Late Expert Report Dooms Copyright Case

by | Apr 18, 2024 |

The US Court of Appeals for the Sixth Circuit weighed in for a third time on an eight-year copyright battle, this time finding that a district court did not abuse its discretion in excluding the plaintiff’s proposed expert or granting summary judgment to the defendant with respect to a copyright claim related to software. RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al., Case No. 23-1591 (6th Cir. Apr. 3, 2024) (Siler, Cole, Mathis, JJ.)

This case concerns a copyright infringement claim filed by Paul Rogers through his company RJ Control Consultants (RJC) against his former friend Jack Elder, sole owner of Multiject. Multiject engineers and sells industrial accessories related to plastic injection molding. Rogers developed technical diagrams and software source code for a rotary turntable control system for Multiject. After Elder obtained copies of the code and drawings, he fired Rogers and hired a different company, RSW, to implement the technology. Rogers obtained copyright registrations for the code and drawings and filed suit against Elder, Multiject and RSW for copyright and trademark infringement, as well as certain state law claims.

The district court granted summary judgment to the defendants on RJC’s copyright infringement and trademark infringement claims and declined to exercise supplemental jurisdiction over the state law claims. RJC appealed the dismissal of its copyright infringement claim. In December 2020, in RJ Control I, the Sixth Circuit affirmed the decision regarding the technical drawings but reversed and remanded the copyright claim to the district court, finding that the software technology was complex and required an expert to answer material questions related to the functionality of the code.

On remand, the district court established deadlines for expert disclosures and for filing dispositive motions and motions challenging experts. Both parties timely served expert disclosures in which they identified the names of their respective experts, but neither side produced an expert report with their disclosures.

In April 2021, the district court extended the discovery and motions deadlines but not the expert disclosure deadline. The defendants moved to exclude RJC’s expert on the grounds that RJC failed to properly disclose the expert because RJC did not produce an expert report. The defendants also filed motions for summary judgment. The district court granted the defendants’ motions, finding that RJC “failed to put forth any expert evidence that identifies any specific portions of the code that they claim are protectible.” RJC appealed.

The Sixth Circuit dismissed the second appeal for lack of appellate jurisdiction, finding that the district court’s decision was not final because the court had not disposed of Multiject and Elder’s counterclaim (RJ Control II). The case was remanded again. On remand, the district court dismissed the then-pending counterclaim. RJC appealed again.

RJC argued that the Sixth Circuit lacked jurisdiction to decide RJ Control I, just as it did in RJ Control II, because at that time the counterclaim remained pending in district court. The Court agreed and vacated its decision in RJ Control I, but then affirmed [...]

Mandamus Denied but Jurisdictional Door Left Open a Crack

by | Apr 4, 2024 |

The US Court of Appeals for the Federal Circuit denied a patent owner’s writ of mandamus seeking to prevent a defendant from amending its answer to add an affirmative licensing defense, but also noted that the defense was added only after the district court found that there were no remaining claims. In re VLSI Technology LLC, Case No. 24-116 (Fed. Cir. Mar. 18, 2024) (Moore, Taranto, Chen, JJ.)

VLSI asserted four patents against Intel in the Northern District of California. In December 2023, the district court granted summary judgment that two of the patents were not infringed and denied summary judgment of noninfringement on the remaining two patents. The parties additionally submitted cross motions for summary judgment on a licensing defense that turned on a forum selection clause, but the court denied both motions. To deprive the court of jurisdiction, VLSI granted Intel a covenant not to sue for infringement of the remaining two patents in the case. Two days later, Intel moved to amend its answer to add a counterclaim for a declaratory judgment that Intel was licensed to VLSI’s entire patent portfolio. The district court granted Intel’s motion, and VLSI filed a mandamus petition to block Intel’s amendment.

