ESP Inc. v. Century Label & CMC Group: AR/VR Patent Suit Voluntarily Dismissed
Electronic Scripting Products, Inc. asserted two augmented and virtual reality patents against Century Label and CMC Group, Inc. in Ohio’s Northern District. The plaintiff voluntarily dismissed both defendants without prejudice after just 84 days — leaving the door open for future enforcement action.
AR/VR Patent Claims Drop Early — But the Risk Isn’t Gone
Electronic Scripting Products, Inc. filed this infringement action on 28 August 2024 in the Ohio Northern District Court before Judge James G. Carr, asserting US7826641B2 and US10191559B2 against Century Label and CMC Group, Inc. Both patents relate to technology for incorporating augmented or virtual reality, a domain where enforcement activity has intensified as AR/VR hardware and software proliferate across industrial and consumer applications.
On 20 November 2024 — just 84 days after filing — plaintiff Electronic Scripting Products notified the Court of voluntary dismissal without prejudice of both defendants pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). No defendants’ counsel had entered an appearance on the public docket, and no substantive motions were adjudicated prior to termination. The without-prejudice designation is critical: it means no merits ruling was issued and the plaintiff is not barred from reasserting these same patents against these same defendants.
The 84-day resolution suggests the parties may have reached a pre-litigation accommodation — whether a licensing arrangement, a design-around agreement, or simply a strategic decision to pause — though the public record is silent on the precise driver. The absence of any defendant representation on the docket and the speed of dismissal are consistent with early, informal resolution. Whether Electronic Scripting Products re-engages these defendants or pivots to others in the AR/VR space remains an open question.

Voluntarily dismissed: what the without-prejudice ruling means for both parties
Rule 41(a)(1)(A)(ii) dismissal — no merits adjudicated
A voluntary dismissal under Fed. R. Civ. P. 41(a)(1)(A)(ii) allows a plaintiff to exit the case before a defendant has answered or moved for summary judgment, provided all parties who have appeared stipulate. This is a procedural exit, not a substantive ruling. The court made no finding on patent validity, infringement, or enforceability — the legal questions raised by the complaint remain entirely open.
No merits ruling issuedDismissal ‘without prejudice’ preserves plaintiff’s right to refile
A dismissal without prejudice means the plaintiff is not barred from bringing the same claims again. Had the dismissal been ‘with prejudice,’ the claims would be extinguished. The public record here states only ‘Voluntary dismissal’ as the basis of termination — the without-prejudice designation appears in the verdict text. Defendants gain no res judicata protection and cannot point to this case as a final adjudication in their favour.
Refile risk remains liveDefendants exit the case — but face no permanent shield
Century Label and CMC Group, Inc. are released from this particular action with no adverse judgment on the record. However, the without-prejudice nature of the dismissal provides no lasting protection. Both defendants should treat this as a temporary pause rather than a final resolution, and consider whether their AR/VR-related products or processes remain exposed to the asserted patents or the broader Electronic Scripting Products portfolio.
No permanent protection grantedEarly exit typical of licensing talks — sector risk persists
Rapid voluntary dismissals without prejudice are frequently consistent with early licensing negotiations or pre-suit settlements that the parties prefer to keep confidential. For companies in the AR/VR and interactive media space, this case signals that US7826641B2 and US10191559B2 are actively being enforced. Competitors incorporating augmented or virtual reality into products or services should assess FTO exposure against the Electronic Scripting Products portfolio now rather than after a new filing.

