    “distinct from “comminute[ion],” Petitioner offers only the testimony of its expert, Mr. Juzkow, who equates Tomioka’s “cutting” with “comminute[ion].” See Ex. 1003 ¶ 121. However, Mr. Juzkow provides insufficient reasoning to support his conclusion, particularly given the intrinsic and extrinsic evidence discussed above. In contrast, Patent Owner’s expert, Mr. Dantam, provides extensive reasoning, supported by citations to other evidence, to support his conclusion that Tomioka’s “dismantling” is not the claimed “comminution.” Thus, we give more weight to Mr. Dantam’s testimony than Mr. Juzkow’s testimony. Weighing this evidence all together, we find that Petitioner has failed to show that it is more likely than not that Tomioka’s teaches the claimed comminution under Petitioner’s first theory.” slip op. at 15

    “obvious. Pet. 34–35. However, we agree with Patent Owner that Petitioner has also failed to show that it is more likely than not that Tomioka renders this limitation obvious. See Prelim. Resp. 28–31. To begin with, Petitioner’s contentions lack sufficient reasoning explaining why a person of ordinary skill would have modified Tomioka in the manner proposed. “[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). Petitioner merely asserts that a person of ordinary skill in the art could use the roller system in place of the dismantling disclosed for the embodiments in Figures 19 and 20. On this record, we find this bare contention insufficient. actual disclosure of Tomioka. The rollers in Tomioka are used to separate the “battery body” from the “resin package enclosing the battery body,” and Tomioka specifically discloses that this technique is designed to “avoid damaging the battery body.” Ex. 1005 ¶¶ 25, 26, 29; Ex. 2011 ¶¶ 72–73. Thus, there is a significant difference between what Tomioka teaches and what Petitioner proposes to use the roller system to do. In addition, as Patent Owner points out, Tomioka specifically discloses there are risks associated with mechanically crushing battery packs, such as “risk of sparking due to residual voltage if the battery units are damaged in the process.” Ex. 1005 ¶ 5. Although we do not agree with Patent Owner that this amounts to a “teaching away,” see In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994), we do believe that this teaching suggests a trade off that should be weighed in determining whether to make the modification, see Medichem S.A. v. Rolabo S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). However, Petitioner has failed to account adequately, if at all, for this trade off. Thus, we find that Petitioner has failed to show that it is more likely than not that Tomioka accounts for the claimed “comminuting.”” slip op. at 15

Here, however, as Patent Owner observes (Prelim. Resp. 10), 8 Patent Owner does not present arguments or evidence of secondary considerations in its Preliminary Response. Therefore, secondary considerations do not constitute part of our analysis herein. Petitioner has provided no assessment as to the level of ordinary skill to be considered in evaluating the grounds of obviousness that are advanced by Petitioner.

    “Accordingly, the ’202 patent consistently and repeatedly characterizes the invention as incorporating tobacco in some form and ties the stated benefits of the invention to the inclusion of tobacco. Moreover, the Specification is directed to smoking articles containing tobacco, all of the embodiments include tobacco, and “the present invention” is described as a smoking article, where the smoking article includes tobacco. Consequently, we determine that “smoking article” as it is used in the challenged claims is limited to devices that include tobacco. See Mosaic Brands, Inc. v.

Patent Owner directs us to a statement in the prosecution history that “[a] lateral transistor is a transistor in which current flows across ‘in the direction parallel to’ the device surface,” as opposed to “a vertical transistor,” in which “[c]urrent ‘flows in the direction normal to’ the device surface.” Prelim. Resp. 8 (quoting Ex. 1002, 33–34). Thus, the parties generally agree that a lateral transistor is a transistor in which current flows in a direction parallel to the surface of the transistor. Petitioner argues that Nega teaches or suggests a transistor in which current flows parallel to the surface because Nega’s source, gate, and drain electrodes “are spread laterally in a lateral drift path, instead of vertically stacked.” Pet. 24–25 (citing Ex. 1005, Fig. 2). Patent Owner argues to the contrary that the placement of source, gate, and drain electrodes in the same lateral plane, rather than in a vertical stack, does not necessarily indicate that the current flow within the transistor is parallel to the surface. Prelim. Resp. 47–48 (citing Ex. 2002, 7–8, Figs. 1.7a, 1.7c). According to Patent Owner, transistors with electrodes in the same horizontal plane can have either lateral or vertical current flow. Id. Thus, Patent Owner argues, the lateral placement of the source, gate, and drain electrodes in Nega does not mean that Nega teaches or suggests a lateral transistor. On the present record, we agree with Patent Owner that Petitioner has not shown sufficiently that Nega teaches a transistor in which current flows in a direction parallel to the surface, rather than in a direction normal to the surface. Transistors with current flow in either direction can have electrodes located on a common horizontal plane, with the direction of the current flow depending on the configuration of doped semiconductor regions located below the electrodes. Ex. 2002, Figs. 1.7a, 1.7c.

