Lanham Act Reaches Foreign Defendants’ Extraterritorial Conduct, but Worldwide Injunction Too Broad

The US Court of Appeals for the Tenth Circuit upheld a district court’s injunction barring multiple foreign companies from directly or indirectly using a US remote control manufacturer’s trade dress based on the extraterritorial reach of the Lanham Act. However, the Court narrowed the scope of the worldwide injunction to countries where the US company currently markets or sells its products. Hetronic Int’l, Inc. v. Hetronic Germany GmbH, Case Nos. 20-6057, -6100 (10th Cir. Aug. 24, 2021) (Phillips, J.)

Hetronic International is a US company that manufactures radio remote controls for heavy-duty construction equipment. Hetronic Germany GmbH, Hydronic Steuersysteme GmbH, ABI Holding GmbH, Abitron Germany GmbH and Abitron Austria GmbH (collectively, the Distributers) are foreign companies that have distributed Hetronic’s products—mostly in Europe—for almost a decade. Based on an old research and development agreement between the parties, the Distributors concluded that they, not Hetronic, owned the rights to Hetronic’s trademarks and other intellectual property. The Distributors accordingly reverse-engineered Hetronic’s products and began manufacturing and selling their own copycat products, mostly in Europe. The copycat products were identical to Hetronic’s and were sold under the Hetronic brand and the same product names. Hetronic terminated the parties’ distribution agreements, but the Distributers continued to sell their copycat products. The Distributors attempted to break into the US market, selling several hundred thousand dollars’ worth of products before backing off after Hetronic sued. They then focused their efforts on Europe.

Hetronic sued the Distributors, along with their manager and owner Albert Fuchs, under the Lanham Act. The Distributors moved for summary judgment, arguing that the district court lacked subject matter jurisdiction to resolve the Lanham Act claims because the conduct at issue occurred overseas. The Distributors asserted that Hetronic’s claims had to be dismissed because the Lanham Act applied extraterritorially only if a defendant’s conduct had a substantial effect on US commerce, and the Distributors’ conduct did not. The district court rejected that argument and denied summary judgment.

In a separate proceeding initiated by the Distributors in the European Union, the EU Intellectual Property Office (EUIPO) concluded that Hetronic owned all of the disputed intellectual property. Based on the EUIPO proceeding, the district court applied the doctrine of issue preclusion and granted Hetronic summary judgment on the Distributors’ ownership defense. After an 11-day trial, a jury found that the Distributors had willfully infringed Hetronic’s trademarks and awarded Hetronic more than $100 million in damages, mostly for trademark infringement. The district court also entered a permanent injunction prohibiting the Distributors’ infringing activities worldwide. The Distributors appealed.

On appeal, the Distributors accepted that the Lanham Act can sometimes apply extraterritorially but argued that the Lanham Act did not reach their activity as foreign defendants making sales to foreign consumers. Specifically, the Distributors argued that:

  • The district court erroneously concluded that the Lanham Act applied extraterritorially.
  • The injunction lacked the specificity required by Fed. R. of Civ. Pro. 65.
  • The injunction’s worldwide reach was too broad.

The Distributors challenged the district court’s exercise of personal [...]

Absent Explicit Statutory Language? The American Rule Still Applies

The US Court of Appeals for the Federal Circuit vacated a district court’s award of attorney’s fees under the prevailing party rule but affirmed the district court’s denial of the US Patent & Trademark Office’s (PTO) request for expert witness fees under 35 U.S.C. § 145. Hyatt v. Hirshfeld, Case Nos. 20-2321;–2325 (Fed. Cir. Aug. 18, 2021) (Hughes, J.). The case involved prolific inventor Gilbert Hyatt and the latest chapter in his battles with the PTO.

