Prosecution History Prevents Patent Owner from “Intercepting” Win on Appeal

by Thomas DaMario | May 20, 2021 | Patents

In reviewing whether the Patent Trial & Appeal Board (Board) correctly interpreted the meaning of “intercepting” in the context of Voice over Internet Protocol (VoIP) technology, the US Court of Appeals for the Federal Circuit found that the claim language and prosecution history supported the Board’s decision. The Court thus affirmed the Board’s construction and subsequent finding of obviousness. Uniloc 2017 LLC v. Apple Inc., Case Nos. 20-1403, -1404 (Fed. Cir. May 12, 2021) (Prost, C.J.)

Uniloc owns a patent directed to a system and method for using various VoIP features, such as caller-ID, call waiting, multi-line service, and different levels of service quality known as the “codec specification.” The patent explains that in order to generate revenue for these features, service providers must maintain control over which subscribers have paid for these additional features. To achieve that control, the system employs an enforcement mechanism that sits between the sender of the communication and the intended recipient. The enforcement mechanism ensures that both parties are authorized to use the particular features by intercepting the signaling message, determining whether the client is authorized, and filtering the signaling message based on the authorization. The majority of the claims require authorization related to only one service type. However, one of the claims (claim 18) requires authorization related to at least two service types.

Apple filed a petition for inter partes review (IPR), alleging that all claims of the patent were invalid as obvious over a prior art patent referred to as Kalmanek. Kalmanek discloses signaling messages that are routed through at least one “gate controller,” which can authenticate the identity of the calling party and authorize the services sought. The services include at least caller-ID and enhanced levels of call quality. Kalmanek’s process is accomplished by sending a SETUP message, which the calling party sends to the gate controllers and then to the intended recipient. After receipt, the called party sends a SETUPACK message along a return path to the gate controllers and then to the caller.

During the IPR, Apple asserted that the term “intercepting” a signaling message associated with the call, as recited in all independent claims, should be interpreted to mean “the signaling [message] is received by a network entity located between the endpoints of the call.” Uniloc disagreed and argued that the term should be interpreted as excluding the receipt of a signaling message by the intended recipient of the message. The Board agreed with Apple’s construction and subsequently found that all terms were invalid as obvious with the exception of claim 18. With respect to claim 18, the Board concluded that Apple failed to meet its burden to show that Kalmanek disclosed authorization related to a codec service. Furthermore, the Board opined that even assuming Apple had properly advanced such an argument, it would have lost on the merits.

On appeal, Uniloc challenged the Board’s construction of the “intercepting” term, and Apple cross-appealed the Board’s finding with respect to the non-obviousness of claim 18. The Federal Circuit affirmed [...]

Full Scope of Claimed Invention Must Be Enabled

by Paul Devinsky | May 20, 2021 | Patents

In a case relating to nucleic acid sequencing, the US Court of Appeals for the Federal Circuit upheld a jury verdict of non-enablement because a skilled artisan would have only known how to successfully practice a narrow range of the full scope of the nucleic acids covered by the asserted claim at the time of the invention. Pacific Biosciences of California, Inc. v. Oxford Nanopore Technologies, Case No. 21-2155, -2156 (Fed. Cir. May 11, 2021) (Taranto, J.)

PacBio sued Oxford for infringement of two patents related to methods for sequencing nucleic acids (such as DNA) using nanopore technology. The methods involve drawing nucleic acids through a nanometer-sized hole formed in a substrate. A voltage is applied to the substrate, and as the nucleic acids pass through the hole, the identity of each nucleic acid is identified based on changes in electric current passing through the substrate.

At trial, Oxford’s lawyer made opening remarks that included references to the potential applications of Oxford’s accused products to the then-emerging global COVID-19 crisis. PacBio immediately objected, and the district court gave exactly the curative instruction that PacBio requested. The district court also required that going forward, the parties give advance notice if they intended to make any reference to COVID-19. Ultimately, the jury found all asserted claims infringed, but also determined that the claims were invalid for lack of enablement under 35 USC § 112. In post-trial motions, the district court denied PacBio’s request that the court grant a new trial because of Oxford’s remark during opening statements regarding the accused products’ potential application to the then-emerging COVID-19 crisis. PacBio appealed.

