    “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. Cir. 2022) (construction of term in independent claims should not render dependent claims superfluous or lacking scope).” slip op. at 20

    “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. 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

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.

    “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.

    “the case law makes clear that “an indefinite article ‘a’ or ‘an’ in patent parlance carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising’” unless an “extremely limited” exception applies. See Convolve, Inc. v. Compaq Computer Corp., 812 F.3d 1313, 1321 (Fed. Cir. 2016) (quoting KCJ Corp., 223 F.3d at 1356; Baldwin Graphic Sys., Inc. v. Siebert, Inc., 512 F.3d 1338, 1342 (Fed. Cir. 2008)). Here, claim 1 recites the transitional phrase “comprising,” meaning it is open-ended, and, therefore, the usual meaning of “a” as “one or more” would have been expected absent an extremely limited exception. In considering whether an exception applies, our review of the ’515 patent fails to indicate that the patentee intended the phrase to mean anything other than the usual meaning of “one or more.” Patent Owner asserts that “[t]he plain language of the claim clearly indicates only a single [list] is used to list multiple assets” and quotes two portions of the Specification, which state “a list of assets that satisfies criteria” and “a list of assets to which a . . . device is granted access.” PO Sur-reply 12–13 (quoting Ex. 1001, 12:60–67) (citing Ex. 1001, 2:23–34, 3:1–5, 4:21–23, 17:59–66). Although claim 1 of the ’515 patent recites “assets” in the plural, we fail to see how that conveys that the term “a” would have been understood as limited to “one.” Notably, neither party has identified any inconsistency, in the claims or other portions of the Specification (including the portions quoted and/or cited by Patent Owner), resulting from construing “a” as “one or more.” And, we find that there is no reason why the claims could not be met under the construction of “a” as “one or more.” Thus, we find that the ’515 patent does not “evince [ ] a clear intent to limit a or an to one.” See Convolve, 812 F.3d at 1321 (internal quotations omitted). Accordingly, we construe the term “a” in “a list of assets” as “one or more” such that the phrase “a list of assets” means “one or more list of assets.” Considering next the phrase “the list of assets” recited in limitation 1[e], the parties do not dispute that the use of the term “the” means that “the list of assets” refers back to the one or more list of assets retrieved in limitation 1[d] and discussed above. See PO Resp. 1–2; see generally Pet. Reply; PO Sur-reply 5. Similarly, the parties do not dispute that the phrase “the filtered list of assets,” recited in limitation 1[e], refers back to the list of assets resulting from the filtering step of limitation 1[d].

First, Petitioner contends “the combination is the use of a known technique to improve similar devices because using the capabilities of a client device to choose appropriately formatted content was a well-known technique.” Id. Petitioner asserts that “implementing Marusi’s techniques for organizing multiple representations and choosing among them based upon a client device’s capabilities would predictably function in Pyle’s system, which similarly seeks to target video content based on particular client device types and parameters.” Id.

Second, Petitioner argues that “detecting a client device’s capabilities based upon client device identifiers was a common and known solution to the problem of supplying information in a format usable by the client device.” Pet. 21. Petitioner contends that one of ordinary skill in the art “would have found it obvious to combine Marusi’s teachings with Pyle because it is one solution, from a finite number of known, and predictable solutions.” Id.

Third, with respect to Marusi’s databases, Petitioner contends “[t]he combination of Marusi’s databases to manage the data in Pyle’s system uses a known technique to improve similar systems.” Pet. 21. In particular, Petitioner asserts that one of ordinary skill “would have been motivated to combine Marusi’s database teachings with Pyle because Pyle teaches storing the same content in multiple, different representations.” Id. at 21–22 (citing Ex. 1004, 9:64–10:21).

Additionally, Dr. Reader opines that one of ordinary skill in the art “would have understood that the teachings of Pyle and Marusi were complementary, and therefore would have been motivated to combine Pyle with Marusi to enhance the efficiency of generating, storing, and delivering multimedia content tailored to the capabilities of particular playback devices.” Ex. 1003 ¶ 150.” slip op. at 27

