Hit the Brakes: Experimental Use, Enhanced Damages Determinations Require Redo

by Paul Devinsky | May 12, 2022 | Patents

The US Court of Appeals for the Federal Circuit reversed and remanded a district court decision regarding experimental use under 35 U.S.C. § 102(b) and the application of enhanced damages based on an allegedly flawed noninfringement and invalidity opinion. Sunoco Partners Mktg. & Terminals L.P. v. U.S. Venture, Inc., Case Nos. 20-1640; -1641. (Fed. Cir. Apr. 29, 2022) (Prost, Reyna, Stoll, JJ.)

Sunoco sued Venture for infringement of four patents related to blending butane into gasoline. Venture argued that certain patent claims were invalid because they were subject to the on-sale bar of 35 U.S.C. § 102(b). The district court found that the sale at issue was primarily for experimentation and that the on-sale bar did not apply. Venture also argued that certain claim terms required measuring the actual vapor pressure of the butane and gasoline, but the district court rejected this argument. The district court found infringement and awarded Sunoco $2 million in damages, which it trebled to $6 million after finding that Venture lacked a good faith belief of invalidity or noninfringement because the legal opinion Venture relied upon was flawed. Venture appealed.

On appeal, Venture challenged numerous issues, including the district court’s rejection of its on-sale bar defense, construction of two claim terms and decision to enhance damages.

The Federal Circuit first addressed the district court’s finding that the on-sale bar did not apply to certain claims of two of the asserted patents. Reviewing de novo, the Court applied the Supreme Court’s 2019 Helsinn v. Teva decision, which requires that the on-sale bar applies if the invention was the subject of a commercial sale and ready for patenting. Analyzing the first prong, the Court looked to the contract language of the sale at issue. The inventor’s company offered to sell and install its butane blending technology at a customer’s fuel terminal more than one year before filing the patent application. The terms of the agreement required that the customer commit to purchasing at least 500,000 barrels of butane as consideration for the installation of the fuel mixing system. The Court noted that this agreement expressly described the transaction as a “sale” and did not reference any experimental purpose.

The Federal Circuit was not swayed by the lower court’s view that the contract did not require the customer to pay for the system directly, finding that a commitment to buy product in the future constituted a sale. The Court also gave little weight to the preinstallation testing terms of the agreement, finding that those tests were not experiments, but rather tests to confirm that the equipment was operating as contractually promised. Additional contract terms further cemented the Court’s view that this transaction was a sale, including language that the technology had already been “developed” and that title to the equipment transferred to the customer. The Court concluded that the sale of the system to the customer was not primarily for experimentation. The Court reversed the district court’s experimental-use determination and vacated its infringement determination, directing [...]

Golden State of Mind: Witness Convenience Isn’t Based Solely on Travel Distance

by Amol Parikh | May 5, 2022 | Patents

The US Court of Appeals for the Federal Circuit ordered a district court to transfer a patent infringement case from Texas to California because the district court had wrongly assessed facts relating to the convenience of witnesses when it originally denied a motion to transfer venue. In re: Apple Inc., Case No. 22-128 (Fed. Cir. Apr. 22, 2022) (Dyk, Reyna, Chen, JJ.) (non-precedential).

CPC Patent Technologies PTY Ltd. filed a lawsuit against Apple in the Western District of Texas, alleging that Apple’s mobile phones, tablets and computing products equipped with Touch ID, Face ID or Apple Card features infringed three of CPC’s patents relating to biometric security. Apple moved to transfer to the Northern District of California, arguing that its employees responsible for the design, development and engineering of the accused functionality resided either in California or outside of the United States, and that the employees most knowledgeable about the marketing, licensing and financial issues relating to the accused products resided in California. Apple explained that no employees with relevant information worked in Western Texas.

The district court denied Apple’s motion. After acknowledging that the action might have been brought in Northern California, the district court analyzed the private and public interest factors governing transfer determinations. The court determined that the factor concerning the convenience of willing witnesses slightly favored transfer. However, the court determined that the factor accounting for the availability of compulsory process weighed strongly against transfer. The district court also determined that court congestion and practical problems factors weighed against transfer based on its ability to quickly reach trial and the fact that CPC had another pending infringement suit in Western Texas. The district court recognized that Apple had identified seven relevant witnesses in California who would have to travel to Texas but found that inconvenience was counterbalanced by the presence of two Apple employees in Austin who CPC insisted had relevant information, and an Apple witness in Florida who would “find it about twice as inconvenient to travel to [Northern California] than to [Western Texas] because Texas sits halfway from Florida to California.” The district court also relied on its ability to compel the third-party Mac Pro manufacturer in Western Texas to attend trial. Finally, the Court noted that there was local interest in the dispute because Apple employs thousands of workers in Western Texas. Balancing these facts, the district court determined that Apple had failed to meet the burden of proving that Northern California was clearly more convenient that Western Texas, and thus denied the motion. Apple petitioned for mandamus review.

