      “Petitioner contends that a person of ordinary skill in the art “would have at least a Ph.D. in chemistry, metallurgy, or material science or material engineering” or, in the alternative, “would have a Bachelor of Science or Master of Science degree in one of these disciplines plus experience involving the use and design of dissolvable metal alloys for use in creating tools and other downhole parts for well drilling or completion activities.” Pet. 13–14. Patent Owner does not oppose Petitioner’s contentions regarding the level of ordinary skill in the art. PO Resp. 12 n.4.

      “With respect to claim 19, Petitioner proposes constructions for the terms “in situ precipitate” and “a plurality of particles of said in situ precipitate having a size of no more than 50 µm.” Pet. 11–12. With respect to claims 76–81, Petitioner proposes a construction for the term “wherein said additive material includes one or more metal materials selected from the group consisting of 0.1–35 wt. % copper, 0.1–24.5 wt. % nickel and 0.1–20 wt. % cobalt.” Id. at 13. Patent Owner contends no claims require construction for purposes of this Decision. PO Resp. 12 n.4, 17–18; Mot. 16–17.

    • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateWritten description adequateMixed

      “Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed. Cir. 2001) (noting that a description of the “present invention” as having a particular structure “is strong evidence that the claims should not be read to encompass the opposite structure”). Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan. Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed. Cir. 2011) (noting that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority . . . Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120”). Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28. In view of the foregoing, we are not persuaded that Patent Owner has demonstrated that the inventors of the priority applications were in possession of a magnesium cast composite that included less than 50 wt. % magnesium, or greater than 50 wt. % additives. As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

    • Disclosure Requirements (§112) › Definiteness (Nautilus)DefiniteIndefiniteMixed

      “The definiteness requirement of § 112(a) is satisfied when “a patent’s claims, viewed in light of the specification and prosecution history, inform those skilled in the art about the scope of the invention with reasonable clarity.” Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898, 910 (2014); see 37 C.F.R. § 42.100(b) (changing the claim construction standard used to review a claim proposed in a motion to amend from the broadest reasonable construction to the “same construction standard that would be used to construe the claim in a civil action under 35 U.S.C. [§] 282(b)”). Proposed substitute claim 104 generically requires “in situ precipitate” and also a specific type of in situ precipitate: “in situ galvanically-active intermetallic precipitate.” Mot. Appendix A. Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence. Mot. Reply 4. As such, we do not find that this part of proposed substitute claim renders claim 104 indefinite.” slip op. at 22

      “On this record, Patent Owner’s argument is unavailing. First, the evidence of record indicates that Li and Wu are analogous art. Pet. 70; Ex. 1003, Bhattacharjee Decl. ¶ 201. For example, the ’845 patent, Li, and Wu are all directed to the same field of endeavor, namely, computer networking and routing data packets. Ex. 1001, 1:17–21, Ex. 1003 ¶ 201; Ex. 1037, 1; Ex. 1039, 9. Second, the evidence of record indicates that a person of ordinary skill in the art would have had a reasonable expectation of success in combining the cited teachings of Li and Wu. Pet. 78–79 (citing Ex. 1003, Bhattacharjee Decl. ¶ 207). As discussed above, Petitioner relies on Wu’s teaching that an IPv6 destination address includes a destination port number. Pet. 79–80 (citing Ex. 1003, Bhattacharjee Decl. ¶ 211). Even if Patent Owner is correct that Li and Wu address the interoperability of IPv4 and IPv6 networks from different perspectives, a person of ordinary skill in the art would have reasonably expected that Wu’s destination port number could be incorporated into the unused padding in Li’s IPv6 destination address. Pet. 76–80; Ex. 1003 ¶¶ 199–212. On this record, Petitioner shows sufficiently that an ordinarily skilled artisan would have had reason to combine the cited teachings of Li and Wu.” slip op. at 51

      “PHOSITA) at the time of the ’532 patent “would have had at least a Bachelor’s degree in the field of chemistry, chemical engineering, polymer chemistry, or materials science and at least three years of relevant work experience in the field of high strength fibers.” Pet. 8 (citing Ex. 1003 ¶ 18). Petitioner adds that individuals with different educational backgrounds could still be of ordinary skill in the art if they have “additional experience [that] compensates for a deficit in their education and experience stated above.” Id. According to Patent Owner, a person or ordinary skill in the art, would have (i) a bachelor’s degree in chemistry, polymer chemistry, materials science, chemical engineering, or biomedical engineering and (ii) three years of experience in designing and manufacturing gel-spun UHMWPE yarns. At this level of skill, a PHOSITA would have a detailed understanding of the information provided in the Technology Background, Section II, supra, including (i) the differences between linear HDPE and UHMWPE, (ii) the history underlying Section 73.1015 and the early failures of the 1960s-era blue, melt-extruded polyethylene sutures, (iii) why the molecular orientation of polyethylene molecules leads to strong yarns in the special case of gel-spun UHMWPE, and (iv) the challenges associated with coloring gel-spun UHMWPE yarns, especially for end-use medical applications. Prelim. Resp. 33–34. We note that the parties’ proposed definitions are largely similar, except that Patent Owner additionally recognizes a Bachelor’s degree in biomedical engineering and requires experience in designing and manufacturing gel-spun UHMWPE yarns.

