“Patent Owner argues for a slightly different level of ordinary skill in the art: “a bachelor’s degree in electrical engineering, computer engineering, computer science, or a similar field, along with one to two years of experience developing or programming video games or video game systems, or similar types of computer systems.” PO Resp. 2 (citing Ex. 2006 ¶ 29). Patent Owner further argues that the person having ordinary skill in the art “may have additional education that might substitute for some of the experience, and additional experience might substitute for some of the educational background.” Id. (citing Ex. 2006 ¶ 29). According to Patent Owner, Petitioner’s proposal does not require experience in programming video games. Id. at 3. However, Patent Owner states, “[t]his difference does not materially affect the analysis presented below.” Id. We see very little difference between the parties’ respective proposals. We adopt Patent Owner’s marginally more specific proposal. Additionally, because we would reach the same conclusions under Petitioner’s proposal, we agree with Patent Owner that this does not affect our analysis.” slip op. at 9

“date of the ’662 patent, Ho is not a “printed publication” within the meaning of 35 U.S.C. § 311(b). PO Resp. 30–33; PO Sur-reply 15–16. The Federal Circuit has rejected this argument, holding that: a published patent application is, by its literal terms, a “printed publication.” So, when § 311(b) permits IPR challenges based upon “prior art . . . printed publications,” it includes within its literal scope challenges based upon a published patent application. And, by virtue of § 102(e)(1), a published patent application—this specific type of “printed publication”—is deemed prior art as of its filing date. Therefore, the plain language of §§ 311(b) and 102(e)(1) permits IPR challenges based upon published patent applications, and such published patent applications can be deemed prior art in IPRs as of their filing date. Lynk Labs, Inc. v. Samsung Elecs. Co., 125 F.4th 1120, 1127 (Fed. Cir. 2025). Thus, Petitioner asserts permissible grounds of unpatentability under 35 U.S.C. § 311(b) by arguing that claims 1–20 are unpatentable under 35 U.S.C. § 103(a) on the basis of Ho, which is a prior art printed publication, and either Aoki or Kim.” slip op. at 11

“A person having ordinary skill in the art would have combined Aoki’s teaching of using user-identification information as part of the request for an advertisement with Ho’s system, which also teaches a client device sending information to a server to request hot spot information, such as advertisements. See Ex. 1003 ¶¶ 103–107, 111, 114, 117. Because both Ho and Aoki are directed to improvements in game design and monetization from using advertisements (id. ¶ 106; Ex. 1004, 1:26–28; Ex. 1005 ¶¶ 6–8), a person having ordinary skill in the art would have looked at both Ho and Aoki and combined the relevant features with a reasonable expectation of success (Ex. 1003 ¶¶ 103, 106, 117). A person having ordinary skill in the art would have appreciated that using Aoki’s teaching of sending user-identification information with Ho, which includes sending information with a request for information relating to interactive information elements (hot spots), allows for targeted advertisements, which was a known advantage in advertising.

“Reply ignore the express statement in the Petition characterizing sensors 36 in Wedekind as “a source external to the building.” Sur-reply 2 (quoting Pet. 28), 3. Patent Owner also argues this is a new argument that we should disregard. Sur-Reply 2. We disagree. Although Patent Owner is correct that Petitioner contends Wedekind’s outside air temperature sensors 36 are a source external to the building, that is not the only argument Petitioner presents. In the Petition, Petitioner contends more generally that Wedekind’s outside air temperature sensors 36 “measure the outside air temperature.” Pet. 28. Petitioner also argues that Ehlers provides weather data including outside temperatures, and that the source of the data is a weather service provider that is external to the building. Pet. 32 (citing Ex. 1008, 9:53–54, 35:13–17). Petitioner further argues that it would have been obvious “to replace Wedekind’s outside temperature sensors 36 with receiving outside temperature data from a network connection,” as Ehlers teaches. Pet. 32. In view of this, we agree with, and are persuaded by, Petitioner’s argument that it does not rely only on Wedekind to meet the limitation that “the second data from the network connection is collected from a source external to the building.” Reply 10. Additionally, the presence of these arguments in the Petition undermines Patent Owner’s assertion that Petitioner is attempting to present new arguments in the Reply. Similarly, Petitioner acknowledges in the Petition that Wedekind does not expressly teach the second data is received from a network connection, and, therefore, relies on Ehlers’ disclosure of receiving data from a network connection. Pet. 30; Reply 11. Patent Owner does not dispute that Ehlers discloses receiving weather data from a network connection. See PO Resp. 15–28; Sur-reply 3–8. In view of the foregoing, Petitioner has demonstrated persuasively that the combined disclosures of Wedekind and Ehlers teach or suggest “the one or more processors further configured to receive a second data from a network connection, wherein the second data from the network connection is collected from a source external to the building” claim 1 requires.” slip op. at 20

