What a Croc! False Claim That Product Feature Is Patented Can Give Rise to Lanham Act Violation

by Karen Gover | Oct 17, 2024 | Trademarks

The US Court of Appeals for the Federal Circuit reversed and remanded a grant of summary judgment on a false advertising claim, concluding that a cause of action under Section 43(a) of the Lanham Act can arise when a party falsely claims to hold a patent on a product feature and advertises that feature in a misleading way. Crocs, Inc. v. Effervescent, Inc., Case No. 2022-2160 (Fed. Cir. Oct. 3, 2024) (Reyna, Cunningham, JJ.; Albright, District J., sitting by designation).

Crocs, the well-known maker of molded foam footwear, sued several competitor shoe distributors for patent infringement in 2006. The case was stayed pending an action before the International Trade Commission but resumed in 2012 when Croc added competitor U.S.A. Dawgs as a defendant to the district court litigation. The case was stayed twice more, from 2012 to 2016 and 2018 to 2020. In between those stays, in May 2016, Dawgs filed a counterclaim against Crocs and 18 of its current and former officers and directors, alleging false advertising violations of Section 43(a) of the Lanham Act. 15 U.S.C. § 1125(a). The individual defendants were later dismissed from the action.

Dawgs claimed that Crocs deceived consumers and damaged its competitors by falsely describing its molded footwear material, which it calls “Croslite,” as “patented,” “proprietary,” and “exclusive.” Dawgs alleged that it was damaged by Crocs’ false advertisements and commercial misrepresentations because Crocs suggested that its competitors’ footwear material was inferior. Croslite is in fact not patented, as Crocs conceded.

Crocs argued in its motion for summary judgment that Dawgs failed as a matter of law to state a cause of action under Section 43(a) because the alleged advertising statements were directed to a false designation of authorship of the shoe products and not to their nature, characteristics, or qualities, as Section 43(a)(1)(B) requires. The district court agreed. Applying the Supreme Court’s 2003 decision in Dastar Corp. v. Twentieth Century Fox Film Corp. and the Federal Circuit’s 2009 decision in Baden Sports, Inc. v. Molten USA, Inc., the district court granted summary judgment to Crocs. It reasoned that falsely claiming to have “patented” something is similar to a false claim of authorship or inventorship, not to the types of false advertising prohibited by the Lanham Act. Dawgs appealed.

Dawgs argued that the district court’s application of Dastar and Baden to the circumstances of its case was inapposite, and the Federal Circuit agreed. In Dastar, the petitioner copied a television series in the public domain, made minor changes, and sold it as a video set, passing it off as its own. The Supreme Court held that a false claim of authorship does not give rise to a cause of action under the Lanham Act. Similarly, in Baden, the Federal Circuit found that a basketball manufacturer’s false suggestion that it was the author of the “innovative” “dual-cushion technology” in its basketballs did not give rise to a false advertising claim under the Lanham Act.

In this case, however, the Federal Circuit reasoned that Croc’s false [...]

Don’t Tread on Illinois’ Absolute Litigation Privilege

by Connor M. Larson | Oct 17, 2024 | Trademarks

Addressing when Illinois law’s “absolute litigation privilege” bars certain counterclaims, the US Court of Appeals for the Federal Circuit affirmed a district court’s summary judgment finding that the plaintiff lacked a valid trade dress and reversed the district court’s decision that declined to apply the absolute litigation privilege as a complete defense to all of the alleged infringer’s counterclaims. Toyo Tire Corp v. Atturo Tire Corp., Case No. 22-1817 (Fed. Cir. Oct. 4, 2024) (Moore, Clevenger, Chen, JJ.) (nonprecedential).

Toyo and Atturo are competitors in the tire design business. After perceiving widespread copying of its tire designs, Toyo filed a district court action asserting design patent infringement and trade dress infringement against Atturo. Atturo asserted counterclaims, including false designation of origin under the Lanham Act and several state law counterclaims. The district court eventually dismissed with prejudice Toyo’s design patent infringement claims and proceeded with just the trade dress infringement claim.

