“persuasive for several reasons. The claim does not recite “a defined physical playfield.” Rather, the claim recites “a physical playfield.” The Specification’s discussions of “playfield” cited by Patent Owner use non-limiting language such as “for example” and “may” in describing the playfield. Ex. 1001, 2:32–36, 2:55–61, 3:14–16, 5:63–65, 6:30–32, 8:31–45, 9:4–9, 19:60–20:22, 22:5–6. The disclosed examples of “a physical playfield” include “the physical world, a physical environment, or a defined physical playfield” (Ex. 1001, 1:56–58), which indicates that the applicant intended “a physical playfield” as claimed to encompass more than a defined or “bounded” physical playfield. This indication is consistent with the Specification’s disclosure that “the game world corresponds to an actual area of the physical world (such as the planet Earth or New York City).” Ex. 1001, 11:12–14. Thus, in one disclosed embodiment, the physical playfield is the entire (unbounded) world. We are persuaded that the Specification’s descriptions of various embodiments with defined playfields and undefined playfields support construing the scope of a “physical playfield” as encompassing defined boundaries, or a “bounded” playfield, as well as a “physical playfield” with undefined boundaries, or an “unbounded” playfield. Limiting the claim term to only “bounded” play spaces would read out broader embodiments from the claim scope. Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1583 (Fed.

“A reference qualifies as prior art for an obviousness determination under § 103 only when it is analogous to the claimed invention. Two separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved. . . . A reference is reasonably pertinent if, even though it may be in a different field from that of the inventor’s endeavor, it is one which, because of the matter with which it deals, logically would have commended itself to an inventor’s attention in considering his problem. If a reference disclosure has the same purpose as the claimed invention, the reference relates to the same problem, and that fact supports use of that reference in an obviousness rejection. In re Klein, 647 F.3d 1343, 1348 (Fed. Cir. 2011). Jaszlics discloses that the “invention relates . . . to systems for combining virtual images with real-world scenes” to provide applications such as virtual reality games (Ex. 1003, 1:13–21), which is the same field as the ’448 patent’s field of “location-based games and augmented reality systems” (Ex. 1001, Title). Turning to Sofer, the purpose of the detector of Sofer is to detect the location of objects in the user’s surrounding environment (Ex. 1008, Abstract; see id. at 2, 6, 11), which is the same purpose as the detector of the ’448 patent (Ex. 1001, 15:4–5; see id. at 1:28–31, 2:5, 16:11–18, 19:54–57). Therefore, Sofer’s detector is reasonably pertinent to the particular problem of detecting the location of objects in the user’s surrounding environment. We are sufficiently persuaded that Jaszlics and Sofer are analogous to the claimed invention.” slip op. at 14

Petitioner’s arguments and evidence regarding motivation to combine amount to showing that “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR Int’l Co. v.

“A reference that is in the same field of endeavor as the claimed invention is analogous art,5 and such a qualification means that one of ordinary skill in the art is presumed to have been aware of the reference and thus the refence properly may be considered if it predates the claimed invention. See Circuit Check Inc. v. QXQ Inc., 795 F.3d 1331, 1335 (Fed. Cir. 2015). Petitioner contends that the field of endeavor of the claims of the ’243 patent is “the field of portable user-worn devices for providing location based-entertainment.” Pet. 19−20. According to that description of the relevant field of endeavor, Petitioner argues that both Levesque and Ronzani are analogous to the ’243 patent. Id. Patent Owner appears to argue that the field of endeavor is “video games.” Prelim. Resp. 29−30. This is not the correct field of endeavor because although the claim recites a location based game system, the claims considerably focus on the head-mounted device. Indeed, for claim 1 all the structural elements claimed involve or are placed in the head-mounted device. Thus, “video games” generally is not an appropriate field of endeavor, as it is too broad and ignores the significant focus of the claims of the ’243 patent. Petitioner’s statement of the field of endeavor is, therefore, more indicative of the correct field of endeavor involved here. And as such, it is unpersuasive to argue that Ronzani does not belong to the field merely because it is not solely focused on video” slip op. at 18

In an IPR, we construe a patent claim “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b).” 37 C.F.R. § 42.100(b). This generally includes “construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” Id. The ordinary and customary meaning of a claim term “is its meaning to the ordinary artisan after reading the entire patent,” and “as of the effective filing date of the patent application.” Phillips, 415 F.3d at 1313, 1321. Neither Petitioner nor Patent Owner argues that we need to construe any claim terms explicitly. See Pet. 2–3; Prelim. Resp. 9. However, the parties’ positions depend on interpreting the claim language in a particular way, and we discuss the relevant claim language below in the context of the parties’ arguments regarding the prior art. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

“At this stage, we find Petitioner’s arguments persuasive and disagree with Patent Owner. Patent Owner appears to equate a “fabrication profile” with a toolpath description, but nothing in the plain language of claim 1 supports that narrow interpretation. The ’774 patent describes a “fabrication profile” broadly and states that the profile can simply “include the dictionary [of configuration information],” or be “used to determine which machineready representation is available or suitable for a target printer.” Ex. 1001, 23:49–52. The preliminary evidence suggests that Douglas’s “operational parameters” would count as a “fabrication profile” because it is “the basis for generation of a machine-ready representation of the three-dimensional model that is executable on the target printer.” Id. at 23:37–39; see infra Section III.C.8. We also disagree that Petitioner’s argument is impermissible hindsight, because it is based on the disclosures in Douglas and Mark, and Petitioner has articulated a sufficiently persuasive reason to combine those references without referring to the ’774 patent itself. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (an obvious rationale is not improper hindsight if it “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”). Finally, Petitioner appears to rely on Mark for providing a particular example of a fabrication profile, not to replace Douglas’s overall system in which the 3D printer can receive “operational parameters” rather than just G-code. See Pet. 8–10, 17–23; see also Ex. 1005 ¶ 41 (the print queue, which stores tool instructions, may be maintained locally on printers 204 or on print servers 208); see In re Mouttet, 686 F.3d 1322, 1332 (Fed.

