Strings Attached: No Amendment for Trademark Application in Inter Partes Opposition Proceeding

by Joshua Revilla | Feb 2, 2023 | Trademarks

The Trademark Trial & Appeal Board (Board) designated as precedential a decision denying a motion to amend and granting partial summary judgment based on a mistaken identification that did not match the goods sold using the trademark. Fender Musical Instruments Corporation v. Win-D-Fender, LLC, Opp. No. 91272326 (TTAB Sept. 22, 2022) (designated precedential Jan. 12, 2023) (Wolfson, Heasley, Cogins, ATJs) (By the Board).

Win-D-Fender applied for a trademark to register the mark EN-D-FENDER for “musical instruments.” Fender opposed this registration on grounds of nonuse, likelihood of confusion and dilution by blurring and filed a motion for summary judgment on the ground of nonuse. Win-D-Fender then filed a motion to amend the identification of goods in its application from “musical instruments” to “musical instrument accessories, namely, an ambient wind foot joint guard for flute family instruments.”

The Board first considered Win-D-Fender’s motion to amend. Under the relevant trademark rules, an application that is subject to an inter partes proceeding may only be amended if the other party consents (Fender did not) and the Board gives approval, or if the Board grants a motion to amend.

Win-D-Fender filed its application via the Trademark Electronic Application System (TEAS). In a TEAS application, only the goods listed in the proper field can be considered for the identification of goods and broadening the scope of the identification is not permitted. In Win-D-Fender’s application, the only goods listed in the “Identification” field were “musical instruments.” Win-D-Fender argued that its application included a miscellaneous statement reading, “For Musical Instrument Accessories namely a wind guard mounted to a flute.” The Board determined, however, that the description was not in the proper field and therefore was not considered in the identified goods. The Board explained that the TEAS Plus instructions warn applicants to not use the TEAS Plus “Identification” field if it does not contain an accurate listing of the goods and services and to instead use the TEAS Standard filing option. The Board noted that although the identification of “musical instruments” may have been a mistake, it is settled that an established identification cannot later be expanded. The Board concluded that Win-D-Fender was limited to amendments that would narrow or clarify the type of “musical instruments.”

Win-D-Fender also argued that musical instrument accessories would fall under the general umbrella of musical instruments. The Board stated that while musical instruments may use accessories, the accessories themselves are not musical instruments and are not encompassed in the “musical instrument” class. The Board, therefore, denied the motion to amend the identification of goods.

The Board next considered Fender’s motion for summary judgment on the ground of nonuse. An application based on use of the mark in commerce is void if the mark was not used in commerce in connection with the goods identified in the application. As the Board had already decided, Win-D-Fender’s mark was limited to musical instruments and did not include accessories. Fender specifically pointed to an interrogatory response in which Win-D-Fender stated that the products sold under the [...]

“Open Sesame” Without Translation Won’t Open Door to Trademark Registration

by Courtney Seams | Feb 2, 2023 | Trademarks

The Trademark Trial & Appeal Board (Board) addressed, for the first time, whether an applicant is required to submit an English translation for a word that is created by spelling out the pronunciation of Chinese characters using Latin characters. The Board concluded that the mark required an English translation and upheld the examining attorney’s refusal to register the mark because there was no translation submitted. In re Advanced New Technologies Co., Ltd., Application No. 86832288 (TTAB Jan. 12, 2023) (Bergsman, Taylor, Heasley, ATJs).

Advanced New Technologies sought to register the mark ZHIMA for several goods and services classes. Advanced has a co-pending application for a mark using Chinese characters, where Advanced stated that “[t]he non-Latin characters in the mark translate to ‘ZHIMA’ and this means ‘SESAME’ in English.” According to Advanced, “the Chinese characters [] pronounced ZHIMA mean ‘sesame,’ but ‘Zhima’ itself has no meaning.” The application for ZHIMA was assigned to Advanced by Alibaba Group Holding Limited. Ali Baba is the hero of an Arabian Nights story who opens the door to a thieves’ den using the magical phrase “open sesame.” The use of the Chinese word for “sesame” on goods thus creates an impression that these goods and services bring customers access to something previously unattainable.

