`U.S. Patent No. 8,942,107
`
`
`
`I. INTRODUCTION AND SUMMARY OF ARGUMENTS
`
`Petitioner contends the ’107 Patent is obvious in view of the De Nicolo
`
`references—the ’468 and ’666 Patents—each of which was before the examiner
`
`during prosecution of the ’107 Patent.1 Both of the De Nicolo references are
`
`directed to providing operating powering to devices. For at least the following
`
`reasons, Petitioner has failed to show that the claims at issue are invalid as obvious
`
`in view of the De Nicolo references.
`
`First, the De Nicolo references are not prior art to the ’107 Patent. The
`
`inventors of the ’107 Patent conceived their invention before the priority dates of
`
`the De Nicolo references and diligently reduced it to practice.
`
`Second, the De Nicolo references are not directed to the subject matter
`
`disclosed in the ’107 Patent—i.e., a system for managing multiple remote assets in
`
`a network, even when the assets are without operating power—and Petitioner has
`
`not provided a basis for assuming that a person of ordinary skill would have been
`
`motivated to combine them to create such a system.
`
`
`1 Specifically, Petitioner challenges the following claims: independent claim 1
`
`and its dependent claims 31, 37, 58, 59, 69, 72; and independent claim 73 and its
`
`dependent claims 106, 112, 134, 142, 145.
`
`– 1 –
`
`
`
`Case No. IPR2016-00569
`U.S. Patent No. 8,942,107
`
`Third, a person of ordinary skill would not have been motivated to combine
`
`the De Nicolo references to solve the hypothetical problem posed by Petitioner—
`
`i.e., finding a way to selectively power an Ethernet device based on its maximum
`
`power requirement.
`
`Fourth, Petitioner has not shown that its proposed combination would have
`
`had a reasonable expectation of success.
`
`Fifth, the combined De Nicolo references do not meet or disclose many of the
`
`limitations of the claims at issue.
`
`Accordingly, the Board should reject Petitioner’s arguments and refuse to find
`
`the claims at issue unpatentable.
`
`
`
`II. BACKGROUND
`
`A. Status of Related Litigation
`
`The ’107 Patent is one of four related patents asserted against Petitioner in
`
`litigation pending in the Eastern District of Texas, which is set for a jury trial on
`
`January 3, 2017.2 The ’107 Patent is also asserted against Alcatel–Lucent
`
`Enterprise USA Inc. (“ALE”) in litigation pending in the Eastern District of
`

`
`Texas.3 A jury trial was held against ALE the week of October 3, 2016, resulting in
`
`a jury verdict in favor of Chrimar. The ’107 Patent is also asserted in four cases
`
`pending in the Northern District of California, all four of which are currently
`
`stayed.4 The ’107 Patent is also the subject of two other petitions for Inter Partes
`
`Review.5 The court in the Eastern District of Texas construed certain terms of the
`
`’107 Patent.
`
`B. The ’107 Patent
`
`The ’107 Patent is directed to methods and systems for managing devices
`
`connected in a star-wired Ethernet network. The claims “relate[] generally to
`
`computer networks and, more particularly, to a network management and security
`
`system for managing, tracking, and identifying remotely located electronic

`
`equipment on a network.”6 The “invention is particularly adapted to be used with
`
`an existing Ethernet communications link or equivalents thereof.”7
`
`More specifically, the patent discloses identifying an “asset,” such as a
`
`computer, “by attaching an external or internal device to the asset and
`
`communicating with that device using existing network wiring or cabling.”8 The
`
`remote device is referred to as a “remote module.”9 An asset can be managed,
`
`tracked, or identified by using the remote module to communicate information
`
`about the asset to network monitoring equipment, referred to as a “central
`
`module.”10
`
`The basic configuration of an embodiment of the system claimed by the patent
`
`is illustrated in Figure 4, reproduced below with highlights and annotations.

`U.S. Patent No. 8,942,107
`
`High-frequency data in an Ethernet network flows between a hub (1) and a PC
`
`
`
`(3a) along two pairs of conductive lines—a pair of transmit lines, highlighted in
`
`green (conductors 1 & 2), and a pair of receive lines, highlighted in red (conductors
`
`3 and 6). A central module (15a) and a remote module (16a) are placed between the
`
`hub and the PC, with the high-frequency data flowing through them. What’s novel
`
`about the system is that the remote module can convey information about the PC to
`
`the central module using different magnitudes of DC current along the same
`
`conductive lines as the high-frequency data without adversely affecting the high-
`
`frequency data (if present). This is generally represented in the figure above by the
`
`black and blue arrows between the central and remote modules. The different
`
`magnitudes of DC current convey information about the PC, and this can happen
`
`even when the PC is powered off.