The Federal Circuit denied VLSI’s petition for two primary reasons. First, the Court determined that VLSI had not shown that it had no other available means of obtaining relief. The district court expressly invited the parties to brief issues pertaining to Intel’s licensing defense in subsequent briefing, and VLSI had since filed a motion to dismiss pertaining to this very issue. The Court also noted that VLSI could raise this issue on appeal after a final judgment. Second, the Court determined that VLSI failed to show that the district court abused its discretion in allowing Intel to amend its answer, finding that Intel acted diligently in seeking to amend its answer and that VLSI had long since known about the potential defense.

With respect to the substantive issue of whether the district court had subject matter jurisdiction, the Federal Circuit declined to offer an opinion at this stage. Nevertheless, in an apparent message to the court below, the final sentence of the Court’s opinion reads, “[w]e only note that Intel’s motion to amend its answer was filed after the court determined there were no remaining claims, such that no case or controversy remained before the court.”

Gentlemen, Start Your Engines: Even Bland Works Support Copyright

by | Mar 7, 2024 |

The US Court of Appeals for the Sixth Circuit affirmed an award of profit disgorgement and attorneys’ fees in a copyright infringement case, holding that even “workaday” or “humdrum” subject matter can support a valid copyright. Premier Dealer Servs. Inc. v. Allegiance Adm’rs LLC, Case No. 23-3394 (6th Cir. Feb. 26, 2024) (Sutton, C.J.; Clay, Bloomekatz, JJ.)

Premier and Allegiance both administered car dealers’ loyalty programs. Customers enrolled in these programs were required to meet certain conditions (such as changing the car’s oil at predetermined intervals), and if a part under warranty broke, the dealer would help the car owner initiate a claim through the loyalty program administrator. In conjunction with administering these programs, Premier created a loyalty certificate. The certificate collected the customer’s personal information and provided the program’s terms and conditions. Premier registered its certificate for copyright protection in 2008.

In 2018, Tricolor – one of Premier’s large, long-standing customers – switched its program to Allegiance. When Allegiance took over, it repurposed Premier’s loyalty certificate by simply updating the administrator’s contact information. Allegiance and Tricolor continued to use the otherwise unaltered certificate. Premier sued for copyright infringement.

The district court found that the certificate’s “dull” subject matter did not preclude copyright protection, enjoined Allegiance from further copyright infringement, and awarded Premier disgorgement of Allegiance’s profits as well as attorneys’ fees, totaling more than $1 million. Allegiance appealed, challenging the certificate’s copyrightability and the damages calculations.

As to the copyrightability of the certificate, the Sixth Circuit explained that while copyright requires originality, it is a low threshold that can be shown by making “non-obvious choices” or evidencing some creative spark. “[A]rtistic merit” is not necessarily required. The Court noted three categories that copyrights will not cover:

  • Facts that already exist in the world (although the expression of facts may be copyrightable)
  • Merger, “when there is only a single way to express a given set of facts” and
  • Scenes a faire, in which industry norms require expressing facts in a particular way.

Premier’s copyright was registered and therefore presumed valid, meaning the burden was on Allegiance to rebut that presumption. The Sixth Circuit rejected Allegiance’s challenge to the originality of Premier’s copyright, primarily because copyrights “protect all manner of works – mundane or lofty . . . so long as they satisfy the modest imperatives of originality.” Allegiance argued that Premier’s forms collected client information in a way that was unoriginal, because there was only one way to collect the information (merger) and because the layout was typical for the industry (scenes a faire). The Court looked to areas in which Premier indicated creativity, noting that its forms differed from other loyalty program certificates in evidence. Further, Premier made the creative choice to allow program members to select from various schedules for oil changes, instead of a single predetermined timetable. This and other evidence suggested choice, ideas and creativity, despite the functionality of the loyalty certificates.

The Sixth Circuit hinted at how Allegiance might have better established the [...]