A primary issue in the case was the description of the asserted trade dress. In its complaint, Toyo identified its trade dress merely as “the overall appearance” of its line of tires. Over the course of discovery, disputes arose concerning Toyo’s failure to distinctly describe its asserted trade dress. Toyo answered an interrogatory that requested this information with a non-limiting definition. The district court compelled Toyo to provide a more specific answer, which Toyo did by providing highlighted images.

Toyo’s fact witness was subsequently deposed under Fed. R. Civ. P. 30(b)(6) and gave answers that were inconsistent with Toyo’s interrogatory response. This led the district court to compel more testimony on what exactly the asserted trade dress contained, and which tire features met the definition of the trade dress, and which did not. On the advice of counsel, the corporate witness declined to answer more than 100 different questions. Toyo’s inability to describe its trade dress continued into expert discovery. When it served its expert reports, Toyo introduced yet another aspect of its trade dress – that the trade dress only included two-dimensional aspects. Toyo introduced this new argument to support the requirement that to qualify as trade dress the designated feature must be nonfunctional.

Atturo moved for sanctions. In granting the sanctions, the district court barred Toyo from asserting only the two-dimensional aspects of the trade dress, precluding Toyo from continually shifting its position because doing so “would effectively lead to trial by ambush.” Having struck the only argument that could save the trade dress from invalidity, the district court granted summary judgment of invalidity on both functionality and lack of secondary meaning.

Trial then proceeded only on Atturo’s counterclaims. The jury returned a verdict in favor of Atturo on six of the counterclaims, awarding $10 million in compensatory damages and $100 million in punitive damages. The district court set aside the jury verdict as it related to counterclaims of defamation and liability under the Illinois Deceptive Trade Practices Act. Both parties appealed.

The Federal Circuit affirmed the district court’s issuance of discovery sanctions, and the grant of [...]

No Matter How You Slice and Dice It, Conclusory Evidence Can’t Support Entire Market Value Damages

by Sydney E. McDermott | Oct 10, 2024 | Patents

The US Court of Appeals for the Federal Circuit concluded that the entire market value rule was not applicable where conclusory expert testimony was the only evidence that a product’s infringing features drove consumer demand, and therefore reversed. Provisur Techs., Inc. v. Weber, Inc., Case No. 23-1438 (Fed. Cir. Oct. 2, 2024) (Moore, C.J.; Taranto, Cecchi, JJ.)

Provisur sued Weber in the Western District of Missouri over three patents related to slicing and packaging meats and cheeses. The jury determined that Weber willfully infringed several claims of the three asserted patents and awarded damages. Following the trial, Weber moved for judgment as a matter of law (JMOL) on the issues of infringement and willfulness, and a new trial on infringement, willfulness, and damages. The district court denied Weber’s motion in its entirety. Weber appealed.

The Federal Circuit affirmed the district court’s judgment with respect to two of the asserted patents but reversed the infringement finding on the sole asserted claim of the third patent. Provisur’s infringement theory was that the consumer could program the device to infringe the limitations of the claim. However, at trial, Provisur provided no evidence that it was actually possible for the consumer to configure the device to practice the claim or that any consumer had ever done so. Some of the software necessary to be configured in an infringing manner was not accessible to the consumer. Instead, only Weber service technicians could access it. Provisur also proffered no evidence that the devices had ever actually been configured to infringe the claims, instead only offering evidence that the claims could have been infringed.

Next, the Federal Circuit assessed willfulness. Weber’s primary argument was that the district court improperly allowed expert testimony in violation of 35 U.S.C. § 298, which states that a party’s failure “to obtain the advice of counsel with respect to any allegedly infringed patent . . . may not be used to prove that the accused infringer willfully infringed the patent.” Provisur’s expert, who testified about industry standards for intellectual property management, “did not distinguish between legal and non-legal services when testifying about consulting a third party.” The Court concluded that that portion of the testimony was inadmissible and the remaining evidence could not support a finding of willfulness.

