Charles R. Macedo

I'll research Charles R. Macedo's professional background before drafting.

Let me verify the specific tracked cases and additional background.

Let me confirm the outcome of the AlmondNet v. Yahoo matter and Macedo's role there.

Professional Summary — Charles R. Macedo

Practice focus. Macedo is a New York–based IP litigator and registered patent attorney whose practice spans patent, trademark, and copyright law, with an emphasis on complex litigation and appellate work. His technical background (a physicist by training) has supported matters involving computer-implemented and business-method inventions — online advertising, financial services, e-commerce and payment systems, semiconductors, batteries, consumer electronics, and cosmetics — and his current firm biography highlights AI/machine-learning, blockchain, and related technologies. His case mix reflects both district-court litigation and appellate/amicus work.

Side preference. The tracked appearances show a genuine two-sided practice rather than a single-side specialty: he appeared as lead counsel for the plaintiff in AlmondNet, Inc. v. Yahoo! Inc. (ad-targeting patents asserted by the AlmondNet/Intent IQ/Datonics family) and as supervising counsel for the defendant in AML IP, LLC v. Orveon Global US LLC (S.D.N.Y. 2025), an e-commerce/electronic-token patent suit brought by an entity identified in third-party databases as a non-practicing entity against an operating cosmetics company (Orveon/bareMinerals). He also describes developing both "offensive and defensive" portfolio strategies, so the two counts are consistent with a mixed plaintiff/defendant practice.

Firm context. Macedo has long been associated with Amster, Rothstein & Ebenstein LLP (New York), a boutique IP firm, where he has been listed as a partner; more recent firm and directory pages list him as Of Counsel. No other law-firm history surfaced in the sources reviewed.

Notable matters and outcomes. The most prominent tracked case is AlmondNet v. Yahoo! (E.D.N.Y. 2016; transferred to D. Del. in 2018), involving a multi-patent assertion over behavioral/off-site targeted advertising; Yahoo filed parallel PTAB covered-business-method reviews (e.g., CBM2017-00046 and -00052) against some of the asserted patents. Separately, a 2024 jury verdict awarding AlmondNet roughly $122 million against Amazon involved the same '639 and '139 patents that appeared in the Yahoo litigation, though that case is not among his tracked appearances and should not be attributed to him on this record. On the appellate side, sources list him as counsel of record or amicus counsel in U.S. v. Arthrex, American Axle v. Neapco, Return Mail v. U.S. Postal Service, St. Regis Mohawk Tribes v. Mylan, plus amicus submissions in Alice, Mayo, and Cuozzo, and a 2024–25 cert petition in Island Intellectual Property LLC v. TD Ameritrade (Rule 36 affirmances / § 101 eligibility at summary judgment).

PTAB / IPR. Yes — sources describe him as having served as lead counsel for petitioners that invalidated challenged claims in inter partes reviews and for patent owners whose claims survived IPR and CBM proceedings, and he has co-chaired the New York Intellectual Property Law Association's PTAB Committee.

Bar / education. Admitted in New York (1990), D.C., Wisconsin, and Michigan, and registered to practice before the USPTO; former sole law clerk to Judge Daniel M. Friedman of the U.S. Court of Appeals for the Federal Circuit (1989–90). B.S./M.S. in physics, The Catholic University of America (1986); J.D., Columbia Law School (1989). (Note: the "partner" vs. "Of Counsel" designation and some bar-admission details vary across directory sources and should be confirmed with the firm.)
