Counting domestic patents applied internationally

[klsienwe]

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 this? Thus far, I have not used PGFP for fear of losing observations.

The first European patents were granted in 1980, so no national renewal fee records are available before that date. Run this query to see the first granted EP applications:

Code: Select all

SELECT TOP (10) pat_publn_id
      ,publn_auth+publn_nr+publn_kind as number
      ,publn_date, publn_first_grant
FROM tls211_pat_publn
WHERE publn_auth = 'EP' and publn_first_grant = 'Y' 
ORDER BY publn_date asc

Pretty cool and awesome.

The PGFP codes are the easiest proxy to identify whether or not a granted European Patent entered the national phase. (Legally it is a bit more complicated, but PGFP does the job for nearly all different cases.)

I would combine and analyse the differences between the 2 approaches because the quality and coverage of PG25 can (does) differ depending the member state.

what is the best method to determine whether or not the EP has lasped yet/identify whether it is still valid?
