II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 5,513,829, "Cradle Support Holder," issued May 7, 1996
The Invention Explained
- Problem Addressed: The patent describes the instability and difficulty of supporting automotive components, such as transverse transmissions, on conventional telescoping jacks. The narrow support area of standard jack heads can cause components to topple or sway during removal or installation ('829 Patent, col. 1:12-28).
- The Patented Solution: The invention is an interface device between a jack and a component, featuring a central "box-like support" with extendable arms that pivot from its corners. These arms terminate in support pads, creating a wide and stable base that can be adjusted to fit the component, distributing the load evenly and preventing instability ('829 Patent, col. 1:47-62; Fig. 1).
- Technical Importance: The invention aims to provide a stable, reliable, and versatile support device that improves safety and efficiency when handling heavy automotive components ('829 Patent, col. 2:7-11).
Key Claims at a Glance
- The complaint asserts the patent generally without specifying claims (Compl. ¶16). Independent claim 1 is the sole independent claim.
- Independent Claim 1 Elements:
- A "box-like support" with a central opening
- A continuous sidewall on the support's marginal region
- The "box-like member" having at least three corners
- At least three "extendable arms"
- A "pivot device" connecting one end of each arm to a corner of the support
- A "support pad" detachably carried on the other end of the arm
- The "extendable arm" being "articulated" for selective positioning of the pads
- The patent contains three dependent claims. The complaint does not explicitly reserve the right to assert them.
U.S. Patent No. 5,547,206, "Vehicle Dolly Apparatus," issued August 20, 1996
The Invention Explained
- Problem Addressed: When a vehicle's "four-point cradle" (engine/transaxle subframe) is removed for repairs, the vehicle is immobilized, occupying a repair bay for extended periods. This creates significant inefficiency. Prior art dollies intended to solve this were reportedly cumbersome, prone to collapse, and difficult to use ('206 Patent, col. 1:14-54).
- The Patented Solution: The patent discloses a vehicle dolly that temporarily replaces the subframe. It is built around a "telescopic forward stabilizer bar" with swivel casters. Two adjustable rear struts connect to this bar via U-joints, allowing them to pivot horizontally and vertically. This creates a highly adaptable support structure that can be configured for different vehicles by a single operator ('206 Patent, Abstract; col. 3:9-14).
- Technical Importance: The invention provides a lightweight, durable, and highly versatile dolly that allows a vehicle without its subframe to be safely moved, freeing up valuable repair bay space ('206 Patent, col. 6:1-4).
Key Claims at a Glance
- The complaint asserts the patent generally without specifying claims (Compl. ¶16). Claims 1, 13, 18, and 20 are independent.
- Independent Claim 1 Elements:
- A "forward stabilizer bar" with telescopically mounted horizontal tubes
- First and second "tube point plate means" pivotally attached to the tubes for vehicle connection
- "Caster means" for mobility
- First and second "rear struts"
- "Means for mounting" the struts to the stabilizer bar to provide pivotal movement
- "Means rotatably positionable" along the struts for connection to a vehicle frame
- The patent contains sixteen dependent claims. The complaint does not explicitly reserve the right to assert them.
Multi-Patent Capsule: U.S. Patent No. 5,599,031
- Patent Identification: U.S. Patent No. 5,599,031, "Work Dolly Having Adjustable Height, Width and Length," issued February 4, 1997.
- Technology Synopsis: The patent addresses the problem that conventional dollies are not adjustable to fit different loads, leading to uneven support ('031 Patent, col. 1:15-26). The invention provides a dolly with a rectangular frame composed of telescoping side and end members, allowing for adjustment of both width and length. It also includes height-adjustable legs at each corner to accommodate various load configurations ('031 Patent, col. 2:30-55).
- Asserted Claims: Not specified in the complaint; Claim 1 is the sole claim ('031 Patent, col. 3:33).
- Accused Features: The complaint makes a general allegation of infringement by "products employing the patented inventions" (Compl. ¶16).
Multi-Patent Capsule: Design Patents
The complaint also asserts four design patents, each claiming the ornamental design for a specific article of automotive equipment. The infringement allegations are general and do not identify specific accused products (Compl. ¶16).

No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
The complaint does not provide specific factual allegations or claim charts mapping accused product features to the elements of the asserted patent claims. The analysis below is based on the structure of the independent claims and the general infringement allegations in the complaint.
