`IPR2018-00405
`
`Pursuant to 37 C.F.R. § 42.10(e), Patent Owner respectfully requests that the
`
`Board authorize the withdrawal of David A. Casimir and Mary Ann Brow as its
`
`counsel. The Board authorized the filing of this motion in its email of March 20,
`
`2018.
`
`Upon grant of this motion, Patent Owner will promptly file Amended Patent
`
`Owner’s Mandatory Notices and a Substitute Power of Attorney appointing Aaron
`
`F. Barkoff and Christopher P. Singer of McAndrews, Held & Malloy, Ltd. as its
`
`lead and back-up counsel, respectively. Mr. Barkoff and Mr. Singer are USPTO-
`
`registered attorneys.
`
`In identifying substitute counsel, reasonable steps have been taken to avoid
`
`foreseeable prejudice to Patent Owner, in accordance with 37 C.F.R. § 10.40(a).
`
`Further, Patent Owner confirms that it will not seek any extensions of time due to
`
`the substitution of counsel or otherwise.
`
`Petitioner has stated that it does not oppose this motion.
