`
`
`I. INTRODUCTION
`We instituted inter partes review of U.S. Patent No. 7,848,439 B2
`(Ex. 1001, “the ’439 patent” or “the challenged patent”)2 in two
`proceedings—IPR2018-01555 (“IPR1555”) and IPR2018-01581
`(“IPR1581”) —based on petitions filed by the same petitioner (HTC
`Corporation and HTC America, Inc., collectively “Petitioner”).
`(“IPR1581”). See IPR1555, Paper 8 (“IPR1555 Dec.”), Paper 10; IPR1581,
`Paper 93 (“IPR1581 Dec.”). The challenged patent is owned by INVT SPE
`LLC (“Patent Owner”).
`In IPR1555, we instituted review of claims 1–7 of the ’439 patent on
`March 7, 2019 and, in a scheduling order issued the same day, we set an oral
`hearing for December 17, 2019 (among other due dates). See generally
`IPR1555 Dec.; IPR1555 Paper 9 (Scheduling Order). In IPR1581, we
`instituted review of independent claim 8 of the ’439 patent on April 1, 2019
`and, in a scheduling order issued the same day, we set an oral hearing for
`January 8, 2019 (among other due dates). See generally IPR1581 Dec.;
`IPR1555 Paper 10 (Scheduling Order).
`
`
`2 The challenged patent is Exhibit 1001 in both IPR1555 and IPR1581.
`3 An error occurred during initial uploading of the Decision to Institute and
`Scheduling Order to the PTAB End-to-End information technology system
`(PTAB E2E). Papers 7 and 8 were created in PTAB E2E and then
`immediately expunged. The Decision to Institute and Scheduling Order then
`were uploaded a second time to PTAB E2E as Papers 9 and 10, respectively.
`As a result, the respective caption pages of the Decision to Institute and the
`Scheduling Order each indicate incorrect paper numbers (Papers 7 and 8),
`rather than the correct paper numbers (Paper 9 and 10).

`
`II. THE CHALLENGES
`The challenges brought by Petitioner in IPR1555 and IPR1581 have
`substantial similarities. The independent claims challenged in each
`proceeding have many identical limitations, as illustrated in the following
`chart that italicizes the limitations that are identical.
`Claim 1 (Challenged in IPR1555)
`Claim 8 (Challenged in IPR1581)

`channel estimation per subband;
`a channel estimation per subband;

`assigned to the subband group.
`
`
`See Ex. 1001, 12:65–13:27 (claim 1), 13:65–14:26 (claim 8).

`Patent 7,848,439 B2
`
`
`Furthermore, Petitioner applies the following prior art4 in each
`proceeding:
`U.S. Patent No. 6,904,283 B2, filed April 17, 2001, issued June
`7, 2005 (Ex. 1003, “Li”);
`U.S. Patent No. 7,221,680 B2, filed September 1, 2004, issued
`May 22, 2007 (Ex. 1004, “Vijayan”); and
`U.S. Patent No. 6,721,569 B1, filed September 29, 2000, issued
`April 13, 2004 (Ex. 1005, “Hashem”).
`In IPR1581, Petitioner also asserts the following reference:
`U.S. Patent No. 5,596,604, filed August 17, 1993, issued
`January 21, 1997 (Ex. 1006, “Cioffi”).
`More particularly, the asserted ground at issue in IPR1555 is whether
`claims 1–7 are unpatentable as obvious under 35 U.S.C. § 103 over Li,
`Vijayan, and Hashem. The asserted ground at issue in IPR1581 is whether
`independent claim 8 of the ’439 patent as unpatentable under 35 U.S.C.
`§ 103 over Li, Vijayan, Hashem, and Cioffi. IPR1581 Dec. 7–8.
`In IPR1581, Petitioner cites to Cioffi as teaching using weighting per
`subchannel in combination with the cluster groups taught by Li and subband
`groups taught by Vijayan as teaching or suggesting limitation the wherein
`limitation recited in independent claim 8 but not recited in independent
`claim 1: “wherein the parameter deciding section decides the coding
`parameters in such a manner that a number of information bits obtained by
`assigning a weight per subband group to a sum of information bits that are
`able to be assigned to all of the subbands within the subband group, is
`assigned to the subband group.” IPR1581 Dec. 36 (citing Pet. 30).

`
`
`Petitioner also relies on declaration testimony by Dr. Zhi Ding
`(Exhibit 10075) in both IPR1555 and IPR1581.
`As noted in our Scheduling Order issued in IPR1581 (Paper 10),
`Patent Owner has the option to receive preliminary guidance from the Board
`on a motion to amend filed in that proceeding. See Notice Regarding a New
`Pilot Program Concerning Motion to Amend Practice and Procedures in
`Trial Proceedings under the America Invents Act before the Patent Trial and
`Appeal Board, 84 Fed. Reg. 9497 (Mar. 15, 2019) (“MTA Pilot Program
`Notice”). In that Scheduling Order, we referred the parties to the Board’s
`Guidance on Motions to Amend in view of Aqua Products
`(https://go.usa.gov/xU6YV), and Lectrosonics, Inc. v. Zaxcom, Inc., Case
`IPR2018-01129 (Paper 15) (PTAB Feb. 25, 2019) (precedential). The MTA
`Pilot Program Notice does not automatically apply to IPR1555.
`
`III. DISCUSSION
`A conference call between the parties and the panel will be held on
`Wednesday, April 10, 2019 commencing at 2:30 pm Eastern Time. Prior
`to the call, the parties should meet and confer regarding ways in which these
`two inter partes reviews can be consolidated or otherwise conducted in light
`of the significant overlap of the proceedings. Such proposals by the parties
`should explicitly consider how Motions to Amend filed are to be handled in
`any consolidated proceeding. The parties should come prepared to discuss
`their proposals with the panel.
`It is so ORDERED.