“We find Petitioner’s arguments to be persuasive. Petitioner presents undisputed evidence, based on the disclosure of Wedekind and Ehlers, that obtaining outside temperatures either from local sensors or over a network was known in the art. Pet. 28–32; Ex. 1006, 4:45–47; Ex. 1008, 9:50–63. Petitioner also directs us to evidence, including in Ehlers itself, supporting Petitioner’s reasoning that replacing Wedekind’s outside air temperature sensors with a network-based weather data service would have saved the cost and effort of installing multiple sensors. Pet. 32; Ex. 1002 ¶ 103; Ex. 1008, 39:54–57; Reply 13. As Petitioner points out, Patent Owner does not directly challenge Petitioner’s argument and evidence that a person of ordinary skill in the art would have had reason to modify Wedekind in view of Ehlers to avoid the cost and effort of installing multiple sensors. Reply 13.5 Indeed, Patent Owner acknowledges that Wedekind “expressly indicates that there must be multiple sensors of outdoor temperature for sufficient accuracy in Wedekind’s complex computational model.” PO Resp. 26; Ex. 1006, 3:62–67. The need for multiple sensors in Wedekind 5 We recognize Patent Owner argues that a person of ordinary skill in the art would not have been motivated to connect Wedekind’s outside air temperature sensors 36 to a network because it would “increase costs.” PO Resp. 23–24. Patent Owner, however, presents this argument before it addresses Petitioner’s proposed combination of Wedekind and Ehlers. See PO Resp. 23–24 (referring to cost increases first, and addressing the proposed combination of Wedekind and Ehlers in the next paragraph). Thus, Patent Owner’s cost argument does not appear to address Petitioner’s assertion regarding cost savings in view of the proposed combination. Nor does Patent Owner present evidence regarding, or explain adequately, what costs it is referring to, or how those costs would increase. PO Resp. 23–24; Ex. 2005 ¶ 61. By way of contrast, Petitioner’s arguments regarding cost savings are supported by the disclosure of Ehlers itself. Ex. 1008, 39:54–57. strengthens Petitioner’s argument that a person of ordinary skill in the art, in view of Ehlers’ teaching regarding avoiding the cost and effort of installing multiple sensors, would have had reason to modify Wedekind in view of Ehlers. Additionally, Patent Owner’s own declarant characterized Ehlers’ discussion of “lowering the cost of installation and ongoing maintenance” as “teach[ing] away from external sensors.” Ex. 1023, 58:7–18. These arguments and evidence undermine Patent Owner’s assertion that Petitioner failed to provide any analysis as to why a person of ordinary skill in the art would have modified Wedekind in view of Ehlers. Sur-reply 3–4; PO Resp. 25–28. Petitioner also argues, and provides evidence in the form of testimony from Dr. Shah demonstrating, that a person of ordinary skill in the art would have been able to modify Wedekind’s system by connecting Wedekind’s processing means to a network connection such as Ehlers’ phone input or communications link, and would have obtained predictable results. Pet. 33; Ex. 1002 ¶ 104. Patent Owner does not dispute this evidence. To the contrary, Patent Owner appears to concede that the proposed combination would work, although not as reliably as Wedekind’s hardwired system. PO Resp. 25–26. As a result, and in the absence of any evidence or argument suggesting otherwise, we credit Dr. Shah’s testimony. Furthermore, Ehlers teaches, in connection with providing data obtained from a weather service provider over a network, that “[t]he data may be provided at regular intervals and be sufficiently localized for acceptable accuracy.” Ex. 1008, 9:58–60. This statement from Ehlers itself undermines Patent Owner’s arguments regarding alleged problems with transmitting data over networks and insufficient accuracy, including Patent Owner’s argument that Wedekind teaches away from the approach used by Ehlers. PO Resp. 25–28. Nevertheless, even if we were to give Patent Owner the full credit of its arguments regarding unreliable transmission of data over networks and data obtained from weather service providers being less useful than data obtained from sensors at a specific structure, obviousness “does not require that the motivation be the best option, only that it be a suitable option from which the prior art did not teach away.” PAR Pharm., Inc. v. TWI Pharm., Inc., 773 F.3d 1186, 1197-98 (Fed. Cir. 2014). As discussed above, Petitioner’s evidence and arguments demonstrate that using Ehlers’ network to transmit temperature data was at least a suitable option. For all of the foregoing reasons, we determine Petitioner has demonstrated persuasively that a person of ordinary skill in the art would have had reason to modify Wedekind in view of Ehlers, and would have had a reasonable expectation of success in doing so. iii.” slip op. at 25

