Pet. 11 (citing Ex. 1005 ¶ 48).

“specification explicitly includes sensors similar to those in the prior art in support of their argument that the claimed “predetermined cycle” must not exclude the use of such sensors. Pet. Reply 15 (citing Ex. 1001, 32:55–33:7, 40:66–41:5, 44:9–29). We reviewed the portions of the specification cited by Petitioner. We agree with Patent Owner that one excerpt discussing sensor use appears to be directed to triggering the predetermined cycle rather than causing timing changes during the cycle itself (Ex. 1001, 32:55–66) (describing use of a pressure sensor to “determine when the vacuum channel 3 is clogged by a thrombus and automatically perform the unclogging procedures described herein”), while another excerpt discusses a sensor that Petitioner that the ’402 patent discusses the use of sensors to “tune” the system and that such “tuning” can be done statically (setting the cycle timing in advance) or dynamically (adjusting the timing during the cycle itself). See Ex. 1001, 48:19–49:50. Overall, we find that these disclosures involving sensors demonstrate that sensors may be used in various ways in different embodiments. However, none of these disclosures explicitly discuss the use of sensors in conjunction with a “pre-determined cycle.” Therefore, we find that the ’402 patent specification’s discussion of “sensors” are not particularly informative as to the appropriate construction of a “predetermined cycle” and do not outweigh the other explicit disclosures of “predetermined cycle” in the patent. We next turn to the other intrinsic evidence discussed by the parties — the prosecution history. As discussed by Patent Owner, in the Notice of Allowance, the Examiner found that Garrison did not teach or suggest a “predetermined cycle” because Garrison’s controller “changed the cycle of opening and closing the valves based on feedback from sensors.” Ex. 1004, 86. We acknowledge that the patent applicant filed subsequent comments during prosecution in which they stated that they “do[] not concede that the Examiner’s characterizations of the terms of the claims and the prior art are correct.” Id. at 29. However, we agree with Patent Owner that the importance of the Examiner’s statement in the Notice of Allowance does not rely on it being an express disclaimer (a standard which it does not meet). PO Sur-reply 8. We also considered Petitioner’s contention that the Examiner’s interpretation of Garrison may have been in error (PO Resp. 16); however, even if this were true, the Examiner’s statement still provides helpful insight into how the Examiner was interpreting the term sensors to change the opening and closing of valves during a cycle was not a “predetermined cycle.” Id. at 86. In sum, we find that Patent Owner’s proposed construction is consistent with the usage of the term “predetermined cycle” in the ’402 patent specification and prosecution history. Thus, after considering all of the cited evidence, we construe “predetermined cycle” to mean that “the timing of the sequence of valve operations in the cycle is determined beforehand, i.e., fixed, rather than varying based on feedback after operation begins.”” slip op. at 14

“2. Other Terms The parties also provided proposed constructions for the limitations of “[limited/limiting] to a positive amount of exit flow” and “control[ling] fluid flow in and out from the distal end of the catheter.” See Pet. 15–16; Pet. Reply 1–8; PO Resp. 22–24; PO Sur-Reply 2–6. However, having evaluated the arguments and evidence before us, we determine that construction of these terms is not necessary for purposes of this Decision. See Nidec Motor Corp. v.

“We agree with Patent Owner that neither Petitioner nor Mr. Brown propose any combination of Yang and Mullins that does not include Mullins’s pressure sensor in order “to control fluid flow in and out from the distal end of the catheter.” Indeed, in addressing the “predetermined cycle” limitation, Mr. Brown contends that Mullins discloses a “cycling controller that ‘varies aspiration pressure according to sensed pressure within the catheter lumen.’” Ex.1005 ¶¶ 131–32 (citing, e.g., Ex.1008, 27:40–28:20 (“[a] novel aspect of this pump system is the incorporation of feedback into the pump algorithm in order to produce more effective pressure cycling”)). This use of a sensor to change pressure during a cycle, is not a “predetermined cycle” under our construction. combinations is its discussion of distal end flow control, not for its sensors.” Pet. Reply 17 (citing Ex. 1035 ¶ 83). However, Petitioner’s obviousness grounds rely on the combination of Yang and Mullins, especially with regard to Mullins’s disclosure of “a controller” in order “to control fluid flow in and out.” As discussed above, Mullins relies on the sensor-feedback approach in order to control flow and we find that Petitioner has not presented persuasive evidence of how the combined disclosures of Yang and Mullins would control flow without using Mullins’s sensor feedback approach. See W.L. Gore & Assocs., Inc. v. Garlock, Inc., 721 F.2d 1540, 1550 (Fed. Cir. 1983) (error to “consider[] … references in less than their entireties, i.e., in disregarding disclosures in [them] … that diverge from and teach away from the invention”). Therefore, we determine that Petitioner has not sufficiently shown that the combination of Yang and Mullins discloses or renders obvious “a controller configured to open and close the vacuum valve and the vent valve in a predetermined cycle to change a level of vacuum at the distal end of the catheter and to control fluid flow in and out from the distal end of the catheter.” Accordingly, having considered the parties’ respective evidence and arguments, we find that Petitioner has not shown by a preponderance of the evidence that claim 1 of the ’402 patent would have been unpatentable as obvious over the combination of Yang and Mullins.” slip op. at 27

