`Inter Partes Review of U.S. Patent No. 8,891,347
`
`T-Mobile USA, Inc., AT&T Services Inc., AT&T Mobility LLC, AT&T
`
`Corporation, Cellco Partnership d/b/a Verizon Wireless, Nokia of America
`
`Corporation, and Ericsson Inc., (“Petitioners”) petition for inter partes review of
`
`Claims 1-4, 6-12, 14-17, and 19-23 (“Challenged Claims”) of U.S. Patent No.
`
`8,891,347 (“’347 Patent”).
`
`I.
`
`INTRODUCTION
`The ’347 Patent is directed to a technique for predistorting signals at a
`
`transmitter (e.g., a base station or eNodeB) based on channel estimation feedback
`
`provided by a receiver (e.g., a user equipment (“UE”)). According to the ’347 Patent,
`
`this predistortion must occur in the in a time-domain, a frequency-domain, and a
`
`spatial-domain. In the co-pending district court litigations, Patent Owner has
`
`identified the alleged infringing products as 5G cellular products capable of
`
`beamforming a wireless signal.
`
`The problem with the ’347 Patent and Patent Owner’s allegations is that
`
`beamforming in a time-domain, a frequency-domain, and a spatial-domain was part
`
`of the prior art 4G standard, and numerous textbooks have been written describing
`
`the channel estimation and beamforming capabilities of LTE. One example is Sesia
`
`et al., “LTE: The UMTS Long Term Evolution from Theory to Practice” (“Sesia”).
`
`Thus, as described in detail below, the Challenged Claims are unpatentable
`
`over Sesia in view of the Patent Owner’s apparent interpretation of the claims.

`
`grounds of challenge include:

`
`Ground ’347 Patent Claims
`
`Basis for Ground
`
`1
`
`1-4, 6-12, 14-17,
`
`Sesia et al., “LTE: The UMTS Long Term
`
`19-23
`
`Evolution from Theory to Practice,” (“Sesia,”
`
`Ex. 1003) under 35 U.S.C. § 103
`
`As stated on the face of the patent, the earliest priority date of the ‘347 patent
`
`is July 28, 2011. Sesia is prior art to this patent for the reasons stated below.
`
`Sesia (Ex. 1003): Sesia was published by John Wiley & Sons, Inc. (“Wiley”)
`
`in its “Wiley Online Library” on July 22, 2011. Exhibit 1003 is a true and correct
`
`copy of Sesia and has been compared to the eBook version of Sesia available online
`
`through the “Wiley Online Library.” Ex. 1004, ¶16. As set forth in Dr. Hall-Ellis’s
`
`declaration, the “Wiley Online Library” states that Sesia was “First published” on
`
`July 22, 2011. Ex. 1004, ¶18. Wiley is a well-respected and reputable academic
`
`publisher that was established in 1807 and has published millions of scholarly
`
`publications. Id. Sesia also bears a copyright date of 2011 and includes catalog
`
`information (such as catalog number, ISBN, and ISSN), which are established
`
`markers of a printed publication. Id.; see Hulu, LLC, v. Sound View Innovations,
`
`LLC, IPR2018-01039, Paper 29, at 19 (Dec. 20, 2019) (precedential).
`
`Petitioners’ expert Mr. Proctor also testifies that he is familiar with the website
`
`publication practices of Wiley, including that the “First published” date listed on the
`
`Wiley Online Library website is, to a POSITA, a reliable date indicative of its
`
`6
`
`

`

`Inter Partes Review of U.S. Patent No. 8,891,347
`
`publication status. Ex. 1005, ¶69. Wiley is a “well-known, reputable compiler and
`
`publisher of scientific and technical publications, and . . . members in the scientific
`
`and technical communities who both publish and engage in research rely on
`
`information published on” Wiley’s website. Ex. 1005, ¶69; see also Ericsson Inc.
`
`v. Intellectual Ventures I LLC, IPR2014-00527, Paper 41 at 11 (May 18, 2015)
`
`(taking “Official Notice” with respect to IEEE, a publisher with a similar reputation
`
`as Wiley); Google LLC v. Vocalife LLC, IPR2022-00005, Paper 10 at 21 (Apr. 15,
`
`2022) (holding that reference is a printed publication based on indicia on the face of
`
`the reference because Wiley is an “established publisher”).
`
`Further evidence corroborates that Sesia was published on July 22, 2011, and
`
`that Exhibit 1003 is an authentic copy of Sesia as first published. First, the metadata
`
`for Exhibit 1003 states that the document was created on July 13, 2011, and that the
`
`date of the metadata is July 19, 2011, as shown in the “xmp:CreateDate” and
`
`“xmp:MetadataDate” from the screenshot below. Ex. 1004, ¶19.

