      “and reliance on Figure 19 do not in any way explain how updating game costs by meter 502 with a new Cost_Table is relevant to a credit multiplier or even a multiplier being varied over time. Ex. 1003 ¶ 155. Considering this evidence, we determine that Petitioner and Mr. Crevelt’s reliance mainly on snippets from Schneier’s “Updating Cost Information protocol” embodiment does not sufficiently explain why or how a person of ordinary skill in the art would have understood updating game cost to encompass varying a multiplier of credits over time. We also note that during his deposition, Mr. Crevelt was given opportunity to clarify his testimony as to Figure 19 and explain the cost updating embodiment in Schneier, and mostly demurred. See Ex. 2004:158:4–182:6. Explaining his reliance on Figure 19, Mr. Crevelt stated: A: And whatever latest price from that updated cost information coming from the central site is -- is variable, it’s variable as time proceed[s].

See, e.g., id. at 160:16–23 (Mr. Crevelt testifying that “we can go from the description of figure 19, which starts at basically the top of column 56 in the Schneier patent, and . . . describes this process in detail of how the information is transferred from one place to the other and updated.”). Mr. Crevelt concludes that Schneier’s description is “complicated,” and from Figure 19 asserts the cost somehow includes a credit multiplier that “could” or “should” change over time. Id. at 158:23– 159:5. Overall, this testimony fails to sufficiently explain or point to persuasive evidence in Schneier as to how or why a person of ordinary skill in the art would have understood that the Figure 19 cost updating embodiment discloses a time-variable multiplier as required in claim 8.” slip op. at 20

      “We decline Patent Owner’s invitation to construe “during a frame” of “independently controlling simultaneous data acquisition with each of the first and second channels during a frame” by importing the extraneous limitations “at some point between the beginning and the end of the exposure interval during which the image sensors capture a single image.” As pointed out by Petitioner, Patent Owner’s proposed construction is unsupported by the language of claim 22 and the ’180 Specification because Specification does not disclose an exposure interval nor suggest “during a frame” is limited to an exposure interval. Patent Owner and its expert Dr. Saber cite only extrinsic evidence (Exs. 2006, 2009) to support its argument that claim 22 should be limited to an “exposure interval during which the image sensors capture a single image.” See PO Resp. 16–17; Ex. 2020 ¶ 64. Similarly, Patent Owner relies only on extrinsic evidence (e.g., Ex. 2011, 1; Ex. 2022, 1; Ex. 2020 ¶ 66) to limit “during” to “at some point between the beginning and the end.” See id. at 18. When considered in the context of claim 22 and the ’180 Patent Specification which do not limit “during a frame” to an exposure interval, we find that we cannot rely on Patent Owner’s citations to extrinsic evidence to yield a reliable construction for “during a frame.” As demonstrated in the analysis below, we need not provide an explicit construction for “during a frame” to resolve the parties’ disputes regarding the merits of the patentability challenges. See Realtime, 912 F.3d at 1375. We apply the ordinary and customary meaning for “during a frame.” To the extent that an explicit identification of the ordinary and customary meaning may aid the understanding of our analysis, consistent with the language of claim 22 and the ’180 Patent Specification, we find that the ordinary and customary meaning for “during a frame” is “during the period of time that data for an image frame is acquired.” See Ex. 1001, code (57), 20:6–24, 25:23–35.” slip op. at 12

      “Owner to show that Labaziewicz is not prior art because the ’180 Patent is entitled to the earliest August 25, 2004, filing date of the ’854 Provisional Application. See Dynamic Drinkware, 800 F.3d at 1379–1380. For a claim in a later-filed application to be entitled to the filing date of an earlier application, the earlier application must provide written description support for the claimed subject matter. Anascape, Ltd. v. Nintendo of Am. Inc., 601 F.3d 1333, 1337 (Fed. Cir. 2010). To satisfy the written description requirement, “a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997); see also VasCath v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed.

Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1352 (Fed. Cir. 2010) (en banc) (“[I]t is the specification itself that must demonstrate possession.”). Patent Owner’s arguments fail to meet this burden of production because, aside from addressing deficiencies of written description support the ’854 Provisional Application provides written description support for all of the limitations of the claimed invention. See PO Resp. 60–64; PO Sur-reply 25–28. Specifically, Patent Owner does not address written description support in the ’854 Provisional Application for “independently controlling simultaneous data acquisition with each of the first and second channels during a frame”––limitation [22.3]––the heart of the parties’ claim construction disputes addressed above in Section II.A. See PO Resp. 60–64; PO Sur-reply 25–27. Accordingly, Patent Owner has not met its burden of production in coming forward with evidence or argument to show possession of the claimed invention in the ’854 Provisional Application. As a result, the burden of production does not shift back to Petitioner, and, therefore, the ’180 Patent is not entitled to the benefit of the August 25, 2004, filing date of the ’854 Provisional Application.” slip op. at 23

      “We construe “during a frame” to mean the period during which data for a single frame of an image is captured. The limitation is satisfied where the per-channel integration time is effectuated during the frame; it does not require that the integration time be re-determined mid-frame, nor does it require actuation of a “charge integration switch.” The specification’s only use of the phrase confirms this reading: “each camera channel is controlled during a frame under an independent integration time.” Ex. 1001, 3:45–50. Consistent with that usage, the specification describes selecting an integration time for each channel and then integrating the photo-signal “within a single frame of data,” and describes placing the charge-integration switch in a state to allow charge to accumulate for the selected period and then transferring the accumulated charge upon completion of the integration period. Id. at 4:51–54, 11:3–18. We decline Patent Owner’s proposal to require in-frame actuation of a charge-integration switch, for the same reason we decline to import that structure into “integration time.” We also decline to read the phrase to require mid-frame re-determination of the integration time, because the patent’s own embodiment selects an integration time and then integrates charge during the frame under that selected time. Ex. 1001, 4:51–54, 11:3– 18. So construed, “during a frame” is not redundant of the independentclaim limitation: it adds that the per-channel control occurs within a single frame (intrascene), as distinct from adjustment from one frame to the next (interscene).” slip op. at 15

      “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.

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. Having decided proper constructions for the disputed terms, we proceed in our analysis to consider the parties’ arguments concerning the challenge grounds. In the following sections, we apply the plain meaning of the claim terms, and as necessary, specify what the plain meanings are.” slip op. at 23

      “C. Level of Ordinary Skill in the Art Petitioner contends as follows: A POSITA8 would have had a bachelor’s degree in electrical engineering, computer engineering, or a similar discipline, and three to four years of experience working in signal processing and/or communication systems/networks. 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. We adopt and apply Petitioner’s proposed skill level because it is consistent with the problems and solutions identified in the ’690 patent and the prior art references asserted by Petitioner. In addition, we find the adopted skill level consistent with the education and experience that a POSITA would have had. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

Patent Owner does not dispute this assessment. PO Resp. 17–18. In determining 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.

      “shaped portion configured to receive the structural component,” “a connection portion,” and “an extension portion,” and that “the extension portion spac[es] the channel-shaped portion from the [connection portion]” and “the channel-shaped portion, the extension portion and the connection portion are rigidly fixed with respect to one another.” Ex. 1001, 12:14–36 (emphases added). Claim 1’s repeated use of “portion[s]” to delineate between the three main elements of the hanger, i.e., channel-shaped portion, connection portion, and extension portion, shows or at least strongly suggests substantial flexibility as to the specific location where one “portion” transitions to another “portion” in the fire wall hanger. Similarly, although claim 1 recites that the “channel-shaped portion” is “configured to receive the structural component,” claim 1 recites no limitation precluding other “portions” of the hanger from also “receiv[ing]” or otherwise contacting the structural component. Patent Owner argues that “channel-shaped portion” should be construed to mean “[the] portion of the hanger that forms a channel configured to receive the structural component.” PO Resp. 19. Petitioner and its expert, Mr. Fennell, agree with this meaning (Pet. Reply 4; Ex. 1046 ¶¶ 16–20), and so do we. Indeed, claim 1 plainly recites this as discussed above. But Patent Owner then urges us to narrow the meaning of “portion” itself such that “channel-shaped portion” requires “all portions of the hanger which directly bound the channel that receives the structural component.” PO Resp. 19 (emphases added). Patent Owner argues the Specification makes this “clear.” Id. (citing Ex. 1001, 2:28–31). Contrary to Patent Owner’s arguments (PO Resp. 19), we find no support in claim 1 to further narrow the interpretation of “portion” in “channel-shaped portion” to mean every portion of the hanger which directly bounds the channel that receives the structural component. See Ex. 1001, 12:14–36 (claim 1). We, like Petitioner, similarly find no support in the Specification or limited prosecution history (see Pet. 5–6), and Patent Owner does not direct us to any, showing that the inventor acted as its own lexicographer or disavowed any claim scope to allot this narrowed interpretation to the subject limitation.

