Hello again, I wanted to disaggregate regional applications (i.e. those made to the EP or EA) so that I can identify the individual countries in which a particular application is enforced. I have disaggregated applications made to the EP and EA by, using TLS201 as the starting dataset: 1) merging th...

Hi again, I am still yet to hear a response regarding how I can identify regional applications (i.e. situations in which appln_auth = EP, for example) enforced nationally (i.e. which EP countries the application is designated to) in the years prior to 1980 (i.e. before PGFP was used). How can I do t...

Hello, I wanted to use data on the country of origin for the inventors associated with certain patents and found that there were many missing values. I tried to find help from the forum regarding this, and the last time this problem was addressed was in 2014 and the solution was a missing data imput...

Hello, I am a bit confused about how the PCT route and international patents relate, and how to intepret applications to the EP in the patstat data. 1) From my understanding, an application throug the PCT route imply the application is "valid in all Contracting States of the PCT". Who does...

Hello again, When I tried using the PGFP variable as a means of detecting patent enforcement, I find that the range of years which in which such payments were made for the particular kind of patent I am interested in ranges from 1981-2017. This implies that prior to 1981, there were no patents being...

Another question: While the PGFP variable is the best proxy for whether an EP was enforced within a particular country, what is the best method to determine whether or not the EP has lasped yet/identify whether it is still valid?

Thank you for the prompt reply. 1) I think I made a typo when I used the word "investor". I meant inventor, apologies. 2) in refence to the question in your reply " Would you consider a German inventor filing and EP application as being "domestic" ?". My intention is to...

Hello, I wanted to ask for help countring the number of patents which came from a domestic inventor but have been applied overseas. I am wary of interpreting this to be the meaning of the appln_auth variable, as I fear it may the case that simply applying for a patent from a particular authority doe...
