Not familiar with this idea, I searched and found this

IIUC, inter partes review is a relatively recent (9 y.o.?) patent law practice that allows 3rd parties to challenge patents directly to the patent office any time between patent award and expiry. I had thought there was only a short period this could be done after award of the patent.

Yeah but it costs 20k

It's more than that. The fee to request the IPR is $19,000, plus $375 for each claim in excess of 20. If the USPTO decides to institute the IPR, the post-institution fee is $22,500, plus $750 for each claim in excess of 20. [0] Attorney's fees will be far more than these amounts.

Funny how Obama pushed this as a good thing for small inventors.

[bdowling]

Right? The AIA made it easier and cheaper (*) for big companies to invalidate the patents of small inventors who try to assert their patents against them. It reduced the amount of money that big companies will pay to license a patent because the threat of an infringement lawsuit became less valuable. It literally took value from small inventors and handed it to big business.

(*) Edit: An IPR may seem expensive (~$500k is average), but if successful it is much cheaper than winning a patent infringement lawsuit ($millions).

It's almost as if Barack Obama had been bought by big tech moguls who didn't like having to pay IP holders for their work but wanted to stop startups from encroaching on their monopolies. Oh wait...
