To the contrary, the Specification repeatedly discloses the creation and maintenance of low-pressure zones at or near the catheter apparatus restrictors during the course of treatment.

Actuation of the pump helps to create a low pressure zone in the vicinity of the junction of the jugular vein and the subclavian vein by withdrawing fluid in this region, recirculating it through the pump, and discharging the fluid downstream of this region. Because the outflow of the thoracic and lymphatic ducts is located in this region, the lower pressure will facilitate drainage of lymphatic fluid.”) (emphases added).

“On this record, we find persuasive Dr. Day’s testimony that, “there is no functional difference between the SVC and the IVC that would preclude a catheter from functioning once in the SVC.” Ex. 2006, 73:21–74:5; see also Ex. 1002 ¶ 134 (the “methods of balloon activation and operation are the same regardless of whether the occlusion balloon is placed in the SVC or the IVC”). We likewise find persuasive Dr. Day’s testimony that, “Gelfand’s methods, systems and devices . . . could be used in the SVC without any substantial modification other than the catheter potentially being inserted into a vein upstream of the SVC.” Ex. 1002 ¶¶ 122–126; see also id. ¶¶ 130– 134 (similar testimony specific to element [1e]); Ex. 2006, 93:11–99:16, 71:7–78:15, 86:13–87:19, 88:14–90:9, 97:10–13. But to the extent Gelfand’s device needed to be modified, we find persuasive Dr. Day’s testimony that an Engineer POSA would have found such modifications “routine.” Ex. 2006, 205:8–212:21 (“they’re just different variants or dimensions of the invention”). We, likewise, find persuasive Dr. Garcia’s testimony that “Gelfand discloses occluding the SVC or IVC with a balloon catheter device to reduce blood flow to the heart. Gelfand’s catheter is a type of Swan-Ganz catheter, a commonly used catheter with which I and other clinicians are very familiar, and Gelfand discloses that its catheter can be inserted and placed using conventional techniques.” Ex. 1004 ¶ 60; see also Ex. 1006 ¶¶ 27–31 (Dr. Day’s overview of therapeutic balloon catheters). Referencing Dr. Day’s testimony, Dr. Garcia further states that [f]rom a clinician’s perspective, there would have been no difference in using Gelfand’s device to partially occlude the SVC and in using it to fully occlude the SVC. The device would simply have been inserted percutaneously, advanced so that the balloon is in the SVC, and then operated to inflate the balloon to the inner diameter of the SVC. Id. ¶ 127; see also id. ¶¶ 81–83, 127 (detailed explanation of why one of ordinary skill in the art would know how “to place the occlusion balloon in the SVC as taught by Gelfand”). As further noted by Petitioner, “Garcia explained that Gelfand discloses, and a POSA would know, that a modified Swan-Ganz catheter like Gelfand’s could be inserted via the right internal jugular vein so as to place the occlusion balloon in the SVC.” Reply 17 (citing Ex. 1004 ¶¶ 73–83 (showing modified version of Gelfand’s Figure 1), 136, 145–159; Ex. 2006, 101:8–103:10); see also id. at 18–19 (citing Ex. 1032, 51:19–53:23, 204:4–205:22, 206:10–208:24) (Dr. Brecker’s admissions that diameters of Gelfand’s catheter would allow SVC placement via jugular vein and that placement of Swan-Ganz catheters through the SVC via the right internal jugular vein was known).” slip op. at 50

Considering all the argument and evidence of record, we find that Patent Owner has not overcome the presumption with respect to Kaiser for the reasons set forth on pages 16–19 of Petitioner’s Reply, which we adopt in full and briefly address below. With respect to enablement of Kaiser’s device, we find persuasive Dr. Day’s testimony that no substantial modification of Kaiser’s IVC embodiment would be necessary to deploy it in the SVC. See Ex. 2006, 218:6–220:13; Ex. 1002 ¶ 109 (annotated version of Kaiser’s Fig. 2 showing that the lead/catheter passes through the SVC to reach the IVC). With respect to enablement of Kaiser’s method in the SVC, Dr. Brecker’s analysis also falls short of overcoming the presumption that Kaiser is enabling. Dr. Brecker asserts, for example, that Kaiser also does not describe what pressure differential would need to be created through the use of a flow impedance device in the SVC in order to successfully perform its method using such a device in the SVC, and does not provide any exemplary pressure recordings demonstrating that its method can be successfully performed using a device in the SVC. Ex. 2005 ¶ 110. We find persuasive, however, Petitioner’s argument that Kaiser discloses representative pressure differentials, including an effective pressure differential for occluding the IVC (3 mmHg), which Dr. Brecker could not say would be ineffective for the SVC— but which a Clinician POSA could test, along with other pressure differentials to see what results they produced if the SVC were occluded. Reply 16–17 (citing Ex. 1007, 14:22, Fig. 4 (table showing exemplary hemodynamic data obtained by creating a pressure differential in the inferior vena cava); Ex. 1032, 190:23– 192:3 (Dr. Brecker’s testimony that a Clinician POSA would know how to measure the pressures such as those disclosed in Figure 4), 193:14–194:17 (at least some information could be derived from animal testing)).

- BurdenDecided for patent owner
“As an initial matter, we find Petitioner has insufficiently addressed the issue of inherent anticipation by Dixon (or any other prior art) and has done so in a merely conclusory manner. There is no dispute that Dixon (as well as the other asserted prior art) discloses angiogenic eye disorder treatment using the same drug (aflibercept), at the same dose (2 mg), administered in the same way (intravitreal injection), and administered at the same dosing regimen (an initial, a secondary, and a tertiary dose), as required by all challenged claims. See generally Pet.; Prelim. Resp. Petitioner relies on these facts, and the results of a phase 2 clinical trial that followed a different dosing protocol (one not claimed) to establish that the results limitations of claims 1, 26, and 29 are inherent to the phase 3 clinical trials (VIEW 1 and 2) with a dosing regimen that is claimed. See Pet. 38–39. Petitioner calls the claimed results limitations mere newly discovered results of a known process. Id. (citing Montgomery, 677 F.3d at 1381). As Patent Owner identifies, it is not so simple. The evidence of the results of the VIEW 1 and 2 trials itself (found in the ’572 patent) shows that some, but not all, patients treated with the claimed dosing regimen achieved “a gain in visual acuity” as recited by claim 1, “a gain in visual acuity” that is “as effective” “as monthly administration of 0.5 mg of ranibizumab” as recited by claim 26, or “maintaining visual acuity” “as effective[ly]” “as monthly administration of 0.5 mg of ranibizumab” as recited by claim 29. See Ex. 1001, 13:5–38 (Table 1). As Patent Owner points out, the ’572 patent’s described studies 1 and 2, when following the claimed dosing regimen (2Q8), were not always effective treatments––achieving mere maintenance (as opposed to improvement or “gains”) of vision 95.1% and 95.6% (respectively) of the time. Id.; see Prelim. Resp. 34–37 (citing Ex. 1001, 13:8–27; Ex. 1014, 4, 6; Ex. 1030, 9; Ex. 2021 ¶¶ 109–111; Ex. 2022). Thus, the evidence shows that, although most would, about 4–5% of patients (or, possibly, an even higher number based on Patent Owner’s cited evidence––Ex. 1030, 9) would not see the gains in visual acuity required by claims 1 and 26 or the maintenance in visual acuity required by claim 29. It is well established that “[i]nherency . . . may not be established by probabilities or possibilities” and “[t]he mere fact that a certain thing may result from a given set of circumstances is not sufficient.” In re. Oelrich, 666 F.2d 578, 581 (CCPA 1981) (quoting Hansgirg v. Kemmer, 102 F.2d 212, 214 (CCPA 1939)).

“Relating to the claim construction, the Federal Circuit found that patent at issue was “clear” that the tissue fibrosis, recited by the claim as arrested or regressed by the otherwise recited treatment, was not the same as and did not necessarily accompany the symptom of erectile disfunction (taught in and the focus of the relied-upon prior art), although the former (fibrosis) may frequently result in the latter (disfunction). Id. at 1059. The Federal Circuit held that the “arresting or regressing” clause was more than a mere statement of intended result, but was a limitation carrying patentable weight because the phrase was drafted as a part of a separate step of the method rather than of the preamble, the “arresting or regressing” language demanded efficacy, and the efficacy was linked to specific treatment minimum duration and dosage. Id. at 1060–61. The patients exhibiting these two issues were not necessarily the same. In part because the Board did not consider the arresting/regressing result limitation in its unpatentability analysis, the Federal Circuit agreed with the patent owner that the Board’s findings were insufficient. Id. at 1064, 1067. The Federal Circuit found that that prior art reference relied upon in the Board’s decision for teaching the claimed treatment, and also relied upon to link the condition of fibrosis with the symptom of erectile dysfunction, did not teach treating a population of patients suffering from erectile dysfunction only because of a fibrosis condition and, even though such patients may have had fibrosis, it was not certain; and further found that other cited prior art did not make certain a link between fibrosis and such dysfunction. Id. at 1065–66. This, the Federal Circuit found, was error. We find in agreement with Patent Owner that the results limitations of the challenged claims are limitations and must be given patentable weight for the same reasons arresting or regressing a tissue fibrosis was a limitation in Los Angeles Biomed. Similarly, here the claims are directed to expressly required results of the administration of aflibercept to patients at 2 mg at an initial dose, in at least one secondary dose 4 weeks later, and in at least one tertiary dose 8 weeks later. Therefore, we find that in claim 1, “wherein the patient achieves a gain in visual acuity within 52 weeks following the initial dose,” is a limitation. Further, in claim 26, “wherein the method is as effective in achieving a gain in visual acuity as monthly administration of 0.5 mg of ranibizumab by intravitreal injection in human subjects with age-related macular degeneration at 52 weeks following the initial dose,” is a limitation. And, in claim 29, “wherein the method is as effective in maintaining visual acuity as monthly administration of 0.5 mg of ranibizumab by intravitreal injection in human subjects with age-related macular degeneration at 52 weeks following the initial dose,” is a limitation.” slip op. at 17

“As explained in our Institution Decision (Dec. Inst. 5–6), we do not discern a substantive difference between the parties’ respective definitions for the level of ordinary skill in the art. Although Petitioner states a POSITA must have one to two years of postdoctoral research experience and Patent Owner’s definition requires at least five years of “research experience,” Patent Owner’s definition does not indicate a specific time for that research (i.e., it could include research during or after a doctoral program). Neither party addresses or contests the other party’s definition in their post-institution papers. See generally PO Resp.; Pet. Reply; PO Sur-reply. Accordingly, we find the parties’ respective definitions to be equivalent and consistent with the level of ordinary skill in the art as reflected by the prior art in this proceeding. See Okajima v.

- Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed patent owner constructionDecided for patent owner
“amount.” Pet. Reply 14. Patent Owner, however, argues that we erred in our construction because the Specification explicitly defines “effective amount” to mean “the amount of herbicide required to achieve at least about 65% phytotoxicity of conventional [i.e., wild, non-mutant] rice (e.g., red rice) in field applications.” PO Resp. 10 (quoting Ex. 1001, 6:34–37). Because the inventors served as their own lexicographers, Patent Owner asserts the Specification’s express definition controls. Id. at 10–11 (citing Martek Biosciences Corp. v. Nutrinova, Inc., 579 F.3d 1363, 1380 (Fed. Cir. 2009) (“When a patentee explicitly defines a claim term in the patent specification, the patentee’s definition controls.”)). Nevertheless, Patent Owner acknowledges that the “less than 10% injury” language “is indeed a limitation of the ’346 Patent claims.” Id. at 11. Having considered the arguments and evidence presented at trial, we agree with Patent Owner that the inventors acted as their own lexicographer to define “effective amount” and that that definition governs its meaning. Phillips, 415 F.3d 1316 (“[O]ur cases recognize that the specification may reveal a special definition given to a claim term by the patentee that differs from the meaning it would otherwise possess. In such cases, the inventor’s lexicography governs.”). We, therefore, construe the term “effective amount” to mean “the amount of an herbicide required to achieve at least about 65% phytotoxicity of conventional rice (e.g., red rice) in field applications.” As explained further below, however, whether incorporated into the construction of “effective amount” or not, the claim language itself further requires that the “effective amount” encompass a specific range of amounts of herbicide (i.e., 14 g AI/Ha to 40 g AI/Ha of quizalofop) and cause “less than 10% injury” to the mutant rice. See Ex. 1001, claim 1.” slip op. at 10

“Mankin would derive the herbicide range suggested by Patent Owner and Dr. Somers from the “rules of thumb,” that range is much broader than the claimed range. Claim 1 recites that the effective amount is 14 g AI/Ha–40 g AI/Ha of quizalofop, but, according to Dr. Somers’s calculations from the Assure II herbicide label, a POSITA would understand the effective amount to be 19.25–154 (or 19.25–184.8) g AI/Ha. Ex. 2036 ¶ 54; PO Resp. 38. Patent Owner does not identify anything in the specification that would allow a POSITA to “immediately discern” the specific range limitations of the claims. See General Hospital, 888 F.3d at 1372. As the Federal Circuit has stated, “one cannot disclose a forest in the original application, and then pick a tree out of the forest and say here is my invention.” Purdue Pharma, 230 F.3d at 1326. Thus, we are not persuaded that the disclosure of a broad range of effective amounts via the Assure II herbicide label coupled with Dr. Somers’s undisclosed “rules of thumb” provide written description support for the narrower range limitations of the claims. Moreover, we agree with Petitioner that Patent Owner is impermissibly working backward from the claimed ranges to determine whether Dr. Somers’s “rules of thumb” can be used to re-create the claimed range from the herbicide label. Pet. Reply 15. That is not the test for written description. Written description “requires a statement of an invention, not an invitation to go on a hunting expedition to patch together after the fact a synthetic definition of an invention.” Indivior UK Ltd. v. Dr. Reddy’s Labs. S.A., 18 F. 4th 1323, 1329 (Fed. Cir. 2021). Accordingly, we are not persuaded that Dr. Somers’s “rules of thumb” applied to the extrinsic herbicide label would be understood by a POSITA as a description in Mankin of the range limitation of the claims. Rather, as Dr. Somers concedes, his “rules of thumb” in conjunction with the herbicide label represent a starting point for a POSITA to test plants to determine what the effective amount range should be. See Ex. 2036 ¶ 53 (referring to a “dose response analysis” between 0.5x and 4x). But “a ‘mere wish or plan’ for obtaining the claimed invention is not sufficient.” See Centocor Ortho Biotech, Inc. v.

“We are not persuaded. Given the state of the art in 2017, and the known availability of the G2096S seeds at that time, we find the ’346 patent specification enables the claims. The ’346 patent specification clearly describes the G2096S mutant ACCase rice and its use in the claimed method for treating rice. See, e.g., Ex. 1001, 2:37–45, 57:51–61. Contrary to Petitioner’s assertion, the ’346 patent specification has not omitted the G2096S herbicide tolerant rice. Rather, the ’346 patent specification expressly identifies the G2096S mutant rice that possesses the phenotype of tolerance to the effective amounts of herbicides, and describes the method for treating that mutant rice with those effective amounts. See, e.g., id. at 8:8–12; 57:51–61. Thus, we are not persuaded that we erred in relying on Hinga’s seed deposits to determine that Petitioner has failed to meet its burden to prove that the ’346 patent specification fails to enable the challenged claims.

“labels is akin to relying on literature that clearly provides, on its face, the missing disclosure, as in Falkner. Id. On the contrary, Patent Owner’s argument makes clear that the herbicide labels, by themselves, are insufficient to describe the claimed range limitation. Specifically, because the label ranges do not align with the claimed ranges, Dr. Somers had to make additional assumptions and inferences to support Patent Owner’s written description argument. For example, to calculate the potential effective amount range of herbicides, Dr. Somers applied several different “rules of thumb,” none of which are disclosed in the Mankin specification. See Ex. 2036 ¶¶ 34, 54. According to Dr. Somers, to determine the effective amount for a plant with an unknown response to an herbicide, a POSITA “would naturally test the lowest label (1X) rate of the herbicide, along with a few rates below (starting at about half-X) and above the 1X rate (up to 4X) of the herbicide, to determine the effective dose for this ‘uncharacterized’ plant.” Id. ¶ 34. Dr. Somers refers to this as a “dose response analysis.” Id. ¶ 53. In other words, to determine what the actual effective amount of herbicides should be, Dr. Somers explains that a POSITA would have to test the plants at these “rule of thumb” amounts to determine the effective range. Id. ¶ 34. Given the additional assumptions and inferences that must be made to the herbicide labels to arrive at the range limitations, we are not persuaded that relying on the extrinsic herbicide labels for written description support is proper in this case. That said, even if we were to allow Patent Owner to rely on the herbicide labels and the “rules of thumb” for determining the effective herbicide dose, Patent Owner admits that the ranges calculated from the herbicide labels are broader than the range limitations of the claims. See PO Resp. 39. As Petitioner notes, however, the Mankin Application does not provide any guidance as to whether the effective amount range of herbicide would include a 0.5x dose, a 2x dose, or the 4x dose, such that a POSITA could immediately discern the claimed range from the herbicide label.17 Pet.

