    “IV. PATENT OWNER’S MOTION TO EXCLUDE Patent Owner seeks to exclude portions of Dr. Wieselthaler’s Declaration (Exhibit 1041), portions of Mr. Crosby’s Reply Declaration (Exhibit 1042), portions of the deposition transcript of Dr. Wieselthaler (Exhibit 2028), and the exhibits “upon which that testimony is based” (Exhibits 1015, 1038, 1044, 1046, 1049, and 1050). Mot. 1. According to Patent Owner, the Motion was made “to preserve objections previously made in the record.” Id. (citations omitted). Patent Owner did not timely move to strike any of the evidence at issue as being outside the scope of reply evidence. Patent Owner asserts that because an inter partes review must be based on prior art consisting of patents or printed publications (citing 35 U.S.C. § 311(b)), the testimony of Mr. Crosby and Dr. Wieselthaler concerning “various physical devices allegedly known” to a person of ordinary skill in the art is inadmissible, along with all of the exhibits (consisting of printed materials such a journal abstracts, press releases, and papers) related to those physical devices. Id. at 3–4; see also Mot. Reply 1–4 (arguing that “devices that Petitioner’s witnesses assert were in public use prior to the claimed inventions, are not prior art that can form the basis of an inter partes review”). According to Patent Owner, Dr. Wieselthaler was unable to “link two of these physical devices to the printed prior art asserted in this [inter partes review], but those attempts fell apart during his cross examination.” Id. at 4. Patent Owner further reasons that because the evidence “cannot be the basis” of an inter partes review, it “has probable,” “is irrelevant and not admissible,” “presents substantial danger of confusing the issues, causing undue delay, and wasting time in this trial,” and “are not ‘based on sufficient facts[,] the product of reliable principles and methods[, or] ‘a reliable application of the principles and methods to the facts of the case.’” Id. at 7 (citing Fed.

With regard to Exhibits 1015, 1038, 1044, 1046, 1049, and 1050, Petitioner argues, and we agree, that Patent Owner identifies no plausible legal theory for their inadmissibility based on the contention that they discuss physical devices. See Mot. Resp. 3. We also agree with Petitioner that the exhibits are not “the basis for any ground” asserted in this proceeding, and may be properly relied upon by Dr. Wieselthaler and Mr. Crosby as support for their rebuttal testimony directed to Patent Owner’s arguments disputing Petitioner’s asserted motivation to combine the prior art relied upon in the instituted grounds.

    “‘electronics for power and control’”). According to Mr. Crosby, a person of ordinary skill in the art “would have understood based on the disclosure of this setup that these speed and motor parameters were monitored by a sensor providing feedback to the controller.” Ex. 1003 ¶ 725. Mr. Crosby identifies no support for this opinion, which we give little weight to. The mere fact that Bourque’s pump used software to control speed and motor parameters does not show that Bourque used “one or more sensors” to provide feedback signals to the external control unit. Indeed, Petitioner fails to identify any evidence that Bourque used any “sensor” to monitor “speed and motor parameters.” Mr. Crosby also states that “[e]ach of the ‘ultrasonic flow probe’ and the ‘solid-state catheter-type pressure transducer’ described in [Bourque] is a ‘sensor’ as recited in Claim 33 that provides feedback signals to the external control unit (e.g., ‘electronics for power and control’ and ‘data acquisition’).” Id. ¶¶ 581, 726. Mr. Crosby’s opinion is again unsupported by the evidence, because, as explained above, there is no teaching in Bourque that either the “ultrasonic flow probe” or the “pressure transducers” used in the “in vitro characterization” studies were part of the heart assist pump device. Based on our review and consideration of Petitioner’s arguments and evidence directed to claim 11, we find that Petitioner has not shown by a preponderance of the evidence that the asserted combination of Bourque and Wampler teaches or suggests each of the limitations of dependent claim 11. We reach the same conclusion for the same reasons with regard to claim 33.” slip op. at 48

Evid. 702 serves “a ‘gatekeeping role,’ the objective of which is to ensure that expert testimony admitted into evidence is both reliable and relevant.” Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1360 (Fed. Cir. 2008). There is no question that the disputed testimony of Dr. Wieselthaler and Mr. Crosby is relevant to the asserted motivation to combine and reliable, only whether it becomes “not relevant” or “unreliable,” in light of limited scope upon which grounds of unpatentability may be based under 35 U.S.C. § 311(b), because the testimony is based on, or supported by, knowledge of physical devices and publications discussing physical devices. Patent Owner directs us to no support for the notion that an expert’s testimony in an inter partes review must be limited to only the prior art relied upon as grounds for unpatentability and may not take into account any knowledge of, or publications concerning, other “physical devices” that would have been known to a person of ordinary skill at the relevant time.

