Ropes & Gray represented Foundation Medicine in connection with the sublease of approximately 265,000 square feet at 400 Summer Street in Boston’s Seaport to Hasbro Inc. Ropes & Gray previously represented Foundation Medicine in the 16 story, 600,000+ square foot building with WS Development in 2019.
