By Eva Lang - Has the Patent Board come up with a new appraisal method? By tallying up how many times a patent is cited in various databases, the Chicago-based Patent Board says it can judge how much a patent is worth.
According to an article titled “A Powerful New Tool for Patent Valuation”  in the March 2008 issue of Business Week the Patent Board's methodology is both simple and enormous. Each patent gets points for how often it is mentioned in patent filings by others as well as by respected publications such as The New England Journal of Medicine. Recent citations also earn higher scores, since these references imply that the idea is closer to technology's cutting edge. The Patent Board charges $10,000 for these “assessments.” - Eva Lang
