Armstrong Teasdale, one of the nation's largest 200 law firms with offices in the United States and China, provides essential business related legal services to clients across a wide range of industries. Intellectual property, our fastest growing practice area, is one of the firm’s core strengths. Our team of more than 80 IP professionals, including 45 attorneys who are registered to practice before the U.S. Patent and Trademark Office, provides both administrative and litigation counsel in all key areas including copyright, trademark, patent, and trade secrets. In addition to law degrees, many of our IP attorneys have advanced degrees and work-related experience in scientific areas and understand clients’ complex inventions and ideas. We are particularly known for our patent infringement litigation successes, many of which have been obtained in “hotbed” federal districts where high stakes patent suits often land.
