    “Exhibits 1013 and 1014 are also not admissible as expert testimony because Mr. Wirén is not “qualified as an expert by knowledge, skill, experience, training, or education.” Fed. R. Evid. 703. “To offer expert testimony from the perspective of a skilled artisan in a patent case—like for claim construction, validity, or infringement—a witness must at least have ordinary skill in the art. Without that skill, the witness’ opinions are neither relevant nor reliable.” Kyocera Senco Indus. Tools Inc. v. Int’l Trade Comm’n, 22 F.4th 1369, 1376–77 (Fed. Cir. 2022).

    “a contact surface of said thermo-roller is heated to an elevated temperature of at least 250°F.” Petitioner shows persuasively that the temperature limitation is taught by the combination of Fugitt and Papermaking. Pet. 32–34. Fugitt discloses that “[t]he rolls of the calender may be steam heated.” Ex. 1004 ¶ 26. In a section titled “Heated Rolls,” Papermaking discloses that “Steam can be used up to 170°C [338°F] surface temperature.” Ex. 1010, 95, 98. Petitioner is thus correct that, “[w]hile Fugitt teaches that a hot calender may be steam heated, Papermaking clarifies that one of ordinary skill in the art would understand that steam heated thermo-rollers may reach up to 338°F.” Pet. 36. Based on these disclosures, we are persuaded by Mr. Zotterman’s testimony that it would have been “obvious to heat the thermo-roller of Fugitt to at least 250°F.” Ex. 1003 ¶ 159. combine Fugitt and Papermaking because of Papermaking’s status as a “trusted handbook[],” because both references disclose a method of manufacturing a paperboard structure with hot calendering,” and “because of the known advantages of heated rollers.” Pet. 36–37; Ex. 1003 ¶¶ 157, 159, 162. Petitioner’s contention is supported by Papermaking’s disclosures that, for cartonboard, “[p]recalendering is used before the coater to reduce roughness and porosity” and “[h]igh thermo roll temperatures (in some cases over 200°C) result in bulk savings because of the temperature gradient.” Ex. 1005, 80–82; see also Pet. 38; Ex. 1003 ¶ 164 (citing these disclosures). Papermaking’s disclosed range of “up to 170°C [338°F]” for steam- heated rolls (Ex. 1010, 98), overlaps the claimed range of “at least 250°F.” Patent Owner agrees. Tr. 27:11–13. “If the relevant comparison between a disputed claim limitation and the prior art pertains to a range of overlapping values, ‘. . . even a slight overlap in range establishes a prima facie case of obviousness.’” Genentech, Inc. v.

Contrary to Patent Owner’s arguments, Sakamoto provides no general teaching against using a charge cut-off voltage above 4.2 V, or against increasing the level of lithium in circulation.

    “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.

    “the structure and function of the 2006 904 Operating Manual’s product holder and Lindee’s grippers are similar in that they serve to grip food product and guide it to the slicing station. See, e.g., Ex. 1005, 23; Ex. 1006, 18:20–35, Fig. 7A. The two devices differ in their actuation—the 2006 904 Operating Manual uses a ball screw spindle actuator to drive the product holder along the feed path, whereas Lindee uses a timing belt 334 to drive its grippers 151 along the feed path. Ex. 1005, 273–274; Ex. 1006, 18:33–34, Fig. 7A. However, Petitioner presented evidence that “unlike ball screws, belt drives do not require periodic lubrication with grease or exhibit backlash when they change direction.” Ex. 1003 ¶ 160. In addition, Petitioner demonstrates that a POSA at the time would have understood that conveyor belts like Lindee’s can be easily cleaned. Ex. 1051 ¶¶ 50–54. Petitioner further asserted that conveyor belts are easy to maintain at low cost. Id. citing ¶¶ 55–58. We agree with Petitioner that, at least for some scenarios, including those that Petitioner specifies, a POSA would have seen that there were advantages to using Lindee’s timing belt rather than the 2006 904 Operating Manual’s ball-screw to drive food article grippers. Petitioner has demonstrated a POSA would have been motivated to combine Lindee’s belt-driven grippers in the 2006 904 Operating Manual’s food slicer notwithstanding Patent Owner’s arguments to the contrary.” slip op. at 50

    “In determining the level of ordinary skill in the art, various factors may be considered, including the “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 Inc., 57 F.3d 1573, 1579 (Fed.

