According to MPEP 716.04 , “Evidence of a long-felt need may be presented for purposes of rebutting a prima facie case of obviousness.” Long-felt need is particularly valuable when: The need has been recognized and persistent The need has not been satisfied by another before the applicant’s invention The invention actually satisfies the long-felt need Demonstrating these factors can help establish that an invention is not obvious and thus potentially patentable.
