    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner

      “We disagree with Patent Owner that a person of ordinary skill in the art would have understood that limitation 1.2 must be performed before limitations 1.3 or 1.4. See Ex. 1001, 35:21–24. See Interactive Gift Exp., Inc. v. Compuserve Inc., 256 F.3d 1323, 1342 (Fed. Cir. 2001) (“Unless the steps of a method actually recite an order, the steps are not ordinarily construed to require one.” (citing Loral Fairchild Corp. v. Sony Corp., 181 F.3d 1313, 1322 (Fed. Cir. 1999)). The evidence suggests that a “target printer” is any printer that is ultimately selected for fabricating the object, and such a printer could send its configuration information either before or after that determination is made in limitation 1.2. This interpretation does not render the word “target” meaningless. At some point, a printer must be determined to be the target printer, which is the one intended to ultimately fabricate the three-dimensional object. But the target printer still exists, and is capable of being queried, before that determination is made. We find the examples in the ’774 patent pertinent to this question. The ’774 patent states that “the target printer may include more than one printer.” Ex. 1001, 18:66–67. In discussing the step of “query target printer for properties 306” (Fig. 3A), the ’774 patent states that “[i]n one aspect, numerous queries are sent to numerous printers, e.g., for use in selecting one or more of the printers as the target printer.” Id. at 19:8–10. Alternatively, “the query is sent to a printer that is not necessarily the target printer as described herein, e.g., when the query or information received from a response to the query is used for the selection of the target printer.” Id. at 19:11–14. Importantly, the second embodiment states that the queried printer “is not necessarily the target printer,” suggesting that the queried printer could be the target printer even before it is determined to be such. Id. at 19:11–12 (emphasis added). Based on the evidence of record, a person of ordinary skill in the art would have understood that the “target printer” can be determined after the query recited in limitation 1.3 or the reception of configuration information recited in limitation 1.4. Thus, the evidence does not impose an ordering between limitations 1.2 and 1.3 or between limitations 1.2 and 1.4. The evidence also does not support Patent Owner’s argument that the two reverse-order examples in the ’774 patent are unclaimed embodiments.” slip op. at 10

      “We disagree that Petitioner’s arguments are based on impermissible hindsight, because they are based on the disclosures in Douglas and Mark, and Petitioner has articulated a persuasive reason to combine those references without referring to the ’774 patent itself, as we discuss below. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (an obvious rationale is not improper hindsight if it “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”).” slip op. at 29

      “On this record, we do not find Patent Owner’s proposed experience level of at least five years in measurement and analysis of coefficient of friction to be supported. As to the necessity of experience in textile engineering and fiber science, Patent Owner’s position, although not supported by declarant analysis of the factors listed above, is consistent with the disclosure of the ’854 patent, which describes features of a mesh layer in textile and fiber terms. See e.g., Ex. 1001, 10:17–11:14, 12:65–13:8, 14:20–24. On the whole, however, we do not discern on this record how specific experience in textile engineering and fiber science of a person of ordinary skill would materially alter the outcome at this stage of the proceeding. For purposes of this decision only, we apply Patent Owner’s proposed definition of a person of ordinary skill in the art, except for the requirement of five years of experience in measurement and analysis of coefficient of friction. The level of skill in the art remains an open issue in this proceeding. Further submissions by the parties may include argument and evidence that would assist in the resolution of this issue at the close of trial.” slip op. at 8

Patent Owner contends the terms “mesh layer” and “coefficient of friction” require construction. Prelim. Resp. 14–16; Sur-reply 2–5. We have considered the parties’ arguments and discuss them below with regard to each of the terms Patent Owner contends should be construed. Because our determination that Petitioner demonstrates at least one challenged claim meets the threshold for institution (see SAS Inst., 138 S. Ct. at 1359–60) is not based on construing the term “mesh layer” or “coefficient of friction,” we determine we need not construe either claim term at this stage of the proceeding.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner

      “We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard. Luminara Worldwide, LLC v. Liown Elecs. Co., 814 F.3d 1343, 1353 (Fed. Cir. 2016) (“Absent lexicography or disavowal, we do not depart from the plain meaning of the claims.”); In re Am. Acad. Of Sci.

Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). We note that the ’854 patent specification sets forth a definition for the coefficient of friction between the surfaces of the mesh material and the slide surface. Ex. 1001, 4:38–46. As stated above, however, we do not expressly construe any claim term at this stage of the proceeding. Should the parties address the construction of “coefficient of friction” at trial, we will make a determination after the close of evidence and any hearing.” slip op. at 13

Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91.

Ex. 2006 ¶ 119. In particular, Dr. Yao persuasively testifies that one of ordinary skill in the art would have believed that the charge cut-off voltage was no more than 4.2 V, and most likely equal to “about 4 V.” Id. ¶¶ 119–122. Petitioner argues that because the battery of Uemura is charged “to” a maximum voltage of 4.3 V, Uemura discloses the claimed charge cut-off voltage under either Petitioner’s or Patent Owner’s construction of the term. Pet. Reply 11–12 (citing Ex. 1009 ¶ 81; Ex. 1044 ¶¶ 56–59). This argument is not persuasive because Mr. Juzkow unambiguously testified that charging in Uemura stopped when the applied voltage reached 4.3 V, and Uemura discloses that the battery was charged “at” a voltage ranging from 4.3 V to 2.0 V, not “to” such a voltage.

      “Claim 1 affirmatively recites, for example, “a plurality of layers under the top layer.” Ex. 1001, 4:13. Claim 1 also affirmatively recites that the “plurality of layers compris[es] a bottom routing layer having signal traces thereon.” Id. at 4:14–15. So, claim 1 requires a bottom routing layer having signal traces. Claim 1 then recites “where[] none of the signal traces of the bottom routing layer are located over ball pads of the ball pad layer which are disposed in an area within two ball pad pitches of the corner of the die.” Id. at 4:17–20. This recitation serves to describe the “signal traces of the bottom routing layer.” The recitation does not affirmatively recite a required location of any ball pads. Likewise, the claim as a whole also does not state that the ball pad layer comprises ball pads disposed within two ball pad pitches of the corner of the die. Rather, the claim recites “said ball pad layer having a plurality of ball pads” without affirmatively indicating where those ball pads must be located within the ball pad layer. Thus, on the present record, we interpret claim 1’s recitation of “none of the signal traces . . . within two ball pad pitches of the corner of the die” as requiring that no signal traces of the bottom routing layer be located over ball pads of the ball pad layer disposed within two ball pad pitches of the corner of the die if any such ball pads exist in this location. We do not interpret claim 1 as affirmatively requiring ball pads disposed within two ball pad pitches of the corner of the die.

      “Here, we decline to exercise discretion to deny this Petition based upon multiple Petitions for three reasons. First, as we explain in Section III(H) of this decision, the Petition is strong on the merits, and Patent Owner has, at this stage, offered little argument refuting the merits. Second, Patent Owner’s burden to respond to both petitions is lessened by Patent Owner’s familiarity with much of the prior art at issue. As Patent Owner emphasizes, all or nearly all of the art in the Petitions was previously raised either during prior examination or in other inter partes reviews. Indeed, it seems likely that, if the Cree IPR (or related follow on IPRs) proceeds to a decision on the merits, there may be little left unresolved for the instant Petition. Institution here, however, provides Petitioner an opportunity to challenge the ’961 patent based on Krames in the event that the IPR based on Cree does not reach a decision on the merits. Third, while the two petitions present different invalidity grounds (addressing the same claims) and, as explained above, are not wholly redundant, the two parallel petitions have a great deal of overlap. Prelim. Resp. 26 (arguing that the two petitions are “redundant”). Because portions of the petitions are similar, this also reduces Patent Owner’s burden to respond.
