Count On It, Plural Term Means More Than One

by | Mar 17, 2022 |

The US Court of Appeals for the Federal Circuit affirmed Patent Trial & Appeal Board (Board) patentability decisions after determining that the Board did not err in construing multiple terms within the challenged patents. Apple Inc. v. MPH Technologies Oy, Case Nos. 21-1532; -1533; -1534 (Fed. Cir. Mar. 9, 2022) (Moore, C.J.; Prost, Taranto, JJ.)

MPH owns three patents related to a method for forwarding a message from a first computer to a second computer via an intermediate computer via a network and provides secure message forwarding without relying on any extra encapsulation overhead. Apple petitioned for inter partes review (IPR) of MPH’s patents, challenging the claims in the three patents as obvious over a combination of non-patent literature (RFC3104) and a US patent (Grabelsky). During the proceedings, a series of claim construction disputes were raised. The Board issued final written decisions, finding that Apple failed to show that some claims would have been obvious over the combination of RFC3104 and Grabelsky. Apple appealed.

In seeking to overturn the Board’s decision, Apple raised four claim construction disputes. First, Apple argued that the Board erred in finding that the claim limitation “information fields” requires “two or more fields.” Apple argued that “a plural term covers one or more items” and thus the claim limitation was taught by Grabelsky, which uses a single field. Apple further argued that a word such as “plurality” must be used to clarify that the limitation requires more than one item. The Federal Circuit rejected Apple’s argument, explaining that common English usage presumes that a plural term refers to two or more items. The Court found that the Board did not err in construing the claim limitation because the term “information fields” is plural, thus requiring more than one field, and nothing in the claim language or written description suggested otherwise.

Second, Apple argued that the Board’s interpretation that the message was sent from the mobile computer directly to the first address was inconsistent with the claim limitation “intermediate computer configured to receive from a mobile computer a secure message sent to the first network address” in one of MPH’s patents. Apple argued that the passive language of the claim limitation suggested that “the mobile computer need not send the message to the first network address so long as the message is sent there eventually,” and thus the claim limitation was taught by RFC3104, in which a message sent to a first network address is received at another address before being forwarded to the first network address. The Federal Circuit rejected Apple’s arguments, finding that the Board did not err in construing the claim limitation because the plain language established direct sending of the message from the mobile computer to the first address, and nothing in the remainder of the claims or written description suggested otherwise.

Third, Apple argued that the Board erred in construing the term “substitute” in the claim limitation “substitute the unique identity read from the secure message with another unique identity prior to [...]

Long-Felt Need Not Felt Long Enough to Overcome Obviousness

by | Feb 24, 2022 |

The US Court of Appeals for the Federal Circuit upheld a finding that patents covering Narcan, a naloxone-based intranasal opioid overdose treatment, were obvious despite evidence of long-felt need. Adapt Pharma Operations Ltd. v. Teva Pharms. USA, Inc., Case No. 20-2106 (Fed. Cir. Feb. 10, 2022) (Prost, Stoll, JJ.) (Newman, J., dissenting).

In 2012, during the growing opioid crisis, the US Food & Drug Administration (FDA) identified a need for an improved intranasal naloxone treatment that could be FDA-approved and deliver the same amount of naloxone to the blood as an injectable formulation. In 2015, Adapt filed a patent application for Narcan, a method of nasally administering naloxone using about 4 mg of naloxone, benzalkonium chloride (BZK) and three other excipients. After Teva submitted an abbreviated new drug application (ANDA) to sell a generic version of Narcan, Adapt sued Teva for infringement. After a two-week bench trial, the district court determined that Adapt’s patents were obvious in view of prior art. Adapt appealed.

The Federal Circuit found no error in the district court’s conclusions that a skilled artisan would have been motivated to combine the prior art, that the prior art did not teach away from the claimed combination and that Adapt’s evidence regarding unexpected results, copying and industry skepticism was not probative of nonobviousness. The Court noted that a skilled artisan would have been motivated to improve on existing treatments because their shortcomings were well known, and the FDA had explicitly identified a need for an improved intranasal product. The claimed excipients also were separately taught in the prior art within the claimed concentration ranges. The Court agreed that a skilled artisan would have been motivated to combine these components to achieve the tonicity and pH required for a drug to be tolerable in the nose and to preserve and stabilize the formulation. While the prior art suggested that BZK causes naloxone degradation, the Court found that this did not teach away from its use because BZK was commonly used in intranasal formulations.

