      “Petitioner contends that a person of ordinary skill in the art “would have had a Master’s degree in material science, chemical engineering, chemistry, or similar field with four years of experience designing testing, and building secondary lithium batteries.” Pet. 11 (citing Ex. 1002 ¶ 51). Petitioner further contends that a person of ordinary skill in the art would have been aware of “(1) positive electrode materials, (2) negative electrode materials, (3) separators, (4) electrolytes, (5) charge-discharge parameters, and (6) protection circuits, as well as ‘battery failure modes’ such as plating and the formation of dendrites.” Id.

      “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage. In view of the foregoing, we construe “charge cut-off voltage” in claims 1 and 5 as “the maximum value to which the battery is configured to be charged.” PO Resp. 18; Ex. 2008, 217:6–11; Pet. Reply 5. Contrary to Patent Owner’s arguments, however, we do not understand the phrase “configured to be charged” to necessarily represent a single voltage for the battery that is determined based on the structure and chemistry of the battery. Pet. Reply 4–5. Rather, the charge cut-off voltage is a selected potential, or voltage, of the battery or cell at the end of charging that is controlled by a circuit or device, such as a charger or control circuit within the battery. Ex. 1001, 9:50–55; Ex. 1048, 2, 7–8; Ex. 1008, 3:9–13. And, for the reasons discussed herein, the charge cut-off voltage may be, but is not necessarily, the same as the applied voltage during charging. PO Resp. 20.” slip op. at 15

Ex. 1001, 16:56–61, 17:6–11. Although the parties dispute the precise scope of these claim terms, the parties agree that the first use of “charge cut-off voltage” in claims 1 and 5 refers to the potential of the battery as a whole (between the cathode and the anode), and not a half-cell voltage using lithium metal as a counter electrode.10 Tr. 17:1–3 (agreeing 10 With respect to the phrase “as calculated by a theoretic capacity with a charge cut-off voltage set at 4.2 V,” the parties in fact appear to be in that the first use of “charge cut-off voltage” in claim 5 refers to a full-cell voltage); Sur-reply 5; PO Resp. 22.

      “constructions. First, we agree with Petitioner that the ’641 patent indicates that the charge cut-off voltage selected for a particular battery need not be a fixed property of the battery or something that is set by the design and chemistry of the battery. Consistent with this conclusion, the ’641 patent discloses that a “charging device controls the charge cut-off voltage of the single lithium-ion cell within a range from 4.3 V to 5.8 V.” Ex. 1001, 9:50– 55. This strongly suggests that the charge cut-off voltage is controlled by the charger and is not necessarily an inherent property of the battery. Patent Owner contends that this is merely an unclaimed embodiment, but the relevant disclosure states that the charging device for the “present invention” may be any type of device “with the proviso that said charging device controls the charge cut-off voltage.” Id. at 9:50–53.” slip op. at 12

This argument is not persuasive because Mr. Juzkow unambiguously testified that charging in Uemura stopped when the applied voltage reached 4.3 V, and Uemura discloses that the battery was charged “at” a voltage ranging from 4.3 V to 2.0 V, not “to” such a voltage.

      “II. TIMELINESS OF THE PETITION UNDER 35 U.S.C. § 315(B) Pursuant to 35 U.S.C. § 315(b), “[a]n inter partes review may not be instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent.” Patent Owner argues that the Petition is untimely under 35 U.S.C. § 315(b) because Petitioner is in privity with time-barred entities. Prelim. Resp. 10– 30. However, 35 U.S.C. § 315(b) also provides that the one-year time bar “shall not apply to a request for joinder under subsection (c).” See also 37 C.F.R. § 42.122(b). Because the Petition is accompanied by a timely request for joinder (Paper 2) to the instituted proceeding (IPR2024-00017), which we grant as further discussed below, Patent Owner’s argument that the Petition is time-barred under 35 U.S.C. § 315(b) is moot, irrespective of whether Petitioner is in privity with time-barred entities.” slip op. at 5

      “B. Whether to Join Petitioner as a Party to the Cirrus IPR Joinder may be authorized when warranted, but the decision to grant joinder is discretionary. See 35 U.S.C. § 315(c); 37 C.F.R. § 42.122. A motion for joinder should (1) set forth reasons why joinder is appropriate; (2) identify any new grounds of unpatentability asserted in the petition; (3) explain what impact (if any) joinder would have on the trial schedule for the existing review; and (4) address specifically how briefing and discovery may be simplified. See, e.g., Kyocera Corp. v. Softview LLC, IPR2013- 00004, Paper 15 (PTAB April 24, 2013). As the moving party, Petitioner bears the burden of proving that it is entitled to the requested relief. 37 C.F.R. § 42.20(c). As an initial matter, we find the Motion for Joinder meets the timing requirements of 37 C.F.R. § 42.122(b) because Petitioner filed it on April 4, 2024, no later than one month after the Cirrus IPR was instituted on May 1, 2024.” slip op. at 9