The Federal Circuit reversed, finding that Apple had shown clear entitlement to transfer to the Northern District of California. The Court found that the district court erroneously relied on two Apple employees in Austin whom CPC identified as potential witnesses and concluded that it was far from clear that either employee had relevant or material information. One employee had testified that he worked on authentication technology that was different from that accused by CPC, [...]

Missed Connection: Avoid Claim Construction Rendering Independent Claim Narrower Than Dependent Claim

by Tessa Kroll | Apr 14, 2022 | Patents

The US Court of Appeals for the Federal Circuit vacated a district court’s claim constructions concerning generic independent claims that were amended after a species restriction requirement, because the district court disregarded the doctrine of claim differentiation after incorrectly concluding that the examiner had mistakenly rejoined withdrawn claims. Littelfuse, Inc. v. Mersen USA EP Corp., Case No. 21-2013 (Fed. Cir. Apr. 4, 2022) (Prost, Bryson, Stoll, JJ.)

Littelfuse owns a patent directed to a fuse end cap for providing an electrical connection between a fuse and an electrical conductor. The specification teaches three embodiments of the invention:

A single-piece machined end cap comprising a mounting cuff and a terminal
A single-piece stamped end cap comprising a mounting cuff and a terminal
A two-piece assembled end cap comprising a mounting cuff, a terminal and a fastening stem attaching the mounting cuff to the terminal.

The originally filed claims included independent claims covering an end cap with a mounting cuff and a terminal, and dependent claims directed to the three embodiments. The claims directed to the two-piece assembled end cap embodiment contained the limitation that the terminal is press-fit onto the fastening stem.

During prosecution, the examiner issued a restriction requirement, asserting that the independent claims were generic to the three species in the dependent claims. Littelfuse elected to prosecute the assembled end cap species and the examiner withdrew the claims directed to the other embodiments. In response to a novelty rejection, Littelfuse amended the independent claims by adding the fastening stem element without specifying that the terminal is press-fit onto the stem. After allowing the amended independent claims, the examiner concluded that the previously withdrawn claims “require all the limitations of the . . . allowable claims,” and thus rejoined them.

Littelfuse sued Mersen for selling allegedly infringing fuses. The parties asked the district court to determine whether the fastening stem element in the independent claims limited Littelfuse’s patent to multi-piece end caps, despite the rejoined dependent claims being directed to one-piece embodiments. The district court found that the claim language, the specification and the prosecution history required the invention to have a multi-piece construction. First, the district court determined that the plain meaning of “fastening stem” was “a stem that attached or joins the other two components of the apparatus.” The district court then noted that the fastening stem was only mentioned in the specification in relation to the multi-piece embodiment in which the terminal is joined to the mounting cuff by the fastening stem. While Littelfuse argued that the US Patent & Trademark Office’s rejoining of the withdrawn claims meant that the independent claims covered unitary and multi-piece embodiments, the district court reasoned that the claims were rejoined based on a “misunderstanding” because they referred to the original independent claim, which did not include a fastening stem. In light of the district court’s finding that the independent claims covered only a multi-piece apparatus, the parties stipulated to non-infringement. Littelfuse appealed.

Applying the doctrine of claim differentiation, the [...]

First Sale Defense Bars Trademark Infringement Where Trademarked Component Is Adequately Disclosed

by Jodi Benassi | Apr 14, 2022 | Trademarks

A US Court of Appeals for the Ninth Circuit panel vacated a grant of summary judgment in favor of the plaintiff, holding that the first sale doctrine applies when a trademarked product is incorporated into a new product. Bluetooth SIG Inc. v. FCA US LLC, Case No. 21-35561 (9th Cir. Apr. 6, 2022) (per curiam).

Bluetooth SIG administers standards for Bluetooth technology. SIG owns and licenses the trademarks below to product manufacturers:

Fiat Chrysler Automobiles (FCA) makes cars that contain Bluetooth-equipped head units. The head units are made by third-party suppliers that have been qualified by SIG, but FCA has not taken steps to qualify the Bluetooth capabilities in its cars. FCA uses the SIG trademarks on its head units and publications.

