Westlake Royal v. InnovaTools: Bending Brake Patent Settled After 791 Days
Westlake Royal Building Products filed suit against InnovaTools in April 2023, asserting US7549311B2 covering sheet metal bending brake technology. After 791 days of litigation, the parties reached a settlement on April 30, 2025, resulting in dismissal with prejudice — with each side bearing its own legal costs.
Building Products Patent Dispute Ends in Confidential Settlement
Westlake Royal Building Products, Inc. — a major manufacturer in the residential and commercial building products sector — initiated this infringement action against InnovaTools, Inc. on April 6, 2023, in the U.S. District Court for the Eastern District of Michigan. The suit centred on US7549311B2, a patent directed at sheet metal bending brake technology used in construction and installation applications. Westlake Royal alleged that InnovaTools infringed that patent through competing products or tools in the same space.
The case concluded through a negotiated settlement agreement executed on April 30, 2025, followed by a joint stipulation filed June 3, 2025, and formal closure on June 5, 2025. All claims and counterclaims — including InnovaTools’ counterclaims against Westlake Royal — were dismissed with prejudice under Rule 41(a). Neither party was awarded fees or costs. Notably, the settlement agreement designated the U.S. District Court for the Eastern District of Texas (Sherman Division) as the exclusive forum for any future disputes arising from the agreement or the underlying patent action.
At 791 days, the litigation ran well beyond a typical early-stage dismissal, suggesting that meaningful claim construction, discovery, or licensing negotiations took place before the parties converged on terms. The mutual dismissal with prejudice means neither side can relitigate these specific claims. The forum selection clause — pointing to the Eastern District of Texas — may reflect where future commercial or licensing disputes between these parties are expected to surface. The financial terms of the settlement remain confidential and cannot be determined from the public record.

Settled and dismissed with prejudice: what the terms mean for both parties
Rule 41(a) dismissal with prejudice closes all claims permanently
A dismissal with prejudice under Rule 41(a) is a final adjudication on the merits. Neither Westlake Royal nor InnovaTools can re-file the same infringement claims or counterclaims in any court. This is the most conclusive form of voluntary dismissal available under the Federal Rules of Civil Procedure, and here it was entered by joint stipulation, confirming both parties’ consent to the finality of the resolution.
Permanent bar on re-filingWestlake Royal secures confidential terms but foregoes public vindication
By settling, Westlake Royal avoided the risk of an adverse ruling on validity or infringement. The dismissal with prejudice suggests the plaintiff achieved some negotiated value — potentially a licence, product design change, or compensation — though none of these terms are disclosed in the public record. The patent US7549311B2 remains in force and may still be asserted against third parties not party to this settlement.
US7549311B2 remains enforceableInnovaTools avoids an infringement finding but is barred from counterclaims
InnovaTools’ counterclaims — which may have challenged the validity or enforceability of US7549311B2 — were also dismissed with prejudice, meaning InnovaTools cannot later pursue an invalidity or unenforceability argument in the same forum against Westlake Royal. The mutual cost-bearing provision suggests neither party held overwhelmingly dominant leverage at the time of settlement.
Counterclaims permanently dismissedTexas forum clause signals where future IP disputes between these parties will land
The settlement’s designation of the Eastern District of Texas (Sherman Division) as the exclusive jurisdiction for future disputes is commercially significant. This forum is known for its patent-friendly procedures and experienced patent dockets. Any licensing breach or future infringement allegation tied to this settlement or patent will bypass Michigan courts entirely, which may affect litigation strategy for both parties and their legal teams going forward.