      “a skilled artisan would have understood that the “gel spinning” process recited in the claims requires the use of a solvent during the spinning process. Indeed, the Specification describes this term, as follows: Gel spinning is understood to include at least the steps of spinning filaments from a solution of ultra-high molecular weight polyethylene in a spin solvent; cooling the filament obtained to form a gel filament removing at least partly the spin solvent from the gel filament; removing at least partly the spin solvent from the gel filament; and drawing the filament in at least one drawing step before during or after removing spin solvent. Ex. 1001, 2:31–37. We recognize the inventor’s lexicography as dispositive with respect to the meaning of the term “gel spinning.” See Phillips v. AWHCorp., 415 F.3d 1303, 1316 (Fed.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITADecided for patent owner

      “Claim 1 describes gel spinning as the manner by which the filaments comprised in the claimed colored multi-filament yarn are obtained. This, on its face, is a product-by-process claim element because it describes the filament structure being obtained in a particular way, i.e., by gel spinning. See Kamstrup A/S v. Axioma Metering UAB, 43 F.4th 1374, 1382 (Fed. Cir. 2022) (agreeing with the Board that “cast in one piece” is a product-by-process claim element as it describes the structure being cast “in a particular way”). For this element to be limiting, it must impart “structural and functional differences” that distinguish the claimed product from the prior art. See Amgen Inc. v. F. Hoffman-La Roche Ltd, 580 F.3d 1340, 1365–67 (Fed. Cir. 2009). Patent Owner argues persuasively that gel spinning imparts structural and functional differences to the claimed product because the process “creates overlap between polyethylene molecules within the UHMWPE filaments that maximizes the intermolecular Van der Waals interactions, resulting in highly crystalline filaments with high tensile strength.” Prelim. Resp. 38, 22 (citing Ex. 1014, 62–66). According to Patent Owner, “the structure of the gel spun UHMWPE is substantially different from other types of UHMWPE such as compression-molded and ram-extruded UHMWPE used to make joint replacements and other orthopedic implants.” Id. at 38.” slip op. at 9

      “On this record, Patent Owner’s argument is unavailing. First, the evidence of record indicates that Li and Wu are analogous art. Pet. 70; Ex. 1003 ¶¶ 213–214. For example, the ’844 patent, Li, and Wu are all directed to the same field of endeavor, namely, computer networking and routing data packets. Ex. 1001, 1:17–21; Ex. 1003 ¶ 213; Ex. 1037, 1; Ex. 1039, 9. Second, the evidence of record indicates that a person of ordinary skill in the art would have had a reasonable expectation of success in combining the cited teachings of Li and Wu. Pet. 69; Ex. 1003 ¶ 210. As discussed above, Petitioner relies on Wu’s teaching that an IPv6 destination address includes a destination port number. Pet. 68–69; Ex. 1003 ¶ 207. Even if Patent Owner is correct that Li and Wu address the interoperability of IPv4 and IPv6 networks from different perspectives, a person of ordinary skill in the art would have reasonably expected that Wu’s destination port number could be incorporated into the unused padding in Li’s IPv6 destination address.

      “A person of ordinary skill in the art at the time of the alleged invention of the ’770 patent . . . 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 communication . . . More education can supplement practical experience and vice versa. Pet. 4 (referencing Ex. 1002 ¶¶ 17–18). Patent Owner does not dispute the level of ordinary skill in the art. PO Resp. 5. For the purposes of this Decision, we apply Petitioner’s undisputed definition of the level of ordinary skill in the art. We find that this definition is consistent with the prior art of record and the skill reflected in the Specification of the ’770 patent.” slip op. at 13

      “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. 45–46. As will be evident from our analysis below, we conclude that it would have been obvious to employ an IP-based communication. There is no dispute that an IP-based communications channel satisfies the term channel as used in the claims. Therefore, we determine that the term “channel” does not require an express construction to resolve the parties’ disputes regarding the asserted grounds of unpatentability. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

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., 764 F.3d at 1398. As discussed in greater detail below, we do not find the asserted claims, read in light of the Specification,6 to require that the pre-call information having a bridge number be transmitted after a call to a secondary number is made. We begin with the words of the claim. See, e.g., Phillips, 415 F.3d at 1314 (“[T]he context in which a term is used in the . . . claim [at issue] can be highly instructive.”). The complete “transmitting” step recites: transmitting pre-call information to the handset over the at least one data channel the pre-call information including the bridge telephone number and the handset-associated telephone number, such that the handset is capable of displaying the handset-associated telephone number to a user and, based on user input, accepting the incoming call by connecting with the switch over the at least one voice channel using the bridge telephone number. Ex. 1001, 10:29–37. The plain language of the claims requires that the pre-call information is transmitted such that the handset is capable of displaying the handset-associated telephone number and accepting the incoming call. Nothing in this language precludes the pre-call information from being transmitted before the incoming call is received at the switch— the requirement is that the information makes the handset capable of displaying the handset-associated telephone number to a user and accepting” slip op. at 18

      “The Petition, at page 41, makes the argument. We also do not agree with Patent Owner and Dr. Akl that a person having ordinary skill in the art would not have been motivated to employ IP-based communications for the pre-call information. 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

      “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.

      “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.