SIG sued FCA under the Lanham Act for trademark infringement. In its defense, FCA asserted the first sale doctrine. Under the doctrine, the right of a producer to control the distribution of its trademarked product does not extend past the first sale of the product. For example, a purchaser who stocks, displays and resells a producer’s product under a producer’s trademark violates no trademark rights under the Lanham Act. The district court granted partial summary judgment for SIG on the first sale issue, finding that the first sale doctrine was inapplicable because FCA’s conduct went beyond “stocking, displaying, and reselling a product.” FCA appealed.

The Ninth Circuit found that the lower court erred when it took a narrow view of the Ninth Circuit’s 1995 decision in Sebastian Int’l, Inc. v. Longs Drugs Stores Corp., in which the Court stated that “it is the essence of the ‘first sale’ doctrine that a purchaser who does no more than stock, display, and resell a producer’s product under the producer’s trademark violates no right conferred upon the producer by the Lanham Act.” The panel noted that the Sebastian Court never purported to articulate the outer bounds of the first sale doctrine; instead it simply captured the unauthorized resale of genuine goods.

The Ninth Circuit explained that the first sale doctrine also applies when a trademark is used to refer to a component incorporated into a new end product as long as the seller adequately discloses how the trademarked product was incorporated. The Court cited to the 1925 Supreme Court precedent in Prestonettes, Inc. v. Coty, which effectively extends the first sale doctrine beyond the examples stated in Sebastian. In Prestonettes, the Supreme Court held that trademark law did not prohibit a manufacturer from using a trademark, not to indicate the goods, but to say that the trademarked product was a component in a product being offered as new and changed. The Ninth Circuit also noted its 1998 holding in Enesco Corp. v. Price/Costco, in which it found that the first sale doctrine protected a retailer that resold dolls in allegedly inadequate packaging to the extent the repackaging was disclosed. The Enesco Court explained that if the public was adequately informed that [...]

Re-Poster Child for § 230: Immunity under the CDA for Reposting Content of Another

by Sarah J. Fischer | Mar 31, 2022 | Copyrights

The US Court of Appeals for the First Circuit affirmed a district court’s decision to dismiss claims for defamation under the Communications Decency Act (CDA), 47 USC § 230, and for copyright infringement under the fair use doctrine. Monsarrat v. Newman, Case No. 21-1146 (Kayatta, Lipez, Gelpí, JJ.).

The parties’ dispute arose from a series of posts on a community message board. Residents of the Davis Square neighborhood in Massachusetts maintained a Live Journal forum for several years. In response to a revision of the Live Journal terms of service in 2017, Ron Newman, a member of the community, copied the entirety of the content from the Live Journal forum to another online platform: Dreamwidth. The copied content included a series of allegedly defamatory posts about Jonathan Monsarrat and a post that Monsarrat had copyrighted. Monsarrat sued Newman for both defamation and copyright infringement. Newman moved to dismiss the defamation claim under the CDA, § 230, and the copyright claim under the fair use doctrine. After the district court granted the motions, Monsarrat appealed.

The First Circuit first addressed the defamation claim under § 230. Newman argued that § 230 provided him immunity from defamation. Specifically, § 230 states “[n]o provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.” It also provides a shield from state law claims that would be “inconsistent with this section.” Courts apply a three-part analysis to determine whether a defendant is entitled to immunity under § 230:

Is the defendant a “provider or user of an interactive computer service”?
Is the claim based on “information provided by another information content provider”?
Does the claim treat the defendant “as the publisher or speaker” of that information?

Monsarrat did not challenge the fact that Newman was a “user” under the first prong. Regarding the second prong, the analysis hinged on whether Newman was an “information content provider,” which in turn relied on whether Newman was responsible for the allegedly defamatory content in whole or in part. The factual record showed that Newman did nothing but copy the allegedly defamatory posts that had been created by another. Monsarrat unsuccessfully argued that Newman was responsible because Newman copied the posts from Live Journal to a different digital platform with an allegedly different audience. The First Circuit was not persuaded, ruling that providing essentially the same content on a different platform did not make a defendant responsible for that content under § 230. Regarding the third prong, Monsarrat’s complaint clearly alleged that Newman was acting as a publisher. The Court affirmed the dismissal of the defamation claim under § 230.

Monsarrat’s copyright claim related to a Live Journal post by Monsarrat in the Davis Square forum. He had created a post with a link to Live Journal’s harassment policy, a quotation from the policy and a brief message regarding his attempts to report the abuse he felt he had suffered by other [...]

