A pair of life sciences-focused patent attorneys have left Stradley Ronon Stevens & Young for Am Law 200 firm Armstrong Teasdale, aiming to reap the benefits of the larger firm’s recent investments in its intellectual property practice.

Bringing decades of experience and advanced degrees in chemistry and microbiology, partners Joseph Rossi and Paul Legaard said they relocated to the Philadelphia office of the St. Louis-based firm to capitalize on its name recognition and greater critical mass of IP professionals. Such benefits, they said, will deal them a better hand in recruiting and delivering enhanced services for clients.