Official order — verbatim text
The voluntary dismissal notice invokes Rule 41(a)(1)(A)(ii), indicating no defendant had yet answered or filed a summary judgment motion — a procedural posture that allowed plaintiff to exit unilaterally. The explicit ‘without prejudice’ designation is significant: it preserves the entire cause of action for future proceedings. Neither patent validity nor infringement was adjudicated, meaning both US7826641B2 and US10191559B2 retain their presumption of validity and remain fully enforceable assets in the Electronic Scripting Products portfolio.
US7826641B2 & US10191559B2 — Augmented and Virtual Reality Technology
US7826641B2 (application no. US12/584402) and US10191559B2 (application no. US15/914797) both cover technology for incorporating augmented or virtual reality — a domain spanning positional tracking, overlaid digital content, and interactive user interfaces. The later application number on US10191559B2 suggests it post-dates US7826641B2 and may represent a continuation or related development, potentially extending claim coverage across updated implementations. Both patents carry the full statutory presumption of validity as granted US patents.
AR/VR patent portfolios held by specialist IP companies like Electronic Scripting Products represent a material enforcement risk for any downstream product or service that integrates immersive technology. The assertion of these patents against a labelling company and a commercial group suggests the patents’ claims may be drafted broadly enough to reach non-core AR/VR implementers. For hardware manufacturers, software developers, and industrial operators deploying AR/VR features, a freedom-to-operate assessment against this portfolio is a commercially prudent step.
Should your team run an FTO against US7826641B2 and US10191559B2?
Any R&D team, product manager, or in-house counsel at a company integrating augmented or virtual reality features into products, packaging, or workflows should evaluate exposure to these two patents. This case demonstrates that Electronic Scripting Products is actively enforcing its AR/VR portfolio against commercial entities — including those not traditionally regarded as core AR/VR technology companies. The without-prejudice dismissal preserves that enforcement threat entirely.

What this case signals for the AR/VR IP enforcement landscape
A fast, without-prejudice exit rarely signals the end of enforcement — it often signals a reset before the next target.
Without-prejudice dismissal is not a clearance — refile risk is live
Companies in the AR/VR supply chain should not treat this dismissal as a clean bill of health. Electronic Scripting Products retains full rights to reassert US7826641B2 and US10191559B2 against Century Label, CMC Group, or any other party. The 84-day timeline is consistent with licensing discussions, but no public agreement has been disclosed.
Early AR/VR enforcement filings are accelerating — monitor actively
The assertion of AR/VR patents against commercial labelling and group companies suggests plaintiffs are broadening enforcement beyond core technology developers. Any business deploying AR/VR features — even peripherally — should conduct proactive FTO analysis against the Electronic Scripting Products portfolio before product launch or feature integration.
Electronic v Century — key questions answered
The voluntary dismissal without prejudice means Electronic Scripting Products ended this specific action without any merits ruling. Under Rule 41(a)(1)(A)(ii), no findings were made on infringement or patent validity. Critically, the without-prejudice designation means ESP retains the right to refile the same claims against Century Label and CMC Group, Inc. at any future date — no res judicata bar applies.
Electronic Scripting Products asserted two patents: US7826641B2 (application no. US12/584402) and US10191559B2 (application no. US15/914797). Both patents relate to technology for incorporating augmented or virtual reality. Neither patent’s validity nor infringement was adjudicated in this case due to the early voluntary dismissal.
The 84-day resolution suggests early pre-litigation resolution, though the public record does not disclose the specific reason. No defendant counsel appeared on the docket, no substantive motions were filed, and dismissal came before any defendant response. This pattern is consistent with a licensing agreement, a design-around understanding, or a strategic decision to pause enforcement — but none of these can be confirmed from public filings.
No. A Rule 41(a)(1)(A)(ii) dismissal without prejudice provides no permanent protection to Century Label or CMC Group, Inc. Electronic Scripting Products can refile identical claims. The only procedural protection that could arise is the ‘two dismissal rule’ under Rule 41(a)(1)(B): if ESP refiles and voluntarily dismisses a second time, that second dismissal would operate as an adjudication on the merits — effectively with prejudice.
These two Electronic Scripting Products patents cover augmented and virtual reality incorporation technology. Their active enforcement against commercial entities — not only core AR/VR developers — signals a broad claim scope. Companies integrating AR/VR into products, packaging, or industrial processes should conduct freedom-to-operate analysis against both patents and monitor the broader ESP portfolio for continuation applications that could extend claim coverage to adjacent implementations.
