Family Matters, but Only Sometimes if Claim Construction Is Involved

by | Nov 10, 2022 |

The US Court of Appeals for the Federal Circuit reversed a district court’s claim construction, explaining that the use of a restrictive term in a definition in an earlier application does not reinstate that term in a later patent that purposely deletes the term, even if the earlier patent is incorporated by reference. Finjan LLC v. ESET, LLC, Case No. 21-2093 (Fed. Cir. Nov. 1, 2022) (Prost, Reyna, Taranto, JJ.)

Finjan filed a lawsuit against ESET for infringement of five patents directed to systems and methods for detecting computer viruses in a “downloadable” through a security profile. Each of the asserted patents was part of the same family, and each claimed priority to the same provisional application. The term “downloadable” appeared in the claims of all the asserted patents but was defined slightly differently in the various patents in the family. The original provisional application defined “downloadable” as “an executable application program which is automatically downloaded from a source computer and run on the destination computer.” Two of the non-asserted patents in the family defined “downloadable” as “applets” and as “a small executable or interpretable application program which is downloaded from a source computer and run on a destination computer.” Two of the asserted patents defined “downloadable” as “an executable application program, which is downloaded from a source computer and run on the destination computer.” The two asserted patents incorporated by reference one of the non-asserted patents. The other three asserted patents did not include a definition of “downloadable,” but they incorporated by reference one of the asserted patents and one of the non-asserted patents that defined “downloadable.”

The district court construed the term “downloadable” as used in the asserted patents to mean “a small executable or interpretable application program which is downloaded from a source computer and run on a destination computer.” The district court based its construction on the incorporation by reference of one of the non-asserted patents, reasoning that although the patent family contained “somewhat differing definitions,” these definitions “can be reconciled.” In particular, the district court found that based on the definitions and examples included throughout the various patents in the family tree, the term “downloadable” in the asserted patents should be construed to include the word “small” as defined in the non-asserted patent. ESET moved for summary judgment of invalidity due to indefiniteness based on the word “small” as used in the adopted construction of “downloadable.” The district court granted the motion. Finjan appealed.

The Federal Circuit began by reciting the well-known maxim that claims must be read in light of the specification, which includes any patents incorporated by reference since those patents are “effectively part of the host patents as if they were explicitly contained therein.” However, the Court explained that “incorporation by reference does not convert the invention of the incorporated patent into the invention of the host patent.” Instead, the disclosure of the host patent provides context to determine what impact, if any, the patent incorporated by reference will have on the [...]

Supreme Court to Consider Whether Lanham Act Reaches Foreign Defendants’ Extraterritorial Conduct

by | Nov 10, 2022 | ,

The Supreme Court of the United States agreed to review the geographic scope of the Lanham Act and the extent to which trademark owners can use US trademarks to police foreign sales. Abitron Austria GmbH et al. v. Hetronic International Inc., Case No. 21-1043 (Supr. Ct. Nov. 4, 2022) (certiorari granted). The question presented is as follows:

Whether the court of appeals erred in applying the Lanham Act extraterritorially to petitioners’ foreign sales, including purely foreign sales that never reached the United States or confused U.S. consumers.

In the underlying case, the US Court of Appeals for the Tenth Circuit upheld a damages award for Hetronic International based on its conclusion that the Lanham Act can affect conduct that substantially affects US commerce, such as the products Hetronic Germany and others sold to European customers.

The US Solicitor General suggested that the case is “a suitable vehicle” to clarify the Lanham Act’s geographic scope, noting that the Lanham Act provides a remedy for a foreign defendant’s use of a US trademark abroad only if that use is likely to cause confusion within the United States.

Supreme Court to Consider Enablement Requirement

by | Nov 10, 2022 | ,

The Supreme Court of the United States agreed to consider how much a patent must disclose in order to meet the enablement requirement under 35 U.S.C. § 112. Amgen Inc., et al. v. Sanofi, et al., Case No. 21-757 (Supr. Ct. Nov. 4, 2022) (certiorari granted). The question presented is as follows:

Whether enablement is governed by the statutory requirement that the specification teach those skilled in the art to “make and use” the claimed invention, 35 U.S.C. § 112, or whether it must instead enable those skilled in the art “to reach the full scope of claimed embodiments” without undue experimentation—i.e., to cumulatively identify and make all or nearly all embodiments of the invention without substantial time and effort.

