In Powerblock Holdings, Inc. v. IFIT, Inc., the Federal Circuit recently analyzed a straightforward mechanical invention under 35 U.S.C. § 101 and clarified the analysis that should be used when a § 101 challenge to a claim is raised.
Powerblock Holdings, Inc. sued IFIT, Inc. in the District Court of Utah for infringement of U.S. Patent 7,578,771, which covers weight selection and adjustment systems for dumbbells. The patent disclosed and claimed a system that allows a user to move a selector to a desired weight for a dumbbell and then through interaction of stacked weights, a dumbbell handle, and an electric motor, the desired weight is automatically added to each end of the handle of the dumbbell. The District Court found 19 of the 20 claims of the ‘771 patent invalid under § 101 as being directed to patent-ineligible subject matter. After review and analysis, the Federal Circuit reversed that finding and remanded for further proceedings.
Claims 1 and 20 of the ‘771 patent are relevant to the analysis conducted by the district court and the Federal Circuit:
1. A weight selection and adjustment system for a selectorized dumbbell, which comprises:
(a) a selectorized dumbbell, which comprises:
(i) a stack of nested left weight plates and a stack of nested right weight plates;
(ii) a handle having a left end and a right end; and
(iii) a movable selector having a plurality of different adjustment positions in which the selector may be disposed, wherein the selector is configured to couple selected numbers of left weight plates to the left end of the handle and selected numbers of right weight plates to the right end of the handle with the selected numbers of coupled weight plates differing depending upon the adjustment position in which the selector is disposed, thereby allowing a user to select for use a desired exercise weight to be provided by the selectorized dumbbell; and
(b) an electric motor that is operatively connected to the selector at least whenever a weight adjustment operation takes place, wherein the electric motor when energized from a source of electric power physically moves the selector into the adjustment position corresponding to the desired exercise weight that was selected for use by the user.
20. A weight selection and adjustment system for a dumbbell, which comprises:
(a) a dumbbell that provides an exercise weight that is lifted by a user when the user grips and lifts a handle of the dumbbell, wherein the exercise weight provided by the dumbbell is adjustable by coupling more or fewer weight plates to each end of the handle;
(b) an electric motor that may be selectively energized and when energized will cause a desired number of weight plates to be coupled to each end of the handle; and
(c) a data entry device to allow the user to input a weight selection decision that operatively controls the energization of the motor to adjust the exercise weight of the dumbbell in accordance with the weight selection decision input into the data entry device by the user.
The District Court selected claim 20[1] as representative of the claims in the patent and used that claim to conduct its § 101 analysis. The court applied the two-step § 101 analysis established by the Supreme Court in Alice Corp. Pty. Ltd. v. CLS Bank Int’l., 573 U.S. 208 (2014). The first step of the Alice analysis considers whether the claims are directed to excluded subject matter under § 101—that is, whether the claims act to preempt an abstract idea or concept, or whether the claims are directed to a specific means or method for achieving the claim’s goals. The Defendant argued at the District Court that the claims were directed towards an end result—automating the prior art process of selecting and adding weights to a dumbbell—and the Plaintiff argued that the claims cover an improved weight selection and adjustment mechanism and not an abstract idea. To support its argument, the Plaintiff pointed to three distinct elements of claim 20: a dumbbell, an electric motor to cause weights to be applied to the dumbbell, and a data entry device for a user to input weight selection information.
After analysis, the District Court concluded that claim 20 was impermissibly broad and outcome-oriented in construction. The court pointed out that the structural elements described in the claim were three well known components, that the claim language describes an end result, causing weights to be added to a dumbbell, and that the claim would cover all or substantially all systems for automated dumbbell plate stacking using electric motors and data entry systems. As a result, the Court concluded that claim 20 was directed to patent-ineligible subject matter.
