    “In order to determine whether an invention would have been obvious at the time the application was filed, we consider the level of ordinary skill in the pertinent art. Graham, 383 U.S. at 17. 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. Cir. 1995) (quotation omitted). Petitioner contends a person of ordinary skill in the art “would have possessed at least a four-year degree in electrical engineering, chemical engineering, physics, or material science, or a closely related field, and at least two years of experience in semiconductor device design or fabrication, including the processing of semiconductor materials, analysis of device operation, or the development of new device topologies.” Pet. 5–6. Petitioner contends “[a]dditional education could substitute for professional experience and vice versa.” Id. at 6. Patent Owner contends that a person of ordinary skill in the art would have had “at least a four-year degree in electrical engineering, physics, material science, or a closely related field, and three years of professional work experience in the epitaxial growth, design, and fabrication of semiconductor electronic devices, including those of GaN.” PO Resp. 7 (citing Ex. 2009 ¶ 82). Upon review of the evidence of record and the parties’ arguments, we adopt Petitioner’s definition of the person of ordinary skill in the art as it is consistent with the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (holding that the prior art itself can reflect the appropriate level of ordinary skill in the art).

See Ex. 2009 ¶ 83 (Dr. Schubert testifying that his opinions would be the same under either proposed definition); Ex. 1033 ¶ 9 (Dr. Shealy testifying that the differences in proposed definitions of the ordinarily skilled artisan “would not change the outcome of the invalidity analysis in any material manner”); PO Resp. 7; Pet.

    “compensated GaN layer above the barrier layer, and a gate contact above the compensated GaN layer.” Ex. 1001, 5:12–18. Petitioner contends the term “compensated” indicates that the step of compensating the GaN layer has already occurred, such that the term “compensated GaN layer” should be construed as a “‘[d]oped GaN layer formed with a step to passivate its impurities’ which is a ‘product-by-process’ limitation.”5 Pet. 12–14. And, because compensation with hydrogen was the “critical step” distinguishing the claims from the prior art, and because hydrogenation in as-grown III-nitride materials had been well known for over a decade by 2009, Petitioner contends “compensated” “cannot be interpreted as mere hydrogen presence in as-grown material, a well-known property of doped GaN.” Id. at 15. Patent Owner contends “compensated GaN material” should be construed as “a semiconductor GaN gate material in which one type of impurity (for example, donor) cancels the electrical effects of the other type of impurity (for example, acceptor).” PO Resp. 11 (citing Ex. 2009 ¶ 92) (emphasis added). Patent Owner contends this construction is consistent with the IEEE dictionary, which defines “compensated semiconductor” as 5 Given that product-by-process steps in a device claim are not entitled to patentable weight, Petitioner contends “the prior art only need show a material with passivated impurities to show unpatentability, not the step to achieve it.” Pet. 15–16. “[a] semiconductor in which one type of impurity or imperfection (for example, donor) partially cancels the electric effects of the other type of impurity or imperfection (for example, acceptor).” PO Resp. 14 (quoting Ex. 2004). Patent Owner contends its construction is also consistent with the written description of the ’294 patent, which explains that a compensated GaN material is part of the gate and includes a p-type impurity that imparts an electrical effect (i.e., conductivity), as well as a second impurity, e.g., hydrogen, that partially cancels the electrical effect of the p-type impurity, rendering the layer semi-insulating. Id. at 14–15 (citing Ex. 1001, 3:10–13, 3:43–45). On this record, we construe “compensated GaN layer” as “a GaN layer in which one type of impurity (for example, donor) partially cancels the electric effects of the other type of impurity (for example, acceptor).” This is consistent with the disclosures of the ’294 patent, the IEEE dictionary definition, and the construction ultimately adopted by the ITC. Ex. 2004, 3; Ex. 1049, 16–17 (ITC construing “compensated GaN layer” to mean “a GaN layer in which one type of impurity partially cancels the electrical effects of another type of impurity”); Ex. 1001, 3:43–45 (explaining that the compensated GaN layer of the ’294 patent is formed through the “passivation of a p-type impurity using hydrogen”). For the reasons set forth below, however, we decline to construe “compensated GaN layer” as a product-by-process claim term (as asserted by Petitioner), or to limit the compensated GaN layer to a gate material (as asserted by Patent Owner).” slip op. at 11

  • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner

    “There are two exceptions to the general rule that we apply the ordinary and customary meaning of a claim term: (1) when a patentee sets out a definition and acts as his own lexicographer, or (2) when the patentee disavows the full scope of a claim term either in the specification or during prosecution. See Thorner, 669 F.3d at 1365. The standards for lexicography and disclaimer, however, are “exacting.” Id. at 1366. There is no argument that the patentees acted as their own lexicographer to redefine the term “compensated GaN layer.” With respect to disavowal, a “patentee may demonstrate intent to deviate from the ordinary and accustomed meaning of a claim term by including in the specification expressions of manifest exclusion or restriction, representing a clear disavowal of claim scope.” Thorner, 669 F.3d at 1366 (quoting Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1325 (Fed. Cir. 2002)). As noted by Patent Owner, the title of the ’294 patent is, in part, “Compensated Gate MISFET” and much of the discussion of the ’294 patent is of a compensated GaN layer that is directly below the gate contact and above a barrier layer and operates in conjunction with the gate contact to control the on/off state of the transistor. PO Resp. 12–14. We are presented with insufficient argument or evidence to conclude, however, that these disclosures rise to the level of a disclaimer. For example, although the title of the ’294 patent is directed to a “Compensated Gate MISFET,” claim 1 is more broadly directed to “[a] column III Nitride transistor.” Ex. 1001, 5:12, code (54). Nor are we directed to an expression or statement of manifest exclusion in the ’294 patent that would serve to disclaim any “compensated GaN layer” that is not directly below the gate and/or that does not function in concert with the gate electrode to control the on/off state of the transistor. See Thorner, 669 F.3d at 1366. With respect to the stated goals of the invention, as noted by Patent Owner, one of the primary purposes of the compensated GaN layer of the ’294 patent is to reduce gate leakage and gate capacitance. Ex. 1001, 2:13– 19, 3:18–21 (“[U]sing a compensated semiconductor layer 38 leads to low gate leakage during device operation.”). We cannot use the goals of the invention, however, to rewrite the claims or insert terms that are not present. See Thorner, 669 F.3d at 1366. Moreover, the prior art of record indicates that a compensated GaN layer that is below the gate contact and above a barrier layer, but not part of the active gate structure, may also “decrease the leakage current between the gate and the drain.” Ex. 1006 ¶¶ 44 (“Even when a positive bias of 5 V or higher is applied to the gate electrode, no significant gate-leakage current is observed.”), 61. As such, evidence of record suggests that a person of ordinary skill in the art would have understood that one of the primary goals disclosed in the ’294 patent is achieved regardless of whether the compensated GaN layer is part of the gate, or simply in close vicinity to the gate. In view of the foregoing, we are not persuaded that the written description of the ’294 patent indicates that the “compensated GaN layer” must be part of the gate structure.” slip op. at 17

  • Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for petitioner

    “To be probative, Patent Owner must prove there is a nexus between the presented evidence and the merits of the claimed invention. See Demaco Corp. v. F. Von Langsdorff Licensing Ltd., 851 F.2d 1387, 1392 (Fed. Cir. 1988). A rebuttable presumption of nexus applies when the “patentee shows that the asserted evidence is tied to a specific product and that the product ‘is the invention disclosed and claimed.’” Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (quoting Demaco, 851 F.2d at 1392). “That is, presuming nexus is appropriate ‘when the patentee shows that the asserted objective evidence is tied to a specific product and that product embodies the claimed features, and is coextensive with them.’” Id. (quoting Polaris Indus., Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1072 (Fed. Cir. 2018)). If the praise is not limited to the features of the claimed invention, the patent owner may still prove nexus “by showing that the evidence of secondary considerations is the ‘direct result of the unique characteristics of the claimed invention.’” Id. at 1373–74 (quoting In re Huang, 100 F.3d 135, 140 (Fed. Cir. 1996)). Patent Owner contends that the compensated gate of the ’294 patent “was a breakthrough invention and resulted in the first commercially viable enhancement-mode GaN transistor.” PO Resp. 60 (citing Ex. 2009 ¶¶ 192– 193, 197; Ex. 2021). Patent Owner further contends that this achievement required the counter-intuitive use of a compensated gate material in the gate structure, and represented “a technological leap that laid the foundation for viable enhancement-mode GaN transistors.” Id. at 61–62. For this achievement, Patent Owner contends the inventor, Dr. Alex Lidow, received the 2015 SEMI Award. Id. at 60 (citing Ex. 2021). Upon review of Patent Owner’s evidence and the parties’ arguments, we find that Patent Owner’s objective indicia evidence is entitled to little, if any, weight. The evidence of praise relied upon by Patent Owner is not clearly linked to the claimed invention or any particular product having each of the claimed features of the ’294 patent. Ex. 2021. For example, the 2015 SEMI award was provided to Dr. Lidow “for commercialization of GaN power devices.” Id. An article explaining the award indicates that “high cost” previously “limited [the] commercial success” of GaN technologies, but Dr. Lidow was able to overcome these issues, “from resolving packaging limitations to establishing a low-cost supply chain,” “through persistence.” Id. This praise is not demonstrably linked to the claimed invention or any particular device, and does not mention the use of a compensated gate, or any other relevant feature recited in the claims. In view of the foregoing, we determine that Patent Owner’s objective evidence of non-obviousness is entitled to little, if any, weight.” slip op. at 20

    “We find that Holmberg expressly contemplates using its wall box within multi-dwelling units, notes that multi-dwelling wall boxes in the prior art were “typically provided” on every floor, and discloses that the multi-dwelling wall boxes would contain optical couplings for each resident on a given floor. Ex. 1004 ¶¶ 7, 34; Pet. Reply 8–10. In view of these disclosures, we credit the testimony of Dr. Kiaei that one of ordinary skill in the art would have sought to use Holmberg’s wall box in multi-dwelling units and would have seen a need to access the area behind spice tray 230 to connect and disconnect subscribers. Ex. 1003 ¶ 92; Ex. 1033 ¶¶ 7–8. Moreover, even if Holmberg were limited to mid-span locations and distributing drop cables, as opposed to distribution cables for individual subscribers, as asserted by Patent Owner, Patent Owner does not dispute that a technician would still need periodic access to the area behind splice tray 230 in these mid-span devices. Tr. 38:3–39:1 (counsel agreeing that one would need to access the area behind splice tray 230 in Holmberg, albeit in “rare occasions”); Ex. 1003 ¶¶ 90–92; Ex. 1033 ¶¶ 7–8. Thus, whether used in the manner contemplated by Petitioner or Patent Owner, Petitioner persuasively demonstrates that access to the space behind splice tray 230 in Holmberg would be necessary. With access behind splice tray 230 required, Petitioner persuasively demonstrates that one of ordinary skill in the art would have seen a benefit to replacing Holmberg’s fasteners or screws with a hinged connection, such as that disclosed in Battey, to allow easier access to the area behind the splice tray. Pet. 41 (citing Ex. 1005 ¶ 39 (disclosing that a rotatable splice tray or shelf would “provide[] full and convenient access to the splice tray”)). First, Petitioner and Dr. Kiaei persuasively demonstrate that once the fibers of Holmberg are routed from behind splice tray 230 and the distribution cables spooled on this tray, a technician could not reasonably access fiber optic cables stored behind splice tray 230 without releasing or opening splice tray 230. Pet. Reply 14–15 (citing Ex. 1023, 60:20–61:15); Ex. 1033 ¶¶ 31–32. Second, Petitioner persuasively demonstrates that without a hinged connection, the technician would have to either hold the splice tray of Holmberg with one hand while performing the necessary routing and splicing steps, two screws would need to remain in place (essentially replicating a hinge), or the tray would have to be left to dangle, supported only by the routed and spliced fibers.

