“We agree with Patent Owner that Petitioner has failed to provide adequate evidence and analysis to show that Kelly discloses storing the identified user input in Kelly’s system. For instance, the portion of Kelly relied upon in the Petition describes how user input provides a particular game command to game processor 12, and game processor 12 interprets and uses this input to influence game states and game events. Ex. 1005, 10:12– 15. The portion of Kelly makes no mention of storing the user input. Petitioner also cites generally to other portions of Kelly with insufficient explanation of their relevance. Pet. 22; Ex. 1003 ¶ 136 (citing 1:44–46, 9:62–66, 46:32–37, 46:49–52).

“For purposes of our analysis, we need only address the meaning of “planar structure,” and only to note that this limitation requires that all portions of the casing body, when inflated against the first mesh portion, second mesh portion, and tie elements, “form a planar structure” when the casing body is inflated. This is evident from both the claim language and the written description of the ’065 patent. Limitation [1e] of claim 1 recites that in the inflated condition, “said portions of the casing body” are “inflated against said first mesh portion, said second mesh portion, and said tie elements.” We understand “said portions of the casing body” to refer to all of the portions of the casing body. Likewise, “said first mesh portion, said second mesh portion, and said tie elements” refers to the entire mesh structure recited in limitation [1a]. Thus, this limitation requires all of the casing-body portions to inflate against the entire mesh structure to form the “planar structure.” This reading is consistent with the Specification. The Specification teaches that “[t]he first mesh portion and the second mesh portion together with the tie elements determine with the casing body the final shape of the inflatable element,” which “can reach a generally flat and planar final shape.” Ex. 1001, 4:19–23; see also id. at 4:59–5:3 (teaching that the casing body inflated within the mesh structure results in a “globally planar structure”).

Petitioner also asserts that the proposed level of skill would be the same under any of the United States, Japanese, or PCT application dates. Id. at 8–9 (citing Ex. 1024 ¶¶ 24–25). Patent Owner does not challenge Petitioner’s proposed level of qualifications for one of ordinary skill in the art. Prelim. Resp. 20.

“As discussed above, Petitioner relies upon Parkin, and its layers 115 and 175, as the claimed first and second ferromagnetic material layers, respectively. See Pet. 10, 16. Petitioner admits that these layers are 8 In the Petition, Petitioner refers to the lower electrode “ferromagnetic layer 110’ as discussed in Claim 1[a]” in the discussion of limitation 1[d]. Pet. 18. Petitioner’s reference to “layer 110’” appears to be in error because the Petition’s discussion for limitation 1[a] refers to layer 115 of Parkin, as does Dr. Bokor’s testimony related to limitations 1[a] and 1[d]. Pet. 10; Ex. 1024 ¶¶ 109, 136. amorphous, but contends that, as Parkin discloses, these layers may be annealed. Id. at 17. Petitioner, however, refers to Parkin’s disclosure that only “a portion of the storage layer 175” is crystallized after annealing. Id. at 17–18 (citing Ex. 1062, 18:51–55) (emphasis added). Petitioner also relies upon Parkin’s “thin crystalline ferromagnetic layer” that is crystallized to teach limitation 1[d]. Id. at 18 (citing Ex. 1062, 18:55–59; Ex. 1024 ¶¶ 131–132) (emphasis added). Dr. Bokor additionally testifies that it is “Parkin’s ‘thin crystalline ferromagnetic layer’ of CoFeB” that meets the “entirely crystallized” requirement of limitation 1[d]. Ex. 1024 ¶ 132. Parkin, however, states that a thin crystalline ferromagnetic layer is formed, but “the bulk of storage layer 175 remains amorphous.” Ex. 1062, 18:55–60 (emphasis added). Petitioner fails to reconcile how its assertions that the first and second ferromagnetic layers, which are mapped to the totality of layers of 115 and 175, meet the limitation that the first and second ferromagnetic layers are each “entirely crystallized” when Petitioner relies only a thin layer, that is, a portion, of the 115 and 175 layers for the teaching that the respective layers are entirely crystallized. Put another way, Petitioner’s mapping is inconsistent: Petitioner relies upon the full depth of certain “layers” of Parkin for the teaching of the ferromagnetic layers, but then only relies upon thin portion of that depth for the assertion that the “layers” are entirely crystallized.” slip op. at 16

“distinguishes and contrasts build material property from operational parameters. The diagnostic test passage therefore only describes a diagnostic test of the build material property but does not describe a subsequent diagnostic test to assess whether an operational parameter is suitable for the printer. Based solely on the diagnostic test passage and the prosecution history, a possible interpretation may be that the operational parameter determination in claim element 1b encompasses the diagnostic testing in claim element 1c. That is, “performing a diagnostic test to determine whether the operational parameter is suitable for the three-dimensional printer” in claim element 1c is subsumed as part of “determining an operational parameter of a fabrication process using the three-dimensional printer based upon the data, the operational parameter including at least one of a build platform temperature, a build volume temperature, an infill requirement, a rafting requirement, a support structure requirement, and a cooling requirement” in claim element 1b.” slip op. at 15

Petitioner also contends that “[a]dditional experience could substitute for a formal degree or formal training (and vice versa).” Id. (citing the same). Patent Owner contends that an ordinarily skilled artisan “would have had a bachelor’s degree in Mechanical Engineering, Computer Engineering, Electrical Engineering, Chemical Engineering, Materials Science, or a comparable field and at least two years of experience related to 3D printing, with additional experience potentially being a substitute for a formal degree or training (and vice versa).” Prelim.
