents directed to graphical user interfaces for commodity trading and methods for placing trade orders using those interfaces. During the underlying proceeding, the district court issued several orders. The district court granted IBG’s motion for summary judgment that the claims of two of the patents were invalid. The district court also excluded one of TT’s damages theories concerning foreign activities. Prior to trial, the district court found that two of the patents were invalid as patent ineligible and that the other two patents contained patent eligible subject matter. The district court also excluded one of TT’s damages theories concerning foreign activities.

The case proceeded to trial on the two remaining patents, and the jury found the asserted claims of those two patents infringed. IBG proposed $6.6 million in damages, which corresponds to the total demanded by IBG using IBG’s proposed royalty rate measured against domestic usage, rather than global users. By contrast, TT proposed damages of $962 million, which included all worldwide users of the accused product, regardless of whether they performed the claimed method. The jury agreed with IGB and awarded TT $6.6 million. the district court denied TT’s post-verdict motion for a new trial on damages, a motion in which TT alleged that IBG had misrepresented how it calculated the damages figures it presented to the jury. TT appealed.

Under the Supreme Court’s 2018 decision in WesternGeco v. Ion Geophysical, a patent owner can recover damages in the form of foreign lost profits when infringement is found under 35 U.S.C. § 271(f)(2) of the Patent Act. TT argued that under WesternGeco, it can seek damages in the form of a reasonable royalty based on IBG “making” the accused product in the US, even though the products were used overseas. The Federal Circuit engaged in a detailed description of WesternGeco, concluding that the Court must examine the particular acts alleged to constitute infringement under particular statutory provisions to determine if the allegations focus on domestic conduct. The Court explained that under § 271(a), the making, using, offering to sell and selling provisions are limited to domestic acts. The Court acknowledged that the WesternGeco framework applies to reasonably royalty awards (not just lost profits) and that a reasonable royalty would be the amount a hypothetical infringer would pay to engage in the domestic acts constituting the infringement.

Despite finding that reasonable royalties are permitted under WesternGeco, the Federal Circuit affirmed the district court’s exclusion of TT’s damages theory because TT’s infringement theory about making the accused product [...]

Faulty Jury Instruction Tampered With Tamper-Proof Trial

by | Apr 4, 2024 |

The US Court of Appeals for the Federal Circuit affirmed in part, vacated in part and remanded a district court decision after concluding that a jury instruction on the objective indicia of nonobviousness that failed to specify all indicia on which evidence had been received constituted prejudicial legal error. Inline Plastics Corp. v. Lacerta Group, LLC, Case Nos. 22-1954; -2295 (Fed. Cir. Mar. 27, 2024) (Taranto, Chen, Hughes, JJ.)

Inline Plastics owns a patent family pertaining to containers with specific tamper-proof features and methods of producing these containers using thermoformed plastic. The invention is intended to deter unauthorized tampering with products in the containers. These tamper-proof features serve to prevent theft and product loss and maintain consumer confidence in product integrity.

Inline sued Lacerta Group for patent infringement over its tamper-proof technology. The district court made several significant pretrial rulings, including a claim construction order, and granted Inline’s motion for partial summary judgment of infringement on some of the asserted claims. During trial, Inline voluntarily withdrew certain claims, and the jury returned a verdict declaring all remaining claims (even those on which summary judgment had been granted) invalid and not infringed. After trial, Inline sought partial final judgment, which was granted, but also motioned for judgment as a matter of law and a new trial on invalidity. The district court denied Inline’s motions. Both Inline and Lacerta appealed.

Inline argued that it was entitled to judgment as a matter of law of no invalidity and that an error in the jury instructions requires a new trial on invalidity. Lacerta cross-appealed, challenging the denial of attorneys’ fees and the “without prejudice” dismissal of certain patent claims that Inline voluntarily dropped from its asserted-claims list near the end of trial.

The Federal Circuit rejected Inline’s argument for judgment as a matter of law of no invalidity but agreed with Inline that the jury instruction on the objective indicia of nonobviousness constituted prejudicial legal error. The Court determined that the jury could have reasonably found obviousness and rejected Inline’s three arguments against it. First, Inline argued deficiencies in Lacerta’s prior art references and expert testimony, but the Court found these arguments unpersuasive. Second, Inline challenged Lacerta’s evidence of motivation to combine references, but the Court found enough support to prove a motivation to combine. Third, Inline argued that Lacerta’s challenge failed because there was no rebuttal or opinion on objective-indicia evidence. The Court dismissed this argument, explaining that the absence of such testimony did not necessarily discredit the patentee’s evidence on nonobviousness. According to the Court, Inline failed to explain why the jury could not reasonably assign little weight to its objective-indicia evidence, which led the Court to reject Inline’s categorical argument based on the absence of expert testimony from Lacerta’s side.

However, the Federal Circuit agreed with Inline’s argument for a new trial on invalidity. The Court explained that jury instructions must be legally correct and sufficiently comprehensive to address disputed evidence. The Federal Circuit concluded that the district court’s objective-indicia instruction [...]
