“We disagree with Patent Owner that all of the references Petitioner is relying on are the same or substantially the same as references that were before the Office. In particular, there is no dispute that Miller was not considered by the Office. See Prelim. Resp. 6–13; Ex. 1001, code (56). Further, we do not agree with Patent Owner that Miller is substantially the same as Agboatwalla. Specifically, Petitioner relies on Miller for being able to select different types of communication tools for a group: Miller discloses a number of web-based forms that allow the user to (among other things) specify a name and description for the environment (Fig. 13B) identify the members of the environment (Fig. 13C, 14A-C), and select the various communication features (e.g. bulletin board, etc.) that will be available for members (Fig. 16). (Miller, 0045:12-0046:27.) With respect to the selection of communications features, Miller discloses a user interface for allowing the user to select (from a list) the environment. (Miller, Fig. 16, 0047:31-0048:9, 0042:29-32 (“The group creator selects from among these functions, preferably by way of an easy-to-use web browser interface, and these choices are stored in a database and associated with the group members.”).) These selections are then used in creating the environment or group.

Pet. 18–19 (emphasis added).11 We have reviewed the section of Agboatwalla to which Patent Owner directs us (Ex. 2003, 2:32–50) and do not see substantially the same functionality. Although Agboatwalla describes a user being able to select what content may be viewed (see id.), Patent Owner does not direct us to, and we do not see, Miller’s teaching of selecting different types of communication pathways that may be selected for a group. Accordingly, Miller is not substantially the same as Agboatwalla. 3. Conclusion Based on our consideration of Becton Dickinson factors (a), (b), and (d), we find that the same or substantially the same art or arguments were not previously presented to the Office. Thus, our analysis ends at this point, and we need not proceed to part two of the Advanced Bionics framework. See Advanced Bionics, IPR2019-01469, Paper 6 at 8.

“f) Conclusion Regarding Claim 1 Based on the current record, there is a reasonable likelihood that Petitioner will prevail in demonstrating that claim 1 is unpatentable as obvious in view of Neibauer, Miller, Cheng, and Squibbs. 6. Analysis of Claims 2–25 Because Petitioner demonstrates a reasonable likelihood of success in proving that at least one claim of the ’801 patent is unpatentable, we institute on all grounds and all claims raised in the Petition. See 37 C.F.R. § 42.108(a). Therefore, at this stage of the proceeding, it is not necessary for us to provide an assessment of every challenge raised by Petitioner, especially, as in this case, when Patent Owner does not separately argue those claims. Those challenges, in our view, are best left for trial after full development of the record.” slip op. at 32

“Based on the current record, the combination of Neibauer and Miller teaches “control[ling] activation of a mobile information channel,” as recited in claim 1. As discussed above, the first user can create a Yahoo! Club by supplying the necessary information and selecting “Yes! I accept.” Neibauer is silent on whether the user can select which specific mobile information channels are associated with the Yahoo! Club. However, Miller teaches a similar collaborative web-based system in which the group’s creator can use an interface to choose specific communication pathways to allow: FIG. 16 shows one possible user interface for selecting communication tools to be made available to group members. This screen can be presented to the user creating the environment after the group has been identified and its members selected. It is contemplated that a variety of communication tools can be provided, including a bulletin board service; advertisements; white pages (e.g., a listing of members, their e-mail addresses, telephone numbers, and the like); yellow pages (e.g., a listing of promotional and contact information); document security (e.g., shared access secure document storage services); anonymous e-mail (described above with respect to the first embodiment); threaded dialogs; a group newsletter creation tool; videoconferencing; and even other user-provided applications that can be specified by name an location (e.g., URL).

The combination of Miller’s teaching of selecting different methods of communication with Neibauer’s teaching of Yahoo! Clubs would allow the founder to select specific mobile information channels for the group to use. See Ex. 1002 ¶¶ 95–100. Based on the current record, a person having ordinary skill in the art would have combined those teachings in the manner described above. See Ex. 1002 ¶¶ 97–100.