Finally, the Federal Circuit addressed the damages issue, specifically focusing on the reasonable royalty award. The infringing features were subparts of a larger accused product – which had many non-infringing features. The accused product contained multiple separate machines unrelated to the alleged invention.

Provisur’s royalty award was predicated on its use of the entire market value rule, where the base to which the royalty rate is applied is the cost of the entire accused product as opposed the cost of just the infringing part. The Federal Circuit noted that the entire market value rule is an acceptable theory, but it requires a showing that the infringing part “is the basis for customer demand.”

Provisur’s damages expert used the entire market value rule in calculating the [...]

Got Pillaged? Not If You Didn’t Follow the APA and FTCA

by Christian Tatum | Oct 10, 2024 | Patents

The US Court of Appeals for the Federal Circuit affirmed a district court decision dismissing claims under the Administrative Procedure Act (APA) and Federal Tort Claims Act (FTCA) against the US Patent & Trademark Office (PTO) relating to “pillaged patents.” The Federal Circuit found that dismissal was appropriate because the plaintiff failed to exhaust administrative remedies and the claims were barred under collateral estoppel. Winfrey v. Dep’t of Com., Case No. 24-1260 (Fed. Cir. Sept. 25, 2024) (Prost, Hughes, Cunningham, JJ.) (per curiam).

Eula Winfrey filed a pro se complaint in district court seeking “relief for the issue of two pillaged patents,” one of which was directed to a “step-up diaper” and the other to a “stroller buddy.” Winfrey claimed that the PTO “improperly denied her two patent applications and wrongfully deemed the applications to be abandoned,” and that she was the true inventor of Huggies Pull-Ups diapers. Interpreting Winfrey’s requests for relief as claims under the FTCA and the APA, the district court dismissed the claims related to the step-up diaper patent application for failure to exhaust administrative remedies. The district court found that Winfrey never presented an administrative claim to the PTO as required by the FTCA and that she did not file a petition to revive the application after the PTO deemed it abandoned. The district court also dismissed Winfrey’s APA claim related to the stroller buddy patent application based on collateral estoppel because Winfrey had previously litigated that claim. Winfrey appealed.

Applying Eleventh Circuit law, the Federal Circuit affirmed the district court’s dismissal of all of Winfrey’s claims. Addressing the FTCA claim first, the Court noted that “nowhere in any of her extensive filings before this court do we find evidence that Ms. Winfrey filed the requisite administrative claim to bring a claim for money damages against the USPTO.” The Federal Circuit also affirmed the district court’s dismissal of claims related to the stroller buddy application based on collateral estoppel, finding that Winfrey had brought the claim unsuccessfully three times. Finally, with respect to the APA claim for the step-up diaper patent application, the Court affirmed the district court’s dismissal for failure to exhaust administrative remedies after finding that Winfrey failed to “present any evidence that she filed a petition with the USPTO to revive her application or challenge its abandonment determination.”

Chickening Out: Reason for Trademark Abandonment Irrelevant Without Proof of Intent to Resume

by Karen Gover | Oct 3, 2024 | Trademarks

The US Court of Appeals for the First Circuit affirmed a district court’s summary judgment decision finding that the prior owner of a trademark for fresh chicken had abandoned the mark by failing to use it for three years and failing to show an intent to resume use of the mark. To-Ricos, Ltd. v. Productos Avícolas Del Sur, Inc., Case No. 22-1853 (1st Cir. Sept. 19, 2024) (Montecalvo, Lipez, Thompson, JJ.)