We recognize that Petitioner appears to raise the argument that “non-prior art evidence” may be relied upon by an expert, but Petitioner also fails to identify what evidence it is referring to and that argument was not responsive to any issue Patent Owner raised in the Motion. See Mot. Resp. 5.

    “in these respects. The preambles of claims 17 and 59 recite the “audio device wearable by a user for storing locally generated audio.” There is neither mention of “multi-track” audio in the claim, nor is the audio device limited to capturing a single source of sound, such as a single performer. Accordingly, we are not persuaded that the ’443 and ’207 patent claims support the limited scope that Patent Owner urges for the term “locally generated audio.” None of Patent Owner’s citations to the specification define or require that the “locally generated audio” correspond to audio generated only by a single performer. See, e.g., 230 IPR, Ex. 1001, 8:59−62 (stating that the local audio input device “may be worn by the performer and connects to local audio device 102 at local audio input device port 314”). Patent Owner’s argument that the specification “teaches a single creator/performer per local audio device” is well-taken, but the teachings do not indicate the intent to exclude other sounds from being captured at the local audio device (or indicate how the device would prevent the capture of other sounds, such that the audio would be “isolated” as Patent Owner contends). See 230 Sur-Reply 10 (citing 230 IPR, Ex. 1001, 4:28−32, 10:29−34, and Insituform Techs., Inc. v. Cat Contr., Inc., 99 F.3d 1098, 1105 (Fed. Cir. 1996) (“[C]laim 1 refers to ‘a cup’ and ‘the cup’ repeatedly, suggesting that only one cup is involved . . . . [N]either the specification nor the drawings disclose the use of more than one cup.”)). For instance, the specification describes that the “independent track of audio is received from one of the performer’s local audio device 102.” 230 IPR, Ex. 1001, 10:33−34. Thus, in this description the audio track corresponds to the audio captured by a particular audio device—which was worn by the performer— but does not limit that captured audio to only sounds made by the performer. As to the “local audio data” term, Patent Owner argues that “audio data” means “mono or stereo audio files created from independent, isolated locally generated audio files, such files suitable for creation of a multi-track audio file.” 230 PO Resp. 9−10 (citing Ex. 2140 ¶¶ 131, 134). This argument is unsupported by the claim language or specification. The claim does not require the creation of audio files, much less a “multi-track audio file.” The specification describes storing audio files in memory without the specificity that Patent Owner urges we adopt. See 230 IPR, Ex. 1001, 13:1−14. Accordingly, we are not persuaded by Patent Owner’s proposed construction of “local audio data.” Rather, we understand “audio data” to have a plain and ordinary meaning, such as the one given to the term by the District Court in the underlying litigation. 230 IPR, Ex. 1037, 10. We adopt the District Court’s construction of “audio data” to mean “data comprising audio signals in digital form.” Id. This finds support in the specification as the audio is described as being converted into digital audio and stored in a file. See 230 IPR, Ex. 1001, 13:1−14.

    “E. Level of Ordinary Skill in the Art Based on the argument and evidence presented in the Petition and Patent Owner’s preliminary response, we determined, as stated in our Decision on Institution, that “a person of ordinary skill in the art would have had a Bachelor’s degree in electrical engineering and two or more years of experience working with audio and wireless communications systems.” 230 Dec. on Inst. 16; 232 Dec. on Inst. 22−23. Patent Owner reiterates its position that a person of ordinary skill the art would have had “a bachelor’s degree in electrical engineering or a related subject and two to five years’ experience working with multi-track audio and wireless communications systems in the professional performance industry.” 230 IPR, PO Resp. 6−7 (emphasis added) (identical passage in 232 PO Resp. 8). Thus, the dispute centers on whether the level or ordinary skill includes specific work experience with multi-track audio in the professional performance industry. We do not agree that this specific work experience is necessary to the level of ordinary skill in the instant proceedings. In determining whether an invention would have been obvious at the time it was made, we consider the level of ordinary skill in the pertinent art at the time of the invention. Graham v. John Deere, 383 U.S. 1, 17−18 (1966). “The importance of resolving the level of ordinary skill in the art lies in the necessity of maintaining objectivity in the obviousness inquiry.” Ryko Mfg. Co. v. Nu‑Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991). The “person of ordinary skill in the art” is a hypothetical construct, from whose vantage point obviousness is assessed. In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). In determining the level or ordinary skill, we may consider various factors including “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, 57 F.3d 1573, 1579, (Fed. Cir. 1995) (quoting Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986)). Patent Owner’s proposed specificity of work with multi-track audio in a professional performance industry is not supported by the record. First, Patent Owner submits conclusory declaration testimony of James DeFilippis—repeating verbatim, and without any supported reasoning, Patent Owner’s proposed level of ordinary skill.