“evidence. The challenged claims require that a sacrificial anode be placed within a certain distance—10 inches—of the hot liquid inlet, and, because the inlet has some non-zero size, it might be possible for an anode to be within that distance from some parts, but not from all parts, of the inlet. Accordingly, specifying the center axis of the inlet as the point from which to measure the distance to the anode improves on the plain words of the claim in terms of achieving the claim’s objective of placing the anode within a specified distance of the inlet. Moreover, when discussing the distance from the inlet to the anode, the specification of the ’494 patent uses the language “within 10 inches in any direction of the center axis of the inlet connection.” Ex. 1001, 7:61–64. Thus, the intrinsic evidence supports adopting Petitioner’s claim construction. Petitioner’s declarant, Dr. Medlin, relies on Petitioner’s proposed construction. See, e.g., Ex. 1004 ¶¶ 20 (noting that the construction “within 10 inches of the center axis of [a] hot liquid inlet” “ha[s] been adopted by Petitioner”), 96 (“the sacrificial anodes contained in each of the turbulators 2 would be placed within 10 inches of a center axis of a hot liquid inlet to the radiator of Tomosada”), 144 (“A POSITA would understand from Figure 1 that the sacrificial anode 14 is within 10 inches of a center axis of a hot liquid inlet”), 267 (“These teachings would further motivate a POSITA to located the sacrificial anode 12 within 10 inches of a center axis of the hot liquid inlet.”). This support for Petitioner’s proposed construction provides further reason for us to adopt it. Because it is supported by the intrinsic evidence of record, because Patent Owner proposes no alternative construction, and because Petitioner’s expert supports it, we adopt the construction of “within 10 inches of a hot liquid inlet to the radiator” that Petitioner proposes. Thus, we construe this term as “within 10 inches of the center axis of a hot liquid inlet to the radiator.” In other words, when discussing the distance between a hot liquid inlet and a sacrificial anode, we interpret “hot liquid inlet” as “center axis of the hot liquid inlet.”” slip op. at 5

“Inherency may be relied upon in arguing either anticipation or obviousness. Schering, 339 F.3d at 1377 (applying inherency in an anticipation context); Par Pharma. Inc. v. TWI Pharma., Inc., 773 F.3d 1186, 1195–96 (Fed. Cir. 2014) (applying inherency in an obviousness context). In both cases, however, “[t]he mere fact that a certain thing may result from a given set of circumstances is not sufficient.” Therasense, Inc. v. Becton, Dickinson & Co., 593 F.3d 1325, 1332 (Fed.

Instead, “the limitation at issue necessarily must be present, or the natural result of the combination of elements expressly disclosed by the prior art.” Par Pharma., 773 F.3d at 1195–96. Here, Petitioner has not shown sufficiently that, in Godefroy, the sacrificial anode necessarily is placed within 10 inches of the center axis of the hot liquid inlet. Dr. Medlin testifies that Figure 1 of Godefroy shows that “an entirety . . . or at least a significant portion of the sacrificial anode 14, is within 10 inches of a center axis of the inlet.” Ex. 1004 ¶ 144. But we cannot say that Figure 1 of Godefroy is clear on its face, or reasonably suggests, that this is necessarily the case. There are no dimensions shown on Figure 1, so it is unclear from the figure what the diameter of pipe 12 is. If that diameter is larger than 20 inches, then it simply is untrue that “sacrificial anode 14 is . . . necessarily placed within 10 inches of a center axis of a hot liquid inlet to the radiator,” as Dr. Medlin testifies. Id. ¶ 361. As noted above, neither Petitioner nor Dr. Medlin relies on the hot liquid inlet of Godefroy having any particular diameter, and Godefroy is silent as to the diameter of its inlet.

Prelim. Resp. 3–5; Exs. 2001–2003. In the absence of any testimony or other evidence that tends to show that radiator inlet pipes necessarily have diameters less than 20 inches, Petitioner has not shown sufficiently that the diameter of Godefroy’s inlet pipe is small enough to ensure that any portion of the anode necessarily is within 10 inches of the center axis of the inlet.” slip op. at 11

“As we understand it, one theory of obviousness advanced by Petitioner is combining Fugitt’s teaching that “[t]he rolls of the calender may be steam heated” with Papermaking’s teaching about the surface temperature that can be obtained when using steam to heat the rolls. Pet. 32–33; temperature of Fugitt’s steam-heated rollers in order to achieve a contact surface temperature of at least 250°F, as recited in claim 1. Instead, we understand Petitioner to be relying on Papermaking to teach the temperature of the unmodified rollers of Fugitt. Under this theory, it was not necessary for Petitioner to show that the paperboard substrate properties disclosed in Fugitt would still be achieved after increasing the temperature. Nevertheless, the Petition also relies on Papermaking’s teaching of temperatures that exceed the upper limit for steam-heated rolls, e.g., “[h]igh thermo roll temperatures (in some cases over 200°C [392°F]” or oil-heated rollers having surface that “can reach over 220°C [428°F].” Pet. 33 (citing Ex. 1005, 82; Ex. 1010, 98).

