    The Yale University Office of Cooperative Research (OCR) was founded in 1982 and charged with extending and expanding Yale University's interaction with the private sector. The duties of the OCR include oversight for patenting and licensing activities, university inventions, and contractual relationships between faculty and industry. OCR staff work with Yale researchers to identify inventions that may ultimately become commercial products and services useful to the public. OCR staff also engage in industrial partnerships to license Yale inventions. The Office of Cooperative Research helps launch several new ventures every year. Today there are over 40 ventures commercializing technologies out of Yale that range from new medicines and medical devices to cleantech products and software.
