CoStar Group and six luxury hotel chains have filed a motion to dismiss a proposed antitrust class action that claimed the defendants colluded to hike hotel room prices through the shared use of data analytics.

Smith Travel Research, which was acquired by real estate research firm CoStar in 2019, has provided benchmarking reports to the hotel industry since its founding in 1985. The reports include information such as occupancy rates, average daily rates and revenue per available room.
