Search for patents with no ipc
Posted: Sun May 12, 2019 1:59 pm
Dear support,
is there a way to search for patents like CA182819 (S), which do not have any classifications?
Of course I could search for title, abstract and other parameters.
But my problem is that I don't know those. I usually search for ipc and nothing else and because some patents don't have any classifications is there another way to find them? Maybe to specifically search for patents without any classifcations?
Best regards,
jpatent
