And, as set forth above, Patent Owner asserts that, for the sake of its present arguments, it matters not which of the two proposed definitions we use for this proceeding. Prelim. Resp. 21. Thus, at this stage, we accept and use Petitioner’s proposed definition of the ordinarily skilled artisan, which, unlike Patent Owner’s, does not implicate reliance on the knowledge of people other than the individual ordinarily skilled artisan.

“We do not credit Dr. Anthony’s testimony, which is based on the arbitrary shading in Figure 7 (see Ex. 1002 ¶ 174), that Schröder teaches or suggests limitation 1[d] because it (1) is inconsistent with Petitioner’s reasoning for limitation 1[c], and (2) it is based on an admitted misreading of the embodiment of Schröder’s Figure 5 (see Ex. 1002 ¶ 175). As to the first item, Dr. Anthony states that “a POSITA would have been motivated to place a battery in a part of the cavity that is far from a PCB holding other electrical components because that configuration allows for better thermal management.” Ex. 1002, para. 175. The problem with this statement is that Petitioner relies on Schröder’s teaching that inlay 12, i.e., the alleged PCB, could include “other electrical components,” such as a battery to support its position that Schröder suggests placing a battery between the ring halves. See, e.g., Pet. Reply 2 (pointing to Dr. Mercier’s depo testimony that inlay 12 with “other components” is inserted between ring halves); id. at 3 (relying on Schröder’s teaching about placing components in depressions on inlay 12).

Patent Owner agrees with Petitioner, however, that no terms need to be construed to decide the issues raised in the Petition. Id. at 27. We reviewed the constructions adopted by the ITC. Ex. 2016, 5, 6, 14. 8 In the ITC proceeding, the ALJ adopted the parties’ agreed-upon constructions that: (1) the preamble of claim 1 [a finger-worn wearable ring device] is limiting; (2) [positioned/configured to fit] within a “cavity” is [positioned/configured to fit] within a “hollow space”; and (3) [the internal housing component] “coupled with” [the external housing component] is [the internal housing component] “connected with” [the external housing component]. Ex. 2016, 5. 9 In the ITC proceeding, the ALJ construed the claims such that: (1) the internal and external housing components of claims 1, 12, and 17 enclose space and do not necessarily exclude potting material; and (2) “circumferential,” as recited in claims 1, 17, and 18, does not require a closed shape. Ex. 2016, 14, 17. These constructions are not germane to the issues we need to decide to resolve this proceeding. Thus, we agree that no explicit claim construction is necessary for this decision.

