`MEMORANDUM OPINION AND ORDER
`
`Before the Court is Defendants Alcatel-Lucent USA, Inc., Alcatel-Lucent Holdings, Inc.,
`
`ALE USA Inc., and AMX LLC’s (collectively, “Defendants”) Motion for Summary Judgment of
`
`Indefiniteness. (Doc. No. 99.) Plaintiffs Chrimar Systems, Inc. d/b/a CMS Technologies and
`
`Chrimar Holding Company LLC (“Plaintiffs” or “Chrimar”) filed a response (Doc. No. 101) and
`
`Defendants filed a reply (Doc. No. 105). On March 10, 2016, the Court held a hearing. Having
`
`considered the parties’ arguments and for the reasons stated below, the Court DENIES
`
`Defendants’ Motion for Summary Judgment (Doc. No. 99).
`
`BACKGROUND
`
`Plaintiffs allege Defendants infringe claims 31, 35, 36, 43, 56, and 60 of the ’012 Patent,
`
`claims 1, 5, 43, 72, 83, 103, 104, 111, and 125 of the ’107 Patent, claims 1, 31, 59, 69, 72, 73,

`
`
`Case 6:15-cv-00163-JDL Document 122 Filed 03/28/16 Page 2 of 12 PageID #: 3567
`
`106, 142, and 145 of the ’760 Patent, and claims 1, 7, 26, 40, and 69 of the ’838 Patent. (Doc.
`
`No. 99, at 2.) Plaintiffs contend that “[a]ll four patents share, in substance, a common
`
`specification and disclose inventions related to managing devices that connect to a wired
`
`network.” (Doc. No. 97, at 1.) Specifically, the ’107 Patent is a continuation of the ’012 Patent,
`
`and the ’760 Patent and the ’838 Patent are continuations of the ’107 Patent.
`
`For reference, background on the ’012 Patent is provided. The ’012 Patent is titled
`
`“System and Method for Adapting a Piece of Terminal Equipment,” and relates to tracking of
`
`devices that are connected to a wired network. See generally ’012 Patent. More specifically, the
`
`’012 Patent describes permanently 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.” ’012 Patent at 1:67–2:2. The ’012 Patent refers to that device as the
`
`“remote module.” Id. at 3:22–26. The asset can then be managed, tracked, or identified by using
`
`the remote module to communicate a unique identification number, port ID, or wall jack location
`
`to the network monitoring equipment, or “central module.” Id. at 6:7–13, 8:66–9:4. The ’012
`
`Patent further discloses that “asset identification” may be done in a way “that does not use
`
`existing network bandwidth.” Id. at 3:10–12. These concepts are reflected in the patents’
`
`asserted claims, and independent claim 31 is set forth below for reference:
`
`31. An adapted piece of Ethernet data terminal equipment comprising:
`
`an Ethernet connector comprising a plurality of contacts;
`and
`
`
`
`at least one path coupled across selected contacts, the selected contacts
`
`
`comprising at least one of the plurality of contacts of the Ethernet
`
`
`connector and at least another one of the plurality of contacts of the
`
`
`Ethernet connector,
`
`wherein distinguishing information about the piece of Ethernet data
`
`
`terminal equipment is associated to impedance within the at least
`
`
`one path.
`
`’012 Patent at 18:62–19:5 (Claim 31).

