`AMENDED EXHIBIT B TO THE JOINT PATENT CASE STATUS
`REPORT AND CLAIM CONSTRUCTION STATEMENT
`
`TENNANT’S PROPOSED CLAIMS TERMS
`FOR CONSTRUCTION WITH INTRINSIC AND EXTRINSIC EVIDENCE
`
`Pursuant to the Pretrial Scheduling Order (ECF No. 43, modified by ECF No. 62)
`
`and the agreement of the parties, Defendant Tennant Company (“Tennant”) hereby
`
`provides its list of terms, phrases, or clauses that Tennant believes require the Court’s
`
`construction, including: (i) Tennant’s proposed construction of each disputed claim term,
`
`phrase, or clause; (ii) an identification of all references from the specification or
`
`prosecution history to support Tennant’s constructions (the “Intrinsic Evidence”); (iii) an
`
`identification of any extrinsic evidence on which Tennant intends to rely either in support
`
`of its proposed construction or to oppose another party’s proposed construction (the
`
`“Extrinsic Evidence”); and (iv) the identity of every witness, including experts, that
`
`Tennant proposes to call to offer testimony relating to claim construction; and for each
`
`expert, a summary of the opinion to be offered in sufficient detail to permit a meaningful
`
`
`
`CASE 0:20-cv-00358-ECT-HB Doc. 75-2 Filed 06/09/21 Page 2 of 39
`
`deposition of that expert. Tennant incorporates the proposed briefing schedule submitted
`
`in the Joint Claim Construction Statement (ECF No. 64).
`
`Tennant makes this disclosure based on information presently known to it, without
`
`the benefit of full discovery. Tennant reserves the right to supplement or amend the
`
`information contained herein in response to any arguments, allegations, or evidence
`
`presented by Plaintiff, as information is discovered or confirmed during fact discovery,
`
`information is discovered, confirmed or provided by a party’s consultant or expert after the
`
`party’s contentions have been served, new products are launched or accused, amendments
`
`are made to the amended complaint and/or any counterclaims, information is learned from
`
`or positions are taken by another party during the exchange of contentions or the
`
`constructions process set forth in the Pretrial Case Management Order, rulings are made
`
`by the Court, amendments are made to infringement or validity contentions, or as otherwise
`
`permitted or required under the Federal Rules of Civil Procedure, the Local Rules, and the
`
`Court’s Pretrial Case Management Order. Further, Tennant reserves the right to change its
`
`position in response to Plaintiff’s Exhibit A (the Plaintiff’s proposed claims terms for
`
`construction with intrinsic and extrinsic evidence), changes in the parties’ constructions,
`
`and as information is learned during the course of claim construction discovery.
`
`
`
`Tennant relies on the asserted patents, the asserted patents’ prosecution history,
`
`including the file histories of related patents and applications. Further, Tennant identifies
`
`the following preliminary identification of extrinsic evidence which has been previously
`
`provided to Plaintiff:

`
`With regard to (iv) above, Tennant identifies Dr. Mario Tremblay and incorporates
`
`his declarations and CV as submitted in the pending petitions for inter partes review of
`
`U.S. Patent No. RE 45,415 (“the ‘415 Patent”), Exhibits 1003 and 1004 in IPR2021-00602
`
`and Exhibits 1103 and 1104 in IPR2021-00625, produced herewith, as well as any potential
`
`testimony identified in the chart below. Dr. Tremblay reserves the right to testify in
`
`response to opinions raised or testimony or declarations offered by any OWT expert as
`
`needed. Dr. Tremblay may provide testimony through written declaration or live testimony
`
`to discuss indefiniteness issues, the level of skill in the art, and/or to explain how the terms
`
`and phrases at issue would be understood by one of ordinary skill in the art.
`
`Subject to the foregoing, Tennant identifies the preliminary claim constructions and
`
`supporting evidence in the chart below.1 Where any construction for a term or phrase is
`
`given, Tennant incorporates that construction into its other proposed constructions, e.g.,
`
`
`1 Tennant notes that, in its invalidity contentions, Tennant identified two additional phrases as
`unsupported by the specification: “flowing water at a flow rate no greater than 12 gallons per
`minute” and “delivers a current to the electrodes at a ratio of 1.75 amps or less per 3 square inches
`of active electrode.” OWT has failed to suggest any construction for these terms is necessary.
`Tennant maintains that these terms are unsupported by the specification, regardless of
`construction.

`
`where Tennant’s construction refers to “water,” such construction incorporates Tennant’s
`
`proposed construction of “water” as well. Tennant further submits the same terms or
`
`phrases should be construed in the same manner across all asserted claims and all asserted
`
`patents consistently.

`
`Water means any aqueous medium
`with resistance less than one ohm
`per square centimeter, that is, a
`medium that can support the
`electrolysis of water. In general, the
`lower limit of resistance for a
`medium that can support electrolysis
`is water containing more than 2000
`ppm total dissolved solids.
