    “Petitioner contends that one of ordinary skill in the art “would have possessed at least a four-year degree in electrical engineering or a closely related field, and at least two years of experience in semiconductor device design.” Pet. 5 (citing Ex. 1003 ¶¶ 67–69).

Cir. 2011). “This is so because inventions in most, if not all, instances rely upon building blocks long since uncovered, and claimed discoveries almost of necessity will be combinations of what, in some sense, is already known.” KSR, 550 U.S. at 418–419. On the other hand, an obviousness analysis “need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.” Id. at 418; accord In re Translogic Tech., Inc., 504 F.3d 1249, 1259 (Fed. Cir. 2007). However, a petitioner cannot satisfy its burden of proving obviousness by employing “mere conclusory statements.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir. 2016). Instead, a petitioner must articulate a reason why a person of ordinary skill in the art would have combined or modified the prior art references. In re NuVasive, Inc., 842 F.3d 1376, 1382 (Fed. Cir. 2016); see also Metalcraft of Mayville, Inc. v. The Toro Co., 848 F.3d 1358, 1366 (Fed. Cir. 2017) (“In determining whether there would have been a motivation to combine prior art references to arrive at the claimed invention, it is insufficient to simply conclude the combination would have been obvious without identifying any reason why a person of skill in the art would have made the combination.”); Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015) (“[O]bviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.”) (citing InTouch Techs., Inc. v. VGO Commc’ns, Inc., 751 F.3d 1327, 1352 (Fed. Cir. 2014)). In arguing for the obviousness of claim 1 over the combination of Bonn and Mizuta, Petitioner argues that a person of ordinary skill in the art would have modified Bonn to perform high-frequency signal amplification. Pet. 19–25. In particular, Petitioner argues that a person of ordinary skill in the art “would have found it obvious to modify the circuit of Figure 1 [of Bonn] and use Figure 7’s structure for high frequency signal amplification in place of mixer 40,” followed by additional modifications to the circuit of Figure 1. Id. at 22–25. These additional modifications include removing LO port 55, removing FET 20 (along with voltage source 80, capacitors 16, 26, and 34, resistor 18, and inductors 22 and 24), removing capacitor 34 and shorting gate structure 324 to ground, and removing resistors 46 and 48 and shorting terminal 51 to ground. Id. According to Petitioner, the motivation for these modifications was that “Bonn . . . teaches using its dual gate structures for signal amplification without signal mixing.” Id. at 22 (citing Ex. 1006, 11:26–37). On the record developed at trial, we disagree. Bonn does, as Petitioner argues, teach that “the dual gate FET structure of the present invention can be tailored to provide superior performance over the prior art dual gate FET structures in high frequency signal mixing as well as other applications such as high frequency signal amplification.” Ex. 1006, 11:33–37. But the tailoring that Bonn refers to relates to changes to the structure of the field-effect transistor itself, not to the circuitry surrounding that transistor. Id. (teaching that the reason that “the dual gate FET structure of the present invention can be tailored” is that “the parameters such as gate width, dopant concentration, and channel depth, under each gate of the dual gate FET are individually adjusted for optimum performance”). Thus, although Bonn might have motivated a person of ordinary skill in the art to have made changes to the dual-gate FET itself, we are not persuaded that it would have motivated the additional changes to the circuit of Bonn’s Figure 1.” slip op. at 11

  • Strike new argumentNew argument disregardedDecided for patent owner

    “Mishra’s Figure 5 is a second gate in favor of a new position. Petitioner’s new argument is that a person of ordinary skill in the art would have found it obvious to connect the field plate of Mishra’s Figure 5 to the source instead of the gate, converting the field plate into a second gate. Compare Pet. 83 (equating “drain side gate” with “field plate 66, Figure 5”), 86–88 (identifying field plate 66 as a “second gate”), with Reply 21–22 (identifying only the embodiment of Mishra’s Figure 10 as a source-connected field plate), 22–23 (arguing that Mishra teaches that the Figure 5 embodiment “could be arranged as ‘a single transistor with a dual gate structure’”). Although “the introduction of new evidence in the course of the trial is to be expected in inter partes review trial proceedings,” Genzyme Therapeutic Prods. LP v. Biomarin Pharm. Inc., 825 F.3d 1360, 1366 (Fed. Cir. 2016), the shifting of arguments is not, Wasica Fin. GmbH v. Cont’l Auto. Sys., Inc., 853 F.3d 1272, 1286 (Fed. Cir. 2017). Accordingly, Petitioner’s change of arguments here is inappropriate. Moreover, even if we were to consider Petitioner’s inappropriate new argument, we would conclude that Petitioner does not support the argument with sufficient evidence. “Whether [an obviousness ground] is based on combining disclosures from multiple references, combining multiple embodiments from a single reference, or selecting from large lists of elements in a single reference, there must be a motivation to make the combination and a reasonable expectation that such a combination would be successful, otherwise a skilled artisan would not arrive at the claimed combination.” In re Stepan, 868 F.3d 1342, 1346 n.1 (Fed. Cir. 2017). Petitioner’s new argument relies on a person of ordinary skill in the art modifying the Figure 5 embodiment of Mishra to connect the field plate to the source rather than the gate. Reply 21–24. Petitioner does not, however, show that a person of ordinary skill in the art would have had a motivation to make this modification or a reasonable expectation that this combination would be successful. Id. Petitioner argues instead that “[n]o ‘reason’ is needed.” Id. at 24. Thus, Petitioner does not show by a preponderance of the evidence that claim 1 would have been obvious over the combination of Mishra and Ren.” slip op. at 19