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “5. “Aid the Movement of Minority Carriers” Patent Owner argues that the Petition fails to show that the applied prior art references disclose the claim limitations “requiring ‘aid the movement of minority carriers,’” as twice recited in claim 1. Prelim. Resp. 8. Patent Owner summarizes this dispute as follows: The challenged patent discloses and claims a semiconductor device with (among other things) a “drift layer having a graded concentration of dopants . . . [and] further having a first static unidirectional electric drift field to aid the movement of minority carriers.”[] The Petition should not be instituted, because (among other deficiencies) it fails to show that the prior art discloses the “aid the movement of minority carriers” claim limitation. Rather than pointing to anything in the prior art that would teach this claim limitation, the Petition assumes that any “graded concentration of dopants” would necessarily “aid the movement of minority carriers.” The Petition contains no analysis explaining why the “graded concentration of dopants” in the prior art meet the “aid the movement of minority carriers” limitation, apart from the fact that they are “graded concentration of dopants.” In other words, Petitioner reads the “aid the movement of minority carriers” limitation out of the claims completely. Id. at 1–2. Patent Owner includes additional details in support of its view that the asserted prior art fails to establish obviousness of the “aid carrier movement” limitations of claim 1. Prelim.

      “Patent Owner’s expert, Dr. Goodrich, proposes what Patent Owner characterizes as “a somewhat different level,” namely “an individual with at least a bachelor’s degree in Computer Science or related area and two years of experience developing software tools and/or computer systems for use in the area of audio or video creation, encoding, and/or distribution.” PO Resp. 13; Ex. 2007 ¶ 50. Although we agree that the respective articulations are “somewhat different,” they are generally similar, and our Decision does not depend on nuanced distinctions regarding the level of ordinary skill. Indeed, Dr. Goodrich describes his proposed articulation as “approximate,” such that “more work experience could compensate for less education or more education could compensate for less work experience.” Ex. 2007 ¶ 50. Because we find Petitioner’s proposal reasonable, consistent with the level of skill reflected by the prior art, and supported by Dr. Freedman’s testimony, we adopt it for this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art may reflect an appropriate level of skill in the art). We nevertheless note that we would reach the same ultimate conclusion that claims 1, 3, 5, 9, 12, 13, and 15 (but not claims 20 and 21) have been shown to be unpatentable by a preponderance of the evidence were we to adopt Patent Owner’s proposal.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for patent owner