Petitioner does not explain how this cited reference evidences that one of ordinary skill in the art would have understood “magneto coupling” requires rotating permanent magnets. At most, this reference teaches an example device that provides “magneto coupling.” See Ex. 1011, 1. In sum, we agree with Patent Owner that “magneto coupling,” consistent with our Institution Decision, encompasses generating a rotating field either by rotating magnets or by an electromagnet / stator.

    “ignores the readily apparent fact that the lower arrow is placed in a location that misrepresents the minimum distance between the magnetically driven rotor and the second magnetic device to suggest that Wampler teaches “the second magnetic device positioned axially closer to the first magnetic device than to the magnetically driven rotor,” as required by claim 1. Petitioner purports to justify this misrepresentation by asserting that “the vast majority of the impeller 74 is spaced significantly farther apart from the stators 90 and 94 than the magnetic pieces 88 are positioned from the stators 90 and 94.” Id. at 33–34. Claim 1 does not recite any feature based on the “vast majority” of a component and it is readily apparent from Petitioner’s own annotated version of Figure 11a that the distance from both the “motor magnets [88]” and “impeller 74” to the “circular electromagnetic stator[s] [90 and 94]” is the same. We agree with Patent Owner that Petitioner has provided a “misleading Figure with two red arrows denoting measurement distances to illustrate its incorrect view that the second magnetic device is farther from the magnetically driven rotor than from the first magnetic device.” PO Resp. 13–15 (providing an annotated version of Wampler’s Figure 11a with an orange arrow showing that in Wampler the distances from the second magnetic device to both the rotor and the first magnetic device are the same).

That resulted in a sharp bend in the flow before it enters the impeller. To minimize the losses in this transition, the flow is slightly accelerated through this elbow. that this type of elbow [i.e., the elbow used with Bourque’s centrifugal pump] was unnecessary,” applying Wampler to Bourque would have improved “blood flow.” Pet. 73 (citing Ex. 1003 ¶¶ 418–419; Ex. 1007, 402; Ex. 1008 ¶¶ 75–76). As explained above, Wampler does not teach that “this type of elbow” was unnecessary. Bourque uses a centrifugal pump with an additional elbow specifically so that the centrifugal pump may be oriented “in the least obtrusive position.” Ex. 1007, 402. Moreover, there is no persuasive evidence to support Petitioner’s assertion that eliminating the elbow from Bourque would improve “blood flow.” Mr. Crosby’s declaration provides no additional explanation or support to show how “blood flow” would have been improved. See Ex. 1003 ¶ 419. Nor does Mr. Crosby address the fact that Bourque expressly states that “flow is slightly accelerated” through the elbow to “minimize losses in this transition.” Ex. 1007, 402. Eliminating the elbow from Bourque, as Petitioner and Mr. Crosby propose, would mean the pump could no longer be placed in “the least obtrusive position” according to Bourque and there is no persuasive evidence that such a modification would improve blood flow.” slip op. at 45