Mr. Hyatt is known for his prolific patent and litigation filings (including hundreds of extraordinarily lengthy and complex patent applications in 1995 alone) and for often “’adopt[ing] an approach to prosecution that all but guaranteed indefinite prosecution delay’ in an effort to submarine his patent applications and receive lengthy patent terms.” After the PTO denied some of his patent applications, Mr. Hyatt elected to pursue a district court appeal under 35 U.S.C. § 145 to challenge the PTO’s decisions. The district court ordered the PTO to issue some of the patents and awarded Mr. Hyatt attorney’s fees as the prevailing party. The PTO spent millions of dollars examining Mr. Hyatt’s applications and sought, under §145, reimbursement of its expert witness fees from the case. The district court denied the PTO’s request for expert witness fees, holding that its shifting of “[a]ll the expenses of the proceedings” to the applicant does not overcome the American Rule presumption against shifting expert fees. The PTO appealed.

The PTO challenged both the award of attorney’s fees and the denial of expert fees. In an earlier appeal by the PTO, the Federal Circuit held that the PTO correctly asserted prosecution laches as a defense against Mr. Hyatt, which “render[s] a patent unenforceable when it has issued only after an unreasonable and unexplained delay in prosecution that constitutes an egregious misuse of the statutory patent system under a totality of the circumstances.” Accordingly, the Court vacated the district court’s decision ordering the issuance of patents, and in this appeal, the Court vacated the district court’s holding that Mr. Hyatt is entitled to attorney’s fees—since he is no longer the prevailing party—and remanded for further proceedings.

According to the statute, in an action under § 145, “[a]ll the expenses of the proceedings shall be paid by the applicant.” However, the Federal Circuit agreed with the district court that the statutory language was not sufficiently explicit to overcome the presumption against fee-shifting under the American Rule and that litigants pay their own fees “unless a statute or contract provides otherwise.” In doing so, the Court looked at statutory phrasing, dictionary definitions (e.g., Black’s and Webster’s), legislative history, relevant case law and similarly phrased statutes to confirm whether expert fees were specifically and explicitly contemplated as being included by US Congress in the statute. The Supreme Court of the United States’ 2019 NantKwest decision (that “expenses” under §145 does not invoke attorney’s fees with enough clarity to overcome the American Rule) guided the Court’s analysis as did [...]

Greek God or Continent? Defining “Confusing Similarity” under the Anti-Cybersquatting Consumer Protection Act

Examining whether a registered mark and a domain name were confusingly similar under the Anti-Cybersquatting Consumer Protection Act (ACPA), the US Court of Appeals for the 11th Circuit affirmed the district court’s grant of summary judgment in favor of the trademark owner because the mark and domains are nearly identical in sight, sound and meaning. Boigris v. EWC P&T, LLC, Case No. 20-11929 (11th Cir. Aug. 6, 2021) (Marcus, J.) (Newsom, J. dissenting). The registered trademark is “European Wax Center” and the domain names in issue are “europawaxcenter.com” and “euwaxcenter.com.”

EWC runs a nationwide beauty brand titled European Wax Center that offers hair removal services and beauty products and also holds a trademark under the same name. Since 2015, EWC sold cosmetics under the marks “reveal me,” “renew me” and “smooth me.” Bryan Boigris has no direct background related to the production of beauty products, but in April 2016, he claimed an intent to begin selling such products and attempted to register trademarks at the US Patent & Trademark Office (PTO) for “reveal me,” “renew me” and “smooth me,” none of which had been used in commerce before by Boigris. Boigris also registered 11 domain names including, “euwaxcenter.com” and “europawaxcenter.com.” Upon discovery of Boigris’s pending applications, EWC filed for its own trademark applications for “reveal me,” “renew me” and “smooth me” and filed an opposition to Boigris’s pending applications at the Trademark Trial and Appeal Board (TTAB). The TTAB sustained the oppositions.