The claim does not recite “a defined physical playfield.” Rather, the claim recites “a physical playfield.” The Paper 10 in the 740 IPR; and Patent Owner filed a Preliminary Sur-reply, filed as Paper 11 in the 740 IPR.

“persuasive for several reasons. The claim does not recite “a defined physical playfield.” Rather, the claim recites “a physical playfield.” Ex. 1001, 21:6– 7; 22:26–27. The Specification’s discussions of “playfield” cited by Patent Owner use non-limiting language such as “for example” and “may” in describing the playfield. Id. at 2:32–36, 2:55–61, 3:14–16, 5:63–65, 6:30– 32, 8:30–44, 9:4–9, 19:60–20:22, 22:5–6. The disclosed examples of “a physical playfield” include “the physical world, a physical environment, or a defined physical playfield” (Ex. 1001, 1:51–53), which indicates that applicant intended “a physical playfield” as claimed to encompass more than a defined, or “bounded” physical playfield. This indication is consistent with the Specification’s disclosure that “the game world corresponds to an actual area of the physical world (such as the planet Earth or New York City).” Ex. 1001, 10:58–61. Thus, in one disclosed embodiment, the physical playfield is the entire (unbounded) world. We are persuaded that the Specification’s descriptions of various embodiments with defined playfields and undefined playfields support construing the scope of a “physical playfield” as encompassing defined boundaries, or a “bounded” playfield, as well as a “physical playfield” with undefined boundaries, or an “unbounded” playfield. Limiting the claim term to only “bounded” play spaces would read out broader embodiments from the claim scope. Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1583 (Fed. Cir. 1996) (holding that interpreting a claim to exclude an embodiment disclosed in the written description “is rarely, if ever, correct and would require highly persuasive evidentiary support, which is wholly absent in this case.”). We, therefore, agree at this juncture with Petitioner’s claim construction analysis, and note that the alleged goal of improving the safety in virtual reality gaming does not support Patent Owner’s construction. Paper 10, 2 (Petitioner arguing that by describing an augmented reality system where a user can view the physical surroundings, a “bounded” physical playfield is not necessary). Further, we find unpersuasive, at this juncture, Patent Owner’s arguments related to embodiments of how the information about the playfield is captured and stored to construct the playfield and perform scaling. Prelim. Resp. 7−13. As Petitioner notes, and we agree, none of these features are recited in the independent claims. Paper 10, 2. And, to the extent there is a distinction between being “on” or “off” the “physical playfield” as Patent Owner argues, the claim language requires no such determination or detection.” slip op. at 6

“physical playfield” as properly construed. Prelim. Resp. 30. As discussed in our claim construction above, we are not persuaded that the claim term “physical playfield” is limited to a bounded physical play space. However, even under the Patent Owner’s proposed narrower construction, we are sufficiently persuaded that the combination teaches a bounded physical play space. Jaszlics discloses that its system creates virtual elements in theme parks and entertainment-oriented environments. Ex. 1003, 2:14–16, 2:67– 3:1; see id. at 18:48–55. We are sufficiently persuaded that a theme park is a bounded physical play space. In addition, Jaszlics discloses training armored vehicle crews by using both virtual vehicles and actual vehicles moving over real terrain. Ex. 1003, 1:38–60. We are sufficiently persuaded that a skilled artisan would have envisioned that such training occurs on a military base, which is bounded.8 Jaszlics further discloses that its training field includes boundary markers. Ex. 1003, Fig. 15, 10:1–9. We are sufficiently persuaded that the tank training field of Jaszlics, which has boundary markers and is located on a military base, is a bounded physical play space. Therefore, even under Patent Owner’s narrower construction, we are sufficiently persuaded that a person of ordinary skill would have recognized that a user would have played at least some of the video games provided by the combined system of Jaszlics and Piekarski in a bounded physical play space such as a theme park or a military base. slip op. at 9

“institute an inter partes review. The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted unless “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” The Supreme Court has held that the Board, in a decision to institute under 35 U.S.C. § 314(b), may not institute review on less than all claims challenged in the petition.

“We disagree with Patent Owner’s contentions that these disclosures indicate that Wilson’s patch would not meet the construction of “barrier material composition.” None of these disclosures even suggests that the base of Wilson’s patch is rigid as Patent Owner suggests. To begin with, the fact that the housing is “more rigid” provides no information about the absolute rigidness of the patch. See Ex. 1009, 9:16–21. As for the disclosure that the patch is contoured (id. at 3:35–67), Patent Owner provides only attorney argument to support its contention that the contour demonstrates that Wilson’s patch must be so rigid that it cannot be meet the claim limitation. In contrast, Petitioner demonstrates that Wilson discloses using the exact same materials described in the challenged patent (see Ex. 1001, 6:33–58 (noting “[e]lastomeric materials useful for forming the intermediate layer 24 include but are not limited to gum rubber, vulcanized natural rubber SBR . . . or comparable materials”); Ex. 1009, 3:49–55 (noting the patch may be constructed from natural rubber (NR), a preferred mixture of chlorobutyl rubber and natural rubber (CR/NR), or a preferred mixture of SBR and natural rubber (SBR/NR)), and provides detailed testimony from its expert to support its contentions (see Ex. 1003 ¶¶ 114–119).
