Id. at 14–15. In particular, we were not persuaded that “Seo creates a large lateral electric field like the one described in Choi,” and, in any case, we disagreed that “Choi teaches that a large lateral electric field removes fast charges.” Id. at 15. Accordingly, regardless of the duration of the voltage application described in Seo, Petitioner failed to show that the combination of Seo and Choi would result in removal of fast charges.

“the knowledge of one of ordinary skill in the art relating to charge-trap memory devices demonstrates fast charge removal. See Pet. 36, 81–82. And although Petitioner cites its declarant, Dr. Liu, for the proposition that “Seo discloses, and would have been understood to disclose, performing its read operation on charge-trap memories, which removes fast charges,” Dr. Liu does not cite objective evidence to support this assertion, aside from the ’342 patent itself. Id. at 36 (citing Ex. 1003 ¶ 136). Moreover, Dr. Liu’s testimony simply circles back to logic similar to that relied on with respect to the inherency theory, namely that, given certain similarities between Seo and the ’342 patent, Seo removes fast charges because the ’342 patent teaches removing fast charges, even though Seo does not explicitly teach doing so. See Ex. 1003 ¶ 136 (“[A] POSITA would have immediately understood from reading Seo that Seo is disclosing its read operation as applicable to Flash memories, including Flash charge-trap memories. And as the ’342 states, Seo’s operation would remove fast charges in a charge-trap memory.” (citing Ex. 1001, Abstract)). As already discussed, we disagree with this logic based on the lack of sufficient evidence to support its conclusion. See Dec. 13 (“Petitioner and Dr. Liu do not provide any objective evidence or explanation as to how or why a POSITA would have understood that Seo’s voltage amounts applied during Seo’s time periods operate the same way [as in the ’342 patent] on Seo’s memory device to generate fields with sufficient magnitude and duration to remove fast charges.”). Petitioner’s assertions regarding Nam suffer from the same shortcomings.

“Here, the pull-tab does serve a useful purpose as it can be used to pull the footwear onto the foot. Based on the evidence presented, however, we disagree with Petitioner that the pull tab is primarily functional and should be removed entirely from the construction of the claimed design. Petitioner presents a number of arguments to support its position that the pull tab is functional, not ornamental. Petitioner asserts that the pull tab is “obviously not ornamentation but instead is a functional element that is used to pull the footwear on to the foot, an important function and part of the Patent Owner’s marketing message.” Pet. 18–19 (citing Ex. 1011 ¶¶ 64–67; possible, the type of pull tab shown in the ’161 patent “is the kind that is generally used in shorter shaft, lower ankle height footwear to make it easier to pull up and put the boot on the foot.” Pet. 19 (citing Ex. 1009, the UGG Neumel Boot). Petitioner further asserts that the pull tab is “securely attached for actual use, countering that it is ornamental” and that “[a]ny other pull tab (e.g., not at the top of the footwear as in the UGG Neumel Boot) would not be as efficient and hence not an acceptable alternative.” Id. (citing Ex. 1011 ¶¶ 64–67; Ex. 1013, 25–27). We are not persuaded by these arguments. The “marketing material” relied on by Petition, as discussed by Mr. Holden, merely states that Ultra Mini Ugg Boots “have a slightly lower ankle to make it easier for you to slip on,” that the UGG boots are “fantastic” for those who “may struggle with pulling on other styles,” and the boots “are fantastic for those who may struggle with pulling on other styles and are looking for more comfort and durability.” See Ex. 1011 ¶ 66 (citing Ex. 1003).