So You Wanna Play with Copyright? “Joyful Noise” Ostinato Isn’t Original Expression

by Jodi Benassi | Mar 24, 2022 | Copyrights

The US Court of Appeals for the Ninth Circuit affirmed a district court’s order vacating a jury award of damages for copyright infringement and granting judgment as a matter of law, explaining that the musical work alleged to have been copied did not qualify as an original work of authorship but consisted only of “commonplace musical elements.” Marcus Gray PKA Flame et al. v. Katheryn Elizabeth Hudson PKA Katy Perry et al., Case No. 20-55401 (9th Cir. Mar. 10, 2022) (Clifton, Smith, Watford, JJ.)

Key Definitions:

A musical scale is a sequence of musical notes or tones by pitch.
A subset of seven notes is called the minor scale and can be referred to with alphabetic names (A, B, C, etc.) or scale degrees (1, 2, 3, etc.).
An ostinato is a repeating musical figure (for example, 3-3-3-3-2-2).

In 2007, Marcus Gray (Flame) purchased an ostinato and used it in the song “Joyful Noise.” The song was released in 2008. While “Joyful Noise” did not achieve significant commercial success or airtime, it received millions of views online. In 2013, American singer-songwriter Katy Perry created “Dark Horse,” which was a hit, resulting in her performance at the Super Bowl halftime show in 2015.

The “Joyful Noise” ostinato consists of notes, represented as 3-3-3-3-2-2-2-1 and 3-3-3-3-2-2-2-6, whereas Dark Horse’s ostinato contains 3-3-3-3-2-2-1-5. Both have a uniform rhythm and equal note duration in time.

Plaintiffs sued Perry and her co-defendants for copyright infringement. Plaintiffs presented circumstantial evidence that the defendants had a reasonable opportunity to access “Joyful Noise” and that the ostinatos in both songs were substantially similar. Plaintiffs did not present direct evidence that Perry and the others had copied elements of the song, instead relying on testimony from their expert musicologist, Dr. Todd Decker.

Decker testified that the ostinatos were similar in many aspects, but he also testified that there was no single element that caused him to believe the ostinatos at issue were “substantially similar” when viewed “in isolation.” The jury also heard testimony from Perry’s expert, who disagreed altogether that the ostinatos were substantially similar.

The jury found that the defendants had a reasonable opportunity to hear “Joyful Noise” before composing “Dark Horse,” that the two songs contained substantially similar copyrightable expression and that “Dark Horse” used protected material from “Joyful Noise.” The jury found the defendants liable for copyright infringement and awarded $2.8 million in damages. The district court vacated the award and granted judgment as a matter of law to defendants, concluding that the evidence at trial was legally insufficient to show that the “Joyful Noise” ostinato was a copyrightable original expression. The plaintiffs appealed.

The Ninth Circuit explained that because the plaintiffs did not present any direct evidence that the defendants copied the “Joyful Noise” ostinato, they were required to show that the defendants had access to the work and that the ostinatos were substantially similar.

The Ninth Circuit began with its [...]

California, I’m Coming Home: Transfer to Venue Where Products Were Designed Is Appropriate

by Paul Devinsky | Mar 10, 2022 | Patents

The US Court of Appeals for the Federal Circuit denied a patent owner’s petition for writ of mandamus, finding that the district court properly transferred a case from the Eastern District of Virginia to the Northern District of California because the center of the alleged infringing activities occurred in California. In re: SunStone Information Defense, Inc., Case No. 2022-121 (Fed. Cir. Feb. 11, 2022) (Moore, Dyk, Stoll, JJ). (non-precedential).

SunStone filed a patent infringement suit against F5 Networks and one of its customers in the Eastern District of Virginia. F5 Networks moved to transfer the case to the Northern District of California pursuant to 28 U.S.C. § 1404(a), arguing that at the time of filing, SunStone was headquartered in Northern California, and the F5 Networks subsidiary that designed and developed the accused products was also located in the area. F5 Networks also noted that essentially all of the relevant documents and knowledgeable employees were in Northern California.

The district court granted F5 Networks’ motion, explaining that F5 Networks satisfied its burden of proving that transfer was warranted based on convenience of the parties and witnesses and because California was the “center of the alleged infringing activities.” The district court also noted that neither party disputed that the action “might have been brought” in the Northern District of California. SunStone petitioned for writ of mandamus.

