American Axle & Manufacturing, Inc. v. Neapco Holdings, LLC
October 9, 2019
Opinion by: Dyke, Moore and Taranto (October 3, 2019).
Dissent by: Moore.
Summary:
American Axle & Manufacturing, Inc. (AAM) sued Neapco Holdings, LLC (Neapco) for alleged infringement of U.S. Patent 7,774,911 for a method of manufacturing driveline propeller shafts for automotive vehicles. On appeal, the Federal Circuit upheld the District Court of Delaware’s holding of invalidity under 35 U.S.C. 101. The Federal Circuit explained that the claims of the patent were directed to the desired “result” to be achieved and not to the “means” for achieving the desired result, and, thus, held that the claims failed to recite a practical way of applying underlying natural law (e.g., Hooke’s law related to vibration and damping), but were instead drafted in a results-oriented manner that improperly amounted to encompassing the natural law.
Details:
- Background
The case relates to U.S. Patent 7,774,911 of American Axle & Manufacturing, Inc. (AAM) which relates to a method for manufacturing driveline propeller shafts (“propshafts”) with liners that are designed to attenuate vibrations transmitted through a shaft assembly. Propshafts are employed in automotive vehicles to transmit rotary power in a driveline. During use, propshafts are subject to excitation or vibration sources that can cause them to vibrate in three modes: bending mode, torsion mode, and shell mode.
The CAFC focused on independent claims 1 and 22 as being “representative” claims, noting that AAM “did not argue before the district court that the dependent claims change the outcome of the eligibility analysis.”
| Claim 1 | Claim 22 |
| 1. A method for manufacturing a shaft assembly of a driveline system, the driveline system further including a first driveline component and a second driveline component, the shaft assembly being adapted to transmit torque between the first driveline component and the second driveline component, the method comprising: providing a hollow shaft member; tuning at least one liner to attenuate at least two types of vibration transmitted through the shaft member; and positioning the at least one liner within the shaft member such that the at least one liner is configured to damp shell mode vibrations in the shaft member by an amount that is greater than or equal to about 2%, and the at least one liner is also configured to damp bending mode vibrations in the shaft member, the at least one liner being tuned to within about ±20% of a bending mode natural frequency of the shaft assembly as installed in the driveline system. | 22. A method for manufacturing a shaft assembly of a driveline system, the driveline system further including a first driveline component and a second driveline component, the shaft assembly being adapted to transmit torque between the first driveline component and the second driveline component, the method comprising: providing a hollow shaft member; tuning a mass and a stiffness of at least one liner, and inserting the at least one liner into the shaft member; wherein the at least one liner is a tuned resistive absorber for attenuating shell mode vibrations and wherein the at least one liner is a tuned reactive absorber for attenuating bending mode vibrations. |
As explained by the CAFC, “[i]t was known in the prior art to alter the mass and stiffness of liners to alter their frequencies to produce dampening,” and “[a]ccording to the ’911 patent’s specification, prior art liners, weights, and dampers that were designed to individually attenuate each of the three propshaft vibration modes — bending, shell, and torsion — already existed.” The court further explained that in the ‘911 patent “these prior art damping methods were assertedly not suitable for attenuating two vibration modes simultaneously,” i.e., “shell mode vibration [and] bending mode vibration,” but “[n]either the claims nor the specification [of the ‘911 patent] describes how to achieve such tuning.”
The District Court concluded that the claims were directed to laws of nature: Hooke’s law and friction damping. And, the District Court held that the claims were ineligible under 35 U.S.C. 101. AAM appealed.
- The CAFC’s Decision
Under 35 U.S.C. 101, “any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof” may be eligible to obtain a patent, with the exception long recognized by the Supreme Court that “laws of nature, natural phenomena, and abstract ideas are not patentable.”
Under the Supreme Court’s Mayo and Alice test, a 101 analysis follows a two-step process. First, the court asks whether the claims are directed to a law of nature, natural phenomenon, or abstract idea. Second, if the claims are so directed, the court asks whether the claims embody some “inventive concept” – i.e., “whether the claims contain 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.”