    “art would not have modified Kurita in view of Lemoff because Lemoff positions the signal emitters near the fiber to emulate WDM without the need for an external optical multiplexer or a similar device and discourages using optical wavelength multiplexers for short distances because the complexity of the design is often cost prohibitive (PO Resp. 47–48), Lemoff does not appear to limit the usefulness of the fiber connector to any particular optical signal transmission distance. Petitioner relies upon Lemoff for a suggestion to combine Lemoff’s fiber connector configuration teachings with Kurita’s multiplexer teachings to enable fibers to be plugged Fig. 2) (Pet 29, 31; Reply 17–18). Regarding Patent Owner’s argument that one of ordinary skill in the art would not have combined Lemoff’s receptacle and ferrule with discrete components in Kurita because the fiber would need to be manually fixed and aligned with or without a ferrule and, therefore, would serve no purpose (PO Resp. 48), Lemoff’s fiber connector appears to fix and align the fiber adequately for wavelength division multiplexing without manual fixation or alignment being required (Ex. 1006, 5:65–6:2, Fig. 2; Reply 18). The challenged claims do not require any greater degree of fixing and alignment than that provided by Lemoff’s fiber connector. Regarding Patent Owner argument that Lemoff’s device is not physically combinable with Kurita’s WDM multiplexer due to Lemoff’s device’s small size (PO Resp. 47–48; Reply 17–18), “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference....

Claim 1 requires “focusing means having n separate radial sectors on its surface, and each of said n collimated beams passes through a separate one of said n sectors of said focusing means” (Ex. 1001, 5:34–37), claim 2 requires “four lasers and four collimating lenses are each formed in a two-dimensional, two by two array [centered on the focal axis of lens 30], wherein said focusing means is a single focusing lens, and wherein each radial sector is a pie-shaped quadrant” (id. at 5:41–44), and claim 7 requires “focusing means having four separate quadrants on its surface, and each of said four collimated beams passes through a separate one of said quadrants of said focusing means” (id. at 6:35–38).

    “formation response data comprising data from one or more downhole sensors or surface sensors” and “selecting a representative system model based on the received formation response data and sequence of stimuli” are mental processes. We determine that the record supports that they are. The Background of the ’058 patent supports our finding that these steps are mental processes. In particular, the ’058 patent teaches that it was known that “a technician may review sensor data” and that “a representative system model may be used for determining pump settings based on sensor information; however, the representative system model is typically manually selected by a technician based on observed sensor data.” Id. at 22 (quoting Ex. 1001, 1:9–26); see also Dec. 23–24 (preliminarily finding these claimed patent). Regarding the claimed step of “controlling an electrical fracturing pump based on the representative system model,” Patent Owner does argue, and we agree, that it is not a mental process in that one of ordinary skill in the art would not have performed it in the human mind. PO Resp. 27. We also agree that the Petition does not expressly argue that the step of “generating a sequence of stimuli for application to a well environment” is a mental process. However, the ’058 patent explains that these two steps may be performed via a generic computer. Ex. 1001, 6:6–36, 6:65–7:33, 8:56–9:28. Requiring the use of a computer does not change the focus of the claim away from being directed towards an abstract idea. “[T]he inability for the human mind to perform each claim step does not alone confer patentability.” FairWarning IP, LLC v. Iatric Sys., 839 F.3d 1089, 1098 (Fed.