The Federal Circuit applied the law of the regional circuit (the Fourth Circuit), which requires finding a clear abuse of discretion in order to overturn a district court’s transfer decision. The Court found that SunStone failed to meet this “stringent standard.” The Court also found that SunStone’s choice of forum was not entitled to significant weight because it was not SunStone’s home forum and had no specific connection to the infringement claims. The Court therefore denied SunStone’s petition.

Practice Note: This is another decision in a long line of recent Federal Circuit rulings relating to venue, which are summarized in an article related to a string of transfer denials in the Western District of Texas and our 2022 IP Outlook Report: The Developments Shaping Patent Law.

Alleged Trademark Infringer Remains Hog-Tied after Appeal

by Paul Devinsky | Feb 3, 2022 | Trademarks

The US Court of Appeals for the Tenth Circuit dismissed an appeal of a district court order denying a stay of a federal action for lack of jurisdiction under 28 U.S.C. § 1291 and reversed in part the district court’s grant of a preliminary injunction. The Trial Lawyers College v. Gerry Spence Trial Lawyers College at Thunderhead Ranch, Case No. 20-8038 (10th Cir. Jan. 27, 2022) (Bacharach, Briscoe, Murphy, JJ.).

The dispute between the parties arose out of a program called The Trial Lawyers College at Thunderhead Ranch in Wyoming. The College’s board of directors split into two factions known as the “Spence Group” and the “Sloan Group.” After the split, the two groups sued each other. The Spence Group sued in state court for dissolution of the College and a declaratory judgment regarding control of the board of directors. The Sloan Group sued in federal court claiming trademark infringement under the Lanham Act.

Both groups sought relief in the federal case. The Spence Group filed a motion to stay the federal court proceedings in light of the state court proceedings, and the Sloan Group requested a preliminary injunction. The district court denied the Spence Group’s stay and granted the Sloan Group’s request for a preliminary injunction. The Spence Group appealed both rulings.

The Tenth Circuit found that it lacked jurisdiction to review the district court’s stay denial. First, the state court resolved the dispute concerning board control, rendering part of the requested stay moot. Second, the Court determined that it lacked jurisdiction over the remaining motion for stay because it was not a final order. The Court explained that it needed to decide the appealability of the ruling based on the category of order rather than the particular facts of the case. The Court found that there was no unsettled issue of unique urgency or importance that warranted the Court exercising jurisdiction over the denial of the stay. Specifically, the Court explained that piecemeal litigation was unlikely because the state court already decided the issue of board control, and the Spence Group did not identify an unsettled issue of unique urgency.

The Tenth Circuit did exercise jurisdiction over the district court’s grant of a preliminary injunction. The Spence Group challenged the district court’s finding of irreparable harm, the order to remove sculptures bearing the College’s name, restrictions on what the Spence Group could say and the consideration of evidence presented after the hearing ended. The Court reviewed the district court’s findings under an abuse-of-discretion standard. The Court found that the district court did not abuse its discretion by finding irreparable harm, considering evidence after the hearing and enjoining the Spence Group from using words associated with the College. The Court explained that the district court reasonably found irreparable harm based on the College’s efforts to protect its name, logo and trademarks, as well as evidence of likely confusion among customers of the College based on the Spence Group’s use of those trademarks. As for the sculptures, the Court found [...]

Can’t Presume Personal Jurisdiction Exists When Challenged

by Lisa P. Rumin, Claire Danberg and Joshua W. Eastby | Feb 3, 2022 | Trademarks

The US Court of Appeals for the First Circuit affirmed a district court order dismissing a trademark infringement case for lack of personal jurisdiction, finding that if challenged, personal jurisdiction cannot be assumed into existence. Motus, LLC v. CarData Consultants, Inc., Case No. 21-1226 (1st Cir. Jan. 18, 2022) (Lynch, Selya, McConnell, JJ.)

Motus is a Delaware corporation headquartered in Boston, Massachusetts. CarData is a Canadian corporation with offices in Colorado, New York and Toronto. Both Motus and CarData offer tools for companies to manage employee expense reimbursement. Motus asserted a trademark over the phrase “corporate reimbursement services,” which was present in the meta title of CarData’s website. In November 2019, Motus asked CarData to remove the phrase from its website, and CarData did so within three days.

Motus nevertheless filed a federal lawsuit in the District of Massachusetts asserting Lanham Act claims for trademark infringement, trademark dilution and other state and federal causes of action. CarData moved to dismiss for lack of personal jurisdiction, among other grounds. The district court granted the motion to dismiss, finding that Motus failed to demonstrate either the existence of personal jurisdiction over CarData or that discovery into CarData’s jurisdictional claims were warranted. Motus appealed.