`U.S. Patent No. 8,942,107
`
` The central module has a direct connection to the remote module via a
`
`conventional Ethernet cable. More importantly, the central module can be
`
`connected independently to multiple remote modules. The diagram below shows
`
`the invention being used within an exemplary network consisting of a central
`
`module and four remote modules.
`
`
`This arrangement is commonly referred to as a “star” or “hub and spoke”
`
`network, in which the central module has a direct connection to each of the remote
`
`modules, allowing it to identify, communicate with, and manage each of them—as
`
`opposed to a “bus” network where communication lines (and thus the connection)
`
`are shared among several devices. 11

`U.S. Patent No. 8,942,107
`
`This system allowed the patentees to solve a number of problems associated
`
`with prior-art asset-management systems. As the patent explains:
`
`[The prior art was] generally incapable of detecting the electrical
`
`connection status of equipment[;] it cannot detect the physical
`
`location of equipment, the identifying name of equipment is not
`
`permanent, and the monitored assets must be powered-up.
`
`Therefore, a method for permanently identifying an asset by
`attaching an external or internal device to the asset and
`communicating with that device using existing network
`wiring or cabling is desirable. . . . It would also be desirable to
`communicate with the device without requiring the device or
`the asset to be connected to alternating current (AC) power.
`
`Such a device would allow a company to track its assets, locate
`
`any given asset, and count the total number of identified assets at
`
`any given time, thus significantly reducing its [total cost of
`ownership] of identified assets.12
`
`In short, the patentees were looking for a way to identify, communicate with,
`
`and manage distributed assets in a network, over existing network wires, even when
`
`the assets are turned off. The innovative devices, methods, and systems described
`
`and claimed by the ’107 Patent achieve each of these goals. Specifically, they are
`
`

`
`able to: (1) transmit information about assets—e.g., a company’s computers—
`
`along the same lines already being used to convey high-frequency data
`
`communications to the assets, without interrupting the high-frequency data
`
`communications13; and (2) convey information about the assets even when the
`
`assets are powered off.14
`
`C. Person of Ordinary Skill
`
`The Parties appear to agree that a person of ordinary skill in the relevant art
`
`with respect to the ’107 Patent as of April 1998 would have an undergraduate
`
`degree or the equivalent in the field of electrical engineering or a related field, and
`
`one to three years of experience with Ethernet networks. Alternatively, a greater
`
`
`13 See, e.g., Ex. 1003: ’107 Patent at 12:3–5 (“The system transmits a signal
`
`over pre-existing network wiring or cables without disturbing network communi-
`
`cations . . . .”).
`
`14 See, e.g., Ex. 1003: ’107 Patent at 5:4–7 (describing an embodiment of the
`
`invention “capable of identifying the existence and location of network assets
`
`without power being applied to the assets.”); id. at 12:54–56 (“[T]he system
`
`provides a means for permanently identifying the location of network assets
`
`without applying power to the assets.”).

`
`length of experience could replace the degree requirement, and an advanced degree
`
`in electrical engineering could replace the experience requirement.15

`
`
`III. ARGUMENTS AND AUTHORITIES
`
`A. Priority
`
`The ’107 Patent claims priority to Provisional Patent Application No.
`
`60/081,279 (Ex. 1027; the “’279 Provisional Application”), which was filed on
`
`April 10, 1998. The priority dates for the De Nicolo references are March 26, 1998
`
`(De Nicolo ’468) and March 12, 1998 (De Nicolo ’666). Petitioner contends the De
`
`Nicolo references are prior art because their priority dates predate the filing of the
`
`’279 Provisional Application by a few weeks. As set forth below, however, the
`
`inventors of the ’107 Patent conceived their invention before the priority dates of
`
`the De Nicolo references and diligently reduced it to practice. Further, contrary to
`
`Petitioner’s arguments, the ’279 Provisional Application discloses each of the
`
`limitations of the ’107 Patent claims at issue, the testimony regarding diligence is
`
`15 See Ex. 2054: Madisetti Dec. ¶ 33; Ex. 2059: Deposition of Rich Seifert
`
`[Petitioner’s technical expert] (Oct. 14, 2016) (“Seifert IPR Dep.”) at 52
`
`(testifying that there are no substantive differences between Dr. Madisetti’s
`
`definition of a person of ordinary skill and his own—“I think they are almost
`
`identical”).

`U.S. Patent No. 8,942,107
`
`fully corroborated, and the named inventors on the patent art the only true
`
`inventors. For at least these reasons, the De Nicolo references are not prior art to
`
`the ’107 Patent.
`
`1. Legal Standards
`a. Burden
`
`In an IPR, the petitioner always shoulders the burden of persuasion, by a
`
`preponderance of the evidence, to establish that the challenged claims are not
`
`patentable. See In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1375 (Fed. Cir.
`
`2016). When a patent owner attempts to antedate an alleged prior-art reference, the
`
`patent owner must meet a burden of production—i.e., a burden to produce some
`
`evidence establishing prior conception and diligent reduction to practice. See
`
`Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1379–80 (Fed. Cir.
`
`2015); see also Magnum Oil Tools, 829 F.3d at 1375–76. The Board has repeatedly
`
`recognized that a patent owner bears no more than a burden of production in this
`
`context, and the petitioner must ultimately meet its burden of proof to show that an
`
`alleged prior-art reference in fact qualifies as prior art. See, e.g., Neste Oil OYJ v.
`
`Reg Synthetic Fuels, LLC, IPR2013-00578, Paper 54 at 17 (PTAB March 12, 2015);
`
`Olympus Am., Inc. v. Perfect Surgical Techniques, Inc., IPR2014-00233, Paper 56 at 15