Dines, 754 F.2d 353, 359 (Fed. Cir. 1985) (citing Field v. Knowles, 183 F.2d 593, 601 (CCPA 1950)); see also Mahurkar v. C.R. Bard, Inc., 79 F.3d 1572, 1577 (Fed. Cir. 1996) (corroboration requirement “arose out of a concern that inventors testifying in patent infringement cases would be tempted to remember facts favorable to their case by the lure of protecting their patent or defeating another’s patent”). Similarly, an inventor’s testimony alone is insufficient to establish an earlier reduction to practice. Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1169–71 (Fed. Cir. 2006). Instead, a party seeking to prove an actual reduction to practice must proffer evidence corroborating that testimony. Id. at 1170. The sufficiency of corroboration is determined according to a “rule of reason.” Price v. Symsek, 988 F.2d 1187, 1195 (Fed. Cir. 1993). This, however, does not dispense with the requirement that some independent evidence provide corroboration. Coleman, 754 F.2d at 360. The requirement of “independent” corroboration requires evidence other than the inventor’s testimony. In re NTP, Inc., 654 F.3d 1279, 1291–92 (Fed. Cir. 2011). 3. Discussion We find that Patent Owner has not met its burden of establishing that Mr. Kuster conceived and reduced to practice his invention prior to the filing dates of Hsiao or He. By itself, Mr. Kuster’s testimony is insufficient to establish that he reduced his invention to practice prior to the November 23, 2010, filing date or Hsiao or the June 2, 2010, filing date of He. “Throughout the history of the determination of patent rights, oral testimony by an alleged inventor asserting priority over a patentee’s rights is regarded with skepticism, and as a result, such inventor testimony must be supported by some type of corroborating evidence.” Woodland Tr. v. Flowertree Nursery, Inc., 148 F.3d 1368, 1371 (Fed. Cir. 1998) (quoting Price, 988 F.2d at 1194).

“We do not agree with this argument. “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” MCM Portfolio LLC v. Hewlett-Packard Co., 812 F.3d 1284, 1294 (Fed. Cir. 2015) (quoting In re Keller, 642 F.2d 413, 425 (CCPA 1981)). Moreover, “[a] person of ordinary skill is also a person of ordinary creativity, not an automaton,” so the fact that it would take some creativity to carry out the combination does not defeat a finding of obviousness. KSR, 550 U.S. at 421; see also ClassCo, Inc. v. Apple, Inc., 838 F.3d 1214, 1219 (Fed.

We find there is support for making this combination of He and Cheng in the testimony of Dr. Baker that addition of a controller is “conventional” in USB flash drives. Baker Decl. ¶ 167. We find that for the reasons given by Dr. Baker, a person of ordinary skill would have added a controller to He. We determine that the combination of He and Cheng teaches each limitation of claim 11.

