 Such actions have provoked only minor reaction from the free and open source software communities for reasons such as fear of the patent holder changing their mind or the license terms being so narrow as to have little use.Companies that have done this include Apple, IBM, Microsoft, Nokia, Novell, Red Hat, and Sun (now Oracle).In 2005 Sun Microsystems announced that they were making a portfolio of 1,600 patents available through a patent license called Common Development and Distribution License.
