PTAB Average Time-To-Decision in IPRs May Surprise You

This post was co-authored by Foley & Lardner Summer Associate Jonathan E. Robe.

Ever wonder how long it takes the PTAB to decide to institute trial? Ever have someone ask how long it will take for the Board to issue its final written decision?

Of course, the maximum amount of time is fixed – 3 months to an institution decision and 12 months to a final decision. But an analysis of 100 recent PTAB decisions reveals that the actual amount of time could be just 1 month and 9 months, respectively.

The data sets consisted of 100 IPR proceedings which reached a final decision on the merits through May 31, 2015.¹

Time to Institution Decision

The first data set evaluated the amount of time from the patent owner’s preliminary response to the PTAB’s decision to institute trial. Table 1 provides some summary statistics.

Time to Final Decision

The second data set evaluated the time from the PTAB’s decision to institute until its final written decision. For ease of calculation, it was assumed that each month of the year had exactly 30 days. Thus, those proceedings in which the time interval between institution decision and final decision was 364 days are expressed in these results as 12.13 months. Table 2 provides some summary statistics for this set.

Conclusion

Surprisingly, some institution decisions have come as swiftly as one month after the patent owner’s preliminary response and more than 10% of the institution decisions studied were issued by the 2 month mark. As for the final written decisions, fully 16% were issued by 11 months from institution, with some coming just over 9 months from institution.