    “We agree with Patent Owner. The ’350 patent distinguishes between user authentication using a username and password and application of a security policy. Ex. 1101, 1:35–39 (“A first level of access control is achieved by requiring authentication of a user. This may be accomplished by requiring the user to enter a username and a password.”), 1:45–48 (“Reliance on mere user authentication includes several disadvantages. For example, there are no provisions to assure that an access device used by the authenticated user meets network security policies.”). Although the ’350 patent describes both user authentication and application of a security policy as being carried out by a gatekeeper, this is accomplished in separate process steps. Id. at 10:38–41 (“GateKeeper 225 authenticates a user, obtains audit data, and applies a security policy in an Authenticate User Step 440, an Obtain Audit Data Step 450 and an Apply Security Policy Step 460, respectively.”).

    “As Patent Owner shows, the specification reveals that in step 762, “the routine ‘control’ computes an output value p corresponding to the currently selected strength, stored in the variable strength, and outputs the value p to the power supply so that the power supply outputs an appropriate current to the coil.” Id. at 15 (emphasis added) (quoting Ex. 1001, 8:20–30). Step 762 corresponds to, for example, control input 624 transmitted from CPU 602 to power supply 612 of Figure 6 to control the current from power supply 612 to coil 626. See supra Section II.C (describing Fig. 6); Ex. 1001, 6:41–44 (“The power supply 612 receives a control input 624 from the CPU to control the current supplied to the H-bridge switch 618 for transfer to the coil 626.”). The specification, therefore, supports Patent Owner. The specification clearly links this algorithmic structure to the recited function, “controlling supply of power from the power supply.” As Patent Owner shows, Petitioner agreed in the Sony litigation that the corresponding structure includes “provide a corresponding output to the power supply so that the power supply provides a corresponding output to the driving component and equivalents thereof.” Prelim. Resp. 12–13 (quoting Ex. 2001, 12–14).” slip op. at 16

    “The record supports Patent Owner. Under a means plus function analysis, which the parties agree applies, Petitioner relies on Houston’s microprocessor as the structure that corresponds to the recited “control component.” Pet. 36 (“Houston teaches that vibration controller 623 is a microprocessor thereby satisfying the structural requirement of this means plus-function limitation.”). microprocessor, limitation 1.f further requires algorithmic structure (processed by the microprocessor of the recited “control component”) to include “1) computing a digital output value corresponding to user-selected amplitude of oscillation and outputting the value to the claimed power supply so that the power supply outputs an appropriate current amplitude to the coil.” Supra Section III.C (emphasis added). In other words, as Patent Owner argues, to satisfy limitation 1.f, the “prior art [at least] would need to have this microprocessor perform the algorithmic step of ‘provid[ing] a corresponding ‘output to the power supply.’” Prelim. Resp. 18. Patent Owner also argues that “[t]he Petition fails to show that this [algorithmic step] is disclosed or rendered obvious by the combination of Houston and Goldenberg.” Prelim. Resp. 18. The record supports Patent Owner. Petitioner does not contend, let alone show, that the combination of Houston and Goldenberg teaches outputting any value to a power supply as limitation 1.f requires according to the claim construction Patent Owner argues and we adopt. See Pet. 35–42; supra Section III.C. It follows that the Petition fails to show a reasonable likelihood of success of prevailing with respect to claim 1.” slip op. at 23