      “We agree with Patent Owner’s contention that the emphasized sentence defines the term “content-related.” See PO Resp. 15–16 (Patent Owner arguing that “[t]here are thus three strong indications of lexicography: (1) ‘content-related’ is set off by quotation marks; (2) the patentee used the word ‘is’ to describe the term ‘content-related’; and (3) the patentee states what ‘content-related’ is ‘understood to mean.’” Nor does Petitioner disagree that the sentence is definitional. See Tr. 8:15–16 (referring to the “term content-related as it’s defined in the specification”). Indeed, in the Starz litigation, the district court also treated the sentence as definitional, a fact that we find significant as a matter of comity. See Ex. 1018, 111:24–112:1 (district court judge stating at Markman hearing, “I’m going to adopt . . . the express definition provided in the specification”). But like the district court, we discern insufficient reason to adopt the additional gloss that Patent Owner seeks to apply to the definition of “content-related.” That is, Patent Owner proposes that we additionally construe the phrase “syntactical meaning” within the definitional statement to arrive at Patent Owner’s proposed construction. PO Resp. 16–20. According to Patent Owner, “[t]he specification makes clear, through its use of consistent and repeated examples, that ‘syntactical meaning’ requires a specific relationship between the data segments within a data file: succeeding data segments within a data file must be ordered so as to present the content in its intended sequence when rendered.” Id. at 17 (citing VirnetX Inc. v. Cisco Sys., Inc., 767 F.3d 1308, 1317–19 (Fed. Cir. 2014); Alloc, Inc. v. ITC, 342 F.3d 1361, 1368–71 (Fed. Cir. 2003)). Patent Owner adds that the claims, the context provided by the problems solved by the ’794 patent, and the cross-examination testimony of Petitioner’s expert, Dr. Freedman, all support this additional aspect of Patent Owner’s proposed construction. Id. at 18–20. Relying on additional direct testimony by Dr. Freedman, Petitioner counters this position as “improperly import[ing] limitations from the specification that are not required by the claims” and “render[ing] other portions of claim 1 superfluous.” Reply 3 (citing Ex. 1016 ¶ 22); see Tr. 10:18–20 (Petitioner explaining at oral hearing that “the syntax information is simply just identification information which is used to find out what the order of the files is. But the identification information does not by itself indicate the order. It’s just an identifier.”). We agree with Petitioner that it would be imprudent to adopt Patent Owner’s additional gloss because, “[w]hile claims must be construed in light of the specification, . . . limitations from the specification are not to be read into the claims, . . . for ‘[i]t is the claims that measure the invention.’” Golight, Inc. v. Wal-Mart Stores, Inc., 355 F.3d 1327 (Fed. Cir. 2004) (quoting SRI Int’l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1121 (Fed. Cir. 1985) (other citations omitted). It is apparent that the Applicant for the ’794 patent understood how to define terminology recited in the claims, but chose to limit its definition of “content-related” in terms of the broader phrase “syntactical meaning” rather than through narrower specific reference to presentation order. In addition, claims 1 and 9 already specify “sequentially outputting the first and second data segments according to their chronological sequence,” which supports Petitioner’s observation that requiring an additional sequential order to “content-related . . . data segments” renders other portions of claim 1 superfluous.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Prosecution history disclaimer / disavowalDisclaimer not foundDecided for petitioner

      “As a basic principle of claim interpretation, prosecution disclaimer promotes the public notice function of the intrinsic evidence and protects the public’s reliance on definitive statements made during prosecution.” Omega Engineering, Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed Cir. 2003) (citing Digital Biometrics, Inc. v. Identix, Inc., 149 F.3d 1335, 1347 (Fed. Cir. 1998)) (emphasis added). As such, a statement during prosecution qualifies as a disavowal of claim scope only if it is “so clear as to show reasonable clarity and deliberateness” and “so unmistakable as to be unambiguous evidence of disclaimer.” Id. at 1325 (citations omitted). “Consequently, for prosecution disclaimer to attach, [Federal Circuit] precedent requires that the alleged disavowing actions or statements made during prosecution be both clear and unmistakable.” Id. at 1325–26. “The party seeking to invoke prosecution history disclaimer bears the burden of proving the existence of a clear and unmistakable disclaimer that would have been evident to one skilled in the art.” Mass. Inst. of Tech. v. Shire Pharms., Inc., 839 F.3d 1111, 1119 (Fed. Cir. 2016). And “[s]tatements by the patent owner are not considered in a vacuum; rather, the skilled artisan would look at the record as a whole in assessing claim scope.” Galderma Lab’s v.

See Ex. 1018, 109:15–22 (district court stating at Markman hearing, “I’ve also carefully reviewed the portions of the prosecution history relied on by VideoLabs, including the patentee’s arguments regarding the Shin and Rosenau references, and I’m up [sic: not6] persuaded there was a clear and unmistakable disclaimer of all assignment rules that perform assignments by using exact timing information”). slip op. at 20

      “We agree with Petitioner. The statute governing the formerly available CBM proceeding explicitly limits challenges based on “prior art that is described by section 102(a).” AIA § 18(a)(1)(C). In contrast, § 311(b) permits challenges “on the basis of prior art consisting of patents or printed publications.” The language in § 311(b) implies that, unlike CBMs, IPRs are not limited to prior art challenges solely under § 102(a). Patent Owner relies, inter alia, on Infobridge, but that case deals with public accessibility under § 102(b). Infobridge, 929 F. 3d at 1368–69. The parties do not cite to any Federal Circuit decisions that squarely address this issue. However, the Federal Circuit applied § 102(e) patent application publication prior art in an appeal from an IPR. See, e.g., Purdue Pharma L.P. v. Iancu, 767 Fed. App’x 918, 920–21, 926 (Fed.