“appear to be that Patent Owner specifies that the POSA’s knowledge and experience may include optical sensors and that the POSA may have a degree emphasizing software. We do not deem these differences material, particularly because the optical sensors and technologies at issue are those used in physiological monitoring technologies and both parties agree that the POSA would have a working knowledge of physiological monitoring technologies. Ex. 1003 ¶ 24; PO Resp. 11. We find the additional specificity of Patent Owner’s definition to be helpful. In addition, Patent Owner’s definition appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosure of the ’507 patent. Accordingly, we adopt Patent Owner’s proposed definition of the person of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Our inability to find a teaching of averaging in Mendelson is consistent with the testimony of Drs. Kenny and Duckworth.

See Ex. 1087, 103:9–114:11 (confirming that certain aspects of his declaration testimony relating to averaging of signals are not discussed in Mendelson).

That is not, however, the standard for inherency. It must be the necessary result, not a possible expected result. The Federal Circuit in Par explained that: Inherency, however, may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient. If, however, the disclosure is sufficient to show that the natural result flowing from the operation as taught would result in the performance of the questioned function, it seems to be well settled that the disclosure should be regarded as sufficient.” slip op. at 28

“C. Claim Construction In an inter partes review proceeding, a patent claim is construed using the same standard used in a civil action under 35 U.S.C. § 282(b), including construing the claim in accordance with the ordinary and customary meaning of the claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b). Neither party proposes an express construction for any claim terms. Pet. 5; PO Resp. 9. We determine that no claim terms require an express construction to resolve the parties’ disputes regarding the asserted grounds of unpatentability. See Sections II.D–II.F.” slip op. at 6

“Patent Owner’s arguments are unavailing. Grotmol teaches that a user may train a robot to learn “simple” and “complex” tasks. Ex. 1005, 24:17– 23. The evidence of record indicates that a person of ordinary skill in the art would have known to use different trainers “to train behaviors involving different levels of complexity in order to take advantage of the varying skills and knowledge of trainers.” Ex. 1003 ¶ 341. Thus, based on Grotmol’s teaching that a robot can learn both simple and complex tasks, a person of ordinary skill in the art would have had a specific reason for different users to train Grotmol’s robot for different behaviors, namely, to benefit from the users’ varying skills and knowledge. Pet. 25; Ex. 1003 ¶ 341; Ex. 1005, 24:17–23. Grotmol also teaches that a user may train a robot “using a gamepad (or other input device . . . ).” Ex. 1005, 26:9–13; see id. at 33:18–21. The evidence of record indicates that “switching users would be as simple as handing off a gamepad or other remote device used for controlling the robot from one user to another.” Ex. 1010 ¶ 73. Neither Patent Owner nor its declarant, Dr. Eli Saber, explains specifically why handing Grotmol’s gamepad to a different user would have created “complexities of combining the mixed knowledge into a single knowledgebase” or required “identifying each user to store particular learned operations and preferences in portions of the knowledgebase for user-specific autonomous operations.” See PO Resp. 14–15; PO Sur-reply 9; Ex. 2007 ¶¶ 128–130. Thus, based on Grotmol’s teaching of using a gamepad to train a robot, it would have been simple and straightforward for different users to train Grotmol’s robot for different behaviors. Ex. 1005, 26:9–13, 33:18–21; Ex. 1010 ¶ 73.” slip op. at 12

