Elapsed time until patent decision
Posted: Sat Mar 21, 2020 3:16 pm
Hello everyone,
I am interested in how long the corresponding patent office takes to finally decide upon a patent, thus rejection or grant.
I have written a code for Patstat online and it works. However, it might not yield what I am looking for. Here is the code for patents from German applicants at the German or European Patent Offices in 2010 for example:
The crucial part is the legal status or event code (eventcode#1). For this I rely on the following explanations of the legal status codes:
https://www.epo.org/searching-for-paten ... rs-ep.html
https://www.epo.org/searching-for-paten ... eekly.html
So basically my question is: What legal status code (in Patstat the attribute TLS231_INPADOC_LEGAL_EVENT.EVENT_CODE ) do I have to take into account for
1. rejected patents
2. granted patents
By now I have a bunch of codes which some how refer to...
...rejection: '8131', '8231', '8235', '18R', 'D18R', 'R18R', 'R002', 'R003', 'OHW', 'BHV'
...grant: ('8308', 'V484', 'ZTFE', 'INTG')
However, the results especially on the grant case look not too promising. What codes to I have to take into account to measure the time from filing to final grant decision?
Thanks
Tim
