`
`Dear Patent Trial and Appeal Board,
`
` I
`
` write on behalf of Petitioners to respectfully request leave to file a short 5-page reply to Patent
`Owner's Preliminary Response ("POPR"). The reply is requested to address POPR Sections IV.A and
`IV.B (related to § 325(d)), IV.C (related to an allegation of extortion) and V.D.2 (related to certain
`secondary considerations).
`
`Patent Owner agrees to Petitioners' reply request and requests a short 5-page sur-reply. Petitioners
`agree to Patent Owner's sur-reply request.
`
`To the extent that the Board is amenable to the foregoing requests, the Parties respectfully propose
`that the reply be due on 1/7 and the sur-reply be due on 1/18.
`
`We appreciate the Board's attention to this matter and happy holidays.

`Respectfully submitted,