Turning to secondary considerations of nonobviousness, the Federal Circuit affirmed the following:

  • Narcan’s 56% increase in bioavailability was not “evidence of unexpected results” because BZK was a known permeation enhancer expected to increase bioavailability.
  • “[C]opying in the ANDA context is not probative of nonobviousness because . . . bioequivalence is required for FDA approval.”
  • The FDA’s recommendation to increase naloxone dosage in intranasal formulations negated any alleged industry skepticism regarding the higher dosage.

While the Federal Circuit found that the district court erred in finding there was no long-felt but unmet need for an effective intranasal naloxone product, the Court concluded that this error was harmless because the long-felt need began just three years before the patents’ priority date, which was not long enough to overcome the “strong case of obviousness . . . in view of the plethora of prior art.” The Court further agreed that competitors’ alleged failure to obtain FDA approval was not probative of nonobviousness and ultimately affirmed the district [...]

Specification Sheds Light on Broadest Reasonable Interpretation

by | Feb 17, 2022 |

The US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board (Board) obviousness decision, finding that the Board did not err in restricting the broadest reasonable interpretation of a claim term based on its use in the specification. Quanergy Systems, Inc. v. Velodyne Lidar USA, Inc., Case Nos. 20-2070; -2072 (Fed. Cir. Feb. 4, 2022) (Newman, Lourie, O’Malley, JJ.)

Velodyne owns a patent directed to a lidar-based 3D point cloud measuring system that can be used in self-driving vehicles to sense their surroundings. Quanergy petitioned for inter partes review of Velodyne’s patent, challenging the claims as obvious over a Japanese patent application (Mizuno). During the proceedings, the Board construed the broadest reasonable interpretation of the term “lidar (light detection and ranging)” to mean “pulsed time-of-flight (ToF) lidar” based on the written description of Velodyne’s patent and found that Mizuno’s system was not a ToF lidar system. The Board also presumed a nexus between the claimed pulsed ToF lidar system and Velodyne’s evidence of commercial success, relying on mapping the features of the claimed ToF lidar system to Velodyne’s commercial products. Based on its obviousness analysis and presumption of nexus, the Board issued final written decisions, finding that Velodyne’s patent was not unpatentable as obvious. Quanergy appealed.

Quanergy raised two arguments on appeal: The Board erred in its construction of the term “lidar,” and the Board erred in its obviousness analysis. Addressing claim construction, Quanergy argued that the Board did not use the broadest reasonable interpretation of “lidar” since “lidar” merely requires the use of laser light for detection and ranging, and thus “lidar” includes not only “pulsed ToF lidar” but also triangulation and other detection techniques described in Mizuno. The Federal Circuit rejected Quanergy’s argument, finding that the Board did not err in construing the term “lidar” according to its broadest reasonable interpretation because the written description focuses exclusively on “pulsed ToF lidar.”

Turning to obviousness, Quanergy argued that the Board erred in concluding that Velodyne’s claims were nonobvious over Mizuno because the expert testimony that the Board relied upon focused only on one particular embodiment of Mizuno’s device, which was not directed to a pulsed ToF lidar system. The Federal Circuit rejected this argument, finding that the Board did not err because Mizuno described “detect[ing] light reflected at an angle using position or image sensors, neither of which are used in pulsed time-of-flight lidar systems.” Based on this description, the Court found that Mizuno’s device was not a ToF lidar system.

Quanergy also argued that the Board failed to consider the issue of unclaimed features before presuming nexus. Quanergy argued that Velodyne’s evidence of commercial success related to those unclaimed features, such as a 360-degree horizontal field of view, a wide vertical field of view, a dense 3D point cloud and software, all of which were critical and materially impacted the functionality of Velodyne’s products. The Federal Circuit rejected this argument, finding that the Board did not err in finding a presumption of nexus [...]

