[]

  For the second round of "theme issues", we have chosen the theme of patent value to introduce companies. High technology serves as a source of Japanese companies' competitiveness. In particular, Japanese companies account for at least 20% of all international patent applications in the world and produce innovative and attractive products using patented technology as leverage. How valuable is a company’s patent? We will look at companies from the perspective of "patent value".

Corporate Patent Index System (YK Value)

  YK Value is an indicator which evaluates patent value. The indicator was independently developed by Kudo & Associates.
  A patentee's possession of a monopoly over an invention is a threat from the view of competitors. When an invention is submitted for patent registration, some companies may take it as a hindrance to their business and launch attacks on the patent via legal means, such as seeking to prevent approval of the patent or claiming invalidity after it is registered. YK Value is calculated based on such attacks as an index.The number and severity of attacks reflect the degree of a threat to competitors. This means that the YK Value calculated based on these attacks represents the objective patent value. As such, a company with higher YK Value is considered to hold a “good patent”, and thus, has growth potential.

Selected Companies and their Patented Technology

  Select two companies with high YK Value and undervalued stock prices (whose PER is below average in the sector) listed on the TSE Second Section or Mothers from each of the following sectors: "Chemical", "Machinery", "Information & Communication", "Foods", and "Electric Appliances".
  Please refer to the attachment for the selected companies and their major patented technology.
