    “We agree with Petitioner that the ’690 patent does not limit the term “probe” to channel assessment. Pet. Reply 2–4. Reviewing the intrinsic evidence, the “Technical Field” of the ’690 patent states that “some embodiments relate to channel assessment probes,” implying others do not. Ex. 1001, 1:13–14. The ’690 patent further states that “receiver determined probes may be used in a variety of applications” including to “discover hidden nodes” and “off-site network diagnosis.” Id. at 2:20–27. In addition, the ’690 patent states that probes may be used for “network maintenance procedures,” to “replicate a potential problem, reach or discover a distant or previously undetected node on the network, or assist with network admissions procedures.” Id. at 4:25–38. Turning to the claims of the ’690 patent, the evidence of record does not establish that the independent claims recite anything unique or specific to channel assessment (although their scope covers that purpose). Furthermore, dependent claim 7 of the ’690 patent recites that the “probe” is used to diagnose a network problem, and dependent claim 13 recites that the “probe” is used to identify a hidden node. Restricting the independent claims to probes used solely for channel assessment would be contradictory to these dependent claims. Littlefuse, Inc. v. Mersen USA EP Corp., 29 F.4th 1376, 1380 (Fed.

    “We agree with Petitioner that a “physical layer probe” is “a probe that relates to the physical layer.” The term does not appear per se in the specification of the ’960 patent, nor in the prosecution history, but only in claims 9, 17, and 19. However, the term “physical layer” is well-known and is the first layer in the Open Systems Interconnection (OSI) network model. See, e.g., Ex. 1021, 35–40, 69; Ex. 1002 ¶¶ 49–50. The physical layer is used to transmit digital bits over a network, and defines the timing, mechanical, and physical network characteristics required for transmitting the data bits. Hence, a “physical layer probe” is a probe that relates to the physical layer. We need not, and do not, construe the term further to resolve the parties’ dispute. See Realtime, Vivid Techs., supra.

    “Prelim. Resp. 23 (citing Ex. 1013, 37) (annotated in red by Patent Owner). IEEE-802.16’s Table 5 shows that the CID is a field of a generic MAC header. Petitioner does not show sufficiently that the CID, located in the header, specifies content payload of a MAC message, as required by limitation 1A. Petitioner alternatively relies on IEEE-802.16’s ranging code index that it contends is another example of data that is in a ranging request parameter and is used for the ranging response payload. Pet. 15 (citing Ex. 1013, 49–51, 204–213, 576–579, 665–66; Ex. 1002 ¶ 149).

Although the parts of IEEE-802.16 that Petitioner cites disclose that the ranging code index is sent from the SS to the BS and is included in a ranging response (Ex. 1013, 49–51, 204–213, 576–579, 665–66), the cited parts do not disclose that the SS sends the ranging code index to the BS in a ranging request. Consequently, Petitioner has not established that IEEE- 802.16 anticipates a ranging code index that is a parameter of a ranging request specifying the content payload of the ranging response corresponding to limitation 1A. For the foregoing reasons, on this record, we determine that Petitioner has not shown a reasonable likelihood to prevail in showing that claim 1 is anticipated by IEEE 802.16.” slip op. at 18

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

    “As an initial matter, the recited expression “mounted to” is broad. The Federal Circuit has explained that words in a claim “will ordinarily be given their full meaning,” without imposing narrowing modifications on the claim language. Johnson Worldwide, 175 F.3d at 989, see also Virginia Panel, 133 F.3d at 865–66. As to whether the “mounted to” connection may be an indirect connection, the parties agree that an indirect connection is permitted — a view that is amply supported by the intrinsic record, as discussed above. With regard to the types of movement that may occur between a “string guide” and a corresponding “limb,” the intrinsic record shows that that various types of movements (including no movement at all) are characterized as “mounted to.” Slight variations of “mounted to,” occurring in the intrinsic record, are helpful in understanding the claim language — particularly because the ’015 patent itself uses such a variant (“mounted . . . on”) to describe the very connection (between a “string guide” and a “limb”) that is elsewhere, and in claim 1, is described as “mounted to.” See Ex. 1001, 5:23–26.” slip op. at 22