Under 37 C.F.R. § 2.32(a)(9), a trademark application must contain an English translation when the mark includes non-English wording. To determine whether a mark includes non-English wording and its meaning, the examining attorney may use dictionaries and search engines. If the examining attorney discovers that the mark contains non-English wording, the applicant must submit a translation. Following this statutory framework, the examining attorney in this case relied on the Chinese English Pinyin Dictionary, which translates “zhi ma” as “sesame” in English and required Advanced to submit a translation that “ZHI MA” means “sesame” in English.

Advanced argued that individuals fluent in English and Chinese would not transliterate “ZHI MA” back into its Chinese character counterparts, which actually do translate to “sesame.” In response, the examining attorney provided at least eight dictionary definitions where “zhima” was defined as “sesame.” Advanced then argued that the dictionaries were defining the Chinese characters, not the English transliteration because “ZHIMA” itself has no meaning in English.

The examining attorney modified the required translation statement to state that “ZHIMA is a transliteration of Chinese characters that means ‘sesame’ in English.” However, Advanced still refused to submit a translation, claiming that it was not required because there are no Chinese characters in the ZHIMA mark and the meaning of the Chinese characters cannot attach to a mark without them. The examining attorney provided information from many news articles where “zhima” was translated as “sesame.” For example, in articles referencing a Chinese version of Sesame Street, “Sesame” was translated as “Zhima.” The examining attorney also produced multiple websites discussing “zhima” products, all of which were sesame products.

The Board found that the many examples where “zhima” was translated as “sesame” by third parties demonstrated that ZHIMA was not an original [...]

Your Gang Did What!? No Matter—No Forfeiture of IP

by Kathleen Lynch | Jan 26, 2023 | Trademarks

In a unique case blending intellectual property and criminal law, the US Court of Appeals for the Ninth Circuit agreed that a district court properly exercised jurisdiction over a motorcycle club and upheld the lower court’s finding that the club did not have to forfeit its collective membership marks. United States v. Mongol Nation, Case Nos. 19-50176; -50190 (9th Cir. Jan. 6, 2023) (Ikuta, Forrest, Thomas, JJ.)

Mongol Nation is an unincorporated association comprised of Mongols Gang members and, per the district court, is “a violent, drug trafficking organization.” After a jury found Mongol Nation guilty of both substantive and conspiracy violations of the Racketeer Influenced and Corrupt Organizations (RICO) Act, the US government sought forfeiture of Mongol Nation’s rights in its collective membership marks—a category of “intellectual property used to designate membership in an association or other organization”—and specific property displaying those marks. A jury granted both forfeiture requests, but the district court granted forfeiture only of specific tangible property, not the marks themselves. The district court cited the First and Eighth Amendments: The First protected Mongol members’ rights to display their marks, and the Eighth prohibited the disproportionate remedy of forfeiture of marks that have “immense tangible” value to Mongol members. The government then filed another forfeiture application proposing that Mongol Nation forfeit its exclusive rights in the marks, meaning that Mongol Nation could not prevent others from using them, even in commerce, but that they would not transfer to or vest in the United States. The district court again denied this motion on First and Eighth Amendment grounds.

Both parties appealed, presenting two issues to the Ninth Circuit. Mongol Nation challenged the district court’s jurisdiction to hear the case because Mongol Nation is not a “person” under RICO. The government challenged the district court’s denial of forfeiture of the marks.

The Ninth Circuit summarily dealt with the first issue, noting that Mongol Nation did not properly raise this argument at the district court. The Court was not persuaded by Mongol Nation’s three-part argument that RICO defines an entity to be a “person” only if the entity has a legal interest in property, California only allows unincorporated associations to hold property if the association has a “lawful” purpose, and the indictment describes Mongol Nation as existing for an “unlawful purpose.” The Court found that the association misstated the indictment allegations, which said Mongol Nation’s purposes were “not limited to” the enumerated unlawful ones. Thus, because this argument was not properly preserved and because the RICO “person” definition did in fact encompass Mongol Nation, the Court found that the district court properly exercised jurisdiction.

The Ninth Circuit also affirmed the district court on the forfeiture issue, albeit for different reasons. Without reaching the district court’s First or Eighth Amendment logic, the Ninth Circuit stated that “RICO’s plain text” made the government’s forfeiture request “a legal impossibility.” The Court explained that, following a criminal conviction, a statute must enable property forfeiture. RICO does have such a penalty provision that encompasses [...]