Seeing Eye to Eye: Preliminary Injunction Affirmed for Patent Filed After Accused Product Was Sold

by | Feb 17, 2022 |

The US Court of Appeals for the Federal Circuit affirmed the grant of a preliminary injunction, finding that the district court did not abuse its discretion, clearly err in its underlying factual findings or abuse its discretion in setting the scope of the preliminary injunction. BlephEx, LLC v. Myco Indus., Inc., Case Nos. 2021-1149; -1365 (Fed. Cir. Feb. 3, 2022) (Moore, Schall, O’Malley, JJ.)

Myco sells AB Max, a mechanical device with an attached swab used for treating an eye condition known as blepharitis. Myco began marketing AB Max at a trade show in February 2019. One month later, BlephEx filed an application that later issued as a patent. The patent is directed toward cleaning debris from an eye during treatment of ocular disorders, including blepharitis. According to the patent, prior art treatment for blepharitis included at-home treatment where the patient would use a cotton swab, fingertip or scrubbing pad to scrub the eyelid margin in order to remove debris. Patients would often fail to adequately cleanse the eyelid margin, however. The patent’s solution is an electromechanical device with an attached swab for use by an eyecare professional to clean the patient’s eyelid margins.

The day the patent issued, BlephEx sued Myco and its chairman, John R. Choate, alleging that Myco’s AB Max infringed BlephEx’s newly issued patent. BlephEx moved the district court for a preliminary injunction prohibiting Myco from selling, distributing or offering the AB Max for sale. Myco opposed, arguing that a prior art reference (Nichamin) raised a substantial question of invalidity. The district court disagreed with Myco and granted the injunction. The district court noted that to anticipate, a prior art reference must disclose all elements of a claim arranged as in the claim, and Nichamin did not disclose combining the electromechanical applicator device depicted in one embodiment with a swab disclosed in another. The district court also rejected Myco’s argument that the patent examiner failed to consider Nichamin because he did not substantively discuss it during prosecution. The district court further rejected Myco’s obviousness argument as unsupported by expert evidence, finding Myco failed to overcome “the safety concerns of attaching a swab that is soaked in an abrasive to the Nichamin hand-held device.”

After the district court granted the preliminary injunction, Myco moved for reconsideration and argued that the preliminary injunction was overbroad because the AB Max had noninfringing uses. The district court rejected Myco’s argument, finding it was untimely and presented hypothetical noninfringing uses that were “outweighed by evidence that the only actual use of the AB Max was to treat anterior blepharitis,” which would likely infringe the asserted patent. Myco appealed.

The Federal Circuit affirmed the preliminary injunction grant. With respect to Myco’s anticipation argument, the Court found “Myco offers nothing other than attorney argument as to what the highly skilled artisan would do,” and this was insufficient to raise a substantial question of validity. The Court also noted that Myco had “put all of its eggs in the anticipation basket” and fatally failed [...]

Improper Claim Construction Requires Partial Remand of Obviousness Determination

by | Jan 6, 2022 |

The US Court of Appeals for the Federal Circuit issued decisions in two separate inter partes reviews (IPRs), one involving a patent related to radio frequency communication systems and the other involving a patent related to multi-processor systems. Intel Corporation v. Qualcomm Incorporated, Case No. 20-1664 (Fed. Cir. Dec. 28, 2021) (Prost, Taranto, Hughes, JJ.); Intel Corporation v. Qualcomm Incorporated, Case Nos. 20-1828, -1867 (Fed. Cir. Dec. 28, 2021) (Prost, Taranto, Hughes, JJ). Based on issues of claim construction and obviousness, the Court affirmed in part and vacated in part the Patent Trial and Appeal Board’s (Board) decision in the radio frequency communication systems patent IPR and vacated the Board’s decision in the multi-processor systems patent IPR.

