Case Overview
After 585 days of litigation in the Northern District of Georgia, **Osseo Imaging, LLC v. Carestream Dental, LLC** (Case No. 1:23-cv-03116) concluded with a mutual stipulated dismissal with prejudice — a resolution that closes all claims and counterclaims permanently without a court ruling on the merits. Filed in July 2023 and closed in February 2025, this dental imaging patent infringement case centered on two issued U.S. patents covering **dental and orthopedic densitometry modeling** technology.
The case carries meaningful signals for IP professionals and R&D teams operating in the medical imaging and dental diagnostics space, where patent portfolios are increasingly weaponized to protect or challenge market positions. Stipulated dismissals of this kind — bilateral, with each party bearing its own costs — often reflect negotiated resolution dynamics that practitioners should understand when advising clients on litigation posture. For patent attorneys tracking dental technology patent litigation trends, this case underscores how quickly even well-resourced infringement actions can reach private resolution.
The Parties
⚖️ Plaintiff
A patent-holding entity asserting intellectual property rights in dental and orthopedic imaging technology, operating with a patent assertion strategy.
🛡️ Defendant
A well-established developer and distributor of dental imaging systems and software for clinical diagnostics and oral healthcare settings.
Patents at Issue
This case involved two U.S. patents asserted against Carestream Dental, covering fundamental dental and orthopedic densitometry modeling technology:
- • U.S. Patent No. 6,381,301 B1 — An earlier-generation patent covering foundational methods in dental and orthopedic densitometry modeling.
- • U.S. Patent No. 8,498,374 B2 — A continuation or related patent expanding on densitometry system and method claims.

The Verdict & Legal Analysis
Outcome
The case terminated on February 18, 2025, through a stipulated dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The dismissal was bilateral: Osseo Imaging dismissed all claims, and Carestream Dental dismissed all counterclaims. Both parties agreed to bear their own costs and attorneys’ fees, marking the end of 585 days of litigation.
Legal Significance of the Dismissal
The “with prejudice” bilateral structure is notable. Unlike a dismissal without prejudice — which would permit refiling — this outcome extinguishes Osseo’s ability to re-assert these patents against Carestream on the same accused products, and eliminates Carestream’s counterclaims permanently. For patent practitioners, this represents a clean exit strategy that avoids judicial determination of validity, which could have created adverse precedent for either party’s broader IP position.
