  • Rose Parade floats


    Tournament of Roses Parade floats are flower-covered parade floats, used in the annual New Year's Day Tournament of Roses Parade held in Pasadena, California. They evolved from flower-decorated horse carriages and are required to be covered with plant material. Three civic and floral industry leaders judge the floats and award prizes in 24 categories. Some communities and organizational sponsors, such as the City of Burbank, the City of Downey, City of South Pasadena, the City of Sierra Madre, the City of La Cañada Flintridge and the Cal Poly Universities, are referred to as "self-built floats" as they design, construct and decorate their floats solely on volunteer hours; but most are now built by professional float building companies.

  • Taxus baccata


    Taxus baccata is a conifer native to western, central and southern Europe, northwest Africa, northern Iran and southwest Asia. It is the tree originally known as yew, though with other related trees becoming known, it may now be known as common yew, English yew, or European yew.

  • List of prolific inventors


    Thomas Alva Edison was widely known as the America's most prolific inventor, even after his death in 1931. He held a total of 1,093 U.S. patents (1,084 utility patents and 9 design patents). In 2003, he was passed by Japanese inventor Shunpei Yamazaki. On February 26, 2008, Yamazaki was passed by Australian inventor Kia Silverbrook. Yamazaki passed Silverbrook in 2017. Inventors with 200 or more worldwide utility patents are shown in the following table. While in many cases this is the number of utility patents granted by the United States Patent and Trademark Office, it may include utility patents granted by other countries, as noted by the source references for an inventor.

Faris 202 1979-2018 Various This table is usually updated every Tuesday evening in US Eastern time, and is current . The columns are defined as follows: Inventor: The name of the inventor. # of patents: This is the number of utility patents that have been issued. Only utility patents (or the international equivalent) are listed, as a utility patent is a patent for an invention. Not all patents are for inventions. Other patent types include: design patents for the ornamental design of an object; plant patents for plant varieties; and reissue patents, where a correction is made to an already granted patent. This list does not include patent applications (patents pending) as there is no guarantee that a patent application actually describes a novel invention until the patent is granted. Country: This is the country of birth or upbringing of the inventor, where known. If unknown, this is the country of residence identified in the inventor's patent filings. Active: The first and last year in which an inventor received a patent issuance, except when activity was prior to digital records, in which case year of birth (b) and death (d) may be substituted. If an inventor's first year is 1976 or a few years after, there may be activity prior to this; earlier dates are not present in the primary source, and would require a secondary source. Main fields of invention: These are the main areas that the inventor is or was active in.