      “provide a specific numerical analysis of the number of LEDs necessary to match a value of the DC output voltage in Nerone. PO Resp. 31–32. Based on Dr. Baker’s testimony, Petitioner provides several factors that a person of ordinary skill in the art would have considered when designing Nerone’s circuitry to satisfy the “matching” requirement of limitation 7(f). Pet. 18 (citing Ex. 1002 ¶ 120). Dr. Baker supports his testimony concerning the knowledge of these factors by one of ordinary skill with reference to disclosures in Cross and Martin. Ex. 1002 ¶¶ 121–123. Neither Patent Owner nor Dr. Ducharme dispute that a person of ordinary skill in the art would have known to consider these factors when designing Nerone’s circuit. See PO Resp. 30–43; Ex. 2001 ¶¶ 89–106. Petitioner then explains how a person of ordinary skill in the art would have used these factors to apply the teachings of Martin to configure Nerone’s circuitry so that “the forward voltage of the series-connected LEDs [] approximately match[es] the rectified AC voltage output of the above-described LED driver circuit.” Pet. 21; id. at 20–21; see also Ex. 1107 ¶ 29 (“a person of ordinary skill in the art would have understood and would have been capable of determining the appropriate number of LEDs based on the application and design of Nerone’s system such that the forward voltage drop of the LEDs . . . matches the rectified AC voltage output . . . to mitigate against overdriving or underdriving the LEDs.” (citing Ex. 1074 ¶¶ 30–31, Fig. 2)). For these reasons, we find that it was not necessary for Petitioner to provide a specific numerical calculation of the number of LEDs in its proposed modification of Nerone. We also agree with Petitioner that “matching the input voltage to the forward voltage of the LEDs had become a matter of routine optimization.” Pet. 19. Patent Owner contends that this statement is “vague and conclusory.” Sur-reply 12–13. Petitioner, however, supports this statement with the testimony of Dr. Baker. Ex. 1002 ¶¶ 120–123. Dr. Baker’s testimony, which we credit, is corroborated by both Cross and Martin. See id. (citing Ex. 1015 ¶¶ 2, 21, 22 Fig. 5; Ex. 1074 ¶ 30). In particular, Cross specifically discloses that “[t]he number of LEDs employed will vary with the intended lighting application and the value of the rectified DC voltage, wherein optimization of such is well within the skill of those in the art.” Ex. 1074 ¶ 30. Patent Owner does not dispute Cross’s statement that optimizing the number of LEDs is within the skill of an ordinarily skilled artisan. See PO Resp. 40. Martin chooses the number of LEDs “such that the maximum voltage across each individual LED . . . is low enough so as to not damage the LEDs.” Ex. 1015 ¶ 22. It also specifically discloses that “[t]he voltage across each of the individual LEDs in the array is the line voltage divided by the number of LEDs in series.” Id. (emphasis added). Consequently, Martin uses “voltage matching” to determine the number of LEDs so as not to damage the individual LEDs. See also Ex. 1002 ¶¶ 120–124 (Dr. Baker explaining that a skilled artisan “configuring Nerone’s circuit 400 would have recognized that the forward voltage of the series-connected LEDs should approximately match the rectified AC voltage output of the above-described LED driver circuit.” Id. ¶ 124.). Martin’s disclosure, thus, aligns with the reason for “matching” described in the ’400 patent. Ex. 1001, 2:24–35.” slip op. at 36

      “we consider whether that construction was intended to encompass varying durations during the creating step or the displaying step. In its opinion, the Microsoft court observed that the defendants in that case argued that “before created,” and that “the ‘duration information’ is a parameter that the user can then interact with in order to vary the display of each resource.” Ex. 1014, 22. Patent Owner, the court continued, argued that “all that is required is for the user to maintain control over the actual presentation of the resource during the ‘displaying’ step, and that no duration information need be provided during the ‘creating a show structure of nodes’ step.” Id. at 22–23. The Microsoft court “agree[d] with [Patent Owner] that the user should be able to vary the duration of the content during show structure playback. This is the ‘interactive’ component of the claim.” Id. at 23; see also Prelim. Resp. 29 (arguing that this reasoning supports Patent Owner’s position that “the claim language expressly requires that the end user be able to ‘vary said duration’ for how long resource content currently ‘is being displayed’ to the user in ‘accordance with said show structure’ to which the resource belongs”). Here, the Microsoft court expressly states that the duration is varied during show structure playback, which is a clear reference to claim 1’s step of “displaying a content corresponding to each of said resources automatically in accordance with said show structure.” The Microsoft court “also finds that some duration information must be provided when the show structure of nodes is created,” that “‘parameter’ is a helpful concept for construction,” and that “the ‘duration information’ may be understood to be synonymous with a ‘parameter,’ as that timing information is the variable that will specify how long a particular content will be displayed.” Ex. 1014, 23.

