Need Help with International Patents
Posted: Tue Jul 03, 2018 5:32 am
Hi,
I am conducting research on international patents, and trying to find the same patent but different grant date and publication date in different receiving offices.
A situation could be like this, for example : Apple registered a patent under USPTO, but Apple later want the patent to be protected in China, so Apple filed the same patent in China Patent Office.
It is easy to identify Apple Chinese patents, but how could I match the Chinese Apple patents with the American Apple patents, and eventually find out when the same patents are grated respectively in U.S and China?
Is this something PATSTAT can help with?
(PS: Can I find when a patent is grated? it seems that under tls201_appln, there is only filing date and publication date or is publication date here means grant date?)
Many Thanks,
Musso Du
