Centillion Data Systems, Inc. v. American Management Systems, Inc.

ENTRY AND ORDER on Defendant’s Joint Motion for Expedited Ruling on the Insufficiency of Plaintiffs Opening Markman Brief (doc. no. 327). FOSTER, United States Magistrate Judge. This Cause came before the Court on the above-entitled motion. The parties were heard on their papers and at hearing held on March 22, 2001, the record of which is incorporated as if set forth herein. The defendants’ motion is granted as set forth below. The case management plans (September 26, 2000 (doc. no. 301) and December 7, 2000 (doc. no. 326), Part IV) and order of the Court (September 1, 2000 (doc. no. 290)) established a claims construction briefing and hearing process in accordance with Markman v. Westview Instruments, Inc., 52 F.3d 967 (Fed.Cir.1995) (“Markman I ”), affirmed, 517 U.S. 370, 116 S.Ct. 1384, 134 L.Ed.2d 577 (1996). This schedule required plaintiff Centillion Data Systems (“Centillion”) to file its Markman brief first, followed by the defendants’ response brief, and concluding with Centil-lion’s reply brief. The substantive law governing Markman rulings is now well-established: Construction of patent claims is a matter of law for the court. Claims are construed from the vantage point of a person of ordinary skill in the art at the time of the invention. In construing a claim, the court first looks to the intrinsic evidence of record, namely, the language of the claim, the specification, and the prosecution history. In most circumstances, the intrinsic evidence will provide sufficient information for construing the terms. If, after reviewing all available intrinsic evidence, some genuine ambiguity still exists in the claims, the court may look to extrinsic evidence as an aid in construing the claim language.... It may be used to assist the court’s understanding of the patent, or the field of technology, but not to vary or contradict the terms of the claims. Jackson v. Thomson Consumer Electronics, Inc., 139 F.Supp.2d 1003, 1006-07 (S.D.Ind.2001) (citations omitted). The procedure applicable to Markman rulings is a matter of expedience for the court. Because Centillion initiated this suit and its patents, which it drafted and prosecuted, are in issue, the Court required Centil- *? lion to provide its construction of its asserted claims first. Centillion filed its opening Markman brief on December 1, 2000 (doc. no. 321). It explained the ideas and technology behind the subject '270 and '290 patents, the law of claim construction, and the broad meanings of terms found in the first claims of each patent. Centillion gave its detailed construction of only one term in Claim 1 of the '270 patent, the term “exact charges actually billed.” At the hearing, the defendants advised that Centillion had previously identified 26 1 claims in the '270 patent and 9 2 claims in the '290 patent claims that it alleges have been and are being infringed. The defendants then filed the present motion in which they complain that Centillion’s brief fails to provide its construction of every claim allegedly infringed. They ask the Court to limit Cen-tillion’s allegations in this Cause to infringement of only Claim 1 of both patents, order Centillion to supplement its Mark-man brief with detailed constructions of all terms of Claim 1 in addition to “exact charges actually billed”, and to allow the defendants additional time to file their responsive Markman brief. In the alternative, they ask the Court to order Centillion to supplement its brief with constructions of every claim allegedly infringed in this Cause. At the hearing, the defendants produced a list of 45 claim terms that they contend are “genuinely in dispute”. Hearing Exhibit 1 (March 23, 2001 Rankin Wig-man letter, Exhibit A). Centillion contends that it produced “a wholly sufficient and complete Markman brief’ according to the relevant legal precedent. (Plaintiff Centillion Data System’s Memorandum in Opposition to Defendants’ Motion Concerning the Alleged Insufficiency of Centillion’s Opening Markman Brief (“Response”) (doc. no. 339), p. 9). It argues that, because a court’s Markman ruling should construe only those claim terms that the parties genuinely dispute, “unless and until defendants propose meanings for these terms that are different from their ordinary and accustomed meanings ..., there is no controversy for the Court to resolve nor any issue for Centillion to address in its submissions to the Court on claim interpretation.” (Response, p. 2) (original emphasis). In effect, Centillion contends that the defendants must brief their construction of Centillion’s asserted claims first so that Centillion will know which terms are genuinely disputed and need to be briefed. At the hearing on the present motion and in its brief, Centillion relied primarily on the Court of Appeals for the Federal Circuit’s decision in Vivid Technologies, Inc. v. American Science & Engineering, Inc., 200 F.3d 795, 803 (Fed.Cir.1999) (“only those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy”). The Court agrees with the teaching of Vivid Technologies and the other eases cited by Centillion and assures the parties that the Court’s Markman ruling will construe only those terms which the parties genuinely dispute. But this is a limit on the scope of the Court’s ruling, not on the parties’ briefing. As Vivid Technologies itself recognizes, the principle *1120 that a court should construe only disputed terms is intended to avoid dictal advisory opinions, id., 200 F.3d at 803 (“lest courts construe things that are not in dispute, thus rendering an advisory opinion”), and the court employed that principle in the context of determining whether a Mark-man ruling was ripe, in other words, whether sufficient