II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,683,612 - "Wave Actuator"
Issued: June 20, 2017
The Invention Explained
- Problem Addressed: The patent discloses a new type of actuator, suggesting a need for novel methods to actuate an output member (Compl. ¶1; ’971 Patent, col. 1:12-14). Conventional motors often rely on complex gearboxes, whereas this invention aims for a more direct actuation mechanism.
- The Patented Solution: The invention uses a "two dimensional structure," such as a flexible disk or belt, that is pre-stressed to form a "buckling wave" ('612 Patent, Abstract). This wave is not static; a "wave propagator," such as a series of electromagnets or piezoelectric elements, causes the wave to move along the structure ('612 Patent, col. 1:25-28). An output member is in contact with this traveling wave, and the wave's movement causes the output member to move, thus providing actuation with a potentially high leverage ratio ('612 Patent, Abstract; col. 2:37-43).
- Technical Importance: The technology represents a method for creating a direct-drive motor that avoids traditional gearing by translating a propagating mechanical wave into rotational motion, which can offer advantages in simplicity, torque, and safety in robotics applications (Compl. ¶18).
Key Claims at a Glance
- The complaint does not specify which claims are asserted. Independent claim 1 is analyzed here as a representative claim.
- Independent Claim 1 recites an apparatus comprising:
- a two dimensional structure having at least a portion pre-stressed in compression... to form a wave shape having waves along the first direction;
- an output arranged in contact with the waves of the wave shape, the output and the two-dimensional structure movably arranged in relation to one another; and
- a wave propagator arranged to propagate the waves along the first direction to move the output relative to the two dimensional structure.
- The complaint does not explicitly reserve the right to assert dependent claims.
III. The Accused Instrumentality
Product Identification
- The "Genesis LiveDrive" direct-drive actuator (Compl. ¶18).
Functionality and Market Context
- The complaint alleges the Genesis LiveDrive is a "breakthrough, a direct-drive actuator with torque-to-weight that can meet or beat the best motor-gearbox actuators" (Compl. ¶18). The product is described as providing "dramatically higher speed and phenomenally greater stopping torque," which makes robots safer (Compl. ¶18). A key feature highlighted is its simplicity, with the complaint alleging it has only one moving part compared to dozens in competitive actuators, positioning it as a technology that will make robots "faster, safer and less expensive" (Compl. ¶18). The complaint includes a product description from an exhibitor page which identifies the accused product. This visual, a screenshot of a "Product description" for the "Genesis LiveDrive," outlines its purported benefits in the robotics industry (Compl. ¶18).
IV. Analysis of Infringement Allegations
The complaint alleges that the Genesis Defendants "have launched and are making, using, selling or offering to sell one or more products that infringe upon the patent rights owned by Douglas Machine" (Compl. ¶19, 37). However, it does not provide a claim chart or detailed infringement theory mapping specific product features to claim elements. The following table summarizes the general allegation against a representative independent claim.
’612 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a two dimensional structure having at least a portion pre-stressed in compression... to form a wave shape having waves along the first direction; | The complaint alleges infringement by the Genesis LiveDrive actuator but does not specify which component constitutes the "two dimensional structure" or how it is pre-stressed to form a "wave shape." | ¶18, ¶19, ¶37 | col. 1:19-24 |
| an output arranged in contact with the waves of the wave shape, the output and the two-dimensional structure movably arranged in relation to one another; and | The complaint does not detail the specific "output" component or describe its physical contact and movable arrangement with the alleged "wave shape." | ¶18, ¶19, ¶37 | col. 1:22-25 |
| a wave propagator arranged to propagate the waves along the first direction to move the output relative to the two dimensional structure. | The complaint does not identify the specific mechanism in the Genesis LiveDrive that functions as the "wave propagator" or explain how it propagates waves to move the output. | ¶18, ¶19, ¶37 | col. 1:25-28 |
Identified Points of Contention
- Evidentiary Questions: The primary question is what evidence will be presented to show that the Genesis LiveDrive, a "direct-drive actuator," operates using the specific mechanism of a "pre-stressed" structure with a "propagating wave" as claimed in the patent. The complaint's allegations are conclusory and lack technical detail.
- Scope Questions: A central dispute may revolve around whether the mechanical principles of the accused "LiveDrive" fall within the scope of the patent's claims. For example, does the accused product's mechanism for generating motion meet the specific limitations of a "wave propagator" acting on a "wave shape" formed by pre-stressed compression?
V. Key Claim Terms for Construction
The complaint does not provide sufficient detail for a full analysis of potential claim construction disputes. However, based on the technology, the following terms may be central.
The Term: "wave propagator"
Context and Importance: This term defines the core mechanism that drives the invention. Its construction will be critical to determining infringement, as Plaintiff must prove the accused product uses a structure that meets this definition. Practitioners may focus on this term because the patent discloses specific means like "piezo actuators or electromagnets" ('612 Patent, col. 1:62-63), and the scope could be disputed if the accused product uses a different or more conventional motor principle.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification describes the term functionally as being "arranged to propagate the waves along the first direction to move the output" ('612 Patent, col. 1:25-28), which could support an interpretation covering any mechanism that performs this function.
- Evidence for a Narrower Interpretation: The specification provides specific examples, such as "electromagnets pulling directly on a soft metallic material attached to the disk," "piezo ceramic material," and "hydraulic pressure" ('612 Patent, col. 6:40-53). A defendant may argue the term should be limited to these disclosed embodiments or their equivalents.
The Term: "pre-stressed in compression"
Context and Importance: This limitation describes the required initial state of the "two dimensional structure" that creates the "wave shape." Proving the accused product contains a component that is "pre-stressed in compression" for this purpose will be a key element of Plaintiff's infringement case.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent summary states the structure has "at least a portion pre-stressed in compression" ('612 Patent, col. 1:20-21), suggesting the entire structure need not be stressed.
- Evidence for a Narrower Interpretation: The detailed description links this stress to specific manufacturing methods, such as "radially tensioned radial spokes or blades" or "thermally shrinking the ID of the disk" ('612 Patent, col. 10:22-27). A party could argue the term is tied to these specific physical processes for inducing the compressive stress.
VI. Other Allegations
Willful Infringement
- The complaint alleges that the "Genesis Defendants are aware of Douglas Machine's rights to the '612 Patent and have been aware of Douglas Machine's rights to the '612 Patent at all relevant times, making the infringement thereof willful" (Compl. ¶38). This allegation appears to be based on the parties' prior business relationship under the Development Consulting Agreement.
VII. Analyst’s Conclusion: Key Questions for the Case
- Ownership: The threshold issue is not infringement but ownership. Before any technical analysis, the court must resolve the breach of contract and declaratory judgment claims to determine if Douglas Machine is the rightful owner of the ’612 Patent, as alleged under the Development Consulting Agreement. The outcome of this contractual dispute is a prerequisite to the patent infringement claim.
- Definitional Scope: Assuming Plaintiff establishes ownership, a central issue will be one of claim scope: can the term "wave propagator," which is described in the patent using unconventional means like piezo strips and electromagnets, be construed to read on the likely more conventional direct-drive motor technology in the accused Genesis LiveDrive?
- Evidentiary Sufficiency: A key question will be one of proof: given the complaint's lack of specific technical allegations, what evidence will Plaintiff produce to demonstrate that the accused actuator's internal mechanics actually perform the functions of a "pre-stressed" structure and a "propagating wave" as recited in the patent claims, rather than operating on a different physical principle?