PAS, a Puerto Rico corporation, sold Pollo Picú branded chicken from 2005 to 2011. The Picú trademark consists of a cartoon chicken with the phrase “Pollo Picú” underneath it:

While Pollo Picú was once a well-recognized brand in Puerto Rico, PAS encountered administrative and financial challenges. In 2006 and 2009, it failed to file declarations with the US Patent & Trademark Office (PTO) attesting to the use of the mark as required by Section 8 of the Lanham Act. The PTO therefore canceled the Picú trademark registration. PAS stopped selling chicken bearing the mark after its bank froze PAS’s financing in 2011. The bank filed suit in January 2012 under a preexisting loan agreement in which PAS had granted the bank a lien over PAS’s assets, including the Picú mark. PAS offered to sell the company to To-Ricos, PAS’s main competitor, but no sale occurred.

In October 2014, PAS and the bank signed a settlement agreement requiring PAS to pay a stipulated sum by December 2014 or the bank would foreclose on most of PAS’s assets, but not the Picú mark. The agreement provided that the bank would retain its lien over the mark until the foreclosure proceedings concluded. PAS failed to make the payment, but the bank did not exercise its foreclosure rights. In June 2017, PAS moved for the Commonwealth Court to order the bank to foreclose on PAS’s assets or declare PAS free of its obligations to the bank. The Commonwealth Court granted the motion in November 2019.

In April 2016, To-Ricos applied to register the Picú mark with the PTO. Three months later, PAS applied to re-register the same mark and filed an opposition to To-Ricos’s application. A year later, PAS licensed the right to use the Picú mark in the United States to IMEX. IMEX sold chicken under the mark for a few months but stopped after To-Ricos sent cease and desist letters.

In June 2019, To-Ricos began selling Picú branded chicken. It also filed a lawsuit against PAS, seeking a declaratory judgment establishing To-Ricos as the legal owner of the Picú mark. To-Ricos moved for summary judgment, arguing that PAS had abandoned its mark. PAS opposed. The district court agreed with To-Ricos, noting that PAS admitted to not having used the mark in commerce for at least three consecutive years prior to To-Ricos’s application, and that PAS had not demonstrated its intent to resume use of the mark within that period. PAS appealed.

Rewind: Federal Circuit Grants En Banc Rehearing Over Royalty Damages

by Keval Amin | Oct 3, 2024 | Patents

The en banc US Court of Appeals for the Federal Circuit issued a per curiam order vacating its previous panel decision upholding a district court’s denial of the defendant’s motion for a new trial on damages. In that decision, the Federal Circuit found that the plaintiff’s damages expert adequately demonstrated the economic comparability of prior license agreements to a hypothetical negotiation between the parties. Now, the Court has granted the defendant’s petition for rehearing en banc. EcoFactor, Inc. v. Google LLC, Case No. 23-1101 (Fed. Cir. Sept. 25, 2024) (per curiam) (Moore, C.J.; Lourie, Dyk, Prost, Reyna, Taranto, Chen, Hughes, Stoll, Stark, JJ.) Judge Prost dissented in part in the original panel decision.

EcoFactor sued Google over Nest thermostats allegedly infringing EcoFactor’s HVAC patent. The initial appeal revolved around the validity of the patent, the infringement verdict, and the damages awarded. Google argued that the patent was directed to an abstract idea and therefore was patent ineligible under 35 U.S.C. §101. Google also argued that the district court erred in its rulings on noninfringement and damages. The Federal Circuit majority upheld the district court’s decisions, finding genuine issues of material fact on patent validity, substantial evidence of infringement, and admissible expert testimony supporting the damages award. The Court dismissed Google’s challenge to the expert’s use of license agreements for calculating royalties, as the Court found the methodology reasonable. However, Judge Prost’s dissent in the original panel decision criticized the damages calculation, arguing that the expert’s methodology lacked rigor, particularly for failing to apportion the patented technology’s value from other licensed patents.

The en banc Federal Circuit will now reconsider the practice of using a patent owner’s prior license agreements to determine royalty rates, a method that can become complicated when the scope of licenses varies or when lump sums and royalties are not clearly apportioned.

