Danielle V. Tully — Patent Litigation Practice Summary

Danielle V. Tully (also Danielle Vincenti Tully) is a first-chair IP trial lawyer based in New York, currently a partner in Orrick, Herrington & Sutcliffe's Intellectual Property Group (joined January 2026). She spent the bulk of her career at Cadwalader, Wickersham & Taft — where she rose to co-chair of the Global Litigation and Intellectual Property Groups — after starting at the IP boutique Morgan & Finnegan LLP and moving to Cadwalader with that group. Her practice spans patent, trade secret, copyright, and trademark litigation across pharmaceuticals, medical devices, computer hardware and software, cybersecurity, digital television, and telecommunications. She holds a biology degree, which underpins her medical-device and life-sciences work.

Her tracked docket is uniformly defense-side (2 of 2 appearances, both for defendants at Cadwalader): she defended Brother Industries against Flexiworld Technologies, a serial non-practicing entity asserting printer/scanner-related patents (including cases filed in the Western District of Tennessee), and defended Brother in related litigations in the Eastern District of Texas, Delaware, and Central District of California. Her broader practice likewise skews heavily toward defending operating companies — including AngioDynamics, AT&T Mobility, and Hyland — against NPEs and competitors, with occasional patent-holder-side work (e.g., Convolve v. Compaq; IBM as an ITC complainant).

Her most prominent result is C.R. Bard v. AngioDynamics (D. Del.), where she led the defense through two jury trials and Federal Circuit proceedings. In June 2023, after Bard won a jury verdict, the district court granted judgment as a matter of law — the first Delaware JMOL invalidation since 2019 — holding Bard's vascular access port patents invalid as anticipated, indefinite, and ineligible; the Federal Circuit affirmed in December 2025, and the parties settled in March 2026. Her practice includes post-grant and inter partes proceedings before the USPTO, and she co-authored a Law360 article on Federal Circuit deference to PTAB decisions (2020 Burton Award for Distinguished Legal Writing), though her PTAB docket does not appear to be a volume practice.

She is admitted in New York (2005), registered before the USPTO, and admitted to the Federal Circuit and the Eastern, Southern, and Northern Districts of New York; she earned a B.S. in Biology (summa cum laude) and a J.D. from Boston College. Note: She should not be confused with L. Danielle Tully, a Brooklyn Law School legal-writing professor.
