Medit Corp. v. 3Shape Inc.: Five-Patent Intraoral Scanner Dispute Ends in Dismissal With Prejudice
Medit Corp. filed suit against 3Shape Inc. in the Western District of Texas, asserting five U.S. patents covering intraoral scanner technology. After 495 days of litigation, the parties jointly moved to dismiss the case with prejudice — a resolution consistent with a confidential settlement — with each side bearing its own attorneys’ fees.
Five-Patent Intraoral Scanner Battle Resolved by Joint Dismissal in W.D. Texas
On September 8, 2023, Medit Corp. — a South Korean dental technology company — filed an infringement action against 3Shape Inc. in the Western District of Texas, asserting five U.S. patents: US10695151B2, US10064553B2, US11368667B2, US11076146B1, and US9629551B2. All five patents relate to intraoral scanner technology, a fast-growing segment of digital dentistry. The accused product was 3Shape’s intraoral scanner, placing the litigation squarely in the competitive arena between two leading dental scanning hardware and software providers.
The case ended on January 15, 2025, when the court granted the parties’ joint motion to dismiss with prejudice under Fed. R. Civ. P. 41(a)(2). The dismissal with prejudice forecloses Medit from bringing the same patent claims against 3Shape in any future proceeding. Notably, the order states that the court retains jurisdiction to enforce ‘the Agreement,’ strongly suggesting the parties reached a private settlement — the financial and licensing terms of which remain undisclosed on the public record.
The 495-day duration suggests the parties litigated through at least the early stages of discovery or claim construction before reaching resolution. The mutual fee-bearing provision — each party covering its own costs — is a hallmark of negotiated exits and suggests neither side secured a decisive litigation advantage sufficient to compel the other to absorb fees. The existence of an underlying ‘Agreement’ referenced in the order, combined with the court retaining enforcement jurisdiction, is consistent with a cross-licensing arrangement or a covenant not to sue, though this cannot be confirmed from the public record.

Dismissed with prejudice: what the joint order means for both parties
Rule 41(a)(2) dismissal with prejudice — a final, court-ordered end
Under Fed. R. Civ. P. 41(a)(2), dismissal with prejudice at this stage requires a court order, which the parties sought jointly. ‘With prejudice’ is a final adjudication on the merits for preclusion purposes: Medit cannot re-file these five patent claims against 3Shape in any future action. The court retaining jurisdiction to enforce ‘the Agreement’ signals an underlying contract — typically a settlement or license — governs the ongoing relationship between the parties.
Permanent bar on re-filingMedit accepts finality — but likely secures commercial terms
By agreeing to dismiss with prejudice, Medit relinquishes the right to pursue these specific claims against 3Shape. However, the court’s retention of jurisdiction over ‘the Agreement’ strongly suggests Medit obtained something of commercial value — potentially a license fee, royalty stream, or covenant — in exchange. The five asserted patents remain valid and enforceable against third parties not covered by any agreement reached with 3Shape.
Patents remain enforceable vs. third parties3Shape gains certainty on these five patents — at a price
The dismissal with prejudice removes the litigation cloud from 3Shape’s intraoral scanner product line with respect to Medit’s five asserted patents. The mutual fee-bearing provision suggests 3Shape did not achieve an outright defense win — if it had, it would typically press for fee recovery under 35 U.S.C. § 285. The existence of an enforced Agreement implies 3Shape accepted some form of obligation in exchange for resolution, the scope of which is not public.
Cleared on these five claimsCompetitive dynamics in digital dentistry remain closely watched
Medit and 3Shape are among the most active patent filers in intraoral scanning. A privately resolved dispute of this scale — five patents, 495 days, W.D. Texas — is consistent with a broader IP licensing strategy rather than a desire for public precedent. Competitors and new entrants in dental scanning should assess whether the patents asserted here present FTO risks for their own product lines, particularly given Medit’s continued ownership of the asserted portfolio.