At step-one, the CAFC explained that to determine what the claims are directed to, the court focuses on the “claimed advance.” In that regard, the CAFC noted that the ‘911 patent discloses a method of manufacturing a driveline propshaft containing a liner designed such that its frequencies attenuate two modes of vibration simultaneously. The CAFC also noted that AAM “agrees that the selection of frequencies for the liners to damp the vibrations of the propshaft at least in part involves an application of Hooke’s law, which is a natural law that mathematically relates mass and/or stiffness of an object to the frequency that it vibrates. However, the CAFC also noted that “[a]t the same time, the patent claims do not describe a specific method for applying Hooke’s law in this context.”
The CAFC also noted that “even the patent specification recites only a nonexclusive list of variables that can be altered to change the frequencies,” but the CAFC emphasized that “the claims do not instruct how the variables would need to be changed to produce the multiple frequencies required to achieve a dual-damping result, or to tune a liner to dampen bending mode vibrations.”
The CAFC explained that “the claims general instruction to tune a liner amounts to no more than a directive to use one’s knowledge of Hooke’s law, and possibly other natural laws, to engage in an ad hoc trial-and-error process … until a desired result is achieved.”
The CAFC explained that the “distinction between results and means is fundamental to the step 1 eligibility analysis, including law-of-nature cases.” The court emphasized that “claims failed to recite a practical way of applying an underlying idea and instead were drafted in such a results-oriented way that they amounted to encompassing the [natural law] no matter how implemented.
At step-two, the CAFC stated that “nothing in the claims qualifies as an ‘inventive concept’ to transform the claims into patent eligible matter.” The CAFC explained that “this direction to engage in a conventional, unbounded trial-and-error process does not make a patent eligible invention, even if the desired result … would be new and unconventional.” As the claims “describe a desired result but do not instruct how the liner is tuned to accomplish that result,” the CAFC affirmed that the claims are not eligible under step two.
NOTE: In response to Judge Moore’s dissent, the CAFC explained that the dissent “suggests that the failure of the claims to designate how to achieve the desired result is exclusively an issue of enablement.” However, the CAFC expressed that “section 101 serves a different function than enablement” and asserted that “to shift the patent-eligibility inquiry entirely to later statutory sections risks creating greater legal uncertainty, while assuming that those sections can do work that they are not equipped to do.”
- Judge Moore’s Dissent
Judge Moore strongly dissented against the majority’s opinion. Judge Moore argued, for example, that:
- “The majority’s decision expands § 101 well beyond its statutory gate-keeping function and the role of this appellate court well beyond its authority.”
- “The majority’s concern with the claims at issue has nothing to do with a natural law and its preemption and everything to do with concern that the claims are not enabled. Respectfully, there is a clear and explicit statutory section for enablement, § 112. We cannot convert § 101 into a panacea for every concern we have over an invention’s patentability.”
- “Section 101 is monstrous enough, it cannot be that now you need not even identify the precise natural law which the claims are purportedly directed to.” “The majority holds that they are directed to some unarticulated number of possible natural laws apparently smushed together and thus ineligible under § 101.”
- “The majority’s validity goulash is troubling and inconsistent with the patent statute and precedent. The majority worries about result-oriented claiming; I am worried about result-oriented judicial action.”
Takeaways:
- When drafting claims, be mindful to avoid drafting a “result-oriented” claim that merely recites a desired “result” of a natural law or natural phenomenon without including specific steps or details setting establishing “how” the results are achieved.
- When drafting claims, be mindful that although under 35 U.S.C. 112 supportive details satisfying enablement are only required to be within the written specification, under 35 U.S.C. 101 supportive details satisfying eligibility must be within the claims themselves.
What’s a tool? What is functionality? Network monitoring claim held patent-eligible in split opinion

SRI International, Inc., v. Cisco Systems, Inc.
March 20, 2019
Before Lourie, O’Malley, and Stoll. Opinion by Stoll. Dissenting opinion by Lourie.
Summary
The CAFC affirmed a district court decision holding that claims related to network security monitoring are patent-eligible. In the 2-1 opinion, the CAFC held that all of the asserted claims are patent eligible under §101 as not “directed to” an abstract idea under the first step of the Alice test, because the claims focus on an improvement in the functionality of computers and computer network technology.
The CAFC also affirmed the district court’s construction of the claim term “network traffic data,” summary judgment of no anticipation, and award of ongoing royalties but willful infringement and attorneys’ fees issues were vacated and remanded.
This presentation only addresses the issue of patent eligibility.
