Number of Patents Increase in Missouri, Life Sciences Top List
The number of patents in Missouri increased by 131 last year to 863. The U.S. issued 102,239 patents in 2006. According to the U.S. Patent and Trademark Office (USPTO) this was the first increase in the state in six years. The dip had been gradual until 2005, when the total number of patents dropped to 732, before increasing last year to nearer previous levels.
The USPTO categorizes patents into five categories: utility, design, plant, reissue, and statutory invention registrations (SIR). The most common of patents are utility patents, also known as "patents for inventions" and are responsible for the majority of technological advancement.
Eighty-three percent of last year's patents in Missouri were utility patents. These patents are issued for inventions, such as a new machine, manufacture or composition of matter, or a new and useful improvement. Another 135 patents were categorized as design patents, issued for the design of an article of manufacture; five were issued for an invented or discovered asexually reproduced plants and two were reissued patents.
Between 2001 and 2005 at least one patent was issued for 300 of the 401 (74.8%) classes of patents in Missouri. These came predominantly from life sciences. Four of the top ten classifications were issued in life sciences for the period analyzed: Drug, Bio-Affecting and Body Treating Compositions; Chemistry: Molecular Biology and Microbiology; Organic Compounds; and Multicellular Living Organisms. They accounted for 17.8 percent of all patents issued in Missouri.
