Since I havent had my morning shot I don't quite understand the meaning of SMAN'S post. Does it mean 80% of IPR reviews are granted? Or does it mean when an IPR review is granted then the challenger/infringer wins his challenge on his claim the patent itself is invalid.

If it is the latter does that mean 80% of IPR claims are successful in proving a patent is invalid....That does not sound quite right. 80% of the millions of patents issued by anyone for any reason, when challenged by anyone through an IPR are no good......WOW...I cannot believe that....That's HUGE...
