Washington v. Caterpillar: Power Generation Patent Suit Dismissed Without Prejudice
Inventor Jerry D Washington Jr filed suit against heavy-equipment giant Caterpillar Inc in the Western District of Texas, asserting US7108095B1 covering a system and method for generating power. The case was dismissed without prejudice after just 277 days, following a magistrate judge’s recommendation to grant Caterpillar’s motion to dismiss for failure to state a claim.
Power Generation Patent Claim Falls at Pleading Stage Against Caterpillar
On June 7, 2024, Jerry D Washington Jr, a pro se inventor-plaintiff, filed a patent infringement action against Caterpillar Inc in the U.S. District Court for the Western District of Texas (Case No. 6:24-cv-00310). The suit asserted US7108095B1, a patent covering a system and method for generating power, against one of the world’s largest manufacturers of construction and power-generation equipment. The case was assigned to Magistrate Judge Derek T. Gilliland.
Caterpillar moved to dismiss under Federal Rule of Civil Procedure 12(b)(6) for failure to state a claim upon which relief can be granted. On March 3, 2025, Judge Gilliland issued a Report and Recommendation concluding the motion should be granted. The court formally closed the case on March 11, 2025, with the dismissal entered without prejudice — meaning Washington retains the procedural right to refile an amended complaint that adequately pleads infringement under Iqbal/Twombly standards.
At 277 days from filing to closure, the case resolved well before claim construction or discovery, suggesting the complaint was found to lack sufficient factual specificity on how Caterpillar’s products practice the asserted patent claims. The public record does not disclose whether Washington intends to refile, amend, or seek review. What remains unknown is whether any licensing discussions occurred in parallel, and whether the underlying patent poses a credible ongoing risk to Caterpillar or the broader power-generation equipment sector.

Dismissed without prejudice: what the ruling means for both parties
Rule 12(b)(6): dismissal for failure to state a claim
A Rule 12(b)(6) motion tests whether a complaint’s factual allegations are sufficient to plausibly support a claim for relief. Courts apply the Iqbal/Twombly standard — bare conclusory assertions of infringement are insufficient. Here, the magistrate recommended dismissal, suggesting the complaint lacked the claim-by-claim factual mapping courts now require in patent cases filed in the Western District of Texas.
Pleading deficiencyWithout prejudice: the door remains open to refile
A dismissal without prejudice does not adjudicate the merits of the patent or infringement allegations. Washington retains the right to file an amended or new complaint with more detailed factual support. However, refiling requires addressing the pleading deficiencies identified by the court — typically a detailed claim chart mapping patent claims to accused product features. The patent’s validity and Caterpillar’s potential exposure remain unadjudicated.
No merits rulingCaterpillar avoids merits ruling — but risk is not fully extinguished
Caterpillar secured dismissal at the pleading stage through McGuireWoods LLP without reaching claim construction, discovery, or a validity determination. This is a cost-efficient result. However, because the dismissal is without prejudice, Caterpillar remains exposed to a refiled, better-pleaded action. The patent US7108095B1 remains in force, and the underlying infringement question has not been adjudicated by any court.
Exposure not fully resolvedPower-generation IP risk: early dismissal limits precedent value
Because the case was dismissed on procedural grounds before any substantive patent analysis, no claim construction, validity ruling, or infringement determination entered the record. This limits the precedential value for the power-generation equipment sector. Competitors and product teams working in the system and method for generating power space should nonetheless monitor US7108095B1 for potential refiling activity or assertion against other defendants.