    “Patent Owner’ sole argument — i.e., that Stanziale ’771 fails to teach the “mounted to” limitation — is based upon its construction of the “mounted to” limitation, which permits the “string guide” to be rotatable relative the corresponding “limb,” but permits no other type of relative motion. See PO Resp. 4, 13–14. As discussed above, we do not accept Patent Owner’s construction of the “mounted to” limitation. In Stanziale ’771, first and second pulleys 145, 146, and interconnecting pivot 147 (all three of which Petitioner maps to claim 1’s “string guide[s]”) are pivotally connected to a number of intermediate members (e.g., lever arms or pushing arms 32, connecting elements 27, and constraining member 29) which are, in turn, pivotally connected to elastic members 10 (which Petitioner maps to claim 1’s “limb[s]”). See Pet. 41–42 (citing Ex. 1012 7:9–17, 8:26–8:13, 11:8–9, 14:18–15:22, 16:24–25, 16:29, 17:2, 17:15–17, 17:24–27, 19:12–30, 20:32–21:16, Figs. 1–7; Ex. 1016 ¶¶ 177–179); see also Ex. 1012 11:3–7, 11:34–12:4, 12:10–17, 16:29–18:3, 18:22–19:30, Figs. 8, 9, 10a, 10b. Therefore, Stanziale ’771, in Petitioner’s mapping, teaches the “string guide[s]” connected indirectly to the “limb[s].” Per the construction of the “mounted to” limitation employed herein (“connected to, either directly or indirectly”), Petitioner establishes, by a preponderance of the evidence, that Stanziale ’771 teaches the “string guide[s]” “mounted to” the “limb[s],” as recited in claim 1 of the ’015 patent. Contrary to Patent Owner’s concerns (see Paper 47, 1), the indirect connection between Stanziale ’771’s “string guide[s]” and “limb[s]” is not “unbounded.” Rather, the connection disclosed by Stanziale ’771 is the type of indirect connection supported by the intrinsic record. See supra § II.B. Patent Owner’s contention that “a POSA would be disinclined to rely on [Stanziale ’771] as a reference for the improved crossbow design disclosed in Claim 1” is not persuasive. See PO Resp. 38 (citing Ex. 2029 ¶ 46). The test for anticipation is whether a prior art reference discloses each and every element recited in the claim, not whether one of ordinary skill in the art would have been inclined to rely on the reference.

    “In the present proceeding, Petitioner proposed — and Patent Owner does not dispute (see PO Resp. 3) — the following definition of a person of ordinary skill in the art: A hypothetical POSA to which the ’015 Patent pertains would be a technical person who has at least some experience working in the field of archery, reviewing crossbows or engineering related to bows and/or crossbows, and is generally familiar with prior art crossbows. (Ex. 1016 ¶17.) Such a person would likely have at least a bachelor’s degree in mechanical engineering or, alternatively, would have several years of experience in the field of archery or engineering related to bows and/or crossbows. (Id.) Pet. 28. As discussed above, we adopt Petitioner’s description of a person of ordinary skill for the purposes of this Decision. See supra § II.A. Petitioner alleges various deficiencies in Mr. Teater’s background, education, and knowledge. Paper 39, 4–8. Nevertheless, Mr. Teater satisfies the definition, of a person of ordinary skill in the art, that Petitioner advanced. Specifically, Mr. Teater has reviewed crossbows for 14 years, encompassing the relevant priority date for the ’015 patent, during which time he wrote evaluations of various bows and crossbows, developed and published testing standards for crossbows, and served on the Archery Trade Association’s technical committee for standards and guidelines. Paper 41, 4 (citing Ex. 2029 ¶¶ 3, 4, 7). Accordingly, Mr. Teater satisfies Petitioner’s definition of “a technical person who has at least some experience working in the field of archery, reviewing crossbows or engineering related to bows and/or crossbows, and is generally familiar with prior art crossbows.” Pet. 28. Petitioner emphasizes that Mr. Teater “does not have a degree in mechanical engineering.” Paper 39, 4 (citing Ex. 2034, 1; Ex. 1034, 43:20–44:5). However, no degree of any kind is mandatory for satisfying Petitioner’s definition of a person of ordinary skill in the art. Indeed, Petitioner’s definition states that “[s]uch a person would likely have at least a bachelor’s degree in mechanical engineering or, alternatively, would have several years of experience in the field of archery or engineering related to bows and/or crossbows.” Pet. 28 (emphasis added).

    “We generally agree with Petitioner that the assumptions and approximations made in the calculations described in the ’397 patent to determine the external surface area of the components of the litter render the computations only a general approximation of the respective surface areas. See Pet. Reply 9–12. We need not, however, reach the issue of whether the 47% surface area limitation requires the use of the multi-step method disclosed in the ’397 patent because Petitioner followed that methodology in its arguments and evidence in its Reply. See Pet. Reply 13. Importantly, Patent Owner agrees that Petitioner followed the approach set forth in the ’397 patent, and argues that we need not construe “external surface area” to resolve any dispute between the parties. See PO Sur-reply 23–24 (arguing that we need not “determine whether ‘total external surface area’ must be determined using the same multi-step approach” in the ’397 patent to resolve the controversy because “the only calculation of external surface area relied on by Petitioner was presented in the Reply and it followed the methodology of the [’]397 Patent”); PO Supp. Sur-reply 2 (same).

