Texas Hammer Nails Trademark Infringement Appeal

by | Sep 2, 2021 |

The US Court of Appeals for the Fifth Circuit reversed a district court’s dismissal of an initial confusion trademark complaint, finding that the plaintiff alleged a plausible claim of trademark infringement under the Lanham Act. Adler v. McNeil Consultants, LLC, Case No. 20-10936 (6th Cir. Aug. 10, 2021) (Southwick, J.)

Jim Adler is a personal injury lawyer who trademarked and used several terms, including JIM ADLER, THE HAMMER and TEXAS HAMMER, to market his business, including via keyword advertisements. McNeil Consultants, a personal injury lawyer referral service, purchased keyword ads using Adler’s trademarked terms, which allowed McNeil’s advertisements to appear at the top of any Google search of Adler’s trademarked terms. McNeil’s advertisements used generic personal injury terms, did not identify any particular law firm and clicking on the ads placed a phone call to McNeil’s call center rather than directing the user to a website. The call center used a generic greeting so consumers did not realize with whom they were speaking.

Adler filed suit against McNeil, asserting Texas state law claims as well as trademark infringement under the Lanham Act. McNeil moved to dismiss, arguing that its keyword ads did not create a likelihood of confusion. The district court agreed and dismissed Adler’s complaint. Adler appealed.

To successfully plead a trademark infringement claim under Fifth Circuit law, the holder of a protectable trademark must establish that the alleged infringing use “creates a likelihood of confusion as to source, affiliation, or sponsorship.” To determine whether a likelihood of confusion exists, the Court weighs a non-exhaustive list of several confusion factors, including the similarity of the marks, the similarity of the products, the defendant’s intent and the care exercised by potential consumers.

The Fifth Circuit explained that Adler alleged initial interest confusion, which exists where the confusion creates consumer interest in the infringing party’s services even where no sale is completed because of the confusion. The Court noted that this case presented the first opportunity for the Fifth Circuit to consider initial interest confusion as it pertains to search engine keyword advertising. Relying on Ninth Circuit precedent and parallel reasoning to its own opinions on initial interest confusion in the context of metatag usage, the Court concluded that Adler’s complaint alleged a plausible claim of trademark infringement under the Lanham Act.

The Fifth Circuit noted that initial interest confusion alone is not enough to raise a Lanham Act claim. The Court explained that if a consumer searches TOYOTA and is directed to search results containing a purchased ad clearly labeled as selling VOLKSWAGEN products, a consumer who clicks on the VOLKSWAGEN ad has been distracted, not confused or misled into purchasing the wrong product. Distraction does not violate the Lanham Act. However, the Court explained that where the use of keyword ads creates confusion as to the source of the advertisement—not mere distraction—an infringement may have occurred. Because McNeil’s advertisements were admittedly generic and could have been associated with any personal injury law firm, the Court found that the keyword [...]

No Service, No Notice

by | Sep 2, 2021 |

Addressing the notice requirements of Fed. R. of Civ. Pro. 65(a)(1), the US Court of Appeals for the Fifth Circuit vacated a preliminary injunction, finding that the aggrieved party did not have sufficient notice of the possibility of a preliminary injunction. Document Operations, L.L.C., v. AOS Legal Tech., Inc., Case No. 20-20388 (5th Cir. Aug. 23, 2021) (Per Curiam) (unpublished).

In 2017, Doc. Ops. entered into a licensing agreement by which AOS Japan would serve as the company’s exclusive representative and marketing provider in Japan for its virtual data room technology. Later, Doc. Ops. learned that a competing product known as AOS VDR had been developed by AOS Korea and would soon be marketed in the two Asian countries. Despite protests from AOS Japan that AOS Korea developed AOS VDR independently, Doc. Ops. filed suit alleging violation of the Texas Uniform Trade Secrets Act and for common law breach of contract, fraudulent inducement, conversion, civil conspiracy and breach of fiduciary duty.

