ANDA Filing Alone Insufficient for Induced Infringement of Method Patent

The US Court of Appeals for the Federal Circuit upheld a district court’s findings of invalidity and noninfringement in a Hatch-Waxman case involving two sets of method patents directed to modulating dosages of pirfenidone, a drug used to treat idiopathic pulmonary fibrosis (IPF). The Court found that the first set of patents were obvious over the prior art and standard medical practice, while the second set were not directly infringed in light of actual physician prescription practice. Genentech, Inc. v. Sandoz Inc., Case No. 22-1595 (Fed. Cir. Dec. 22, 2022) (Newman, Lourie, Prost, JJ.) (Newman, J., dissenting).

Sandoz submitted two abbreviated new drug applications (ANDAs) for approval to market a generic version of pirfenidone, which Genentech sells under the brand name Esbriet®. Genentech sued Sandoz under the Hatch-Waxman Act, asserting that Sandoz’s generic version would induce infringement of two sets of patents: one directed to modifying dosages of pirfenidone in patients with abnormal liver biomarkers (LFT patents), and the other directed to avoiding adverse interactions in patients also taking fluvoxamine (DDI patents).

The LFT patents are directed to methods of administering pirfenidone to a patient who has exhibited Grade 2 abnormalities in liver function biomarkers alanine transaminase (ALT) and/or aspartate transaminase (AST) in response to pirfenidone. The LFT patents generally recite the following administration options:

  • Temporarily reducing the dose before returning to the full dose
  • Maintaining the full dose
  • Reducing the dose
  • Temporarily discontinuing pirfenidone before returning to the full dose
  • Temporarily discontinuing pirfenidone before returning to a reduced dose.

Sandoz’s proposed label included a “Dosage Modification due to Elevated Liver Enzymes” section, which stated that if a patient exhibits grade 2 elevations of ALT and/or AST, “[t]he full daily dosage may be maintained, if clinically appropriate, or reduced or interrupted (e.g., until liver chemistry tests are within normal limits) with subsequent re-titration to the full dosage as tolerated.” Genentech argued that these instructions constituted induced infringement of the LFT patents. The district court disagreed and held that the LFT patents were obvious over the prior art and standard medical practice and that the defendant would not induce infringement because the labels “merely described” the infringing uses but did not recommend them.

The DDI patents are directed to methods for avoiding adverse interactions between pirfenidone and fluvoxamine and generally involve the steps of discontinuing fluvoxamine or modifying the dose of pirfenidone and continuing fluvoxamine. Sandoz’s proposed label warned of the adverse interactions between pirfenidone and fluvoxamine and stated that fluvoxamine should be discontinued prior to administering pirfenidone or the dose of pirfenidone should be reduced. Genentech similarly argued that these instructions constituted induced infringement of its DDI patents, but the district court held that there was insufficient evidence for infringement because Genentech had not shown that a patient would actually be prescribed both pirfenidone and fluvoxamine in practice.

Genentech appealed the district court’s holdings with respect to both the LFT and DDI patents.

LFT Patents

The Federal Circuit first observed that “varying doses in response to the occurrence [...]

Tag, You’re It: Sanctions Award Must Reflect Violative Conduct

The US Court of Appeals for the Federal Circuit determined that an accused infringer was entitled to a new trial relating to validity issues but still faced sanctions for its continuous disregard of its discovery obligations. ADASA Inc. v. Avery Dennison Corp., Case No. 22-1092 (Fed. Cir. Dec. 16, 2022) (Moore, Hughes, Stark, JJ.)

ADASA owns a patent relating to methods and systems for commissioning radio-frequency identification (RFID) transponders. ADASA sued Avery Dennison for patent infringement, alleging that its manufacture and sale of certain RFID tags infringed ADASA’s patent. Both parties sought summary judgment following discovery. Avery Dennison asserted that the patent was ineligible for patent protection under 35 U.S.C. § 101, and ADASA argued that the asserted claims were not anticipated or obvious based on the book RFID for Dummies. The district court granted ADASA’s motion on validity and denied Avery Dennison’s motion for patent ineligibility. Prior to trial, ADASA moved in limine to exclude Avery Dennison’s damages expert’s testimony related to certain licenses, and the district court granted the motion.

