Serving the Westchester Tech Corridor & Greater New York Metro

Weber Rosselli & Cannon LLP's global headquarters at 143 Broadway in Hawthorne, NY, is positioned at the central crossroads of Westchester County. Situated within the Town of Mount Pleasant—bordering Thornwood, Valhalla, and Pleasantville—our office provides effortless accessibility for corporate leadership, venture-backed startups, and research institutions throughout Westchester, New York City, Connecticut, and New Jersey.

Westchester County has established itself as one of the premier biotechnology and technology hubs in the Northeast. Located just minutes from major innovation landmarks—including the BioInc@NYMC incubator at New York Medical College in Valhalla, the Regeneron Pharmaceuticals campus in Tarrytown, and the Westchester Medical Center research corridor—our Hawthorne headquarters serves as a core legal resource for pioneering medical device developers, pharmaceutical scientists, and industrial technology companies.

Specialized Regional Focus: Life Sciences & Marine Engineering

Senior Partner Thomas Rosselli directs much of our firm's pharmaceutical, medical device, and chemical patent practice directly from the Hawthorne office. Drawing on his background in pharmacy and synthetic organic chemistry, Mr. Rosselli assists Westchester and NYC-area biotechs in structuring patent portfolios for microfluidic diagnostic arrays, targeted therapeutic delivery systems, and bio-compatible medical mechanisms[cite: 2].

Founding Partner Nathan Weber manages acquisition due diligence, Freedom-to-Operate (FTO) clearance opinions, and mechanical patent prosecution from our Hawthorne location. A graduate of the U.S. Merchant Marine Academy (USMMA) at Kings Point, NY, Mr. Weber brings practical marine and mechanical engineering insight to regional industrial firms and hardware pioneers across the Tri-State area.

Federal & Regional Court Practice

Our Hawthorne-based attorneys are admitted to practice before the United States District Court for the Southern District of New York (SDNY)—which holds jurisdiction over Westchester and NYC—as well as the Eastern District of New York (EDNY) and the U.S. Court of Appeals for the Federal Circuit. Whether defending complex patent claims at the federal courthouse in White Plains or managing USPTO prosecution, our local presence ensures responsive, trial-ready representation.