“The record supports Patent Owner’s argument that Mestas’s batteries are much too large to fit within a ring form factor, and “Mestas’s batteries, layout, and other components . . . would have to be scaled down 5 to 10 times to be appropriately sized for a finger worn ring.” Resp. 64 (internal quotation marks omitted) (citing Dr. Anthony’s cross-examination testimony at Ex. 2021, 313:12). Moreover, we do not credit Dr. Anthony’s testimony that miniaturization of the battery would have been “trivial to implement.” Ex. 1002 ¶ 242. Dr. Anthony admitted on cross-examination that it would not have been within the level of skill of a person having ordinary skill in the art to design a smaller version of Mestas’s battery, and that such a person would need to procure a battery of the appropriate size and specifications for implementation in a finger-ring from a battery manufacturer. Ex. 2021, 315:9–318:9. Yet Dr. Anthony had not ascertained, for purposes of his testimony, whether there was a battery available in 2013 that was appropriate to fit within the inlay space of the modified version of Schröder’s finger-ring that he and Petitioner allege would have been obvious to one of skill in the art at that time. Id. at 321:5–10. Further, we credit Dr. Mercier’s testimony that Dr. Anthony’s testimony fails to consider the differences in power requirements between Mestas and Schröder or to account for the constraints of such a substantially smaller form factor in Schröder’s finger-ring as compared to Mestas’s wrist device. Ex. 2018 ¶¶ 159–160. Although large curved batteries suitable for use in a wrist band or other larger wearable device, such as shown in Mestas, were known at the time of the ’178 patent, we also have evidence that prior art “finger ring wearables up to the ’178 patent had used ‘coin’ type batteries.” Id. at 66 (citing Ex. 2018 ¶ 161). We credit Dr. Mercier’s testimony that a person having ordinary skill in the art would look to a coin type battery for the necessary power requirements of Schröder’s device. Ex. 2018 ¶ 161. Indeed, this testimony is consistent with the other art of record that consistently shows the use of flat batteries in finger-ring devices, often stacked above and protruding from the general ring shape of the device. See, e.g., Ex. 1005 (Niwa), Figs. 22, 28; Ex. 2025 (Asada ’701 patent), Fig. 4; Ex. 1035 (Rhee), Figs. 7-1, 8-1, 8-2; Ex. 1037 (Asada article), Fig. 9; Ex. 1034 (Asada ’199 patent), Fig. 2; Ex. 1028 (Kimura), Fig. 24; Ex. 2018 ¶¶ 61–70. In fact, Oura’s first-generation ring design, released in 2015, used a Superbowl ring-type design, with the battery and other components mounted on top of the ring. Ex. 2034; Ex. 2018 ¶ 71. Based on these findings, Petitioner has not met its burden to show by a preponderance of the evidence that a person having ordinary skill in the art would have been led to modify Schröder’s finger-ring to place a curved battery between the internal and external housing components in light of the teachings in Mestas. Thus, Petitioner has not met its burden to show by a preponderance of the evidence that dependent claim 3 of the ’178 patent is unpatentable over Schröder and Mestas.” slip op. at 38

“Petitioner argues that one of ordinary skill in the art would have found the proposed modification obvious for several reasons. Pet. 30. For instance, Petitioner argues that “Unger contains an express teaching, suggestion and/or motivation to incorporate an element such as Smith’s torsional spring into the lower and/or upper mount assemblies 308, 312 to facilitate attachment and detachment.” Id. Namely, Petitioner points to Unger’s disclosure that device mounts 308, 312 may be flexible or resilient so that device mounts 308, 312 may be bent to engage a portion of hearing protection device 108 and are then allowed to return to a normal state to secure communication device 104 to hearing protection device 108. Id. at 30–31 (quoting Ex. 1004, 6:20–37). Petitioner adds that one of ordinary skill in the art would have understood this disclosure “to teach that mount arms 308, 312 could be removable from housing 304 (e.g., as mount arm 312 is in Figure 6) and/or they could be designed to be ‘flexible’ or ‘resilient’ such that they can be manipulated,” and “that ‘resilient’ is defined as ‘bouncing or springing back into shape, position, etc. after being stretched, bent, or, esp., compressed.’” Id. at 31 (citing Ex. 1002 ¶ 117). Thus, according to Petitioner, this disclosure of Unger suggests using a torsion spring. Id. In addition, Petitioner asserts that one of ordinary skill in the art would have understood Unger’s disclosure to “suggest the use of a torsion designed to impart this functionality.” Pet. 30 (citing Ex. 1002 ¶ 118). Petitioner also asserts that one of ordinary skill in the art would have “understood that there were a limited number of ways to impart the referenced resilient or flexible ‘manipulation,’” and “would have been motivated to look to various known solutions to impart the suggested functionality, including the torsional spring mechanism of Smith that is used in a similar hearing protection device application for a similar purpose as Unger’s mounting arms (to apply a clamping force).” Id. at 32 (citing Ex. 1002 ¶¶ 120–121). Other reasons for combining the references set forth by Petitioner are the proposed modification: (1) “would have involved applying a known technique to a known device ready for improvement to yield predictable results” (Pet. 39–49 (citing Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380 (Fed.

“the feature of the solid wire being “secured at a proximal-most end thereof within the proximal hub” was added during prosecution to overcome a rejection. Ex. 1002, 573-580. The prior art was distinguished because its guidewire “is configured to be steered and manipulated through the blood vessel, and subsequently removed, and, therefore, cannot be secured at a proximal end thereof to the luer hub 310.” Id., 578-79 (emphasis added).