At trial, ADASA entered licenses into evidence as part of its damages case and alleged that they reflected lump-sum agreements to practice the asserted patent. The district court declined to include a jury instruction on lump-sum damages and a lump-sum option on the verdict form, observing that Avery Dennison’s expert had not offered a lump-sum damages opinion and concluding that the licenses alone were insufficient for the jury to award lump-sum damages. The jury returned an infringement verdict and awarded ADASA a running royalty of $0.0045 per infringing RFID tag, which resulted in an award of $26.6 million.

In its post-trial motions, Avery Dennison moved for a new trial, arguing it was reversible error for the district court to exclude its damages expert’s testimony and to decline to provide a jury instruction for a lump-sum damages award. Before the district court ruled on its motion, Avery Dennison revealed to ADASA that it had discovered additional previously undisclosed RFID tags in its databases. A subsequent investigation determined that the number of undisclosed tags was more than two billion. Avery Dennison agreed to pay an additional $9.5 million in damages, which corresponded to the royalty rate determined by the jury. ADASA subsequently moved for sanctions. The district court award $20 million in sanctions after finding that Avery Dennison had engaged in protracted discovery failures and a continuous disregard for the seriousness of the litigation and its expected obligations. The sanctions award corresponded to a $0.0025 per-tag rate applied to both the adjudicated and late-disclosed tags. Avery Dennison appealed.

Avery Dennison challenged the district court’s summary judgment rulings, its denial of a new trial and its imposition of sanctions. The Federal Circuit affirmed the district court’s patent eligibility determination, finding that the patent “is directed to a specific, hardware-based RFID serial number data structure designed to enable technological improvements to the commissioning process,” which “is not a mere mental process,” and concluded that the claim was directed to patent-eligible subject matter.

Bad Connection: Claim Construction Argument without Explanation Given No Weight

The US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board (Board) obviousness decision after finding that the patent owner failed to explain how its cited extrinsic evidence supported its proposed claim construction. Uniloc 2017 LLC v. Netflix, Inc., Case No. 21-2085 (Fed. Cir. Dec. 15, 2022) (Dyk, Taranto, Hughes, JJ.) (nonprecedential).

Uniloc owns a patent directed to a “more efficient” method for encoding videos by only coding at the pixel level when necessary and, where possible, reusing code for macroblocks in the background area. Netflix petitioned for inter partes review of several claims in Uniloc’s patent. The Board ultimately found the claims unpatentable as obvious. Uniloc appealed.

Uniloc argued that the Board erred in its claim construction of a limitation that required “dividing the stationary background region and the object region from an inputted video in a macroblock-by-macroblock basis by using a difference between the previous frame and the current frame.” The dispute before the Federal Circuit was whether the “macroblock-by-macroblock basis” required that the act of dividing be done macroblock-by-macroblock, as urged by Uniloc, or whether the dividing resulted in separate macroblock-based regions, as urged by Netflix and found by the Board. The Court concluded that Netflix and the Board were correct.

The Federal Circuit first addressed the intrinsic record, finding that it was ambiguous as to the meaning of “macroblock-by-macroblock basis.” Although the claim language supported either interpretation, Uniloc’s argument would require the Court to read language into the claim that was “simply not there.” The specification did not clarify the claim construction issue either. Although Uniloc pointed to one example where the dividing step occurred one macroblock at a time, the Court stated that it did not limit claim language to examples used in the specification. Lastly, the Court explained that the portions of the specification describing the purpose of the invention and avoiding problems in the prior art also failed to clarify the meaning of the macroblock-by-macroblock basis. Because the purpose was merely to make coding more efficient and avoid dividing at the pixel level, either interpretation could apply.