`
`Second, the “Wiley Online Library” states that Sesia’s Digital Object
`
`Identifier (DOI) is 10.1002/9780470978504, which when entered into doi.org
`
`redirects to the Wiley Online Library’s webpage for Sesia. A DOI is an identifier
`
`defined by ISO 26324 used for identifying documents, especially academic papers.
`
`Ex. 1004, ¶20. The DOI system is managed by the well-known non-profit
`
`International DOI Foundation, whose website is www.doi.org, which allows any
`
`member of the public to enter a DOI identifier to retrieve the object (usually a
`
`website URL) attached to the identifier. Id. A DOI can be registered using a third-
`
`party registration agency. Id. Sesia’s DOI was registered with CrossRef, a non-profit
`
`organization that allows members to “create metadata records that identify, describe,
`
`and locate their work.” Id. (quoting https://www.crossref.org/membership/).
`
`According to CrossRef, Sesia’s DOI is for an “EDITED BOOK published 22 July
`
`2011.” Id. (quoting https://search.crossref.org/?from_ui=yes&q=10.1002%2F97804
`
`70978504). This further corroborates that Sesia was publicly available on July 22,
`
`2011. Id.
`
`Sesia thus was available to “persons interested and ordinarily skilled in the
`
`subject matter or art[,] exercising reasonable diligence.” See Voter Verified, Inc. v.
`
`Premier Election Sols., Inc., 698 F.3d 1374, 1380 (Fed. Cir. 2012) (quoting SRI Int’l,
`
`Inc. v. Internet Sec. Sys., Inc., 511 F.3d 1186, 1194 (Fed. Cir. 2008)); Jazz Pharm.,
`
`Inc. v. Amneal Pharm., Inc., 895 F.3d 1347, 1356 (Fed. Cir. 2018); see also MPEP

`
`§ 2128. Thus, Sesia qualifies as prior art under at least 35 U.S.C. § 102(a) (pre-AIA)
`
`as a printed publication which was published July 22, 2011. Ex. 1004, ¶¶17-22.
`
`VII. BACKGROUND
`A.
`Person of Ordinary Skill in the Art
`A POSITA at the time of the alleged invention of the ’347 Patent would have
`
`had at least a bachelor’s degree in electrical engineering, computer engineering,
`
`computer science, physics, or the equivalent, and at least two years of experience
`
`working in the field. Ex. 1005, ¶41. Relevant working experience would include
`
`experience with cellular telecommunications and networking, radio-access network
`
`architectures, protocols, and signal propagation in wireless networks. Id. More
`
`education can supplement practical experience and vice versa. Id.

`
`The ’347 Patent
`1.
`Description of the ’347 Patent’s Specification
`The ’347 Patent describes a pre-distortion technique for transmitting signals
`
`from a transmitter (e.g., a base station or eNodeB) to a receiver (e.g., UE) in a
`
`wireless communication system such as a Long-Term-Evolution (LTE) or LTE-
`
`Advanced communication system. See Ex. 1001, 12:54-58; Ex. 1005, ¶42.
`
`Figure 1 of the ’347 Patent illustrates a simplified overview of a wireless
`
`communications system that comprises multiple propagation paths—the lines
`
`labeled 170, 175, and 180 (illustrated in green, orange, and blue below)—between
`
`the transmitter (110) and the receiver (150). Ex. 1001, 3:23-26, Fig. 1; Ex. 1005,
`
`9
`
`

`

`Inter Partes Review of U.S. Patent No. 8,891,347
`
`¶45, Fig. A. These propagation paths are the routes that signals may travel from the
`
`transmitter to the receiver. Ex. 1001, 7:38-49; Ex. 1005, ¶45. The ’347 Patent
`
`explains that there are multiple propagation paths due to signals scattering,
