At the institution stage, we did not see a material difference in the proposals given that both parties also indicate that more education could substitute for less experience and vice versa, and thus adopted Patent Owner’s proposal. Inst. Dec. 9. We requested that the parties address during trial if either believed that the choice of one proposal over the other would make a difference in the patentability analysis. Id.

Pet. 9; Ex. 2015; Ex. 2025, 31–47. Instead, the district court adopted a “plain-and-ordinary meaning” construction, which Patent Owner proposed.

    “In our Institution Decision, we stated that we “will give the term ‘signal path’ its ‘plain and ordinary meaning’ and not limit it only to analog components, as the district court found and the parties agree.” Inst. Dec. 11. Given that the parties continue to agree on this point, we see no need to depart from the construction we adopted in our Institution Decision. Moreover, applying Revvo, we find that Petitioner had a sufficient reason for advancing the broader, court-adopted construction in this IPR for the same reasons as discussed above. In this proceeding, the dispute between the parties concerns the application of this and the surrounding claim language (i.e., “in the receiver signal path,” “in the signal path”) to the disclosures in Behbahani. See PO Resp. 43–45. Therefore, we will provide further discussion in the context of the parties’ arguments regarding Behbahani below. However, we agree with Patent Owner’s plain reading of the claim language to the extent it requires adjusting an impedance and/or bias current of a circuit while it is in the signal path.

    “Patent Owner’s arguments generally fail to address why Behbahani’s Variable Bandpass Filter Block does not teach the recited “plurality of circuits [comprising/including] . . . a filter,” and instead focus on why the low-pass and high-pass filter circuits do not teach the limitation, which is not Petitioner’s position. As stated above, we agree with Patent Owner’s plain reading of the claim language – i.e., that it “requires adjusting the bias, in or of a circuit.” See PO Resp. 49. However, Patent Owner’s reading of the claim does not persuasively address why the Variable Bandpass Filter Block does not teach the recited “circuit.” We have reviewed Dr. Larson’s cited testimony and disagree with Patent Owner that he provided “a well-supported opinion . . . as to why a [person of ordinary skill in the art] would not understand the entire bandpass box to be a single ‘circuit,’ or to reflect variation in ‘an impedance’ or ‘a bias’ in the claims.” Sur-reply 4 (citing Ex. 2020 ¶¶ 46–48, 71, 74–83). Dr. Larson testifies that the ’330 patent (which has the same specification as the ’164 patent) “teach[es] these adjustments [that dynamically change operating parameters] as changes effected in a single circuit block.” Ex. 2020 ¶ 46 (citing, e.g., Ex. 1001, Figs. 8A, 9A, 8:20–25, 8:36–39, 9:36–59, 10:1–18 (emphasis added)). Dr. Larson does not provide further explanation as to what he means by a “single circuit block,” but relies on Figures 8A and 9A, which show a “function block,” and other disclosures referring to a “function block.” See id. There is no dispute that the recited “circuit” in the receiver signal path is referring to these “function blocks.” See Tr. 22:20–23:4. The ’164 patent states that Figure 8A, which includes function block 820, is “an embodiment of the present invention” 8:28–30. Similarly, Figure 9A, which includes function block 920, “illustrate[s] one of the possible power saving techniques.” Id. at 3:41–42. The ’164 patent describes that “[f]unctional block 820 . . . may be a filter, mixer, amplifier, or other circuit or circuits in a wireless transceiver or other electronic circuits or system.” Id. at 8:30–33 (emphasis added). Based on these disclosures, we are not convinced that Function Block 820 or 920 cannot include multiple filters in a Variable Bandpass Filter Block, or that Behbahani’s Variable Bandpass Filter Block does not teach the recited “circuit.” Dr. Larson also relies on Figure 6 of the ’164 patent to conclude that” slip op. at 45

    “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged.

First, we agree with Petitioner that the ’641 patent indicates that the charge cut-off voltage selected for a particular battery need not be a fixed property of the battery or something that is set by the design and chemistry of the battery.