Relatedly, the Federal Circuit rejected Netflix’s argument that Uniloc forfeited the arguments on appeal related to the portions of the specification explaining the purpose of the claimed invention and how it purportedly solved problems in the prior art. The Court explained that the forfeiture doctrine does not “preclude a party from proffering additional or new supporting arguments, based on evidence record, for its claim construction.” Here, Uniloc “merely cited additional support in the specification to support the same argument it had always made” related to the macroblock-by-macroblock basis.

The Federal Circuit next addressed the extrinsic evidence and agreed with the Board’s decision that a “macroblock-by-macroblock basis” required dividing results in separate macroblock-based regions. Uniloc’s only extrinsic evidence was a dictionary definition of “basis,” and Uniloc offered no additional expert evidence to explain technological facts or usage in the field that would support its interpretation. In contrast, Netflix provided expert testimony and [...]

Full Speed Ahead: District Court Entitled to Explore Litigation Funding Arrangements

The US Court of Appeals for the Federal Circuit denied a patent owner’s mandamus petition, clearing the way for a district court to probe who is funding the patent owner’s infringement litigation. In re Nimitz Techs. LLC, Case No. 23-103 (Fed. Cir. Dec. 8, 2022) (Lourie, Reyna, Taranto, JJ.) (per curiam) (nonprecedential).

Nimitz filed a complaint for patent infringement against Buzzfeed in the US District Court for the District of Delaware. The case was assigned to Chief Judge Connelly. Judge Connelly has two standing orders that require parties to disclose third-party litigation funders and the name of every individual and corporation with a direct or indirect ownership interest in the party. Nimitz filed a disclosure statement identifying Mark Hall as the sole owner and LLC member of Nimitz, and a statement representing that Nimitz has not entered any arrangement with third-party funders.

The district court later became aware that an entity called IP Edge was arranging assignments of patents to various LLCs that were plaintiffs in other actions before the district court. Based on the review of the documents in the other cases, it appeared to the district court that Hall had a connection with IP Edge. The district court ordered Hall and Nimitz’s counsel to appear at a hearing. During the hearing, the district court explored the relationship between Nimitz and an entity called Mavexar. After the hearing, the district court ordered production of communications between Hall, Mavexar and IP Edge, and communication and documents relating to the formation of Nimitz, Nimitz’s assets, Nimitz’s potential scope of liability resulting from the acquisition of the patent, the settlement or potential settlement of the cases and the prior evidentiary hearing. The district court also ordered production of monthly bank statements from Nimitz. Nimitz appealed to the Federal Circuit by filing a petition for writ of mandamus seeking an order vacating the district court’s order.

The Federal Circuit initially stayed the district court’s order pending the Court’s decision. While the mandamus petition was pending, the district court issued a memorandum explaining that the records sought in its prior order were relevant to addressing several concerns, including the following:

  • Compliance with the Rules of Professional Conduct
  • Compliance with the district court’s orders
  • Determining whether real parties in interest other than Nimitz, such as Mavexar and IP Edge, were hidden from the Court and the defendants
  • Determining whether those real parties in interest perpetrated a fraud on the district court by fraudulently conveying to a shell LLC the patent-in-suit and filing a fictitious patent assignment with the US Patent & Trademark Office designed to shield those parties from the potential liability they would otherwise face in asserting the patent in litigation.

Nimitz had argued that the district court’s order was improper because it would require disclosure of highly confidential litigation materials, including material protected by the attorney-client privilege and work-product immunity. In its decision on mandamus, the Federal Circuit rejected that argument, finding that the district court order made clear that Nimitz [...]

Applying Collateral Estoppel in IPRs

The US Court of Appeals for the Federal Circuit considered whether a dependent claim invalidated by collateral estoppel also invalidates its parental independent claim. Google LLC v. Hammond Devel. Int’l, Inc., Case No. 21-2218 (Fed. Cir. Dec. 8, 2022) (Moore, C.J.; Chen, Stoll, JJ.)