On appeal, the First Circuit reiterated that Motus bore the burden of demonstrating that the district court’s exercise of personal jurisdiction over CarData was proper, noting that although a plaintiff is not required to plead facts sufficient for personal jurisdiction, “it must—if challenged—ensure that the record contains such facts.” To demonstrate that personal jurisdiction over CarData was proper, Motus had to show that CarData had sufficient “minimum contacts” with the forum that were sufficiently related to the matter at issue and evidenced a “purposeful availment of the privilege of conducting business in the forum,” and also had to show the reasonableness of the exercise of personal jurisdiction in that forum. Motus argued that CarData had sufficient “minimum contacts” with Massachusetts for personal jurisdiction to lie there, primarily because CarData had offices elsewhere in the United States and because CarData maintained a website that was available to serve Massachusetts residents.

Given that Motus’s arguments for personal jurisdiction related primarily to the publicly available nature of CarData’s website to residents of Massachusetts, the First Circuit explained that “[i]n website cases we have recognized that the ‘purposeful availment’ element often proves dispositive.” Here, the Court found nothing in the record suggesting that CarData specifically targeted or did business with Massachusetts residents. The Court rejected Motus’s citation to informational content on the website because it was not specific enough to evidence intentional solicitation of business from any particular state. Nor was there evidence of substantial CarData revenue from Massachusetts. Thus, the Court found that there was no “purposeful availment.”

Finally, the First Circuit affirmed the district court’s denial of jurisdictional discovery into CarData’s “minimum contacts” with Massachusetts. The Court found that although Motus mentioned the availability of jurisdictional discovery in a single sentence in a footnote to its opposition to CarData’s motion to [...]

Nailed It: Expert Must at Least Meet Ordinary Skill Level to Testify from POSITA Perspective

by Alexander P. Ott | Jan 27, 2022 | Patents

Addressing a US International Trade Commission (ITC) decision finding a § 337 violation as to one patent but no violation as to four other patents, the US Court of Appeals for the Federal Circuit reiterated that a technical expert must at least meet the level of ordinary skill in the art of the asserted patents to testify from the perspective of a person of ordinary skill in the art (POSITA), whether for claim construction, validity or infringement. Kyocera Senco Indus. Tools Inc. v. ITC, Case Nos. 20-1046, -2050 (Fed. Cir. Jan. 21, 2022) (Moore, C.J.; Dyk, Cunningham, JJ.)

In 2017, Kyocera filed a complaint at the ITC seeking a § 337 investigation based on infringement allegations for six patents directed to battery-powered gas spring nail guns. The investigation was assigned to the Chief Administrative Law Judge (ALJ), who, in the context of a Markman order, adopted Koki Holdings America Ltd.’s uncontested level of skill in the art as including “experience in powered nailer design.” After claim construction, Kyocera dropped one patent from the investigation and went forward with infringement under the doctrine of equivalents as the sole basis for violation for four other patents.

Prior to the evidentiary hearing, Koki moved to exclude Kyocera’s expert’s testimony due to their admission during deposition that they did not have the experience in powered nailer design required by the adopted level of ordinary skill in the art. The Chief ALJ held that the Federal Circuit’s decision in AquaTex Indus. v. Techniche Sols. expressly required that Kyocera’s expert’s testimony be excluded as to infringement under the doctrine of equivalents but permitted the expert to testify as to literal infringement on one patent and on claim construction. After the evidentiary hearing, the Chief ALJ issued an initial determination that relied, in part, on Kyocera’s expert to find a particular element satisfied on the one remaining patent where literal infringement was asserted, but ultimately found no infringement due to other claim limitations. The Chief ALJ’s noninfringement decision as to the one remaining patent was then overturned on review by the full ITC, which found a § 337 violation and issued a limited exclusion order.

Kyocera appealed the Chief ALJ’s exclusion of its expert’s testimony on doctrine of equivalents, and Koki cross-appealed on the Chief ALJ’s decision to allow Kyocera’s expert to testify as to literal infringement and claim construction. The Federal Circuit reversed the ITC’s decision, holding that it was error to permit any infringement testimony from Kyocera’s expert and explaining that a witness must at least have ordinary skill in the art to offer testimony from the perspective of a skilled artisan for claim construction, validity or infringement, whether literal or under the doctrine of equivalents.

Alexander Ott was a member of Koki’s ITC trial team and the Federal Circuit appeal team in this case.