`Case 6:15-cv-00163-JDL Document 122 Filed 03/28/16 Page 3 of 12 PageID #: 3568
`
`Defendants move for summary judgment that the certain asserted claims of the ’012,
`
`’107, and ’760 Patents are invalid because the following phrases fail to comply with the
`
`definiteness requirement of 35 U.S.C. § 112, ¶ 2: (1) “at least one condition [applied]” (’107
`
`Patent, Claims 1, 104); (2) “detection protocol” (’012 Patent, Claim 35; ’107 Patent, Claim 72;
`
`’760 Patent, Claim 59); and (3) “DC current” (’107 Patent, Claim 72).
`
`LEGAL STANDARD
`
`Summary Judgment Standard
`
`“Summary judgment is appropriate in a patent case, as in other cases, when there is no
`
`I.
`
`
`
`genuine issue as to any material fact and the moving party is entitled to judgment as a matter of
`
`law.” Nike Inc. v. Wolverine World Wide, Inc., 43 F.3d 644, 646 (Fed. Cir. 1994); FED. R. CIV.
`
`P. 56(c).
`
`II.
`
`Indefiniteness
`
`
`
`Indefiniteness is a question of law. Teva Pharms. USA, Inc. v. Sandoz, Inc., 723 F.3d
`
`1363, 1368 (Fed. Cir. 2013). “[D]etermination of claim indefiniteness is a legal conclusion that
`
`is drawn from the court's performance of its duty as the construer of patent claims.” Exxon
`
`Research & Eng'g Co. v. United States, 265 F.3d 1371, 1376 (Fed. Cir. 2001) abrogated on
`
`other grounds by Nautilus v. Biosig Instruments, Inc., - U.S. -, - n. 9, 134 S.Ct. 2120, 2130 n. 9,
`
`189 L.Ed.2d 37 (2014). Indefiniteness is a challenge to the validity of the patent that must be
`
`established by clear and convincing evidence. Nautilus, 134 S.Ct. at 2130, n. 10 (citing Microsoft
`
`Corp. v. i4i Ltd. Partnership, - U.S. -, -, 131 S.Ct. 2238, 2242, 180 L.Ed.2d 131 (2011) for the
`
`clear-and-convincing standard applicable to challenges to invalidity and declining to alter this
`
`standard).

`Case 6:15-cv-00163-JDL Document 122 Filed 03/28/16 Page 4 of 12 PageID #: 3569
`
`
`
`Under 35 U.S.C. § 112 ¶ 2, “[t]he specification shall conclude with one or more claims
`
`particularly pointing out and distinctly claiming the subject matter which the applicant regards as
`
`his invention.” “A lack of definiteness renders invalid ‘the patent or any claim in suit.’”
`
`Nautilus, 134 S.Ct. at 2125 (citing 35 U.S.C. § 282, ¶ 2(3)). Until recently, a claim was
`
`indefinite “only when it [was] not amendable to construction or insolubly ambiguous.” Id. at
`
`2127. The Supreme Court rejected this standard as too imprecise. Id. at 2130.
`
`
`
`Under the new standard, “a patent is invalid for indefiniteness if its claims, read in light
`
`of the specification ..., and the prosecution history, fail to inform, with reasonable certainty,
`
`those skilled in the art about the scope of the invention.” Id. at 2124 (emphasis added). In
`
`rejecting the prior standard, the court found it insufficient “that a court [could] ascribe some
`
`meaning to a patent’s claims.” Id. at 2130. Reasonable certainty is something more precise than
`
`insolubly ambiguous, but short of absolute precision. Id. at 2129–30. In describing the new
`
`standard the court “mandates clarity.” Id. at 2129.
`
`
`
`The Supreme Court noted the “delicate balance” to the indefiniteness analysis. Id. at
`
`2128. In summarizing this balance post-Nautilus, the Federal Circuit explained that “[t]he
`
`definiteness standard ‘must allow for a modicum of uncertainty’ to provide incentives for
`
`innovation, but must also require ‘clear notice of what is claimed, thereby appris[ing] the public
`
`of what is still open to them.’” Interval Licensing LLC v. AOL, 766 F.3d 1364, 1370 (Fed. Cir.
`
`2014) (emphasis added) (quoting Nautilus, 134 S.Ct. at 2128–29).
`
`
`
`The Supreme Court did not apply the new standard in Nautilus.1 The Federal Circuit,
`
`however, has both applied the new standard and provided guidance on the level of precision
`
`
`1 The court declined to apply the new “reasonable certainty” standard to the claim language at issue in Nautilus,
`“mounted ... in spaced relationship with each other.” Nautilus, 134 S.Ct. at 2131. The language describes the
`location of two electrodes on a cylinder held in the user's hand. Id. at 2127. In concluding the language was not