The licensing agreement mandated that AOS Japan protect Doc. Ops.’ confidential information and also prohibited AOS Japan from acting to “represent, promote, develop, or otherwise try to sell within [Japan] any lines of product that. . . compete with [the technology].” Doc. Ops. sought a temporary restraining order (TRO) as well as preliminary injunction and filed and emailed copies of the complaint and TRO motion to AOS representatives. Once a Zoom hearing was scheduled, Doc. Ops. again contacted AOS to inform it of the hearing date. When AOS failed to appear at the hearing, the district court chose to reschedule the hearing three weeks later in order to ensure that AOS was aware of the hearing.

During this three-week interval, Doc. Ops. continued to communicate relevant dates and filings with AOS, which had appointed Texas-based counsel. One of these communications included a letter from Doc. Ops. to the district court stating that if the district court granted its TRO motion, Doc. Ops. would seek to conduct limited expedited discovery to prepare for a subsequent preliminary injunction. AOS failed to appear at the second hearing, stating that it would not appear until served with process. Subsequently, the district court not only granted the TRO motion and the related request for expedited discovery but also issued a preliminary injunction against AOS. AOS appealed both the preliminary injunction and the order granting expedited discovery.

The Fifth Circuit first explained that Rule 65 requires sufficient notice for a preliminary injunction, which the Supreme Court of the United States has interpreted as implying a hearing where the defendant is given a fair opportunity to oppose the preliminary injunction. The Court contrasted the notice requirement for preliminary injunctions from the more informal notice requirement for TROs. While TRO hearings are sometimes converted into preliminary injunction hearings, this conversion has two requirements: Sufficient notice and an opportunity to meaningfully prepare and respond.

The Fifth Circuit found that while AOS certainly had notice that a preliminary injunction was looming, it lacked sufficient notice that this relief would [...]

The Application of “Authentication by Comparison” at the PTAB

by | Aug 26, 2021 |

Directly addressing the application and operation of the Federal Rules of Evidence in proceedings before the Patent Trial & Appeal Board (Board), the US Court of Appeals for the Federal Circuit affirmed-in-part and reversed-in-part two inter partes review (IPR) decisions, criticizing the Board’s refusal to consider a particular reference relied upon by the patent challenger on the basis of failure to authenticate. Valve Corp. v. Ironburg Inventions Ltd., U.S. Federal Circuit Court of Appeals Nos. 20-1315, -1316, -1379 (Fed. Cir. Aug. 17, 2021) (Dyk, J.)

The Board found that an IPR petitioner, Valve Corporation, failed to show that several challenged patents were unpatentable based on a non-authenticated copy of a critical prior art reference (the Burns article). The Burns article was a printed copy of a 2010 online review of an Xbox 360 controller. Simon Burgess, a co-inventor of the patents at issue, had facilitated the publication of the Burns article by providing a test controller to Dave Burns (who worked for an online gaming magazine) for promotional purposes. Valve appealed the Board’s decision.

Valve argued that the Burns article copy submitted in connection with the IPR (the Exhibit) was merely a printout of the same online article cited and enclosed in the prosecution histories of the challenged patents, as well as another of Ironburg’s patents directed toward similar subject matter. The Board concluded that Valve failed to show that the Exhibit was the same version of the Burns article that appeared in the prosecution history and that it was not obligated to compare the documents in the absence of testimony from Valve that the two were identical. Valve appealed.

In reviewing the Board’s decision, the Federal Circuit first referred to the principles of authentication by comparison under Fed. R. Evid. 901(b)(3), which permits authentication of a document by a comparison with an authenticated specimen “by an expert witness or the trier of fact.” While the Court did note a discrepancy in the dates shown in the Exhibit and in the Burns article in one of the prosecution histories, the Court found that the difference in dates did not bear on the subject matter being disclosed, which was “virtually identical” between the two, as well as identical to the version of the same article in the other two relevant file histories. The Court held that the Board was obligated to perform this comparison and erred by failing to do so.