Official order — verbatim text
The order’s operative language — ‘DISMISSED WITH PREJUDICE, with each party to bear its own attorneys’ fees and expenses’ — has two key legal effects. First, dismissal with prejudice functions as a final judgment on the merits for claim-preclusion purposes, permanently extinguishing Medit’s right to reassert these five patents against 3Shape. Second, the explicit reference to ‘the Agreement’ and the court’s retained enforcement jurisdiction indicates the dismissal is not a unilateral withdrawal but is tied to a private contract — the terms of which are not reflected in the public docket.
US10695151B2 and four further patents — intraoral scanner systems and methods
The five asserted patents — US10695151B2, US10064553B2, US11368667B2, US11076146B1, and US9629551B2 — span application filings from 2012 through 2021, reflecting a sustained and layered prosecution strategy by Medit in intraoral scanning. The earliest priority, underlying US9629551B2 (App. No. US14/232363), suggests a technology foundation established over a decade ago. More recent grants including US11368667B2 and US11076146B1 — filed in 2021 — indicate active continuation activity extending patent coverage into the 2030s.
Intraoral scanners are a high-value segment in digital dentistry, enabling chairside 3D impressions that replace traditional mold-based workflows. Medit and 3Shape are among the dominant commercial players, and patent coverage in this space — particularly around scan data acquisition, processing, and visualization — is a critical competitive differentiator. The breadth of Medit’s five-patent assertion, spanning over a decade of prosecution, signals that this portfolio was built with enforcement in mind. Competitors designing or selling intraoral scanners in the U.S. should treat these patents as live FTO considerations.
Should you run an FTO against US10695151B2 and Medit’s intraoral scanner portfolio?
Any company developing, manufacturing, or distributing intraoral scanners or related dental imaging hardware in the U.S. should treat Medit’s five-patent portfolio as a material FTO risk. The combination of early-priority patents (US9629551B2) and recent continuation grants (US11368667B2, US11076146B1) means claim coverage may extend to modern scanning architectures even if the original filings predate your product design. The W.D. Texas enforcement of these patents against a major competitor confirms Medit’s willingness to litigate.
PatSnap Eureka’s FTO Search Agent can map each of the five asserted patents against your product’s technical specifications — from scan data acquisition hardware to imaging algorithms — identifying claim overlap and prosecution history estoppel that may limit scope. Eureka can also surface Medit’s broader continuation family and pending applications not yet asserted, giving R&D and legal teams early visibility into claims that could become enforcement tools. Run a structured FTO before your next product launch or investor due diligence round.

What this case signals for the digital dentistry IP landscape
A five-patent joint dismissal with a retained-jurisdiction order in W.D. Texas is a signal worth decoding for any company operating in intraoral scanning.
W.D. Texas remains a credible venue for dental technology patent enforcement
Medit’s choice of the Western District of Texas — even post-TC Heartland — demonstrates that this venue continues to attract international patent holders in hardware-adjacent tech sectors. Companies with intraoral scanning products sold in the U.S. should factor W.D. Texas exposure into their IP risk frameworks, particularly if headquartered outside the U.S. like 3Shape.
A five-patent assertion strategy signals portfolio depth, not a single-patent bet
Asserting five patents across multiple application numbers suggests Medit structured its complaint to survive potential IPR or invalidity challenges on any single patent. Competitors should audit all five patents — not just the lead case — when assessing freedom to operate, and consider whether continuation filings extend coverage beyond the asserted grants.
Medit v 3Shape — key questions answered
The case was dismissed with prejudice on January 15, 2025, pursuant to a joint motion by both parties under Fed. R. Civ. P. 41(a)(2). Each party agreed to bear its own attorneys’ fees. The court retained jurisdiction to enforce ‘the Agreement,’ strongly suggesting a private settlement was reached, though its terms are not public.
Medit asserted five U.S. patents: US10695151B2, US10064553B2, US11368667B2, US11076146B1, and US9629551B2. All five relate to intraoral scanner technology. The application filing dates range from 2012 (US14/232363) to 2021 (US17/533403 and US17/206581), indicating a broad prosecution strategy spanning over a decade.
Dismissal with prejudice operates as a final adjudication on the merits for preclusion purposes. Medit is permanently barred from re-filing the same patent infringement claims against 3Shape based on these five patents. However, the five patents remain valid and enforceable against other third parties not covered by the terms of whatever agreement the parties reached.
Under Kokkonen v. Guardian Life Ins. Co. (1994), a district court may retain jurisdiction to enforce a settlement agreement if it expressly incorporates the agreement or retains jurisdiction in the dismissal order. The January 2025 order explicitly retains jurisdiction to enforce ‘the Agreement,’ indicating the parties’ private settlement was incorporated by reference and remains subject to court oversight.
Medit’s five asserted patents span application filings from 2012 to 2021, with more recent continuation grants active potentially into the 2030s. Companies developing or selling intraoral scanners in the U.S. face risk from both the granted patents and any pending continuations not yet asserted. The W.D. Texas filing confirms Medit’s enforcement posture. A structured FTO analysis across the full Medit portfolio is advisable for any company active in dental scanning hardware or software.
