The Japanese commissioner in Washington DC in the 1900's studying the American patent system said, "We have looked about us to see what nations are the greatest, so that we can be like them... We said, 'What makes the United States such a great nation?' and we investigated and found that it was patents, and we will have patents."

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."

A plant patent covers asexually reproducible plants (that is, through the use of grafts and cuttings), such as flowers. Sexually reproducible plants (that is, those that use pollination), can be monopolized under the Plant Protection Act. Both sexually and asexually reproducible plants can now also be monopolized by utility patent. Plant patents are comparatively recent innovations, the first one being granted in 1930. A plant patent is granted by the Government to an inventor (or the inventor's heirs or assigns) who has invented or discovered and asexually reproduced a distinct and new variety of plant, other than a tuber propagated plant or a plant found in an uncultivated state. The grant, which lasts for 20 years from the date of filing the application, protects the inventor's right to exclude others from asexually reproducing, selling, or using the plant so reproduced. This protection is limited to a plant in its ordinary meaning: (1) A living plant organism which expresses a set of characteristics determined by its single, genetic makeup or genotype, which can be duplicated through asexual reproduction, but which can not otherwise be "made" or "manufactured." (2) Sports, mutants, hybrids, and transformed plants are comprehended; sports or mutants may be spontaneous or induced. Hybrids may be natural, from a planned breeding program, or somatic in source. While natural plant mutants might have naturally occurred, they must have been discovered in a cultivated area. (3) Algae and macro fungi are regarded as plants, but bacteria are not. A utility patent would be filed for claims to plants, seeds, genes, etc. According to the USPTO, there were 959 plant patent applications filed in 2009.
