Patents
Patents are a property right issued by the USPTO to inventors, defined as “the right to exclude others from making, using, offering for sale, or selling” the invention in the U.S. or “importing” it into the U.S. Patents are only applicable within the U.S., its territories and possessions. The USPTO has three years to issue a patent, which usually last 20 years from the date of filing. Once issued, responsibility for enforcing the patent is with the recipient.
There are three types of patents issued by USPTO:
· Utility patents are granted to one who “invents or discovers any new and useful process, machine, article of manufacture, or composition of matter, or any new and useful improvement thereof.”
· Design patents are granted for a “new, original, and ornamental design for an article of manufacture.
· Plant patents “may be granted to anyone who invents or discovers and asexually reproduces any distinct and new variety of plant.”
Other criteria for judging patentability require that it be “novel” and “nonobvious,” and the invention must be described beforehand in enough detail to enable use for its intended purpose.
Patent Laws
Article I, Section 8 of the Constitution gives Congress the power to regulate patent law: “Congress shall have power . . . to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries.” Patent law specifies the subject matter for which patents can be issued and conditions for patentability.
Existing law provides that anyone who “invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent.” In this language “process” is legally defined as “a process, act or method,” including industrial or technical processes. This and the other classes of subject matter provided for (machine, manufacture, composition of matter) together are meant to cover most all man-made things and related processes. A major exception is made for inventions solely intended for “special nuclear material” or atomic weaponry, which are not patentable.
Patent law requires subject matter be “useful,” meaning it has a useful purpose including “operativeness” (an invention must perform its intended purpose in order to be patentable). Further, a complete description of the invention or manufacture is needed to warrant a patent.
Over time, court decisions have determined limits of the field of patentable subject matter, holding that laws of nature, physical phenomena and abstract ideas or not eligible. Raw natural products of nature are not patentable, but DNA and genetic modifications of natural phenomena become patentable when they have been isolated, purified or modified to result in a unique form. Regulations regarding the patenting of gene technology are still extremely controversial and evolving. (See biotechnology in controversy section)