    “Turning to Petitioner’s video (Ex. 1018), Petitioner asserts testing of commercial versions of the Layfield fairing illustrates what one skilled in the art would have understood from Layfield itself, namely that the Layfield strut is adapted to sustain an elastic deformation when a load is applied to the resilient strut when the skirt panel moves away from the configuration reducing air drag about the trailer and to self-recover the resilient strut original shape when the load is removed. Pet. 29 (citing Ex. 1010 ¶¶ 102–103).16 We afford this evidence little weight for several reasons. First, the video does not show the strut or the bending of a strut. See Ex. 1018. In fact, the only feature shown is a skirt panel attached to a trailer. that because thermoplastic material is more resilient than aluminum, we should adopt Petitioner’s argument. Pet. Reply 15–16 (citing Ex. 1058, 1– 12; Ex. 1010 ¶¶ 77–82). We must base our decision in this case on the arguments and evidence presented. As explained above, the record before us has contradictory evidence in the form of Dr. Micklow’s testimony that was not before the examiner. 16 Petitioner does not cite Exhibit 1018 in the Petition, but instead cites to Mr. Tres’s testimony regarding the exhibit. Id. Thus, from the video, it is unknown whether the skirt panel is attached to the trailer by one strut, multiple struts, or additional features. Second, Petitioner does not identify clearly how the tested system precisely corresponds to the teachings of Layfield. For example, Patent Owner raises a number of issues with the struts and panels in the video to which Petitioner provides either no response or an unconvincing response. For example, Patent Owner argues that each embodiment of Layfield uses trusses 36 to “interconnect each skirt panel and reinforce the panel assembly,” while it is asserted that the skirt panels in the video do not have trusses and are not interconnected. PO Resp. 26. Petitioner argues that the skirt panels in the video were made according to the teachings of Layfield and did include “integral vertical lateral side edges as the connecting mechanism for adjacent panels.” Pet. Reply 19 (citing Exs. 1018, 2003, 2005; Ex. 1004, 18:36–39; Ex. 1010 ¶¶ 63–64; Ex. 1055 ¶¶ 37–38). Other than stating that the skirt panels have connecting mechanisms, Petitioner does not address the fact that the panels are not interconnected according to the teachings of Layfield, as Patent Owner correctly pointed out.

    “components (see, e.g., id. at 17:1–10), Layfield does not contain any express disclosure concerning the flexibility of the struts. Nor does Layfield include any discussion about the desirability of strut flexibility. The closest Layfield comes to discussing flexibility of the struts is by frequently referring to the struts as “support struts” (see, e.g., id. at 18:40) and discussing the use of a “bracket means,” which is on the struts, to “rigidly secure” the skirt panels to the trailer (id. at 6:48–49). Further, Layfield’s detailed discussion of the embodiment of support strut 58 shown in Figure 10, reproduced below, highlights the bracing and reinforcement features. Figure 10, above, shows the construction detail of a support strut 58. Ex. 1004, 15:45. Specifically, Layfield discloses that strut 58 includes “a pair of spaced-apart vertical members 160, which are braced by horizontal cross-members 162” and “reinforcing rectangular lattice 170.” Id. at 15:46– 54. Thus, we agree with Patent Owner’s argument that “Layfield does not expressly teach that the ‘support struts 58’ are ‘resilient.’” PO Resp. 42 (citing Ex. 2001 ¶¶ 148–149). We reiterate that Petitioner’s first challenge is based on anticipation. Thus, Petitioner must show that resilient struts are “either expressly or inherently described, in” Layfield. Verdegaal Bros. Inc., 814 F.2d at 631; see also PO Resp. 42. In its Reply Brief and at the oral hearing, Petitioner contends that its challenge is based on express disclosure, not inherency. See Pet. Reply 17–18; Tr. 9:21–11:4 (arguing that “this is not a case of inherency”). Petitioner contends one of ordinary skill in the art “would have understood, based upon Layfield’s express disclosures concerning the material, structure, and connection of the strut, that the Layfield strut is resilient and can sustain significant and substantial elastic deformation.” Pet. Reply 18 (citing REG Synthetic Fuels, LLC v. Neste Oil Oyj, 841 F.3d 954, 960–61 (Fed. Cir. 2016)). Whether we analyze Petitioner’s argument based on express disclosure or inherency, we reach the same result. To begin, although we agree with Petitioner that a prior art reference “need not satisfy an ipsissimis verbis test” (Pet. Reply 17 (quoting In re Gleave, 560 F.3d 1331, 1334 (Fed. Cir. 2009))), there is no express statement that Layfield’s strut is resilient or otherwise exhibits a characteristic synonymous with resiliency. Additionally, we do not agree that Petitioner’s reliance on the thermoplastic materials, disclosed by Layfield for construction of the strut, establishes whether the strut is resilient and capable of elastic deformation. The evidence submitted by the parties is contradictory as to whether one of ordinary skill in the art would have understood Layfield’s struts to be resilient based on the material alone.15 Compare Ex. 1010 ¶¶ 74–82 15 Petitioner also points to a finding by the examiner, during prosecution of the ’017 patent application, that an aluminum strut was resilient, and argues (Mr. Tres opining as to the materials disclosed by Layfield), with Ex. 2001 ¶¶ 160–164 (Dr. Micklow contradicting Mr. Tres’s testimony regarding the materials disclosed by Layfield). Further, the evidence is contradictory as to whether one of ordinary skill in the art would have understood from the design of Layfield’s strut, specifically the taper design and mechanism by which the strut connects to the trailer I-beam, that the strut is resilient. Compare Ex. 1010 ¶¶ 83–90 (Mr. Tres’s testimony regarding the design and connection mechanism), with Ex. 2001 ¶¶ 165–175 (Dr. Micklow’s contradictory testimony). Turning to Petitioner’s video (Ex. 1018), Petitioner asserts testing of commercial versions of the Layfield fairing illustrates what one skilled in the art would have understood from Layfield itself, namely that the Layfield strut is adapted to sustain an elastic deformation when a load is applied to the resilient strut when the skirt panel moves away from the configuration reducing air drag about the trailer and to self-recover the resilient strut original shape when the load is removed. Pet. 29 (citing Ex. 1010 ¶¶ 102–103).16 We afford this evidence little weight for several reasons. First, the video does not show the strut or the bending of a strut. See Ex. 1018.