Details
SRI International, Inc. (“SRI”) sued Cisco Systems, Inc. (“Cisco”) for infringement of U.S. Patent Nos. 6,711,615 (‘615 patent) and 6,484,203 (‘203 patent). The ‘615 patent is a continuation of the ‘203 patent. The patents relate to network security by using network monitors to analyze the data on the network and generating and integrating reports of suspicious activity.
SRI proposed claim 1 of the ‘615 patent as representative claim while Cisco proposed claim 1 of the ‘203 patent. The CAFC noted that the claims are substantially similar, the difference in the list of categories of data not being material to any issue on appeal, and adopted claim 1 of ‘615 patent as the representative claim.
Claim 1 of the ‘615 patent:
1. A computer-automated method of hierarchical event monitoring and analysis within an enterprise network comprising:
deploying a plurality of network monitors in the enterprise network;
detecting, by the network monitors, suspicious network activity based on analysis of network traffic data selected from one or more of the following categories: {network packet data transfer commands, network packet data transfer errors, network packet data volume, network connection requests, network connection denials, error codes included in a network packet, network connection acknowledgements, and network packets indicative of well-known network-service protocols};
generating, by the monitors, reports of said suspicious activity; and
automatically receiving and integrating the reports of suspicious activity, by one or more hierarchical monitors.
As a preliminary matter, the CAFC noted that SRI spent considerable investment on network intrusion detection and developed the Event Monitoring Enabling Response or Anomalous Live Disturbances (“EMERALD”) project prior to the filing of the patents. In addition, the CAFC also noted that the Defense Advanced Research Projects Agency of the Department of Defense, which helped fund the project, called it a “gem in the world of cyber defense” and “‘a quantum leap improvement over’ previous technology.”
As to the issue of patent eligibility, the District Court held that the claims do more than merely recite the performance of a known business practice on the Internet and are better understood as being necessarily rooted in computer technology in order to solve a specific problem in the realm of computer networks. The CAFC agreed.
The CAFC explained that by the recitation of detecting an activity, receiving and integrating the reports, the claim does more than just the normal, expected operation of a conventional computer network. The CAFC specifically described the technological improvement as “a network defense system that monitors network traffic in real-time to automatically detect large-scale attacks,” with reference to Enfish, LLC v. Microsoft Corp.
In addition, the CAFC noted that the specification provided an explanation of both the technological problem – the network becomes more valuable when the technology become more interoperable and integrated but also makes it more vulnerable to attack – and the technological solution, by providing “a framework for the recognition of more global threats to interdomain connectivity, including coordinated attempts to infiltrate or destroy connectivity across an entire network enterprise.” Unfortunately, here, the CAFC simply cited the specification of the SRI patent but did not provide any details regarding how the specification presents the technological solution in relation to the claim language.
When arguing that the claims are directed to an abstract idea, Cisco had raised three main arguments, which the CAFC addressed in turn:
1. the claims are “directed to generic steps required to collect and analyze data,” therefore, “the claims are analogous to those in Electric Power Group, LLC v. Alstom S.A.” in which the claims were simply using the computers as tools. Thus, “the claims are directed to an abstract idea”;
2. “the invention does not involve an improvement to computer functionality itself”; and
3. the claims correspond generally to what people can “go through in their minds”.
Regarding Cisco’s first argument, the CAFC disagreed with Cisco’s view that the SRI patent claims are similar to the claims in Electric Power Group,[i] because the claimed invention in Electric Power Group was only “using computers as tools to solve a power grid problem.” The CAFC emphasized that the claims are similar to the claims in DDR Holdings, LLC v. Hotels.com, which were “directed to more than merely requiring a computer network operating in is normal, expected manner.”
Next, in rejecting Cisco’s second argument, the CAFC asserted that the representative claim is not about “automating a conventional idea on a computer” but “improv[ing] the technical functioning of the computer and computer networks by reciting a specific technique for improving computer network security.”
The CAFC also rejected Cisco’s third argument that the claims recite a mental process, by countering that “the human mind is not equipped to detect suspicious activity by using network monitors and analyzing network packets.”
In conclusion, the CAFC held that the claims at issue are not “directed to” an abstract idea under step one of Alice, because the claims are not just using the computer as a tool to analyze data from multiple sources to detect suspicious activity. Instead, the claims define using network monitors to detect suspicious network activity based on analysis of network traffic data, generating reports of that suspicious activity, and integrating those reports using hierarchical monitors to identify hackers and potential intruders. Thus, the claims provide an improvement in the functionality of computers and computer networks, and, therefore, the claims are patent eligible.
