The protection granted by patents is intended to reward inventors and motivate them to achieve useful and beneficial inventions that will increase the public’s general welfare by their mere availability thereto.
After the Patent term has ended, the invention is passed on to the public domain, so that the public may further enjoy advancements achieved by inventors motivated by the promise of patents. See the Supreme Court’s ruling in Rubinstein , where the court states as follows:
“The purpose of patent protection if to further the development of technology, trade and commerce by
encouraging individuals to invent and publicly show their inventions, based on the incentive – granting an exclusive, monopoly-like right – to exclusively use the invention for a limited time. This right is granted to its owner in return for the full and detailed discovery of the invention for the greater public”.
See also the Supreme Court’s ruling in August Storck , where the court states that:
“One of the main purposes of the monopoly given within Patent Law is the incentive given for inventions, which will become public domain once the patent’s term has ended”.
