United States United States - Texas Nelson Bumgardner PC

Nelson Bumgardner is a litigation boutique specialising in patent litigation and post-grant proceedings before the US Patent and Trademark Office (USPTO). Nelson Bumgardner prides itself on offering ‘beginning-to-end’ representation in complex patent matters, including all aspects of discovery and case preparation, any intervening proceedings before the USPTO (eg, inter partes review and covered business method proceedings), and trial and appeal. The firm’s attorneys possess high academic credentials and a wealth of experience, and are prepared to protect their clients’ interests in venues across the United States.

While Nelson Bumgardner began as a litigation and trial boutique, specialising in patent infringement matters, it has extended its practice to represent clients in post-grant challenges before the USPTO. Representing clients in these proceedings is a natural extension of the firm’s practice, given that most of the firm’s attorneys are licensed to practise before the USPTO.