Deleting Goods from Registration Subject to Cancellation During Audit May Result in Adverse Judgment

by Eleanor B. Atkins | Jan 26, 2023 | Trademarks

The Trademark Trial & Appeal Board (Board) addressed, for the first time, whether the deletion of goods and services as a result of a post-registration audit during a cancellation proceeding triggers Trademark Rule 2.134 and found that it does. The Board required the respondent to show cause as to why its deletion of certain goods from the challenged registration should not result in an adverse judgment. Ruifei (Shenzhen) Smart Technology Co., Ltd. v. Shenzhen Chengyan Science and Technology Co., Ltd., Cancellation No. 92077931 (TTAB Jan. 12, 2023) (Lykos, Lynch, Larkin, ATJ)

Ruifei (Shenzhen) Smart Technology petitioned to cancel a trademark that was registered to Shenzhen Chengyan Science and Technology Co., Ltd. (Chengyan) based on abandonment and fraud. Ruifei thereafter filed a motion for leave to amend its pleadings and concurrently filed a motion for partial summary judgment. Finding that Chengyan did not contest the motion for leave to amend, the Board granted Ruifei’s motion and accepted the proposed amended petition to cancel. The summary judgment motion, however, was deferred, pending Chengyan’s response to the instant order.

After the cancellation proceeding was initiated, Chengyan filed a Section 8 Declaration of Use in connection with the contested registration and received a post-registration office action audit. In response to the audit, Chengyan deleted some of the goods from the contested registration’s identification.

Ruifei mentioned the amendment to the contested registration in its motion for partial summary judgment. The Board, having been made aware of the deletion of goods, held that the amendment raised new issues requiring Chengyan’s input before it could consider the motion for partial summary judgment.

Without the written consent of a petitioner, a respondent’s deletion of goods or services from a registration subject to a pending cancellation action typically would result in judgment against the respondent under Trademark Rule 2.134. The purpose of this rule is to prevent respondents in cancellation proceedings from avoiding judgment by cancelling certain goods or services to render the cancellation action moot.

Trademark Rule 2.134(b) provides respondents with the opportunity to explain why certain goods or services were cancelled under Section 8 to avoid judgment being entered against them:

After the commencement of a cancellation proceeding, if it comes to the attention of the . . . Board that the respondent has permitted its involved registration to be cancelled under section 8 . . . an order may be issued allowing respondent . . . to show cause why such cancellation . . . should not be deemed to be the equivalent of a cancellation by request of respondent without the consent of the adverse party and should not result in entry of judgment against respondent.

The Board had not previously considered a situation in which goods or services were deleted as a result of a post-registration audit but held that the “same concerns . . . and [] policies underlying Trademark Rule 2.134(b) apply.” Accordingly, the Board granted Chengyan 20 days to file a response showing why its deletion of certain goods should not [...]

Bursting the Bubble on Prosecution Delays

by Christopher M. Bruno | Jan 26, 2023 | Patents

Addressing a case where a patent owner filed hundreds of applications as part of a strategy to maintain extraordinarily lengthy patent coverage, the US Court of Appeals for the Federal Circuit affirmed a district court’s determination that the patent owner had engaged in a calculated and unreasonable scheme to delay patent issuance. Personalized Media Comms., LLC v. Apple Inc., Case No. 21-2275 (Fed. Cir. Jan. 7, 2023) (Reyna, Chen, JJ.) (Stark, J., dissenting).

The Uruguay Round Agreements Act and General Agreement on Tariff and Trade (GATT) amended the US patent term to 20 years from the effective filing date, instead of 17 years from the issue date. GATT took effect on June 8, 1995. In the months leading up to GATT’s enactment, some would-be patentees seeded patent applications with tremendous disclosures to anchor future applications and obtain the longer pre-GATT term. Practitioners referred to this time period as the GATT bubble. Personalized Media Communications (PMC) submitted 328 GATT bubble applications, from which PMC sought somewhere between 6,000 and 20,000 patent claims. The term of these patents would be 17 years from their issue date instead of 20 years from their priority date.

PMC asserted that Apple’s FairPlay digital rights management software infringed a patent covering a decryption method and won a jury verdict of $330 million. After the verdict, the district court held a bench trial and ultimately found that the patent was unenforceable because of prosecution laches, a doctrine that bars the assertion of patents where the patentee caused unreasonable delay in obtaining the patent, to the detriment of the accused infringer. PMC appealed.