    “According to the ’713 patent, “[p]urge tower 24 itself may be . . . recycled or otherwise discarded as desired.” Ex. 1001, 8:27–28. This description provides some support for Patent Owner’s view, because a purge tower too intimately integrated with the part would be difficult or impossible to recycle or discard. This is further supported by the ’713 patent’s statement that “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Id. at 8:30–34. It also is supported by Dr. Hickner’s testimony that the ’713 patent “clearly shows . . . the 24 purge tower separated from the part” and that “the purge tower is a separate physical object.” Ex. 2016, 28:8–10, 64:1–9. On the other hand, there is evidence supporting Petitioner’s view that, as long as the purge tower is generally separate from the part and the support structure, it may still make contact with those portions of the print. As noted above, “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Ex. 1001, 8:30–34. This language does not exclude locations adjacent to or in contact with the part or the support structure. Thus, determine that a “purge tower,” as that term is used in the context of the ’713 patent, may not be an integrated portion of a printed part or support structure but need not be free of all contact with the printed part or support structure.” slip op. at 9

  • BurdenNot shown unpatentable

    “There is evidence of record to support both Petitioner’s view and Patent Owner’s view. On the record developed at trial, however, we cannot say that the preponderance of the evidence favors Petitioner, who bears the burden of proof. See 35 U.S.C. § 316(e). Accordingly, Petitioner has not shown by a preponderance of the evidence that KISSlicer teaches printing a layer of a purge tower each time the printer switches one extruder to the operating mode. Because proving the obviousness of claims 1 and 16 requires such a showing, Petitioner has not shown by a preponderance of the evidence that claims 1 and 16 would have been obvious over the combination of Priedeman and KISSlicer. 5. Analysis of Remaining Claims Claims 2, 6, 7, 9, and 17 all depend, directly or indirectly, from claim 1 or claim 16. Accordingly, they all include the limitations of either claim 1 or claim 16. Because, as discussed above, Petitioner has not shown that the combination of Priedeman and KISSlicer teaches or suggests all the limitations of claims 1 and 16, Petitioner also has not proven by a preponderance of the evidence that claims 2, 6, 7, 9, and 17 would have been obvious over that combination of references.” slip op. at 21

    “We agree with Petitioner that the substitute claims are broadening. Because the amended wording only requires the key request to be made “in response to detecting” the boundary, rather than “ahead of” the boundary, the request can occur before or after the boundary. This is not a fanciful or unlikely possibility — such delayed requests are specifically contemplated by the ’178 patent: [I]f the packager 104 is unable to obtain a new content encryption key from the WFM 102 prior to the expiration of the current content encryption key, the packager 104 will continue to use the current content encryption key until such time as it is able to obtain a new key from the WFM 102. Ex. 1001, 6:32–37. It should be noted that the fixed period duration for key rotation may be viewed as a "target" period, as the packager 104 may not expire a key on the exact boundary.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successUnpatentableMotivation foundUnpatentable

