Re: PATSTAT Global
Hi ,
You are right. Not all legal events in the Category "R" ('PARTY DATA CHANGE') have the fields about old and new party populated. Currently
- 2/3 of the attribute PARTY_OLD and
- 3/4 of the attribute PARTY_NEW are populated.
We provide the data as we receive them from the corresponding patent office and we continuously strive to make the data more complete.
The quality of the office depends on the type of event, the patent authority, the time period and also the type of party (e.g. applicant / owner or legal representative/agent). Therefore it is always recommended to check for each of your analysis whether the data is sufficient for your work.