The Federal Circuit affirmed. First, it examined whether the district court had properly concluded that PMC unreasonably delayed. Based on a wide swath of record evidence, all three panel members—Judges Reyna, Chen and Stark—agreed that, like the patentee in Hyatt v. Hirschfeld, PMC had engaged in an intentional scheme to delay patent issuance and extend its monopoly. PMC tried to distinguish its case from Hyatt by arguing that it had developed, with the US Patent & Trademark Office, a consolidation procedure to prioritize review of certain applications. The Court concluded that the structure of the agreement still unreasonably drew out resolution of PMC’s applications, however. The Court also approved of the district court’s reasoning based on the number of applications filed and the introduction of new (albeit narrowing) elements to the claims 16 years after the priority date.

Turning to prejudice, the Federal Circuit concluded that the district court did not act improperly in determining that the delay and improper conduct continued to harm Apple up through the filing of suit in 2015. The Court found that the patent had issued based on a pending claim that PMC did not disclose during PMC-Apple license negotiations and which PMC could quickly get granted and assert against Apple.

Judge Stark dissented, stating that he would conclude that the prejudice Apple faced did not happen during the period in which PMC unreasonably delayed issuance. Judge [...]

PTO Introduces Intellectual Property Identifier Tool

by Amol Parikh | Jan 26, 2023 | Uncategorized

On January 18, 2023, the US Patent & Trademark Office announced the launch of its new Intellectual Property (IP) Identifier tool. This tool is designed for those who are less familiar with IP and assists users in determining whether they have IP and identifies what IP protections are available to support their business, invention or brand. The tool also briefly explains patents, trademarks, copyrights and trade secrets.

The IP Identifier tool comprises two modules: The Basic IP Identifier and the Advanced IP Identifier. The Basic IP Identifier module consists of six questions that allow users to quickly identify the type of IP they should protect. The Advanced IP Identifier module explains the specific types of IP and includes links to additional resources, including how to file an application for protection. A third module, Managing Your IP Assets, is currently under development.

I Know That Brand . . . Or Do I? Reviewing the Eleventh Circuit’s Likelihood of Confusion Analysis

by Kavya Rallabhandi | Jan 26, 2023 | Trademarks

The US Court of Appeals for the Eleventh Circuit reversed and remanded a district court’s summary judgment ruling finding no likelihood that consumers might be confused as to any relationship between competitors operating in the same state, in similar trade channels and using a mark having the same primary word component. The Court held that a reasonable factfinder could determine that there was a likelihood of confusion between the parties’ marks as used in commerce. FCOA LLC v. Foremost Title & Escrow Services LLC, Case No. 19-13390 (11th Cir. Jan. 12, 2023) (Branch, Grant, Tjoflat, JJ.)

FCOA is an insurance company that has been selling and marketing insurance policies using FOREMOST marks since 1952. Foremost is a shell company selling title insurance on behalf of a law firm. Both parties operate in Florida. Seven months after Foremost started using its FOREMOST mark, FCOA sent Foremost a cease-and-desist letter. Foremost disputed the trademark infringement allegations and denied having any knowledge of FCOA or FCOA’s FOREMOST marks. The district court denied FCOA’s summary judgment motion and granted Foremost’s cross-motion for summary judgment, holding that FCOA failed to show a likelihood of confusion between the marks. FCOA appealed.

The Eleventh Circuit reviewed the district court decision de novo. Since there was no dispute that FCOA’s marks were valid, the Court focused its trademark infringement analysis on whether Foremost’s FOREMOST mark was likely to cause consumer confusion. It did so by analyzing its eight likelihood of confusion factors:

Actual confusion is the most important factor in the analysis. The Eleventh Circuit found no evidence that consumers actually confused the parties’ marks in the period between Foremost’s allegedly infringing acts and the lawsuit filing. Therefore, this factor weighed against a likelihood of confusion.
A mark’s strength/distinctiveness is the second most important factor because it analyzes the scope of the mark’s protection. The Eleventh Circuit found that FCOA’s FOREMOST mark was distinctive because, although the word mark in isolation is descriptive, it achieved secondary meaning through consumer recognition and commercial strength. The Court did not find Foremost’s list of likely inactive businesses using FOREMOST to be compelling rebuttal evidence. Therefore, this factor weighed in favor of a likelihood of confusion.
Similarity of the marks is relevant because the likelihood of confusion increases as the marks share more overall similarities. The Eleventh Circuit focused on the distinctive parts of the marks, noting that both logos feature FOREMOST prominently in bold, have two lines of text and are similarly centered and stylized. While there are differences in the logo fonts and colors, the Court determined that this factor still weighed in favor of confusion because consumers are unlikely to be discerning about these differences.