Official order — verbatim text
The stipulated dismissal language confirms a full bilateral resolution: all claims by Westlake Royal and all counterclaims by InnovaTools are extinguished with prejudice. The reference to Federal Rule of Civil Procedure 41(a) signals a court-approved consent mechanism rather than a unilateral withdrawal. The explicit cost-neutrality clause and the forward-looking Texas forum selection provision are commercially negotiated terms that go beyond a standard dismissal, suggesting the underlying settlement agreement contains substantive licensing or commercial conditions not visible in the public filing.
US7549311B2 — Sheet Metal Bending Brake Apparatus and Method
US7549311B2 protects a sheet metal bending brake — a mechanical tool used to form precise bends and folds in sheet metal, commonly applied in roofing, cladding, flashing, and exterior finishing trades. The underlying application (US12/044839) entered prosecution reflecting innovations in brake design, clamping mechanisms, or bending accuracy. Sheet metal bending brakes are foundational tools in the building envelope segment, bridging construction manufacturing and on-site installation practice.
For Westlake Royal — whose product lines span exterior cladding, trim, and building accessories — a patent covering bending brake technology protects a core downstream installation tool aligned with its materials portfolio. Competitor tool manufacturers, distributors of sheet metal working equipment, and OEM suppliers to the residential and commercial construction sector should treat US7549311B2 as an active enforcement asset. The settlement without invalidity finding means the patent’s claims are untested publicly and carry full presumption of validity.
Should your team run an FTO analysis against US7549311B2?
Any company designing, manufacturing, distributing, or commercialising sheet metal bending brake tools for the construction and building products market should assess its exposure to US7549311B2. This case demonstrates that Westlake Royal is willing to enforce the patent through multi-year litigation. The patent’s claims remain valid and enforceable following settlement — no court has invalidated any claim. R&D teams developing competing bending brake products or iterating on clamping and forming mechanisms should prioritise FTO clearance before market entry.
PatSnap Eureka’s FTO Search Agent enables your team to map the claim scope of US7549311B2 against your product architecture, identify design-around pathways, and benchmark against the prior art landscape in sheet metal forming and brake tool technology.

What this case signals for the building products IP landscape
A 791-day lifecycle ending in mutual dismissal with prejudice reveals how bending brake patent disputes typically resolve — and where leverage shifts.
Dismissal with prejudice signals substantive settlement value, not a walkaway
When both parties agree to dismiss all claims and counterclaims with prejudice after nearly two years, it typically signals a negotiated exchange of value rather than a simple abandonment. Building products companies and tool manufacturers considering similar IP positions should treat this pattern as evidence that enforcement of mechanical tooling patents can yield commercial outcomes without trial.
US7549311B2 remains active and enforceable against the broader market
Settlement with one competitor does not exhaust Westlake Royal’s rights under US7549311B2. Competitors and OEM tool suppliers operating in the sheet metal bending brake segment should assess their exposure to this patent independently. The absence of any invalidity ruling leaves the patent’s claims fully intact against third parties.
Westlake v InnovaTools — key questions answered
The case was dismissed with prejudice on June 5, 2025, following a settlement agreement reached on April 30, 2025. All claims and counterclaims were extinguished under Rule 41(a), with each party bearing its own attorneys’ fees and costs. The financial terms of the settlement are not disclosed in the public record.
Westlake Royal asserted US7549311B2, a patent covering sheet metal bending brake apparatus and methods. The underlying application number is US12/044839. The patent relates to mechanical bending brake tools used in sheet metal forming, commonly applied in roofing, cladding, and exterior construction finishing.
No. A dismissal with prejudice by settlement does not constitute a merits adjudication on patent validity. US7549311B2 retains its full presumption of validity and remains enforceable against any third party not party to this settlement. No court issued any claim construction ruling or invalidity finding in this case.
The parties contractually selected the U.S. District Court for the Eastern District of Texas (Sherman Division) as the exclusive jurisdiction for any future disputes arising from the settlement or the underlying patent action. This is a negotiated forum selection clause, not a court order. The Eastern District of Texas is known for its established patent litigation docket and procedures, which may have influenced the choice.
InnovaTools’ counterclaims — which may have included invalidity claims — were dismissed with prejudice, barring InnovaTools from re-asserting those specific claims against Westlake Royal in future litigation. However, InnovaTools or any other party may still file an inter partes review (IPR) petition before the USPTO Patent Trial and Appeal Board, which operates independently of district court proceedings and is not precluded by this settlement.