The en banc order directed the parties to file new briefs limited to the issue of whether “the district court[] adhere[d] to Federal Rule of Evidence 702 and Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), in its allowance of testimony from EcoFactor’s damages expert assigning a per-unit royalty rate to the three licenses in evidence in this case.”

Creative License: Fair Use Defense Paints Over Infringement Battle

by Kyle Sorenson, PhD | Oct 3, 2024 | Copyrights, Trademarks

Affirming the application of the fair use defense to copyright infringement, the US Court of Appeals for the Fifth Circuit determined that a district court’s sua sponte invocation of a fair use defense to parallel trademark claims was harmless error. The Court also affirmed that the district court did not abuse its discretion in awarding attorneys’ fees based on the prevailing party standard for copyright claims. Keck v. Mix Creative Learning Ctr., L.L.C., Case No. 23-20188 (5th Cir. Sept. 18, 2024) (Jones, Smith, Ho, JJ.)

Michel Keck, a multimedia artist, sued Mix Creative Learning Center, a Texas-based art studio, for copyright and trademark infringement after Mix Creative sold art kits featuring Keck’s dog-themed artwork and a brief biography, intended for at-home learning during the pandemic. Keck had registered her Dog Art series (in the form of decorative works) with the US Copyright Office and her name as a trademark with the US Patent & Trademark Office. Keck claimed that Mix Creative’s art kits violated her rights. After receiving notice of the lawsuit, Mix Creative promptly ceased selling its kits.

Following discovery, both parties filed cross-motions for summary judgment. The district court granted summary judgment in favor of Mix Creative on Keck’s copyright claim, finding fair use, and also granted summary judgment on the trademark claim sua sponte, as both parties had agreed that the fair use defense applied to both claims. The district court further awarded Mix Creative more than $100,000 in attorneys’ fees and costs, although it declined to hold Keck’s attorneys jointly and severally liable.

Keck appealed, challenging the copyright fair use finding and the district court’s sua sponte application of the fair use defense to the trademark claim. Mix Creative challenged the district court’s refusal to hold Keck’s attorneys jointly and severally liable for fees.

The Fifth Circuit affirmed the district court’s application of the fair use defense to Keck’s copyright claims. The Court focused on the first and fourth factors of the fair use defense (respectively, the purpose and character of the use and the effect of the use on the potential market for or value of the original work), noting that the courts typically give these two factors special attention.

On the first factor, the Fifth Circuit found Mix Creative’s use to be transformative. Although Mix Creative is a commercial enterprise, the art kits served an educational purpose, distinct from the decorative purpose of Keck’s original works. As a result, the likelihood of Mix Creative’s kits serving as a substitute for Keck’s original works in the market was low.

The fourth factor also favored Mix Creative, as the Fifth Circuit found no evidence that Mix Creative’s kits would harm the market value of Keck’s original decorative works. In fact, the Court suggested that the kits might enhance Keck’s reputation and sales by providing her with free advertising. Furthermore, Mix Creative operated in a different market (educational rather than decorative), and Keck had not demonstrated any history of selling derivative works for children’s art lessons. The [...]

Dolly Pardon: American Girl Can Sue Foreign Counterfeiter for Internet Sales

by Karen Gover | Sep 26, 2024 | Copyrights, Trademarks

The US Court of Appeals for the Second Circuit clarified its standards for establishing personal jurisdiction over foreign defendants that conduct business over the internet. American Girl, LLC v. Zembrka, DBA www.zembrka.com; www.daibh-idh.com, Case No. 21-1381 (2d Cir. Sept. 17, 2024) (Cabranes, Parker, Kahn, JJ.)

In 2021, American Girl, the famous doll manufacturer, filed suit against Zembrka in the US District Court for the Southern District of New York. American Girl brought multiple claims under the Lanham Act, including claims for trademark counterfeiting and trademark infringement, for advertising and sales of counterfeit American Girl dolls through Zembrka’s websites. Zembrka is located in and operates from the People’s Republic of China. American Girl was granted a temporary restraining order (TRO) that enjoined Zembrka from marketing, manufacturing, or distributing counterfeit American Girl products and from advertising counterfeit or confusingly similar American Girl marks.