The dispute began when Hammond Development sued Google, alleging that Google infringed several of Hammond’s patents on automated voice response systems. In response, Google filed multiple inter partes reviews (IPRs), one of which targeted Hammond’s ’483 patent. In that proceeding, the Patent Trial & Appeal Board (Board) held that all claims of the ’483 patent were obvious. Hammond did not appeal the decision in this IPR, which then became final, but only after Google filed an IPR against another of Hammond’s patents—the ’816 patent. The ’816 and ’483 patents are in the same family and share the same specification. In the later-filed IPR, the Board found claims 14 through 19 of the ’816 patent nonobvious and patentable. Google appealed.

Claim 14 is an independent claim and claim 18 depends from it. The parties agreed that the patentability of both claims rose and fell together. On appeal to the Federal Circuit, Google argued that claim 18 was invalid under the doctrine of collateral estoppel based on the prior art that rendered claim 18 of the ’483 patent invalid.

A party seeking to invoke collateral estoppel must show the following:

  • The issue is identical to one decided in the first action.
  • The issue was actually litigated in the first action.
  • Resolution of the issue was essential to a final judgment in the first action.
  • The party against whom collateral estoppel is being asserted had a full and fair opportunity to litigate the issue in the first action.

Because the parties had agreed that all but the first of the elements of collateral estoppel were met, collateral estoppel would apply if the issues of patentability were identical between the adjudicated and unadjudicated claims. The Federal Circuit found that slight differences in the claim language of the involved patents were immaterial because they related only to the number of application servers, and Google’s expert had credibly testified that distributing software applications across multiple servers was well known in the art and obvious. Hammond did not mount a substantive challenge to the expert evidence. As the Court noted, “collateral estoppel may apply even if the patent claims ‘use slightly different language to describe substantially the same invention,’ so long as ‘the differences between the unadjudicated patent claims and adjudicated patent claims do not materially alter the question of invalidity.’”

Google also attacked the validity of independent claim 14 of the ’816 patent. Although Google’s attack against claim 14 was based on a different combination of references (as compared to claim 18), the Federal Circuit apparently applied collateral estoppel to find claim 14 invalid as well, citing an agreement between the parties that “if claim 18 is unpatentable, then independent claim 14 is as well.”

Finally, Google argued that dependent [...]

Game Over when Expert Fails to Use Correct Claim Construction

The US Court of Appeals for the Federal Circuit concluded that a district court did not abuse its discretion in striking expert testimony where the testimony did not rely on an agreed and court-adopted claim construction. Treehouse Avatar LLC v. Valve Corp., Case No. 22-1171 (Fed. Cir. Nov. 30, 2022) (Lourie, Reyna, Stoll, JJ.)

Treehouse owns a patent that describes a “method of collecting data from an information network in response to user choices of a plurality of users navigating character-enabled network sites on the network.” Valve owns two video games. To play the games, a user downloads the software onto a computer. The software contains data, images, sounds, text and characters. Treehouse sued Valve for patent infringement based on the operation of the accused video games. During the district court proceeding, both parties adopted the interpretation of the term “character enabled (CE) network sites” (CE limitation) that the Patent Trial & Appeal Board reached in a previous inter partes review. Despite the agreed-upon and court-adopted construction for the CE limitation, Treehouse’s infringement expert submitted a report that applied plain and ordinary meaning.

Valve filed a motion to strike portions of the expert’s testimony that relied on the plain and ordinary meaning of the term. Valve also filed a motion for summary judgment of noninfringement while this motion to strike was pending. Treehouse’s opposition appeared to concede that Valve was entitled to summary judgment if Valve’s motion to strike was granted, stating that “assuming that [the expert’s] testimony is not stricken, this portion of Valve’s motion should be denied.” The district court struck every paragraph of the expert’s report that Valve requested and granted Valve summary judgment of noninfringement. Treehouse appealed.

