a method of calculating a remaining cited-patent life time, an apparatus for calculating a remaining cited-patent life time, and storage medium for storing a program calculating a remaining cited-patent life time

摘要

The present invention relates to a remaining technology life calculation method, a remaining technology life calculation device, and a storage medium for a program capable of calculating a remaining technology life. One embodiment of the present invention is a method for calculating patent quotations by calculating the number of citations cited according to the elapsed years of the patents from the information of the patents of the first technology group, Calculating a star survival probability, calculating an average quoted patent life span including the obsolescence period of the patents using the calculated survival probabilities by the number of years elapsed, and calculating a first cited patent lifetime including the first patent Calculating a remaining life expectancy of the first patent by subtracting the elapsed years of the first patent from the calculated average quoted patent life span.