“Petitioner’s arguments are not persuasive. First, the images of the Emu Stinger Micro Boot that Petitioner relies upon are from pages 1–6 of Exhibit 1002, which as noted above, Petitioner has not sufficiently shown to constitute a printed publication prior art. Thus, Petitioner’s arguments are based on images in a reference that does not qualify as prior art to the claimed design. The images found on pages 8 and 9 of Exhibit 1002 are not the same images as those relied upon in the Petition. Compare Ex. 1002, 8– 9, with Pet. 35–36. Thus, for at least this reason, Petitioner fails to demonstrate a reasonable likelihood that it would prevail in showing the ’161 patent is anticipated by the Emu Stinger Boot. Second, even if we were to consider any of these images of the Emu Stinger Micro Boot depicted in Exhibit 1002, Petitioner’s arguments are not persuasive because the arguments fail to adequately address differences between the claimed design and the prior art as viewed by an ordinary observer. See Door-Master Corp., 256 F.3d at 1313 (stating for anticipation to be found, the claimed design and the prior art design must be substantially the same). For example, the Figures of the ’161 patent depict (1) a stitch pattern design that includes a wavy line on the back heel of the boot (see Figs. 1–3, 5), (2) a pull tab that extends over the top part of the back of the boot and opening for insertion of the foot that appears to constitute more than 50% of the length of the boot (Figs. 2, 3, 6), and (4) a backward sloping top line.

“Petitioner’s position is unpersuasive. It is not evident from the record that the skilled artisan would have understood that a window equates to a hole or “air inlet passage” as claimed. Indeed, the record suggests otherwise. For example, Verleur explains that: The shell may include a window provided at the cartomizer receiving segment so that a portion of the chamber is visible from outside the shell. [Ex. 1005 ¶ 27]. One or more windows 130 may be provided in outer shell 106 (see FIG. 1). Windows 130 may be made of a translucent material, such as glass or substantially clear plastic, in order to view internal components of battery portion 100. [Id. ¶ 37] For instance, in one embodiment, window 130 may be provided on or proximate to cartomizer receiving segment 104 and, more particularly, cartomizer chamber 108 so as to permit a user of electronic cigarette 10 to view the cartomizer 200 when it is inserted into cartomizer chamber 108. [Id.]. At least a portion of body 208 may be composed of translucent or substantially translucent material, such as glass or plastic, so that a user may see fluid 300A held within. The portion of body 208 composed of translucent material may be alignable with window 130 . . . . [Id. ¶ 38]. Petitioner itself acknowledges that window 130 of Verleur “may be made of a translucent material, such as glass or substantially clear plastic” and that the purpose of window 130 is “to view internal components of battery portion 100.” Pet. 29 (quoting Ex. 1005 ¶ 37). Thus, Verleur provides that window 130 may be translucent to allow a user to view internal components, and Verleur makes no mention that window 130 is a hole or slit that allows air to enter. Ex. 1005 ¶¶ 37–38. Neither Petitioner nor its declarant Dr. Singhose adequately explains why the ordinarily skilled artisan would have understood window 130 to be an air inlet passage that allows air to enter gap “formed by an exterior surface of the cartridge and . . . an internal surface of the receptacle.” In contrast, Patent Owner, through the testimony of Dr. Collins, persuasively explains that the skilled artisan would have understood that Verleur’s window 130 is not an air inlet passage. Ex. 2001 ¶¶ 48–49; Prelim. Resp. 11–13. Dr. Collins explains that “[w]indow 130 is a window . . . ‘to view internal components of battery portion 100,’ such as ‘to permit a user . . . to view the cartomizer 200 when it is inserted into cartomizer chamber 108.’” Ex. 2001 ¶¶ 46–47 (third alteration in original). Dr. Collins further testifies that “Verleur knew how to describe an air inlet on the outside of the shell, since one is described in a different embodiment.” Id. ¶ 45. Alternatively, Petitioner contends that “to the extent window 130 is not a slit, but instead comprises glass or plastic, a hole would nonetheless be needed elsewhere in the shell to permit air into the gap between the cartomizer 200/200A and the outer shell 106.” Pet. 34. Petitioner points to Verleur paragraph 39, which describes holes or ducts in the outer shell. Id. However, where Verleur describes the existence of holes or ducts for air flow, the air flow is described as flowing though the cartomizer body itself and not through the gap or channel formed where the cartomizer is inserted into the shell chamber. Ex. 1005 ¶ 39 (stating that “[i]nhalation tube 222 may also be in fluid communication with one or more holes or ducts provided, for instance, in sides of outer shell 106 in order to permit air flow through cartomizer body 208” (emphasis added)). This is consistent with Dr. Collins’s testimony that “[s]uch a mechanism would allow air to flow directly into the cartomizer through aligned holes.” Ex. 2001 ¶ 66 (emphasis added).