After determining that the Exhibit was “substantively the same” as the versions of the Burns article from the relevant prosecution file histories, the Court addressed the question of whether the Exhibit was a printed publication under 35 U.S.C. § 102(a)(1). The Board found “overwhelming evidence” that the Burns article was accessible prior to the critical date of the patents at issue, based in significant part on the fact that Mr. Burgess had provided a controller to Mr. Burns with the purpose of a “dialogue with the intended audience,” an indicia of public accessibility. The Board also noted its agreement with [...]

Objective Indicia of Nonobviousness for Design Patents: Same Nexus Requirement as Utility Patents

by | Aug 26, 2021 |

The US Court of Appeals for the Federal Circuit reversed two decisions by the Patent Trial & Appeal Board (Board), finding that a soup company and soup dispenser manufacturing company failed to prove the unpatentability of two design patents covering can dispensers. The Court also concluded that the analysis for objective indicia of nonobviousness for utility patents also applies to design patents. Campbell Soup Co. v. Gamon Plus, Inc., Case Nos. 20-2344, 21-1019 (Fed. Cir. Aug. 19, 2021) (Moore, J.)

Gamon Plus owns two design patents directed to “the ornamental design for a gravity feed dispenser display,” or a can dispenser. Gamon’s commercialized embodiment is called the iQ Maximizer gravity feed dispenser. For nearly a decade, Gamon sold tens of millions of dollars’ worth of its iQ Maximizer to Campbell Soup. Campbell attributed increased soup sales in part to the iQ Maximizer in its 10-K Securities and Exchange Commission reports (an industry publication) and in an internal marketing study. Campbell later began purchasing similar gravity feed dispensers from Trinity Manufacturing.

Gamon sued Campbell and Trinity for design patent infringement. Campbell and Trinity then petitioned for inter partes review (IPR) of Gamon’s patents. In its final written decisions, the Board found that Campbell and Trinity failed to prove unpatentability because the prior art was not similar enough to the claimed designs to constitute a proper primary reference. Trinity (Campbell) appealed.

In that appeal, the Federal Circuit disagreed, vacated and remanded. On remand, the Board again held that Campbell and Trinity failed to prove unpatentability, finding that the claimed designs would not have been obvious over the prior art. The Board reasoned that although the prior art alone had the same overall visual appearance as the claimed designs, there existed objective indicia of nonobviousness, including Gamon’s commercial success in selling iQ Maximizers to Campbell, Campbell’s praise of—and commercial success in—using the iQ Maximizer and Trinity’s copying of the iQ Maximizer. The Board presumed a nexus between those objective indicia evidences and the claimed designs because it found the iQ Maximizer to be coextensive with the claims, meaning that the product was essentially the disclosed invention with unclaimed features being insignificant. The Board also found that Gamon established such a nexus regardless of the presumption. Campbell and Trinity again appealed.

Again the Federal Circuit reversed, concluding that the claimed designs would have been obvious over the prior art. In doing so, the Court confirmed the Board’s finding that the prior art and the claimed designs shared the same overall visual appearance (which Gamon did not challenge) but found that the Board’s presumption of nexus and finding of a nexus-in-fact between the claimed designs and the evidence of commercial success and praise were not supported by substantial evidence. As for the presumption, the Court considered whether the iQ Maximizer was coextensive with the claimed invention. Nexus is presumed if the objective indicia evidence is tied to a specific product that is “coextensive” with the claimed invention. The Board recognized that the claimed portions of [...]

When Pictures Aren’t Pictures: Real Estate Agent-Generated Floor Plans Are Outside Copyright Infringement Exception for Pictorial Representations

by | Aug 26, 2021 |

Examining whether the Architectural Works Copyright Protection Act enacted in 1990 protects the creation of floor plans, the US Court of Appeals for the Eighth Circuit held that such technical drawings generated for practical, rather than artistic, purposes are not covered by a statutory exception that removes the right to control pictures, paintings, photographs or other pictorial representations of their work from architects. Designworks Homes, Inc. et al. v. Columbia House of Brokers Realty, Inc. et al., Case Nos. 19-3608, 20-1099, -3104, 20-3107 (8th Cir. Aug. 16, 2021) (Arnold, J.)

