Inter Partes Review: An Early Look at the Numbers

Los Altos, CA, October 22, 2014 – Inter Partes Reviews (IPRs) are resolved 60% faster than Inter Partes re-examinations and they are twice as likely to find reviewed patents invalid.

This is among the findings in an article written by Santa Clara University College of Law Assistant Professor Brian Love and Unified Patents Chief Operating Officer, Shawn Ambwani. The paper will be published by the University of Chicago Law Review. With regard to IPR timing:

– The 160 final determinations (final written decisions and requests for adverse judgment) had an average pendency of 15 months vs. a 36-month average for IPX.

– The average time to termination was roughly 9 months among the 979 petitions that fell within our study window and settlements averaged about 7 months.

"The paper reveals just how fundamentally patent review procedures have changed since the adoption of the America Invents Act was," said Shawn Ambwani, Unified Patents COO and co-author of the Chicago article. Over the past 20 months since they were instituted, IPRs invalidated all challenge claims at over twice the rate of re-examinations. Motions to stay litigation are 80% higher with IPRs.
