A. Justin Poplin

Justin Poplin is a registered patent attorney and served as Chair of the Prosecution & Transactions department in the Lathrop Gage LLP Intellectual Property division from 2013 to 2016. (Lathrop Gage is one of two firms that combined to form Lathrop GPM in 2020.) Because he efficiently prevents and solves problems in ways that minimize disruption to their business, some clients utilize Justin as outside general counsel. Industry groups, business incubators, and schools often request that he present on legal issues since he conveys complex topics in plain English.

Companies of all size—from large multi-national corporations to startups—rely on Justin’s legal advice on patent, trademark, copyright, trade secret, licensing, and confidentiality issues. He has been the lead patent attorney in litigated matters and has prepared and conducted inter partes reviews, inter partes and ex parte reexaminations, supplemental examinations, and broadening and narrowing reissues. He has aided clients with obtaining, enforcing, licensing, invalidating, and avoiding infringement of patents and trademarks in a wide range of technologies, and he is responsible for managing intellectual property portfolios globally.  

Justin argued and won some of the earliest inter partes review (IPR) cases, including one case against a large Johnson & Johnson subsidiary and another case representing Munchkin, and his docket has over 75 IPR cases. The Munchkin case is the first case invalidating a design patent through IPR. He has also successfully argued appeals at the U.S. Court of Appeals for the Federal Circuit. Audio recordings of Federal Circuit appearances on behalf of Munchkin and Shinn Fu Company of America can be accessed here and here.  

Example technologies include aircraft components and systems; alcohol monitors; alternative-fuel engines; automotive components and systems; automotive repair equipment; baby products; computer software; elevators; force dispersion; games and sporting equipment; glass anti-break; hair accessories; hardware; hunting and fishing equipment; HVAC; hydraulic lifting devices; injection-molding; jewelry; kitchenware; lawn/turf care; medical devices; oil and gas; pharmaceutical dispensers; plumbing devices; power generation; power tools; printing equipment; shoes; structural building components; theft-deterring devices; and trailers.

Justin wrote and prosecuted the patent portfolio for a company that developed an industry-leading video-content and recommendation engine. The company was later acquired by Hulu.
