3D Scan Guide LLC v. National Dentex Labs: Dismissed With Prejudice After 764 Days
3D Scan Guide LLC asserted reissued patent USRE047368E — covering a modular template for drilling holes used in dental prosthetics — against National Dentex Labs, LLC in the Southern District of Texas. The court dismissed all claims with prejudice following the defendant’s successful Motion for Reconsideration, a terminal outcome for the plaintiff after over two years of litigation.
Reissued Dental Template Patent Extinguished on Reconsideration
On April 19, 2023, 3D Scan Guide LLC filed suit against National Dentex Labs, LLC in the U.S. District Court for the Southern District of Texas (Case No. 4:23-cv-01458) before Judge Alfred H. Bennett. The plaintiff asserted reissued patent USRE047368E, which covers a modular template system for drilling holes used in dental prosthetic procedures — a technology directly relevant to National Dentex Labs’ dental laboratory operations. The case was prosecuted by Garteiser Honea PLLC on behalf of the plaintiff, with Frost Brown Todd LLP defending.
The case closed on May 22, 2025, when the court granted National Dentex Labs’ Motion for Reconsideration and entered a Final Judgment dismissing all of 3D Scan Guide’s claims with prejudice under Federal Rule of Civil Procedure 58. A dismissal with prejudice is a final adjudication on the merits, meaning the plaintiff is permanently barred from reasserting the same infringement claims against National Dentex Labs based on USRE047368E. The reconsideration mechanism suggests a prior ruling was reversed at the defendant’s urging, a strategically significant procedural victory.
At 764 days, the case exceeded the typical median resolution window for patent cases in the Southern District of Texas, suggesting meaningful substantive litigation occurred before termination. The precise legal basis underlying the reconsideration grant — whether claim construction, standing, eligibility, or another threshold issue — is not fully disclosed in the public docket record. What is clear is that the defendant achieved the most complete available defense outcome: a with-prejudice dismissal that forecloses any refiling of these specific claims in this jurisdiction.

Dismissed with prejudice: what the final judgment means for both parties
Reconsideration granted — case terminated at the defendant’s motion
The court granted National Dentex Labs’ Motion for Reconsideration (Doc. #49) and simultaneously entered Final Judgment under Fed. R. Civ. P. 58. A successful reconsideration motion typically requires the movant to show a clear error of law, newly available evidence, or an intervening change in controlling authority. Granting reconsideration at this stage suggests the court identified a dispositive legal deficiency in the plaintiff’s case that was not resolved in an earlier ruling.
Motion for Reconsideration grantedWith-prejudice dismissal bars any refiling of these claims
A dismissal with prejudice operates as a final judgment on the merits. Unlike a without-prejudice dismissal — which leaves the door open to refile — 3D Scan Guide LLC is permanently precluded from reasserting the same USRE047368E infringement claims against National Dentex Labs in any federal court. The plaintiff retains the patent but has exhausted its litigation avenue against this defendant on these specific claims absent a successful appeal.
Claims extinguished — no refiling permittedNational Dentex Labs secures full dismissal with no liability exposure
National Dentex Labs achieved the strongest possible defense result: all claims dismissed with prejudice and a formal Final Judgment entered in its favor. The company faces no damages liability, no injunction risk, and no obligation to design around USRE047368E with respect to this litigation. The success of the Motion for Reconsideration suggests defendant’s counsel identified a threshold legal vulnerability — likely in validity, standing, or claim scope — that proved decisive.
Full defense victory — zero liabilityDental lab sector: USRE047368E enforcement credibility now in question
The with-prejudice outcome against a major dental laboratory operator signals that USRE047368E may face significant enforceability or validity challenges. Other dental labs and dental CAD/CAM technology suppliers operating in the modular drilling template space should monitor whether 3D Scan Guide pursues additional enforcement campaigns. The reissued patent’s broadened or corrected claims may attract heightened scrutiny in any subsequent assertion. An IPR petition could now be a cost-effective defensive tool for the industry.

