Case Overview
The Parties
⚖️ Plaintiff
Michigan-based dental technology company known for developing patented Densah® Bur technology used in implant site preparation. VERSAH has built a focused IP portfolio around bone compaction techniques that preserve and condense bone rather than remove it — a differentiated approach in implant dentistry.
🛡️ Defendant
Headquartered in Englewood Cliffs, New Jersey, HIOSSEN is a subsidiary of Osstem Implant Co. and a recognized distributor of dental implant systems and related surgical components in the U.S. market. HIOSSEN’s product lineup competes directly in the surgical preparation tool segment targeted by VERSAH’s patents.
Patents at Issue
This landmark case involved three U.S. patents covering dental implant site preparation and bone compaction instrument technology. All three patents fall within the **dental implant preparation technology** domain, specifically addressing the mechanical and procedural aspects of bone compaction during implant placement.
- • US 9,526,593 B2 — covering dental implant site preparation methods and instruments
- • US 9,028,253 B2 — directed to bone compaction bur geometry and cutting configurations
- • US 9,022,783 B2 — relating to rotary instruments for osteotomy site preparation

The Verdict & Legal Analysis
Outcome
The New Jersey District Court administratively terminated Case No. 1:24-cv-10527 on February 9, 2026, following notification that the parties had reached a settlement agreement. The court’s order expressly clarified that the administrative termination **does not constitute a dismissal** under the Federal Rules of Civil Procedure. The parties were granted 60 days to file formal dismissal papers under **FRCP Rule 41**, or to request reopening if settlement terms could not be consummated. Absent either action, the court indicated it would dismiss the case **with prejudice and without costs**. Specific financial terms, licensing arrangements, and any injunctive relief provisions of the settlement were **not publicly disclosed**.
Legal Significance
While this case did not produce a published opinion or claim construction ruling, its significance lies in **VERSAH’s demonstrated willingness and capacity to enforce its dental bur patent portfolio** in federal court against a well-resourced competitor. The assertion of three related patents simultaneously is a recognized litigation strategy that increases pressure on accused infringers and complicates invalidity defenses by requiring separate challenges to each patent. The early settlement suggests the parties likely engaged in substantive settlement discussions before significant motion practice developed.

Three U.S. patents were asserted: U.S. 9,526,593 B2, U.S. 9,028,253 B2, and U.S. 9,022,783 B2 — all covering dental implant site preparation and bone compaction instrument technology.
The parties reported a settlement to the court, which entered an administrative termination order on February 9, 2026. Specific settlement terms were not publicly disclosed.
It reinforces VERSAH’s active enforcement posture and signals to competitors that its bone compaction patent portfolio will be defended in federal court, potentially influencing licensing negotiations industry-wide.
