The graph below shows the number of B1 publications (grants) from the beginning up to 15th June of the stated years 2008-2016. As can be seen, these have been in the region 21,000 to 30,000 from 2008-2015, but increase dramatically (to over 41,750) in 2016. This looks like a hockey stick graph to me.
Applying some rough and ready guesswork, one can guess a total number of patents granted in 2016 as in the region 88,000 to 102,000 representing an increase of 29-49% in the number of grants over 2015.
What is happening in the background that explains this sudden increase?