    “measurement by sensor 9 is not affected by “scattered reflected light” due to “dirty cover glass 19”). Moreover, even if fog or snow might make the cover glass “dirty” nothing in Karlsson senses that. Instead, the reference simply explains that the switching of the light is helpful if the glass happens to be dirty. Sensor 9 is used to detect light, such as from oncoming vehicles, not fog or snow (see Ex. 1010, 9:9–26), and none of the other passages of Karlsson cited in the Petition describe sensing fog or snow. Petitioner does not identify anything in Harbers that senses fog or snow, and we do not find a description of that ourselves. Harbers describes adjusting the light based on vehicle velocity, the position of the steering wheel, “weather conditions,” or road type (e.g., motorway or country road). See Ex. 1011, 3:27–4:32. It seems reasonable to assume that the velocity and position of the steering wheel are sensed, and the reference indicates that light distribution for road type can be adjusted “by the driver.” Id. at 4:22–25. The reference is silent, however, on how the adjustment based on “weather conditions” is made. Dr. Jiao cites a passage from Braun about how its “headlights . . . are programmed . . . to detect fog and . . . provide light appropriate for driving in fog” (see Ex. 1003 ¶ 590), but Braun is not included in this ground in the Petition (see Pet. 3), and neither Petitioner not Dr. Jiao attempts to provide a reason to combine Braun for these claims. We conclude that, in order to show that these claims would have been obvious, Petitioner would have needed to show that sensing would have been disclosed or inherent in the Harbers/Karlsson combination, obvious in view of Karlsson and Harbers, or that it would have been obvious to add Braun’s fog detection to the Karlsson/Harbers combination. As Petitioner did not argue an express or inherent disclosure of fog/snow sensing in Harbers/Karlsson, did not argue that it would have been obvious to use fog/snow sensing in the Karlsson/Harbers combination, and did not include Braun in the combination, we conclude that Petitioner has not shown that claims 29 and 69 are unpatentable” slip op. at 26

    “This argument is not persuasive because, we conclude, it overstates the problem. These claims require bluish light towards the center and yellowish light to the side.

Were the oncoming vehicle then moved to straddle the yellow and blue areas, the corresponding yellow and blue lights would be dimmed. And if the vehicle were to move to the blue area, the corresponding blue lights would be dimmed. We agree with Dr. Jiao that one of ordinary skill in this art, which is fairly predictable, would be able to avoid or sufficiently minimize any color shifting problems. See Ex. 1051 ¶¶ 162–165. We also credit Dr. Jiao’s explanation that, in the combination, there would only be “subtle variations of illuminated color within the range, such as bluish white and yellowish white” and that “all light would be recognized as white light (as defined in standards and regulations)” that not would be problematic in practice.

    “As to the advantages of Karlsson’s lamp-located sensor, nothing about that arrangement would have changed in the proposed combination. As described, Petitioner proposes using aspects of Nakamura’s processing in combination with Karlsson’s physical system. See Pet. 54–58. Thus, the combination preserves any advantages Karlsson obtains by locating a sensor with each illumination system. As to a change of perspective, the record does not support that Nakamura’s processing relies on a single, unchangeable perspective. Rather, Nakamura discloses identifying relevant image regions through reference markers such as “white lines of the lane” and adjustments such as “correction amount α” to accommodate the reference markers. Ex. 1013 ¶¶ 36–46; see Pet. Reply 58 (“Nakamura explains how to implement the coordinate mapping of the pixels received by a camera.”). Thus, Nakamura’s approach is already suitable to a changed perspective and Petitioner did not have to explain further details of the required adaption. See also Ex. 1052 ¶¶ 125 (“Wherever the camera is located on the vehicle, a simple calibration for camera location versus driver’s viewpoint would be conducted to carry on the image processing.”), 168 (noting that the same reasoning applies to the Karlsson–Nakamura combination as the Beam–Satonaka combination). Additionally, Patent Owner has not persuasively supported its assertion that the changed perspective—locating sensors at the headlamps rather than centered at the top of the windshield—would impair the system’s ability to detect other vehicles. See PO Resp. 57–59.

Accordingly, even viewing Patent Owner’s evidence as credible and appropriate, we conclude that it would not establish the required nexus for claim 40. To be clear, Patent Owner’s asserted evidence would not establish nexus for any aspect of the independent claims, because each element is found in the prior art and the only elements for which Petitioner asserts a combination of prior-art teachings—those relating to image coordinates—are not those that Patent Owner relies on for a unique characteristic of the claimed invention. Patent Owner asserts further that industry praise was directed at the “Predictive Curve Illumination feature” recited by dependent claims that require the ability to “accommodate the upcoming road curvature” by adapting the light. PO Resp. 8, 70–71. Patent Owner relies on a report of a new lighting system used by BMW that states, “[t]he benefit of a glare-free function is not only to shadow out other cars but also to provide visibility for upcoming curves and dangerous situations; there is a clear safety gain by illuminating this curve in front of the driver.” Ex. 2023, 727 (quoting Ex. 2023, 177) (emphasis omitted).

Accordingly, Patent Owner has not established a nexus with the dependent claims. That the praised characteristics were found in the prior art is consistent with Patent Owner’s asserted evidence, which largely pertains to efforts to change U.S. regulations to permit the use of adaptive headlight technology.