Official order — verbatim text
The magistrate’s Report and Recommendation granting Caterpillar’s 12(b)(6) motion signals that the complaint failed to allege facts sufficient to plausibly establish infringement of US7108095B1 under controlling pleading standards. Critically, this is a procedural ruling — the court made no determination on whether Caterpillar’s products actually infringe the patent or whether the patent is valid. The without-prejudice designation preserves Washington’s ability to refile with a complaint that includes the factual specificity — typically element-by-element claim mapping against identified accused products — that W.D. Texas courts now consistently require.
US7108095B1 — System and Method for Generating Power
US7108095B1 is a U.S. utility patent covering a system and method for generating power, filed under application number US10/293506. As a granted B1 patent, it issued without a pre-grant publication, suggesting it proceeded through examination without significant public opposition. The patent sits within the power generation and energy conversion domain — a sector directly relevant to Caterpillar’s industrial and commercial generator product lines, diesel-electric systems, and large-scale energy infrastructure offerings.
For a company of Caterpillar’s scale — a dominant global supplier of diesel and gas generators, turbines, and integrated power systems — a granted patent covering power generation methods carries meaningful assertion risk. Even where an initial complaint is dismissed on pleading grounds, the underlying patent remains a live asset. Competitors and supply chain participants in the power-generation equipment space should evaluate whether their products, systems, or processes could read on the claims of US7108095B1, particularly given the patent’s potential breadth as a method claim.
Should your team run an FTO against US7108095B1?
Any company designing, manufacturing, or commercialising power generation systems or equipment — including generator sets, turbine controllers, diesel-electric hybrid systems, or distributed energy platforms — should consider whether US7108095B1 poses freedom-to-operate risk. The fact that this case was dismissed on procedural grounds does not mean the patent is invalid or that its claims are narrow. The patent remains enforceable and could be asserted again, potentially by a better-resourced plaintiff or after assignment.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to rapidly map product features against US7108095B1’s claim language, identify prior art that could support a validity challenge, and monitor the patent’s assignment and litigation history for future assertion signals. Running an FTO now — before any refiling — is significantly less costly than responding to a well-pleaded infringement complaint at a later stage.

What this case signals for the power-generation IP landscape
A pleading-stage dismissal in W.D. Texas underscores how procedural rigour can neutralise patent claims before they reach substantive review.
W.D. Texas enforces Iqbal/Twombly strictly for patent complaints
The Western District of Texas — once the most plaintiff-friendly patent venue — continues to apply rigorous pleading standards post-TC Heartland. Complaints lacking claim-by-claim infringement mapping are increasingly vulnerable to Rule 12(b)(6) dismissal before discovery begins. Defendants in this district should file promptly and specifically.
Without-prejudice dismissal leaves US7108095B1 live and assertable
The patent covering a power generation system and method was never ruled invalid or non-infringed. Any company manufacturing or selling products that could read on US7108095B1’s claims should treat this case as unresolved risk, not a cleared threat. A better-pleaded refiling could survive the next motion to dismiss.
Jr v Caterpillar — key questions answered
Jerry D Washington Jr filed a patent infringement suit against Caterpillar Inc in the Western District of Texas, asserting US7108095B1. Caterpillar moved to dismiss under Rule 12(b)(6) for failure to state a claim. Magistrate Judge Gilliland recommended granting the motion, and the case was dismissed without prejudice on March 11, 2025, after 277 days.
A dismissal without prejudice means the court made no ruling on the merits — neither the patent’s validity nor Caterpillar’s infringement was adjudicated. Washington retains the right to refile a new or amended complaint that adequately pleads infringement with sufficient factual specificity. The patent US7108095B1 remains in force and assertable.
US7108095B1 is a U.S. utility patent filed under application number US10/293506, covering a system and method for generating power. It falls within the power generation and energy conversion domain. Caterpillar manufactures industrial generators, gas turbines, and diesel-electric systems — product lines potentially within the scope of the patent’s claims.
The court recommended dismissal under Rule 12(b)(6), consistent with the Iqbal/Twombly pleading standard, which requires patent complaints to allege facts plausibly establishing infringement — typically requiring claim-by-claim mapping to accused products. The public record suggests the complaint lacked this specificity. The dismissal was without prejudice, allowing a corrected complaint to be filed.
No. Because the dismissal is without prejudice and on procedural — not merits — grounds, Caterpillar’s exposure to US7108095B1 is not extinguished. The patent remains valid and enforceable. Washington or a future assignee could refile a better-pleaded complaint. Companies in the power-generation equipment sector should monitor this patent for further assertion activity.
