Ashley DaBiere — Patent Litigation Practice Summary

Specialty / focus areas. DaBiere's practice at Desmarais LLP is IP litigation and counseling, with a pronounced life-sciences tilt. Her tracked and web-searchable matters span genomic diagnostics — noninvasive prenatal testing (Ravgen v. Ariosa Diagnostics) and liquid-biopsy cancer screening (Cold Spring Harbor Laboratory v. Guardant Health) — as well as consumer software (Weisner v. Google LLC, involving Google Maps location-tracking patents). This aligns with her undergraduate training in biological sciences/neurobiology (Cornell, 2019), and she is a registered USPTO practitioner.

Side preference. Per the tracked case list, DaBiere has one plaintiff appearance (designated lead counsel) and one defendant appearance (designated Of Counsel), so she works both sides — representing patentees/research institutions in life-sciences assertions and defending an operating company (Google) in software litigation. She is an Associate in Desmarais LLP's New York office, the boutique patent-litigation firm founded by John Desmarais; prior to joining, she was a summer associate at the firm and a legal-department intern at Catalent Pharma Solutions (2021). No in-house role.

Notable cases. DaBiere was part of the Desmarais team that won a four-day bench trial in Weisner v. Google LLC (S.D.N.Y.), where Judge Alvin Hellerstein dismissed the case with prejudice after finding the plaintiff committed inequitable conduct — including forging a co-inventor's signature on a USPTO revival petition — defeating a suit over five Google Maps patents. On the plaintiff side, she is admitted pro hac vice in Cold Spring Harbor Laboratory v. Guardant Health (D. Del.), where Cold Spring's willful-infringement claims survived Guardant's motion to dismiss (Oct. 2025), and she appeared in Ravgen v. Ariosa Diagnostics — part of the broader Ravgen campaign that produced the $272.5M LabCorp verdict (later enhanced to $372.5M) and a $57M Natera verdict, though those trials were led by other Desmarais partners before her involvement.

PTAB / IPR experience. She has IPR exposure: in Illumina v. Molecular Loop Biosciences (IPR2024-00964/00965), DaBiere was designated back-up counsel for patent owner Molecular Loop. Bar / education: New York (2024); USPTO Reg. No. 82,050; J.D., Duke Law, 2023 (cum laude); B.A., Cornell University, 2019.
