본 논문은 “한국 특허 데이터 프로젝트(Korea Patent Data Project, KoPDP)”의 내용과 방법에 대해 소개한다. KoPDP는 1948-2016년 동안 한국 특허청에 출원된 모든(실용)특허와 1976-2016년 사이 한국에 위치한 출원인 및 발명자가 미국 특허청에출원․등록한 모든 특허에 대한 자료를 수집하고, 출원인-기업명 매칭(matching)을통해 각종 기업 관련 정보를 제공하는 DataGuide 5.0과 연결하였다. 그 결과14,803개의 상장 및 비상장 한국 기업의 재무 및 금융 정보를 비롯하여 해당 기업이한국과 미국에서 출원․등록한 특허 정보에 대한 포괄적인 데이터베이스를 구축하였다. 한국 특허의 경우 전체 표본 특허의 45% 이상이, 미국 특허의 경우 제1 출원인이 한국인 표본 특허의 약 87%가 한국 기업 정보와 연결되었다. 본 논문은 출원인-기업명 매칭 과정에 대한 자세한 설명과 함께 한국과 미국 특허 간에 일관된 산업 분류체계를 제공한다.
Abstract
In this paper, we describe the contents and methods of “Korea Patent Data Project (KoPDP)”. The project collects all utility patents granted from the Korea Intellectual Property Office (KIPO) for the period 1948-2016 and the US Patent and Trademark Office (USPTO) for the period 1976-2017. The project also matches their assignees to firms in DataGuide 5.0, a Korean financial database. The resulting dataset includes total 14,803 listed and non-listed Korean firms matched with their Korean and US patents, in addition to a host of accounting and financial information. Over 45% of all sample KIPO patents and 87% of US patents assigned to Korean assignees are matched. We explain the detail of our matching procedures and also provide a coherent industry classification system for both sets of patents.