`
`required. Interval, 766 F.3d at 1369–71. “Although absolute precision or mathematical
`
`precision is not required, it is not enough as some of the language in ... prior cases may have
`
`suggested, to identify ‘some standard for measuring the scope of the phrase.’” Id. at 1370–71
`
`(quoting Datamize, LLC v. Plumtree Software, Inc., 417 F.3d 1342, 1351 (Fed. Cir. 2005)).
`
`“The claims, when read in light of the specification and the prosecution history, must provide
`
`objective boundaries for those of skill in the art.” Id at 1371 (emphasis added) (relying on
`
`Nautilus, 134 S.Ct. at 2130 & n. 8). In noting the necessity for objective boundaries, the Federal
`
`Circuit relied on the finding in Halliburton Energy Servs., Inc. v. M–I LLC that “[e]ven if a claim
`
`term's definition can be reduced to words, the claim is still indefinite if a person of ordinary skill
`
`in the art cannot translate the definition into meaningfully precise claim scope.” Id. (emphasis
`
`added) (relying on Halliburton, 514 F.3d 1244, 1251 (Fed. Cir. 2008)).
`
`
`
`Other parts of the indefiniteness inquiry remain the same. Indefiniteness is still
`
`“evaluated from the perspective of someone skilled in the relevant art at the time the patent was
`
`filed.” Nautilus, 134 S.Ct. at 2128. Claims must also still “be read in light of the patent’s
`
`specification and prosecution history.” Id. at 2128.

`
`
`Case 6:15-cv-00163-JDL Document 122 Filed 03/28/16 Page 6 of 12 PageID #: 3571
`
`In their motion for summary judgment, Defendants argue that the phrase “at least one
`
`condition” is indefinite because the intrinsic record provides no guidance regarding the objective
`
`bounds of the term “condition.” (Doc. No. 99, at 5.) Defendants submit that “it was not until
`
`November 5, 2014 (more than 10 years after the earliest filing date of the original specification)
`
`that the abstract of the ’107 patent eventually was amended to add the term ‘condition.’” Id.
`
`Defendants further argue that the dependent claims claim certain “conditions,” therefore
`
`indicating what things “condition” is not limited to, but providing no further bounds to what is
`
`meant by the term “condition.” Id. at 6. Plaintiffs respond that “‘[a]t least one condition’ . . .
`
`refers to something that will cause different magnitudes of current to flow through the at least
`
`one path when applied to a contact. (Doc. No. 101, at 3.) Plaintiffs contend that while this may
`
`be broad, it is not indefinite. Id. Plaintiffs also urge that in the context of the patents-in-suit, “the
`
`term ‘condition’ refers to an electrical condition.” Id. at 4–5 (footnotes omitted). Defendants
`
`reply that Plaintiffs’ proposal of “something that will cause different magnitudes of current to
`
`flow” demonstrates the indefiniteness of the recited “condition.” (Doc. No. 105, at 2.)
`
`Here, the claim language itself indisputably provides some bounds regarding the term
`
`“condition.” For example, claim 1 of the ’107 Patent demonstrates that the “condition” causes
`
`“different magnitudes of DC current flow.” See ’107 Patent at 17:19–21 (“…the different
`
`magnitudes of DC current flow to result from at least one condition applied to at least one of the
`
`contacts.”) The recited language alone provides context. Defendants’ own expert recognizes this
`
`requirement of the claim language and goes through several examples of what a “condition
`
`applied” could be understood to mean, including those examples a person of ordinary skill in the
`
`art would understand to change the magnitudes of DC current as claimed. (Doc. No. 99-6
`
`(“Seifert Decl.”) at ¶¶ 134–137.)

