McNeill Baur

McNeill Baur PLLC is a women-owned intellectual property boutique firm founded in 2014. While the firm operates in a fully remote environment, it has office locations in Cambridge, Massachusetts; Dublin, California; and Johns Creek, Georgia. Vault recognizes McNeill Baur as a top midsize law firm, and its attorney count is estimated to be between 1 and 50. The firm is not presently ranked by AmLaw or Chambers and Partners.

The firm's stated focus is exclusively on life sciences, with deep expertise in biotech and pharmaceutical patent prosecution and counseling. The firm's website highlights that its attorneys have advanced degrees in life science or chemistry disciplines. However, the firm’s single tracked litigation appearance is in the mechanical and electronics sector, representing the plaintiff in a case involving video game controller patents. This indicates a capability to handle complex patent litigation outside its primary focus area. Based on its limited tracked history, the firm has exclusively represented patent owners.

McNeill Baur's most notable litigation success is its representation of the plaintiff, Ironburg Inventions Ltd., against Valve Corporation. In this matter, attorney Robert P. Greenspoon is listed as lead counsel for the firm. The case resulted in a jury verdict of willful infringement and an award of over $4 million in damages to Ironburg, a verdict that was upheld on appeal. The litigation also involved significant proceedings before the Patent Trial and Appeal Board (PTAB) and a key Federal Circuit decision on the scope of IPR estoppel, demonstrating the firm's experience in handling contentious USPTO proceedings in parallel with district court litigation.

The firm’s key partners are recognized leaders in intellectual property. Rebecca A. McNeill is the Founding and Managing Partner and is consistently recognized as a leading patent professional by publications such as Managing Intellectual Property, IAM Patent 1000, and LMG Life Sciences. While the authoritative case data lists Robert P. Greenspoon as lead counsel for the firm in its tracked case, public records as of 2026 indicate he is a partner at a different firm.