discovery had occurred so that the parties and the court “knew with reasonable certainty which claim terms were at issue with respect to infringement”, id., so that the Court would not issue constructions of unasserted claims. The focus was not on whether the parties knew with reasonable certainty which claim terms were “at issue” with respect to construction but with respect to infringement, 3 The defendant in Vivid Technologies objected to the district court’s staying discovery and conducting a Markman hearing before there had been “sufficient discovery of the accused device to understand which claim elements and what aspects of their interpretation were at issue ... ”, id., 200 F.3d at 803 (emphasis added); there is no indication that the defendant objected to a lack of discovery on the plaintiffs claims constructions. Vivid Technologies .stands for the principle that, if a claim, an element of a claim, or an aspect of a claim is not material to a plaintiffs allegation of infringement, then a court need not and should not construe it as part of its Markman ruling. A corollary is that, before a Markman issue is ripe, discovery or case management should have progressed to the point where the parties and the court can be reasonably certain which claims terns are at issue, in other words, which claims and elements the plaintiff alleges were infringed. In this case, as cited above, Centillion has already identified the patent claims it alleges have been and are being infringed and, on inquiry from the Court, it did not identify any additional discovery it required in order to identify additional claims allegedly infringed. The Court concludes, therefore, that it and the parties are reasonably certain which claims and claim terms are at issue with respect to infringement and that the parties are ready for Markman briefing. Centillion is reluctant to provide its claims constructions first because it fears that “[wjhat defendants seek, of course, is to have Centillion further define and elaborate on the meaning of each term of every claim in the hope that Centillion will articulate some limitation that will enable defendants to construct an argument for non-infringement”, (Response, p. 3), and the defendants surmise that Centillion fears being locked into its constructions. 4 But the patents in issue are Centillion’s and it, not the defendants, initiated this suit alleging infringement of those patents. The logical order is for Centillion to provide its constructions of its claims first. Before it brought suit (or at least after it conducted *? the discovery it has in this case), Centillion must have already developed clear constructions of its relevant claims and clear positions on the manners in which the defendants’ products infringed those claims, so it is not an undue burden on Centillion to advance its constructions first. Furthermore, because the defending parties are entitled to review Centillion’s positions on construction before offering their own, a simultaneous exchange of constructions would not be warranted. Any risk that Centillion’s own constructions will prejudice its allegations of infringement or the validity of its patents is only incidental to the necessary Markman process in this Cause and is a risk that Centillion assumed when it filed this Cause. Centillion asserted that, through the various claims charts it served on the defendants, it has already identified the relevant claims and elements, or sub-parts, of claims that it is asserting and had adequately provided its construction of those claims and elements. In the materials submitted by Centillion at the hearing as Hearing Exhibit 1, are two claims charts for the '270 and '290 patents which Centil-lion produced to all parties in response to former-defendant MCI Worldcom’s Interrogatory no. 4. MCI WorldCom asked Cen-tillion to state its construction of each element of each claim of the patents that Centillion alleges were infringed by MCI WorldCom, including, but not limited to, identifying the structure, material, or acts in the patent specification that corresponds to any means-plus-function element of a claim. Centillion objected to the interrogatory on several grounds, but, subject to the objections, provided the claims charts as a “further response” to the interrogatory in light of its then current knowledge of MCI Worldcom’s product. While these charts appear to present some meanings of claims and references to the patent specifications — on the sufficiency of which the Court will not comment at this time — the charts were produced subject to Centillion’s objections and reflect its past understanding of a former party’s allegedly infringing product and its past positions regarding construction. Centillion also submitted copies of charts it had served on the defendants which were intended to specify which features of each defendant’s product infringed which claims or elements of claims of the patents in issue. But while these charts serve the purpose of identifying which claim terms are at issue with respect to infringement, they are not sufficient for providing Centillion’s construction of the relevant claims and elements of claims. Asserting that its claims terms should be given their ordinary and accustomed meanings, Centillion also argued that the defendants should first propose any unusual meanings they wish to ascribe to claim terms in order to more efficiently identify which terms are genuinely disputed and therefore require briefing and the Court’s construction. In addition to improperly focusing on genuinely disputed meanings instead of genuinely disputed claims as the standard for the parties’ briefing (at least the initial briefing) discussed above, this approach ignores what is often