    “Kwatra teaches, at Equation 7, minimizing velocity and acceleration of a function representing camera path (P). FF ¶¶ 6, 8–9. Kwatra does not state that this camera path function considers rotation. Rather, the words “camera path” suggest x, y, z movement of the camera rather than rotation of the camera. Dr. Foroosh’s testimony that Kwatra’s minimization of a smoothed camera path does not result in minimizing rotational velocity and acceleration is credible because this testimony is consistent with Kwatra as a whole and consistent with the other evidence of record. Id. ¶ 10. Kwatra recognizes that image rotation angle (“θ”) may not remain smooth. Id. ¶ 12. But rather than attempting to minimize velocity and acceleration of rotation of the camera housing, Kwatra states that applying a smoothness constraint on rotation angle “may be non-linear.” Id. ¶ 13. Consistent with Kwatra, Dr. Foroosh credibly explains the difficulty of applying linear techniques to rotation. Id. Thus, Kwatra proposes instead constraining the sine and cosine of theta. Id. ¶ 14. The Kwatra provisional application is part of the Kwatra reference (id. ¶ 15), and it similarly opts for simpler schemes rather than estimating all parameters for all frames jointly. Id. ¶ 16. The provisional explains that the rotational component is relatively small such that non-linear computations minimizing velocity and rotation can be avoided. Id. ¶¶ 17–18. The testimony of Patent Owner’s witness, Dr. Foroosh, explaining the provisional is credible (Ex. 2018 ¶ 72) because it is consistent with Kwatra’s complete disclosure. Dr. Foroosh’s testimony is more credible than the testimony of Petitioner’s witness, Dr. Katsaggelos, because Dr. Katsaggelos did not review the Kwatra provisional application and, thus, did not review the entire disclosure of Kwatra.

    “We review this testimony based on the strength of the underlying factual basis. 37 C.F.R. § 42.65(a); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value . . ..”). Here, the underlying factual basis is not very strong for either witness. That said, we find that Dr. Foroosh’s testimony is more logically sound and consistent with the ’840 patent disclosure. Based on our reading of the specification, we find a clear indication that “stickiness” has to do with the past. In order to control “the extent by which preceding portion(s) . . . impacts determination of the smoothed trajectory” (emphasis added), one must control the degree by which the past frames impact determination. And to control the degree of the past’s influence, one must, as a consequence, favor the past over the future. That is, the frame of reference of the stickiness parameter is the past. The specification could have used a time-agnostic term, like a “nearness” or “adjacency” parameter, but it did not. Thus, the fact that “stickiness” is used in conjunction with “preceding” indicates that it deals with a preference for preceding frames. On this basis, we find Dr. Katsaggelos’s testimony less persuasive than Dr. Foroosh’s.” slip op. at 10

    “That said, we do not construe a stickiness parameter as prohibiting consideration of future frames. Instead, we determine that the stickiness parameter’s value determines the impact of the preceding portions, versus the following portions. The ’840 patent recognizes this, when it says that a stickiness parameter value of “1,” representing a “lazy” stabilizer that maximally favors the past, would not override a violation of the margin constraint based on the look-ahead (i.e., would not allow the viewing window to fall out of bounds in the event of large future motion). See Ex. 1001, 22:26–30; see also id. at 12:61–13:29 (acknowledging that favoring the past may lead to a conflict with the viewing window determination), 15:39–60 (adjusting the viewing window to ensure it does not violate a margin constraint). Thus, while a past-favoring parameter by necessity favors the past over the future, it does not prohibit consideration of the future. In view of the above, we construe the claimed “stickiness parameter” as a parameter that controls the extent by which preceding portions of the trajectory impacts determination of the smoothed trajectory, with an understanding that in order to favor preceding portions, to some extent, the parameter must relatively disfavor following portions.” slip op. at 10