Rock On: Clichéd Song Themes Don’t Infringe Copyright

by | Mar 7, 2024 |

The US Court of Appeals for the Fifth Circuit affirmed a district court’s summary judgment grant to an alleged song copier, finding neither evidence of factual copying nor striking similarity between the two songs. Kirk Johnston v. Chad Kroeger et al., Case No. 23-50254 (5th Cir. Feb. 19, 2024) (Jones, Haynes, Douglas, JJ.) (per curiam) (non-precedential).

Kirk Johnston is a musician and songwriter who plays guitar for the Texas rock band Snowblind (now called Snowblind Revival). In 2001, he wrote a song called “Rock Star.” Four years later, the Canadian rock band Nickelback released a song called “Rockstar” that became one of its most popular singles. In 2020, Johnston sued Nickelback, its record label and its music publishing company for copyright infringement. Nickelback moved for summary judgment, and the district court referred the motion to a magistrate judge. The judge recommended summary judgment in favor of Nickelback, finding no genuine dispute of material fact as to factual copying and finding that the two songs did not sound alike. The district court accepted the magistrate judge’s recommendation and dismissed Johnston’s infringement claim. Johnston appealed.

The Fifth Circuit reviewed the motion of summary judgment de novo. With respect to the element of factual copying, Nickelback’s members and executives claimed that they had never even heard of Johnston’s song. The Court found Johnston’s circumstantial evidence that Nickelback had access to his song unpersuasive. Johnston said that access could be inferred from the fact that the two bands were “moving in relatively the same circles” and that executives associated with Nickelback likely attended Snowblind’s shows. The Court said that Johnston’s arguments regarding the likelihood that Nickelback had access to his song “Rock Star” required “leaps of logic” not supported by the record and were “mere speculation.”

Johnston also unsuccessfully argued that the district court erred by not applying the “more discerning ordinary observer test” and by considering all versions of the songs on the record rather than just the “stripped down” versions. The Fifth Circuit pointed out that those standards only apply under a substantial similarity analysis, which requires a plaintiff to establish factual copying. Because there was no proof of access, much less copying, Johnston had to show a “striking similarity” between his song and Nickelback’s hit.

Johnston argued that his expert demonstrated that there were clear lyrical and musical similarities between the hooks of the songs, both of which concern the desire to be a rock star. However, the Fifth Circuit noted that the expert’s analysis was unpersuasive as to both the musical and lyrical similarities; concluding that neither was sufficiently similar to preclude all explanations but copying. The other themes in the song that Johnston pointed to as strikingly similar were “making lots of money,” “connections to famous people” and “references to sports.” The Court pointed out that as a general matter, those categories “are mere clichés of being a rockstar that are not unique to the rock genre.” As the Court put it, “[s]inging about being a rockstar is not [...]

Espresso Yourself: When Prosecution History as a Whole Doesn’t Demonstrate Clear, Unmistakable Disclaimer

by | Jan 4, 2024 |

The US Court of Appeals for the Federal Circuit reversed and remanded a district court’s claim construction and related summary judgment rulings after determining that the district court erred in construing a claim term by improperly limiting the plain and ordinary meaning of the term. K-fee System GmbH v. Nespresso USA, Inc., Case No. 22-2042 (Fed. Cir. Dec. 26, 2023) (Taranto, Clevenger, Stoll, JJ.)

K-fee filed a lawsuit against Nespresso alleging infringement of three K-fee patents directed toward coffee machine portion capsules that use a barcode. The district court issued a claim construction order construing the term “barcode,” which was present in every asserted claim. In the claim construction order, the district court characterized the dispute as “whether statements made by K-fee System GmbH . . . before the EPO [European Patent Office] concerning the meaning of ‘barcode’ should influence the plain and ordinary meaning of that limitation in these proceedings.”