Maritz Holdings Inc., 986 F.3d 1367, 1377 (Fed. Cir. 2021).” Pet. 97. The Petition cites the Background of the ’058 patent to support its argument that the specification admits that many of the claimed steps were known. Id. at 91. In the oil and gas industry, electric frac pumps are often controlled in order to achieve certain downhole environment responses. However, typically settings are performed manually based on manually appraised information retrieved from the downhole environment. For example, a technician may review sensor data and, based on experience, adjust various settings such as flow rate, pressure values, chemical compositions, etc., on an electric frac pump. In some cases, a representative system model may be used for determining pump settings based on sensor information; however, the representative system model is typically manually selected by a technician based on observed sensor data. Additionally, the representative system model may be a static construct and may not accurately reflect the well to which it has been deployed. Ex. 1001, 1:9–26 (emphasis added). From the above, it will be understood that much of claim 1 was well-understood, routine, and conventional, whether considered individually or as an ordered combination. The above paragraph makes clear that “controlling an electrical fracturing pump based on the representative system model” was known and conventional. In addition, adjusting settings on an electrical fracturing pump is also how the ’058 patent teaches to generate a sequence of stimuli. Ex. 1001, 2:25–33 (“A given stimulus of the sequence of stimuli can be achieved by adjusting . . . flow rates . . . . In some examples, a sequence can include a various amplitudes (e.g., high, medium, low, etc.).”). Thus, generating a sequence of stimuli is also acknowledged as being known in the Background. See also Dec. 22–23 (preliminarily finding that these limitations were known). Petitioner provides additional argument that other references also show that these limitations were known. See e.g., Pet. 94. However, it is not necessary for us to review these in view of the express acknowledgement of the state of the art in ’058 patent. Based on the record, we determine that claim 1 does not include any specific limitation beyond the judicial exception that is not “well-understood, routine, [and] conventional” in the field.” slip op. at 15

    “Second, Patent Owner and Dr. Howell assert that a person of ordinary skill in the art “would have understood upon reading the second German application that the capsule features described would be intended to be combinable with each of the described embodiments.” PO Resp. 40; Ex. 2017 ¶ 61. But Patent Owner and Dr. Howell do not explain how a barcode could be used in the devices depicted in Figures 16–18, which place the detection means 2.4.2 on the outer circumference of the flange (not its underside) and rely on toothed-rings physically interacting with either the chamber, retaining arms, or a pinion. Ex. 1047, 12:22–31, 13:8–18. Indeed, the second German priority application explains that means 2.4.2 physically interacts with retaining arms 30 (embodiments of Figures 16 and 17) or a pinon (embodiment of Figure 18), and if means 2.4.2 were not present in these embodiments the capsule would either “drop through into a waste container” or could not be inserted through the insertion shaft. Id. at 12:22– 27, 13:9–12, 13:16–35 (noting that in the embodiment disclosed in Figure 18 a pinon interacts with means 2.4.2 and only when means 2.4.2 “is formed complementary to the teeth of the means” can the capsule be inserted). At no point does the second German application identify means 2.4.2 as a barcode or suggest a barcode could be used as the detection means. The second German application also states that A person skilled in the art is also aware that for example the insertion shaft may also contain a sensor, for example a camera, clear, however, that element 27 is part of the brewing chamber, and not the capsule. Ex. 1047, 12:27–31, 13:5–8, 13:21–26, 15:36. Thus, we are not persuaded that the toothed ring is in fact on the bottom side of the flange. which senses the shape of the means 2.4.2. For example, it would be possible, in the present case, for the shape of the teeth and/or the spacing between the same to be sensed. This signal, in turn, is passed to a control means, which frees, for example, the brewing chamber if the capsule is the correct one. Ex. 1047, 14:11–19. Again, despite using a camera to determine if a capsule is “the correct one,” the second German application does not suggest using a barcode in place of the toothed-ring structure, or suggest moving the location of the detection means 2.4.2 from the outer surface to the underside of the flange. This reinforces that the inventors did not contemplate using a barcode in the embodiments depicted in Figures 16–18.” slip op. at 23

Conversely, Dr. Howle has limited experience in this field and is not one of ordinary skill in the art. Although Mr. Jobin’s testimony is more persuasive regardless of the discrepancy in experience between the two declarants, when this difference in design experience is considered, it only serves to increase the weight we give to Mr. Jobin’s testimony. there is a “snug fit” to avoid “unbalances.” PO Sur-reply 8 (citing Ex. 1004 ¶¶ 205, 479, 484, 507, 512).

Patent Owner’s assertion that Yoakim discloses the use of certain capsules that might not fit into a device with Jarisch’s non-flared structure is ineffective to undercut the sufficiency of Petitioner’s showing on this point.

