`
`MEMORANDUM AND ORDER ON CLAIM CONSTRUCTION
`
`This patent case is before the Court for construction of the disputed claim terms
`
`in United States Patents No. 6,637,514 (“the ’514 Patent”), 7,111,687 (“the ’687
`
`Patent”), 8,066,076 (“the ’076 Patent”), 8,122,948 (“the ’948 Patent”), 8,272,435
`
`(“the ’435 Patent”), 8,281,864 (“the ’864 Patent”), 8,540,018 (“the ’018 Patent”),
`
`8,573,306 (“the ’306 Patent”), 8,746,332 (“the ’332 Patent”), and 8,776,893 (“the
`
`’893 Patent”) (collectively, the “Patents-in-Suit”). The parties agree that construction
`
`of the disputed claim terms will apply consistently to all Patents-in-Suit.
`
`The Court conducted a hearing pursuant to Markman v. Westview Instruments,
`
`Inc., 517 U.S. 370, 390 (1996) (“Markman hearing”), on June 23, 2016. Based on the
`
`evidence before the Court, the arguments presented by counsel, and the governing

`
`legal authorities, the Court issues this Memorandum and Order construing those
`
`disputed claim terms that require construction.1
`
`I.
`
`BACKGROUND
`
`Plaintiff OneSubsea IP UK Limited (“OneSubsea”) is the owner by assignment
`
`of the Patents-in-Suit, and Plaintiff OneSubea UK Limited is an exclusive licensee.
`
`The Patents-in-Suit relate to the recovery of production fluids from an oil or gas well,
`
`particularly through a connection system for subsea flow interface equipment.
`
`Subsea “Christmas trees” have long been used in the oil and gas industry to
`
`control the flow of oil and gas coming from a well. The Christmas trees typically
`
`contain “fluid flow passages” or “bores.” The production bore communicates with the
`
`pipe from which the oil and gas flows. The annulus bore, on the other hand, is
`
`generally used for troubleshooting, well servicing, and well conversion operations
`
`rather than for the actual oil and gas production. A branch bore extends from the
`
`production bore to allow fluids to flow to a connected production flowline connected
`
`to a branch outlet. The rate of flow can be controlled through the use of a choke,
`
`either fixed or adjustable.
`

`
`The Patent Trial and Appeal Board (“PTAB”) recently instituted inter partes review
`(“IPR”) of all asserted claims of the ’018 Patent, the ’893 Patent, and the ’435 Patent.
`See Notices to Court Regarding IPR Institution Decisions [Docs. # 135 and # 144].
`Additionally, the PTAB will issue a decision on the petition for IPR of the ’306 Patent
`by October 19, 2016.

`
`In low pressure wells, the pressure of production fluids may need to be
`
`increased. In other circumstances, the production fluids may need to be treated.
`
`Installing a pump to increase pressure or a treatment apparatus in communication with
`
`an active subsea well can be difficult and interrupts production. Ian Donald, the
`
`named inventor for the Patents-in-Suit, invented systems and methods for installing
`
`a subsea pump or treatment apparatus that eliminated these problems.
`
`Defendant FMC Technologies, Inc. (“FMC”) markets products that OneSubsea
`
`asserts infringe the Patents-in-Suit. Specifically, OneSubsea alleges that FMC’s
`
`Enhanced Vertical Deepwater Tree and its Retrievable Choke and Flow Module are
`
`infringing.2
`
`OneSubsea filed its Opening Claim Construction Brief [Doc. # 122], FMC filed
`
`its Response [Doc. # 127], and OneSubsea filed its Reply [Doc. # 131]. Additionally,
`
`the parties filed a Joint Claim Construction Chart [Doc. # 136]. The parties worked
`
`together to narrow their disputed claim terms. Only the following terms remain in
`
`dispute and require construction by the Court: (1) branch, (2) divert and other forms
`
`of the word, (3) “flow diverter means” and “means to divert,” (4) connector, and
`
`(5) hub.
`
`2
`
`In its Counterclaim [Doc. # 24], FMC alleges that OneSubsea’s products infringe
`FMC’s Patent No. 6,715,554 and Patent No. 7,063,157. There are no disputed claim
`terms in either of FMC’s patents that require construction.

