doctrine of equivalents in relation to Invention and Patent Law
A doctrine which says that even if a patent claim does not literally read on a possibly infringing device, it can be read more broadly providing it does not read on the prior art. It is designed to allow the inventor to assert a patent where the differences between the inventor’s and an infringer’s product are not substantial. (See Hilton Davis Chemical Company v. Warner-Jenkinson Company, Inc. 93-1088)