    “Given the teachings of the specification, we agree with Patent Owner that a low-light high-pass parameter is a parameter of a smoothing function that favors high frequencies (high pass) when exposure times are long (low light). See Tr. 42:10–18 (Patent Owner’s counsel stating that “high-pass” means “there’s a bias or preference for high frequencies”); Ex. 2020, 93:23– 94:15 (Petitioner’s declarant, Dr. Katsaggelos, agreeing that a high-pass system attenuates the low frequency of a signal). Although we acknowledge Petitioner’s position that the specification provides other ways or considerations in implementing a smoothing function, based on our above analysis of the specification, we find that the specification describes the lowlight high-pass parameter as a specific component of a smoothing function. See, e.g., Ex. 1001, 21:17–25 (setting out several parameters besides the low-light high-pass parameter used in trajectory smoothing).” slip op. at 10

    “position and a real device position. Id. at 18:27–40. In other words, the blur is addressed by analyzing the image to identify motion and then shifting the image. Shi, however, does not disclose how its parameter is based on low light (or the long exposure times indicative of low light). In its Petition, Petitioner asserts that a person of ordinary skill in the art would understand that “blurs can be caused by low light conditions.” Pet. 28 (citing Ex. 1003 ¶ 111). Although this is true, that does not mean that Shi’s blurs are identified by a parameter that considers low light. As we just described, Shi identifies the blur by quantifying the amount of motion of the points in an image, not by identifying low light. This is simply a different way to determine the presence of motion blur. In Shi, blur is measured, whereas in the ’840 patent, it is inferred based on low-light conditions (e.g., by observing the exposure time). See, e.g., Ex. 1007, 18:7– 26; Ex. 1001, 19:12–26. In its Reply, Petitioner does not point to any further disclosures. Accordingly, we find that Shi does not disclose the “low-light” aspect of the claimed low-light high-pass parameter. This is sufficient to determine that Petitioner’s ground does not meet all claim limitations. Similarly, we find that Shi does not disclose the “high-pass” aspect of the parameter. Shi’s blur compensation uses a spherical interpolation to modify the image. Ex. 1007, 18:27–40. The low-light high-pass parameter, as we have construed the term, allows more high frequencies. To allow more high frequencies, this necessarily means either allowing fewer low frequencies, or allowing more high frequences as opposed to some counterfactual situation in which fewer high frequencies were going to be allowed. See Ex. 2020, 94:23–95:15; Ex. 2022. We are directed to no persuasive evidence from Petitioner that Shi’s spherical interpolation favors high frequencies over low frequencies. Accord Ex. 2018 ¶ 107 (Patent Owner’s expert stating that Shi’s spherical interpolation “reintroduce[es] both high- and low-frequency motion”). Even if Shi allows the viewing window to track the camera position “consistent with the natural blur in the image” (Ex. 1007, 17:63–67), we are not provided with sufficient evidence to conclude by a preponderance of the evidence that providing a similar visual goal as a high-pass parameter (Ex. 1001, 22:16–18, “the output motion may include high frequencies that mask motion blur”) is the same as having a high-pass parameter. Again, merely preserving high frequencies is not the same as having a “high-pass parameter” because, as construed, a “high-pass parameter” also involves some degree of attenuation of low frequencies or relative increase of high frequencies. Accordingly, we find that Shi does not disclose the “high-pass” aspect of the claimed low-light high-pass parameter.” slip op. at 18

Asserting that “Mauer teaches providing sufficient network coverage by use of different kinds of networks, network interfaces, and protocols,” Petitioner contends that a person of ordinary skill in the art would have recognized that “Waylett discloses an inexpensive way to implement the same networks used in Mauer’s WWAN 14 and WLAN 12.” Id.

