Abstract

<p>In order to write a specification that seemed to be a new invention, or to confirm that it is the most advanced technology that has not existed before, it is effective to conduct a patent search for existing inventions to determine whether or not there are any similar patents in the technical field and what they contain. Many organizations and departments have published books or held seminars on the methods and points to keep in mind when conducting a Japanese patent search, including the concept of creating a search strategy and the selection of patent classifications and keywords. However, most of them are based on the author’s or lecturer’s experience as to which items should be surveyed, and no evidence-based explanation seems to have been provided. This paper presents the results of a survey on the frequency of occurrence of non-essential items in specification by gazette type and by year of application (2013, 2016, and 2019) for about 34,000 patents in the field related to polymeric materials. I hope that the data in this paper will provide hints for those who conduct patent searches in related technical fields in creating search strategy.</p>
