A suggested definition of software patent has been proposed by the Foundation for a Free Information Infrastructure (FFII) as being a "patent on any performance of a computer realised by means of a computer program". There is no legal or conclusive definition for a software patent.
Globally the situation is more complex and reflects varying cultural views of invention itself. Most countries place some limits on the patenting of inventions involving software, but there is no one legal definition of a software patent. For example, U.S. patent law excludes "abstract ideas", and this has been used to refuse some patents involving software. In Europe, "computer programs as such" are excluded from patentability, thus European Patent Office policy is consequently that a program for a computer is not patentable if it does not have the potential to cause a "further technical effect" beyond the inherent technical interactions between hardware and software.
There is a debate over the extent to which software patents should be granted, if at all. Important issues concerning software patents include:
Richard Matthew Stallman (born March 16, 1953), often known by his initials, rms, is a software freedom activist and computer programmer. He campaigns for software to be distributed in a manner such that its users receive the freedoms to use, study, distribute and modify that software. Software that ensures these freedoms is termed free software. Stallman launched the GNU Project, founded the Free Software Foundation, developed the GNU Compiler Collection and GNU Emacs, and wrote the GNU General Public License.
Stallman launched the GNU Project in September 1983 to create a Unix-like computer operating system composed entirely of free software. With this, he also launched the free software movement. He has been the GNU project's lead architect and organizer, and developed a number of pieces of widely used GNU software including, among others, the GNU Compiler Collection, the GNU Debugger and the GNU Emacs text editor. In October 1985 he founded the Free Software Foundation.