Boigris elected to contest the TTAB’s decision in district court. Specifically, Boigris sought reversal of the TTAB’s decision and an affirmative declaration that he was entitled to register the disputed marks. EWC counterclaimed for an affirmation of the TTAB’s decision as well as declaratory judgment that it had priority rights in the disputed marks, that Boigris’s use constituted infringement under the Lanham Act, damages and an injunction under the ACPA against Boigris’s use of the two domains, “europawaxcenter.com” and “euwaxcenter.com.” EWC moved for summary judgment on all of its claims, which the district court granted. Boigris appealed the ACPA decision only.

Under the ACPA, a trademark holder must prove that: (1) its trademark was distinctive when the defendant registered the challenged domain name; (2) the domain name is identical or confusingly similar to the plaintiff’s trademark and (3) the defendant registered the domain name with a bad faith intent to profit. Boigris challenged the second element only and did not contest that EWC’s trademarks were distinctive or that he registered the domains in bad faith. Specifically, Boigris argued that the issue of whether or not the “European Wax Center” mark and the “europawaxcenter.com” and “euwaxcenter.com” domains are confusingly similar should have been a question for the jury.

The 11th Circuit affirmed the district court’s ruling, determining that no reasonable jury could conclude that Boigris’s domain names are not confusingly similar to EWC’s mark. The Court acknowledged the difference between the Lanham Act’s traditional multi-factor likelihood of confusion test for trademark infringement and the test for confusing similarity, noting [...]

Third Circuit Orders Second Look at Delays and Disgorgement of Profits

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 [...]

PTO Updates Arthrex Guidance

The US Patent & Trademark Office (PTO) updated its June 29, 2021, interim procedure to implement the Supreme Court of the United States’ decision in U.S. v. Arthrex, Inc., and specifically updated the Arthrex Q&As section. The PTO’s July 20, 2021, updates address the effect of Arthrex on Patent Trial & Appeal Board (PTAB) proceedings generally and ongoing proceedings in particular. In Arthrex, the Supreme Court held that appointment of PTAB administrative patent judges violated the Appointments Clause of the Constitution, and that the proper remedy was to vest the PTO director with discretion to overturn the PTAB’s decisions.

In section A of the Q&As, pertaining to the effect of Arthrex on PTAB proceedings, the PTO explained that the director has the option to sua sponte initiate director review of any final written decision at any point before the filing of a notice of appeal or before the time for filing such a notice has expired. The updated Q&As further explain that a request for director review is not an opportunity for a party to make new arguments or submit new evidence and imposes a 15-page limit on any request. The updated Q&As also clarify the mechanism to request review by the director. The update clarifies that a party cannot request both director review and a panel rehearing after the issuance of a final written decision, and if a party requests both it will be treated as a request for director review. However, if a panel rehearing is granted, a party can request director review of the rehearing panel decision.

In section B of the update, pertaining to the effect of Arthrex on ongoing PTAB proceedings, the PTO clarified the deadline for requesting a rehearing by the director and the circumstances under which the director will consider granting extensions of the rehearing deadlines.

In addition, the PTO added a new section, section D, pertaining to the interim internal process for director review. In section D, the Q&As address:

  1. What happens to a director review request when it is received by the PTO?
  2. What criteria does the advisory committee use when evaluating director review requests?
  3. How will the director identify decisions for sua sponte director review?

Regarding 1), the Q&As explain that requests for director review will be evaluated by an advisory committee established by the director. Regarding 2), the Q&As explain there is no exclusive list of criteria, but list criteria the advisory committee may consider. Regarding 3), the Q&As explain that the PTAB internal management review team will alert the director to decisions that may warrant director review.

Federal Circuit Lacks Appellate Jurisdiction over Standalone Walker Process Claims

The US Court of Appeals for the Federal Circuit ordered the transfer of a case asserting standalone Walker Process antitrust claims involving an unenforceable patent to the regional circuit, in this case the US Court of Appeals for the Fifth Circuit. Chandler v. Phoenix Services LLC, Case No. 20-1848 (Fed Cir. June 10, 2021) (Hughes, J.) The case originated in the US District Court for the Northern District of Texas, over which the Fifth Circuit has appellate jurisdiction. The decision to transfer was based on a subject matter jurisdiction analysis for Walker Process claims. The Federal Circuit reiterated that its precedent does not mandate exclusive Federal Circuit jurisdiction over all Walker Process cases.

