Somero v. Twintec USA: Concrete Screed Infringement Suit Dismissed With Prejudice
Somero Enterprises alleged that Twintec USA, Topp & Screed SA, and Industrial Floor Consulting infringed US8038366B2 — a patent covering laser-guided concrete screeding technology — through the TS6100e machine. The Western District of North Carolina dismissed the action with prejudice after 572 days, ending Somero’s claims permanently at the district level.
Somero’s concrete screed patent suit ends at the pleadings stage
On 26 April 2023, Somero Enterprises, Inc. filed suit in the Western District of North Carolina against three defendants — Twintec USA, Inc., Topp & Screed SA (a Swiss entity), and Industrial Floor Consulting, Inc. — asserting infringement of US8038366B2, which covers laser-guided concrete screeding apparatus and methods. The accused product was the TS6100e machine sold or promoted by the defendant group in the United States market.
The case closed on 18 November 2024 when the court granted defendants’ Rule 56 Motion to Dismiss, entering dismissal with prejudice. A dismissal with prejudice is a final adjudication on the merits: Somero cannot re-file the same claims against these defendants in any federal court. The defendants — represented by Morgan Lewis & Bockius LLP and Shumaker, Loop & Kendrick — successfully ended the litigation without a full trial, a significant procedural win.
At 572 days, the case ran longer than a typical early-dismissal but shorter than full patent trial timelines, suggesting substantive motion practice occurred before termination. What drove the dismissal — whether claim construction, standing issues, or merits deficiencies — is not fully specified in the public termination record, leaving the precise legal basis uncertain beyond the docket notation of a granted motion to dismiss with prejudice.

Dismissed with prejudice: what the court’s ruling means for both sides
Dismissal with prejudice is a final, binding termination
The court granted defendants’ Motion to Dismiss and entered dismissal with prejudice under the federal rules. This is not a procedural pause or voluntary exit — it is a final adjudication that extinguishes Somero’s right to re-file these specific infringement claims against these defendants in any U.S. federal court. The ruling has res judicata effect, meaning the same cause of action cannot be relitigated.
Res judicata appliesSomero loses enforcement rights against this defendant group
Somero Enterprises cannot reassert US8038366B2 against Twintec USA, Topp & Screed SA, or Industrial Floor Consulting for the conduct alleged in this action. The patent itself remains in force and Somero retains the right to enforce it against other parties, but the dismissal with prejudice forecloses any second attempt against the same defendants on the same claims. This represents a complete loss of the enforcement action as filed.
Patent survives; this claim does notDefendants obtain permanent protection from this specific suit
All three defendants — Twintec USA, Topp & Screed SA, and Industrial Floor Consulting — exit litigation with the strongest possible termination short of a judgment of non-infringement or invalidity. The TS6100e machine is no longer subject to these particular claims. However, the patent’s validity was not adjudicated, meaning US8038366B2 could still be enforced against the defendants’ future products if new conduct arises outside the scope of this action.
TS6100e claims permanently closedSector takeaway: patent survives, but enforcement tested
For the concrete screeding and floor construction equipment sector, this outcome suggests that asserting broad equipment patents against international defendant groups in U.S. district courts carries procedural risk. Somero’s US8038366B2 remains an active asset, but competitors and design engineers working on laser-guided screed technology should monitor whether Somero pursues further enforcement or whether the dismissal signals a reassessment of litigation strategy around this patent.