`
`
`Case 4:16-cv-00051 Document 147 Filed in TXSD on 07/12/16 Page 4 of 12
`
`The Court conducted a Markman hearing at which the parties presented
`
`evidence and argument regarding the proper construction of these terms. The Court
`
`found the parties’ oral argument to be extremely helpful and now construes the
`
`disputed claim terms.
`
`II. GENERAL LEGAL STANDARDS FOR CLAIM CONSTRUCTION
`
`“It is a bedrock principle of patent law that the claims of a patent define the
`
`invention to which the patentee is entitled the right to exclude.” Aventis Pharm., Inc.
`
`v. Amino Chems. Ltd., 715 F.3d 1363, 1373 (Fed. Cir. 2013) (quoting Phillips v. AWH
`
`Corp., 415 F.3d 1303, 1312 (Fed. Cir. 2005) (en banc)). The patent claims in issue
`
`must be construed as a matter of law to determine their scope and meaning. See, e.g.,
`
`Markman v. Westview Instruments, Inc., 517 U.S. 370, 390 (1996), aff’g, 52 F.3d 967,
`
`976 (Fed. Cir.) (en banc); Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d
`
`1295, 1317 (Fed. Cir. 2007).
`
`“There is a heavy presumption that claim terms are to be given their ordinary
`
`and customary meaning.” Aventis, 715 F.3d at 1373 (citing Phillips, 415 F.3d at
`
`1312-13; Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996)).
`
`Therefore, Courts must “look to the words of the claims themselves . . . to define the
`
`scope of the patented invention.” Id. (citations omitted); see also Summit 6, LLC v.
`
`Samsung Elec. Co., Ltd., 802 F.3d 1283, 1290 (Fed. Cir. 2015). The “ordinary and
`

`
`OSS Exhibit 2012, pg. 4

`IPR2016-00467
`
`
`
`Case 4:16-cv-00051 Document 147 Filed in TXSD on 07/12/16 Page 5 of 12
`
`customary meaning of a claim term is the meaning that the term would have to a
`
`person of ordinary skill in the art in question at the time of the invention, i.e., as of the
`
`effective filing date of the patent application.” Phillips, 415 F.3d at 1313; see also
`
`ICU Med., Inc. v. Alaris Med. Sys., Inc., 558 F.3d 1368, 1374 (Fed. Cir. 2009). This
`
`“person of ordinary skill in the art is deemed to read the claim term not only in the
`
`context of the particular claim in which the disputed term appears, but in the context
`
`of the entire patent, including the specification.” Phillips, 415 F.3d at 1313; ICU, 558
`
`F.3d at 1374.
`
`Intrinsic evidence is the primary resource for claim construction. See Power-
`
`One, Inc. v. Artesyn Techs., Inc., 599 F.3d 1343, 1348 (Fed. Cir. 2010) (citing
`
`Phillips, 415 F.3d at 1312). For certain claim terms, “the ordinary meaning of claim
`
`language as understood by a person of skill in the art may be readily apparent even to
`
`lay judges, and claim construction in such cases involves little more than the
`
`application of the widely accepted meaning of commonly understood words.”
`
`Phillips, 415 F.3d at 1314. For other claim terms, however, the meaning of the claim
`
`language may be less apparent. To construe those terms, the Court considers “those
`
`sources available to the public that show what a person of skill in the art would have
`
`understood disputed claim language to mean . . . [including] the words of the claims
`
`themselves, the remainder of the specification, the prosecution history, and extrinsic

`
`evidence concerning relevant scientific principles, the meaning of technical terms, and
`
`the state of the art.” Id.
`
`The claims “provide substantial guidance as to the meaning of particular claim
`
`terms.” Id. The Court may consider the context in which the terms are used and the
`
`differences among the claims. See id. “Because claim terms are normally used
`
`consistently throughout the patent, the usage of a term in one claim can often
`
`illuminate the meaning of the same term in other claims.” Id. Because the claims “are
`
`part of a fully integrated written instrument,” the Court may also consider the
`
`specification and the patent’s prosecution history. Id. at 1315, 1317. When the claims
`
`use separate terms, “each term is presumed to have a distinct meaning.” Primos, Inc.
`
`v. Hunter’s Specialties, Inc., 451 F.3d 841, 847 (Fed. Cir. 2006).
`
`III. CONSTRUCTION OF DISPUTED CLAIM TERMS
`
`The Court has carefully reviewed the Patents-in-Suit, specifically the claims and
`
`specifications. The Court also has considered each counsel’s arguments in the briefs
`
`and as presented at the Markman hearing. The Court also has reviewed and applied
`
`the governing Federal Circuit authority. On this basis, the Court construes the
`
`following disputed terms in the claims of the Patents-in-Suit.