In 2006, Phoenix Services and Mark Fisher (collectively, Phoenix) acquired a company called Heat On-The-Fly and its patent to protect a purported proprietary fracking process. Heat-On-The-Fly, and later Phoenix, sought to enforce the patent against numerous parties. During the patent application process, however, Heat On-The-Fly had failed to disclose numerous public uses of the fracking process prior to the application filing. In 2018, in an unrelated case, Energy Heating, LLC v. Heat On-The-Fly, the Federal Circuit, held that “failure to disclose prior uses of the fracking process rendered the . . . patent unenforceable due to inequitable conduct.” The plaintiffs in the case at hand, Ronald Chandler, Chandler MFG., Newco Enterprises and Supertherm Heating Services (collectively, Chandler), alleged that Phoenix’s continued enforcement of the patent violated Walker Process pursuant to § 2 of the Sherman Act.

Walker Process monopolization claims originate from a 1965 Supreme Court decision that recognized an antitrust cause of action under the Sherman and Clayton Acts when a party fraudulently obtains a patent for the purpose of attempted monopolization. Walker Process Equipment, Inc. v. Food Machinery & Chemical Corp. To succeed on a Walker Process claim, a plaintiff must satisfy two elements:

  • The plaintiff must show that the defendant obtained the patent through knowing and willful fraud on the US Patent & Trademark Office and enforced that patent with knowledge of its fraudulent procurement.
  • The plaintiff must be able to satisfy all other elements for a Sherman Act monopolization claim.

Pursuant to 28 U.S.C. § 1295(a)(1), the Federal Circuit retains jurisdiction over any civil case arising under any act of Congress relating to patents. In this instance, the Federal Circuit stated that Walker Process antitrust claims may relate to patents “in the colloquial use of the term,” but under 1988 Supreme Court precedent, Christianson v. Colt Indus., the Federal Circuit’s jurisdiction only extends to cases where the cause of action is created under federal patent law, or where the plaintiff’s right to relief “necessarily depends on resolution of a substantial question of federal patent law.”

Here, the Federal Circuit relied on its own 2018 precedent where it analyzed subject matter jurisdiction for Walker Process claims. Xitronix Corp v. KLA-Tencor Corp. (Xitronix I). Xitronix I involved alleged fraud by the defendants to obtain a patent. The Court acknowledged [...]

10th Circuit Falls into Line on Exceptionality Doctrine in Lanham Act Cases

Addressing whether the term “exceptional case” in the Patent Act differs in meaning from the same term used in the Lanham Act, the US Court of Appeals for the 10th Circuit upheld an award of attorneys’ fees granted under a motion filed under 15 U.S.C. 1117(a) and clarified that the exceptional case standard in the Lanham Act parallels the standard in the Patent Act. Derma Pen, LLC v. 4EverYoung Limited, et al., Case No. 19-4114 (10th Cir. June 8, 2021) (Lucero, J.)

In 2013, Derma Pen sued several companies for infringement of the “DERMAPEN” mark. Four years later, Derma Pen was granted a permanent injunction prohibiting the companies and “their officers, agents, servants, employees, attorneys, licensees, and anyone in active concert or participation with, aiding, assisting, or enabling Defendants” from using the mark. A few months later, Derma Pen filed for an order of contempt against one of the defendants, Stene Marshall, alleging that Marshall, with the help of other actors (related parties), had been violating the earlier-issued injunction. During the subsequent proceedings, despite being the plaintiff, Derma Pen routinely failed to meet its discovery obligations, causing the related parties to file as many as six discovery motions and resulting in the imposition of sanctions on Derma Pen.