On appeal, PacBio argued that the jury’s finding of lack of enablement was unsupported by the evidence, citing to testimony from its expert that a person skilled in the art at the priority date would have been able to successfully perform the methods of the asserted claims. The Federal Circuit disagreed, noting that the expert only demonstrated successful practice of the asserted claims for a narrow subset of nucleic acids covered by the claims—namely DNA hairpin molecules. The Court cited evidence where PacBio admitted through a stipulation that it had never performed the nanopore sequencing methods of the asserted claims, meaning its reduction to practice was purely constructive. The Court also noted that Oxford produced evidence that it was not until 2011 (two years after the priority date) that anyone in the field was able to use nanopore sequencing to sequence biological DNA—a different type of nucleic acid within the scope of the asserted claims. Thus, the Court found that PacBio had only demonstrated that a person of skill in the art would have been able to successfully practice a narrow range of the full scope of the nucleic acids covered by the asserted claim. The Court explained that it is not enough for enablement that the relevant artisans knew how to perform some nanopore sequencing before the priority date. Instead, what matters is the scope of the asserted claims, which relate [...]

Targeted Advertising Still Patent Ineligible Subject Matter

by Paul Devinsky | May 20, 2021 | Patents

The US Court of Appeals for the Federal Circuit found that targeted advertising is still an abstract idea and that a system providing targeted advertising must utilize something more than generic features and routine functions to be eligible for patent protection. Free Stream Media Corp. v. Alphonso Inc., Case No. 19-1506 (Fed. Cir. May 11, 2021) (Reyna, J.)

Free Stream Media, d.b.a. Samba, owns a patent directed to “a system providing a mobile phone user with targeted information (i.e., advertisements) that is deemed relevant to the user based on data gathered from the user’s television.” The system has three main components: (1) a networked device (e.g., a smart TV) that collects primary data, including program information, location, weather information or identification information; (2) a client device (e.g., a mobile device) on which applications run and advertisements may be shown; and (3) a relevancy-matching server that uses the primary data to select advertisement or other targeted data based on a relevancy factor associated with the user. Specifically, the relevancy-matching server “may also be configured to render the targeted data to the user through the networked device and/or the sandboxed application of the client device.”

Samba asserted infringement of the patent against Alphonso. In response, Alphonso filed a motion to dismiss on grounds that the asserted claims of the patent were directed to patent ineligible subject matter under 35 USC § 101. Alphonso subsequently filed a motion for summary judgment of non-infringement. The district court denied the § 101 motion but granted the summary judgment motion. Samba appealed the non-infringement finding, and Alphonso cross-appealed the § 101 finding.

The Federal Circuit started with the § 101 finding by first addressing Alice step 1 (abstract idea). The Court rejected the district court’s finding that the asserted claims were directed to “systems and methods for addressing barriers to certain types of information exchange between various technological devices . . . being used in the same place at the same time,” i.e., to bypass the security sandbox, and not an abstract idea of tailored advertising. To the contrary, the Court found that the asserted claims were directed precisely to the abstract idea of tailored advertising—specifically, gathering information about television users’ viewing habits, matching the information with other content and sending that content to a second device. Reiterating its prior holdings with respect to Alice step 1, the Court explained that the asserted claims only provided for the result of overcoming a security sandbox, and did not at all describe how that result is achieved. The Court also explained that even if the claims did recite a method for bypassing a security sandbox, Samba failed to demonstrate that this was anything more than a mere use of a computer as a tool, or that it somehow “improves the operability of these devices beyond providing a user with targeted content using generic processes and machinery.”

Turning to Alice step 2 (inventive concept), the Federal Circuit explained that the claimed abstract idea of providing targeted advertisements was not [...]

