The unauthorized use of patents by the federal government is generally connected with procurement. The government purchases goods and services from federal contractors and the government wants the best products and services without delay; therefore, "the government will not refuse to award a contract on the grounds that the prospective contractor may infringe a patent," as per 48 C.F.R. 27.102(b).