In the EPO, Nespresso’s foreign affiliate had challenged the validity of K-fee’s related European patent, and K-fee had responded seeking to distinguish a particular piece of prior art (Jarisch/D1). Because the statements made to the EPO were submitted to the US Patent & Trademark Office during prosecution of the asserted patents, the district court analyzed the statements as part of the intrinsic record. The district court concluded that K-fee had “argued strenuously before the EPO for a particular ‘plain and ordinary meaning,’ which excluded ‘bit codes’—codes made up of two binary symbols.” Based on the EPO submissions, the district court construed the claim term “barcode” to:

its plain and ordinary meaning (i.e., a code having bars of variable width, which includes the lines and gaps), the scope of which is understood by the clear and unequivocal statements K-fee made to the EPO (i.e., the scope of barcode does not include the type of bit code disclosed in Jarisch/D1).

Based on that construction of “barcode,” Nespresso moved for summary judgment of noninfringement. It argued that its accused products operated identically to Jarisch capsules, which K-fee distinguished before the EPO, since both use a machine-readable code with only two binary symbols. The district court agreed. When applying its construction at summary judgment, the district court clarified that using “the type of bit code disclosed in Jarisch” … means “a binary code containing only ‘0s’ and ‘1s.’” Thus, the district court read K-fee’s EPO statements “to mean that a barcode must ‘contain more than only two binary symbols’ and, by extension, that any code that contains only two binary symbols could not be a barcode.” Because the court found that “there was no dispute that Nespresso’s accused products used a code having only two symbols,” it granted Nespresso’s motion for summary judgment of noninfringement. K-fee appealed.

Considering the issue de novo, the Federal Circuit reviewed K-fee’s statements to the EPO in context and disagreed “that the ordinary meaning of ‘barcode’ excludes ‘bit codes’ (in some sense, two-value codes) or even bit codes of ‘the type . . . disclosed in Jarisch’ to [...]

If the Label Is Skinny Enough – No Inducement Under Hatch-Waxman

by | Dec 14, 2023 |

The US Court of Appeals for the Federal Circuit made explicit what has long been considered implicit based on Warner-Lambert and its progeny, namely, that plaintiffs asserting an induced infringement theory to bar the entry of generic drugs in a Hatch-Waxman suit are subject to higher scrutiny than plaintiffs asserting the same theories outside of the Hatch-Waxman context. H. Lundbeck A/S v. Lupin Ltd., Case No. 22-1194 (Fed. Cir. Dec. 7, 2023) (Dyk, Prost, Hughes, JJ.)

Lundbeck owns the approved new drug application (NDA) for Trintellix®, a drug indicated for the treatment of major depressive disorder (MDD), as well as an expired compound patent for the associated active ingredient vortioxetine. Lundbeck also owns a patent that claims the use of vortioxetine as an antidepressant that can be prescribed in place of a traditional antidepressant to alleviate a patient’s negative sexual side effects, and another patent that claims the use of vortioxetine to treat cognitive impairment symptoms in patients with MDD.

Generic pharmaceutical companies filed abbreviated new drug applications (ANDAs) seeking approval to market generic versions of Trintellix® and asserting that Lundbeck’s unexpired patents listed in its NDA were invalid and would not be infringed by the generic companies. As required by the Hatch-Waxman Act (to prevent the entry of a generic on the market), Lundbeck sued the generic companies. At the district court, the defendants prevailed on the finding of noninfringement but lost on invalidity. Lundbeck appealed.

Lundbeck pressed its induced infringement and contributory infringement theories on appeal. Lundbeck argued that the generics infringed under the plain text of Hatch-Waxman (35 USC 271(e)(2)(A)) because they filed ANDAs seeking approval to market vortioxetine, and that “some uses of vortioxetine—for the treatment of patients that have previously taken other drugs but had to cease or reduce use due to sexually related adverse events and for the treatment of cognitive impairment—are covered by [Lundbeck’s listed] patents; and the labels do not prohibit prescribing vortioxetine for those uses, even though the defendants do not propose to market the drug for those patented uses.” In other words, Lundbeck argued that in terms of its inducement allegation, it made no difference whether a drug would be sold for a use not covered by Lundberg’s NDA-listed patents because the drug could be prescribed for those patented uses.