Federal Circuit Puts Patent Infringement Award/Injunction Back in the Box

by Jodi Benassi | May 13, 2021 | Patents

The US Court of Appeals for the Federal Circuit, exploring the use of Federal Rule of Civil Procedure 60(b)(3) under Ninth Circuit law, affirmed a district court’s ruling setting aside a monetary damages judgment and an injunction for fraudulent misrepresentations by a corporate patent owner’s president concerning prior art. Cap Export, LLC, et al. v. Zinus, Inc., et al., Case No. 20-2087 (Fed. Cir. May 5, 2021) (Dyk, J.)

In 2016, Cap Export sued Zinus seeking a declaratory judgment that claims of a patent owned by Zinus were invalid and not infringed. Zinus countersued, alleging that Cap Export infringed its patent covering a bed frame that can be packed into the headboard for compact shipping (known as a “bed in a box”). Zinus filed a motion for partial summary judgment of no invalidity of certain claims, and the court allowed Cap Export to depose Zinus’s then-president and “testifying technical expert,” Colin Lawrie. During the deposition, Lawrie denied knowledge of the existence of prior art. The district court concluded that the claims were not invalid and entered a judgment and permanent injunction against Cap Export.

Shortly thereafter, Zinus sued another company for patent infringement, and Cap Export discovered an exhibit on the docket describing a sale to Zinus of a bed that had all of the components of the bed (except the headboard) packed inside a zippered compartment in the headboard. Cap Export contacted the third party that sold the prior art beds to Zinus and obtained an invoice bearing the signature of Lawrie, the same witness who denied knowledge of such beds during his deposition. Cap Export moved to vacate the judgment and injunction on the grounds of fraud and misrepresentation under Rule 60(b)(3). After the district court granted the motion, Zinus appealed.

The Federal Circuit analyzed the issue under Ninth Circuit law, which requires evidence that the verdict was obtained through fraud, misrepresentation or other misconduct, and that the conduct prevented the losing party from fully and fairly presenting its defense. Ninth Circuit law further requires that the fraud was not discoverable by due diligence before or during the proceedings. Zinus argued that Cap Export’s counsel should have discovered the emails if they had exercised due diligence and propounded standard document requests for a patent case. Cap Export did not dispute that its written discovery served on Zinus did not specifically seek prior art and that it did not depose the inventor of the patent. Cap Export also did not dispute that although Lawrie’s deposition was taken, it was not taken under Federal Rule of Civil Procedure 30(b)(6).

The Federal Circuit explained that the issue was not whether Cap Export’s conduct fell below the standard of care for attorneys practicing patent litigation, but rather whether a reasonable company in Cap Export’s position should have had reason to suspect the fraud—i.e., that Lawrie had testified falsely—and, if so, whether it took reasonable steps to investigate. The Court found no showing that there was reason to suspect that Lawrie’s statements were [...]

Employment Agreement Assignment Provisions Don’t Reach Post-Employment Inventions

by Paul Devinsky | May 6, 2021 | Patents

The US Court of Appeals for the Federal Circuit rejected a biotechnology company’s argument that assignment provisions in its employment agreements granted ownership rights in post-employment inventions. Bio-Rad Laboratories, Inc. v. Int’l Trade Comm’n, Case No. 20-1785 (Fed. Cir. Apr. 29, 2021) (Taranto, J.)

10X filed an International Trade Commission (ITC) complaint against Bio-Rad, alleging that Bio-Rad’s microfluidic systems infringed 10X’s gene sequencing patents. Bio-Rad raised an affirmative defense alleging that it co-owned the asserted patents because two of the named inventors, formerly employed by Bio-Rad and its predecessor QuantaLife before forming 10X, conceived the ideas embodied in the patents while they were still employed by Bio-Rad. The two inventors had executed employment agreements, including provisions requiring disclosure and assignment of intellectual property created during their employment with Bio-Rad. The two inventors left Bio-Rad and formed 10X several months before the earliest conception date of the asserted patents.