      “As noted above, the Microsoft court construed “interactively variable duration information” to mean “a parameter specifying how long a content is to be displayed by default before a subsequent content is displayed, where the viewer of the content can change the parameter.” Ex. 1014, 22. The construction itself suggests that the duration information is varied during display, because it is in the context of resources being displayed sequentially and “the viewer of the content can change the parameter.” As to Escobar, Petitioner contends that “[w]hen playing decision lists/timelines in the authoring tool using Button 174 (invoking subroutine E), the user is the viewer of the content.” Pet. 49 (citing Ex. 1004, 6:40–45). Thus, Petitioner appears to contend that, during the process of creating a show structure, the creator is a viewer if the creator can view the edited content corresponding to a node as the show structure is being created. Here, Petitioner would satisfy the “viewer” aspect of the Microsoft court’s construction by pointing to a creator viewing a piece of the show structure during the creating step, although Escobar does not teach that the creator can vary the duration of content while viewing it or that durations can be varied while a show structure (as opposed to a node being created) is being displayed in the displaying step, as discussed in more detail below.” slip op. at 13

The show structure of nodes specifies the duration of any display,” but there is no durational requirement separate from the construction of “node.” See Ex. 1011, 2–13; Pet. 11–12; Prelim. Resp. 7. Third, we construe “interactively variable duration information,” which is recited in challenged independent claim 1, as well as challenged dependent claims 2 and 26, as “a parameter specifying how long a content is to be displayed by default before a subsequent content is displayed, where the viewer of the content can change the parameter.” Ex. 1011, 22–23; Pet. 13; Prelim.

      “distinction. See Ex. 2005 ¶ 30 (“Henley discloses a ‘video optimized stream server system 10,’ also referred to as ‘media streamer,’ for use by broadcasters to deliver content to end users, or viewers.”). In particular, Dr. Almeroth observes that, in Figure 1 of Henley, reproduced above, system controller 64 is illustrated graphically as connected to multiple user controls 65, but is shown connected only to a single display 66. Id. ¶ 31. This structure, in combination with Henley’s description of the drawing, leads Dr. Almeroth to conclude that user control 65 “corresponds to a ‘set top box[]’” for an end user, and that system controller 64 corresponds to a separate “‘user interface’ for the operator.” Id. Specifically, Dr. Almeroth points to Henley’s description of system controller 64 as “respond[ing] to inputs from user control set top boxes 65 to cause commands to be generated that enable media streamer 10 to access a requested video presentation.” Id.; Ex. 1013, 8:30–32 (emphasis added). Dr. Almeroth also notes Henley’s explanation that “[s]ystem controller 64 is further provided with a user interface and display facility 66 which enables a user to input commands, such as by hard or soft buttons, and other data to enable an identification of video presentations, the scheduling of video presentations, and control over the playing of a video presentation.” Ex. 2005 ¶ 31; Ex. 1013, 8:33–38. These disclosures by Henley support Dr. Almeroth’s conclusion that “[t]his ‘user interface and display facility 66’ is for an operator—not an end user.” See Ex. 2005 ¶ 31. Dr. Almeroth provides additional reasoning to support this conclusion. For example, Henley explains that “[s]ystem controller 64 responds to inputs from user control set top boxes 65 to cause commands to be generated that enable media streamer 10 to access a requested video presentation.” Ex. 1013, 8:30–32. In light of this, because an end user would interact with the set-top box shown as user control 65, Dr. Almeroth reasons that “it would make no sense” for display 66 to be for the end user. Ex. 2005 ¶ 32. We agree with this reasoning. In addition, Dr. Almeroth observes that Henley describes two types of interfaces for media streamer 10, a command line interface and a graphical user interface. Id. ¶ 33 (citing Ex. 1013, 18:47–50). Because the command line interface can be used for “batch” functionality, Dr. Almeroth reasons, and we agree, that the command line interface is for broadcast operators, rather than for end users. Id. With respect to the graphical user interface shown in Figure 8, reproduced above, Dr. Almeroth further reasons that a person of skill in the art would understand that it relates to operator controls, rather than end-user controls, because Henley specifically describes it as showing keys “used to operate the media streamer.” Id. ¶ 34; Ex. 1013, 4:5– 6. In other words, according to Dr. Almeroth, “[t]he graphical user interface corresponds to the command line interface.” Ex. 2005 ¶ 34. Dr. Almeroth’s reasoning is compelling. Notably, Figure 8 shows “Batch” button 130 and “Import/Export” button 132 to “move video data into and out of the media streamer.” See Ex. 1013, 19:20–22, 19:30–31. As Dr. Almeroth testifies, these are not functions that a person of ordinary skill in the art would understand to be available for end users, but are appropriate for broadcast operators: “None of these commands are consistent with those that would be available to an end user of, e.g., a set top box or pay-per-view system.” Ex. 2005 ¶ 35. In light of this compelling testimony, we agree with Patent Owner and find that “Henley . . . does not describe . . . the end user’s interface or controls.” See Prelim. Resp. 22.” slip op. at 24