Radio Frequency Communication System Patent IPR (1664)

In the IPR related to the radio frequency communication systems patent, Intel proposed that the claim term “radio frequency input signal” should take its ordinary meaning of an input signal having a radio frequency. Qualcomm argued that a person of skill in the art reading the patent would understand the phrase to reference the radio frequency signal that is received before down-conversion, and thus proposed that the term should mean “a signal centered at a carrier frequency at which the signal was transmitted/received.” The Board agreed with Qualcomm based on the intrinsic evidence.

Intel argued before the Board that certain claims of the radio frequency communication systems patent would have been obvious in light of the Der reference and the Valla reference. Qualcomm argued that a skilled artisan would not have been motivated to combine Der and Valla, because Der’s transistor would defeat the intended purpose of Valla’s amplifier. The Board agreed with Qualcomm. Qualcomm also submitted substitute claims. The Board accepted the substitute claims after finding that a skilled artisan would have lacked reason to combine Der and the Burgener reference to achieve the substitute claims. Intel appealed.

The Federal Circuit first addressed the threshold question of whether it had jurisdiction since no lawsuit had been filed against Intel. Despite the absence of any lawsuit against Intel itself, the Court found that Intel had standing because it had engaged in acts that previously resulted in assertion of the patent against one of Intel’s customers. Because Intel continues to sell the relevant products to that customer and others, it must address the risk of an infringement suit by Qualcomm. Qualcomm also refused to offer a covenant not to sue or stipulate that it would not reassert its prior infringement allegations involving the Intel products. The Court found that this refusal made Intel’s risk more than “mere conjecture or hypothesis.” Therefore, the Court found that Intel had standing to pursue the appeal.

Turning to the merits, the Federal Circuit affirmed the Board’s construction of “radio frequency input signal.” The Court explained that while both parties’ proposed constructions had appeal when considered in a vacuum, the proper inquiry required analysis of the surrounding claim language and specification. The Court found that linguistic clues in the claims suggested that [...]

Rounding Error: Intrinsic Evidence Informs Plain and Ordinary Meaning

by | Dec 16, 2021 |

Vacating a stipulated infringement judgment based on an incorrect claim construction, the US Court of Appeals for the Federal Circuit explained that it is improper to isolate claim language from the intrinsic evidence when determining the plain and ordinary meaning of a disputed term. AstraZeneca AB v. Mylan Pharms. Inc., Case No. 21-1729 (Fed. Cir. Dec. 8, 2021) (Stoll, J.) (Taranto, J., dissenting).

AstraZeneca sued Mylan Pharmaceuticals for infringement of three patents listed in the US Food and Drug Administration’s (FDA) orange book covering the Symbicort® pressurized metered-dose inhaler for the treatment of asthma and COPD. 3M submitted an abbreviated new drug application (ANDA) to the FDA to manufacture and sell a generic version of the Symbicort® inhaler and certain interests to the ANDA were later transferred to Mylan. After receiving a Paragraph IV letter from Mylan, AstraZeneca filed an infringement suit.

Shortly before trial, the district court held a claim construction hearing to determine the meaning of “0.001%,” the claimed concentration of PVP (one of the active ingredients). The district court construed the term based on its “plain and ordinary meaning, that is, expressed with one significant digit.” Based on this definition, Mylan stipulated to infringement and the district court entered judgment. The district court held a bench trial on invalidity, ultimately determining that Mylan did not prove that the claims were invalid as obvious. Mylan appealed the stipulated judgment stemming from the claim construction determination and the judgment of no invalidity.

First, Mylan challenged the district court’s claim construction of “0.001%.” AstraZeneca argued that the district court improperly construed the term to encompass a range from 0.0005% to 0.0014%. Mylan contended that, in view of the specification and the prosecution history, the term was to be defined precisely at 0.001% with only “minor variations” allowed. The Federal Circuit agreed, finding that Mylan’s proposed construction was more properly aligned with the patent’s description as further informed by the prosecution history.