The Federal Circuit found that the district court did not abuse its discretion in striking portions of Treehouse’s expert report that did not address the claim construction of the CE limitation agreed upon by the parties and the district court. Treehouse argued that an expert report that does not recite an agreed claim construction remains admissible as long as the opinions expressed in the report are not inconsistent with that construction. The Court rejected Treehouse’s argument, explaining that “the grant of a motion to strike expert testimony is not improper when such testimony is based on a claim construction that is materially different from the construction adopted by the parties and the court.” The Court further explained that when a trial court has adopted a construction that the parties requested and agreed upon, any expert theory that does not rely upon that agreed-upon construction is suspect. The Court thus concluded that the district court did not abuse its discretion in striking the portions of the expert’s report that applied a “plain and ordinary meaning” of the CE limitation instead of the parties’ agreed-upon construction. In the absence of any admissible expert testimony by Treehouse regarding infringement of the CE limitation, the Court found that the district court properly granted summary judgment of noninfringement.

On the Border of Art and Trademark: First Amendment Trumps the Lanham Act

The US Court of Appeals for the Eleventh Circuit weighed trademark rights against free speech considerations and found that the First Amendment protected use of an artistic work that was not deliberately misleading. MGFB Properties Inc. et al. v. 495 Productions Holdings LLC et al., Case No. 21-13458 (11th Cir. Nov. 29, 2022) (Luck, Brasher, Hull, JJ.) (Brasher, J., concurring).

The suit was brought by MGFB Properties, Flora-Bama Management and Flora-Bama Old S.A.L.T.S. (collectively, the plaintiffs). The plaintiffs own and operate the Flora-Bama Lounge, Package and Oyster Bar on the Florida-Alabama border. The lounge has been in business since 1964 and is well known in the region. The plaintiffs registered their trademark FLORA-BAMA in 2013.

Viacom and 495 Productions (collectively, the defendants) produce reality television series, such as the hit 2009 series Jersey Shore. In light of Jersey Shore’s success, the defendants produced several spinoffs. In 2016 the defendants decided to develop a new spinoff based on “southern beach culture” and chose the term “Floribama” to describe “relaxing Florida beaches with the down-home Southern vibe of Alabama.” The defendants were aware of the name’s connection to the Florabama Lounge but used the term regardless to identify a specific stretch of the Gulf Coast (the Florida and Alabama coasts) and inserted dialogue into the show to explain the term. The show’s logo emphasized its connection to the Jersey Shore franchise:

The plaintiffs argued that the defendants’ use of “Floribama” was a violation of the Lanham Act and caused unfair confusion and damage to their brand. The district court granted summary judgment for the defendants. Plaintiffs appealed.

The Eleventh Circuit upheld the district court’s judgment that the defendants’ First Amendment rights as the creators of an artistic work outweighed the plaintiffs’ interest in their trademark and in avoiding confusion around their brand: “[c]reative works of artistic expression are firmly ensconced within the protections of the First Amendment.” In reaching its outcome, the Court applied the 1989 Rogers v. Grimaldi test.

Under the first prong of the Rogers test, “an artistically expressive use of a trademark will not violate the Lanham Act unless the use of the mark has no artistic relevance to the underlying work whatsoever.” Here, the Eleventh Circuit found that the defendants’ use of the term “Floribama” to describe the geographic area featured in Floribama Shore and the subculture of that region satisfied the first element of the Rogers test. The Court held that it was sufficient for the defendants’ use of “Floribama” to be relevant to their show, even if the term was not “necessary” to production of the show.

Under the second prong of the Rogers test, the Eleventh Circuit found that the defendants’ use of “Floribama” was not explicitly misleading “as to the source or content of the work” such [...]

Words Matter: Court Sides with Translation Company in Insurance Coverage Dispute

The US Court of Appeals for the First Circuit concluded that a company’s general liability insurer was obligated to provide coverage for legal fees incurred in fending off a trade secret and defamation lawsuit brought by a competitor. Lionbridge Tech., LLC v. Valley Forge Ins. Co., Case No. 21-1698 (1st Cir. Nov. 21, 2022) (Kayatta, Selya, Thompson, JJ.)

