  • 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

    “Trove contends that a person of ordinary skill in the art “would have had an undergraduate degree in mechanical engineering or equivalent coursework, and a year or more of experience in designing, prototyping, and/or manufacturing fluid containers or similar products” and that “[m]ore work experience may substitute for a lower level of education, and vice versa.” Pet. 15 (citing Ex. 1002 ¶ 25). While CamelBak offers “a similar, though slightly different level,” it nonetheless “discerns no material difference between the definitions provided by the parties for purposes of the Board’s decision in this proceeding.” PO Resp. 27. That being the case, we adopt Trove’s proposed definition of the level of skill in the art, as it is 2 JP 2002-211613A, published July 31, 2002 (Ex. 1004, “Nakajima”). 3 WO 2004/063042 A2, published July 29, 2004 (Ex. 1006, “Ribarits”). 4 US 4,485,963, issued Dec. 4, 1984 (Ex. 1007, “Panicci”). 5 US 6,523,711 B1, issued Feb. 25, 2003 (Ex. 1008, “Hughes”). reasonable and consistent with what is reflected in the asserted prior art and the specification of the ’250 patent. B. Claim Construction” slip op. at 7

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

    “We will not bite. CamelBak’s original assertion—that the plain and ordinary meaning of the constituent parts of “mouth” and “piece” is “a piece (or part) that goes in the mouth”—underscores the fallacy of CamelBak’s additional physical contact requirement. PO Resp. 28 (emphasis added). Indeed, in support of that earlier assertion, CamelBak pointed to the very dictionary definition that we relied on at institution in construing “mouthpiece” as a part that either “goes in the mouth or to which the mouth is applied.” See id. at 31 (citing Ex. 2005 (emphasis added)). Even the original testimony of CamelBak’s own expert confirms that one skilled in the art “would understand that the term ‘mouthpiece’ is commonly known in the art as a part designed for a user’s mouth,” without any requirement for physical contact with the mouth. Ex. 2016 ¶ 58 (citing Ex. 2005) (emphasis added)). And nothing in the Specification limits that common understanding. Although, indisputably, the Specification contemplates an embodiment where the user physically contacts the mouthpiece with their teeth (i.e., a bite-actuated mouthpiece), it also contemplates an embodiment where the user simply inserts the bottle in their mouth and commences fluid flow by squeezing it. See Ex. 1001, 10:9–13. That disclosure supports a meaning of “mouthpiece” that simply requires placement in the opening of the user’s mouth without necessarily incurring physical contact with some portion of the mouth, such as the teeth, tongue, or lips. Indeed, had CamelBak wished to premise the meaning of “mouthpiece” on some sort of physical contact with the mouth, it knew how to do so. For instance, the independent claims of CamelBak’s earlier ’255 patent, which is the subject of the related 1137 IPR, are limited in just such a manner, as they recite “wherein the resilient mouthpiece is adapted to resiliently compress responsive to compressive forces applied to the resilient mouthpiece by a user’s teeth.” Ex. 2023, at 20–25 (emphasis added). Thus, we reject CamelBak’s attempt to narrow our construction of “mouthpiece” to something other than “a part (as of an instrument) that goes in the mouth or to which the mouth is applied.” Neither the intrinsic nor extrinsic evidence supports the narrower construction proposed by CamelBak.” slip op. at 11

  • Expert testimonyPetitioner expert discountedDecided for patent owner

    “In reply, Trove argues that CamelBak’s “novel” construction that the mouthpiece moves with rotational motion about that same axis of rotation defined by the two joint as the pivotal mount and in the same direction as the pivotal mount “are inconsistent with the claim language’s plain and ordinary meaning and find no support in the intrinsic and extrinsic record.” See Pet. Reply 16. But, because we find that, when properly construed, the claimed “pivotal movement with the pivotal mount” about “two joints that define a pivotal axis” requires that the mouthpiece rotate about the same axis and in the same direction as the pivotal mount, we reject Trove’s argument as unavailing. And, although we agree with Trove that Nakajima’s mouthpiece engages in counter-clockwise rotation about a “Second Pivot Axis” when Nakajima’s lid 4 is opened (id. at 20–22), that rotation is about a different axis—one defined by Nakajima’s protrusions 24 rather than the claimed “pivotal axis” defined by Nakajima’s hinge shafts 19—and in a different manner—an upward and counterclockwise path rather than the claimed “pivotal movement with the pivotal mount” defined by Nakajima’s lid 4. Finally, in an alternative theory, Trove and its expert use “image- manipulation tools” in an attempt to show that Nakajima’s mouthpiece engages in some initial “clockwise-rotation” with Nakajima’s lid as it is opened. See Pet. Reply 18–24. We reject that theory as entirely conjectural and unsupported by the evidence.” slip op. at 39

