patentunrestricted
Patentunrestricted is a term that describes intellectual property, specifically patents, that are no longer subject to legal restrictions preventing their use or sale. This typically occurs when a patent's term expires, or when the patent holder formally dedicates the invention to the public domain. Once a patent is unrestricted, the invention it covers can be used, manufactured, or sold by anyone without the need for a license or fear of infringement lawsuits from the original patent holder.
The duration of a patent's protection is limited by law, usually for a set number of years
The transition of a patent to an unrestricted status can have significant economic and technological implications.
