Corey T. Leggett

Corey Leggett leverages his well-rounded experience in prosecution and litigation to see beyond short-term resolutions, and craft the unique strategies that help clients get the most out of their intellectual property.

Corey's diverse patent practice involves assisting U.S. and foreign clients secure patent rights for inventions in the commodities, industrials, technology, and healthcare sectors. As a problem-solving advocate, Corey also represents clients in intellectual property disputes in district courts, at the International Trade Commission (ITC), and before the Patent Trial and Appeal Board (PTAB) at the United States Patent and Trademark Office (USPTO).

On the litigation side, Corey embraces each case as an opportunity to analyze the client's business objectives, and provide guidance towards a resolution that supports those objectives. In addition to researching and formulating non-infringement and invalidity positions, he has drafted pleadings, contentions, pre-trial motions, and claim construction briefs. Patent disputes continue to evolve, and parties have new options to litigate in alternative forums, such as the ITC and USPTO. Corey represents clients in all of these forums and coordinates the interplay between them, notably how and when to utilize USPTO post-grant proceedings.

Corey has also written and prosecuted numerous patent applications directed to imaging technologies, including task allocation methods implemented in computer networks, digital image manipulation, image processing, thermal printing, and digital display devices. He has further prosecution experience in the areas of commodity and specialty chemical products (including dye coatings, polymer films, and heat transferable materials) and industrials (e.g., systems involving gasification, combustion, electrolysis, and separations processes).