`
`A.
`
`“Branch”
`
`The term “branch” is used in asserted claims in the ’948 Patent, the ’435 Patent,
`
`the ’306 Patent, and the ’893 Patent.3 OneSubsea argues that the term “branch” is
`
`defined in the Patents-in-Suit as “any branch of the manifold, other than a production
`
`bore of a tree.” See, e.g., ’306 Patent, 3:16-17. Where the inventor provides a
`
`definition for a claim term, “the inventor’s lexicography governs.” Phillips, 415 F.3d
`
`at 1316.
`
`Michael Chad Darby, FMC’s expert, testified during the Markman hearing that
`
`a branch must diverge from a flowpath and, therefore, cannot be the flowpath itself.
`
`OneSubsea agrees that the term “branch” does not include the production bore or the
`
`annulus bore. Based on the parties’ agreement as stated during the Markman hearing,
`
`as well as the intrinsic evidence before the Court, the term “branch” is construed to
`
`mean “an offshoot from a flowpath such as the production bore or the annulus bore,
`
`but does not include the production bore or the annulus bore.”
`
`B.
`
`“Divert” and Other Forms of that Word
`
`The term “divert” or a form of that word is used in asserted claims in the ’514
`
`Patent, the ’687 Patent, the ’948 Patent, the ’435 Patent, the ’306 Patent, the ’332
`
`3
`
`The term “branch” is also in Claim 19 of the ’332 Patent, but OneSubsea has
`withdrawn its infringement allegations related to this claim. See Notice of Narrowing
`of Asserted Claims [Doc. # 139].
`
`P:\ORDERS\11-2016\0051Markman.wpd 160712.1451
`

`
`OSS Exhibit 2012, pg. 7
`FMC vs. OSS
`IPR2016-00467
`
`
`
`Case 4:16-cv-00051 Document 147 Filed in TXSD on 07/12/16 Page 8 of 12
`
`Patent, and the ’893 Patent. OneSubsea argues that the term requires no construction
`
`when read in context, but if construction is deemed necessary, the term should be
`
`construed to mean “directing.”
`
`FMC argues that the term requires that there be a change in direction from one
`
`flowpath to a different flowpath. The Court agrees with FMC that the fluid is not
`
`“diverted” if the fluid simply moves through a single flowpath, even if the direction
`
`within the single flowpath changes. Therefore, the Court construes the term “divert”
`
`to mean that “the direction of the fluid’s flow is forced to change from its current
`
`flowpath to a different flowpath.”
`
`
`
`C.
`
`“Flow Diverter Means”/“Means to Divert”
`
`The ’687 Patent contains the limitations “flow diverter means” and “means to
`
`divert.” The parties agree that these terms are means-plus-function limitations under
`
`35 U.S.C. § 112.
`
`Construction of a means-plus-function limitation requires two steps. “First, the
`
`court must determine the claimed function.” Noah Sys., Inc. v. Intuit Inc., 675 F.3d
`
`1302, 1311 (Fed. Cir. 2012) (quoting Applied Med. Res. Corp. v. U.S. Surgical Corp.,
`
`448 F.3d 1324, 1332 (Fed. Cir. 2006)). In this case, the parties agree that the function
`
`in the “flow diverter means” term is “to divert fluids from a first portion of the first
`
`flowpath to a second flowpath.” See, e.g., FMC’s Response, p. 11. The parties agree
`
`P:\ORDERS\11-2016\0051Markman.wpd 160712.1451
`
`8
`
`OSS Exhibit 2012, pg. 8
`FMC vs. OSS
`IPR2016-00467
`
`
`
`Case 4:16-cv-00051 Document 147 Filed in TXSD on 07/12/16 Page 9 of 12
`
`also that the function in the “means to divert fluids” term is “to divert fluids returned
`
`from the second flowpath to a second portion of the first flowpath.” See id.
`
`Once the function is determined, “the court must identify the corresponding
`
`structure in the written description of the patent that performs the function.” Id.
`
`(quoting Applied Med. Res., 448 F.3d at 1332). At this step, the court must not import
`
`“structural limitations from the written description that are unnecessary to perform the
`
`claimed function.” Welker Bering Co. v. PHD, Inc., 550 F.3d 1090, 1097 (Fed. Cir.
`
`2008) (quoting Wenger Mfg., Inc. v. Coating Mach. Sys., Inc., 239 F.3d 1225, 1233
`
`(Fed. Cir. 2001)). “Structural features that do not actually perform the recited function
`
`do not constitute corresponding structure and thus do not serve as claim limitations.”
`
`Asyst Techs., Inc. v. Empak, Inc., 268 F.3d 1364, 1370 (Fed. Cir. 2001).
`
`The parties agree that, at a minimum, the structural elements are (1) a seal, (2) a
`
`production bore straddle having seals, and (3) a conduit with metal, inflatable or
`
`resilient seals. FMC proposes a construction, however, that also includes functional
`
`requirements. For example, OneSubsea proposes that the first structural element is
`
`a seal. FMC proposes that the seal must be “configured to seal an inside wall of and
`
`completely plug a bore.” Although the seal must function properly in order to divert
`
`fluids, the seal itself is the structural element, and it is improper to add the functional
`
`requirements that FMC suggests.
`
`P:\ORDERS\11-2016\0051Markman.wpd 160712.1451
`