“Given this, to show that Blangero’s disclosure of MgO or LiF in its coating teaches or suggests a rock-salt crystal structure, Petitioner needs to explain why a person of ordinary skill in the art either would have understood the compounds to have a rock-salt crystal structure when manufactured according to the disclosure of Blangero or would have chosen to use MgO or LiF in a rock-salt crystal structure rather than in another available form. On the first point, Petitioner argues that “‘the stable phase at room temperature and pressure conditions’ of MgO is ‘a rocksalt cubic structure of NaCl (space group Fm-3m).’” Pet. 28 (quoting Ex. 1030, 16; citing Ex. 1003 ¶ 142). But, as Petitioner’s declarant, Dr. Hayes, points out, Blangero does not teach forming MgO in a room-temperature process. Ex. 1003 ¶ 142 (Blangero’s “second firing step” occurs at “925 °C for 12 hours”); see Ex. 1005 ¶ 110 (teaching the firing step to which Dr. Hayes refers). Thus, the significance of rock-salt-type MgO being “the stable phase at room temperature and pressure conditions” is unclear. To the extent that Dr. Hayes explains why MgO, which “is well known to crystallize even at substantially lower temperatures,” such as “room temperature and pressure conditions,” would “do so more readily at [a higher temperature of] 925 °C,” this argument is not discussed, nor even cited, in the Petition. Ex. 1003 ¶¶ 90–94; see Pet. 28. Accordingly, any reliance on this argument by Petitioner constitutes improper incorporation by reference. 37 C.F.R. § 42.6(a)(3). Thus, Petitioner does not show sufficiently that a person of ordinary skill in the art either would have understood MgO to have a rock-salt crystal structure when manufactured according to the disclosure of Blangero or would have chosen to use MgO in a rock-salt crystal structure rather than in another available form. Similarly, with respect to LiF, neither Petitioner nor Dr. Hayes sufficiently explains the choice of rock-salt-type material over other options. Pet. 29 (arguing only that Ex. 1013 shows that “LiF has rock salt structure”); Ex. 1003 ¶ 143 (same). Thus, Petitioner does not show sufficiently that Blangero teaches or suggests a rock-salt crystal structure by virtue of its teaching that either MgO or LiF is present.” slip op. at 12

“The 2012 study on which Petitioner relies did not find “superior structural stability” over other lithium-titanium-oxygen compounds, as Petitioner argues. Instead, the study noted that the structure of “LiTiO2 prepared by high-temperature sintering TiO2 with lithium salt . . . impl[ies] LiTiO2 has superior structural stability in organic electrolyte as compared to other Li-Ti-O oxides.” Ex. 1029, 1. Thus, the structural stability was implied from the chemical structure of the material rather than found through study of the material. Moreover, the implied structural stability was only for LiTiO2 that was prepared in a particular way, by high-temperature sintering of TiO2 with lithium salt, and Petitioner does not allege that a person of ordinary skill in the art would have prepared the LiTiO2 they substituted for Blangero’s Li2TiO3 using this method. As for Petitioner’s argument that the study found that LiTiO2 outperformed Li2TiO3, we are not persuaded. The study compared particles with an LiTiO2 coating to uncoated particles, not to particles coated with Li2TiO3. Ex. 1029, 4, Figs. 4(c), 4(d). Although the study notes that particles coated with “[m]onoclinic Li2TiO3 and spinel Li4Ti5O12” exhibit “a noticeable capacity decay . . . when charged at high operating voltage and cycled above room temperature,” it concludes only that particles coated with LiTiO2 “exhibited inspiring high-voltage cycling capability as well as thermal stability than the pristine counterpart.” Id. at 1, 4. In addition, the pristine particles used in the study were made from “Li[NixCoyMnz]O2 (0≤x,y,z<1) (called as LNCM),” and the particles in Blangero do not contain either nickel or manganese in their cores. Ex. 1005 ¶¶ 9–40 (particles contain lithium, oxygen, cobalt, and metals chosen from the group consisting of aluminum, gallium, boron, magnesium, titanium, iron, copper, calcium, barium, yttrium, tin, antimony, sodium, zinc, zirconium, silicon); Ex. 1029, 1. Petitioner does not explain why a person of ordinary skill in the art would expect the study’s results to extend to Blangero’s particles made from a different material. Pet. 29–30. Because Petitioner has not shown sufficiently that Blangero teaches or suggests a second region comprising a rock-salt crystal structure or that a person of ordinary skill in the art would have had a reason to substitute rocksalt-type LiTiO2 for the materials disclosed in Blangero, Petitioner has not shown a reasonable likelihood that it would prevail on claim 1 on its Blangero-based grounds.” slip op. at 15

