We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses or teaches these limitations because the evidence does not provide support that there is remote control of fluid handling devices or the use of a user command on a control interface to send a command to a fluid handling device, for instance. Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but we do not discern that it teaches or discloses the capability to remotely control fluid handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, the Kahn disclosures that Petitioner repeatedly relies upon for allegedly teaching this control are deficient.

Communication unit 112B is part of the local “sensor unit,” wherein the detection conditions determined by the sensor are communicated to remote devices by communication unit 112B. See id. at 3:31–33, 5:62–6:2, 6:27–35, 7:33–37, 13:7–12, Figs. 1A–1C. Kahn discloses that the sensor units, which include communication units 112B, can be located near shut-off valves and can communicate with distant locations. See id. at 11:1–13. There are no disclosures, however, in the above passages that there is remote control of fluid handling devices, that there is a user command on a control interface that actuates an actuator, or that there is a command sent to the facility actuators via a network connection, as required in limitations [18.5]–[18.7] and [18.9]–[18.12], respectively.

As Petitioner and its expert explain, a person of ordinary skill in the art would have been motivated to modify Figure 5 of Alie into a BSI device because BSI devices allow more incident light to reach the semiconductor layer, resulting in more light being absorbed, an increase in the quantum efficiency, and an improvement in the signal to noise ratio.

Petitioner further proposes that “[m]ore education can supplement practical experience and vice versa.” Id. (citing Ex. 1003 ¶ 56). In its Preliminary Response, Patent Owner does not take a position on the relevant level of ordinary skill in the art. See generally Prelim. Resp. At this stage of the proceeding and on the present record, we adopt Petitioner’s uncontested proposed level of ordinary skill in the art, which we find consistent with the level of ordinary skill in the art reflected by the ’651 patent and the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).” slip op. at 9

The Board denied institution on all challenged claims because the same claims, grounds, arguments, and evidence had already failed the reasonable-likelihood threshold in the Samsung IPR, and denied joinder.

“35 U.S.C. § 315(c), which states as follows: JOINDER.— If the Director institutes an inter partes review, the Director, in his or her discretion, may join as a party to that inter partes review any person who properly files a petition under section 311 that the Director, after receiving a preliminary response under section 313 or the expiration of the time for filing such a response, determines warrants the institution of an inter partes review under section 314. Because joinder under 35 U.S.C. § 315(c) is premised on an inter partes review having been instituted, and the Board did not institute review in the Samsung IPR to which Petitioner seeks to join, we deny the Motion for Joinder.” slip op. at 3

“At this preliminary stage, we determine whether the information presented shows a reasonable likelihood that Petitioner would prevail in establishing that at least one of the challenged claims would have been unpatentable over the proposed prior art.

“B. Level of Ordinary Skill in the Art As noted above, resolving the question of obviousness requires determination of the level of ordinary skill in the art. Graham, 383 U.S. at 17–18. 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. The absence of such assessment calls into question the fundamental adequacy of Petitioner in carrying its burden to show a reasonable likelihood of success of unpatentability of the challenged claims that necessarily must take into account the level of ordinary skill in the art.” slip op. at 10

“In any event, we do not discern that there is any apparent dispute between the parties as to the meaning of any claim term.

“A POSITA would have been motivated to modify Summers’ fiber optic cable 50 to include Kaji’s intermittently-fixed optical fiber tape 2A to obtain the predictable result of enabling a higher density of optical fibers to be packed in Summers’ fiber optic cable 50, as contemplated by Kaji. *** a POSITA would have had a reasonable expectation of success because such modification would amount to nothing more than a simple substitution of Summers’ four-fiber ribbons 52 with Kaji’s intermittently-fixed optical fiber tape 2A by known methods of cable manufacturing. ***” slip op. at 20