Amgen owns two patents that describe antibodies that bind to PCSK9 protein and lower LDL cholesterol levels by blocking PCSK9 from binding to LDL receptors. After a jury determined that Sanofi failed to prove that the asserted claims were invalid for lack of enablement, the district court granted Sanofi’s post-trial motion for invalidity based on lack of enablement. The US Court of Appeals for the Federal Circuit affirmed, finding that the scope of the claims encompassed millions of antibodies and that the patent thus did not meet the enablement requirement because practicing the full scope of the claims would require “undue experimentation.”

The Supreme Court declined to consider the first question presented in Amgen’s petition: whether enablement should be a question of law (under current Federal Circuit precedent) or be designated a question of fact to be decided by a jury. In granting certiorari, the Supreme Court proceeded contrary to the recommendation of the US Solicitor General.

Don’t Stand for It—Collateral Estoppel and Standing

by | Nov 10, 2022 |

In a series of related cases, the US Court of Appeals for the Federal Circuit affirmed two decisions from the US District Court for the District of Delaware regarding collateral estoppel on standing issues and reversed a decision from the US District Court for the Northern District of California regarding the effect of license termination on standing. Uniloc 2017 LLC v. Google LLC, Case No. 21-1498 (Fed. Cir. Nov. 4, 2022) (Lourie, Dyk, Hughes, JJ.); Uniloc USA, Inc. v. Motorola Mobility LLC, Case No. 21-1555 & Uniloc LLC v. Blackboard Inc., Case No. 21-1795 (Fed. Cir. Nov. 4, 2022) (Lourie, Dyk, Hughes, JJ.)

These actions arose out of a series of patent suits filed by various Uniloc entities against tech companies in the Eastern District of Texas, the Western District of Texas and the District of Delaware involving several different patents. The Eastern District of Texas case against Google was transferred to the Northern District of California, and the Western District of Texas case against Blackboard was transferred to the District of Delaware. All three cases were dismissed for lack of standing due to a prior license agreement.

In 2014, a Uniloc entity entered into a Revenue Sharing and Note and Warrant Purchase Agreement with Fortress regarding a loan Fortress made to Uniloc. Under the terms of this agreement, if Uniloc defaulted, Fortress would receive a royalty-free license with the ability to sublicense. Uniloc defaulted in March 2017. In May 2018, Uniloc and Fortress entered into a Payoff and Termination Agreement, which explicitly terminated the patent licenses.

Uniloc sued several companies, including Motorola, Blackboard and Apple, in the period between the default and the Termination Agreement. In the Apple case, the district court found Uniloc lacked standing because it had granted a royalty-free license with the ability to sublicense to Fortress. The cases involving Motorola and Blackboard were subsequently dismissed for lack of standing. Uniloc appealed the decision in the Apple case but later settled with Apple. The settlement did not address vacatur of the district court decision. When Uniloc appealed the Motorola and Blackboard decisions, Motorola and Blackboard raised collateral estoppel. Given the virtually identical factual circumstances, the Federal Circuit held that collateral estoppel applied and that Uniloc could not relitigate the standing issues.

Unlike the cases involving Motorola and Blackboard, Uniloc filed the action against Google after it entered into the Termination Agreement with Fortress. At the district court, Google argued that Uniloc lacked standing because the Termination Agreement could not terminate the irrevocable license provision and that as a consequence of the grant under the Termination Agreement Uniloc lacked standing. Applying New York law (as the law governing the contract), the district court held that the Termination Agreement could not terminate the irrevocable license and therefore dismissed the case for lack of standing. The Federal Circuit, reviewing the issue of law de novo, held that “irrevocable” referred to whether Uniloc could unilaterally terminate an agreement, and not to whether the parties could mutually agree to terminate the [...]

Ordinary Observer Conducts Product-by-Product Analysis in View of Prior Art

by | Nov 3, 2022 |

In one of two concurrent opinions concerning the same design patent case, the US Court of Appeals for the Federal Circuit vacated a district court’s entry of a preliminary injunction after concluding that the court had failed to properly consider the accused products separately and in view of the prior art when determining the plaintiffs’ likelihood of success. ABC Corp. I v. P’ship & Unincorporated Ass’ns Identified on Schedule “A”, Case No. 22-1071 (Fed. Cir. Oct. 28, 2022) (Dyk, Taranto, Stoll, JJ.)