“the claim must be given their plain meaning unless the plain meaning is inconsistent with the Specification. In re Zletz, 893 F.2d 319, 321 (Fed. Cir. 1989). Additionally, ordinary, simple English words whose meaning is clear and unquestionable are to be construed to mean exactly what they say–– absent, of course, any indication that their use in a particular context changes their meaning. Chef America, Inc. v. Lamb-Weston, Inc., 358 F.3d 1371, 1372 (Fed. Cir. 2004). The abstract of the ’646 patent describes isolating and preserving cells from bodily fluids “for cellular analysis” and “genomic studies.” Ex. 1001, code (57). In the field of the disclosure portion of the ’646 patent, cells isolated from bodily fluids are preserved “for studies in any of: functional genomic and epigenetic studies, and biomarker discovery.” Id. at 1:25–29. In the background section, the ’646 patent describes the interest in “large-scale epigenetic research” for the purpose of “understanding the mechanisms of gene-environment interactions” suggesting that “epigenetic mechanisms may provide a molecular memory of environmental experiences.” Id. at 1:60–67. The background section further describes the challenges of collecting bodily fluids, such as saliva, is that it is a digestive fluid that can be rich in proteases and that existing solutions used to stabilize cells from blood, which is a transporter fluid, “will not protect cells from proteases found in some bodily fluids, such as saliva.” Id. at 3:24–36, 4:43–47. The detailed description section of the ’646 patent discloses “a solution for preserving cells in one or more bodily fluids, such as saliva and urine” that “may be beneficial for further separation into cell types and downstream molecular analysis” and “allows for storage of cells in the bodily fluid to retain their antigenicity and cellular architecture.” Id. at 16:9–15. The Specification describes some embodiments of solutions for preserving cells in one or more bodily fluids where the solutions contain a chemical fixing agent, a protease inhibitor, an antimicrobial agent, serum proteins, and are buffered to preferred pH ranges. Id. at 16:15–22. Thus, the plain meaning of “preserving a biological sample,” consistent with the ’646 patent disclosure focused on maintaining the architecture of cells contained in a bodily fluid that may include digestive proteases for further study downstream, is “preserving the integrity of a cell contained in a bodily fluid sample.”” slip op. at 15

“The disclosures of the ’864 patent thus align with the Patent Owner’s position that the recitation of a “CO to CO2 combustion promoter” in claim 1 constitutes a claim limitation because the disclosures show that the phrase is “necessary to give meaning to the claim[s] and properly define the invention” as described in the patent. In re Fritch, 972 F.2d 1260, 1262 (Fed. Cir. 1992); see also Kropa v. Robie, 187 F.2d 150, 151–152 (CCPA 1951) (determining that a preamble reciting “an abrasive article” should be given patentable weight for a claim further reciting that the article comprised abrasive grains and a binder because “it is only by that phrase that it can be known that the subject matter defined by the claims is comprised as an abrasive article” in view of the fact that “[e]very union of substances capable inter alia of use as abrasive grains and a binder is not an ‘abrasive article.’”). The Patent Owner thus provides factual and legal bases for determining that a “CO to CO2 combustion promoter,” as recited in the preamble of claim 1, is a claim limitation. By not taking a position as to whether a “CO to CO2 combustion promoter” constitutes a claim limitation, the Petitioner does not establish that this recitation is not limiting. We determine that the intrinsic evidence of record is sufficient to establish that a “CO to CO2 combustion promoter” is a limitation of claim 1 because the evidence shows that this phrase is necessary to give meaning to the claim and to properly define the invention.