The facts of the case are relatively simple: In the course of selling designed homes, homebuilders hired real estate agents to generate floor plans for use in their listings. The designers of the homes registered copyrights in the homes themselves, then sued the homebuilders and their real estate agents for copyright infringement.

The issue for the Court was whether 17 U.S.C. § 120(a), a statute designed to limit the scope of copyright protection for architectural works, applied to the floor plans that the real estate agents developed. Section 120(a) excludes from the scope of a copyright in an architectural work “the right to prevent the making, distributing, or public display of pictures, paintings, photographs, or other pictorial representations of the work.” The district court held that the floor plans fell within Section 120(a)’s exclusion and, thus, were not covered by the copyright.

The Eighth Circuit disagreed. Employing numerous canons of statutory construction, the Court held that the functional floor plans were neither pictures nor “other pictorial representations” within the meaning of the statute. Drawing from 1990s dictionaries, the Court reasoned that although a floor plan could conceivably be a picture, context showed otherwise. For example, Congress used the phrase “technical drawings” elsewhere in the copyright statute; thus, had Congress intended to exclude them here, it knew how to do so. Moreover, the types of floor plans at issue here were—in the Court’s view—not similar to the other listed categories of items for which copyright protection had been curtailed as the plans did not have any artistic expression.

Practice Note: Not all hope is lost for the homebuilder or developer. Although the Eighth Circuit declined to expressly consider other defenses, it explained that there were others that very readily could apply, including the doctrine of fair use.

Third Circuit Orders Second Look at Delays and Disgorgement of Profits

by | Aug 26, 2021 |

In a long-running trademark dispute between two charitable organizations, the US Court of Appeals for the Third Circuit found that the appellee did not preserve its challenge to the district court’s denial of summary judgment on its trademark cancelation claims, the appellant waived any challenge to the validity of the defendant’s mark and the district court did not abuse its discretion by declining to award enhanced monetary relief or prejudgment interest. Kars 4 Kids Inc. v America Can!, Case Nos. 20-2813; -2900 (3rd Cir., August 10, 2021) (Shwartz, J.) The Court also vacated-in-part and remanded for the district court to reexamine its laches and disgorgement conclusions under applicable law.

As charitable organizations that sell donated vehicles to fund children’s programs, both America Can (as CARS FOR KIDS) and Kars 4 Kids have used similar trademarks since their respective starts in the early- to mid-1990s. In 2003 and 2013, America Can sent cease and desist letters to Kars 4 Kids after seeing its advertisements in the state of Texas. In 2014, Kars 4 Kids sued America Can for federal and state trademark infringement, unfair competition and trademark dilution claims. Less than one year later, America Can filed its own suit—alleging the same claims—plus a petition to cancel a Kars 4 Kids trademark registration and seeking a nationwide injunction and financial compensation.

Both parties appeal from a denial of their respective summary judgment motions as well as (1) the jury finding that Kars 4 Kids willfully infringed America Can’s trademark rights in Texas, (2) the rejection of America Can’s petition for cancellation of a KARS FOR KIDS trademark registration finding that the registration was not knowingly procured by fraudulent means, (3) the conclusion that laches did not apply against America Can’s claims, (4) disgorgement of Kars 4 Kids profits in Texas totaling about $10.6 million, (5) rejection of enhanced monetary relief and (6) an injunction against Kars 4 Kids with respect to use of its trademark in Texas and from using the carsforkids.com domain name. On appeal, Kars 4 Kids also renewed its motion for judgment as a matter of law, including an argument that America Can’s trademark is invalid.