Tools Inc. v. Int’l Trade Comm’n, 22 F.4th 1369, 1376–78 (Fed. Cir. 2022). The Federal Circuit has made plain that, “[t]o offer expert testimony from the perspective of a skilled artisan in a patent case,” including the issue of patent “validity,” the “witness must at least have ordinary skill in the art.” 12 To be clear, we are not saying that a witness supplying expert opinions must have satisfied the requirements of the level of ordinary skill in the art on or before the priority date of the challenged patent, which Patent Owner seems to understand.

Patent Owner’s view that Yoakim discloses the use of certain capsules which might not fit into a device with Jarisch’s non-flared structure is ineffective to undercut the sufficiency of Petitioner’s showing on this point.

Dr. Akl testifies that [i]f the relationship number was split into a separate transmission[] and transmitted faster than the call itself, as the Petition appears to suggest, then the relationship number could arrive before the call. In this case, the handset would have a notification relating to a call that is not ready to accept, which would be a bad experience for the user because the user would be able to see the incoming call notification but would be unable to accept it. Ex. 2010 ¶ 81. But this testimony ignores the fact that the scenario discussed in Backhaus is the case where a third party caller calls for the first time, and a relationship number is created. See Ex. 1005 ¶ 53. If the pre-call information arrives before the call, then the SLS module on the phone can use the information to display the caller information once the call is connected. Such an approach may avoid the situation where “unknown caller” needs to be displayed, for example. See id. ¶ 55. Indeed, Backhaus suggests Petitioner’s proposed use. See id. ¶ 73 (“Such channels can be used in setting up the relationship databases, sharing information between the SLS module 105 and the SLS platform 115.”). Because Dr. Akl’s testimony is inconsistent with Backhaus’s express teachings, we give it little weight.” slip op. at 42

    “time “would have had an undergraduate degree in electrical engineering, computer engineering, computer science or a related field along with two years of work experience in the field of telecommunication. . . . More education can supplement practical experience and vice versa.” Pet. 4–5 (citing Ex. 1002 ¶¶ 17–18). Patent Owner does not dispute Petitioner’s assessment of the level of ordinary skill. PO Resp. 6. Determining the level of ordinary skill in the art involves various factors, 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. Cir. 1995) (citation omitted). The prior art of record also reflects the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Based on the complete trial record, we adopt the assessment offered by Petitioner and undisputed by Patent Owner, as it is consistent with the ’105 patent and the asserted prior art.” slip op. at 7

    “the term, and invited further briefing. Dec. on Inst. 14–15. Patent Owner does not assert that this construction affects Petitioner’s “first way” obviousness assertions. PO Resp. 31. After consideration of the post- Institution briefing, we agree with Patent Owner that Petitioner’s “second way” obviousness assertions rely upon a lack of ordering in claims 1 and 2 such that the transmitting of pre-call information may occur prior to the receiving on an incoming call (Pet. Reply 3); therefore, the term “pre-call information” requires construction to resolve the controversy. The “general rule [is that], ‘[u]nless the steps of a method [claim] actually recite an order, the steps are not ordinarily construed to require one.’” Mformation Techs., Inc. v. Research In Motion Ltd., 764 F.3d 1392, 1398 (Fed. Cir. 2014). As discussed above, we do not find the asserted information having a bridge number be transmitted after a call to a secondary number is made. The plain language of the claim requires that the pre-call information include a bridge number “for connecting the handset to the incoming call at the switch”; i.e., information to be used with respect to the incoming call recited in limitation [1.d]. The transmission of the pre-call information may therefore be at any time such that its contents (the bridge number) may be used with respect to the recited incoming call. Consequently, we do not adopt Patent Owner’s proffered construction.” slip op. at 13