The Federal Circuit stated that the proper construction of 0.001% only allowed minor variations from 0.00095% to 0.00104%. There was no dispute that the term 0.001% would ordinarily encompass the range of 0.0005% to 0.0014%. AstraZeneca argued that this “ordinary meaning” would control absent lexicography or disclaimer. The Court disagreed, finding that it would improperly isolate the term from the claim language, specification and patent prosecution history. The Court explained that the “ordinary meaning” is not the ordinary meaning in the abstract but is instead the “meaning to the ordinary artisan after reading the entire patent,” and therefore the claims must be read in view of both the written description and the prosecution history. The Court’s rationale for narrower construction was based on the intrinsic record reflecting that the written description and prosecution history showed that very minor differences in PVP concentration would impact stability.

The Federal Circuit found that the written description explained that stability was one of the most important factors and that even very minor differences in PVP concentration could impact stability. The written description also [...]

Shots Fired: Challenger Must Have Requisite Standing Before Appealing Unfavorable IPR Decisions

by | Dec 16, 2021 |

The US Court of Appeals for the Federal Circuit found, in the context of an appeal from an inter partes review (IPR) decision, that the appellant had Article III standing and affirmed a Patent Trial & Appeal Board (Board) decision, holding the challenged claims unpatentable as obvious. ModernaTX, Inc. v. Arbutus Biopharma Corporation, Case No. 20-2329 (Fed. Cir. Dec 2, 2021) (Lourie, J.)

Arbutus owns a patent pertaining to “stable nucleic acid-lipid particles (SNALP) comprising a nucleic acid (such as one or more interfering RNA), methods of making the SNALP, and methods of delivering and/or administering the SNALP.” Moderna petitioned for IPR of the patent, asserting three grounds:

  1. Moderna alleged that all claims of the challenged patent would have been anticipated and/or obvious in light of International Pat. Publ. WO 2005/007196 (‘196 PCT) or US Pat. Publ. 2006/0134189 (‘189 publication).
  2. Moderna alleged that all claims of the challenged patent would have been obvious over a combination of the ‘196 PCT, the ‘189 publication, Lin and Ahmad.
  3. Moderna alleged that all claims of the challenged patent were anticipated by US Pat. Publ. 2006/0240554 (‘554 publication), and alternatively that the claims would have been obvious over the ‘554 publication.

The Board rejected each of Moderna’s allegations, finding that the claims were not unpatentable as obvious. Moderna appealed.

Before addressing Moderna’s appeal on its merits, the Federal Circuit addressed whether Moderna had proper standing to challenge the Board’s decision. The Court stated that well-established precedent dictates that an appellant seeking review of a Board decision in an IPR must have suffered an injury in fact that is fairly traceable to the challenged conduct of the appellee and is likely to be redressed by a favorable judicial decision. The Court underscored that under IPR statute, there is no standing requirement for petitioners to request institution of IPR by the Board, meaning that a requester need not have a concrete stake in the outcome. Additionally, where the statue itself grants judicial review (such as in the case of an IPR), standing criteria of immediacy and redressability may be “relaxed.” Nonetheless, the Court explained that a party’s participation in the underlying IPR alone does not confer standing on that party to appeal the Board decision before an Article III court such as the Federal Circuit. The party seeking review (in this case Moderna) must show that it possesses requisite injury for standing to appeal.

Moderna asserted that substantial risk existed that Arbutus would bring an infringement suit against Moderna based on Moderna’s COVID-19 vaccine if the challenged patent was to remain valid. In support, Moderna submitted a declaration from its senior vice president and deputy general counsel that Moderna was working to harness proprietary mRNA technology and planned on releasing and applying for emergency use authorization for a COVID-19 vaccine in December 2020. The declaration also described how Arbutus’s conduct created a substantial risk that it would bring subsequent infringement action against Moderna. An example of such conduct was a series of public statements [...]

Obvious to Try Requires Reasonable Expectation of Success Tethered to Claimed Invention

by | Dec 16, 2021 |

Addressing obviousness in the context of method of treatment claims using particular drug dosages, the US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board (Board) final written decision holding that Teva failed to prove obviousness because it failed to show a reasonable expectation of success. Teva Pharms., LLC v. Corcept Therapeutics, Inc., Case No. 21-1360 (Fed. Cir. Dec. 7, 2021) (Moore, C.J.)