Similarity of the products that the marks represent is relevant in determining whether consumers think the marks originate from a single source. The Eleventh Circuit determined that [...]

That Stings: Consent to Jurisdiction Must Be Effective at Filing to Invoke Fed. R. Civ. P. 4(k)(2)

by Joshua Revilla | Jan 19, 2023 | Patents

The US Court of Appeals for the Federal Circuit, on petition for writ of mandamus, vacated the district court’s transfer order and remanded the transfer to be considered under the clarified parameters of Fed. R. Civ. P. 4(k)(2) and 28 U.S.C. § 1404. In re: Stingray IP Solutions, LLC, Case No. 2023-102 (Fed. Cir. Jan. 9, 2023) (Lourie, Taranto, Stark, JJ.)

Stingray filed patent infringement suits in the US District Court for the Eastern District of Texas against TP-Link, a company headquartered and organized in China. TP-Link moved to transfer to the Central District of California (CDCA) under 28 U.S.C. § 1406 citing an alleged lack of personal jurisdiction that Rule 4(k)(2) did not cure because TP-Link would be amenable to suit in the CDCA. TP-Link also moved for transfer under 28 U.S.C. § 1404(a). The district court granted the motion to transfer under § 1406 based on the rationale that TP-Link was amenable to suit in the CDCA and relying on affirmative reservations made by TP-Link that the CDCA had proper jurisdiction and venue. The district court denied TP-Link’s § 1404(a) motion as moot following the transfer. Stingray filed a mandamus petition asking the Federal Circuit to determine whether TP-Link’s unilateral, post-suit consent to personal jurisdiction in another state defeated application of Rule (4)(k)(2).

The Federal Circuit first determined that mandamus review was appropriate in this case in order to resolve the question of whether a defendant can defeat personal jurisdiction under Rule 4(k)(2) by unilaterally consenting to suit in a different district, a jurisdictional question that has divided district courts. Some district courts have held that personal jurisdiction cannot be established under Rule 4(k)(2) if a defendant states that it is amenable to suit in another state, while others have concluded that defendants must do more than simply designate an alternative forum in order to avoid application of Rule 4(k)(2).

Rule 4(k)(2) was originally introduced to close a loophole where non-resident defendants without minimum contact with any individual state suitable to support jurisdiction, but with sufficient contacts with the United States as a whole, were able to escape jurisdiction in all 50 states. The rule essentially provided that under federal claims, serving a summons or filing a waiver of service could establish personal jurisdiction if the defendant was not subject to a state’s general jurisdiction and exercising jurisdiction would be consistent with the US Constitution and laws.

Here, the case focused on the “negation requirement” of Rule 4(k)(2) where the defendant is not subject to any jurisdiction of a state court. This case addressed the question of whether a defendant’s post-suit, unilateral consent to suit in another state prevents the requirement that a defendant is not subject to a state’s general jurisdiction from being satisfied.

The Federal Circuit determined that the “negation requirement” requires defendants to identify a forum where jurisdiction would have been proper at the time of filing, regardless of consent. The Court determined that therefore a defendant cannot use a “unilateral statement of consent” to [...]

Absent Expressed Rationale of Obviousness, Federal Circuit Calls for Do-Over

by Anisa Noorassa | Jan 19, 2023 | Patents

The US Court of Appeals for the Federal Circuit reversed a ruling by the Patent Trial & Appeal Board (Board) where, on appeal, the US Patent & Trademark Office’s (PTO) rationale for sustaining the Board’s obviousness rejection did not reflect “the reasoning or findings the Board actually invoked.” In Re Google, LLC, Case No. 22-1012 (Fed. Cir. Jan. 9, 2023) (Moore, C.J., Lourie, Prost, JJ.)

Google’s patent application covers a method of filtering search results to display age-appropriate results using a “content rating score” in combination with a predetermined threshold value to determine which results will be presented. The application discloses several ways that the threshold value can be calculated, including using the length of the search query as a proxy for the age of the user, with longer queries being associated with older users and leading to a lower threshold score (allowing more mature content to be shown).