“2. Patent Owner’s Arguments Concerning Claim 1 and Our Analysis a. Reasonable Expectation of Success in modifying catheters to less than 6 Fr Patent Owner asserts “Petitioner has failed to perform a proper obviousness analysis by not adequately demonstrating a reasonable expectation of success in modifying Fogarty.” PO Resp. 35. Patent Owner asserts “the category of ‘Fogarty catheters’ is broad and diverse” and “Dr. Resnick admits he has no idea whether Chengod’s or Deaton’s catheters have interior constructions similar to that of the cited Fogarty reference.” Id. at 35‒36 (citing Ex. 2002, 52:16‒57:1). Patent Owner asserts that Petitioner has therefore not demonstrated that a PHOSITA would have a reasonable expectation of success in modifying the particular catheter taught by the cited Fogarty patent (Ex. 1004) to the claimed size when considering the shaft has a spring coil and braid in addition to the outer tube and lumen. Id. Petitioner responds “(1) Fogarty did not indicate the catheter’s size; (2) Fogarty catheters smaller than 6 Fr were known and disclosed in Chengod (and Deaton); and (3) sizing Fogarty’s catheter less than 6 Fr would work (i.e., reasonable expectation of success) because it did work.” Pet. Reply 19. Petitioner asserts that Yassinzadeh “shows a catheter that is less than 6 Fr and that includes a similar spring coil construction as found in the Fogarty patent” where the “dilator 150 has a diameter of either 5 Fr or 6 Fr.” Id. at 19‒20 (citing Ex. 1033 ¶¶ 86‒97 (“Yassinzadeh”)). Petitioner asserts that Yassinzadeh’s “analogous construction being less than 6 Fr confirms a PHOSITA would have a reasonable expectation of success in sizing the catheter in Fogarty (Ex-1004) less than 6 Fr.” Id. at 20 (citing Ex. 1034 ¶ 97).

“We have authority to determine whether to institute a post-grant review under 35 U.S.C. § 324. Institution of a post-grant review is authorized by statute when “the information presented in the petition . . . would demonstrate that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” 35 U.S.C. § 324(a). A post-grant review may also be instituted when “the petition raises a novel or unsettled legal question that is important to other patents or patent applications.” See id. § 324(b). Applying that standard on behalf of the Director (37 C.F.R. § 42.4(a)) and in consideration of the Petition, Preliminary Response, and the evidence of record, we determine that the information presented shows that it is more likely than not that Petitioner would prevail in establishing unpatentability of claims 1–3 of the ’201 patent.” slip op. at 2

“At this stage of the proceedings, neither Petitioner’s nor Patent Owner’s proffered definitions of the level of skill appear appropriate. Petitioner’s proposal requires as little as a bachelor’s degree in organic chemistry and two years of experience as a laboratory technician working on development of molecules with targeted biological activity, and an ambiguous “understanding” of certain processes. Patent Owner’s proposal, other the other hand, requires multiple years of both formal training and actual, practical experience in highly specialized fields that involve detection of optical or radiolabeled compounds and use of molecular imaging techniques such as PET and SPECT. For the purposes of this decision, on the record at this time, we find that a POSA would have had a Ph.D. in chemistry, biochemistry, or a comparable field or an M.D., and at least four years of experience in chemical synthesis of compounds that may be used to target biologically-significant tissues. This definition appears consistent with the level of skill shown in the prior art references of record. See Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007). The parties will have the opportunity to cross-examine Dr. Martin and Dr. VanBrocklin in this proceeding to develop a full record for us to determine the weight that each expert’s testimony should be given. We invite the parties to further brief the definition of a POSA here, and whether we should discount either experts’ testimony due to lack of qualifications.” slip op. at 8