The Third Circuit rejected Kars 4 Kids’ effort to overturn the jury’s liability verdict, concluding that Kars 4 Kids failed to preserve its challenge to the validity of the CARS FOR KIDS trademark when it left that issue out of its Rule 50(a) motion. Instead, evidence of America Can’s continuous use of the CARS FOR KIDS mark well prior to 2003 predated Kars 4 Kids’ first use of its trademark in Texas in 2003 and established America Can’s ownership of the CARS FOR KIDS trademark in Texas.

However, after examining the laches claim, the Third Circuit explained that it considered (1) the plaintiff’s inexcusable delay in bringing suit and (2) prejudice to the defendant as a result of the delay. With no statute of limitations under the Lanham Act, the parties agreed that their claims are properly analogized to New Jersey’s six-year [...]

When it Comes to Method of Use Claims, Preamble Language Regarding Intended Use is Limiting

by | Aug 26, 2021 |

The US Court of Appeals for the Federal Circuit issued three separate but related rulings (two precedential, one non-precedential) affirming decisions by the Patent Trial & Appeal Board (Board) regarding the validity of nine US patents and addressing the limitations of preamble language and motivation to combine. Eli Lilly Co. v. Teva Pharmaceuticals, Case Nos. 20-1876, -1877, -1878 (Fed. Cir. August 16, 2021) (Lourie, J.); Teva Pharmaceuticals v. Eli Lilly Co., Case Nos. 20-1747, -1748, -1750 (Fed. Cir. August 16, 2021) (Lourie, J.); Teva Pharmaceuticals v. Eli Lilly Co., Case Nos. 20-1749, -1751, -1752 (Fed. Cir. August 16, 2021) (Lourie, J.). These decisions come as the latest events in a dispute between Teva and Eli Lilly Company over competing products for the treatment of migraine headaches.

Teva owns nine patents directed to humanized antagonist antibodies that target calcitonin gene-related peptide. In 2018, the Food and Drug Administration (FDA) first approved Teva’s version of the biologic fremanezumab (Ajovy®) and then approved Lilly’s biologics license application for galcanezumab (Emgality®) eight days later. Both drugs are part of a new class of migraine therapeutic agents called calcitonin gene-related peptide antagonists.

Lilly challenged the validity of Teva’s nine patents covering Ajovy® in a series of inter partes review (IPR) petitions, arguing that the claims were obvious. The Board instituted IPR for all nine Teva patents. The similarity of subject matter and arguments led to three separate written opinions, each addressing three of the patents. In these decisions, the Board upheld the validity of three of the patents at issue (which covered methods of treating migraines with the antibodies) but found the claims of the six other patents directed to the antibodies themselves invalid.

Lilly appealed the first Board ruling covering methods of treating migraines to the Court. Lilly argued that the Board erred by (1) “reading a result into the constructions of the preambles and the term ‘effective amount,’” which led the Board to erroneously require Lilly to prove that a skilled artisan would have had “a reasonable expectation of achieving a result that was not claimed,” and (2) applying a too-high standard when weighing evidence to determine whether a skilled artisan would have a reasonable expectation of success. Lilly contended that a claim preamble containing only a statement of purpose cannot be a claim limitation and that no weight should have been given to the preambles. Teva argued that Lilly was basing its analysis on a false dichotomy between “limiting preambles” and preambles that are mere statements of purpose.

The Federal Circuit found the claim preambles to be limiting, reasoning that claims directed to methods of using compositions “are not directed to what the method ‘is’” but rather to “what the method ‘does,’” which usually is recited in the preamble. The preambles provided the only metric by which one practicing the claim could determine whether the amount administered is an “effective amount” and provided the antecedent basis for at least one later claim term in the independent claims.

After finding the preambles to [...]

Federal Circuit Finds Interlocutory Appeal Untimely

by | Aug 19, 2021 |

Addressing the time limits for filing an interlocutory appeal in patent cases, the US Court of Appeals for the Federal Circuit dismissed such an appeal as untimely, finding that the appellant did not file within 30 days of all liability issues except for a determination of damages being resolved. Mondis Technology Ltd. v. LG Electronics Inc., Case No. 20-1812 (Fed. Cir. Aug. 3, 2021) (Hughes, J.)