Pet. 28. To support its inherency argument, Petitioner relies on knowledge in the art, i.e., the availability of the entire map of the LCR region, and the availability of restriction enzymes, including BstX1, SnaBI, BamHI, HindIII, and BanII. Id. at 39–40 (citing Kennametal, 780 F.3d at 1381–83). Based on that combined information, Petitioner contends that a POSA would “have been able to map all of the possible restriction sites in the regions flanking the cores of HS2, HS3, and HS4.” Id. Petitioner asserts further that “[g]iven the May Article’s disclosure regarding the size and location of TNS9’s HS2, HS3, and HS4 fragments, a POSA would have placed these fragments onto the restrictionsite map of the LCR” that was available at the time, and would have identified only six possible combinations of restriction enzyme fragments, including the one recited in claim 1. Id. Upon closer inspection, however, we appreciate from the testimony of Petitioner’s declarant, Dr. Bungert, that the process involved in arriving at those six possible combinations is predicated on numerous assumptions guiding a number of exacting steps to be performed in order to achieve the the claimed LCR fragment would have involved the steps of (a) placing fragments that are the disclosed size of the HS2, HS3, and HS4 fragments from the TNS9 vector in the May Article onto the known restriction-site map of the LCR; (b) comparing those fragments to the “‘drawn to scale’ map” in the May Article; and then (c) identifying various fragments and determining which ones are consistent with the May Article’s description and match up with the fragments on the May Article’s drawn to scale map. Ex. 1002 ¶¶ 143–156. To identify the fragments consistent with the May Article’s description, it was necessary for Dr. Bungert to use certain assumptions that exclude unfavorable enzymes, such as using a range of ± 20 bp in order to identify fragments with lengths that are within 20 bp of the fragments reported in the May Article. Id. In view of the number of assumptions and steps required to get from what is disclosed in the May Article to arrive at the alleged “six possible LCRs (i.e., combination of HS2, HS3, and HS4 fragments based on the TNS9 LCR disclosed in the May Article)—including the LCR recited in claim 1,” Ex. 1002 ¶ 156, we do not find that Petitioner has demonstrated that fragments having the restriction sites recited in claim 1 would have been “at once envisaged” by a skilled artisan as argued by Petitioner.

Thus, the May Thesis represents the work of one of the ’179 inventors and is therefore ineligible as prior art under 35 U.S.C. § 102(a) for challenged claims 1, 19, and 22. See, e.g., In re Katz, 687 F.2d 450, 454–455 (CCPA 1982) (a prior publication by inventors or a subset of the inventors does not qualify as prior art under 102(a)). With respect to 35 U.S.C. § 102(b), we find that the May Thesis is ineligible as prior art, even assuming that claims 1, 19, and 22 are not entitled to receive benefit of an earlier filing date. Petitioner provides evidence that the May Thesis was publicly available as of November 26, 2001. Pet. 17 (citing Ex. 1036 ¶¶ 1–26; Ex. 1002 ¶ 60). Patent Owner does not dispute that evidence. Based on the undisputed November 26, 2001 public availability date, the May Thesis represents a disclosure less than one year before the asserted effective filing date, i.e., the July 1, 2002, for claims 1, 19, and 22 challenged with this reference. Based on that timing and because the disclosure was made by the inventor, the May Thesis is not available as prior art to challenged claims 1, 19, and 22 under 35 U.S.C. §102(b).

    “summarized above, we determine that the May Article fails to disclose the restriction sites surrounding the BstXI and SnaBI HS2-, BamHI and HindIII HS3-, or BamHI and BanII HS4-spanning nucleotide fragments, as required by the challenged claims. According to Petitioner, that limitation is inherently disclosed by the May Article’s description of the lengths of the HS2, HS3, and HS4 fragments in the TNS9 vector and its depiction of those fragments on a map of the LCR. Pet. 28. To support its inherency argument, Petitioner relies on knowledge in the art, i.e., the availability of the entire map of the LCR region, and the availability of restriction enzymes, including BstX1, SnaBI, BamHI, HindIII, and BanII. Id. at 30–31 (citing Kennametal, 780 F.3d at 1381–83). Based on that combined information, Petitioner contends that a POSA would “have been able to map all of the possible restriction sites in the regions flanking the cores of HS2, HS3, and HS4.” Id. Petitioner asserts further that “[g]iven the May Article’s disclosure regarding the size and location of [TNS9’s] HS2, HS3, and HS4 fragments, a POSA would have placed these fragments onto the restrictionsite map of the LCR” that was available at the time, and would have identified only six possible combinations of restriction enzyme fragments, including the one recited in claim 1. Id. Upon closer inspection, however, we appreciate from the testimony of Petitioner’s declarant, Dr. Bungert, that the process involved in arriving at those six possible combinations is predicated on numerous assumptions guiding a number of exacting steps to be performed in order to achieve the claimed LCR fragment. According to Dr. Bungert, the process for making the claimed LCR fragment would have involved the steps of (a) placing fragments that are the disclosed size of the HS2, HS3, and HS4 fragments from the TNS9 vector in the May Article onto the known restriction-site map of the LCR; (b) comparing those fragments to the “‘drawn to scale’ map” in the May Article; and then (c) identifying various fragments and determining which ones are consistent with the May Article’s description and match up with the fragments on the May Article’s drawn to scale map. Ex. 1002 ¶¶ 112–117. To identify the fragments consistent with the May Article’s description, it was necessary for Dr. Bungert to use certain assumptions that exclude unfavorable enzymes such as using a range of ± 20 bp in order to identify fragments with lengths that are within 20 bp of the fragments reported in the May Article. Id. In view of the number of assumptions and steps required to get from what is disclosed in the May Article to arrive at the alleged “six possible LCRs (i.e., combination of HS2, HS3, and HS4 fragments based on the TNS9 LCR disclosed in the May Article)—including the LCR recited in claim 1,” Ex. 1002 ¶ 117, we do not find that Petitioner has demonstrated that fragments having the restriction sites recited in claim 1 would have been “at once envisage[d]” by a skilled artisan as argued by Petitioner.