“c) Analysis On the present record, we find that “low molecular weight” is not limited to Patent Owner’s proposed “from about 50 Daltons to about 1,500 Daltons.” The cited evidence relied on in the Pomper Declaration all concerns metabolomics and metabolites, and we find no reason that even a vague definition of metabolites applies to the claimed compounds. See Ex. 1002, ¶ 102. Moreover, the uncontested fact that several of the B moieties alone—without the A moiety or L linker—specifically identified in the ’201 patent fall outside of Patent Owner’s proposed definition is persuasive (see id., ¶ 103), as we normally do not interpret claim terms in a way that excludes examples disclosed in the specification. See, e.g., Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d 1295, 1305 (Fed. Cir. 2007) (rejecting proposed claim interpretation that would exclude disclosed examples in the specification). In addition, the opinion stated in the Pomper Declaration that “the term of ‘low molecular weight’ is well accepted in the chemical arts’” and the declarant “recognize[s] that low molecular weight compounds would have a molecular weight of typically form about 50 Daltons to about 1,500 Daltons” is offered by a co-inventor. We, as factfinder, have discretion to weigh the credibility of expert witnesses and to give each item of evidence such weight as appropriate. See In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1368 (Fed. Cir. 2004) (“[T]he Board is entitled to weigh the declarations and conclude that the lack of factual corroboration warrants discounting the opinions expressed in the declarations.”). In this case, we find that the published references on metabolites do not support the opinion. In re Am. Acad. of Sci. Tech Ctr., 367 F.3d at 1368 (Fed. Cir. 2004) (“[T]he Board is entitled to weigh the declarations and conclude that the lack of factual corroboration warrants discounting the opinions expressed in the declarations.”) The Pomper reference (Ex. 1006) also uses the term “low molecular weight”—without further characterization of the term—and is uninformative as to the meaning of the term. See Ex. 2002, ¶ 60; Ex. 1006, ¶ 12. The table giving the molecular weight of a “selection of compounds disclosed by Pomper” (see Ex. 2002, ¶ 62) is not persuasive in defining “low molecular weight,” as it does not explain how those included were “selected” and does not include molecular weights for all of the examples.7 In addition, Patent Owner’s definition does not appear to apply to all claimed compounds.8 7 At least one of the examples (SRV73) not included in the table appears to have a molecular weight well over “about 1,500 Daltons.” 8 See, e.g., claim 113 of Ex. 1006.

“The ’201 patent defines “alkyl” as “a straight (i.e., unbranched) or branched chain, acyclic or cyclic hydrocarbon group, or combination thereof” “ that has “the number of carbon atoms designated (i.e., C1–C10 means one to ten carbons, including 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 carbons)” and “[i]n particular embodiments, the term ‘alkyl’ refers to C1-20 inclusive, including 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 carbons” “unless otherwise stated.” Ex. 1001, 39:44–58. Although substituents at the R1x position in the claims are limited to “C1-6alkyl,” those at position R3x are not. Ex. 1001, Certif. Corr. Patent Owner’s representation that “Jansen I provides ‘the following definitions’ stating that ‘alkyls groups of this invention comprise from 1 to 6 carbon atoms’” is inaccurate. See Prelim. Resp. 19. In fact, Jansen I states: The term “alkyl” by itself or as part of another substituent refers to a fully saturated hydrocarbon of Formula CxH2x+1 wherein x is a number greater than or equal to 1. Generally, alkyl groups of this invention comprise from 1 to 6 carbon atoms. Alkyl groups may be linear or branched and may be substituted as indicated herein. When a subscript is used herein following a carbon atom, the subscript refers to the number of carbon atoms that the named group may contain. Ex. 1007, 22:16–23 (emphasis added). Neither the ’201 patent nor its incorporation by reference of Jansen I would have conveyed to a POSA that the “(CO)alkyl” of the substituent in the R3x position in the claims is intended to comprise from one to six carbon atoms or is limited to any particular length and size. “(C(O)alkyl,” having no number of carbon atoms designated, means” slip op. at 15