Following an evidentiary hearing, the district court found Marshall in contempt of the injunction, but concluded that the related parties took no part in Marshall’s violation. Subsequently, the related parties moved for attorneys’ fees incurred in the contempt proceeding under the Lanham Act, 15 U.S.C. 1117(a). The district court granted the motion and awarded more than $190,000 in fees based on application of the “exceptional case” standard set forth in the Supreme Court of the United States’ 2014 decision in Octane Fitness v. Icon Health & Fitness. Specifically, the district court decided that the case was “exceptional” because:

  • Derma Pen produced “no evidence of damages.”
  • “[T]he evidence showed [Derma Pen] had no right to enforce the injunction.”
  • “[T]he evidence showed that [the] trademark was abandoned.”
  • “[M]onetary sanctions were imposed on” Derma Pen for misconduct and delay during discovery.
  • Derma Pen was “entitled to no relief against the [related parties].”

Derma Pen appealed.

The 10th Circuit affirmed the district court’s holding and fees award for the related parties, noting Derma Pen’s misconduct and delay during discovery. In so doing, the Court adopted the Octane Fitness standard as applicable to cases brought under the Lanham Act.

Practice Note: The 10th Circuit noted that it was acting consistently with other circuits that have considered application of the Octane standard to fee disputes under the Lanham Act, citing LHO Chicago River, L.L.C. v. Perillo (7th Cir. 2019) (collecting cases); Xereas v. Heiss (DC Cir. 2021); and Safeway Transit LLC v. Disc. Party Bus, Inc. (8th Cir. 2020).

Ninth Circuit Withdraws Opinion That Signaled Shift in Arbitration Landscape for Non-Signatories

The US Court of Appeals for the Ninth Circuit issued an order withdrawing its opinion in Setty v. Shrinivas Sugandhalaya, where the Court affirmed the denial of a non-signatory’s bid to arbitrate its claims for trademark infringement against one of the signatories to a contract under Indian law. Setty v. Shrinivas Sugandhalaya LLP, Case No. No. 18-35573 (9th Cir. June 8, 2021). The Court did not provide any reasoning for the withdrawal but indicated that a new disposition will be filed in due course.

What You Say Can and Will be Used Against You – Prosecution History and Prior Infringement Arguments

Noting patent owner’s prior litigation statements, the US Court of Appeals for the Federal Circuit upheld a district court ruling that a clear and unmistakable disclaimer in the prosecution history affected claim construction of an asserted patent. SpeedTrack, Inc. v. Amazon.com, Inc., Case No. 20-1573 (Fed. Cir. June 3, 2021) (Prost, J.)

In 2009, SpeedTrack filed suit against various online retailers alleging infringement of its patent directed to a method for accessing files in a filing system leveraging “category descriptions” to aid in organizing the files. The patent describes associating category descriptions with files using a “file information directory.” A “search filter” then searches the files using their associated category descriptions. A limitation that “the category descriptions hav[e] no predefined hierarchical relationship with such list or each other” was added during prosecution to overcome a prior art reference that leveraged hierarchical field-and-value relationships.

The district court initially adopted a proposed claim construction that lacked any reference to a field-and-value relationship, noting that the construction “account[ed] for the disclaimers made during prosecution.” Following a motion by SpeedTrack, the court concluded there was still a fundamental dispute about the scope of the claim term. After further analyzing SpeedTrack’s prosecution history, the court concluded that the history “demonstrate[d] clear and unambiguous disavowal of category descriptions based on hierarchical field-and-value systems” and issued a second claim construction order explicitly disclaiming “predefined hierarchical field-and-value relationships” from the scope of “category descriptions.” SpeedTrack subsequently stipulated to noninfringement under the second claim construction and appealed.

On appeal, the Federal Circuit stressed that prosecution-history disclaimer can arise from both claim amendments and arguments. Here, the prosecution history showed that the applicants “repeatedly highlighted predefined hierarchical field-and-value relationships” as a difference between the prior art and the patent claims in no uncertain terms. That SpeedTrack distinguished the prior art on other grounds did not moot its disclaimer statements.