    “We agree with Petitioner that claim 43 is obvious over the combination of Conlon, Miller, and Fong. The Federal Circuit stated, “[i]n this context, ‘normalization’ generally refers to de-duplicating and simplifying database entries (for instance, combining entries for ‘car’ and ‘automobile’).” Appeal Dec. 4 (cited at Pet. Response Br. 5). This is consistent with the disclosure in the ’433 patent. E.g., Ex. 1001, 16:55– 17:24 (discussing, for example, “recogniz[ing] that the differently named data elements in different structures are actually the same data element . . . is referred to as normalizing the names of the same data elements,” “recogniz[ing] that the same named data elements in different structures are actually different data elements . . . is referred to as normalizing the names of the different data elements,” and “normalizing multiple single data elements”). This is also consistent with how Fong describes “normalization.” Ex. 1029, 76 (The “Function” of “Normaliz[ing] the collection of entities” is to “[r]emove redundancies and detect errors”); see also Ex. 1057 ¶ 226. Patent Owner’s arguments that Fong’s normalization is “different” from the normalization described in the ’433 patent does not persuasively rebut Petitioner’s arguments. As Petitioner points out, Patent Owner does not provide a construction for “normalization,” despite claiming that the term is “defined” in the ’433 patent. Pet. Remand Resp. Br. 6; PO Remand Br. 13. Moreover, although Patent Owner purports to identify differences between the ’433 patent and Fong, the “normalization” applied is expressly recited in limitations [43.1.1], [43.1.2], and [43.2], and the subsequent actions taken on those normalized databases (i.e., comparing and recording) are recited in limitations [43.3]–[43.5]. That is, the “normalization” required by the claim is reflected in the claim language itself, and is broader than argued by Patent Owner. See In re Baxter Travenol Labs., 952 F.2d 388, 391 (Fed. Cir. 1991) (“It is not the function of this court to examine the claims in greater detail than argued by an appellant, looking for nonobvious distinctions over the prior art”). Patent Owner does not explain how these purported “differences” (e.g., that Fong may require the use of “database keys,” “identifiers,” “entities,” or determining ‘non-key attributes’ from key attributes) impacts the claim language, or Petitioner’s showing. See EWP Corp. v. Reliance Universal Inc., 755 F.2d 898, 907 (Fed. Cir. 1985) (A prior art reference “must be considered for everything it teaches by way of technology and is not limited to the particular invention it is describing and attempting to protect”). For the same reasons, as well as those set forth by Petitioner, we are also not persuaded by Patent Owner’s arguments that each DBMS requires a normalization process that is customized for it. Pet. Remand Resp. Br. 6–7. These arguments by Patent Owner also are not commensurate with the scope of the claim language, which does not recite a DBMS, and generally recites “normalizing” or “normalized” without regard to the DBMS. Id. Dr. Jansen provides an example of a database in unnormalized form that is converted into a normalized form, based on Fong’s four conditions, as applied to the claim language. See Reply 31–35; Ex. 1057 ¶¶ 226–261. Therefore, we are not persuaded by Patent Owner’s arguments that Petitioner has not explained how the example maps onto the limitations. PO Remand Resp. Br. 6–12. Patent Owner’s complaint that Dr. Jansen created the graphic in the example does not undermine Petitioner’s showing. E.g., Trial Practice Guide,14 I.G., (“Experts may testify about the teachings of the prior art and how they relate to the patentability of the challenged claims.”). We find Dr. Jansen’s testimony credible and persuasive in explaining why the combination of Conlon and Fong teaches the claim limitations. After considering the properly presented evidence and arguments of the complete record, we determine that Petitioner has shown, by a preponderance of the evidence, that the combination of Conlon, Miller, and Fong teaches the limitations in claim 43, that one of ordinary skill in the art would have been motivated to combine the teachings of Conlon, Miller, and Fong, and that claim 44 would have been obvious over Conlon, Miller, and Fong. 2.

    “Patent Owner’s arguments do not undermine Petitioner’s showing. Patent Owner did not specifically challenge Petitioner’s contentions as to the sufficiency of Conlon’s disclosure for claim 1410 in the Patent Owner Response. In the Sur-replies, Patent Owner argues that the claim requires that at least some relationships are created “automatically,” and “these automatic embodiments . . . are represented in this group of claims.” Sur-reply 9. Along these lines, in the additional briefing Patent Owner argues that Conlon does not teach “automatic,” but merely teaches “semi-automatic.” PO Remand Br. 9–10. The crux of Patent Owner’s argument, however, is that the Federal Circuit did not properly construe the limitation, and ignored certain disclosures in the ’433 (and ’680) patent. Id. at 10–11; see Pet. Remand Resp. Br. 1–4; PO Remand Resp. Br. 4–5. The Federal Circuit held that “the dictionary routine claims can be satisfied by mere use of a lexical database, and do not also require the automatic creation of additional definitions.” Appeal Dec. 10. Moreover, the statements from Conlon that Patent Owner relies upon relate to creating a database, not using the database. See id. As discussed above, on remand we are directed to apply the Federal Circuit’s construction. Patent Owner does not explain 10 As discussed in the original Final Written Decisions, Patent Owner raised several arguments that generally applied to all the claims, challenging, for example, the level of ordinary skill in the art, whether Conlon, Miller, and Beckwith were analogous art, and several general arguments relating to Conlon and the motivation to combine Conlon with a DBMS. See Final Dec. 14–23, 25–27. We were not persuaded by Patent Owner’s arguments; the Federal Circuit affirmed, determining that our findings were supported by substantial evidence. Appeal Dec. 14–16. why Petitioner’s contentions are not persuasive in light of the Federal Circuit’s construction of this limitation. In addition, Patent Owner argues in the Sur-replies that “[c]laims 14– 19 are not disclosed by the proffered prior art” and cites to paragraphs 78–83 of the Ranka Rebuttal Declarations. Sur-reply 10. As discussed in the original Final Written Decisions, Patent Owner’s reliance on six paragraphs of Dr. Ranka’s Rebuttal Declarations is an improper incorporation by reference, as Patent Owner did not discuss that testimony or further elaborate on these arguments in the Sur-replies. 37 C.F.R. § 42.6(a)(3); Cisco Systems, Inc. v. C-Cation Techs., LLC, IPR2014-00454, Paper 12 at 9–10 (PTAB Aug. 29, 2014) (informative); see, e.g., Final Dec. 37–39, 45, 48–50, 52. Therefore, we will not consider arguments that are not made in the Sur-replies, but are instead improperly incorporated by reference to the cited paragraphs in Dr. Ranka’s Rebuttal Declarations. Accordingly, after considering the evidence and arguments of the complete record, we determine that Petitioner has shown, by a preponderance of the evidence, that Conlon teaches limitation [14.3], and that claim 14 would have been obvious over Conlon.” slip op. at 21

