Re: Identifying patents based on citation from different technological fields

Hello Torben,
your attached pictures suggest that you are looking for 3 groups of cited documents that have no common technological field. Correct ?
Do you have access to PATSTAT Global on a local server ?

Re: Issue with Collecting Patent Data

Hello Wei, the fact that you JOIN your data with the tls212_citation table implies that only cited publications ar retained. Many of them have not been cited, so they will not be included in your data sample. This is the nature of relational data bases. You can avoid this by using a LEFT JOIN, which...

Re: Issue with Collecting Patent Data

Hello Wei, the US application (9848623 - pub 2017-12-26) is available in PATSTAT. Here is the SQL query to retrieve it. SELECT tls201_appln.appln_id , appln_auth , appln_nr , appln_kind , appln_filing_date , appln_nr_epodoc , earliest_filing_date , earliest_publn_date , granted , tls211_pat_publn.pu...

Re: Issue with Collecting Patent Data

Hello Wei, kindly provide some specific examples of granted US patents (2017) that are not available I PATSTAT. The fact whether a patent was cited or not does not affect it to be included in PATSTAT or not. But a patent can not be cited If it is not in the public domain yet - meaning being publishe...

Re: Issue with Collecting Patent Data

Hello Wei, this is not really a "problem", that can be solved. Patents that have been published in 2017 will most probably not have been cited yet. And if they have been cited, the publication will probably not be available to the public. (18 monhts between filing and publication.) So there is simpl...

Re: Issue with Collecting Patent Data

Hello Wei, I see 2 main reasons that could clarify you observation: patents that have a recent earliest_publn_year (limited to BETWEEN 2005 AND 2017) have had less opportunity to be cited then older patents. If a patent has its earliest_publn_year = 2016 (or 2017), it will probably be cited in paten...

Citation Origin PRS: PRe Search

A number of PATSTAT users have asked about citations that have a "PRS" code in the attribute "CITN_ORIGIN" (Origin of citation.) Basically the USPTO examiner produces a sort of search during the examination procedure. This search is independent of the publication rhythm. Once the search is produced,...

Re: Can find some company applicant names from TLS206_PERSON

Hello jsuch, without your SQL query, it is not possible to see what could be wrong on your query. In principle, data available in ESPACENET should be available in PATSTAT, with the exception of data that was added to DOCDB after the data was extracted for the PATSTAT production cycle. (mostly data a...

Re: Patent Citation with PATSTAT

So what does the column "nb_citing_docdb_fam" mean? It is: "Number of distinct DOCDB simple families citing at least one of the publications or applications of the DOCDB simple family of the current application (search report citations from TLS212_CITATION)" You will find this information (and much ...
