Mintz

Firm overview. Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C. ("Mintz") is an Am Law 100, full-service firm headquartered in Boston (One Financial Center), with roughly 550–600+ attorneys across offices in Boston, Los Angeles, Miami, New York, San Diego, San Francisco, Washington, DC, and Toronto (mintz.com; ICLG firm profile). Its Intellectual Property Division is a core platform—over 130 IP professionals, including 40+ with PhDs—and the patent litigation group is ranked by Legal 500 in "Patents: litigation (full coverage)" (legal500.com).

IP litigation specialty. The firm is best known for high-stakes Section 337 litigation at the USITC and for semiconductor/GPU and wireless/SEP disputes, alongside a substantial life-sciences patent practice. Reported matters span graphics processors (AMD v. TCL/Realtek), standard-essential 5G patents (Ericsson's campaign against Lenovo/Motorola), server-memory SEPs (Netlist v. SK Hynix), and BPCIA/biosimilar litigation (Amgen's Prolia/XGEVA cases) (Bloomberg Law; Law360; World IP Review 2025). Michael Renaud has stated the firm has handled "more semiconductor cases than virtually any other US firm."

Side preference. In the tracked matters, Mintz appears exclusively on the defense side (2 defendant appearances, 0 plaintiff-side), both led by Robert T. Vlasis III. Firm-wide, however, the practice works both sides of the docket: it prosecutes for operating companies (AMD, Netlist, Ericsson) and defends accused infringers (Juul Labs, Eli Lilly strategy work), and Vlasis has first-chaired ITC trials for both complainants and respondents (mintz.com; Legal 500).

Notable cases and outcomes. Headline results include AMD's ITC victory over TCL/Realtek, which produced cease-and-desist and exclusion orders barring infringing smart TVs (Bloomberg Law, Jan. 2025); a full-Commission defense win for Juul Labs against Altria's NJOY patents (Am Law Litigation Daily); and a landmark Federal Circuit reversal of a PTAB IPR cancellation for Straight Path IP Group—reportedly the first opinion to entirely reverse and remand such a decision (mintz.com). The two tracked Vlasis matters are listed as "Untitled" in the case data, so they cannot be named here; Vlasis is also a named author on the firm's commentary regarding the Federal Circuit's Apple Watch ITC exclusion-order affirmance and Bissell v. ITC, though his role in those cases is not confirmed.

PTAB / IPR practice. Mintz has a standout IPR practice: Patexia's 2025 PTAB report ranked it the 12th most active and 13th best-performing firm representing patent owners (33rd overall), with William Meunier the 6th best-performing patent-owner attorney nationally (Patexia/mintz.com). Notable IPR work includes preserving 105 of 107 claims across 14 instituted IPRs for ELM 3DS. Its ITC bench is equally strong—No. 7 most-active complainant firm in Patexia's 2025 ITC report, and one of a select few firms to secure a General Exclusion Order.

Key partners / practice leaders. Michael T. Renaud (Chair, Intellectual Property Division, and co-chair of patent litigation; IAM Patent 1000) and Robert T. Vlasis III (Co-chair, ITC Practice; IAM Patent 1000; Legal 500 "Key Lawyer") are the leading names, alongside Thomas Wintner (co-chair, patent litigation, per Legal 500), Siegmund Gutman (Chair, Life Sciences Litigation, added from Proskauer in 2024), and ITC trial partners James Wodarski and William Meunier (mintz.com; World IP Review 2025).
