Apparently, there was a huge spike of new granted US patents released by the USPTO a few days ago. The reason?
In March 2013, US patent law changed. The ‘first to invent’ became ‘first inventor to file’ for patent protection purposes (see more on this here). As a result, a lot of people rushed to submit applications just before the change. Fast forward 18 months later (last week), a huge spike in USPTO granted patents is observed.
Did SureChEMBL pick that up? See below the cumulative count plot of new patent documents:
And the corresponding compound count extracted from these patents:
