“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.

- Obviousness (§103) › Analogous artAnalogous artDecided for petitioner
“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.

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

Petitioner’s argument and evidence, at this juncture, reasonably explain the reasons to combine under precedent that there is a motivation to combine when “a known 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.’” See Intel Corp. v.

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. Specification’s discussions of “playfield” cited by Patent Owner use non-limiting language such as “for example” and “may” in describing the playfield.

“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.

“To show that the claims of the ’109 patent are unpatentable for lack of written description, Petitioner would have needed to show that the specification as filed (i.e., the ’420 application) fails to reasonably convey to those skilled in the art that Patent Owner had possession of the claimed subject matter as of the July 3, 2023, filing date. Petitioner did not. Pet. 23– 24. Nor does Petitioner’s declarant offer testimony that could support such a showing. See Ex. 1003 ¶50 (“I have been asked to provide my opinions as to the state of the art in this field for purposes of determining what the inventors disclosed as their invention as of December 10, 2013.”), ¶51 (“Whenever I offer an opinion in this declaration about the knowledge of a POSA, the manner in which a POSA would have understood the claims of the ’109 patent or its description, the manner in which a POSA would have understood the prior art, or what a POSA would have been led to do based on the prior art, I am referencing the December 10, 2013 timeframe.”). Although the ’420 application is essentially identical to the ’767 application, the person of ordinary skill in 2013 is not the same as in 2023. See Ariad, 598 F.3d at 1351 (“[T]he [written description] test requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” (emphasis added)).

“Nevertheless, we determine that the contrary evidence Petitioner has cited suffices to establish a reasonable likelihood of success at this preliminary stage of the proceeding. In this regard, we also note Dr. Jain’s testimony — currently unrebutted — that an ordinarily skilled artisan would have known, based on Tokunaga’s sequence comparisons of Factor C proteins, that “certain sequence differences between [Limulus polyphemus] and Tachypleus tridentatus were non-conservative (i.e., potentially giving rise to changes in function in terms of enzymatic activity of Factor C).” Ex. 1002 ¶ 94 (citing Ex. 1022, 157). We likewise note Dr. Jain’s testimony that such artisan would have recognized Tokunaga’s conclusion, regarding “immunological and biochemical properties” of Factor C proteins of the two different horseshoe crab species, to be “based on only gross biophysical-biochemical properties” that are not “granular enough” to predict functional properties such as residual activity in presence of specific ions.

“submitted in a different proceeding and in a different forum, and our rules contemplate objections to admissibility only after institution. See 37 C.F.R. § 42.64(b)(1) (“Any objection to evidence submitted during a preliminary proceeding must be filed within ten business days of the institution of the trial.”); also compare Fed. R. Evid. 801(c) (defining hearsay as a statement, not made at the current trial or hearing, “offer[ed] in evidence to prove the truth of the matter asserted”), with Fed. R. Evid. 801(d)(2) (excluding from hearsay statement offered against an opposing party where statement was made by “a person whom the party authorized to make a statement on the subject” or by a “party’s agent or employee on a matter within the scope of that relationship and while it existed”). Nevertheless, as discussed above, Petitioner has provided contrary evidence, including statements from Patent Owner’s patent application, suggesting that, “due to the various differences and diversity of biomolecules depending on the genus and species of the horseshoe crab,” it had not been possible “to accurately determine the full-length sequence structure, expression, and function of [Limulus] proteins and genes using conventional methods” more than 20 years after complete gene and amino sequences from two Tachypleus horseshoe crab species had been reported. Pet. 35 (citing, e.g., Ex. 1005 ¶¶ 12–17). Thus, even if we were to take the Frohman Declaration into account, we find that Petitioner has established a reasonable likelihood 28 of success that the ’767 application disclosures did not enable an ordinarily skilled artisan to make and use the invention of the challenged claim without undue experimentation. Furthermore, assuming that the disclosures in ’767 application would have enabled an ordinarily skilled artisan to express recombinant Limulus polyphemus Factor C protein in HEK293, we find Petitioner has established, sufficient for purposes of institution, that the disclosures do not enable an ordinarily skilled artisan to make such a protein exhibiting the “full scope” of the claimed residual activity, without undue experimentation. Patent Owner cites to disclosures in the ’767 application that (1) describe how to produce recombinant Factor C in HEK293 cells and measure residual activity, (2) suggest “Factor C expressed in mammalian cells can have low susceptibility to activity inhibition by ions,” and (3) provide examples where residual activity met the required minimum. Prelim. Resp. 26–27, 32–34. Nevertheless, whether an ordinarily skilled artisan would have been able to make, based on these disclosures and without undue experimentation, a recombinant Factor C protein having residual activity encompassed by claim 21 but higher — even significantly higher — than that achieved in the example, is a fact intensive issue that would benefit from further development during trial.15 See, e.g., In re” slip op. at 28