Moving to step 2 of the Alice test, the District Court considered whether the claim elements added sufficient information to identify an inventive concept in the application of the ineligible subject matter to which the claim is directed. The District Court noted that adding conventional steps at a high level of generality is not enough to supply an inventive concept. The court observed that the patent is directed to a straightforward assembly of generic machinery employed in a conventional way. The District Court also noted that the benefits conveyed by the claimed invention are conferred by the simple fact of automation and the removal of errors sometimes caused by human operators.
The Court thus concluded that claims 1-18 and 20[2] described using conventional components in a conventional manner to automate a known mechanical process and thus were not directed to statutory subject matter under § 101.
On Appeal the Federal Circuit chose claim 1 for its initial analysis of the § 101 issue. The court described its focus under Alice step 1 as whether the claims focus on a specific means or method that improves the relevant technology or are instead directed to a result or effect that is an abstract idea and merely invoke generic processes and machinery to obtain that result.
The Federal Circuit concluded that the District Court erred in its conclusion that that the claims were directed to the abstract idea of automating weight stacking. The Federal Circuit agreed that the claims were broad but disagreed that they did not provide any meaningful limitations on how to accomplish automatic weight stacking. Because the claims did contain structural limitations on how the claimed device operated, the claims would not preempt all such systems.
In its analysis, the Federal Circuit pointed out that claim 1 is limited to a particular type of dumbbell—a selectorized dumbbell with a stack of nested left weight plates, a stack of nested right weight plates, a handle, and a movable selector with different adjustment positions. The claim also requires an electric motor that is operatively connected to the selector and acts to move the selector into different positions depending on user input. Because of these specific technical requirements found in the claim, the Federal Circuit concluded that the claim satisfies § 101. The Federal Circuit found that the claim “goes beyond claiming the ‘broad concept’ of automating a known technique” and instead provides a specific manner of performing the technique. The Federal Circuit distinguished this case from earlier cases where claims were found to not comply with § 101 by explaining that in those cases the claims did not contain specific technical requirements reflected as claim limitations but instead were directed to broad statements of operation.
Importantly, the Federal Circuit specifically addressed the Defendant’s argument that because the elements identified by the claims are conventional in the prior art, the claim simply covers automating what was previously a manual process. First , the Federal Circuit pointed out that Alice step one requires analysis of the claims in their entirety to determine whether they are directed to patentable subject matter. The Court then cautioned that courts must take care not to oversimplify claims when considering the Alice step one question, pointing out that all inventions at some level use, apply, or rely upon laws of nature to operate. The Federal Circuit identified the specific claim elements that added sufficient specificity to pass muster under § 101—an electric motor, left and right weight plates, and a dumbbell handle which is configured to receive those plates.
In footnote 3 to the opinion, the Federal Circuit stated that the subject matter requirement of § 101 should not be conflated with the novelty and obviousness requirement of §§ 102 and 103. In the past, parties and courts have sometimes made this error, arguing that because the individual elements of a claim are known, assembling them into an automated system does not satisfy § 101 because the claim only covers automation of a prior known product or process. The Panel quoted from Parker v. Flook, 437 U.S. 584, 593 (1978) to support the idea that the determination of whether a claim covers statutory subject matter must be made before considering whether the claim is new or obvious.
Conclusion
When considering whether a claim passes muster under § 101 it is important to consider the totality of the challenged claim—does it define a specific structure or process that distinguishes the claim from an abstract statement of structure or function which might preempt all other ways of achieving the claimed subject matter? It is important to recognize that although the various elements of a claim may be known in the art individually, their assembly into an automated system does not by itself indicate that the claim is invalid under § 101. The analysis under § 101 should focus on whether the claim contains sufficient detail to define a specific invention rather than preempt an abstract idea.
[1] The Court selected claim 20 because it had been identified in the complaint as an infringed claim, and because the plaintiff’s claim chart and briefing had focused on that claim.
[2] The District Court noted that claim 19 was a “means plus function” claim and thus arguably included more structure from the specification and drawings, which perhaps resulted in its passing muster under § 101.
