3:22-cv-07335
N.D. Cal.Jun 30, 2023Background
- Dental Monitoring (plaintiff) owns a portfolio including three patents asserted here (U.S. Nos. 10,755,409; 11,049,248; 11,109,945) directed to AI/neural‑network methods for dental image analysis and an aligner‑evaluation score.
- Align Technology (defendant) launched Invisalign Virtual Care and later an Invisalign Virtual Care AI platform that has patients capture and submit intraoral photos via an app for remote monitoring.
- Dental Monitoring alleges Align copied its technology after meetings between executives, and asserts direct (35 U.S.C. §271(a) and §271(g)), indirect (§271(b), (c)), and willful (§284) infringement.
- Align moved to dismiss under Rule 12(b)(6), arguing (a) §271(g) inapplicable because claimed methods produce abstract information, (b) §271(a) fails because multiple actors perform method steps, (c) pleading is insufficient under Iqbal/Twombly, and (d) willful/indirect claims lack plausible knowledge allegations.
- Court denied dismissal of direct infringement under §271(a) (plausible allegations that Align directs/controls patient performance and testing), but granted dismissal as to §271(g), and granted dismissal of willful and indirect infringement for failure to plausibly plead knowledge.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether accused product is a “product made by a patented process” under §271(g) | Patented methods produce tangible results (scores/messages) eligible under §271(g) | Claimed methods only generate abstract/digital information (messages, values, scores), not manufactured physical products | Dismissed §271(g): abstract information not a physical product under §271(g) |
| Whether all method steps are attributable to a single entity under §271(a) (direction/control) | Align performs steps in testing and conditions Virtual Care benefits on patients using the app and following instructions, so Align directs/controls patient steps | Patients capture images; Align does not itself perform all steps in normal operation | Denied dismissal §271(a): pleaded testing-based performance and plausible direction/control over patients survives pleading stage |
| Whether the complaint pleads infringement sufficiently under Iqbal/Twombly | Complaint gives step-by-step description of accused platform and maps claim limitations to platform behavior; further detail is in Align’s possession | Pleading recites claim elements and uses generic AI terms; insufficient specificity to plead element‑by‑element infringement | Denied dismissal on pleading sufficiency: plaintiff pleaded a plausible short/plain statement and factual mapping adequate for discovery |
| Whether willful and indirect infringement adequately pleaded (knowledge) | Pre‑suit meetings, exchanges, and awareness of plaintiff’s patent portfolio put Align on notice of patents and infringement | Knowledge of a portfolio or meetings does not show knowledge of specific asserted patents or their infringement; no notice letter was sent | Granted dismissal of willful and indirect claims: plaintiff failed to plausibly plead knowledge of the specific patents/that Align infringed them |