`
`
`Case 6:15-cv-00163-JDL Document 122 Filed 03/28/16 Page 7 of 12 PageID #: 3572
`
`Moreover, by virtue of their own arguments regarding claim differentiation, Defendants
`
`concede that at least several lower bounds of the claim scope are known and easily understood.
`
`(Doc. No. 99, at 6.) Defendants’ expert also discusses some of these examples and opines how
`
`he would understand their application as recited in the claim. See, e.g., Seifert Decl. at ¶¶ 137,
`
`138 (“[t]o the extent that a ‘voltage’ condition is applied to the contacts, a person of ordinary
`
`skill in the art would understand what is required because it is a clear application of Ohm’s law
`
`to a recited element of the claim.”) Plaintiffs’ expert also describes some of these same
`
`conditions and indeed describes how he would understand their operation in the recited claim
`
`language as a person of ordinary skill in the art. (Doc. No. 101-5 (“Baxter Decl.”) at ¶¶ 47–49
`
`(“[a] person of ordinary skill in the art, reading this claim, would understand that the ‘condition’
`
`that would be applied…must be an electrical condition such as voltage or impedance, since the
`
`claim requires that the Ethernet terminal equipment must be configured to draw different
`
`magnitudes of current in response…”) While the claimed “at least one condition” may
`
`encompass more than one “condition” as recited in the claims, the surrounding claim language
`
`(e.g. result of “different magnitudes of DC current flow”) as well as the other intrinsic and
`
`extrinsic evidence demonstrate that “condition” refers to electrical conditions.2
`
`For these reasons, the Court finds that the phrase “at least one condition” does not fail to
`
`“inform those skilled in the art about the scope of the invention with reasonable certainty.”
`
`Nautilus, 134 S. Ct. at 2129; see also In re Gardner, 427 F.2d 786, 788 (C.C.P.A. 1970)
`
`
`2 Defendants argue that limiting the “at least one condition…” to an “electrical condition” violates the principles of
`claim differentiation. (Doc. No. 99, at 6.) However, the dependent claims that actually modify the “at least one
`condition” recite the condition as specific examples of electrical conditions—voltage and impedance. ’107 Patent at
`18:27 – 32 (Claims 22, 23.) Therefore, those dependent claims, which recite specific subsets of electrical conditions,
`further limit was is claimed to the specific electrical condition recited. Claim 61, which recites “electrical condition”
`is distinguishable as it modifies the path as a function of an electrical condition, whereas claim 1 refers to the
`magnitude of DC current flow being a function of a condition. ’107 Patent at 12–16 (Claim 61). Moreover,
`Defendants’ expert agrees with this reading of the claims. (Doc. No. 101-6, Seifert Deposition, at 75:12-76:14. (“the
`electrical condition in Claim 61 is modifying the path…”).)

`

`
`condition” is not indefinite and means “at least one electrical condition.”
`
`II.
`“detection protocol” (’012 Patent, Claim 35; ’107 Patent, Claim 72; ’760 Patent,
`Claim 59)
`
`Plaintiffs’ Proposal
`
`Defendants’ Proposal
`
`No construction necessary, as the term should be afforded its plain
`and ordinary meaning.
`
`To the extent that the Court finds that construction is required,
`Plaintiffs contend that the plain and ordinary meaning of
`“detection protocol” is “detection scheme, rule, or procedure”
`
`
`Indefinite
`
`Defendants argue that the term “detection protocol” is indefinite because “there is no
`
`objective boundary as to what constitutes a ‘detection protocol,’ and the patents provide no
`
`assistance in understanding the scope of the terms.” (Doc. No. 99, at 7.) Plaintiffs argue that the
`
`term is not indefinite and that “Mr. Seifert [(Defendants’ expert)] admits that a person of
`
`ordinary skill in the art would understand the term ‘protocol’ and would be familiar with data-
`
`communications protocols.” (Doc. No. 101, at 8.) Defendants further argue that “encoded
`
`signals sent pursuant to the invention do not use Ethernet network communication—in other
`
`words, whatever ‘protocol’ [is] used is distinct from the Ethernet data communication protocols
`
`known to those of skill in the art.” (Doc. No. 105, at 3.)
`
`Turning first to the recited claims, claim 35 of the ’012 Patent, for example, recites: “35.
`
`The piece of Ethernet data terminal equipment according to claim 31 wherein the impedance
`
`within the at least one path is part of a detection protocol.” ’012 Patent at 19:20–22 (Claim 35)
`
`(emphasis added). The specification does not use the terms “detection protocol” or “protocol,”
`
`but does discuss “detecting.” For example, the specification discloses that “[r]elocation of the
`
`electronic equipment with the attached communication device to another location on the network
`
`
`