    “As to the advantages of Karlsson’s lamp-located sensor, nothing about that arrangement would have changed in the proposed combination. As described, Petitioner proposes using aspects of Nakamura’s processing in combination with Karlsson’s physical system. See Pet. 54–58. Thus, the combination preserves any advantages Karlsson obtains by locating a sensor with each illumination system. As to a change of perspective, the record does not support that Nakamura’s processing relies on a single, unchangeable perspective. Rather, Nakamura discloses identifying relevant image regions through reference markers such as “white lines of the lane” and adjustments such as “correction amount α” to accommodate the reference markers. Ex. 1013 ¶¶ 36–46; see Pet. Reply 58 (“Nakamura explains how to implement the coordinate mapping of the pixels received by a camera.”). Thus, Nakamura’s approach is already suitable to a changed perspective and Petitioner did not have to explain further details of the required adaption. See also Ex. 1052 ¶¶ 125 (“Wherever the camera is located on the vehicle, a simple calibration for camera location versus driver’s viewpoint would be conducted to carry on the image processing.”), 168 (noting that the same reasoning applies to the Karlsson–Nakamura combination as the Beam–Satonaka combination). Additionally, Patent Owner has not persuasively supported its assertion that the changed perspective—locating sensors at the headlamps rather than centered at the top of the windshield—would impair the system’s ability to detect other vehicles. See PO Resp. 57–59. Patent Owner’s expert could not testify as to the camera locations used to generate the images that form the basis for Patent Owner’s argument, as he was not present at the test that generated those images.

    “separate ‘reordering procedure,’ to which the timer is tied.” Id. (emphasis added). We agree that the cited evidence in Sachs more closely supports Petitioner’s position that the “timer is stopped when and because the missing PDUs are received,” and not after the occurrence of some additional step in which PDUs in the RLC buffer are shuffled into sequential order. Petitioner persuasively supports its position with, for example, its annotated version of Figure 5, reproduced above, which depicts that the T_reorder timer is stopped when out-of-order PDUs 3 and 4 are received––Sachs does not depict or describe an additional step of reshuffling occurring before the timer is stopped. Pet. 41. Patent Owner’s argument that Sachs teaches “a reordering procedure is performed before any other actions are taken” is unavailing because it is not supported by the cited evidence. In support of this argument, Patent Owner’s Declarant, Mr. Regis J. Bates, Jr., offers similar testimony that “the expiry of the timer in Sachs does not trigger a status report as in the ’396 patent, instead a reordering procedure is performed before any other actions are taken,” but does not explain why the reordering procedure takes place before “any other actions.” Ex. 2001 ¶ 53 (citing Ex. 1003, Figs. 4, 5, Abstract, 8:25–31, 9:11–15) (emphasis added). In his Second Declaration, Mr. Bates adds no further detail or explanation and cites the same portions of Sachs. Ex. 2006 ¶ 29.

    “copper interconnects need silicon nitride films as an etch stop, but that such films have a high dielectric constant, which causes an undesirable increase in the effective dielectric constant of the interconnect structure and increased parasitic capacitance, as compared with aluminum interconnects. Ex. 1021, 829-1, 829-2; see Pet. 18; Ex. 1011 ¶¶ 92, 93. As Petitioner correctly points out (Pet. 53–54), Tanaka (1999) cites Igarashi as an example of a copper interconnect system that is degraded by parasitic capacitance due to the high permittivity (dielectric constant) of silicon nitride etch stop films. Ex. 1017, 47-1 n.1. Tanaka (1999) discloses a low dielectric constant silicon nitride etch stop film as a solution to the problem of parasitic capacitance in copper damascene interconnect structures, such as Igarashi’s. Id. at 47-1, 47-2 (“New low-k SiN film, with a permittivity of 5.4 . . . should be the solution to realize Cu damascene interconnects . . . .”).

As discussed above and argued by Petitioner, Tanaka (1999): (1) cites Igarashi as an example of a copper interconnect system that suffers from parasitic capacitance due to the high dielectric constant of silicon nitride etch stop films, and (2) discloses a low dielectric constant silicon nitride etch stop film as a solution to the parasitic capacitance problem exemplified by Igarashi. Pet. 13, 18, 53–54; Ex. 1011 ¶¶ 74–79, 88–94; Ex. 1017, 47-1 & n.1; Ex. 1021, 829-1, 829-2. Petitioner establishes a reasonable expectation of success for the combination of Tanaka (1999) and Igarashi by demonstrating a strong correlation between the problem discussed by Igarashi—the high dielectric constant of silicon nitride films when used as etch stops for copper interconnects—and the solution disclosed by Tanaka (1999)—a low dielectric constant silicon nitride film for use as an etch stop layer in copper damascene interconnect structures. In re Inland Steel Co., 265 F.3d 1354, 1364 (Fed. Cir. 2001) (“[T]he strength of the correlation between the references gives rise to a reasonable expectation of success from combining them.”).” slip op. at 27

