Wolf Greenfield
Firm overview:
Wolf, Greenfield & Sacks is one of the largest US law firms exclusively focused on IP, representing a wide range of clients from startups and universities to Fortune 500 companies. The firm has a strong reputation for patent work; a peer comments that when it comes to prosecution, “I don’t think anyone can do better than them, at least in biotech … They are very responsive”. For complex patent matters, “I would definitely call them,” the peer adds.
Wolf Greenfield has ranked as the second-most active law firm for biotech patent prosecution, and filed over 6,700 patent applications overall in 2025. The firm received dual recognition in the inaugural LSPN Awards USA 2025, organised by WIPR sister title LSIPR, winning both IP Boutique of the Year and Life Sciences Prosecution Firm of the Year.
The team is also a credible choice for large technology clients, and has handled patent procurement and portfolio management for Sony for two decades.
Also recognised for its contentious services, Wolf Greenfield has represented Sony in patent litigation and inter partes review matters. The firm’s Patent Trial and Appeal Board (PTAB) team has a strong track record of success; wins include successfully challenging a patent held by a non-practising entity (NPE) that was asserted against client Google.
Team overview:

Shareholder Daniel Young is singled out by a peer as a name to know at the firm for patent work. His practice focuses on developing and maintaining patent portfolios covering biologics and small molecules, as well as addressing IP matters in transactional matters and more.
Other stand-out professionals include shareholder Jason Honeyman, who represents clients in the mechanical/electromechanical fields in patent and trademark litigation, post-grant challenges to patent validity, technology licensing, and more.