    “Based on the entirety of the trial record, we do not agree with Patent Owner’s reading of either the claims or the prior art because Patent Owner takes too narrow a view of both. First, based on the plain language of Porreca, we find it uses a combination of the sequence reads of the target sequence and differentiator tag sequences to determine whether there is duplication. See Ex. 1006 ¶¶ 139–140, 143, 148, 153. All that the claim requires is that the method identifies sequence reads with identical identifier and target sequences as duplicates. Because claim 1 contains the transition “comprising,” the claim is still satisfied if the category of identified duplicate reads contains identical labels and also contains more. Patent Owner admits that the identifier and target sequence do not have to be used simultaneously. Tr. 46:16–48:4. Instead, Patent Owner challenges whether Porreca uses the required elements in combination as recited in the challenged claims. Based on the record before us, we agree with Petitioner’s position especially in view of the open-ended nature of the claims and Patent Owner’s own admission that there is no temporal requirement for the use of target sequences and differentiator tag sequences. Specifically, we find that Porreca teaches using the combination of the target sequences and the differentiator tag sequence to determine whether particular sequence reads are unique or PCR duplicates. See Ex. 1006 ¶¶ 139–140, 143, 148, 153. The use of both such sequences meet the claim limitations. This finding is consistent with the prosecution history of the ’357 patent and how the applicant and examiner interpreted the claims. See Ex. 1013, 69–70, 78–79. Second, we find the disclosure of Porreca sufficient to demonstrate to an ordinarily skilled artisan that “collapsing” is done by comparing target sequences and differentiator tag sequences. Porreca specifically explains that: after multiple reads have been collected for a given locus, it is possible that due to bias (e.g., caused by PCR amplification steps), a large fraction of the reads are derived from a single originating molecule. This would skew the population of target sequences observed, and would affect the outcome of the genotype call.” slip op. at 30

    “We do not agree with Patent Owner for at least two reasons. First, Patent Owner fails to address the fact that Schmitt cites to McCloskey 2007. We find that the citation of McCloskey 2007 in Schmitt indicates that the ordinarily skilled artisan would have considered the teachings of McCloskey to be highly relevant to the teachings of Schmitt and would have considered them to be both useful in the field of sequencing. See Ex. 1005 ¶ 6. Second, Patent Owner fails to explain or even identify the purported structural differences between Schmitt and McCloskey that would prevent the teachings of McCloskey from being relevant to Schmitt. In addition, we credit the testimony of Dr. Metzker that one of ordinary skill in the art would have understood the benefits of adding a barcode to target sequences and would have looked to McCloskey and the batch-stamps it teaches because both Schmitt and McCloskey are in the same field and address the same problems. See Ex. 1003 ¶¶ 110, 114.

Motivation to Combine Becerra and Couckuyt Petitioner argues that a person of ordinary skill in the art would have been motivated to combine the teachings of Becerra and Couckuyt because such a person would have recognized that Couckuyt discloses useful techniques of assigning data to Becerra’s charts, including assigning data to each axis. Pet. 34 (citing Ex. 1005 ¶¶ 19, 52, Fig. 5; Ex. 1003 ¶ 224).

Petitioner’s annotations to Figure 4 identify “Drop Zones” in red and “Data Fields” in Blue. Id. at 36. Petitioner contends Couckuyt discloses a “drag-and-drop user interface (DDUI) . . . associated with a data source, such as the two-dimensional data source 300,” and Figure 4 illustrates the DDUI permitting “value data fields and the characteristic data fields . . . to be dragged and dropped into drop zones.” Id. at 35–36 (citing Ex. 1006, 7:10–13). Petitioner contends that a “primary benefit of the charting DDUI is that the user can quickly change the data that is being presented in the chart,” and using Couckuyt’s techniques, a user can “quickly change the data” and see the desired effects. Id. at 36 (citing Ex. 1006, 1:18–19; Ex. 1003 ¶ 228). Petitioner contends that when Becerra’s control panel includes multiple charts, Couckuyt’s techniques would allow dragging-anddropping data from a data source to multiple charts, and would simplify the process of assigning data to multiple control panel components. Id. at 36–37 skill in the art would have also had a reasonable expectation of success combining Becerra with Couckuyt because the combination would amount to nothing more than incorporating Couckuyt’s well-known drag-and-drop techniques into Becerra’s system.

According to Patent Owner, a person of ordinary skill in the art would not have been motivated to merely select data fields that do not limit the selected data in any way. Id. Patent Owner further argues Becerra’s method of binding components to a spreadsheet range and extracting formulas from a spreadsheet teaches away from the multiple chart generation scheme of Couckuyt that uses drag and dropping of data fields. Id. at 37. According to Patent Owner, Couckuyt is directed to the need for a charting DDUI that can generate multiple charts at the same time and such a need does not exist in Becerra which in turn is focused on creating a control panel that is an interactive graphics simulation.
