abstract: Evergreening is any of various legal, business and technological strategies by which producers extend their patents over products that are about to expire, in order to retain royalties from them, by either taking out new patents (for example over associated delivery systems, or new pharmaceutical mixtures), or by buying out, or frustrating competitors, for longer periods of time than would normally be permissible under the law.
