On the German Patent offece web site it states this patent has lapsed

German Patent Office link

But are they refering only to the local DE and EP versions or is the WO verison lapsed too ? How do I find out ?

Espacenet only seems to concern the EP version which shows it as lapsed.


  • The WO version is the number of the PCT filing. It does not lapse since it is never, itself, granted. It is no longer operative after the time to enter the national stage in all 140+ PCT countries is past at the 31 month time for most.

    The EP register has a long list of places it has lapsed but I do not know if is everywhere that it was validated or if EPO umbrella patent has lapsed. Besides going into the EPO it also entered the national stage (from the PCT) in Japan and and Poland. patentscope.wipo.int/search/en/… The JP application is shown as withdrawn. Not sure about status in Poland grab.uprp.pl/PropertiesProtection/Site%20pages/….

  • @logikman - WO/PCT is not really a summary of national patents. It is the number of a PCT filing that represents an initial filing in the numerous PCT countries. It could lead to national stages in specific places. One can file in many countries directly without a PCT filing at all or could file a PCT that branches into several countries + other direct filings. Looking at PCT data would not show the direct filings.