`
`Chrimar Systems, Inc.
`Exhibit 2020-8

`
`
`
`Case 6:15-cv-00163-JDL Document 122 Filed 03/28/16 Page 9 of 12 PageID #: 3574
`
`is detected immediately and may be used to update a database,” and that “[f]rom the foregoing it
`
`will be understood that the invention provides a system and method for remotely detecting and
`
`reading an asset identity and location.” ’012 Patent at 3:32-35, 16:44-46 (emphasis added).
`
`Although the specification does not use the terms “detection protocol” or “protocol,” the
`
`plain meaning of “protocol” is sufficiently clear and does not become any less clear when joined
`
`with “detection” as it is claimed. Here, for example, Defendants’ own expert acknowledges that,
`
`at least in the context of IEEE 802.3 communications, a “protocol” is “a series of procedures,
`
`possibly including syntax and semantics of exchanged information to achieve some desired end.”
`
`(Doc. No. 101, Ex. F, Feb. 2, 2016 Seifert Deposition, at 106:8-10.) Similarly, Plaintiffs’ expert
`
`opined that the plain and ordinary meaning of “protocol” would be a “scheme, rule, or
`
`procedure,” which in the context of being claimed as a “detection protocol” would mean a
`
`“detection scheme, rule, or procedure.” Baxter Decl. at ¶ 70. Plaintiffs’ expert further went on
`
`to opine that “[i]n the context of these claims, ‘detection protocol’ means that the equipment is
`
`configured or designed so that the magnitude of the current (flow) or the impedance in the path
`
`allow it to detect or determine some information about the equipment at the other end of the
`
`path.” Id. at ¶ 74. In this regard, the experts are in general agreement as to the plain and ordinary
`
`meaning of the term “protocol” in the art, and the Court finds that “detection protocol” can be
`
`understood by a person of ordinary skill in the art with reasonable certainty in view of the recited
`
`claims and the specification.
`
`Defendants’ expert’s concern with Plaintiff’s expert’s position regarding his stated
`
`understanding of the term “detection protocol” is that it would leave designers with no guidance
`
`as to how to avoid infringement of the claims because a “detection protocol” could be “conjured
`
`up at a later time by a different party.” Seifert Decl. at ¶ 146. However, the test for

`
`Case 6:15-cv-00163-JDL Document 122 Filed 03/28/16 Page 10 of 12 PageID #: 3575
`
`indefiniteness is not whether a device or process would infringe. Instead, the test is whether the
`
`claim read in light of the specification delineating the patent, and the prosecution history,
`
`informs, with reasonable certainty, those skilled in the art about the scope of the invention.
`
`Nautilus, 134 S. Ct. at 2124. Overall, Defendants have failed to demonstrate indefiniteness
`
`under this standard. Therefore, the Court finds the term “detection protocol” to be definite, and
`
`finds that no further construction is necessary.
`
`“DC current” in Claim 72 of the ’107 Patent
`
`III.
`
`Plaintiffs’ Proposal
`
`No construction necessary, as the terms should be afforded their
`plain and ordinary meaning.
`
`To the extent that the Court finds that construction is required,
`Plaintiffs contend that “current” and “current flow” mean the
`same thing and the plain and ordinary meaning of “current” and
`“current flow” is “a flow of electric charge”
`
`Defendants’ Proposal
`
`Dependent claim 72 of the
`’107 patent is indefinite for
`lack of antecedent basis.
`
`Defendants argue that the phrase “at least one magnitude of DC current” recited in claim
`
`
`
`72 of the ’107 Patent has no antecedent basis in claim 1, from which it depends, and is therefore
`
`indefinite. (Doc. No. 99, at 11.) Plaintiffs respond that “the specification refers equally to the
`
`‘current’ between two devices and the ‘current flow’ between them.” (Doc. No. 101, at 11.)
`
`Alternatively, Plaintiffs submit that “‘the magnitudes of DC current flow’ are magnitudes of the
`
`‘DC current’ drawn through the same ‘at least one path.’” Id. at 12. Defendants reply that
`
`“[w]hether the ‘DC current’ of claim 72 refers back to the ‘at least one path for the purpose of
`
`drawing DC current’ or the ‘DC current flow’ that results from the condition applied to a contact
`
`makes a difference in claim scope.” (Doc. No. 105, at 4.)
`
`
`
`
`
`
`Claims 1 and 72 of the ’107 Patent recite:
`
`1. A piece of Ethernet terminal equipment comprising:
`
`an Ethernet connector comprising first and second pairs of