’829 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a box-like support having a central opening defined by a surrounding plate edge marginal region | The complaint alleges infringement but does not describe the specific features of the accused products that purportedly practice this element. | ¶16 | col. 2:58-62 |
| a continuous sidewall carried on said plate edge marginal region | The complaint alleges infringement but does not describe the specific features of the accused products that purportedly practice this element. | ¶16 | col. 2:62-64 |
| at least three extendable arms, each arm having opposite ends | The complaint alleges infringement but does not describe the specific features of the accused products that purportedly practice this element. | ¶16 | col. 2:65-68 |
| a pivot device connecting one end of said extendable arm to a selected corner of said box-like support | The complaint alleges infringement but does not describe the specific features of the accused products that purportedly practice this element. | ¶16 | col. 2:65-66 |
| a support pad detachably carried on the other end of said arm | The complaint alleges infringement but does not describe the specific features of the accused products that purportedly practice this element. | ¶16 | col. 3:1-6 |
| said extendable arm being articulated with respect to said box-like support for selective positioning and location of said pads | The complaint alleges infringement but does not describe the specific features of the accused products that purportedly practice this element. | ¶16 | col. 4:49-52 |
’206 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a forward stabilizer bar including first and second horizontal tubes telescopically mounted and movable with respect to one another | The complaint alleges infringement but does not describe the specific features of the accused products that purportedly practice this element. | ¶16 | col. 7:1-3 |
| first and second tube point plate means pivotally attached respectively to said first and second horizontal tubes for connection to a vehicle | The complaint alleges infringement but does not describe the specific features of the accused products that purportedly practice this element. | ¶16 | col. 7:6-8 |
- Identified Points of Contention:
- Evidentiary Question: A primary issue will be whether the Plaintiff can produce evidence demonstrating that Transtar's unspecified products contain structures that meet every limitation of the asserted claims. The complaint's lack of specificity places the entire evidentiary burden on facts to be developed in discovery.
- Scope Questions: Assuming evidence of an accused product is presented, disputes may arise over the scope of key terms. For the '829 Patent, a question may be whether an accused device's central frame qualifies as a "box-like support." For the '206 Patent, a question may be whether the accused product's adjustment mechanism for connecting to a vehicle frame constitutes a "means rotatably positionable along said rear struts."
V. Key Claim Terms for Construction
The complaint does not create an explicit dispute over any claim term. However, the following terms may become central to the infringement analysis.
Term: "box-like support" ('829 Patent, Claim 1)
- Context and Importance: This term defines the central structural element of the invention. Its construction will be critical to determining if an accused product's frame, which may have a different shape or configuration, falls within the scope of the claim.
- Intrinsic Evidence for a Broader Interpretation: The specification describes the element's function as interfacing with a jack and supporting the extendable arms, potentially allowing for shapes other than a literal box that still perform this function (e.g., '829 Patent, col. 1:47-55).
- Intrinsic Evidence for a Narrower Interpretation: The figures consistently depict a four-sided, rectangular structure (e.g., '829 Patent, Fig. 1, 3). A party could argue the term should be limited to the embodiments shown, which are distinctly "box-like."
Term: "means for mounting" ('206 Patent, Claim 1)
- Context and Importance: This is a means-plus-function limitation under 35 U.S.C. § 112, ¶ 6 (pre-AIA). Its scope is limited to the corresponding structure described in the specification and its equivalents. The function is "mounting each of said first and second rear struts to said forward stabilizer bar so as to provide pivotal movement."
- Intrinsic Evidence for Interpretation: The specification discloses the corresponding structure as a U-joint assembly, comprising a "drop tube strut holder," a "round U-joint nut," a "U-joint body," and bolts ('206 Patent, col. 4:5-14; Fig. 4). The infringement analysis for this element will require determining whether the accused products use this specific U-joint structure or a structural equivalent.
VI. Other Allegations
- Indirect Infringement: The complaint alleges that Transtar is "actively inducing the sale of products employing the patented inventions" (Compl. ¶16). It does not, however, plead specific facts to support the knowledge and intent elements of inducement, such as referencing user manuals or marketing materials that instruct on an infringing use.
- Willful Infringement: The complaint alleges that Transtar "has acted and continues to act with full and actual knowledge of the patent rights of Hodges and Transtar's acts of infringement have been willful and deliberate" (Compl. ¶17). No specific facts supporting pre-suit knowledge, such as a prior notice letter or copying, are alleged. The prayer for relief requests treble damages for willful infringement (Compl. at p. 4).
VII. Analyst’s Conclusion: Key Questions for the Case
- Evidentiary Sufficiency: The central threshold question is an evidentiary one: what evidence will the Plaintiff introduce to connect the general allegations in the complaint to specific features of the Defendant's products, and will that evidence be sufficient to show that those products practice every element of the asserted claims?
- Claim Construction and Scope: A key legal question will be one of definitional scope. For the utility patents, can terms like "box-like support" ('829 patent) be construed broadly enough to read on the Defendant's potentially different frame designs? For the design patents, the question will be whether an ordinary observer would find the Defendant's designs substantially the same as the patented designs.
- Willfulness and Knowledge: A critical factual question will be whether the Plaintiff can substantiate its claim of "full and actual knowledge" with concrete evidence. Without proof of pre-suit notice or deliberate copying, the claim for willful infringement may face significant challenges.