Zembrka appealed and moved to dissolve the TRO and dismiss the complaint for lack of personal jurisdiction. Zembrka argued that it did not transact or do business in New York as required to establish personal jurisdiction under C.P.L.R. § 302(a)(1). American Girl asserted, with supporting evidence, that customers in New York could place orders through Zembrka’s interactive websites by inputting payment, billing, and shipping information, and that customers were sent confirmations of their orders to shipping addresses in New York. American Girl’s counsel purchased and paid for allegedly counterfeit American Girl merchandise through Zembrka’s website and received order confirmation emails. Zembrka conceded at oral argument that the allegedly counterfeit American Girl dolls were available via its website for purchase by people in New York.

The TRO was served on Zembrka. Two weeks later, Zembrka canceled the orders and refunded the payments for the purchases made by American Girl’s counsel. The district court granted the motion to dismiss for lack of personal jurisdiction, reasoning that because American Girl did not provide evidence that the allegedly counterfeit goods had shipped to New York, no business was transacted under § 302(a)(1). American Girl moved for reconsideration, providing evidence of other purchases of allegedly counterfeit merchandise by New York customers. It also produced evidence showing that New York customers purchased more than $41,000 worth of other Zembrka products over the past year via PayPal. The district court denied the motion because American Girl still did not demonstrate that any of the allegedly infringing products were actually delivered to New York, and customer payments were refunded. American Girl appealed.

The primary issue on appeal was whether American Girl sufficiently established that Zembrka transacted business in New York for the purposes of § 302(1)(a). The Second Circuit found that this requirement was easily satisfied, explaining that the district court had incorrectly interpreted the Second Circuit’s 2010 decision in Chloe v. Queen Bee of Beverly Hills as requiring a shipment to be an essential component of “transacting business.” It was enough that American Girl provided evidence that New York customers submitted orders and payments for allegedly counterfeit merchandise through Zembrka’s websites: “Section 302(a)(1) [...]

When Can Same Claim Limitation Have Different Meanings? When It’s Functional, Of Course

by Sydney E. McDermott | Sep 26, 2024 | Patents

Addressing for the first time whether a functional limitation must carry the same meaning in all claims, the US Court of Appeals for the Federal Circuit determined that it need not, vacating a district court decision to the contrary. Vascular Sol. LLC v. Medtronic, Inc., Case No. 2024-1398 (Fed. Cir. Sept. 16, 2024) (Moore, Prost, JJ.; Mazzant, Dist. J., by designation).

The seven patents asserted by Teleflex syin this case all come from a common application and are directed to a “coaxial guide catheter that is deliverable through standard guide catheters by utilizing a guidewire rail segment to permit delivery without blocking use of the guide catheter.” The asserted patents all share a common specification. However, the asserted claims differ in how they refer to the “side opening.” Some claims include the side opening as part of the “substantially rigid portion/segment” while other claims recite that the side opening is separate and distal to the “substantially rigid portion/segment.”

This case has a long procedural history involving an initial preliminary injunction motion and multiple inter partes reviews (IPRs). At the second preliminary injunction stage, Medtronic and the district court grouped the asserted limitations into two mutually exclusive groups:

Group One, which included the “substantially rigid portion/segment” claim limitation.
Group Two, which “required that the side opening not be in the substantially rigid portion” (emphasis supplied).

In denying Medtronic’s preliminary injunction motion, the district court questioned “how a skilled artisan could possibly be expected to understand the scope of a patent when the same device could simultaneously infringe two mutually exclusive claims within that patent.”