    “review of the record, we find that Petitioner fails to articulate an adequate rationale for the combination of Goss and House. The Petition contains only a single sentence addressing the issue, without any citation to record evidence or declaration support. See Pet. 46. In addition, the assertion merely states the conclusion that a “PHOSITA would understand that there is a rational underpinning to combine the teachings of Goss and House as required under patent law because both are related to cat litter having similar characteristics.” Id. This assertion, at most, addresses the fact that Goss and House are in the same field or that they are analogous art, but does not explain why a PHOSITA would have been motivated to combine Goss and House. See id. In addition, the Petition lacks sufficient explanation of how Petitioner proposes to combine Goss and House. See Pet. 46–53. Instead, when Petitioner relies on House in this challenge, it appears to be a back-up argument in the event that we find Goss fails to disclose the limitation. Merely stating that Goss and House both disclose a limitation does not explain which aspects of House Petitioner proposes adding to Goss or what the resulting litter composition would look like. See id. The details of the resulting litter based on the combination of Goss and House matter here because it could impact whether all limitations of a given claim are satisfied by the combination. For example, Petitioner relies exclusively on specific examples from Goss for the 47% surface area limitation, but adding some aspects of House’s litter components to meet other limitations could undermine Petitioner’s reliance on Goss’s specific examples. The failure of the Petition to set forth a specific combination elides these issues. See Pet. 46–51. Petitioner’s Reply arguably addresses some of these concerns by providing a more fulsome motivation section, backed by new expert testimony, and specific litter examples based on Goss and various cellulose filler materials allegedly disclosed by House. See Pet. Reply 24–25 (citing Ex. 1013 ¶ 7); see also PO Sur-reply 18–22 (arguing that Petitioner’s Reply still fails to articulate an adequate motivation to combine). This analysis goes far beyond the limited analysis in the Petition, and Petitioner provides no reason why it could not have been included in the Petition. See Pet. Reply 24–25.

    “including a “predictive glucose value,” nowhere do we find the written description or drawings to have delineated such a second function expressly as “the present invention.” See, generally, Ex. 1001; see also Evolusion Concepts, Inc. v. HOC Events, Inc., 22 F.4th 1361, 1367 (Fed. Cir. 2022) (“We have repeatedly held that ‘it is not enough that the only embodiments, or all of the embodiments, contain a particular limitation to limit claims beyond their plain meaning.’”) (citation omitted). And, regardless of the exact wording, the concern we have is that without a persuasive, express, indication in the specification that the “second function” is specifically limited to “predicting glucose values,” it is a disfavored path to read limitations into the claims. Though understanding the claim language may be aided by the explanations contained in the written description, it is important not to import limitations into a claim that are not expressly part of may not be read into a claim when the claim language is broader than the embodiment. SuperGuide Corp. v. DirecTV Enterprises, Inc., 358 F.3d 870, 875 (Fed. Cir. 2004). The facts and written description here appear to fall more squarely into the category of cases where it is not enough to simply point to embodiments in the specification including the unrecited claim limitation. See Rambus Inc. v. Infineon Techs. Ag, 318 F.3d 1081, 1094 (Fed. Cir. 2003) (Even in cases where a “present invention” statement is provided, the Federal Circuit has explained that ‘[w]hile clear language characterizing ‘the present invention’ may limit the ordinary meaning of claim terms, . . . such language must be read in context of the entire specification and the prosecution history.”) (citation omitted); see also In re Bigio, 381 F.3d 1320, 1325 (Fed.

The plain and ordinary reading of limitation 1b is a method step of “evaluating sensor data using a second function to determine whether a parameter indicative of glucose value meets one or more non user settable second criteria.” Ex. 1001, 48:39–41.

Our understanding of “second function” is consistent with the specification of the ’215 patent.

    “We agree with Petitioner. Allum’s and Conlan’s design schemes, although different, are not mutually exclusive. Indeed, in addition to the pushbuttons, Conlan’s monitor includes a movement senor for detecting a full range of a subject’s movement and a memory in which data obtained by the monitor can be stored and later retrieved for evaluation. Ex. 1010, 2:60–63, 3:56–58, 4:47–49. As such, Conlan combines the pushbuttons for a user to tell the device about the user’s condition with a movement senor and a memory that enables the device to tell the user (or another person) about the user’s conditions (i.e., the user’s movements). Furthermore, even if Conlan did not disclose using two design schemes together, the differences in the design schemes identified by Patent Owner would not prevent one of ordinary skill in the art from considering combining the references. Rather, as Petitioner asserts, adding Conlan’s pushbuttons would allow the resulting device to gather additional data relating to a particular event, such as a feeling of dizziness, that pertains to the subject’s balance or movement. See Pet. 21–22 (citing Ex. 1010, 6:38–46; Ex. 1003 ¶¶ 78–79); see also id. at 34 (arguing that “switches 22, ‘dizziness,’ and, when depressed, the switches 22, 23 ‘cause that occurrence to be recorded in the internal memory of the monitor’”).
