Patents to plants which are stable and reproduced by asexual reproduction, and not a potato or other edible tuber reproduced plant, are provided for by Title 35 United States Code, Section 161 which states: Whoever invents or discovers and asexually reproduces any distinct and new variety of plant, including cultivated sports, mutants, hybrids, and newly found seedlings, other than a tuber propagated plant or a plant found in an uncultivated state, may obtain a patent therefor, subject to the conditions and requirements of title. (Amended September 3, 1954, 68 Stat. 1190). The plant patent must also satisfy the general requirements of patentability. The subject matter of the application would be a plant which developed or discovered by applicant, and which has been found stable by asexual reproduction. To be patentable, it would also be required: (1) That the plant was invented or discovered and, if discovered, that the discovery was made in a cultivated area. (2)That the plant is not a plant which is excluded by statute, where the part of the plant used for asexual reproduction is not a tuber food part, as with potato or Jerusalem artichoke. (3) That the person or persons filing the application are those who actually invented the claimed plant; i.e., discovered or developed and identified or isolated the plant, and asexually reproduced the plant. (4) That the plant has not been sold or released in the United States of America more than one year prior to the date of the application. (5)That the plant has not been enabled to the public, i.e., by description in a printed publication in this country more than one year before the application for patent with an offer to sale; or by release or sale of the plant more than one year prior to application for patent. (6) That the plant be shown to differ from known, related plants by at least one distinguishing characteristic, which is more than a difference caused by growing conditions or fertility levels, etc. (7) The invention would not have been obvious to one skilled in the art at the time of invention by applicant.

The main type of patent, a utility patent, covers inventions that function in a unique manner to produce a utilitarian result. Examples of utility inventions are Velcro® hook-and-loop fasteners, new drugs, electronic circuits, software that is tied to some form of hardware, semiconductor manufacturing processes, new bacteria, newly discovered genes, new animals, plants, automatic transmissions, Internet techniques and methods of doing business (provided physical things are involved), and virtually anything else under the sun that can be made by humans. To get a utility patent, one must file a patent application that consists of a detailed description telling how to make and use the invention, together with claims (formally written sentence fragments) that define the invention, drawings of the invention, formal paperwork, and a filing fee. Sometimes the state of the art, rather than the nature of the novelty, will determine whether a design or utility patent is proper for an invention. If a new feature of a device performs a novel function, than a utility patent is proper. According to the USPTO in 2009, there were 456,106 utility patent applications. Patent law is designed to promote innovation in "science and useful arts." It's right there in the first Article of the Constitution: in order to be patentable, an invention needs to be useful in some way. Utility patents expire 20 years from the date of filing.

In Article I, Section 8 of the Constitution of the United States it says, " Congress shall have power [...] to promote the progress of science and useful arts by securing for limited times to inventors the exclusive right to their respective discoveries."

Although most inventions will be concerned with the rights a patent grants during its monopoly or in-force period (from the date the patent issues until it expires (20 years after the filing date)), the law actually recognizes five "rights" periods in the life of an invention. (1) Invention conceived but not yet documented: When an inventor conceives of an invention, but hasn't yet made any written, signed, dated, and witness record of it, the inventor has no legal rights whatsoever, only the potential for acquiring rights. (2) Invention documented but patent application not yet filed: After making a proper, signed, dated and witnessed documentation of an invention, the inventor has valuable rights against any inventor who later conceives of the same invention and applies for a patent. An inventor who documents the building and testing of the invention has substantially greater rights than one who merely documents conception. During this period the invention may also be treated as a "trade secret" this is, kept confidential. This gives the inventor the legal right to sue and recover damages against anyone who immorally learns of the invention, for instance, through industrial spying. (3) Patent Pending - Patent application filed but not yet issued: During the patent pending period, including the one year period after a provisional patent application is filed, the inventor's rights are the same as they are in period 2 above for the most part. Otherwise, the inventor has no rights whatsoever against infringers, only the hope of a future monopoly, which doesn't commence until a patent issues. Most companies that manufacture a product this is the subject of a pending patent application will mark the product "patent pending" in order to warn potential copiers that it they copy the product, they may have to stop later if and when the patent issues. The PTO by law must keep all patent applications preserved in secrecy until the application is published or the patent issues. The patent pending period usually lasts from one to three years. (4) In-force patent - patent issued but hasn't yet expired: After the patent issues, the patent owner can bring and maintain a lawsuit for a patent infringement against anyone who makes, uses or sells the invention without permission. The patents in force period last from the date it issues until 20 years from its filing date, provided maintenance fees are paid. Nearly every patent is guaranteed an in-force period of at least 17 years. In order to assure this 17-year term, the patent will be extended, if necessary, to compensate for delays resulting from failures by the PRO in processing the patent application. Also, once the patent issues, it becomes a public record or publication that can block others who file later from getting patents on the same or similar inventions, that is, it becomes "prior art" to anyone who files after its filing date. (5) Patent expired: After the patent expires (20 years after the filing date, or sooner if a maintenance fee isn't paid), the patent owner has no further rights, although infringement suits can be brought for any infringement that occurred during the patent's in-force period. An expired patent remains a valid "prior art reference" (as of its filing date) forever. IPStreet.com's patent search tools and resources will help you better understand if your idea is patentable, the duration of a patent and complex patent analytics.

Essential to understanding your portfolio, is to understand changes in your portfolio over time. Beyond merely counting the size of your portfolio as patents are granted and expired, you also need to consider other accumulation and growth patterns: velocity, momentum, claim quality, claim scope, geographic coverage (international), patent duration, patent analytics and patent fences or thickets. Using our patent search tools, such analyses are easy to do. Let IPstreet.com help you today.