The district court stayed the litigation “pending resolution of the IPR proceedings that have been instituted on the patents at issue in this case.” Ex. 2006, 2. Regarding the length of the stay, the district court explicitly ordered the parties not to use continuance of the fact discovery to October 28, 2022 “as grounds for . . . opposing institution of any post-grant proceeding.” Ex. 2007, 2. Regarding when the stay will be lifted, the order merely gives Patent Owner the opportunity to “seek to lift the stay as to any patents that are not instituted for review.” Ex. 2006, 2 (emphasis added). But we decline to speculate whether the district court would grant such a motion directed only to one of the six patents. Among the reasons warranting a stay of the litigation, the district court found “IPR has the potential to streamline issues for trial” and “the resources the parties will need to expend for experts could be significantly impacted by the outcome of any instituted IPR proceedings.” Id. Thus, the litigation is stayed pending the outcome of the six related proceedings, not merely the outcome of this institution decision, and the district court stayed the litigation for the explicit purpose of gaining efficiency and avoiding duplication of efforts by letting this inter partes review proceed to its conclusion first.14 See Prelim. Reply. 4–5. While Patent Owner may seek to lift the stay as to any patent for which institution is denied, the grant of any such request is uncertain. Accordingly, this factor strongly weighs against discretionary denial of institution.” slip op. at 15

    • Skill levelOther

      “Petitioner asserts that a person of ordinary skill in the art (POSITA) “would have at least a Ph.D. degree in chemistry, or a bachelor’s or master’s degree plus experience involving the use and design of fluorescent probes or dyes.” Pet. 17 (citing Ex. 1007 ¶¶ 14–18). Patent Owner agrees that a POSITA may have a Ph.D. degree or master’s degree in chemistry, but asserts that a POSITA would also have “some experience with fluorescence” in addition to a degree in chemistry and that the experience of a POSITA with a master’s degree in chemistry is alternatively “industry experience in the field of biological detection systems.” Prelim. Resp. 10 (citing Ex. 2001 ¶ 7). For purposes of this Decision, we need not choose between the parties’ proposed levels of one of ordinary skill in the art, which are quite similar, as neither party asserts that the anticipation or obviousness analyses in this case would turn on which definition is adopted. See Prelim. Resp. 10 (Patent Owner stating that its arguments and conclusions “would not change” if Petitioner’s definition were applied).” slip op. at 10

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Decided for patent owner

      “The express language of claim 1 requires no solubility threshold, and dependent claim 10 demonstrates that where a solubility threshold was intended by the inventors of the ’620 patent they knew how to expressly set forth that threshold in the claims. Compare Ex. 1005, 213:26–27 (“capable of imparting solubility in water”), with id. at 218:12–14 (“The method according to claim 1, wherein each R is a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.”). Thus, the claim language does not support applying a particular solubility threshold in claim 1. As noted by Patent Owner, the written description of the ’620 patent explains that “[i]n some embodiments, each R is independently a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.” Id. at 54:2–10; Prelim. Resp. 12–13. This solubility threshold, however, is not in claim 1, and we decline to import such a limitation from the written description into claim 1 absent compelling reasons for doing so. See SciMed Life Systems, Inc. v. Advanced Cardiovascular Systems, Inc., 242 F.3d 1337, 1340 (Fed. Cir. 2001) (explaining that “reading a limitation from the written description into the claims” is “one of the cardinal sins of patent law”); see also Thorner v. Sony Comp. Entm’t Am., LLC, 669 F.3d 1362, 1366 (Fed. Cir. 2012) (“It is likewise not enough that the only embodiments, or all of the embodiments, contain a particular limitation. We do not read limitations from the specification into claims; we do not redefine words.”). In view of the foregoing, we construe the term “non-ionic side group capable of imparting solubility in water” to not include any particular numeric solubility threshold.13” slip op. at 12