Dissent
Dissenting Judge Lourie thought that the claims of the SRI patent were similar to the claims in Electric Power Group because, in his view, the SRI claims “recite nothing more than deploying network monitors, detecting suspicious network activity, and generating and handling reports.” Judge Lourie noted that in Electric Power Group, the claims that were held patent-ineligible recited “receiving data,” “detecting and analyzing events in real time,” “displaying the event analysis results and diagnoses of events,” “accumulating and updating measurements,” and “deriving a composite indicator of reliability.”
Further, he pointed out that the portions of the SRI specification to which the majority refers “only recites results, not means for accomplishing them,” and that the SRI claims as written “do not recite a specific way of enabling a computer to monitor network activity.” Since he considered that the SRI claims do not provide any specifics as to how the steps are performed and show no improvement to computer technology, he would have held that the claims were directed to an abstract idea.
Takeaway
As this decision shows, there is much uncertainty regarding whether a claim would be treated as patent-eligible or not under the Alice test. It seems that a different set of judges might have easily sided with Judge Lourie’s analysis and invalidated the claims.
In the
meantime, the explanations and details given in the patent description
regarding the technical problem solved by the invention, instead of referring
to generic computer or network components, helped these claims survive the
patent-eligibility challenge.
[i] Claim 12 of U.S. Patent 8,401,701 at issue in Electric Power Group, LLC v. Alstom S.A.:
12. A method of detecting events on an interconnected electric power grid in real time over a wide area and automatically analyzing the events on the interconnected electric power grid, the method comprising:

The limitations of a “wherein” clause

Allergan Sales, LLC v. Sandoz, Inc., No. 2018-2207
August 29, 2019
Prost, Newman and Wallach. Opinion by Wallach
Summary
Appellees (Allergan hereon in) sued Appellants (Sandoz hereon in) asserting that their Abbreviated New Drug Application (ANDA) for a generic version of Allergan’s ophthalmic drug (Combigan®) infringed on their U.S. Patent Nos. 9,770,453: 9,907,801: 9,907,802. The District Court found limiting a number of “wherein” clauses in the Patents’ and granted Allergan’s motion for Preliminary Injection. Sandoz appealed. CAFC affirmed.
As an exemplary claim, independent claim 1 of the ‘453 patent is as follows:
A method of treating a patient with glaucoma or ocular hypertension comprising topically administering twice daily to an affected eye a single composition comprising 0.2% w/v brimonidine tartrate and 0.68% w/v timolol maleate,
wherein the method is as effective as the administration of 0.2% w/v brimonidine tartrate monotherapy three times per day and
wherein the method reduces the incidence of one o[r] more adverse events selected from the group consisting of conjunctival hyperemia, oral dryness, eye pruritus, allergic conjunctivitis, foreign body sensation, conjunctival folliculosis, and somnolence when compared to the administration of 0.2% w/v brimonidine tartrate monotherapy three times daily.
The specifications contained a clinical study, referred to as Example II, and it is the results thereof that are reflected in “the disputed “wherein” clauses (i.e., the efficacy and safety of the claimed combination).
Allergan argued that the “wherein” clauses were limiting, whereas Sandoz argued that the “wherein” clauses were not. Specifically, Sandoz argued that the “wherein” clauses “merely state the intended results” and so are not “material to patentability.” Sandoz argued that the only positive limitation in the claim[s] is the administering step. Sandoz relied upon previous cases to argue that “…whereby [or wherein] clause in a method claim is not given weight when it simply expresses the intended result of a process step positively recited.”); Bristol–Myers Squibb Co. v. Ben Venue Labs., Inc., 246 F.3d 1368, 1376 (Fed. Cir. 2001).
The District Court and CAFC disagreed. The courts looked to the specification, and to the prosecution history wherein the Applicant had relied upon the results of administering the combination drug to assert patentability over the prior art. It was also noted that the Examiner had explicitly relied upon the “wherein” clauses in his explanation as to why the claims were novel and non-obvious over the prior art in the Notice of Allowance.
The courts differentiated this case from the previous case argued by Sandoz in that, “In Bristol–Myers we expressly noted that the disputed claim terms “w[ere] voluntarily made after the examiner had already indicated . . . the claims were allowable” and such “unsolicited assertions of patentability made during prosecution do not create a material claim limitation.”
