  • Preparing the Rnakings

We have prepared search formulae and rankings by technical field.
Even if a target keyword (software, semiconductor, medicine, etc.) is described in a patent specification, in some cases it is a disclosure as a common example, and it does not substantially contribute to novelty or inventive step.
Thus, as much as possible, we have prepared search formulae that do not include such patents in the population of search results.
This is based on the selection of appropriate search keywords, selection of search sections, and selection of patent classifications.
This reduces the number of noise included in the rankings.  We prioritized noise reduction over coverage.
According to the rankings provided by this site, it is possible to evaluate Patent Firms and Applicants from a technical point of view.