    “We are not persuaded by Petitioner’s contention that we should disregard Dr. Naumovski’s testimony because she may have taken a leave of absence from work for a couple of years. The record supports that Dr. Naumovski not only meets the requirements of the person of ordinary skill in the art, but also appears to have relevant knowledge with respect to Gynostemma pentaphylum (“GP”) saponins. See Ex. 2015 (Appendix A). related field, and at least two years of experience using techniques for extraction and characterization of plant-based materials.” PO Resp. 11 (citing Ex. 2015 ¶ 74). Because there are more than 400 species of plants that contain saponins, Patent Owner disagrees that a person of ordinary skill in the art would be familiar with the structure and utility of saponins. Id. The level of skill in the art is a reference point for gauging what would have been obvious based on the reference disclosures. See Okajima, 261 F.3d at 1355. In other words, the lens of the level of ordinary skill in the art does not change a prior art’s disclosure, though it may change one’s understanding of what is disclosed. Patent Owner, however, does not explain how its definition provides a reference point that would meaningfully alter the Petition’s assertions of obviousness. For purposes of this decision, we analyze the asserted prior art with respect to the level of skill set forth by Petitioner, but there would be no difference in the outcome of this Decision if we were to apply the level of skill in the art set forth by Patent Owner.

Illumina Cambridge Ltd., 821 F.3d 1359 (Fed. Cir. 2016) (explaining that the expectation of success issue involves a showing of “a reasonable expectation of achieving what is claimed”) (emphasis added). Here, Petitioner relies on Kim 460 to show that heating ginseng, which contains the ginsenosides Rb1, Rb2, Rc, Rd, Rg3, and Rg5, results in a teaches that ginseng with the higher Rg3 and Rg5 content is 50-fold more potent in their vasodilation studies than the non-treated samples. Razmovski teaches that G. pentaphyllum contains over 100 saponins and eight of those saponins are the same as protoparaxadiol-type ginsenosides Rb1, Rc, Rb3, Rd, F2, Rg3, malonyl-Rb1, and malonyl-Rd that are found in P. ginseng. Ex. 1007, 4. Knowing that G. pentaphyllum also contains ginsenosides Rb1, Rb2, Rc, Rd, Rg3, and Rg5, we find Petitioner’s conclusion that heating a G. pentaphyllum extract that contains these ginsenosides would similarly increase the ginsenoside levels of Rg3 and Rg5 is a reasonable inference from the cited references. Based on the teachings in Kim 460, we agree with Petitioner that it would have been reasonable to expect that the same source material, although derived from a different plant, would behave similarly to heat treatment. See Pet. 24. Because G. pentaphyllum is a less expensive starting material, we also agree with Petitioner that there is sufficient motivation to substitute G. pentaphyllum for ginseng in the methods of Kim 460. slip op. at 29

    “Also, the Petition merely states that “Ono supports instances where the user stops the step-counting mode operation using switch S2 after the processor detects that” the target distance or the target number of steps has been reached and notifies the user by generating an alarm sound. Pet. 53 (emphasis added). In this case, supporting the notion of the user stopping the step-counting mode operation in response to the alarm is not the same as teaching or suggesting the notion to one of ordinary skill in the art. The possibility that a user could stop the step-counting operation in response the alarm is insufficient to render claims 1 and 20 obvious to one of ordinary skill in the art.