The application received a final rejection from the examiner, who asserted that the claims would have been obvious under 35 U.S.C. § 103 based on two prior art references, Parthasarathy and Rose. Parthasarathy disclosed a method to determine a content score to use for ranking results, while Rose disclosed a method to assign result importance based on query length. The examiner argued that it would be obvious to combine Rose and Parthasarathy to achieve the claimed method that recited a “predetermined threshold value” based on the number of words in a query. The examiner acknowledged that Parthasarathy did not disclose a threshold based on a number of words but found that Rose did, citing Rose’s modified relevance-ranking algorithm. He reasoned that it would have been obvious to combine Rose and Parthasarathy to achieve the claimed threshold because “analyzing a query for determining the query length and using the query length as a threshold is very well known in the art and doing so would further provide for assigning weight to a long or a short query for retrieving documents.” Google appealed the examiner’s decision to the Board, which affirmed the examiner’s rejection and adopted the examiner’s findings. Google appealed to the Federal Circuit.

On appeal, the PTO argued that because there were only two ways a person of ordinary skill in the art could modify Parthasarathy’s threshold to incorporate Rose, either of the modifications would have been obvious. However, the Federal Circuit found that this argument was not supported by the Board’s decision. The Court explained that while the Board did conclude that modifying Parthasarathy’s threshold to take into account the length of the query would have been obvious, the Board did not provide any detail as to how that would be achieved. In the absence of specific fact-based findings by the Board, the Court explained that it could not adopt the PTO’s argument, which rested on facts not found in the Board’s decision. A ruling relying on these facts would have resulted in a violation of basic administrative law principles since a court may only uphold an agency action on [...]

Dictionaries Don’t Know Best: The Intrinsic Record Prevails (Again)

by Courtney Seams | Jan 19, 2023 | Patents

The US Court of Appeals for the Federal Circuit addressed the tension between the intrinsic and extrinsic record in claim construction, holding that the intrinsic record should be relied on first. The Court therefore reversed a district court finding of indefiniteness based on dictionary definitions and expert testimony. Grace Instrument Industries, LLC v. Chandler Instruments Company, LLC, Case Nos. 21-2370; -2370 (Fed. Cir. Jan. 12, 2023) (Chen, Cunningham, Stark, JJ.)

Grace owns a patent for a liquid pressurized viscometer used commonly to test the viscosity of drilling fluid that is used to drill oil wells. Grace’s viscometer uses an “enlarged chamber” between a lower chamber and a pressurization fluid inlet. According to the patent specification, this enlarged chamber was designed to reduce the measurement error in prior viscometer models that was caused by the mixing of sample fluid and pressurization fluid or by friction emanating from a seal in the viscometer. Within the lower chamber of the patented viscometer, there is a rotor having a “means for driving said rotor to rotate.”

Grace sued Chandler, claiming that Chandler infringed Grace’s viscometer patent. During claim construction, the district court found that the term “enlarged chamber” was indefinite, and that because it was a “term of degree,” it must be compared against something objective. The district court entered its final judgment in favor of Chandler. Grace appealed.

The Federal Circuit reversed, explaining that the “enlarged chamber[’s]” size did not need to be compared against any baseline object, but rather needed to be “large enough to accomplish a particular function.” The Court relied on the specification, which explained that the viscometer described in the patent reduced the mixing of sample fluid and pressurization fluid that was common in older viscometer models by using an “enlarged chamber.” The Court also cited the prosecution history, where the applicant explained that the invention solved a “long lasting problem” by reducing the measurement error caused by the friction of the seal or mixing of the fluids in older viscometer designs. Thus, the Court reasoned that a person of ordinary skill in the art would understand that the “enlarged chamber” must be large enough to prevent the mixing of the pressurization fluid and sample fluid to avoid the measurement errors associated with prior art viscometers.

Chandler argued that the term “enlarged chamber” was not a term of art. The Federal Circuit agreed but explained that “the intrinsic record sufficiently guides a skilled artisan as to the meaning of the term” as used in the patent. The Federal Circuit found that the district court erred in relying on a dictionary definition (extrinsic evidence) to contradict the meaning of the term found within the intrinsic record. The specification’s instructions for the meaning of a claim term should prevail over extrinsic evidence. Rebuffing Chandler’s argument, the Court explained that the specification does not need to explicitly define the claim term to govern the interpretation of that term.

The Federal Circuit remanded the case to the district court to reconsider indefiniteness in [...]
