`
`
`REQUEST FOR REFUND OF POST-INSTITUTION FEES
`
`On November 7, 2017, Petitioner filed a Petition for post-grant review of
`
`U.S. Patent No. 9,613,186 (“the ’186 patent”) (Paper 1) requesting review of
`
`twenty (20) claims. Petitioner paid a fee of $32,750, including: (i) $12,000 for a
`
`review request fee for up to twenty (20) claims; and (ii) $20,750 for a post-grant
`
`review post-institution fee of twenty (20) claims. On April 4, 2018, the Board
`
`granted the parties’ joint request to terminate the post-grant review of the ’186
`
`Patent prior to the Board’s decision regarding institution. (Paper No. 7). Petitioner
`
`therefore respectfully requests a refund of $20,750 for the post-grant review post-
`
`institution fee under (ii) above.
`
`The Patent and Trial Appeal Board is hereby authorized to charge or refund
`
`any fees associated with this case to Deposit Account 02-1818.