The ITC administrative law judge rejected Bio-Rad’s co-ownership defense, concluding that Bio-Rad had not shown the inventive concept of the asserted patents was conceived before the inventors left Bio-Rad. The administrative law judge also found that Bio-Rad infringed 10X’s patents and that 10X satisfied the technical domestic industry requirement by practicing the asserted patents. The ITC affirmed the administrative law judge’s determinations and also found that the asserted claims were not invalid for indefiniteness. Bio-Rad appealed.

Bio-Rad argued, among other things, that the ITC erred in not finding co-ownership of the asserted patents based on the assignment provisions. Bio-Rad also contended that during their employment at Bio-Rad, the two inventors had conceived the ideas that contributed to the inventions reflected in the 10X patents, and the invention assignment provisions of their employment agreement required assignment of their interest to Bio-Rad.

The Federal Circuit affirmed the ITC. On the co-inventorship issue, the Court adopted the ITC’s conclusion and found that Bio-Rad had no ownership interest in the asserted patents, explaining that the assignment provisions did not apply to ideas developed during employment solely because the ideas ended up contributing to a post-employment patentable invention. The Court found that the language was limited to a grant of actual intellectual property, i.e., subject matter protectable as a patent created during the term of employment with Bio-Rad. The Court reasoned that a person’s work that contributes, even significantly, to a later patentable invention does not create protectable intellectual property until a patentable invention is made, and that therefore, the assignment provisions did not reach the ideas that Bio-Rad alleged were conceived during the inventors’ Bio-Rad employment.

The Court also noted policy reasons for limiting the reach of the assignment provisions, including the difficult compliance issues raised by requiring assignment of rights in post-employment inventions. The Court explained that such provisions might deter a former employee from pursuing work related to their prior work, or deter a potential future employer from hiring that individual to work in an area similar to that in which they had prior experience. The Court also agreed with the ITC’s conclusion that [...]

If You Can’t Build it, They Won’t Come: No Obviousness Based on Fanciful Engine Design

by Christopher M. Bruno | Apr 29, 2021 | Patents

Reaffirming that a person of ordinary skill in the art must have been able to actually create a disclosure at the time of invention in order for it to serve as an obviousness reference, the US Court of Appeals for the Federal Circuit reversed a decision by the Patent Trial & Appeal Board (the Board) in an inter partes review (IPR), concluding that a patent covering certain turbofan engine technology was not rendered obvious by a prior art publication that could not be realized into practice. Raytheon Techs. Corp. v. General Electric Co., Case No. 20-1755 (Fed. Cir. Apr. 16, 2021) (Chen, J.)

The issue on appeal was relatively straightforward. In an IPR, GE challenged as obvious a Raytheon patent that covered a specific design of geared gas turbine engine that provided for a “power density” higher than previously invented turbine engines. The patent defined “power density” as a “sea-level-takeoff thrust” divided by the engine turbine volume. During the IPR, GE relied on a 1987 NASA technical memorandum as art and argued that the reference, which envisioned superior performance characteristics based on an advanced engine that was made entirely of composite materials, rendered the challenged claims obvious. The parties did not dispute that this engine was unattainable in 1987, and may still be impossible today, because the envisioned composite materials do not yet (and may never) exist. The memorandum disclosed several performance factors, but not power density, sea-level-takeoff thrust or turbine volume. Nonetheless, GE argued, and the Board agreed, that the memorandum disclosed performance parameters that would have permitted an ordinarily skilled artisan to derive power densities that would have fallen within the range claimed in Raytheon’s patent.

On appeal, the Federal Circuit agreed with Raytheon, concluding that the imaginary engine of the NASA memorandum could not serve as an invalidating reference. In reversing the Board, the Federal Circuit reiterated two bedrock principles of obviousness law:

An obviousness reference must be enabled by the knowledge of an ordinarily skilled artisan at the time of the invention (but need not be self-enabling).
An invention cannot be rendered obvious by a non-self-enabling reference if no other prior art evidence or reference enables the non-self-enabling reference.

In addition, when a reference’s enablement is challenged, the party offering the reference bears a burden to establish that the reference, itself or in combination with other contemporaneous knowledge, was enabled.

