Ropes & Gray confirmed this week the details of a spin-off of its patent prosecution practice, a landmark move unveiled by the firm in early March.

Haley Guiliano, a boutique firm specializing in patent prosecution and other intellectual property work, will officially separate from Ropes & Gray on Aug. 1. Joseph Guiliano, co-head of Ropes & Gray’s IP rights management practice in New York, and senior counsel James Haley Jr., a biopharmaceutical and life sciences expert, will be the new firm’s two name partners.