`
`22–23 (PTAB Feb. 3, 2016).
`
`b. Written-Description Requirement
`
`“The purpose of the written description requirement is to assure that the
`
`public receives sufficient knowledge of the patented technology, and to
`
`demonstrate that the patentee is in possession of the invention claimed.” Zoltek
`
`Corp. v. U.S., 815 F.3d 1302, 1308 (Fed. Cir. 2016). “[W]ritten description is about
`
`whether the skilled reader of the patent disclosure can recognize that what was
`
`claimed corresponds to what was described; it is not about whether the patentee
`
`has proven to the skilled reader that the invention works, or how to make it work,
`
`which is an enablement issue.” Alcon Research Ltd. v. Barr Labs., Inc., 745 F.3d
`
`1180, 1191 (Fed. Cir. 2014). To meet this standard, “[a]n applicant is not required
`
`to describe in the specification every conceivable and possible future embodiment
`
`of his invention.” Rexnord Corp. v. Laitram Corp., 274 F.3d 1336, 1344 (Fed. Cir.
`
`2001).16 Likewise, “[a] specification may, within the meaning of 35 U.S.C. § 112
`
`
`16 See also, e.g., Cordis Corp. v. Medtronic AVE, Inc., 339 F.3d 1352, 1364 (Fed.
`
`Cir. 2003) (“The disclosure as originally filed does not . . . have to provide in haec
`
`verba support for the claimed subject matter at issue.”).

`
`para. 1, contain a written description of a broadly claimed invention without
`
`describing all species that [the] claim encompasses.” Utter v. Hiraga, 845 F.2d 993,
`
`998 (Fed. Cir. 1988).
`
`c. Corroboration
`
`Under pre-AIA § 102(g), a patent owner can antedate an alleged prior-art
`
`reference by showing earlier conception and reasonable diligence in reducing to
`
`practice. Perfect Surgical Techs., Inc. v. Olympus Am., Inc., — F.3d —, 2016 WL
`
`6694956, at *2 (Fed. Cir. Nov. 15, 2016). “Reasonable diligence must shown
`
`throughout the entire critical period, which begins just prior to the competing
`
`reference’s effective date and ends on the date of the invention’s reduction to
`
`practice.” Id. Further, an inventor’s testimony regarding his reasonable diligence
`
`must be corroborated by evidence. Brown v. Barbacid, 436 F.3d 1376, 1380 (Fed.
`
`Cir. 2006). “A ‘variety of activities’ may corroborate an inventor’s testimony of
`
`reasonable diligence and such corroborating evidence is considered ‘as a whole’
`
`under a rule of reason.” Perfect Surgical, 2016 WL 6694956, at *2 (citing Barbacid,
`
`436 F.3d at 1380).
`
`As the Federal Circuit recently held, [a] patent owner need not prove the
`
`inventor continuously exercised reasonable diligence throughout the critical
`
`period; it must show there was reasonably continuous diligence.” Perfect Surgical,

`U.S. Patent No. 8,942,107
`
`2016 WL 6694956, at *3 (emphasis in original) (citing Tyco Healthcare Grp. v.
`
`Ethicon Endo-Surgery, Inc., 774 F.3d 968, 975 (Fed. Cir. 2014); Monsanto Co. v.
`
`Mycogen Plant Sci., Inc., 261 F.3d 1356, 1370 (Fed. Cir. 2001)). Likewise, “an
`
`inventor is not required to work on reducing his invention to practice every day
`
`during the critical period.” Id. (citing Monsanto, 261 F.3d at 1369). “And periods of
`
`inactivity within the critical period do not automatically vanquish a patent owner’s
`
`claim of reasonable diligence.” Id. In Monsanto, for example, the Federal Circuit
`
`upheld a jury’s presumed finding that an inventor was reasonably diligent where
`
`there was no corroborating evidence of any activity for a series of months.
`
`Monsanto, 261 F.3d at 1370.
`
`The Federal Circuit explained that this is the standard because “the point of
`
`the diligence analysis is not to scour the patent owner’s corroborating evidence in
`
`search of intervals of time where the patent owner has failed to substantiate some
`
`sort of activity.” Rather, the point is “to assure that, in light of the evidence as a
`
`whole, ‘the invention was not abandoned or unreasonably delayed.’” Perfect
`
`Surgical Techs., 2016 WL 6694956, at *3 (quoting Barbacid, 436 F.3d at 1379).
`
`2. The ’279 Provisional Application fully discloses the inventions claimed
`by the ’107 Patent.