Mondis Technology sued LG Electronics for infringement of a patent related to display technology. In a consolidated district court case joining other parties to dispute with LG, a jury found that (1) LG infringed certain claims of the patent owned by Mondis, (2) the patent claims were not invalid and (3) LG’s infringement was willful. The jury awarded $45 million in damages. LG filed multiple post-trial motions relating to infringement, invalidity, willfulness and damages. In September 2019, the district court denied LG’s motions regarding infringement, invalidity and willfulness. Then, in April 2020, the district court granted LG’s motion for a new trial on damages.

Within 30 days of the April 2020 order, LG filed a notice of interlocutory appeal with the Federal Circuit, seeking to challenge the denial of its three post-trial motions.

The Federal Circuit first discussed its jurisdiction to hear interlocutory appeals under 28 U.S.C. § 1292(c)(2), which provides the Court with exclusive jurisdiction over “an appeal from a judgment in a civil action for patent infringement which would otherwise be appealable to the . . . Federal Circuit and is final except for an accounting.” The Court explained that appeals under this section are subject to the time limits of § 2107(a), which in this case would give LG 30 days from the date the judgment became “final except for an accounting.” The Court cited to a previous case in which it held that a judgment is “final except for an accounting” under § 1292(c)(2) when all liability issues have been resolved and only a damages determination remains. The Court further supported its position by citing the Supreme Court of the United States’ 1988 decision in Budinich v. Becton Dickinson in which it found that the merits decision was final after the first post-trial order that resolved all issues except for attorneys’ fees. The Court thus found that all such liability issues were resolved as of the district court’s September 2019 order and that the 30-day clock started at that time.

LG also argued that Rule 4 of the Federal Rules of Appellate Procedure tolled the time to file its appeal. Rule 4(a)(4) provides that “the time to file an appeal runs for all parties from the entry of the order disposing of the last such remaining motion.” The Court disagreed with LG’s characterization, citing a Third Circuit opinion which found that a motion only tolls the time to file interlocutory appeals if the motion relates to the interlocutory judgment. The Court found that Rule 4(a)(4) did toll the time to file the interlocutory appeal but only until motions concerning liability [...]

Without More, Mere Automation is Abstract—Not Construing Interchangeable Terms Doesn’t Give Them the Cold Shoulder

by | Aug 19, 2021 |

In the latest development relating to patent eligibility of content-based identifier patents, the US Court of Appeals for the Federal Circuit affirmed decisions finding patent claims ineligible under 35 U.S.C. § 101. PersonalWeb Techs. LLC v. Google LLC, YouTube, LLC, Case No. 20-1543 (Fed. Cir. Aug. 12, 2021) (Prost, J.) (consolidating PersonalWeb Techs. LLC v. Facebook, Inc., Case No. 20-1553, and PersonalWeb Techs. LLC, Level 3 Commc’ns. LLC v. EMC Corp., VMWare, Inc., Case No. 20-1554).

PersonalWeb sued technology companies in the Eastern District of Texas in 2011 over three of its patents. The patents were directed to data-processing systems that assign each data item a substantially unique content-based identifier, generated by hash algorithm, which changes when the content changes and is used to perform data-management functions. Several defendants successfully motioned for transfer to the Northern District of California, where their companies were headquartered and/or their employees responsible for the development of the accused products were based. After claim construction in Texas, the cases were transferred and stayed pending several inter partes reviews before the US Patent Trial & Appeal Board (Board). Previous decisions before the Federal Circuit affirmed the Board’s findings that using hash-based identifiers for data management was disclosed in the prior art, that content-based identifiers in performing file-management functions, such as backing up files, were also known and other independently unpatentable aspects were recited in the claims. After the stay was lifted, the California court granted the defendants’ motion for judgment on the pleadings that the remaining asserted claims were patent ineligible under 35 U.S.C. § 101. PersonalWeb appealed.

