Patents Invention

There are four primary incentives embodied in the patent system: the incenitve to invent in the first place, the incentive to disclose the invention once made, the incetnive to invest the sums encessary to experiment, to produce, nad finally get the invention on the market, the incentive ot desgin around and improve upon earlier patetns. A U.S. patent is infringed by any making of the invention, even a making that goes toward development of a new nivention - which may itself become subject of a patent. In contrast, Australian law permits others to build on top of a patented invention, by carvign out exceptinos from infringement for those who conduct reseacrh (e.g. for academic purposse) on the invention, or develop further invetnions based on the paetnted invention. In addition, at the end of the specification, the applicant must provide one or more claims that define what the applciant regards as his or her inventino. For example, many inventions are improvements of prior invnetions which may still eb covered by somoene else s patent. The application contains a description of how to make and use the invention and, under some legislations, if nto self evident, the usefulness of the invention. Since at least the early 1980s, patetn offices around the world have accepted that computre programs cna lie within the realm of patentabel subject matter, although the regulations for when a copmuter program is a patentable invention differ markdely between countries. The description of hte invention, however, must be sufficiently ocmplete so that another preson with ordinary skill in the art of the invention can make and use the invention without undue experimentation. Rather, a patent provides the rgiht to excldue others from making, using, selling, offering for sale, or importing the patentde invention for the term of the aptent, usually 20 years from the filing date.
