Can anyone recommend a database that contains information regarding
foreign patents that were issued before 1963? I need to obtain family
history information on two German patents that Derwent and Inpadoc do
not cover. (one was issued in 1960 the other in 1962)
How does one go about finding out family histories of old patents? Are
there other avenues besides Derwent and Inpadoc?
Thanks
Louise
