    “We are persuaded that Petitioner has shown a reasonable expectation of success in the combination of Froitzheim and Gan. Petitioner explains that the combination of Froitzheim and Gan simply replaces one emitter, i.e., Froitzheim’s diffused emitter, with the polysilicon emitter of Gan. Pet. 36. According to Petitioner, a person of ordinary skill in the art would have also readily understood how to replace a diffused emitter with a polysilicon emitter and oxide layer [and] would have understood that instead of diffusing boron into the substrate’s back side as taught by Froitzheim, a [person of ordinary skill in the art] would instead follow the manufacturing technique taught by Gan. Pet. 37 (citing Ex. 1005, 246). Petitioner explains that the Gan processes are well-known and routine, and Dr. Holman states that “modifying Froitzheim in view of Gan simply involves using Gan’s known technique of a polysilicon emitter and oxide layer with Froitzheim’s known solar cell to improve Froitzheim’s solar cell in a similar way.” Pet. 37 (citing Ex. 1003 ¶ 144). For example, Petitioner directs our attention to “multiple instances” in which oxide layers and polysilicon emitters have been implemented successfully in the art. Pet. 37 (citing Ex. 1005, 246; Ex. 1006 ¶ 22; Ex. 1046, Abstr., 1121; Ex. 1003 ¶ 145). Furthermore, Gan’s statement that “cell performance can be improved if the diffused-emitter is replaced with the polysilicon emitter” and “polysilicon emitters with low J0 and ρc can be obtained with a very small fraction of interfacial oxide breakup” indicate a reasonable expectation of success. Ex. 1005, 245, 249. Gan also states that “polysilicon emitters with these qualities can be quite useful for silicon concentrator solar cells.” Ex. 1005, 249. Thus, we are persuaded that Petitioner has demonstrated that a person of ordinary skill in the art would have had a reasonable expectation of success in combining Froitzheim and Gan.” slip op. at 17

    “We are not persuaded the record evidence rises to the level of a teaching away. “A reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). And “teaching away” requires more than the mere expression of a general preference.” Galderma Labs., L.P., v. Tolmar, Inc., 737 F.3d 731, 738 (Fed. Cir. 2013). Notably, our reviewing court has determined that a reference can distinguish prior art in order to show the novelty of an invention without teaching away from combining the prior art with the invention disclosed in the reference. See Ricoh Co. v. Quanta Computer Inc., 550 F.3d 1325, 1332 (Fed. Cir. 2008). Here, Li prefers a “heterogeneous PN junction” and states that “a PN junction is prepared by a low-temperature deposition method, which avoids a conventional diffusion process at 800–1000°C. Such high-temperature process will cause more defects or contamination in silicon material, which will affect the improvement of cell efficiency.” Ex. 1008, 4. But, Li’s preference for lower temperature diffusion processes does not amount to a teaching away from the broader disclosure. In fact, Li acknowledges that “[t]he silicon thin film can be prepared by any deposition method,” including conventional processes at higher temperatures. Ex. 1008, 4 (emphasis added). And, while Patent Owner asserts that “[d]eposition methods are not relevant to the parties’ dispute, which is over deposition temperature” (Sur-reply 17), the deposition method employed includes its deposition temperature. See Ex. 1008, 4 (Li describing “conventional” diffusion processes at temperatures of 800–1000° C). Thus, just because Li teaches one way of depositing its silicon thin film using a low-temperature deposition method does not mean that Li teaches away from high-temperature processes. Li’s teachings do not discredit or discourage high-temperature processes in a manner that may be said to teach away.” slip op. at 51

    “We are convinced Petitioner has shown that a person of ordinary skill in the art would have had a reason to combine the subject matter of Froitzheim and Gan for the reasons expressed by Petitioner (Pet. 42–48) and discussed above (see supra). Patent Owner’s arguments in response are not persuasive. Though Gan’s teachings are directed to silicon concentrator solar cells, the ordinarily skilled artisan would have understood Gan also refers to silicon solar cells in general. Compare Ex. 1007, 249 (stating “[t]he data in Fig. 6 are quite useful for silicon solar cells” and “cell efficiency is obtained for a backside contact solar cell”), with id. (explaining that “polysilicon emitters with these qualities can be quite useful for silicon concentrator solar cells”). Dr. Banerjee testifies that “the Skilled Artisan would interpret Gan as recommending the feature for solar cells in general” and “that its polysilicon emitter with interfacial oxide feature is beneficial for solar cell efficiency in general.” Ex. 1003 ¶ 146; Ex. 2023, 93:10–15. Furthermore, Dr. Ruby testified that when designing solar cells, he reviews published works in the field and would not necessarily limit his review to the type of solar cell being developed. Ex. 1066, 48:4–51:16. Q So you would agree that if you're developing a 1-Sun solar cell, it might be worthwhile to look at publications regarding concentrator solar cells? * * * THE WITNESS: Well, it would be advisable or suggest -- you know, it would certainly be worth -- worth looking at, although not all of the methods for creating solar cells -- concentrator cells are required for producing 1-Sun cells. So some things would be of use and many things would not. Ex. 1066, 51:7–16. That Dr. Banerjee and Dr. Ruby each testify that a person of ordinary skill in the art would have had reason to consult the teachings of both concentrator and non-concentrator solar cells—in fact describing such consideration as “advisable,” “suggest[ed],” and “worth looking at”—when designing a solar cell is dispositive of this issue. We acknowledge Dr. Ruby’s testimony that consideration of broader teachings may hinge on a specific application for the solar cells. Ex. 1066, 51:7–16. But the combination proposed here by Petitioner, which substitutes one known emitter for another, that is, a polysilicon emitter for a diffused emitter, to improve efficiency of solar cell performance, has been shown to have general applicability regardless of solar cell type.