Official order — verbatim text
The Final Judgment language is unambiguous: the court granted the defendant’s Motion for Reconsideration and entered a with-prejudice dismissal of all plaintiff’s claims in a single simultaneous order. The procedural posture — reconsideration leading directly to final judgment — suggests the court identified a dispositive defect that had not been adequately resolved in a prior ruling, consistent with a threshold legal bar such as standing, claim validity, or subject-matter eligibility. The with-prejudice designation forecloses any future reassertion of these claims against National Dentex Labs by 3D Scan Guide LLC.
USRE047368E — Modular Dental Drilling Guide Template Technology
USRE047368E is a reissued U.S. patent covering a modular template for drilling holes and a method of making the same — technology applied in dental prosthetic workflows, including implant guide fabrication. As a reissued patent (filing basis US15/615417), it reflects a post-grant correction or claim adjustment by the USPTO, which can broaden, narrow, or clarify original claim scope. The reissue designation is commercially significant: reissued patents may carry broader claims than the original grant but are subject to intervening rights for third parties who began practicing the technology before reissue.
In the dental laboratory sector, modular drilling template technology underpins precision implant placement workflows increasingly integrated into digital dentistry platforms. National Dentex Labs, as a major dental laboratory operator, would be a natural target for enforcement of any broadly scoped template patent. The failed enforcement here — resolved via with-prejudice dismissal — suggests either claim scope limitations, reissue-specific defenses, or standing issues constrained the patent’s litigation viability. Competitors and suppliers in the dental CAD/CAM and implant guide manufacturing space should assess the patent’s current claim scope carefully before designing new workflows.
Should you run an FTO analysis against USRE047368E?
Any company manufacturing, distributing, or integrating modular dental drilling guide templates — including dental laboratories, CAD/CAM software vendors, and implant guide fabricators — should assess freedom to operate against USRE047368E. Although enforcement against National Dentex Labs failed with prejudice, the patent remains in force and 3D Scan Guide LLC may pursue other parties. The reissue history means claim scope may differ materially from the original patent, requiring a reissue-specific analysis rather than reliance on a prior FTO conducted against the original grant.

What this case signals for the dental technology IP landscape
A with-prejudice dismissal on reconsideration raises pointed questions about the enforceability strategy behind USRE047368E.
Reissued patents carry amplified validity risk in litigation
USRE047368E is a reissued patent, meaning its claims were corrected or broadened after original grant. Reissued patents face heightened prosecution history scrutiny and intervening rights defenses. Any company asserting — or defending against — a reissue patent should conduct a dedicated reissue-specific claim scope analysis before litigation commences.
Motion for Reconsideration as a termination strategy in patent cases
National Dentex Labs’ successful reconsideration motion demonstrates the value of revisiting early adverse rulings on dispositive legal grounds. Patent defendants should routinely evaluate whether a prior order contains clear legal error, particularly on threshold issues such as standing, § 101 eligibility, or claim definiteness, as reconsideration can achieve final judgment without trial.
3D v National — key questions answered
A dismissal with prejudice in this case means all of 3D Scan Guide LLC’s infringement claims under USRE047368E against National Dentex Labs are permanently extinguished. The plaintiff cannot refile the same claims against the same defendant. Final Judgment was entered under Fed. R. Civ. P. 58 following the court granting defendant’s Motion for Reconsideration.
USRE047368E is a reissued U.S. patent covering a modular template for drilling holes and a method of making the same, applied in dental prosthetic and implant guide fabrication workflows. As a reissue, it reflects post-grant claim correction by the USPTO and may carry different scope than the original patent. Reissued patents are subject to intervening rights defenses for third parties who practiced the technology before reissue.
National Dentex Labs’ successful Motion for Reconsideration (Doc. #49) led directly to with-prejudice dismissal of all claims. Reconsideration is typically granted only where a court identifies a clear error of law, newly available evidence, or an intervening change in controlling authority. Achieving final judgment via reconsideration — rather than summary judgment or trial — suggests the defendant identified a threshold legal defect in the plaintiff’s case.
Yes. A with-prejudice dismissal constitutes a final, appealable order. 3D Scan Guide LLC could seek review before the U.S. Court of Appeals for the Federal Circuit, which has exclusive appellate jurisdiction over patent cases. However, the public record does not indicate whether an appeal has been filed, and the standard of review would require demonstrating that the district court abused its discretion in granting reconsideration.
3D Scan Guide LLC was represented by Michael Scott Fuller of Garteiser Honea PLLC, a Texas-based firm known for patent assertion litigation. National Dentex Labs was represented by Alexander Steven Czanik, Ava M. Bowden, and Lucas Thomas Elliot of Frost Brown Todd LLP. The case was presided over by Judge Alfred H. Bennett in the Southern District of Texas.
