Case Overview
The Parties
⚖️ Plaintiff
Israel-based dental technology innovator holding patents related to intraoral scanning and three-dimensional dental measurement systems.
🛡️ Defendant
U.S. entity of Danish dental technology company 3Shape A/S, a global leader in digital dentistry solutions, including its widely adopted TRIOS intraoral scanner line.
Patents at Issue
This landmark case involved two patents covering foundational methods and systems used in digital dental scanning workflows. These patents protect technology central to the burgeoning digital dentistry market.
- • US 6,402,707 — Foundational intraoral scanning technology related to three-dimensional data acquisition. Claims 1 and 37 found infringed.
- • US 9,222,768 — Covering related dental scanning methodologies.

The Verdict & Legal Analysis
Outcome
A Western District of Texas jury returned a **unanimous verdict for Densys on April 8, 2022**, finding that 3Shape infringed Claims 1 and 37 of the ‘707 Patent and that the infringement was **willful**. The court subsequently denied all equitable relief sought by 3Shape.
The **final judgment totaled $17,868,182.00**, comprising:
This verdict underscores the high-stakes nature of dental imaging patent infringement disputes, signaling continued aggressive enforcement of legacy scanning patents.
Key Legal Issues
The willfulness determination is among the most consequential elements of this verdict. Under *Halo Electronics, Inc. v. Pulse Electronics, Inc.* (2016), willful infringement requires subjective recklessness. A willfulness finding opened the door to **enhanced damages up to three times** the compensatory award under 35 U.S.C. § 284, with the court applying a **25% enhancement** in this case.
The jury also found that **3Shape induced others to infringe** Claims 1 and 37 of the ‘707 Patent, requiring proof that the defendant actively encouraged a third party’s direct infringement with knowledge that the acts constituted infringement.
Following a bench trial, the court **denied all equitable defenses** raised by 3Shape, reinforcing that such defenses face a high bar and are rarely successful when direct infringement and willfulness have already been established by a jury.

The case involved U.S. Patent No. 6,402,707 and U.S. Patent No. 9,222,768, covering intraoral scanning methods and systems used in digital dental workflows.
The jury found 3Shape’s infringement of Claims 1 and 37 of the ‘707 Patent to be willful, supporting enhanced damages of approximately $2.97 million above the $11.875 million compensatory award.
The outcome validates aggressive enforcement of dental scanning patents, including older-priority-date patents, and may encourage similar assertion strategies by other patent holders in the digital dentistry space.
Companies can protect themselves by conducting freedom-to-operate (FTO) analysis before finalising product designs, documenting design evolution thoroughly, considering design-around strategies for high-risk elements, and filing their own patents early in the product development cycle.