The Federal Circuit disagreed, explaining that “‘the use’ in § 271(e)(2)(A) refers to the use for which the FDA has granted an NDA” and for which the ANDA was submitted.” The Court emphasized that it is not “an act of infringement under . . . § 271(e)(2)(A) to submit an ANDA for a drug if just any use of that drug were claimed in a patent.” If it were, a brand could “maintain its exclusivity merely by regularly filing a new patent application claiming a narrow method of use not covered by its NDA,” which “would confer substantial additional rights on pioneer drug patent owners that Congress quite clearly did not intend to confer.” As the Court then held, “actions for [...]

Sound the Alarm: Reasonable Royalty Apportionment Analysis Overlooks “Sleep State”

by | Dec 14, 2023 |

After a jury found infringement of two patents and awarded almost $2.2 billion in damages, the US Court of Appeals for the Federal Circuit reversed the infringement finding for one asserted patent, vacated the damages award for the other asserted patent, and reversed the district court’s refusal to allow the alleged infringer to add a licensing defense. VLSI Technology LLC v. Intel Corporation, Case No. 22-1906 (Fed. Cir. Dec. 4, 2023) (Lourie, Dyk, Taranto, JJ.)

VLSI sued Intel for infringement of two patents. During the litigation, third party Finjan underwent a change in control after which it was controlled by the same parent entity as VLSI. Intel sought to amend its answer to add a licensing defense based on the broad definition of “affiliates” in its license agreement with Finjan, arguing that as a consequence of the change in control Intel was licensed to patents owned by VLSI. The district court denied the motion to amend.

At trial, the jury found literal infringement of one patent and infringement under the doctrine of equivalents (DoE) for the other patent. The jury awarded $2.2 billion in damages. Intel appealed.

The patent that the jury found infringed under the DoE was directed to devices, such as computer processors, having the ability to operate at a variety of frequencies. Depending on the operating conditions, a master device can provide a trigger input to a controller in response to a desired increase in device performance, and the controller can then adjust the clock frequency accordingly. Intel argued that the evidence of equivalents presented to the jury was legally insufficient to support a finding of infringement.

The Federal Circuit agreed and reversed the jury’s finding under the DoE. The Court stressed that for a patent owner to prevail under a DoE assertion, it must provide “particularized testimony and linking argument as to the insubstantiality of the differences between the claimed invention and the accused device.” While VLSI’s proof of equivalence was limitation specific, the testimony provided during the trial was insufficient to explain the “insubstantiality” of the differences between the claims and the Intel products. The Court specifically cited trial testimony by VLSI’s expert, who characterized the differences as “a difference of where an engineer draws the line . . . it’s a design choice.” In its explanation of why the analysis and testimony was insufficient, the Court explained that “[i]t is not enough [] to say that the different functionality-location placements were a ‘design choice.’ . . . VLSI had to prove—with particularized testimony and linking argument—that the elements of the Intel arrangement were substantially the same as the elements of the claimed arrangement. But VLSI offered no meaningful testimony doing so.”

Intel also appealed the damages award based on the patent that was found to be literally infringed. That patent was directed to certain features that provide separate scalable (as opposed to fixed) power supply voltages for both processors and memory devices, depending on the need of the device. VLSI’s expert presented a calculation of damages based [...]

A Step Forward for Choreography and Copyright

by | Nov 16, 2023 |

In a rare ruling on infringement of a copyright on choreography, the US Court of Appeals for the Ninth Circuit reversed the dismissal of a copyright infringement action, holding that the district court erred in its application of the substantial similarity standard in terms of the line between animation and choreography, and remanded for further proceedings. Hanagami v. Epic Games, Inc., Case No. 22-55890 (9th Cir. Nov. 1, 2023) (Murguia, C.J.; Paez, Nguyen, JJ.)