    “We disagree. As discussed above, the proper construction of “for pivotal movement with the pivotal mount” requires that the mouthpiece mirror the rotational movement of the pivotal mount, i.e., rotate about the same axis as the pivotal mount and in the same direction as the pivotal mount. See supra § II.B.3. But Nakajima’s mouthpiece does neither, and, thus, does not exhibit the claimed “pivotal movement with the pivotal mount” about “two joints that define a pivotal axis for . . . the pivotal mount axis,” as properly construed.” slip op. at 36

Although the parties dispute whether an “isolated island” is shown in the prior art, neither party proposes a construction for the term “isolated island.” We agree that the arguments presented do not require construction of “isolated island.” The issues can be determined on the plain meaning of the term in view of the arguments made.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successAnalogous artMotivation foundUnpatentable

    “We find that Petitioner has sufficiently shown Yu is analogous art to Okashita. Both references are directed to the manufacture of semiconductors, which we find to be the field of endeavor. Ex. 1004, 1:47– 58; Ex. 1005, 1:16–26. More specifically, we agree with Petitioner and find that both references are in the same field of endeavor because they relate to SOI configuration. Pet. Reply 6 (citing Pet. 7–8, 39–40; Ex. 1002 ¶¶ 77–80, 90–91). Because we find the references relied upon are in the same field of endeavor, we need not reach whether they are reasonably pertinent to the problem faced by the inventor. We also find that Petitioner has shown rational underpinnings for combining Okashita and Yu. Pet. 43–44. That the references have differences is not the test. Rather, the test is whether a person of ordinary skill in the art would have had motivation to combine them. We find there is sufficient motivation. Id. at 43 (citing Ex. 1005, 2:4–17; Ex. 1002 ¶¶ 177– 178). 3. Conclusion on Ground 3 Patent Owner does not argue any other reason that Ground 3 has not been sufficiently shown. Based on the full record, we determine that Okashita and Yu teach or suggest all the limitations of claim 3 and that one of ordinary skill in the art would have combined the references in the manner asserted with a reasonable expectation of success. We thus determine that Petitioner has established by a preponderance of the evidence that claim 3 would have been obvious over the combination of Okashita and Yu.” slip op. at 21

    “of the substrate is based on Dr. Thompson’s testimony. In his first declaration, Dr. Thompson relies on Conn’s paragraphs 31 and 35 to support the annotated version of Figure 2 in the Petition. Ex. 1003 ¶¶ 83–84. As discussed above, paragraphs 31 and 35 do not disclose that the anchor vias 14 are located in the corner of the substrate. The second annotated Figure 2 shown in Petitioner’s Reply does not appear in either of Dr. Thompson’s declarations (See Ex. 1003, Ex. 1034). It appears to be mere attorney argument not evidence. Dr. Thompson testified in his deposition that the second annotated version is based on his interpretation of Conn. Ex. 2009, 45:2–46:9. Because Dr. Thompson’s testimony is not adequately supported by the disclosure of Conn, we find that his testimony on the point of whether Conn discloses anchor vias located in the corner of the substrate is entitled to little, if any, weight. 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). Therefore, because Petitioner has the burden of proof, we find that Petitioner has not shown that Conn discloses this limitation.” slip op. at 27

    “We agree with Petitioner that the differences between the parties’ proposed levels of skill in the art are immaterial for the purposes of this Decision. We apply Petitioner’s proposed level of skill in the art because it appears consistent with the problems addressed in the ’826 patent and the prior art. Further, our determination in this case would not be affected if we were to adopt Patent Owner’s proposed level of skill in the art.” slip op. at 11

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

    “Claim 1 uses the term “comprising” which is open-ended and normally does not exclude additional, unrecited elements. See Mars Inc. v. H.J. Heinz Co., 377 F.3d 1369, 1376 (Fed. Cir. 2004). This is in contrast to the phrase “consisting of.” See Multilayer Stretch Cling Film Holdings, Inc. v. Berry Plastics Corp., 831 F.3d 1350, 1358 (Fed. Cir. 2016) (there is an “exceptionally strong presumption that a claim term set off with ‘consisting of’ is closed to unrecited elements.”). The use of comprising in claim 1, thus, weighs against a construction limiting claim 1 to direct contact between the backside metal layer and the bottom surface of the semiconductor substrate. Additionally, we note that claim 1 does not recite that the backside metal layer is “directly on” or “formed on” the bottom surface or similar language that would suggest “direct contact” may be required. For these reasons, we determine that the language of claim 1 does not support Patent Owner’s proposed construction.” slip op. at 17

    “time it was made, we consider the level of ordinary skill in the pertinent art at the time of the invention. Graham v. John Deere Co., 383 U.S. 1, 17 (1966). In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed.