the crux of parties’ Markman disputes: disputes over what the ordinary or accustomed meanings of claim terms are. What is selfevident to an infringement accuser might not be to an alleged infringer, especially in application, as a review of the case law illustrates. See, e.g., Markman I, supra (construction of “inventory”); Advanced Cardiovascular Systems, Inc. v. Scimed Life Systems, Inc., Cause No. IP 98-1108-C-H/G, Entry on Defendants’ Motion for Summary Judgment of Noninfringement, 2000 WL 684182, 2000 U.S. Dist. LEXIS 7105 (S.D.Ind., Feb. 9, 2000). By Centillion *1122 providing its constructions of all material terms of all claims and elements of claims that it is asserting the defendants infringed, the defendants will be able to determine which constructions they dispute and then can brief only those terms. The Court can then limit its construction to only those claims and terms that are genuinely disputed. In addition, because “[c]laims are construed by the court as they would be understood by persons of skill in the field of the invention, for patents are written by and for skilled artisans”, Vivid Technologies, 200 F.3d at 804, Centillion’s explication of even the ordinary and accustomed meanings of asserted terms in a claim assists the Court because “[j]udges are not usually ‘conversant in the particular technical art involved,’ or capable of reading the patent specification and claims as one skilled in the art might”, Charles E. Hill & Associates v. Compuserve, 65 F.Supp.2d 924, 928 (S.D.Ind.1999). If it results that the defendants do not dispute Centillion’s proposed ordinary and accustomed meaning of a term within an asserted claim and, therefore, the Court need not construe that particular term, the then-agreed construction might assist the Court’s construction of disputed terms because claim terms are to be construed consistently with one another and with the overall purpose of the patent. See Forest Laboratories, Inc. v. Abbott Laboratories, 239 F.3d 1305, 1309-10 (Fed.Cir.2001) (“We also construe independent claims consistently with the claims that depend from them”); CVI/Beta Ventures, Inc. v. Tura LP, 112 F.3d 1146, 1160 (Fed.Cir.1997), ce rt. denied, 522 U.S. 1109, 118 S.Ct. 1039, 140 L.Ed.2d 105 (1998); Southwall Technologies, Inc. v. Cardinal IG Co., 54 F.3d 1570, 1579 (Fed.Cir.) (“Interpretation of a disputed claim term requires reference not only to the specification and prosecution history, but also to other claims”), cert. denied, 516 U.S. 987, 116 S.Ct. 515, 133 L.Ed.2d 424 (1995); Nichols v. Strike King Lure Co., No. CIV. A. 3:00-CV-1950-B, Memorandum Opinion and Order, 2000 WL 1593616, *6, 2000 U.S. Dist. LEXIS 15781, *18 (N.D.Texas, Oct.25, 2000); Leggett & Platt Inc. v. Hickory Springs Manufacturing Co., No. 99 C 2614, Memorandum Opinion and Order, 2000 WL 1269363, *3, 2000 U.S. Dist. LEXIS 13063, *8 (N.D.Ill., Sept.5, 2000); Purdue Pharma, L.P. v. Boehnnger Ingel-heim, GmbH, 98 F.Supp.2d 362, 375 (S.D.N.Y.2000), affirmed and remanded, 237 F.3d 1359 (Fed.Cir.2001); Charles E. Hill & Assoc., 65 F.Supp.2d at 927. Centillion asked the Court to order the defendants to provide a full answer to its Interrogatory no. 18 before requiring Cen-tillion to file a new Markman brief. The interrogatory asks: “For every claim of the Centillion patents, if you contend that you do not infringe such claim, explain why you do not infringe each element of each claim for each of [the accused products].” Because this interrogatory in effect seeks to shift the order and burdens of the Markman process, the request was denied. After the Court issues its Markman constructions, the defendants will be in a position to meaningfully answer this interrogatory. In presenting its new Markman brief, Centillion is not limited to providing its constructions of the claim terms identified by the defendants in the March 13, 2001 Rankin Wigman letter (Hearing Exhibit no. 2) but must provide its constructions of all material and relevant terms of all asserted claims. The Court admonishes Centillion not to provide minimalist interpretations in an attempt to effectively shift the initial burden to the defendants. Finally, because “the scope of a means-plus-function claims is strictly limited to the ‘corresponding structure^ material or acts’ described in the specification, and *1123 equivalents of that structure”, Jackson, 139 F.Supp.2d at 1007 (applying 35 U.S.C. § 112, ¶ 6), Centillion must identify the specific structures, materials, and acts of the specification that apply to each means-plus-function claim term construed. Schedule Thirty days from the date of the March 22, 2001 hearing, Centillion must file a new Markman brief setting forth its complete constructions of all terms in all asserted claims in conformity with the rulings set forth above. The defendants must file their responding briefs no later than 30 days after Centillion files its brief. Centil-lion shall have 15 days after the filing of each response brief to file a reply thereto. No later than thirty days after filing its Markman reply briefs, Centillion shall make its disclosures under Fed.R.Civ.P. 26(a)(2) for Markman hearing experts. The defendants shall file their Rule 26(a)(2) Markman expert disclosures no later than 30 days after Centillion files its disclosures. No later than 15 days after the defendants file their Markman response briefs, the parties shall file a joint notice of the earliest available times for the Court to convene a Markman hearing. By the same deadline, the parties shall file a joint motion for any necessary amendments to the case management plan. The parties shall seek leave of Court if their Markman briefs will exceed 50 pages. Footnotes [1] Three independent and twenty-three dependent claims.