The Federal Circuit also noted that SpeedTrack argued in litigation against another defendant that the purpose of the amendment was to distinguish the category descriptions from attributes that “have a ‘hierarchical’ relationship between fields and their values.” While the Court agreed with SpeedTrack that such litigation statements were not a disclaimer on their own (since they were not the inventors’ prosecution statements), these litigation statements further supported not accepting SpeedTrack’s arguments. The Court reminded SpeedTrack that it has cautioned (in Aylus and Southwall) that “the doctrine of prosecution disclaimer ensures that claims are not ‘construed one way in order to obtain their allowance and in a different way against accused infringers.’”

After assessing SpeedTrack’s prior statements, the Federal Circuit considered whether the disclaimer was clear and unmistakable. The Court concluded it was. In rejecting SpeedTrack’s argument that prior decisions not expressly finding disclaimer supported that prosecution statements were not clear and unambiguous, the Court noted the construction had not been fully considered in those judgments. Similarly, the Court rejected the notion that the district court’s issuance of a second claim construction order showed there was no clear and [...]

Submarine Sunk: Patent Prosecution Laches Pops GATT Bubble

Addressing for the first time whether the US Patent & Trademark Office (PTO) can assert prosecution laches as a defense in a civil action brought under 35 U.S.C. §145, the US Court of Appeals for the Federal Circuit held that the PTO could assert prosecution laches as a defense against four patent applications in a case where the plaintiff delayed presenting the claims for these applications over a period of at least 10 years. Hyatt v. Hirshfeld, Case Nos. 2018-2390; -2391; -2392; 2019-1038; -1039; -1049; -1070 (Fed. Cir. June 1, 2021) (Reyna, J.)

Gilbert Hyatt is well known for having built a prolific patent application portfolio based on nearly 400 initial filings made just before the United States changed from an issuance-based patent exclusivity system to a filing-based patent exclusivity system under the Uruguay Round of the General Agreement on Tariffs and Trade (GATT). By 2003, those 400 initial filings had exploded into 45,000 independent claims. Hyatt’s applications were so labor intensive that the PTO developed a separate examining unit specifically dedicated to their review. Many of these applications have been rejected.

After the PTO finally rejected four of Hyatt’s computer software patent applications, in 2005 Hyatt filed a § 145 action in the district court. Throughout the litigation, the PTO argued that Hyatt had routinely delayed prosecuting his patent applications and never complied with his verbal agreement with the PTO to streamline each application to apply for only one invention. Ultimately, after a five-day bench trial, the district court found that the PTO failed to prove it had taken sufficient action to advance prosecution of Hyatt’s applications. The PTO appealed.

Resolving the threshold issue on appeal of whether prosecution laches is even available to the PTO in a § 145 action, the Federal Circuit explained that the right to assert laches as an affirmative defense flows naturally from the PTO’s rights to reject applications based on laches and defend such rejections on appeal in the Federal Circuit on the same grounds. Any other conclusion, the Court recognized, would create incongruence and undermine the PTO’s authority. Such a defense is available even if raised for the first time in the district court, as “§145 actions open the door to new evidence.”

The Court found significant errors in the district court’s application of prosecution laches law. First, the Federal Circuit held that the district court too narrowly focused on the PTO’s specific conduct without considering the totality of the circumstances, including delays caused by Hyatt’s sweeping amendments and prosecution of other patent applications, as well as the relative costs and burdens of examining Hyatt’s gargantuan application portfolio. The Court was particularly critical regarding the district court’s assignment of blame to the PTO in its attempts to manage the unwieldy task before it.

After reviewing the evidence presented by the PTO, the Federal Circuit found that the PTO had amassed significant evidence of Hyatt’s delay of prosecution of his applications—i.e., “patterns of prosecution conduct [that] created a perfect storm that overwhelmed the [...]
