Michael B. Powell

Specialty / Focus. Michael B. Powell is a patent litigator whose practice spans medical devices, wireless telecommunications, consumer products, and computer hardware/software, with additional experience in cybersecurity and enterprise content management. Per his firm profile, he handles district court litigation nationwide (Delaware, Eastern/Western Texas, California), ITC investigations, and Federal Circuit appeals, and he counsels on standards-essential patents, IP licensing, and validity/non-infringement opinions.

Side Preference. His tracked docket is entirely defendant-side: two appearances for defendants (Flexiworld Technologies v. Brother Industries and a related Flexiworld action), both while at Cadwalader. Web-searchable matters reinforce a strong operating-company defense practice — Brother, AngioDynamics, AT&T Mobility, Dentsply Sirona, Qualcomm, and Hyland — including defending against NPE assertions (Flexiworld is classified as an NPE in Stanford's NPE Litigation Database).

Firm Context. Powell built his practice at Cadwalader, Wickersham & Taft in New York, where he was part of the firm's IP trial team, and is now a partner in Orrick's Intellectual Property Group in New York (his Orrick bio notes the Cadwalader experience predates joining Orrick).

Notable Cases / Outcomes. His most prominent matter is C.R. Bard v. AngioDynamics (D. Del.), where the Cadwalader team he was on won a complete defense verdict against claims seeking over $200 million — on non-infringement, invalidity, and § 101 ineligibility — later affirmed per curiam by the Federal Circuit. He also represented Brother in multiple printer/scanner litigations (E.D. Tex., D. Del., C.D. Cal.), including the tracked Flexiworld v. Brother cases filed in the W.D. Tenn. in 2022, and defended AT&T Mobility in 4G/LTE litigation, obtaining summary judgment of non-infringement and invalidation of asserted claims.

PTAB / IPR Experience. He has appeared before the PTAB, serving as backup counsel (pro hac vice) in CBM2020-00012, Quantile Technologies v. TriOptima AB, where the Board's final written decision invalidated all 46 challenged claims under § 101.

Bar / Education. Admitted in New York (2013) and the District of Columbia; J.D., NYU School of Law (2012, cum laude); B.A. in Molecular and Cell Biology, UC Berkeley (2009).