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundUnpatentable

    “whether teachings other than Winbladh would be preferentially considered, improperly frame the obviousness question. Patent Owner and Dr. Akl emphasize that Winbladh uses a “‘host resource’ that manages multiple call legs,” arguing that is different from Backhaus’s “more limited” system that uses a “conventional call routing system.” PO Resp. 36–37 (citing Ex. 2010 ¶ 113). However, the obviousness question is “whether the relevant artisan would be motivated to make the combination to arrive at the claims’ actual limitations,” not whether such a combination would preserve all aspects of either Backhaus or Winbladh. See Axionics, Inc. v. Medtronic, Inc., 2023 WL 4410686 (Fed. Cir. July 10, 2023). Moreover, “it’s not necessary to show that a combination is ‘the best option, only that it be a suitable option.” Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021) (quoting PAR Pharm., Inc. v. TWI Pharms, Inc., 773 F.3d 1186, 1197–98 (Fed. Cir. 2014)). Further, “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference [but rather] what the combined teachings of those references would have suggested to those of ordinary skill in the art.” Facebook, Inc. v. Windy City Innovations, LLC, 973 F.3d 1321, 1343 (Fed. Cir. 2020) (“KSR does not support [the] theory that a person of ordinary skill can only perform combinations of a puzzle element A with a perfectly fitting puzzle element B”). Here, Petitioner’s combination provides for a pre-call transmission of local telephone number #βr, and would logically provide advantage in those situations in which a long distance number was originally used for the connection; i.e., those situations for which Winbladh is purposed. We further note that a combination need not work in all situations for a person having ordinary skill in the art to find it advantageous. See Intel tradeoffs should be weighed when a benefit occurs during only some operating conditions).” slip op. at 39

The portions of the Lin Declaration that we rely on in this Decision are credible because those portions are consistent with and supported by the other evidence of record.

    “Patent Owner proposes construing the term “channel” in all challenged claims to refer to “[a] channel [that] does not have to be fully connected on both ends or actually transmitting a particular type of information to qualify as a channel.” PO Resp. 6. Petitioner asserts that Backhaus teaches transmitting an access telephone number via a data channel in two ways. Pet. 23–29. We rely only on the “second way” for purposes of this Decision. See Section II.D.3; Pet. 26–29. Patent Owner’s proposed construction of the term “channel” does not impact the parties’ dispute about the “second way” that Backhaus teaches transmitting an access telephone number via a data channel. PO Resp. 21–23; PO Sur-reply 11; Tr. 10:2–11, 68:3–24.1 Therefore, we determine that the term “channel” does not require an express construction to resolve the parties’ disputes regarding the asserted grounds of unpatentability.” slip op. at 7

Doing so would have been obvious because Backhaus teaches using its SLS platform with a PSTN, and Taylor provides an interface that allows an external system, such as Backhaus’s SLS platform, to communicate with a PSTN. Pet. 54–56; Ex. 1002 ¶ 101; Ex. 1005 ¶ 32; Ex. 1007 ¶¶ 4, 8.

    “because it is “highly conclusory” and “internally contradictory,” and because Dr. Lin “could not explain his opinions at deposition.” PO Resp. 38–39; PO Sur-reply 15–17. In particular, Patent Owner contends that the Lin Declaration “does not contain any statement of the legal standards the expert understood or was applying, such as standards relating to defining the person of ordinary skill in the art, anticipation, or obviousness,” and Dr. Lin “could not recall whether Petitioner gave him instructions on any legal principle.” PO Resp. 39–40 (citing Ex. 2009, 9:1–11, 14:5–17:6, 23:6–11, 25:3–10, 26:9–22, 33:11–34:1, 34:3–11); PO Sur-reply 16. Patent Owner’s argument is unavailing. We do not rely on the Lin Declaration as evidence of any legal standard or for Dr. Lin’s legal conclusions. Rather, we rely on the Lin Declaration to support our factual determinations regarding the teachings of Backhaus, Saksena, and Taylor, as well as why and how a person of ordinary skill in the art would have combined those teachings. See Sections II.D.3, II.D.6, II.E.1, II.E.2. Thus, irrespective of whether the Lin Declaration discusses a particular legal standard, we do not disregard the entire Lin Declaration.” slip op. at 26
