Matthew A. Karambelas

I'll research this attorney before drafting.

Let me dig deeper into specific matters and credentials.

Now let me check bar admission, education, and PTAB/IPR appearances.

Matthew A. Karambelas — Patent Litigation Practice Summary

Focus and forum. Karambelas is a Boston-based patent litigator whose practice is anchored in Section 337 litigation at the U.S. International Trade Commission, with parallel district court and Federal Circuit work. Mintz's own materials describe his subject-matter experience as spanning semiconductor manufacturing, microbiology and genetic engineering, graphics processing, telecommunications, medical-quality flocked swabs, and healthcare information systems — i.e., a hardware/software and life-sciences mix rather than a single technical niche. Publicly identified ITC engagements include semiconductor foundry disputes (GlobalFoundries against the major foundries), video streaming/codec matters, microbiology and oligosaccharide production, and vaporizer/ENDS technology. He has written repeatedly on ITC-specific issues such as the domestic industry requirement, the 100-day pilot program, and § 101 at the Commission.

Side preference. The tracked docket skews toward the complainant/patent-owner side: three of four appearances are plaintiff-side, one is defense-side, and he has served as lead counsel in three of the four. That matches the ITC-centric profile above, where Mintz has frequently represented complainants seeking exclusion orders. He is not a one-sided practitioner, however — the defense-side appearance and his respondent representations (including the Juul/NJOY matter discussed below) show regular work for accused importers as well.

Firm context. Karambelas is a Member at Mintz, Levin, Cohn, Ferris, Glovsky and Popeo in Boston, practicing in the firm's Intellectual Property Litigation group; he was elected to the membership in the firm's December 2023 member class. All four tracked appearances are Mintz matters, and no prior-firm history in patent litigation surfaced in searches. He was named an MIP "Rising Star" (2021, and again in the 2026 IP Stars rankings) and a Best Lawyers "Ones to Watch" honoree in Patent Law.

Notable matters and credentials. Verifiable highlights include the Mintz team's ITC defense win for Juul Labs in the NJOY/Altria vaporizer investigation, where the Commission affirmed a no-infringement finding and no exclusion order issued (the team was recognized as an Am Law Litigation Daily "Litigator of the Week" runner-up), and his involvement in the GlobalFoundries semiconductor enforcement campaign at the ITC and in district court. His docket activity also reflects work on DivX video-processing investigations and the AMD/Realtek-TCL dispute in the Eastern District of Texas. Note that some attributions here rest on firm press releases and service lists rather than on reported opinions, so case-specific roles should be confirmed against the dockets. On PTAB work, he has appeared in inter partes review proceedings — the public record shows him on patent-owner-side filings (e.g., IPR2020-00837) — but his public profile and commentary are ITC-focused, and the available sources do not establish a high-volume IPR/PGR practice. Bar/education: J.D. and B.A. (Mathematics and Political Science), Boston College; admitted in Massachusetts in 2014, and admitted to the U.S. Court of Appeals for the Federal Circuit and the U.S. District Court for the District of Massachusetts. He served as a judicial intern to Judge Dennis J. Curran of the Massachusetts Superior Court while in law school.