    “information” should be given its plain and ordinary meaning as “data,” and that Patent Owner’s narrower construction of “first information” and “second information” lacks sufficient support in the intrinsic record. We agree with Petitioner that the ’802 patent Specification defines “information” as data when it uses the phrase “information (i.e., data).” See Ex. 1001, 5:60–62 (“Information (i.e., data) to be transmitted may be received in a baseband digital system 250, such as a wireless digital baseband processor.” (emphasis added)), 11:30–32 (“In this example, the signals 911 and 912 carry the same information (data).” (emphasis added)).

See Pet. 76–77 Ex. 1003 ¶ 235. Petitioner’s only rationale for this modification to Fernandez is that “[a] single amplifier has several advantages compared to multiple amplifiers, including lower complexity, a single (vs. multiple) potential point of failure, and lower cost,” and that one of ordinary skill “would have found a single amplifier to be a simple matter of design preference.” Pet. 76–77.

    “We find credible and agree with Dr. Cooklev’s testimony that the predistortion signals from tables 17-1 and 17-2 “are cancelled out by Suzuki’s amplifier” 28. Ex. 2013 ¶ 50. Dr. Cooklev supports his opinion by referring to paragraph 1 of Suzuki, which states that Suzuki’s invention is directed to “a multi-band lookup table type predistorter” (such as the one implemented using lookup tables 17-1 and 17-2 in Figure 6) that “compensates for a distortion of a power amplifier.” Ex. 2013 ¶ 54; Ex. 1004 ¶ 1. Dr. Cooklev’s opinion is also supported by paragraph 3 of Suzuki, which explains that a conventional digital predistorter uses a lookup table “for linearizing non-linear characteristics of an amplifier.” Ex. 1004 ¶ 3; Ex. 2013 ¶ 54. Dr. Cooklev further supports his opinion by relying on Suzuki’s disclosure in paragraph 46 that power amplifier 28 is “subject to distortion compensation” by the predistorter, and that distortion components in the signal output by the amplifier are canceled by “distortion compensation data [that] are read out from the lookup tables 17-1 and 17-2 and provided to the adders 13-1 and 13-2, respectively.” Ex. 1004 ¶ 46; Ex. 2013 ¶ 54. And, Dr. Cooklev’s opinion is supported by Suzuki’s disclosure in paragraph 47 that the distortion compensation added by adders 13-1 and 13-2 add the distortion compensation data from lookup tables 17-1 and 17-2 “to perform distortion compensation (addition of predistortion)” to “signals to be transmitted.” Ex. 1004 ¶ 47; Ex. 2013 ¶ 54. Petitioner agrees that the distortion compensation data from lookup tables 17-1 and 17-2 “are added to the respective frequency band from” input signal ST “in order to predistort the output signal, which is then transmitted,” and does not dispute that the distortion compensation data from lookup tables 17-1 and 17-2 is ultimately cancelled out by the distortion created by amplifier 28. Pet. Reply 8. In light of the above evidence, we agree with Patent Owner that Suzuki’s distortion components from lookup tables 17-1 and 17-2 in Figure 6 (which Petitioner relies on for the first and second digital signals in limitations 10a and 10b) are cancelled out by the distortion created by power amplifier 28 before the signal is ultimately transmitted. We agree with Petitioner that these first and second digital signals include data in the form of distortion compensation data. However, because these signals are cancelled by the distortion from amplifier 28 before transmission, the data from these signals is never transmitted. Thus, the first and second digital signals identified by Petitioner (the distortion compensation data from lookup tables 17-1 and 17-2) do not comprise data “to be transmitted,” as limitations 10a and 10b require.” slip op. at 35