Hangzhou Chic Intelligent Technology and Unicorn Global (collectively, the plaintiffs) own four patents claiming designs for handle-less, two-wheeled, motorized, stand-on vehicles commonly referred to as “hoverboards.” Urbanmax, GaodeshangUS, Gyroor-US, Fengchi-US, Jiangyou-US, Gyroshoes and HGSM (collectively, the appellants) sell Gyroor-branded hoverboards. In 2020, the plaintiffs sued the appellants for patent infringement and sought a temporary restraining order and a preliminary injunction. As explained here, the district court granted the preliminary injunction in 2020, but thereafter invited the plaintiffs to file a second motion for a preliminary injunction in light of unsuccessful motions by Fengchi-US, Urbanmax and Gyroor-US to dissolve the 2020 preliminary injunction for lack of notice under Fed. R. Civ. P. 65(a). Heeding the court’s advice, the plaintiffs filed a motion for a second preliminary injunction on August 24, 2021.

The primary issue before the district court concerning the 2021 preliminary injunction was whether the plaintiffs had demonstrated a likelihood of success on the merits that the accused products infringed the plaintiffs’ patents in light of certain prior art hoverboards. The prior art included a hoverboard with an hourglass-shaped body, which was a significant feature of the patented designs and the majority of the accused products. Despite the similarities between the prior art board and the claimed designs, the plaintiffs generally disregarded the prior art in their analysis. After comparing the four accused products as a group to the claimed designs, the plaintiffs’ expert opined that the accused products infringed the asserted patents based in large part on their similar hourglass bodies, in addition to other features.

The appellants’ expert countered that “the attention of the hypothetical ordinary observer will be drawn to those aspects of the claimed design that differ from the prior art,” rather than the hourglass shape, and that the additional ornamental features of the accused products were not substantially similar to the claimed designs. While the district court acknowledged that “resolving this expert dispute will likely require a trial,” it nonetheless concluded that the plaintiffs had demonstrated likelihood of success and entered the preliminary injunction order. The appellants filed a notice of appeal.

On appeal, the Federal Circuit concluded that the lower court had erred in four material respects:

  • Applying the wrong legal standard
  • Failing to conduct the ordinary observer analysis in view of the prior art
  • Failing to apply the ordinary observer analysis on a product-by-product basis
  • Crafting an overbroad injunction.

First, the Federal Circuit took issue with the district court’s entry of a preliminary injunction despite its [...]

Heads Up: Defendants Deserve Fair Notice of Preliminary Injunctions

by | Nov 3, 2022 |

In one of two concurrent opinions concerning the same design patent case, the US Court of Appeals for the Federal Circuit vacated a district court’s grant of a preliminary injunction and an order extending the preliminary injunction to new defendants for lack of notice under Rule 65(a). ABC Corp. I v. P’ship & Unincorporated Ass’ns Identified on Schedule “A”, Case No. 21-2150 (Fed. Cir. Oct. 28, 2022) (Taranto, Dyk, Stoll, JJ.)

On August 17, 2020, ABC Corporation I and ABC Corporation II (collectively, ABC) brought a design patent infringement action asserting four “hoverboard” design patents against several online merchants. The ABC patents claim designs for handle-less, two-wheeled, motorized, stand-on vehicles commonly referred to as hoverboards. Attached to its original and amended complaints, ABC provided a list of defendants in a Schedule A that was amended throughout the proceedings as new defendants were identified. Gyroor-US was an originally named defendant on Schedule A, but it was not served with the complaint and summons until January 29, 2021.

On November 24, 2020, the district court granted ABC’s November 20, 2020, motion for a preliminary injunction against the defendants then listed on Schedule A, including Gyroor-US, which had not yet been served and was not given notice of the motion under Fed. R. Civ. P. 65(a). On May 24, 2021, the court also granted ABC’s May 6, 2021, motion to amend Schedule A to add GaodeshangUS, Fengchi-US and Urbanmax, binding them to the 2020 preliminary injunction even though they too had not received Rule 65(a) notice and were not served with process until June 25, 2021. GaodeshangUS filed a notice of appeal immediately following the court’s May 24 order. After several unsuccessful motions to vacate the 2020 preliminary injunction for lack of notice, Fengchi-US, Urbanmax and Gyroor-US also filed notices of appeal.