Neither party argues that the outcome of this case would differ based on our adoption of any particular definition of the level of ordinary skill in the art. Considering the subject matter of the ’256 patent, the background technical field, the prior art, and Petitioner’s unopposed definition of the skilled artisan, we apply the level of skill set forth above, which is consistent with the testimony of Dr. Lynch (Ex. 1003 ¶¶ 43, 44).” slip op. at 13

Patent Owner does not contest the prior art status of Arrasvuori. Also, on this record, we have no evidence of an invention date other than the earliest possible effective filing date of the challenged claims. Thus, for purposes of this Decision, we determine that Arrasvuori qualifies as prior art under 35 U.S.C. § 102(a) because Arrasvuori’s publication date of October 11, 2007, is before the earliest possible effective filing date of the challenged claims, which is March 3, 2008, and under § 102(e) because Arrasvuori’s filing date of March 29, 2006, is before the earliest possible effective filing date of the challenged claims (March 3, 2008).

We find that these descriptions in Arrasvuori provide an anticipatory disclosure, particularly to the skilled artisan, of the limitation “wirelessly-connected sensor worn on an appendage of a first user.” See Ex. 1017 ¶ 45; Ex. 2006, 84:10-85:22. Although Arrasvuori does not recite in a single sentence the substance of disclosures (a) through (d) above, such as explicitly stating that its “wireless node is a computerized watch,” this is not necessary for the skilled artisan to understand that Arrasvuori discloses such a feature. See In re Bond, 910 F.2d at 832–33 (anticipation “is not an ‘ipsissimis verbis’ test”). Moreover, as argued by Petitioner, Arrasvuori’s disclosure of sensors “attached to bodies of users” and of users “wear[ing]” sensors itself discloses the subject limitation as broadly recited, even without considering the additional disclosure of a computerized watch.

Petitioner’s objection to Dr. Baura’s testimony identifies hundreds of paragraphs from her declaration followed by an objection stating her “testimony is based on insufficient facts or data, is not the product of reliable principles and methods, and does not reliably apply the appropriate principles and methods to the fact of the case.” Paper 25, 2. Petitioner’s boilerplate objection is woefully insufficient to show that Petitioner objected with sufficiently particularity to allow correction in the form of supplemental information, as our Rule requires.

Petitioner directs us to no evidence in Heller expressly addressing a predictive relationship between in vitro and in vivo sensitivity, much less any disclosure in Heller of a particular relationship. Instead, Petitioner seeks to stretch a thin disclosure in Heller that “calibration data may simply be factory-determined calibration measurements” to necessarily mean “prior sensitivity information is derived at least in part from a predictive relationship between an in vitro sensor sensitivity to glucose and an in vivo sensor sensitivity to glucose,” as required by claim 23.

From Heller’s disclosure preponderance of the evidence that Heller expressly teaches any predictive relationship, even one in which in vitro and in vivo sensitivity are the same. that calibration data can “simply be factory determined calibration measurements,” Petitioner provides no more than speculation to suggest that there necessarily must be some relationship between in vitro measurements and in vivo measurements.

Cir. 2022) (“We have repeatedly held that ‘it is not enough that the only embodiments, or all of the embodiments, contain a particular limitation to limit claims beyond their plain meaning.’”) (citation omitted). And, regardless of the exact wording, the concern we have is that without a persuasive, express, indication in the specification that the “second function” is specifically limited to “predicting glucose values,” it is a disfavored path to read limitations into the claims. Though understanding the claim language may be aided by the explanations contained in the written description, it is important not to import limitations into a claim that are not expressly part of may not be read into a claim when the claim language is broader than the embodiment.