`at least one condition applied to at least one of the contacts
`of the first and second pairs of contacts, wherein at least
`one of the magnitudes of the DC current flow to convey

`
`72. The piece of Ethernet terminal equipment of claim 1 wherein at least one
`magnitude of the DC current is part of a detection protocol.
`
`’107 Patent at 17:11–25 (emphasis added), 20:47–49 (Claim 72) (emphasis added).
`
`
`
`As a preliminary matter, as discussed in the Court’s corresponding claim construction
`
`opinion, the claims and the specification demonstrate that, at least for purposes of the present
`
`case, any distinction between “DC current” and “DC current flow” is a distinction without a
`
`difference. See ’012 Patent at 2:16-18, 6:48-54, 7:17-21, 7:40-42, 7:48-50, 8:7-8, 8:11-17,
`
`8:27-31, 8:52-53, 12:32-38. Indeed, Defendants’ expert uses these terms without distinction in
`
`describing the “current loop path” of the incorporated prior art ’260 Patent. See Doc. No. 101,
`
`Ex. G, Jan. 21, 2016 Seifert Decl. at ¶ 40 (“…the figure relates to a device that sends a low DC
`
`current over the existing Ethernet wiring and detects whether the path is present or broken, by
`
`the presence (or lack of) current flow in the path.”) Therefore, the Court construed the terms
`
`“current” and “current flow” to mean “a flow of electric charge.” Because there is no discernable
`
`distinction between the terms, as discussed above and in the Court’s claim construction opinion,
`
`the “at least one magnitude of the DC current” in Claim 72 has sufficiently clear antecedent basis
`
`in the “magnitudes of DC current flow” in Claim 1. See Energizer Holdings Inc. v. Int’l Trade

`
`Case 6:15-cv-00163-JDL Document 122 Filed 03/28/16 Page 12 of 12 PageID #: 3577
`
`Comm’n, 435 F.3d 1366, 1371 (Fed. Cir. 2006) (holding that “an anode gel comprised of zinc as
`
`the active anode component” provided implicit antecedent basis for “said zinc anode”); see also
`
`Ex Parte Porter, 25 U.S.P.Q. 2d (BNA) 1144, 1145 (B.P.A.I. 1992) (“The term ‘the controlled
`
`fluid’ . . . finds reasonable antecedent basis in the previously recited ‘controlled stream of fluid
`
`. . . .’”).
`
`The Court therefore rejects Defendants’ indefiniteness argument and finds that the “at
`
`least one magnitude of the DC current” in Claim 72 has sufficiently clear antecedent basis in the
`
`“magnitudes of DC current flow” in Claim 1.
`
`CONCLUSION
`
`
`
`For the foregoing reasons, the Defendants’ Motion for Summary Judgment (Doc. No. 99)
`
`is DENIED.
`
`
`
`
`
`
`
`
`
` So ORDERED and SIGNED this 28th day of March, 2016.
