资源简介：
The purpose of the bridge file is to assign patent publication numbers of all filings within a family to the respective first filing. The information is derived from PATSTAT tables (PATSTAT spring 2019) TLS201_APPLN, TLS204_APPLN_PRIOR, TLS216_APPLN_CONTN, TLS205_TECH_REL, and TLS211_PAT_PUBLN. First filings can be identified via the variable prior_appln_id in TLS204_APPLN_PRIOR, tech_rel_appln_id in TLS205_TECH_REL, parent_appln_id in TLS216_APPLN_CONTN, and appln_id in TLS201_APPLN (for international applications, internat_appln_id = 0 must hold, see PATSTAT data catalog).
We split the file in order to enable the upload of all information, therefore you find two files below.
The '20200416' files are updated tables that also include an application ID for subsequent filings ("subsequent_appln_id") in addition to the patent number.
