  • 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

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

The Federal Circuit stated that substantial evidence only supports the conclusion that a POSA would have been motivated to combine the teachings of Kumada and Debladis ’120.

The evidence of record, including the ’892 patent and its prosecution history,9 indicates that the ordinary and customary meaning of “transitioning . . . from . . . to” encompasses both direct and indirect transitions. Looking first to the claim language itself, the word “directly” appears in claims 1, 6, and 10, but not claim 14, presumptively suggesting that claim 14 was intended to more broadly capture systems with either direct or indirect transitions.

The independent claims employ “comprising” language and could allow, for example, for the caching of packets, after the signal to process packets in accordance with the second rule set has been received, even if the swapping of rule sets has not yet occurred. Patent Owner’s construction attempts to incorporate other aspects of the claims into a single limitation that is not so limited under its plain and ordinary meaning.

We are persuaded, however, that Roese, Huima and Hayter teach, as proposed by Petitioner, the caching of at least some portion of a packet while rule sets are being swapped. the rapid response identifier signal is received, the response system initiates the process of configuring the forwarding engine with the one or more policies and/or PERs, and Huima teaches that in response to receiving a signal to change the rule set, packet processing pauses.

Additional education may substitute for experience, and significant work experience may substitute for formal education. Pet. 6 (citing Ex. 1002 ¶¶ 115–120). Patent Owner does not dispute Petitioner’s proposed level of skill in the art, which is consistent with the prior art references asserted by Petitioner. Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001) (stating that the applied prior art may reflect an appropriate level of skill).

    “Since the parties apply what they contend is the plain and ordinary meaning of the claim terms in their briefs, and have stipulated in the Cox case that the plain and ordinary meaning applies, and Patent Owner argues that the district court’s construction in the Charter case is the plain and ordinary meaning, there is no controversy concerning claim terms that we need to resolve in this Decision. Pet. 6; Prelim. Resp. 10; Ex. 1005, 104–105; Ex. 2001, 2. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). At this stage of the proceeding, therefore, we apply the plain and ordinary meaning to the claim terms consistent with their ordinary and customary meaning under 37 C.F.R. § 42.100(b). We note, however, that Patent Owner seems to consider the court’s construction in the Charter case to require that the claimed “probe” must be of a type that can be compared with a reference signal. Prelim. Resp. 10. We question whether all of the different types of probes mentioned and claimed in the ’690 patent would require comparison with a reference signal. See, e.g., Ex. 1001, 2:7–19. However, this is a matter best resolved, if necessary, on a full record at trial.” slip op. at 14

    “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). Patent Owner asserts that the portions of IEEE-802.16 that Petitioner cites do not disclose that the ranging code index is sent as part of a ranging request message. Prelim. Resp. 25. 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

Level of Skill in the Art Petitioner, relying on the testimony of Mr. Lipoff, contends that a person of ordinary skill in the art “would have had a Bachelor’s Degree in electrical engineering, computer science or a related field, and at least two years of experience with voice interfaces and information processing,” and that “[m]ore education could substitute for less experience, and vice versa.” 5 The complete record does not include allegations or evidence of objective indicia of nonobviousness. same proposal.

    “From this description in Burrows, it is clear that index 70 has no sense of ranking, and that Burrows’ system overall has no sense of ranking prior to a query; thus, adding or deleting a webpage from the index does not change a ranking that does not yet exist. It is also clear that, if a page is flagged as deleted, it will be ignored by the query module when the query module queries the index and ranks the identified qualified pages. Id. at 15:12–16, 15:21–22. The webpage’s rank is not decreased, as the webpage is never ranked in the first place. As Mr. Occhiogrosso testifies: web page. A “polled web site” page cannot be ranked in the Burrows system because the Burrows ranking is performed only after a user query is performed. Only at that time can the Burrows system provide a ranked list (of qualified webpages) for presentation to the user. As Burrows discloses, the Automated Web Browser is robotic in nature and not associated with the queries of users. Ex. 2009 ¶ 181. Mr. Occhiogrosso’s testimony on this point is consistent with Burrows’ description, credible, and entitled to substantial weight. We have considered Mr. Lipoff’s testimony that a skilled artisan “would have understood that combining Burrows’s polling mechanism receiving no response into Kovatch would decrease the entries’ ranking or placement in Kovatch’s destination tree in order to further limit the pages that may not be of interest to the user.” Ex. 1002 ¶ 172 (citing Ex. 1006, 1:38–46). That testimony, however, is conclusory and lacks persuasive reasoning. Moreover, the passage in Burrows to which it cites (Ex. 1006, 1:38–46) does not teach or suggest decreasing the ranking of webpages. Thus, Mr. Lipoff’s testimony on this point lacks credibility and is entitled to little weight. Upon consideration of the complete record, we are not persuaded that Kovatch and Burrows teach claim limitations 1H and 2H.” slip op. at 22

    “In the Reply, Petitioner argues that “the type of database record that Burrows polls and ranks makes no difference for this teaching; processing costs and cycles, equating to processing time, are a potential issue any time computer processing occurs.” Reply 20 (citing Ex. 1061 ¶ 24). Mr. Lipoff repeats this statement in his testimony without identifying the basis for it, rendering that testimony of little value. Ex. 1061 ¶ 24. In any case, it appears that Petitioner and Mr. Lippoff are arguing that a general notion of processing cost any time computer processing occurs would lead a skilled artisan to decrease a webpage’s rank based on response time. This is a new argument, not presented in the Petition, and is therefore forfeited and will not be considered. In any case, Petitioner has not supported this new argument with persuasive evidence.” slip op. at 31

    “In sum, for several reasons, Petitioner has not shown that Kovatch and Burrows teach claim limitations 1H–1J and 2H–2J and, therefore, Petitioner has not shown that Kovatch and Burrows teach each limitation of claims 1 and 2. 4. Conclusion of Nonobviousness As explained above, Petitioner has failed to show that the combination of Kovatch and Burrows teaches each limitation of claims 1 and 2. Upon consideration of all the evidence, we conclude that Petitioner has not proved by a preponderance of the evidence that claims 1 and 2 would have been obvious over Kovatch and Burrows.” slip op. at 32

    “Moreover, Petitioner’s proposed combination is sufficient for obviousness even if we accept Patent Owner’s proposed temporal requirement. Specifically, Petitioner’s rationale for adding Abhyanker’s user inputs (i.e., “allowing a user to designate a geographic position of a roof and to subsequently confirm that the roof location is correct would promote the accuracy of the system,” Pet. 24, 67 (emphasis added, Petitioner’s emphasis omitted)), explains why one skilled in the art would have provided Abhyanker’s lock pushpin option after placing a marker. See also Ex. 1003 ¶¶ 43, 127. Patent Owner’s argument, in contrast, assumes a skilled artisan could do no more than bodily incorporate Abhyanker’s placement and lock features without any thought as to sequence. That, however, is not the test for obviousness. See, e.g., Allied Erecting & Dismantling Co. v. Genesis Attachments, LLC, 825 F.3d 1373, 1381 (Fed. Cir. 2016); see also KSR Int’l Co. v.

For these reasons, and in light of the Petition’s analysis, see Pet. 24– 25, 33–35, 67, 74, we agree with Petitioner that its proposed combination teaches “responsive to receiving the designation of the building roof structure location, providing a second computer input capable of signaling user-acceptance of the building roof structure location within the first image, wherein user-acceptance is one or more affirmative steps undertaken by the user to confirm the designation of the building roof structure location,” as claimed.6” slip op. at 11

  • 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

  • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)UnpatentableUnpatentable

    “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). There is no dispute that Mr. Teater meets this standard.
