`
`
`Dear Patent Trial and Appeal Board,
`
`
`Petitioner in the above‐referenced proceeding respectfully requests a conference call with the Board to seek
`authorization to file a reply to Patent Owner’s preliminary response pursuant to 37 C.F.R. § 42.108(c).
`
`
`Petitioner seeks leave to file a reply in order to address Patent Owner’s unforeseeable arguments that the Board should
`exercise its discretion to deny institution under 35 U.S.C. § 325(d) based on references not before the Examiner in
`prosecution. See, e.g., Power Integrations, Inc. v. Semiconductor Components Indus., LLC, IPR2018‐01539, Paper 8 at 2
`(PTAB Jan. 7, 2019). Petitioner also seeks to address Patent Owner’s unforeseeable implied construction of
`“exchanging” to require two‐way transmission and to not include “one‐way transmission,” which contradicts the
`definition of “exchange” in the ‘669 Patent’s specification and seeks to construe “exchange” for the first time in any
`proceeding. See ‘669 Patent at 3:18‐20. Finally, Petitioner seeks to address issues associated with Patent Owner’s
`unforeseeable construction of “associated sessions,” first construed in any proceeding by Patent Owner in its
`preliminary response.

`Ericsson v. KPN, IPR2022-00557
`
`
`
`
`
`Petitioner requests 10 pages to address these issues in a reply and 7 days from authorization to file the
`reply. See, e.g., Halliburton Energy Services, Inc. v. U.S. Well Services, Inc., IPR2021‐01032, Paper 8 at 2‐3
`(authorizing preliminary replies of 10‐12 pages to address multiple issues including § 325(d) and claim
`construction).
`
`
`Petitioner does not oppose a sur‐reply from Patent Owner of equal length and limited to the issues raised in the
`reply.
`
`The parties have corresponded regarding this request, and Patent Owner opposes Petitioner’s request to file a reply.
`
`
`Patent Owner submits that Petitioner has not shown good cause to file a reply because Patent Owner’s arguments were
`foreseeable and Petitioner chose to ignore them in the Petition. First, Patent Owner’s arguments regarding § 325(d)
`were foreseeable for at least the reason that the IETF RFC standards asserted in the Petition were cited or described in
`the ETSI TISPAN standards or OMA Service Guide considered by the Office during prosecution. Paper 5, at 15‐17, 29‐
`38. The Petition ignored this explicit cross‐reference between Petition references and references considered by the
`Office. Paper 2, at 7‐8 (addressing § 325(d)).
`
`
`Second, Patent Owner’s arguments that Foti does not teach or suggest “exchanging the composition session identifier at
`least a second time” recited in limitation [1c] are not an “unforeseeable implied construction of ‘exchanging’” as
`asserted by Petitioner. To the contrary, Patent Owner showed that the Petition’s mapping of the 200 OK message in Foti
`to the “exchanging . . . at least a second time” limitation is unsupported by Foti and contrary to RFC 3261. Paper 5, at
`48‐52. Petitioner’s request to rehash the merits of its mapping disguised as “implied [claim] construction” is
`improper. Third, Patent Owner’s proposed construction of “associated sessions” was foreseeable for at least the reason
`that the specification defines the term “associated sessions.” Paper 5, at 26‐27.
`
`
`Patent Owner notes that Petitioner’s request for a 10‐page brief is double the 5 pages allowed for replies. 37 C.F.R. §
`42.24(c); see also Power Integrations, IPR2018‐01539, Paper 8 (5‐page reply). Petitioner has not provided any
`justification for an oversized reply brief.
`
`
`The parties are available for a conference call at the following times (all EDT):
` Tuesday, July 26: 10 am‐11 am or after 1 pm
` Wednesday, July 27: any time
` Thursday, July 28: 12 pm ‐ 3 pm
