`Case IPR2015-00158
`Patent 7,296,121 B2
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Patent No. 7,296,121
` IPR2015-00158
`
`Pursuant to 37 C.F.R. § 42.10(e), Sony Corporation, Sony Electronics Inc.,
`
`Sony Mobile Communications AB, and Sony Mobile Communications (USA) Inc.
`
`(collectively, “Petitioners”) hereby move to withdraw Lewis V. Popovski (Reg.
`
`No. 37,423) and Michael Sander (Reg. No. 71,667) as counsel in the Inter Partes
`
`Review of U.S. Patent No. 7,296, 121. Pursuant to 37 C.F.R. § 42.20(b), the Board
`
`has granted authorization for Petitioners to file this motion. Patent Owner does not
`
`oppose this motion.
`
`
`
`Under the Patent Office’s rules, “a practitioner shall not withdraw from
`
`employment until the practitioner has taken reasonable steps to avoid foreseeable
`
`prejudice to the rights of the client, including giving due notice to his or her client,
`
`allowing time for employment of another practitioner, delivering to the client all
`
`papers and property to which the client is entitled, and complying with applicable
`
`laws and rules.” 37 C.F.R. § 10.40(a). Petitioners move to withdraw Mr. Popovski
`
`and Mr. Sander because these individuals are no longer associated with Kenyon &
`
`Kenyon LLP, the firm which represents Petitioners in this action. Kenyon &
`
`Kenyon LLP has retained all relevant papers and property necessary to continue
`
`representation of Petitioners in this action. Furthermore, Petitioners are
`
`concurrently submitting updated mandatory notices pursuant to 37 C.F.R. §
`
`42.8(b)(3) identifying Walter E. Hanley, Jr. (Reg. No. 28,720) as lead counsel and
`
`Zaed M. Billah (Reg. No. 71,218) as back-up counsel. As Petitioners will

`
`Patent No. 7,296,121
`
` IPR2015-00158
`
`
`adequately be represented in this action by other practitioners, Petitioners will not
`
`be prejudiced by the withdrawal of Mr. Popovski and Mr. Sander.
`
`Respectfully submitted,