    “focused split sample typically would not allow two cells to arrive at the inspection region at once, because there is not enough space for two 10-μm cells to travel side by side.” See Ex. 1054 ¶ 21 (citing Ex. 1005, 5662) (emphasis added). The qualifier “typically” for two cells not arriving at the same time does not indicate that there would be no split stream. And Dr. Issadore seems to concede there could be a split sample. Id. Further, Dr. Issadore does not state which dimensions of which of Simonnet’s channels that he is using as a reference.27 We determine that Dr. Issadore provides insufficient evidence and reasoning for an understanding that there would be a single stream if mammalian cells were used, in addition to making a statement that stops short of that conclusion. Although not argued by Petitioner nor discussed by Dr. Issadore, Simonnet does state: “we expect the HTD to be compatible with cells up to ~15 µm in size.” Ex. 1005, 5662. Simonnet also states: “We expect that with the improvements in optics and detection electronics, a cytometry system based on the HTD would match the throughput, sensitivity, and accuracy of commercial flow cytometers and would be an adequate tool for assaying fluorescently marked live cells.” Id. These statements can be fairly read as a statement of reasonable expectation of success of using mammalian cells in the device. However, Simonnet is silent as to whether the mammalian cells would be in a single stream, and if anything, Simonnet appears to be inviting further experimentation. Accordingly, Petitioner has not provided adequate reasoning to modify Simonnet to form a single sample stream.” slip op. at 52

    “sheath flow does not mean that “focusing” requires sheath flow. In other words, the Specification does not contain a definition of “focusing” that defines “focusing” as requiring “sheath flow.” As discussed above, the Specification does state “focusing (e.g., constricting).” See also Tr. 41:22– 42:8 (discussing the Specification of the ’439 patent). Whether or not this disclosure rises to the level of a definition, it indicates that focusing is understood to be constricting and does not mention “sheath flow.” Although sheath flow may, in certain cases, be a natural result of having multiple fluid focusing features (see Ex. 1001, 14:6), the claim itself does not require that focusing include sheath flow.11 11 In terms of resolving the dispute between the parties, the real question appears to be whether the sample stream that exits the focusing region must be a single sample stream or whether it may encompass split sample streams, a question that we address in the next subsection. Patent Owner’s ultimate argument appears to be that “focusing” requires a single sample stream because “focusing” requires sheath flow and sheath flow requires a single sample stream. However, we agree with Petitioner that persons of ordinary skill could still refer to split streams as having “sheath flow” (see Ex. 1054 ¶ 11; Ex. 1043, 2215, Fig. 10 and caption (“separated two-sample 3D sheath flow”); Ex. 1044, 2 (“multiple core-sheath flow”), and therefore, even if we agreed with Patent Owner that focusing requires sheath flow, that would not clarify whether “focusing” precludes split sample streams. In any event, we conclude that focusing does not require sheath flow. We recognize that there are examples in the Specification where there is sheath flow. E.g., Ex. 1001, 5:30–32 (“Certain embodiments described herein relate [to] systems and methods for producing a sheath flow . . .”), 10:35–37 (“The illustrated core stream forming geometry 400 provides improved sheath flow capabilities and thus improved sample focusing capabilities.”). However, case law generally counsels against importing limitations from the Specification into the claims. See, e.g., Phillips v. AWH Corp., 415 F.3d 1303, 1323 (“To avoid importing limitations from the specification into the claims, it is important to keep in mind that the purposes of the specification are to teach and enable those of skill in the art to make and use the invention and to provide a best mode for doing so.”).12 We, therefore, do not import “sheath flow” into the definition of focusing.” slip op. at 16

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
