About Law Office Of Vincent G. LoTempio PLLC, Patent Attorney
The Law Office of Vincent G. LoTempio PLLC is an intellectual property practice located on Main Street in Buffalo, New York, led by Vincent LoTempio, a registered U.S. patent attorney with more than 25 years of experience. The firm’s stated focus is helping inventors and business owners secure and defend the rights behind their ideas, brands, and creative work. Its service list covers patent search and patent application drafting; trademark search, filing, registration, renewal, prosecution, and infringement litigation; copyright registration; and invention assistance for individuals developing a concept for the first time.
LoTempio is described on the firm’s site as a recognized Super Lawyer and a featured expert on the History Channel program Million Dollar Genius. Robert Cerasa is listed alongside him, and reviewers frequently name Margo and the wider team as part of the experience. The office offers a free consultation, publishes a blog, podcast, and video content, and maintains an IP definitions resource and newsletter for clients who want background before committing to a filing.
The practice serves a broad mix of clients: independent inventors, small business owners, game and product developers, filmmakers, and established companies returning for repeat filings. Reviews describe work on patent applications, trademark registrations, copyright questions, and a contested trademark opposition that proceeded over roughly two years. Some clients have worked with the firm since 2011 and have filed multiple patents through the office.
What recurs across the review record is communication. Clients repeatedly note that the firm explains patent and trademark procedure in plain language, answers questions during the initial call, and keeps them informed at each stage. Reviewers also cite responsiveness, punctuality on filing tasks, and a no-pressure approach, with several noting that guidance was offered even when the conversation did not lead to paid work. Others mention being referred elsewhere when an inquiry fell outside the firm’s practice area.
Not every proposed mark can be registered, as one visitor learned when a chosen name was deemed too generic. Certain matters fall outside the firm’s IP scope and are handled by referral. And some trademark disputes run long, with one client’s opposition lasting about two years before resolution. Those caveats aside, the firm’s 4.9 rating across 111 reviews reflects a consistent pattern of satisfied inventors and business owners.