Corcept filed a New Drug Application (NDA) for Korlym, a 300 mg mifepristone tablet administered to certain patients with Cushing’s syndrome. The US Food and Drug Administration (FDA) approved Corcept’s application but required a drug-drug interaction clinical trial to determine drug safety when co-administered with strong CYP3A inhibitors such as ketoconazole (Lee memorandum). Corcept conducted the drug-drug interaction study and received a patent relating to methods of treating Cushing’s syndrome by co-administering mifepristone and a strong CYP3A inhibitor based on the data from the Lee memorandum.

Teva sought post-grant review of the patent after Corcept asserted it against Teva in district court. Teva argued that the patent would have been obvious in view of Korlym’s label and the Lee memorandum and submitted a supporting expert declaration. The Board held that Teva failed to prove that a skilled artisan would have had a reasonable expectation of success for safe co-administration of more than 300 mg of mifepristone with a strong CYP3A inhibitor, and thus failed to prove that the patent was obvious. Teva appealed, arguing that the Board erroneously required precise predictability rather than reasonable expectation of success in achieving the claimed invention, and that the Board did not apply Federal Circuit prior art range precedents.

The Federal Circuit affirmed the Board’s decision. Turning first to reasonable expectation of success, the Court explained that the analysis must be tied to the scope of the claimed invention. Because the patent required safe administration of a specific amount of mifepristone, the Board did not err in requiring Teva to show a reasonable expectation of success for a specific mifepristone dosage. Applying this correct standard, the Court found that the evidence supported that a skilled artisan would have had no expectation as to whether co-administering dosages of mifepristone above the 300 mg/day threshold set forth in the Korlym label would be successful. The Federal Circuit also agreed with the Board that Teva’s expert testimony supported a finding of no expectation of success in achieving the claimed invention based on inconsistent testimony before and after institution.

Turning next to the applicability of Federal Circuit prior art range precedents, the Federal Circuit found that Teva had failed to prove that the general working conditions disclosed in the prior art encompassed the claimed invention. Substantial evidence supported the Board’s finding that there was no overlap in ranges because the prior art (Korlym label and industry publications) capped the range of co-administration dosages at 300 mg/day. The Court also noted that Teva’s reliance on mifepristone monotherapy dosages to create an overlap in the claimed ranges failed because the patent claims [...]

Federal Circuit Makes Clear: Prior Failures in the Art May Demonstrate Non-Obviousness

by | Nov 11, 2021 |

Addressing the issue of obviousness of a patent directed toward a method of killing antibiotic-resistant bacteria using only visible light with no photosensitizer, the US Court of Appeals for the Federal Circuit reversed the Patent Trial & Appeal Board’s (PTAB) decision, finding no obviousness where the asserted prior art did not disclose a successful method that did not use a photosensitizer. University of Strathclyde v. Clear-Vu Lighting, LLC, Case No. 20-2243 (Fed. Cir. Nov. 4, 2021) (Stoll, J.) The Court held that the PTAB erroneously found a reasonable expectation of success where “[t]he only support for such a finding [was] pure conjecture coupled with hindsight reliance on the teachings in the [asserted] patent.”

Gram-positive bacteria, such as Methicillin-resistant Staphylococcus aureus (MRSA), are known to negatively affect health but effective methods of killing (or inactivating) such bacteria have been elusive. Photoinactivation is a way to kill antibiotic-resistant bacteria, and previous methods involved applying a photosensitizing agent to the infection and then activating the agent using light. Through experimentation, scientists at the University of Strathclyde discovered that application of visible (blue) light of wavelengths in the range of 400 – 420 nm was effective at inactivating bacteria such as MRSA without using a photosensitizing agent. The challenged patent claimed this method of using a photosensitizer for inactivating MRSA and other Gram-positive bacteria.

After Clear-Vu Lighting petitioned for inter partes review, the PTAB found the patent invalid as obvious in view of prior art disclosing methods of photoactivation using visible light. The university appealed.

The Federal Circuit reversed, finding that the prior art did not disclose all claim elements and there was no reasonable expectation of success in reaching the claimed invention by combining the prior art.