The district court then proceeded to claim construction. It rejected both parties’ initial constructions and appointed an independent expert – former US Patent & Trademark Office Director Andrei Iancu – to propose a construction. Teleflex argued that Iancu should adopt a split construction (i.e., one construction for the Group One limitations and another construction for the Group Two limitations). Medtronic argued that the claims were indefinite. Iancu rejected both proposed constructions but agreed with the district court on the mutual exclusivity of the two groups. The district court determined that all claims that included the “substantially rigid portion/segment” were indefinite, and since all the asserted claims included that term, the parties stipulated to final judgment. Teleflex appealed.

Teleflex argued that the district court erred in determining that the boundary of the substantially rigid portion must be the same for all claims. Medtronic argued that the claims were indefinite.

The Federal Circuit concluded that the district court erred when it determined that the Group One and Group Two limitations were mutually exclusive and indefinite. The Federal Circuit cautioned that affirming the district court’s conclusion would mean that claims in a patent cannot vary in how they claim the disclosed subject matter and that independent claims must be entirely consistent with other independent claims, neither of which is a restriction in how patentees may claim subject matter. The Federal Circuit explained that at the claim construction stage [...]

A New Vision: Collateral Estoppel Doesn’t Extend to Related Claims

by Alexander P. Ott | Sep 19, 2024 | Patents

The US Court of Appeals for the Federal Circuit reversed a district court order excluding expert validity testimony based on collateral estoppel stemming from an inter partes review (IPR) proceeding of a related patent, finding that an unpatentability decision in an IPR does not collaterally estop a patentee from making validity arguments about related claims in a district court litigation. ParkerVision, Inc. v. Qualcomm Inc., Case Nos. 22-1755; 24-2221 (Fed. Cir. Sept. 6, 2024) (Lourie, Mayer, Stark, JJ.)

This case has a long and complicated history. In 2011, ParkerVision sued Qualcomm for alleged infringement of eight patents related to wireless communications technology. In October 2013, a jury returned verdicts rejecting Qualcomm’s invalidity defense, finding 11 claims across four patents to be infringed by Qualcomm, and awarded $172 million in damages to ParkerVision.

In June 2014, the district court granted Qualcomm’s motion for a judgment as a matter of law on noninfringement, which the Federal Circuit affirmed in late 2015. Meanwhile, ParkerVision filed a second case against Qualcomm in May 2014 alleging infringement of 11 more patents. That case was stayed in favor of a Section 337 investigation that ParkerVision filed against Qualcomm at the International Trade Commission.

Qualcomm then filed 10 petitions for IPR, six of which targeted one of ParkerVision’s patents. While the challenged apparatus claims of that patent were found unpatentable during the IPR, the challenged method claims survived. The district court statutory stay (during the Commission proceeding) was lifted in December 2018. Prior to trial, the district court granted Qualcomm’s Daubert motions seeking to exclude ParkerVision’s expert’s testimony on invalidity due to collateral estoppel arising from the IPRs, and the expert’s testimony on infringement for being unreliable. The district court granted Qualcomm’s motion for summary judgment of noninfringement based on its finding that the asserted claims were materially similar to the claims from the first case. ParkerVision appealed.

In July 2024, after the briefing was completed and the Federal Circuit held oral argument, the Court dismissed the appeal for lack of appellate jurisdiction and returned it to the district court because Qualcomm’s invalidity counterclaims had not been adjudicated. The parties then filed a joint motion at the district court seeking entry of a final judgment, which was granted in August 2024. ParkerVision appealed again.

The Federal Circuit reinstated ParkerVision’s initial appeal and reversed the district court’s determination. On the summary judgment of noninfringement, the Court rejected the collateral estoppel finding because the district court failed to conduct claim construction to determine whether the scope of the claims was the same as in the first case. As for the district court’s exclusion of expert validity testimony due to the IPRs, the Federal Circuit concluded that because of the different legal standards for proving invalidity (preponderance versus clear and convincing), a finding underlying an unpatentability decision in an IPR does not collaterally estop a patentee from making validity arguments regarding related claims in district court litigation.

Finally, the Federal Circuit concluded that the district court had abused its discretion [...]