“We find the District Court’s reasoning persuasive, and we, like the District Court, decline to adopt Petitioner’s overly broad proposed construction. However, for purposes of deciding the dispositive fact issue before us, we need not determine the precise boundaries of “surrounding textile structure,” for example whether it completely or mostly encircles the textile element, and if “mostly,” what percentage of encircling is required. See Pet. Reply 2 (Petitioner characterizing Patent Owner’s position as “mostly” means over 50%); id. at 4 (Petitioner impliedly arguing that the “surrounding” need not be complete, i.e., 100%); PO Sur-reply 3–4 (Patent Owner arguing that “Zuckerman’s textile structures . . . each abut only about 25% of the periphery of Zuckerman’s blank.”). We find that a person of ordinary skill in the art would not understand the portion of Zuckerman’s strip 13 in purple to surround the green blank 11 (textile element) under any reasonable construction of “surrounding textile structure.” Dr. Pastore testifies that “Zuckerman discloses two separate textile structures adjacent the blank—one on each side . . . they abut only two sides of Zuckerman’s blank, with each structure abutting only about a quarter of the blank’s periphery,” and opines that “a POSITA would not have understood these two separate structures, designated by purple in the figure above, to be a textile structure ‘surrounding’ the blank [shown in green].” Ex. 2003 ¶ 54. We find Dr. Pastore’s tesimony credible as it is consistent with Zuckerman’s Figure and with the plain and ordinary meaning of “surrounding” and with the Specification of the ’749 patent (particularly Figure 9).

“In particular, we agree with Patent Owner that Cantor does not teach or suggest contacting a ‘tissue section’ with its beads, let alone that its beads could be contacted with a tissue section to identify spatial location. Prelim. Resp. 36–48. In this case, we are persuaded by the testimony of Dr. Cantor, sole inventor of Cantor (Ex. 2002 ¶ 29), that Cantor’s nucleic acid samples are made in bulk from the extraction of nucleic acids from a biological sample and mixed together “to create the sample nucleic acid prior to mixing that with the solid phase nucleic acids to capture molecule(s) from the sample nucleic acid.” Id. at ¶ 36 (citing EX.1031 1:5–6). More specifically, according to Dr. Cantor, “[f]or bulk-analysis methods, nucleic acids are extracted from the different types of cells within a tissue sample without preserving their spatial distribution.” Id. at ¶ 19. Dr. Cantor further explains that in bulk-analysis methods, the mixture is analyzed to determine if a particular nucleic acid was present in the tissue sample or not. They cannot, however, determine where the molecule was in the tissue sample. As such, bulk-analysis techniques provide no information about spatial location of biological molecules in tissue samples. This is in contrast to spatial analysis methods such as those claimed in the ’879 patent which can determine both if a biological molecule was present in a tissue sample and where the molecule was in the tissue sample. Id. at ¶¶ 16–17. Although we recognize that Cantor discloses “providing the beads according to an (X,Y) array” (Pet. 24, 30–31 (citing to Dr. Puglisi, Ex. 1102 ¶¶ 133, 155, respectively), this disclosure makes no mention of using this array to map where the nucleic acids of Cantor came from relative to the original sample, let alone when that original sample is a tissue. See e.g. Ex. 1031, 17. The only mention of “tissue” made in Cantor is in reference to where the sample may be obtained, for example, “[t]he biological sample can be in any form, including without limitation a solid material such as a tissue.” Id. at 6. Cantor provides no teaching, however, regarding how to use a tissue sample with the probes and methods described in Cantor to identify where the target nucleic acids of Cantor were spatially located within the tissue section itself. See Ex. 2002 ¶¶ 142, 143 (Dr. Cantor testifying that (1) “a POSA would only be able to determine where on the array a target nucleic acid was captured, but not where in the original tissue section the nucleic acid came from,” because “all information about the spatial location of a target nucleic acid in a tissue sample is lost when the nucleic acid sample is prepared as Cantor teaches”; and (2) “Cantor [] does not teach or suggest contacting its solid supports (e.g. beads) with a tissue section and certainly not with its beads at known locations to obtain spatial information.”).” slip op. at 23