The Federal Circuit first addressed the PTAB finding that the prior art disclosed all claim limitations, finding that neither of the asserted prior art references taught or suggested “inactivation” of the bacteria without using a photosensitizer—as required by the claims. The Court noted that it “fail[ed] to see why a skilled artisan would opt to entirely omit a photosensitizer when combining [the] references,” finding it “particularly relevant” that one of the references actually “disclosed such a photosensitizer-free embodiment and was wholly unsuccessful in achieving inactivation.”

The PTAB also found that, based on a prior art teaching that “blue light may” inactivate “other bacterial cells that produce porphyrins,” a skilled artisan would have expected that MRSA could be inactivated by blue light without a photosensitizer due to the presence of porphyrins. In defense of the PTAB’s findings, Clear-Vu argued that support for the reasonable expectation of success could be found in the challenged patent itself. Citing its 2012 decision in Otsuka Pharm. v. Sandoz, the Federal Circuit harshly criticized this position, reiterating that the inventor’s own path to the invention is not the proper lens through which to find obviousness; “that is hindsight.”

The Federal Circuit explained that “not only is there a complete lack of evidence in the record that any bacteria were inactivated after exposure [...]

Objective Indicia of Nonobviousness for Design Patents: Same Nexus Requirement as Utility Patents

by | Aug 26, 2021 |

The US Court of Appeals for the Federal Circuit reversed two decisions by the Patent Trial & Appeal Board (Board), finding that a soup company and soup dispenser manufacturing company failed to prove the unpatentability of two design patents covering can dispensers. The Court also concluded that the analysis for objective indicia of nonobviousness for utility patents also applies to design patents. Campbell Soup Co. v. Gamon Plus, Inc., Case Nos. 20-2344, 21-1019 (Fed. Cir. Aug. 19, 2021) (Moore, J.)

Gamon Plus owns two design patents directed to “the ornamental design for a gravity feed dispenser display,” or a can dispenser. Gamon’s commercialized embodiment is called the iQ Maximizer gravity feed dispenser. For nearly a decade, Gamon sold tens of millions of dollars’ worth of its iQ Maximizer to Campbell Soup. Campbell attributed increased soup sales in part to the iQ Maximizer in its 10-K Securities and Exchange Commission reports (an industry publication) and in an internal marketing study. Campbell later began purchasing similar gravity feed dispensers from Trinity Manufacturing.

Gamon sued Campbell and Trinity for design patent infringement. Campbell and Trinity then petitioned for inter partes review (IPR) of Gamon’s patents. In its final written decisions, the Board found that Campbell and Trinity failed to prove unpatentability because the prior art was not similar enough to the claimed designs to constitute a proper primary reference. Trinity (Campbell) appealed.

In that appeal, the Federal Circuit disagreed, vacated and remanded. On remand, the Board again held that Campbell and Trinity failed to prove unpatentability, finding that the claimed designs would not have been obvious over the prior art. The Board reasoned that although the prior art alone had the same overall visual appearance as the claimed designs, there existed objective indicia of nonobviousness, including Gamon’s commercial success in selling iQ Maximizers to Campbell, Campbell’s praise of—and commercial success in—using the iQ Maximizer and Trinity’s copying of the iQ Maximizer. The Board presumed a nexus between those objective indicia evidences and the claimed designs because it found the iQ Maximizer to be coextensive with the claims, meaning that the product was essentially the disclosed invention with unclaimed features being insignificant. The Board also found that Gamon established such a nexus regardless of the presumption. Campbell and Trinity again appealed.

Again the Federal Circuit reversed, concluding that the claimed designs would have been obvious over the prior art. In doing so, the Court confirmed the Board’s finding that the prior art and the claimed designs shared the same overall visual appearance (which Gamon did not challenge) but found that the Board’s presumption of nexus and finding of a nexus-in-fact between the claimed designs and the evidence of commercial success and praise were not supported by substantial evidence. As for the presumption, the Court considered whether the iQ Maximizer was coextensive with the claimed invention. Nexus is presumed if the objective indicia evidence is tied to a specific product that is “coextensive” with the claimed invention. The Board recognized that the claimed portions of [...]