    “The standard for demonstrating teaching away is, as Petitioner notes, high. “A reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the [inventor].” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). Under that standard, Patent Owner’s “teaching away” argument is unavailing. The permitted temperatures in Froitzheim include a range of 900°C-1200°C, which expresses a permitted range, rather than a discouragement or divergence from that range, and the Froitzheim range clearly encompasses the temperatures used by Gan. A reference will also “teach away” if it suggests that the developments flowing from its disclosures are “unlikely to produce the objective of the applicant’s invention,” which is not the case here. See, e.g., Syntex (U.S.A.) LLC v. Apotex, Inc., 407 F.3d 1371, 1380 (Fed. Cir. 2005). The record demonstrates that Gan’s teachings are consistent with Froitzheim’s and, in the proposed combination, likely to produce the desired objective. Pet. Reply 13. In sum, the evidence of record here does not support a conclusion that Froitzheim criticizes or discredits the use of the lower temperatures in its expressly stated range, or that an ordinarily skilled artisan would have been discouraged from considering the full range of Froitzheim’s identified temperatures. Nor does it support a conclusion that Gan’s temperature, which is within Froitzheim’s range of temperatures, amounts to a criticizing, discrediting, or discouraging that would constitute a teaching away.” slip op. at 28

    “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.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

    “We agree with Petitioner. Patent Owner’s proposal that the distal end of the delivery catheter “houses the prosthetic” is in tension with the express language of the claim because the proposed construction suggests that “houses” necessarily means more than “at least” part of the prosthesis is disposed in the distal end. Indeed, if “houses” was not more limiting than “at least partially disposed” there would be no need to further define the spatial relationship between the distal end of the catheter and the prosthetic valve. Petitioner further argues that the Patent Owner’s construction is improper because it “wrongly limits the term to require that ‘the proximal end includes a handle that controls the deployment of the implant.’” Pet. Reply at 3 (citing PO Resp. 37–38). Petitioner asserts that the claims do not recite a handle and the ’897 patent’s “specification makes clear that a handle is a separate, optional component that is not integral to a delivery catheter: inner tubular member ‘can’ be connected to handle 907 and outer tubular member ‘can be connected’/‘attach[ed]’ to outer sheath handle 908.” Id. (citing Ex. 1001, 20:19–29, 26:30–33, claim 10). We again agree with Petitioner. Although the specification describes an embodiment in which proximal end 905 of inner tubular member 904 can be connected to handle 907 and proximal end 902 of outer tubular member 901 can be connected to handle 908 (Ex. 1001, 20:19–26), it is generally improper to read limitations from specific embodiments into the claims. See Cadence Pharms. Inc. v. Exela PharmSci Inc., 780 F.3d 1364, 1369 (Fed. Cir. 2015) (“[E]ven if all of the embodiments discussed in the patent included a specific limitation, it would not be proper to import from the patent’s written description limitations that are not found in the claims themselves.” (internal quotations omitted)); SuperGuide Corp. v. DirecTV Enters., Inc., 358 F.3d 870, 875 (Fed. Cir. 2004) (“Though understanding the claim language may be aided by the explanations contained in the written description, it is important not to import into a claim limitations that are not a part of the claim.”). Furthermore, at the oral hearing, Patent Owner indicated that “the proximal end includes a handle that controls the deployment of the implant” part of its proposed construction is not necessary.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner

    “We decline to adopt Patent Owner’s proposed construction, which departs from the constructions in the Arkwright Lawsuit and the Delaware Lawsuit, which both require actual melting, not just softening, and construe “mix” to have its plain and ordinary meaning. Ex. 1038, 17; Ex. 1045, 8–11. Accordingly, we maintain our construction of the term “white layer” from the Institution Decision. Further, to the extent Patent Owner argues that our construction of “white layer” requires an actual transfer of an image onto a substrate (for example, after printing, using heat), we disagree. See, e.g., Reply 5; Tr. 32:15–33:19, 46:15–49:25. Although we construe the term “white layer” as comprising a polymer that melts and mixes “during application,” this merely reflects a property of the polymer that occurs, for example, once heat is applied to an image transfer sheet. It does not mean that transferring an image from a sheet to a substrate must occur to satisfy claims 1 and 13. We discuss this in more detail below with respect to our construction of the preamble of claims 1 and 13, and in our prior art analysis of these claims. We note, however, that Patent Owner states that “the parties’ disputes with respect to the construction of the ‘white layer’ make no difference to the Board’s resolution of this matter.” Resp. 23.” slip op. at 12

    “steps. Ex. 1012, 12:42–67. In its Response, Patent Owner argues that the order of the method steps, i.e., “providing an ink-jet transfer article,” “wherein the substrate member is peeled away,” “wherein the opaque first layer and the second layer are applied to the dark-colored or black receiving member,” and “wherein heat is applied” is sequential. Resp. 23–24. Patent Owner explains that “[t]his is because the Claim requires ‘that received indicia face upwards,’” and “[i]f one were to place the transfer so that received indicia faces upwards, but not remove the backing paper before applying heat, then the backing paper (sandwiched between the fabric and the transfer) would prevent the transfer from adhering to the fabric.” Id. In its Reply, “Petitioner does not dispute Patent Owner’s position that the step of ‘peeling’ the substrate is performed before the step of applying the opaque layer and second layer to the receiving member and the steps recited thereafter.” Reply 2. Both parties agree that the steps of method claim 19 must be performed in sequential order. Thus, we need not construe this aspect of the claim language because it is not in controversy.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble not limitingDecided for petitioner

    “Owner waited until the Sur-reply to address this issue with any level of specificity, which calls into question the timeliness of its argument. See PTAB Consolidated Trial Practice Guide (“CTPG”) (Nov. 2019) 73–74, available at https://www.uspto.gov/TrialPracticeGuideConsolidated (“Sur-replies should only respond to arguments made in reply briefs, comments on reply declarations testimony, or point to cross-examination testimony.”); Paper 10, 10 (“any arguments not raised in the response may be deemed waived”). Nevertheless, we disagree with Patent Owner that “ink-jet transfer” is essential to claims 1 and 13. Claims 1 and 13 are not method claims. Rather, as Petitioner argues, both claims are directed to an article of manufacture made of structurally complete components that does not require an ink-jet transfer, even though the article may be used for such a purpose. See Reply 2–4; see also Am. Med. Sys., Inc. v. Biolitec, Inc., 618 F.3d 1354, 1358–59 (Fed. Cir. 2010) (“A preamble is not regarded as limiting [] ‘when the claim body describes a structurally complete invention such that deletion of the preamble phrase does not affect the structure or steps of the claimed invention.’”) (citation omitted). The body of claim 1 does not reference “an ink-jet transfer” at all. See Ex. 1012, 11:35–41. And although claim 13 also recites that the article is “for transferring an image to a fabric material” and comprises a layer that is “ink-receptive,” these recitations are not essential to understanding the claim; nor do they show that the claim requires an ink-jet transfer. See id. at 12:13–14, 12:20–22. Rather, the first phrase merely recites an intended use of the article, and the second phrase merely describes a layer’s ability to receive ink. Accordingly, we determine that the preambles of claims 1 and 13 are not limiting. As such, Patent Owner’s arguments that the combined teachings of Akada and Takao fail to disclose or suggest an “ink-jet transfer” article are unpersuasive. See, e.g., Resp. 38, 41; Sur-reply 20–22. Even if we were to find the preambles limiting, Petitioner establishes that an “ink-jet transfer article” would have been obvious given the prior art disclosures. See Pet. 30, 45 (asserting that an ordinarily skilled artisan would have recognized that Akada’s and Takao’s thermal transfer printing method was interchangeable with an ink jet printing method); (citing Ex. 1001 ¶¶ 120–121; Ex. 1030, 3:26–29); Reply 24 (“Akada’s dye sublimation transfer sheets are ‘ink-jet transfer articles’ because they can effectively be printed on with ink-jet technology”), 29 (citing Ex. 1039 ¶ 27; Ex. 1019, 7:63–8:4) (“Takao itself teaches that its thermal transfer image-receiving sheet may receive the image in the form of a ‘hot melt ink layer of colorant, such as a pigment’”).” slip op. at 23