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “(“POSITA”) at the time of the ’774 patent would have had “a bachelor’s degree in materials science, electrical engineering, mechanical engineering, chemistry, or a closely related field, and at least five years of experience” in industry or academic research relating to magnetic tape, or “a master’s degree or higher” in the same fields and at least three years of experience relating to magnetic tape. Pet. 13 (citing Ex. 1003 ¶ 65; Ex. 1018 ¶ 60). Patent Owner does not dispute Petitioner’s assessment in its Response, and Dr. Talke agrees that it “is reasonable.” Ex. 2026 ¶¶ 25–26. Petitioner’s assessment appears consistent with the level of ordinary skill in the art at the time of the invention as reflected in the prior art in this proceeding. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163–64 (Fed. Cir. 1985))). Accordingly, we adopt Petitioner’s assessment of the level of ordinary skill in the art.” slip op. at 8

    “the broadest reasonable construction, claim terms are presumed to have their ordinary and customary meaning as understood by a person of ordinary skill in the art in the context of the entire patent disclosure. In re Translogic Tech., Inc., 504 F.3d 1249, 1257 (Fed. Cir. 2007). Only those terms in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). For the purposes of the Decision on Institution, we determined that, based on the record at that time, no claim term required express construction (Dec. on Inst. 7), and we see no reason to modify that determination in light of the record developed during trial.

    “considerably greater than Ishikawa’s stylus load of 50–300 μN (Ex. 1015 ¶ 45). The Talke Declaration does not address this discrepancy, and Dr. Talke stated during his deposition that reducing the stylus load would reduce scratching of the magnetic tape surface. Ex. 1030, 108:14–19 (“Q: Would reducing the contact pressure for the stylus instrument reduce the scratching of the magnetic tape surface by the stylus? A: Yes, it would, but you have to remember the other problem is the diameter and size of the stylus.”). Moreover, Petitioner provides evidence that it was not uncommon to use stylus-type profilometers to measure the properties of magnetic tape, even after Bhushan was published in 1996. See Reply 6. In particular, Petitioner points to Saliba,6 which describes using a stylus-type profilometer, under identical conditions to those used in Ishikawa, to measure the surface characteristics (including peak-to-valley roughness) of the backcoating of magnetic tape. Ex. 1027, 7:28–40, 57–60. Petitioner further points to Ohno,7 which also describes using “a stylus type 3D profilometer in accordance with JIS B0601” to measure the surface roughness characteristics of magnetic tape. Ex. 1028 ¶ 36; see also Ex. 1015 ¶ 45 (Ishikawa explaining that surface roughness characteristics were measured “in accordance with JIS-B0601-1994”); Ex. 1027, 7:28–39 (Saliba explaining that surface roughness characteristics where measured “in accordance with JIS-B0601-1994”). Accordingly, we are persuaded that the 6 US Patent No. 6,558,774 B1, issued May 6, 2003 (Ex. 1027). 7 U.S. Patent App. Pub. No. US 2005/0175866 A1, published Aug. 11, 2005 (Ex. 1028). evidence establishes that a stylus-type profilometer is a suitable device for measuring the surface characteristics of magnetic tape.” slip op. at 19

    “We agree with Petitioner that Ishikawa teaches “peak-to-valley roughness less than about 325 nm” as recited in claim 15. Pet. 24–25; Reply 5–8; Ex. 1003 ¶ 216. In particular, Ishikawa teaches a backcoating layer of a magnetic tape that has a peak-to-valley roughness “Rz of 40 to 250 nm, particularly 50 to 200 nm.” Ex. 1015 ¶ 44. Ishikawa provides five example embodiments of its magnetic tape, and reports the measurements of a number of characteristics of the backcoat layer for each example, including peak-to-valley roughness Rz. Id. ¶¶ 120–134, Table 1. Ishikawa discloses that peak-to-valley roughness Rz was measured using a stylus-type profilometer under the following conditions: Stylus: diameter: 1.5 to 2.5 μm; curvature: 60º Contact pressure: 50 to 300 μN Cut-off length: 80 μm Sampling length: 80 μm Assessment length: 400 μm Id. ¶¶ 45, 49. The reported peak-to-valley roughness Rz values for the five examples ranged from 58 to 87 nm, as shown in the annotated portion of Ishikawa Table 1 from the Petition, reproduced below: Pet. 24 (citing Ex. 1015, Table 1). The annotated portion of Ishikawa Table 1 shows the results for the measured characteristics of the backcoat layer of Examples 1–5, with the peak-to-valley roughness Rz values highlighted by a red box. Id. Because Ishikawa teaches that the backcoating layer of its magnetic tape should have a peak-to-valley roughness “Rz of 40 to 250 nm, particularly 50 to 200 nm,” and because Ishikawa presents examples of magnetic tape with backside surfaces having a peak-to-valley roughness of 87 nm or less, Ishikawa discloses “a peak-to-valley roughness less than about 325 nm” as recited in claim 15.” slip op. at 16