Official order — verbatim text
The order granting the Motion to Dismiss with prejudice indicates the court found a threshold deficiency sufficient to terminate the entire action permanently. In patent cases, dismissal with prejudice at the motion stage typically reflects a failure of pleading sufficiency, claim construction that eliminates viable infringement allegations, or a standing defect — though the public record does not specify the precise ground. The with-prejudice designation is significant: it bars Somero from re-litigating these claims, giving the defendants a final win without the cost and uncertainty of a full Markman hearing or trial.
US8038366B2 — Laser-guided concrete screed apparatus and method
US8038366B2, filed under application number US12/951532, protects laser-guided concrete screeding apparatus and associated methods used in the construction of flat, level concrete floors. The technology is commercially significant in large-scale industrial and warehouse floor construction, where surface flatness tolerances are critical for racking systems, automated guided vehicles, and heavy equipment operations. Somero Enterprises has historically positioned this patent family as a core competitive moat in the powered screed market.
The assertion against the TS6100e machine signals that Somero views this patent as capable of reaching competing laser-guided screed products from European manufacturers entering the U.S. market. For competitors in the floor construction equipment sector, US8038366B2 represents a potential enforcement risk for any machine that incorporates laser-guided levelling with a screed head mechanism. The patent’s application date context suggests it predates several newer entrants, giving it temporal breadth across a generation of commercial screed technology.
Should you run an FTO check against US8038366B2?
Any manufacturer, importer, or U.S. distributor of laser-guided concrete screed machines — particularly those incorporating automated grade-sensing and screed-head positioning — should treat US8038366B2 as a live risk asset. The dismissal in this case did not invalidate the patent. Somero retains enforcement rights, and the TS6100e litigation demonstrates the company’s willingness to pursue both foreign manufacturers and their U.S. distribution partners simultaneously. R&D teams developing next-generation screed platforms should map their feature sets against the claim language before U.S. market entry.

What this case signals for the concrete screed equipment IP landscape
A dismissed-with-prejudice outcome in a multi-defendant equipment patent suit carries implications well beyond this docket.
US8038366B2 remains live — monitor future enforcement actions
Despite the dismissal, US8038366B2 has not been declared invalid or unenforceable. Somero retains full rights to assert it against new parties or for new acts of infringement. Competitors in the laser-guided concrete screed market should track any new filings or ITC actions involving this patent.
Multi-defendant structures add complexity — choose venues carefully
Suing a Swiss manufacturer (Topp & Screed SA), a U.S. distributor (Twintec USA), and a consulting firm simultaneously in one district creates jurisdictional and joinder complexity. The dismissal with prejudice suggests those structural challenges may have contributed to the outcome, consistent with common pitfalls in multi-party patent enforcement.
Somero v Twintec — key questions answered
The Western District of North Carolina dismissed Somero’s patent infringement action with prejudice on 18 November 2024. Somero had alleged that Twintec USA, Topp & Screed SA, and Industrial Floor Consulting infringed US8038366B2 through the TS6100e concrete screed machine. The court granted defendants’ Motion to Dismiss, ending the case permanently after 572 days.
Yes. The dismissal with prejudice resolved the case on procedural or pleading grounds — no court adjudicated the validity or invalidity of US8038366B2. The patent remains in force, and Somero retains the right to assert it against other parties or for new alleged infringement. Competitors should not assume the patent is cleared based on this outcome.
Dismissal with prejudice means Somero cannot re-file the same infringement claims against Twintec USA, Topp & Screed SA, or Industrial Floor Consulting in any U.S. federal court. The ruling has res judicata effect. However, the TS6100e’s non-infringement or the patent’s invalidity were not formally established — only these specific claims by Somero are permanently barred.
US8038366B2 covers laser-guided concrete screeding apparatus and methods used to create flat, level concrete floors in industrial and commercial settings. It is commercially significant for warehouse, distribution centre, and manufacturing floor construction where surface flatness is critical for automated systems and heavy equipment. Somero Enterprises holds a portfolio of screed technology patents and has historically used them to defend market position against international competitors.
Not on the same claims arising from the same conduct. The dismissal with prejudice creates a res judicata bar preventing Somero from reasserting the claims already litigated in Case No. 3:23-cv-00245. If genuinely new acts of infringement occur after the case closure date, or if different claims or patents are involved, Somero could theoretically file a new action — but the specific infringement allegations from this suit are permanently extinguished.