The Federal Circuit first determined that it had jurisdiction to hear the three appeals by GaodeshangUS, Fengchi-US, Urbanmax and Gyroor-US under 28 U.S.C. § 1292(c)(1), which grants the Federal Circuit exclusive jurisdiction of an appeal from an “interlocutory order[] . . . granting, continuing, modifying, refusing or dissolving [an] injunction[], or refusing to dissolve or modify [an] injunction[]” in any case over which the Federal Circuit would have jurisdiction of an appeal under 28 U.S.C. § 1295, such as cases arising under the patent laws. The Court began by considering GaodeshangUS’s May 24, 2021, notice of appeal, which stated that the appeal was from the preliminary injunction “entered in this action on November 24, 2021 [sic],” rather than the May 24, 2021, order. The parties disputed whether GaodeshangUS’s notice of appeal was timely filed within 30 days of the relevant order and whether the May 24 order was appealable as a modification of the 2020 preliminary injunction. The Federal Circuit concluded that GaodeshangUS’s appeal should be interpreted to refer to the May 24 order because it was filed on the same day as the order and “a mistake in designating the judgment appealed from” is not fatal if “the intent to [...]

Does Not Compute: Faster Processes Aren’t Enough for Subject Matter Eligibility

by | Oct 27, 2022 |

In yet another opinion addressing subject matter eligibility and application of the Supreme Court’s Alice decision, the US Court of Appeals for the Federal Circuit found claims directed to graphical displays and user interfaces subject matter ineligible as directed to abstract ideas. IBM v. Zillow Group, Inc., Case No. 21-2350 (Fed. Cir. Oct. 13, 2022) (Reyna, Hughes, Stoll, JJ.) (Stoll, J., dissenting in part).

IBM sued Zillow for allegedly infringing several patents related to graphical display technology. The district court granted Zillow’s motion for judgment on the pleadings that sought a ruling that two of the asserted patents claimed patent-ineligible subject matter under 35 U.S.C. § 101. IBM appealed.

On appeal, the Federal Circuit applied the Alice two-step analysis to determine whether the claims at issue were directed to a patent-ineligible concept, such as an abstract idea, and if so, whether additional claim elements (considering each element both individually and as an ordered combination) transformed the nature of the claim into a patent-eligible application. As discussed in the Supreme Court Alice and Mayo decisions, the second step is “a search for an ‘inventive concept’—i.e., an element or combination of elements that is ‘sufficient to ensure that the patent in practice amounts to significantly more than a patent upon the [ineligible concept] itself.’”

The representative claim of the first patent was directed to a method for coordinated geospatial and list-based mapping, and the method steps recited viewing elements having “geospatial characteristics” in a given viewing area of a map space and displaying a list of the elements in that space. The user then draws a selected area within the map space, having elements that may be inside or outside of the selected area. The elements having the geospatial characteristics within the selection area are selected and those outside the selected area are deselected. The map display and the list are then synchronized and concurrently updated to reflect what has been selected and deselected.

The district court concluded that “the patent was directed to the abstract idea of responding to a user’s selection of a portion of a displayed map by simultaneously updating the map and a co-displayed list of items on the map,” reasoning that the claimed method could be performed manually, for example, by putting a transparent overlay on a printed map, drawing on it with a marker, and then blocking off the “unselected area” of the map and corresponding list items with opaque paper cut to appropriate sizes. To choose a different “selection area,” the user would erase the prior markings, remove the paper and start over. The district court noted that “alterations to hardcopy materials were made or auditioned in this manner” long before computers, and concluded that “[t]he [] patent merely contemplates automation using a computer.”

The Federal Circuit agreed that the claims failed to recite any inventive technology for improving computers as tools and were instead directed to an abstract idea for which computers were invoked merely to limit and coordinate the display of information based [...]

Color Me Unsurprised: No Preclusion of Plaintiff’s Claims

by | Oct 27, 2022 |

The US Court of Appeals for the Seventh Circuit reversed the lower court’s order determining that the plaintiff’s federal lawsuit was barred under the doctrines of claim and issue preclusion, noting an Illinois law exception on claim preclusion and finding no issue preclusion. Creation Supply, Inc. v. Selective Ins. Co. of the Southeast, Case No. 21-3172 (7th Cir. Oct. 19, 2022) (Rovner, Hamilton, Scudder, JJ.)

Creation Supply is a producer of markers. In 2012 one of its competitors sued it for trademark violations. Creation requested that Selective Insurance provide coverage for the lawsuit, but Selective refused. Creation entered into a settlement agreement with its competitor that prevented Creation from selling one of its primary lines of markers. As a result, Creation lost much of its business and struggled financially.

Selective did not provide coverage for Creation’s legal defense. It also sought a declaration in Illinois state court that it owed Creation no duty to defend. Creation countersued, seeking a declaration that Selective did owe it a duty to defend. Creation also alleged that Selective breached the insurance policy between the parties. The Illinois circuit court entered partial summary judgment for Creation on its duty to defend the claim and finalized an award of incidental relief in October 2017.