Accordingly, “the District Court “f[ound] that the ‘wherein’ clauses are limiting because they are material to patentability and express the inventive aspect of the claimed invention” and the CAFC affirmed.
Take-away
“The specification is always highly relevant to the claim construction analysis and is, in fact, the single best guide to the meaning of a disputed term.” Prosecution history and the Examiner’s express rational for allowance are also highly relevant.
WHEN FIGURES IN A DESIGN PATENT DO NOT CLEARLY SHOW AN ARTICLE OF MANUFACTURE FOR THE ORNAMENTAL DESIGN, THE TITLE AND CLAIM LANGUAGE CAN LIMIT THE SCOPE OF THE DESIGN PATENT

Curver Luxembourg, SARL, v. Home Expressions Inc.
September 12, 2019
Chen (author), Hughes, and Stoll
Summary:
The Federal Circuit affirmed the district court’s grant of a defendant’s motion to dismiss a complaint for failure to state a plausible claim of design patent infringement because when all of the drawings in a design patent at issue do not describe an article of manufacture for the ornamental design, the title, claim language, figure descriptions specifying an article of manufacture, which was amended during the prosecution of the patent based on the Examiner’s proposed amendment, can limit the scope of a design patent.
Details:
The ‘946 Patent
Curver Luxembourg, SARL (Curver) is the assignee of U.S. Design Patent No. D677,946 (‘946 patent) with a title “Pattern for a Chair” and claiming an “ornamental design for a pattern for a chair.” The ‘946 patent claims an overlapping “Y” design, as shown below. However, none of the figures illustrate a design being applied to a chair.
Prosecution
Curver originally applied for a patent directed to a pattern for “furniture,” and the original title was “FURNITURE (PART OF-).” The original claim recited a “design for a furniture part.”
However, during the prosecution, the Examiner allowed the claim but objected to the title because it was too vague to constitute an article of manufacture (in Ex Parte Quayle Action). The Examiner suggested amending the title to read “Pattern for a Chair,” and Curver accepted the Examiner’s suggestion by replacing the title with “Pattern for a Chair” and amending the claim term “furniture part” with “pattern for a chair.” Curver did not amend the figures to illustrate a chair. The Examiner accepted Curver’s amendments and allowed the application.
District Court
Home Expressions makes and sells baskets with a similar overlapping “Y” design disclosed in the ‘946 patent.
Curver sued Home Expressions accusing its basket products of infringing the ‘946 patent. Home Expressions filed a motion to discuss Curver’s complaint under Rule 12(b)(6) for failing to set forth a plausible claim of infringement.
Using a two-step analysis, the district court construed the scope of the ‘946 patent to be limited to the design pattern illustrated in the figures as applied to a chair and found that an ordinary observer would not purchase Home Expressions’s basket with “Y” design believing that the purchase was for “Y” design applied to a chair.
Therefore, the district court granted the Rule 12(b)(6) motion.
CAFC
The CAFC held that to define the scope of a design patent, the court traditionally focused on the figures illustrated in the patent. However, when all of the drawings fail to describe an article of manufacture for the ornamental design, the CAFC held that claim language specifying an article of manufacture can limit the scope of a design patent.
In addition, the CAFC uses §1.153(a) to held that “the design be tied to a particular article, but this regulation permits claim language, not just illustration along, to identify that article.”
The title of the design must designate the particular article. No description, other than a reference to the drawing, is ordinarily required. The claim shall be in formal terms to the ornamental design for the article (specifying name) as shown, or as shown and described.
The CAFC held that the prosecution history shows that Curver amended the title, claim, figure descriptions to recite “pattern for a chair” in order to satisfy the article of manufacture requirement necessary to secure its design patent. Therefore, the CAFC held that the scope of the ‘946 patent should be limited by those amendments.
Therefore, the CAFC affirmed the district court’s grant of Home Expressions’s motion to dismiss the complaint for failure to state a plausible claim of design patent infringement.
Takeaway:
- When figures in a design patent do not clearly show an article of manufacture for the ornamental design, the title and claim language can limit the scope of the design patent.
- Applicant should review the Examiner’s proposed amendments carefully before placing the application in condition for allowance.
- Applicant should be careful when crafting the title and claim language.