“Dr. Somers, however, relies on the label for Fusilade II, which is a different fluazifop-P-butyl herbicide with a different range of 52.98–103.96 g AI/Ha, which—not surprisingly—aligns more closely with the claimed range of at least 56–150 g AI/Ha. Ex. 2036 ¶ 52. We note that Fusilade II does not appear to be one of the listed herbicides in Table 1, whereas Fusilade DX is. Ex. 2034 ¶ 219 (listing “Fusilade, Fusilade 2000, Fusilade DX, ICI-A 00009, ICI-A 00005, SL-236, IH-773B, TF-1169, and Fusion” as examples of synonyms and trade names for fluazifop-P-butyl). Regardless, that the dose range differs for the same herbicide calls into question the credibility of Dr. Somers’s assertion that a person of ordinary skill in the art would have been able to discern the claimed range limitation by simply looking at the EPA-approved herbicide labels (and applying his “rules of thumb”).18, 19” slip op. at 33

“We begin by noting that the challenged claims do not recite that the nutritional supplements are “free of Vitamin A” or “free of all sources of Vitamin A.” Rather, independent claim 1 expressly recites that the supplement is “free of beta-carotene.” See Claim 1. Patent Owner urges us to expand the exclusion of beta-carotene to all forms of Vitamin A. That argument, however, lacks support on the current record. In particular, the support asserted by Patent Owner and its expert, Dr. Dorey, that “nutritional supplements include beta-carotene as Vitamin A equivalent,” see Prelim. Resp. 9–10 (citing Ex. 2001 ¶ 19), establishes little, on its own. Barker does not require the use of beta-carotene as its source of Vitamin A, nor does it limit the source or form of Vitamin A used. Rather, Barker discloses that several “[e]xamples of compounds having vitamin Aactivity or precursors thereof are retinol and esters thereof, such as retinyl palmitate; α- and β-carotene, β-cryptoxanthin, and lycopene.” Ex. 1011, 2:11–13. Thus, Barker discloses a number of exemplary compounds to supply Vitamin A to its nutritional supplement that are not beta-carotene. Accordingly, based on the current record, we disagree with Patent Owner’s argument that the challenged claims exclude all forms of Vitamin A and that Barker, therefore fails to anticipate those claims. Having considered the arguments and evidence at this stage in the proceeding, we are persuaded that Petitioner has shown sufficiently for institution that Barker discloses a nutritional supplement that is “free of beta-carotene.” Therefore, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing in showing that claims 1, 2, 5, and 9–12 are anticipated by Barker.” slip op. at 11

“For the reasons provided below, we determine Petitioner has satisfied the threshold requirement set forth in 35 U.S.C. § 314(a). Because Petitioner has demonstrated a reasonable likelihood that at least one claim of the ’127 patent is unpatentable, we institute an inter partes review of all challenged claims on each of the Grounds raised in the Petition. See SAS Inst., Inc. v. Iancu, 138 S. Ct. 1348, 1359–60 (2018); PGS Geophysical AS v. Iancu, 891 F.3d 1354, 1360 (Fed. Cir. 2018) (interpreting the statute to require “a simple yes-or-no institution choice respecting a petition, embracing all challenges included in the petition”); see also Guidance on the Impact of SAS on AIA Trial Proceedings (April 26, 2018).1 A.” slip op. at 2

“Patent Owner does not address the above definitions in its Preliminary Response but its expert, Mr. Goldberg, disagrees with Petitioner’s first definition insofar as it requires an academic discipline emphasizing both electrical and thermal technologies. Ex. 2051 ¶ 16. In this respect, Mr. Goldberg states that “he is unaware of such an academic discipline being available, whereas, Petitioner’s expert, Dr. Anthony, appears to assert that he has worked with “many such persons.” Cf. Ex. 2051 ¶ 16 with Ex. 1003 ¶ 21. Mr. Goldberg states that one of ordinary skill in the art would have had a Bachelor of Science degree in an academic discipline emphasizing the design of electrical systems, in combination with training or at least one to two years of related work experience with thermal management of electrical systems and capture and processing of data or information, including physiological monitoring technologies. Alternatively, the person could have had a Master of Science degree in a relevant academic discipline with less than a year of related work experience in the same discipline. Ex. 2051 ¶ 16. Despite providing an alternative definition of one of ordinary skill in the art, Mr. Goldberg indicates that his opinions with respect to the applied. Id.

- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed board ownOther
“At this stage of the proceeding, we find the language “to reliably estimate LED wavelengths” and “used to estimate wavelengths of multiple LEDs” descriptive of intended use of the underlying terms rather than descriptive of what they are. Although Patent Owner points to evidence that certain embodiments of the ’127 patent use “thermal mass” and “bulk temperature” in the manner described in Patent Owner’s proposed constructions, we decline to import these use limitations into the claim terms. See In re Prater, 415 F.2d 1393, 1404–05 (CCPA 1969) Reading a claim in light of the specification, to thereby interpret limitations explicitly recited in the claim, is a quite different thing from reading limitations of the specification into a claim, to thereby narrow the scope of the claim by implicitly adding disclosed limitations which have no express basis in the claim. We further note that Patent Owner fails to evidence the meets and bounds of “reliably estimate[ing] LED wavelengths,” such that the construction appears indefinite. In this respect, we note the Specification’s teaching that some embodiments include “a relatively significant thermal mass, which stabilizes and normalizes the bulk temperature so that the thermistor measurement of bulk temperature is meaningful.” Ex. 1001, 10:62–11:4. Considering the intrinsic evidence, we understand a “meaningful” temperature reading in the context of the ’127 patent to be one on a scale relevant to estimating LED wavelengths. aspects of construction upon which the parties appear to agree (see e.g., Prelim. Resp. 24 (citing Ex. 1012, 213)), we provisionally construe “thermal mass” as a mass having resistance to temperature change on a scale relevant to estimating LED wavelengths, and “bulk temperature” as a temperature representative of all or substantially all of a thermal mass.” slip op. at 18
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“With respect to motivation to combine, Petitioner posits that one of ordinary skill in the art would have been motivated “to implement a thermal core as suggested by Chadwick in Yamada’s board/substrate 15” to achieve various benefits, such as to “reduc[e] the amount of heat transmitted to the patient and increasing the ‘exposure time’ by which the patient can don the sensor without discomfort or heat-related safety concerns,” and/or “mitigate heat-induced spectral shifts in the wavelengths of light emitted by LEDs” Pet. 15–18; Ex. 1003 ¶¶ 42–48. With respect to the first of these, Patent Owner argues that motivation is lacking because Chadwick’s metal core heat (citing Ex. Parte Burns, Appeal No. 2016-00351, 2017 WL 2132361, *2 (PTAB Apr. 28, 2017)). This would appear contrary to Patent Owner’s assertions that “Yamada provides no discussion regarding the purpose, function, or use of substrate 15,” whereas the purpose of Chadwick’s metal core is to dissipate heat and act “as a heat sink to cool the electronics.” Prelim. Resp. 35, 37 (citations omitted). As such, we do not find Patent Owner’s argument availing. With respect to Petitioner’s argument that one of ordinary skill in the art would have been motivated to combine Chadwick and Yamada to “mitigate heat-induced spectral shifts in the wavelengths of light emitted by LEDs,” Patent Owner argues that “the claimed invention does not reduce wavelength shift; in fact, the ’127 patent accepts wavelength shift and provides a solution to compensate for it.” Prelim. Resp. 42. Accordingly, Patent Owner asserts, motivation is lacking because “[r]educing wavelength shift points in a different direction from the invention.” Id. at 43 (citing Ex. 2051 ¶ 80. This argument is also unavailing because, on the current record, claim 7 does require a solution to compensate for wavelength shift. See Section II.C.2, above. Accordingly, Petitioner’s proposed motivation does not “point[] in a different direction,” as Patent Owner contends. Patent Owner similarly argues that Petitioner has not shown a reasonable expectation of success because “[t]here is no evidence anyone before the inventors would have expected that a thermal mass could be designed to provide a bulk temperature to reliably estimate multiple LED wavelengths.” Again, Patent Owner’s argument is predicated on Patent Owner’s interpretation of claim 7, which we disagree with on the current record for the reasons provided above. See Section II.C.1–2. We do not read Moreover, as explained more fully above, LED wavelength has a known relationship to temperature and Petitioner has reasonably shown that LEDs of the Yamada/Chadwick combination would be thermally coupled to the thermal core, and thus dependent on the bulk temperature of the thermal core.” slip op. at 28