Applying these principles here, the Federal Circuit determined that GE had not met its burden to show that the memorandum was indeed enabled. The Board, wrongly in the Court’s view, focused solely on whether an ordinarily skilled artisan was taught the parameters to ascertain a power density, rather than whether the prior art disclosed a turbofan engine possessing the requisite power density. Finding no evidence in the record to conclude that “a skilled artisan could have made the claimed turbofan engine with the recited power density,” the Court reversed.

Practice Note: Although this case does not break new obviousness ground, it reinforces the general [...]

Old Dawg, Still the Same Tricks: Bankruptcy Asset Successor is Also Inter Partes Re-Exam Successor

by Paul Devinsky | Apr 29, 2021 | Patents

The US Court of Appeals for the Federal Circuit issued a modified opinion correcting certain facts relating to a decision in which it originally concluded that because a plaintiff was a successor in bankruptcy, it was a successor in an inter partes re-examination. Mojave Desert Holdings, LLC v. Crocs, Inc., Case No. 20-1167 (Fed. Cir. Apr. 21, 2021 (modified), Feb. 11, 2021 (original)) (Dyk, J.)

In its original decision, the Court found that Mojave should be substituted for the original requestor following the sale of the original re-examination requestor’s right, title and interest in, to and under its assets to a holding company, which further assigned such assets and interests to Mojave. After the decision, Crocs moved for reconsideration because the original opinion incorrectly found that Mojave was the original requestor’s successor-in-interest. Instead, Crocs argued that Mojave had simply acquired assets from the original requestor, including litigation claims. Crocs argued that this distinction necessitated reconsideration of the original decision.

In response, the Federal Circuit issued a modified opinion that, while clarifying the facts, did not change the ultimate outcome. The Court found that the transfer of assets, including rights and claims of past acts of infringement, provided necessary Article III standing to maintain the proceeding. Accordingly, the Court allowed Mojave to be substituted for the original requestor.

Stated Purpose More Decisive than Definition in Construing Claims

by Paul Devinsky | Mar 25, 2020 | Patents

The US Court of Appeals for the Federal Circuit reversed a Patent Trial and Appeal Board (PTAB) obviousness decision, finding the decision was infected by an erroneous claim construction that failed to consider the purpose of the claimed invention. Kaken Pharmaceutical Co., LTD v. Iancu, Case No. 18-2232 (Fed. Cir. Mar. 13 2020)(Taranto, J.).

Kaken owns a patent claiming a method for topically treating fungal infections in nails. Fungal infections of the nail plate and nail bed are notoriously difficult to treat because topical treatments cannot penetrate the thick keratin in the nail plate. The patent describes an effective topical treatment with an antifungal, KP-103, having good permeability, retention capacity and activity in the nail plate. The patent specification notes that topical treatments known in the prior art were largely ineffective at penetrating the nail plate and treating onychomycosis.

Choosing Advocacy over Candor Renders Patent Unenforceable

by Paul Devinsky | Mar 19, 2020 | Patents

The US Court of Appeals for the Federal Circuit upheld the district court’s finding that the patents-in-suit were unenforceable due to inequitable conduct because of a failure to disclose information related to an offer for sale of the claimed invention made more than one year prior to the critical date. GS Cleantech Corp v Adkins Energy LLC, Case Nos. 16-2231, 17-1838; GS Cleantech Corp. et al. v. Big River Resources Galva, LLC et al., Case No. 17-1832 (Fed Cir. March 2, 2020) (Wallach, J.)

Patent-Eligible Improvements to Computer Functionality Must Be Directed to an Improvement of the Computer or Network Platform

by McDermott Will & Emery | Mar 19, 2020 | America Invents Act, Patents

Applying the US Supreme Court’s Alice v. CLS framework, the US Court of Appeals for the Federal Circuit upheld a Patent Trial and Appeal Board (PTAB) finding patent claims directed to data management and processing systems for merely storing advertising data were not patent eligible under 35 U.S.C. §101. Customedia Techs., LLC v. Dish Network Corp., Case No.18-2239 (Fed. Cir. Mar. 6, 2020) (Moore, J.)