Lionbridge and TransPerfect are competitors in the language-translation industry. TransPerfect sued Lionbridge for misappropriation of trade secrets and defamation. TransPerfect alleged that Lionbridge concocted a scheme through its corporate owner to feign interest in acquiring TransPerfect and, through this scheme, improperly gained access to TransPerfect’s trade secrets, which could be used to poach TransPerfect’s customers and otherwise undermine TransPerfect’s business.

Shortly after the lawsuit was filed, Lionbridge informed its liability insurance carrier, Valley Forge, about the litigation. Valley Forge initially indicated that it would provide Lionbridge with coverage for legal costs associated with the litigation. Valley Forge subsequently disputed the requested coverage based on both the reasonableness of the fees incurred and the nature of the suit. Lionbridge filed suit against Valley Forge seeking full coverage from Valley Forge for its defense costs. The dispute centered on whether the fees incurred could be considered injury arising out of “[o]ral or written publication, in any manner, of material that slanders or libels a person or organization or disparages a person’s or organizations goods, products, or services,” as provided by Lionbridge’s insurance policy. The district court granted summary judgment in favor of Valley Forge, finding that Valley Forge did not owe Lionbridge a duty to defend under the relevant policy provisions and exclusions. Lionbridge appealed.

The First Circuit reversed, explaining that an insurer’s duty to defend depends on whether the allegations in the underlying litigation are reasonably susceptible to an interpretation that the policy provisions apply. The focus of the inquiry is the source of the injury, not any specific theories of liability set forth in the underlying complaint. The Court explained that this inquiry required a comparison of the allegation made in the underlying litigation against the insurance policy provisions.

After analyzing the underlying complaint against the insurance policy, the First Circuit determined that the policy provisions applied because the allegations “roughly sketch[ed]” an injury arising from a defamation claim. TransPerfect’s claims were rooted in alleged reputational harm to its business, which fit within the relevant provision. The Court noted that complete overlap between the policy provisions and the claims was not required.

The First Circuit next considered whether any policy coverage exclusions applied to preclude coverage. The relevant exclusions fell into two buckets:

  • Injuries caused by an insured with direct knowledge that its actions would inflict injury, or injuries arising out of an oral or written publication that the insured knows is false
  • Trade secret misappropriation.

Valley Forge carried the burden of proving that either or both categories of exclusions applied. The Court concluded that the first category did not apply because Valley Forge failed to show that all allegations [...]

Construing the Construction: Federal Circuit Chips Away at IPR Win

Addressing claim construction issues in inter partes review (IPR) proceedings before the Patent Trial & Appeal Board (Board), the US Court of Appeals for the Federal Circuit affirmed an obviousness finding as to some claims but reversed and remanded an obviousness finding as to another claim because of a claim construction error. VLSI Technology LLC v. Intel Corporation, Case Nos. 21-1826, -1827, -1828 (Fed. Cir. Nov. 15, 2022) (Chen, Bryson, Hughes, JJ.)

VLSI owns a patent directed to a technique for alleviating the problems of defects caused by stress applied to bond pads of an integrated circuit. Bond pads are a portion of an integrated circuit that sit above interconnected circuit layers and are used to attach the chip to another electronic component, such as a computer or motherboard. When a chip is attached to another electronic component, forces are exerted on the chip’s bond pad, which can result in damage to the interconnect layers. The patent discloses improvements to the structures of an integrated circuit that reduce the potential for damage to the interconnect layers when the chip is attached to another electronic component while also permitting each of the layers underlying the pad to be functionally independent in the circuit.

VLSI filed suit against Intel alleging infringement of the patent. During claim construction, the district court construed the claim term “force region” to mean a “region within the integrated circuit in which forces are exerted on the interconnect structure when a die attach is performed.” Before the district court’s construction but after the suit was filed, Intel filed petitions for IPR of the patent and advocated in its petitions for the same construction of “force region” that the district court ultimately adopted.