      “Petitioner argues, inter alia, that Yamaguchi teaches a joist hanger with an extension portion defining a space between its back flange and channel-shaped portion, and Bundy teaches to size a space created by an extension portion of its joist hanger to receive two layers of ⅝-inch-thick drywall between its back flange plane and channel-shaped portion. Pet. 16–18 (citing 1003 ¶¶ 75–78; Ex. 1007, 5:16–18, Fig. 1; Ex. 1041 (“Perspective View”; “Usage View”)); see id. at 17–18 (discussing “advantages” of two layers of 5/8" drywall as “fire resistance in a fire separation wall”). Petitioner argues the skilled artisan “would have been motivated to receive drywall between Yamaguchi’s back flange and channel-shaped portion to provide a shielded fire resistant wooden frame wall.” Pet. 18 (citing Ex. 1003 ¶¶ 78–79; Ex. 1007, 2:10–24); see id.

Petitioner concludes: This modification to Yamaguchi would have been nothing more than applying a known technique (Bundy’s spacing a hanger seat from a wall frame by distance sufficient to accommodate two 5/8”-thick-drywall sheets for fire resistance) to a similar device (Yamaguchi’s hanger having a spacing of indeterminate length) to obtain the predictable result of a firewall hanger having a space between its channel-shaped portion and a wall frame large enough for receiving drywall therebetween, thereby “protect[ing] the structural members of a building.” Pet. 18 (citing Ex. 1007, 5:18–20; Ex. 1003 ¶ 80). Petitioner argues the skilled artisan would have had a reasonable expectation of success in modifying Yamaguchi as discussed above, “because doing so would still allow Yamaguchi’s hanger to perform its intended function of securing a joist to a wall.” Pet. 18 (citing Ex. 1041, 1; Ex. 1003 ¶ 81). Petitioner argues, “[r]ecognizing that Yamaguchi’s and Bundy’s hangers are constructed from sheet metal,” the skilled artisan “would have understood how to modify the size of Yamaguchi’s extension portions to accommodate two layers of 5/8”-thick-drywall while still allowing Yamaguchi’s hanger to secure a joist’s end to a frame wall.” Pet. 18–19 (citing Ex. 1003 ¶¶ 81–83; Ex. 1007, 4:47–51); see id. at 19–20 (discussing that although “Yamaguchi’s described setting is a sill plate,” the skilled artisan “would have been motivated to use Yamaguchi’s hanger on a wood frame wall in particular so that sheathing could be installed in the space behind the joist as taught by Bundy” (citing Ex. 1003 ¶¶ 81–82)).

Petitioner’s arguments to the contrary depend wholly on its proposed interpretation of the term “engaging” (Pet. 58–60; Pet. Reply 30–31), which we reject, as discussed above. Although Yamaguchi (and Cullen and Adams) may teach extension flanges in opposed, face-to-face relation, Petitioner does not explain, let alone with particularity or persuasively, how Yamaguchi’s (or Cullen’s or Adams’) flanges, which would wind up located on opposing sides of a joist (where a joist is mounted in the hanger), also teach such extension flanges engaging each other along a juncture—indeed, what juncture? See PO Sur-reply 7 (“Beyond asserting that the word ‘engaging’—standing alone—does not require ‘touching contact,’ [Petitioner] still does not address how the extension flanges of Yamaguchi, Cullen, and Adams can be said to ‘engage’ each other.”).

On its face, this limitation requires not only that the first and second extension flanges “engage” each other, but also do so “along a juncture.” This recitation of the flanges “engaging” each other along a “juncture” (i.e., a place where things join) strongly supports interpreting the subject limitation to require physical contact (i.e., touching) at least along some portion of the flanges (such as shown in Figure 2, reproduced above). To the contrary, nothing in claims 38 or 91, or their underlying independent claims, suggests that two flanges “engaging each other along a juncture” means or even includes within its scope two flanges “symmetrical to each other across a juncture,” as urged by Petitioner (Pet. 59).” slip op. at 67

To the contrary, Petitioner’s expert, Mr. Fennell, persuasively testifies in detail how and why the skilled artisan would have combined the teachings and suggestions of Yamaguchi and Bundy to achieve the invention of claim 1, including the features of limitation 1.3.B. See, e.g., Ex. 1003 ¶¶ 73–83, 96; Ex. 1046 ¶¶ 30–40. We find Mr. Fennell’s testimony credible (and uncontroverted).” slip op. at 40

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