`
`OSS Exhibit 2012, pg. 9
`FMC vs. OSS
`IPR2016-00467
`
`
`
`Case 4:16-cv-00051 Document 147 Filed in TXSD on 07/12/16 Page 10 of 12
`
`FMC’s proposed construction also includes extra structural elements that do not
`
`operate to divert the fluid. The “open crossover valve” and the “open production
`
`swab valve” suggested by FMC may allow the seal and the production bore straddle
`
`to operate as intended, but neither of these two structural elements performs the
`
`specific agreed function of diverting the fluid. See, e.g., Asyst, 269 F.3d at 1371.
`
`The Court agrees with FMC that, although possibly redundant, the straddle has
`
`seals “at opposing ends,” and the conduit has seals “on its outside.” Therefore, based
`
`on the parties’ submissions and the Court’s consideration of the record, the Court
`
`construes the structures in the means-plus-function limitations in the ’687 Patent to
`
`be (1) a seal; (2) a production bore straddle having seals at opposing ends; and (3) a
`
`conduit with metal, inflatable or resilient seals on its outside.
`
`D.
`
`“Connector”
`
`The term “connector” is used in asserted claims in the ’306 Patent, the ’893
`
`Patent, and the ’018 Patent. OneSubsea argues that the term requires no construction
`
`or, if any construction is necessary, should be construed to mean “a device that joins
`
`or attaches things together.” FMC argues that the term should be construed to mean
`
`“a device that attaches things together” because mere joining is insufficient. FMC
`
`argues also that the term “connector” should be construed to require that the
`
`attachment must “secure” things together. The Court concludes “join” is too vague
`
`P:\ORDERS\11-2016\0051Markman.wpd 160712.1451
`
`10
`
`OSS Exhibit 2012, pg. 10

`
`
`
`Case 4:16-cv-00051 Document 147 Filed in TXSD on 07/12/16 Page 11 of 12
`
`as it would encompass two items merely coming into contact with each other. There
`
`is no basis for implying the connector “secures” two items together. To the extent any
`
`construction is required, the Court construes the term “connector” to mean “a device
`
`that attaches things together.”
`
`E.
`
`“Hub”
`
`The term “hub” is used in asserted claims in the ’893 Patent and the ’018
`
`Patent. Each of these patents is currently before the PTAB for inter partes review.
`
`Additionally, the Court did not have adequate time during the Markman hearing to
`
`receive testimony regarding the definition of “hub” as understood by persons skilled
`
`in the art in the relevant industry. As a result, the Court declines at this time to
`
`construe the term “hub.” The Court will issue a construction of this term once the
`
`PTAB issues its decision in connection with the inter partes review of the ’893 and
`
`the ’018 Patents, and the parties submit additional information, if needed.
`
`IV. CONCLUSION
`
`The Court has considered the intrinsic evidence in the record. The Court also
`
`has considered the parties’ oral arguments and explanations during the Markman
`
`hearing, which the Court found very helpful and informative. Based on this
`
`consideration of the intrinsic evidence and the parties’ arguments, as well as the