Kyle Hanagami, a Los Angeles-based choreographer with a substantial social media following, brought this action against Epic Games, creator of the blockbuster video game Fortnite. Hanagami alleged that Epic infringed his copyrighted choreography by incorporating a portion of his dance work into a virtual animation, known as an “emote,” that players can purchase for video game avatars to perform. Hanagami has created choreography for famous pop stars and globally recognized brands. The five-minute choreographic work at issue in this action was originally published on YouTube in November 2017 and had received almost 36 million views as of Hanagami’s original March 2022 complaint.

In August 2020, Epic released a version of Fortnite that included a new emote called “It’s Complicated.” The allegedly copied choreography consisted of a two-second combination of eight bodily movements set to four beats of movement, which Hanagami alleged “contain[ed] the most recognizable portion” of his choreography. Hanagami brought federal claims alleging direct and contributory infringement of a copyright, as well as a state law unfair competition claim.

The district court granted Epic’s motion to dismiss wherein Epic asserted that Hanagami had not plausibly alleged that the Fortnite emote displayed “substantial similarity” to his choreographic work. Hanagami appealed.

At issue in this appeal was whether the district court had properly applied the Ninth Circuit’s two-part test for substantial similarity in assessing Hanagami’s infringement allegations. The first part, called the “extrinsic test,” focuses only on the protectable elements of the plaintiff’s expression and assesses the objective similarities between the original and the allegedly infringing work. The second part, referred to as the “intrinsic test,” gauges similarity of expression from the perspective of the ordinary reasonable observer and is reserved for the trier of fact. Hence, at the pleadings stage, only the extrinsic test is applied.

The Ninth Circuit concluded that the district court erred in its application of the extrinsic test in two ways. First, the district court incorrectly analyzed Hanagami’s choreography as a series of unprotectable “poses,” rather than as a movement sequence that includes expressive elements such as body position, timing, use of space, energy, pauses and repetition. The Court explained that when a dance work is properly analyzed as a selection and arrangement of movements, Hanagami “plausibly alleged that the creative choices he made in selecting and arranging elements . . . are substantially similar to the choices Epic made in creating the emote.” Second, the district court erred in dismissing Hanagami’s claim because the choreography in the emote was “short” and a “small component” of the original work. The Ninth Circuit [...]

Still Exceptional: Fee-Shift Appropriate in View of Noninfringement Stipulation

by | Nov 16, 2023 |

In a split decision, the US Court of Appeals for the Federal Circuit affirmed a district court’s award of more than $5 million in attorneys’ fees, finding that the district court did not abuse its discretion in finding the underlying case “exceptional” under 35 U.S.C. § 285 or in calculating the total fees awarded. In re PersonalWeb Tech., Case No. 21-1858 (Fed. Cir. Nov. 3, 2023) (Reyna, Lourie, JJ.) (Dyk, J., dissenting).

Under 35 U.S.C. § 285, a “court in exceptional cases may award reasonable attorney fees to the prevailing party.” In Octane Fitness (2014), the Supreme Court of the United States held that an exceptional case is “simply one that stands out from others with respect to the substantive strength of a party’s litigating position (considering both the governing law and the facts of the case) or the unreasonable manner in which the case was litigated,” and the court considers the totality of the circumstances in making this determination.

PersonalWeb’s litigation positions at issue date back to 2011, when PersonalWeb first asserted five patents against an e-commerce company. After an unfavorable claim construction ruling, PersonalWeb stipulated to dismiss the action, and the district court entered the dismissal with prejudice.

In 2018, PersonalWeb asserted the patents against customers of the e-commerce company. The e-commerce company intervened and filed a new action against PersonalWeb seeking a declaratory judgment to bar the infringement actions against the customers based on the 2011 dismissal. Some of the cases proceeded while others were stayed. The district court granted summary judgment against PersonalWeb on claims directed to two allegedly infringing products for two separate reasons: because of the Kessler doctrine and claim preclusion, and because PersonalWeb conceded that it could not prevail after an unfavorable claim construction order.