VLSI did not contest Intel’s construction, but it later became apparent that the two parties disagreed over the meaning of “die attach,” which formed part of the construction. Intel argued that the term “die attach” refers to any method of attaching a chip to another electronic component, including a method known as wire bonding, which was taught by a prior art reference included in Intel’s petitions. VLSI argued that the term refers to a method of attachment known as “flip chip” bonding and does not include wire bonding. In the Board’s final written decisions, it did not address the term “die attach,” but found that “force region” was not limited to flip chip bonding and subsequently found the challenged claims invalid as obvious. The Board also construed a second disputed term “used for electrical interconnection not directly connected to the bond pad,” which is recited in only one claim of the patent, in favor of Intel, and subsequently found that claim unpatentable. VLSI appealed.

On appeal, VLSI raised a number of procedural and substantive challenges to the Board’s construction of the two disputed terms. VLSI argued that the Board failed to acknowledge and give appropriate weight to the district court’s construction of “force region.” The Federal Circuit dismissed this argument, as there was ample evidence in [...]

Court Uncorks New Way to Serve Trademark Complaints

The US Court of Appeals for the Ninth Circuit concluded that Section 1051(e) of the Lanham Act permits a plaintiff in a district court case to serve a complaint against a foreign defendant via the Director of the US Patent & Trademark Office (PTO). San Antonio Winery, Inc. v. Jiaxing Micarose Trade Co., Ltd., Case No. 21-56036 (9th Cir. Nov. 14, 2022) (Siler, Callahan, Thomas, JJ.)

San Antonio Winery is a Los Angeles-based winery best known for its Stella Rosa brand of wines. The winery is owned and operated by the Riboli family. San Antonio has registered the trademarks RIBOLI and RIBOLI FAMILY, which it has used since at least 1998 to market its wines and other products.

Jiaxing is a Chinese company that has sold products using the Riboli name. In 2018, Jiaxing registered the mark RIBOLI for use in connection with articles of clothing and shoes. In 2020, Jiaxing applied to register the mark RIBOLI for use with additional types of products, including wine pourers, bottle stands, containers, cocktail shakers, dishware and various other kitchen and household items.

After learning that Jiaxing was using the Riboli name to sell products in the United States, San Antonio filed a complaint asserting Lanham Act claims for trademark infringement, trademark dilution and false designation of origin, as well as related state-law claims. San Antonio also sought an injunction prohibiting Jiaxing from using the RIBOLI mark in connection with its products, an order canceling Jiaxing’s 2018 registration of the RIBOLI mark, and an order either directing Jiaxing to abandon its 2020 application to register RIBOLI for additional uses or prohibiting the PTO from granting the application.

Because Jiaxing is a Chinese company, San Antonio’s service of process was governed by rules for serving parties abroad, such as by the Hague Convention. Concerned with the amount of time it might take to effect service under the Hague Convention, San Antonio instead sought to serve Jiaxing under Section 1051(e) of the Lanham Act, which applies to foreign domiciliaries who apply to register a trademark. Section 1051(e) states that if a trademark applicant is not domiciled in the United States, the applicant may designate the name and address of a person in the United States who may be served with notices or processes in proceedings affecting the mark. If the designated person cannot be found at the address, the notices or processes may be served on the PTO Director.

Seeking to avail itself of Section 1051(e), San Antonio inquired whether the US-based lawyer who had represented Jiaxing in connection with its trademark applications would accept service on Jiaxing’s behalf. When the lawyer did not respond, San Antonio served the district court complaint on the PTO Director, who then sent a letter to Jiaxing confirming service of process was effectuated pursuant to Section 1051(e).

After Jiaxing did not appear to defend itself in the action, San Antonio filed a motion for default judgment. The district court denied the motion on the ground that Jiaxing had not [...]