“4. Reason to Combine Petitioner asserts that a person of ordinary skill in the art would have had reason to combine the cited teachings of Grotmol and Hickman. Pet. 27–30 (citing Ex. 1003 ¶¶ 159–166). We agree with Petitioner’s rationale. Specifically, it would have been obvious to a person of ordinary skill in the art to combine Grotmol and Hickman so that Grotmol’s robots share training sets using Hickman’s shared robot knowledgebase. Id. at 30; Ex. 1003 ¶ 166. Doing so would have been obvious because Grotmol teaches sharing training sets between robots, and Hickman’s shared robot knowledgebase would facilitate wider and faster sharing of Grotmol’s training sets. Pet. 27–29; Ex. 1003 ¶¶ 160–161, 164; Ex. 1005, 33:27–32; Ex. 1007, 1:38–41, 5:41–46, 11:31–41. In addition, a person of ordinary skill in the art would have had a reasonable expectation of success in using Hickman’s shared robot knowledgebase with Grotmol’s robot because Hickman’s shared robot knowledgebase would “not interfere” with Grotmol’s robot.

“The parties appear to agree that the term “connection” refers to a relationship, but dispute whether it includes a link. PO Resp. 7; Pet. Reply 23. We need not resolve this claim construction issue in order to resolve the parties’ disputes about the asserted ground of unpatentability. Specifically, as discussed below, even if we assume for the purposes of this Decision that the term “connection” means a “relationship that includes a link,” the asserted prior art still discloses the disputed claim limitation.

“We agree with Patent Owner that claim 15 requires modifying the first instruction set before determining the modified first instruction set based on an at least partial match between the new digital picture and the first digital picture. Claim 15 recites “modifying: the first one or more instruction sets” and “determining the modified the first one or more instruction sets . . . based on the at least partial match between the new one or more digital pictures and the first one or more digital pictures.” Ex. 1001, 162:65–163:15 (emphasis added). The phrase “the modified . . . instruction sets” in the determining limitation indicates an order because it refers back to the instruction sets modified in the modifying limitation. Id. Further, the phrase “based on the at least partial match” indicates that a partial match between the new picture and the first picture returns the modified first instruction set. Id. In order for a partial match to return the modified first instruction set, it is logical that the first instruction set previously was modified and correlated to the first picture. Id. Thus, claim 15 indicates that the modifying limitation is performed before the determining limitation. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369 (Fed. Cir. 2003) (“First, we look to the claim language to determine if, as a matter of logic or grammar, [the recited steps] must be performed in the order written.”).” slip op. at 8

“We agree that Petitioner’s obviousness rationale appears to be based on the challenged patent’s disclosure—at least in part. See Pet. 46–47 (citing Ex. 1001, 1:25–50), 61 (citing Ex. 1001, 2:34–40). Dr. Mark P. Mahon’s corresponding testimony relies on the same parts of the challenged patent, adding little additional technical reasoning or support from the prior art of 8 Petitioner cites “Section 5.8a.1.3.”, but the quoted passage appears in Section 5.8.1.3. Pet. 60 (emphasis added). challenged patent itself raises the possibility that Petitioner has succumbed to impermissible hindsight bias. See Zoltek Corp. v. United States, 815 F.3d 1302, 1313 (Fed. Cir. 2016) (citing KSR Int’l Co. v. Teleflex, Inc., 550 U.S. 398, 421 (2007)) (discussing the “the distortion caused by hindsight bias”); see also InTouch Tech., Inc. v. VGO Commc’ns, Inc., 751 F.3d 1327, 1351 (Fed. Cir. 2014) (“It appears that [the expert] relied on the . . . patent itself as her roadmap for putting what she referred to as pieces of a ‘jigsaw puzzle’ together.”). Even so, the preliminary record also indicates that it may be inherent in an NB-IoT system that “DCI indicating an SC-MCCH change notification must be transmitted in a different subframe from the DCI indicating a resource for the updated SC-MCCH information.” Pet. 61.

“We see no basis for using China Standard Time here. “The time and date of receipt of an application filed via EFS-Web is the local time and date in USPTO headquarters in Alexandria, Virginia.” Manual of Patent Examining Procedure (MPEP) § 502.05 I.C.2 (9th ed. Rev. 07.2015, Nov. 2015) (emphasis added).7 The MPEP provides an example of how an application filed from the Pacific Time Zone would receive the filing date as of the USPTO’s local time: For example, if an applicant in California officially files a patent application with the USPTO through EFS-Web by clicking on the SUBMIT button at 10 p.m. Pacific Time in California on May 1, that application would be officially received by the USPTO at 1 a.m., local time (i.e., Eastern Daylight Time) on May 2. Accordingly, the application would receive a filing date of May 2. Id. Thus, we disagree with Patent Owner’s argument that Fujishiro is not prior art for this reason. Prelim.