The district court also entered an award of attorneys’ fees and costs against PersonalWeb, finding the case to be “exceptional” for the following reasons:

  • The infringement claims were “objectively baseless and not reasonable when brought because they were barred due to a final judgment in the [2011 action].”
  • PersonalWeb frequently changed its infringement positions to overcome the hurdle of the day.
  • PersonalWeb unnecessarily prolonged this litigation after claim construction foreclosed its infringement theories.
  • PersonalWeb’s conduct and positions regarding the customer cases were unreasonable.
  • PersonalWeb submitted declarations that it should have known were inaccurate.

The district court calculated the attorneys’ fees to be more than $5 million and costs to be more than $200,000. PersonalWeb appealed.

PersonalWeb argued that the district court erred in awarding fees and, even if fees were warranted, the court erred in assessing almost $2 million of the $5 million award. The Federal Circuit found that the district court did not abuse its discretion in any of its findings related to the fee grant, agreeing with the district court’s application of the Kessler doctrine. In Kessler, the Supreme Court ruled that after a final judgment of noninfringement, follow-up suits by the same patentee over the same non-infringing product against customers of the party [...]

No Money, Mo’ Problems: Speculative Damages Award Cannot Stand

by | Oct 26, 2023 |

The US Court of Appeals for the Federal Circuit upheld a district court’s claim construction and jury instructions but reversed a premature judgment as a matter of law (JMOL) on obviousness and an imprecise damages award. Cyntec Company, Ltd. v. Chilisin Electronics. Corp., Case No. 22-1873 (Fed. Cir. Oct. 16, 2023) (Moore, Stoll, Cunningham, JJ)

Cyntec sued Chilisin for willful infringement of two patents related to molded chokes, which are component parts in batteries and power supplies. Four events at trial led to this appeal. First, the district court construed the disputed “by means of” term by its plain meaning but also instructed the jury that when a result occurs “by means of” a factor, that factor “has an impact on”—but may not be the “only potential cause” of—the result. Second, Chilisin presented invalidity evidence, arguing that the asserted claims were obvious by one prior art reference in light of another.

Before Chilisin could cross-examine Cyntec’s rebuttal expert, the district court granted Cyntec’s JMOL, finding the patents not obvious. In the third event that led to the appeal, Cyntec presented a market-share lost profits theory of damages based on expert testimony. Chilisin unsuccessfully moved to exclude the testimony as being speculative and unreliable. The jury awarded more than $1.8 million in damages and the district court subsequently granted enhanced damages totaling more than $5.5 million. As for the fourth event, Chilisin unsuccessfully moved for JMOL and a new trial on multiple issues. Chilisin then appealed.

The Federal Circuit reviewed three issues on appeal:

  1. The nonobviousness JMOL
  2. The infringement findings
  3. The damages award.

Starting with nonobviousness, the Federal Circuit reversed the JMOL and remanded. While obviousness is ultimately a legal question, it relies on “numerous underlying factual findings,” including the scope/content/differences of prior art, the skill level of a person of ordinary skill in the art and objective indicia of nonobviousness such as commercial success. The Court found Chilisin had presented enough evidence to allow a jury to find the asserted claims obvious in light of the two prior art references presented. The Federal Circuit also analyzed the district court’s reasoning regarding the prior art and found that its “conclusions are either insufficient to support JMOL or unsupported by the evidence.” Thus, it was improper to withhold a partial fact issue from the jury.

Next, the Federal Circuit analyzed the infringement issue, dividing the analysis into the district court’s claim construction and jury instructions, and the jury’s infringement finding. Chilisin argued that the disputed term “by means of” should signal but-for causation, meaning the factor must cause the result. The Court agreed that this was one possible reading, but because the claim language did not read “by exclusive/primary means” or something similar, the disputed term could also encompass “mere contribution.” The Federal Circuit cited to the specification in support of its claim interpretation and ultimately upheld the district court’s claim construction and the consistent jury instructions. The Court rejected Chilisin’s argument that there was insufficient evidence of infringement, concluding [...]