In 2014, during the state court litigation, Creation filed a suit against Selective in federal court for breach of contract and a claim under the Illinois Insurance Code for vexatious and unreasonable conduct. In 2016, Creation requested voluntary dismissal of the state court breach of contract claim. The Illinois circuit court granted the motion and expressly reserved Creation’s right to maintain its federal action on its breach of contract claim. After the end of the state court litigation in 2017, the federal court case continued. The district court granted summary judgment for Creation on the insurance coverage question. After a bench trial on the Illinois Insurance Code claim, the court found for Creation and awarded almost $3 million in damages. On appeal, the Seventh Circuit reversed and remanded, instructing the district court to resolve the remaining issue of contract damages.

After the remand, Creation sought to amend the complaint to seek punitive damages. The district court denied that request. Selective then moved for judgment on the pleadings, contending that the doctrines of claim and issue preclusion barred Creation’s remaining contract claim. The district court agreed and entered judgment for Selective because the Illinois state courts had resolved the issue of Selective’s duty to defend. Creation appealed.

The Seventh Circuit affirmed the district court’s denial of Creation’s leave to amend, then turned to the issue of claim preclusion, a legal doctrine that prevents a party from repeatedly litigating the same cause of action against the same adverse party. Claim preclusion requires the following:

  • A court with proper jurisdiction must have issued a final judgment on the merits.
  • The claims in the two actions must be the same.
  • The parties in the second action must be the same (or in privity with) those [...]

Establishing Indefiniteness Requires More Than Identifying “Unanswered Questions” Part II

by | Oct 27, 2022 |

Earlier this year, the US Court of Appeals for the Federal Circuit reversed a district court decision for relying on an incorrect standard for indefiniteness. (Nature Simulation Systems Inc. v. Autodesk, Inc). Now, in response to a motion for panel rehearing, the Federal Circuit modified its decision on rehearing deleting language. Nature Simulation Systems Inc. v. Autodesk, Inc., Case No. 20-2257 (Fed. Cir. Oct. 17, 2022) (Lourie, Dyk, Newman JJ.) (Dyk, J., dissenting)

Nature Simulations Systems asserted two patents against Autodesk (one a continuation-in-part of the other), both entitled “Method for Immediate Boolean Operations Using Geometric Facets.” According to the patents, the claimed methods are improvements upon a “Watson” method known in the prior art. The district court concluded that two terms—“searching neighboring triangles of the last triangle pair that holds the last intersection point” and “modified Watson method”—were invalid as indefinite based on “unanswered questions” regarding the scope of the claims posed by Autodesk’s expert. In the first reported decision, the Federal Circuit reversed. The Court held that the “unanswered questions” analysis used an incorrect legal standard, citing the specification as clarifying the scope of the claims and citing case law on deference to US Patent & Trademark Office examiners.

Following rehearing, the Federal Circuit slightly modified its decision in two primary ways but maintained its reversal of the district court’s ruling on indefiniteness.

First, the Federal Circuit added an explanation regarding how the specification answers the questions raised by Autodesk. The Court stated that “the language that the court stated ‘is not contained in the claim language’ is in the specification,” and cited a flowchart and accompanying description in the patent. The Court found fault in Autodesk’s argument because “[t]he claims set forth the metes and bounds of the invention; they are not intended to repeat the detailed operation of the method as described in the specification.”

Second, the Federal Circuit backed away from its previous reliance on deference to the examiner. In its earlier decision, the Court explained that the examiner had issued rejections for indefiniteness but withdrew them after amendments to the claims. The Court then spent a little over a page of the opinion explaining that, as official agency actors experienced in the technology and legal requirements for patentability, patent examiners are entitled to “appropriate deference.” Following rehearing, the Court removed the portion of the opinion addressing examiner deference entirely while maintaining the criticism that the district court gave “no weight to the prosecution history showing the resolution of indefiniteness by adding the designated technologic limitations to the claims.” In support, the Court cited cases holding that claims are construed in light of the specification and file history from the perspective of skilled artisans.

Judge Dyk again dissented, stating that “[t]he fact that a patent examiner introduced the indefinite language does not absolve the claims from the requirements of 35 U.S.C. § 112.” Judge Dyk argued that far from adopting a flawed “unanswered questions” analysis, the district court’s analysis was detailed and [...]