To assess patent eligibility, the Federal Circuit applied the two-step Mayo/Alice framework. Under step one (determining whether the claims at issue are directed to a patent-ineligible concept, such as an abstract idea), the Court considered the focus of the claimed advance over the prior art and found that the claims were directed to an abstract idea. PersonalWeb contended that its claims were directed to “a substantially unique, algorithm-derived, content-based identifier for all data items in a networked computer, which allows a computer within a network containing diverse computing and storage systems to locate and distribute data without knowing either the file system of any device within the network or the conventional name of any data item.” However, the Court adopted the district court’s view, which was that the patents were directed to “(1) using a content-based identifier generated from a ‘hash or message digest function,’ (2) comparing that content-based identifier against something else, [that is,] another content-based identifier or a request for data; and (3) providing access to, denying access to, or deleting data.” Given the focus in Mayo/Alice step one of “whether the claims of the asserted patents fall within the excluded category of abstract ideas,” and citing to parallel examples from precedent cases, the Court concluded that the claims were directed to the use of an algorithm-generated content-based identifier to perform the claimed data-management functions, which include controlling access to data items, retrieving and delivering copies [...]

If Intrinsic Evidence Provides a Clear Meaning, Just Stop

by | Aug 19, 2021 |

The US Court of Appeals for the Federal Circuit vacated a final written decision of the Patent Trial & Appeal Board (Board) based on its finding that the Board erred in its ultimate claim construction by relying on extrinsic evidence that was inconsistent with the intrinsic evidence. Seabed Geosolutions (US) Inc. v. Magseis FF LLC, Case No. 20-1237 (Fed. Cir. Aug. 11, 2021) (Moore, C.J.)

In April 2018, Seabed Geosolutions petitioned for inter partes review of a patent owned by Magseis directed to “seismometers for use in seismic exploration.” Every claim recited a “geophone internally fixed within” either a “housing” or an “internal compartment” of a seismometer. The Board construed this limitation to require a non-gimbaled geophone based entirely on extrinsic evidence. The Board found that the term “fixed” had a special meaning of “non-gimbaled” at the time of the invention. Based on this finding, the Board determined that Seabed had failed to prove that the challenged claims were unpatentable because the cited prior art did not disclose a non-gimbaled geophone. Seabed appealed.

The Federal Circuit reversed the Board’s claim construction of the term “fixed” because it relied on extrinsic evidence that was inconsistent with the intrinsic evidence and unnecessary to consider given the clarity of the intrinsic evidence. The Court reminded the Board that it “resort[s] to extrinsic evidence to construe claims only if it is consistent with the intrinsic evidence,” and that “[i]f the meaning of a claim term is clear from the intrinsic evidence, there is no reason to resort to extrinsic evidence,” citing prior Federal Circuit decisions.

Contrary to the special meaning found by the Board, the Federal Circuit determined that the term “fixed” carried its ordinary meaning (i.e., attached or fastened). The Court found that the term “specifies the geophone’s relationship with the housing, not the type of geophone.” As an initial matter, the specification was silent as to whether the geophone was gimbaled or not. “That silence does not support reading the claims to exclude gimbaled geophones,” in part because the specification used the term gimbaled when describing other aspects of the invention. Had the applicant intended to limit the claimed geophone, it would have done so.

Furthermore, the specification described the internal mounting of the geophone as a key feature to overcome issues with the then-conventional method of separating the geophone from the seismometer’s other components. The specification reiterated that by internally mounting the geophone, the invention was “self-contained.” The prosecution history also revealed that both the applicant and examiner understood the term to carry its plain and ordinary meaning, equating “internally fixed within” with “disposed, and electrically connected, within.” That equivalence indicates that the term was intended to describe the relationship of the geophone with the seismometer, rather than to limit the type of geophone as contemplated by the Board. Accordingly, the Court found that the intrinsic record was clear, and that the Board’s reliance on extrinsic evidence—much less extrinsic evidence that was inconsistent with the specification itself—was improper and remanded for [...]