    “Additionally, Patent Owner similarly contends that the modifications proposed are redundant of Layfield’s “flexible lower panel 20,” which already “allow[s] flexing when impacting a road object.” PO Resp. 59 (citing Ex. 1004, 14:13–18); see PO Sur-reply 26–27. We disagree. Again, the proposed modifications here are to Layfield’s struts. In the context of Petitioner’s anticipation challenge, we agreed with Patent Owner and found that Petitioner had not established sufficiently on the record that Layfield’s struts were resilient. See supra, § II.D.a.i., ii. Therefore, the proposed modification addressed here, to make Layfield’s struts resilient, does not duplicate the objective of Layfield’s flexible lower panel 20 at least because (a) Layfield’s struts are a different structure than lower panel 20 and (b) modification of Layfield’s struts would provide greater impact protection to other panels aside from just lower panel 20. See Pet. Reply 26–27 (One of ordinary skill in the art “would have been motivated to do so because Rinard and Layfield both seek to provide fairing panels with ‘sufficient flexibility’ to bend when encountering objects.” (citing Ex. 1004, 12:67– 13:4; Ex. 1006, 10:43–50; Ex. 1055 ¶ 47)). We determine that Petitioner has shown that one of ordinary skill in the art would have had a reason with rational underpinning to look to other similar types of trailer components that are flexible to make further improvements to Layfield’s design. See KSR, 550 U.S. at 417 (“[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.”). Third, Patent Owner contends one of ordinary skill in the art “would not have a reasonable expectation of success at achieving the claimed technology by looking to the vertical supports of Rinard’s air scoops to modify the Layfield skirt panels 10 and support struts 58.” PO Resp. 61 (citing Ex. 2001 ¶¶ 237–240). Patent Owner asserts that because Layfield’s upper skirt panels are rigid and non-moving one of ordinary skill in the art “would not reasonably expect the hypothetical modified panels (with their reinforcing trusses 36) to move.” Id. Patent Owner also argues that Rinard teaches “an upper skirt panel that is rigid and non-moving” and so it is not reasonable to expect modifying Layfield as proposed would somehow cause Layfield’s fixed skirt panels to be able to move as claimed. PO Sur-reply 27–28 (citations omitted). We disagree for the same reasons discussed above—namely, we find Layfield’s upper skirt panels to be resilient. Therefore, one of ordinary skill in the art would have a reasonable expectation of success in achieving a resilient strut adapted as claimed by modifying Layfield’s strut in light of Rinard, for the reasons proposed by Petitioner. See Pet. Reply 27 (“Applying this solution to the Layfield skirt panel and struts would yield the predictable result of allowing the Layfield skirt panel 10 and struts 58 to absorb greater impacts without having to be repaired or replaced.” (citing Ex. 1021, 7–8, 11–12)).” slip op. at 42