“attorney argument, not evidence.” Pet. Reply 26. We agree. Patent Owner does not back up its argument with testimony or other credible evidence. To demonstrate long-felt need, a patentee must point to an “articulated identified problem and evidence of efforts to solve that problem” which were, before the invention, unsuccessful. Tex. Instruments v. Int’l Trade Comm’n, 988 F.2d 1165, 1178 (Fed. Cir. 1993). All Patent Owner proves, if anything, is that after the USB 3.0 specification issued, a number of companies rushed in to provide contacts that met the new standard. Patent Owner does not demonstrate that they failed where Mr. Kuster succeeded. In fact, there is no evidence that Mr. Kuster ever commercialized his invention.8 8 Victorinox never paid for the work Mr. Kuster did on the USB 3.0 memory device, and to Mr. Kuster’s knowledge, never marketed the product. Kuster Dep. 22:21–24:13. Patent Owner contends “Mr. Kuster’s invention filled the existing need for a durable yet slim USB flash drive compatible with USB 3.0 that was easy to manufacture.” PO Resp. 77. But instead of presenting independent evidence of failure of the others to solve known technical or manufacturing problems, Patent Owner relies on generalized statements concerning the need for USB 3.0 connectors and solutions by others that Patent Owner contends have not been successful.

“1. “interactive user interface” In the Decision on Institution, we construed the term “interactive user interface” (“IUI”) as “a display with which a user may interact to result in the portable device taking action responsively.” Inst. Dec. 19. The parties have presented additional arguments in additional briefing on the term’s construction, which we have further considered, and, as discussed below, we modify the interpretation of the term. See PO Resp. 7–16; Pet. Reply 1–3. a. Petitioner’s Assertions In the Petition, Petitioner asserts that the term “interactive user interface” should be interpreted as “a display with which a user may interact to result in the computer taking action responsively.” Pet. 14. Petitioner argues that this proposed interpretation is consistent with the plain and ordinary meaning of the term. Id. at 13. Petitioner also contends that although the term “interactive user interface” is not used in the ’969 patent specification, the specification consistently describes the terminal output component as a “display mechanism,” and the interactive user interface is presented on the terminal output component in the claims. Id. (citing Ex. 1001, 4:40). Petitioner contends that a number of displays in the ’969 patent respond to text inputs from an input component to elicit a responsive action, and refers to an example of the input of registration information in screen 515 in Figure 5, where, if the input is successful, follow-up screen 517 is produced, but otherwise there is an error message.

Reply 1. This is similar to the construction that Petitioner previously proposed in the Petition, however, Petitioner now proposes that the “computer” can be considered to be a “portable device,” and a “display” can also be considered to be a “presentation. See Pet.14. According to Petitioner, the claims require that the interactive user interface be presented on the terminal output component. Pet. Reply 1.

Id. at 2 (citing Ex. 1046, 52:11–55:13; Ex. 1001, 7:55–56). Petitioner asserts that the claims require that it is the portable device that responds to user interaction, with the “fourth program code” executing in response to user interaction with the interactive user interface. Id. Petitioner compares the claim of the parent ’047 patent, which was narrowed to refer to “the interactive user interface is configured to enable the user to cause the portable device processor to execute program code stored on the portable device memory,” to the claims here.

“As we discussed in IPR2018-01152 and IPR2018-01153, and incorporate herein (1152 Final Dec. 12–21), the broadest reasonable interpretation is what would be understood by one of ordinary skill in the art in the context of the entire disclosure. See Translogic, 504 F.3d at 1257. The ’558 specification and the context of claims 6, 8, and 13 and the related language of claim 19 support that the amplifier must be able to receive both the boosted supply voltage and the first supply voltage (a selective boost) as recited in the claims.

“On the full record, Petitioner has not provided sufficient or persuasive argument and evidence that Figure 6 is merely a more detailed implementation of Figure 5 such that a person of ordinary skill in the art would envision them as a single disclosure. Figure 6 specifically discusses a summing circuit operating on input current and offset current that differs from the voltage circuit signals shown in Figure 5. PO Sur-reply 13–14. We also note that feedforward node in Figure 6 differs from that shown in Figure 5. Indeed, Kwak expressly notes the differences and advantages between Figures 4 and 5 (showing summation of voltage signals) and Figure 6, which shows voltage signals converted into current signals before summation, stating that: In CMOS design, although three voltage signals can be added and then integrated as shown in Figs. 4 and 5, the simultaneous summation and integration of the signals at the node Vc, after the conversion of the three voltage signals into current ones, is advantageous, that is, the sensed output current of the linear amplifier, the feedforward current, and the high-frequency current through the ripple filter are added together and integrated at the node with the inverted polarity of the last one Ex. 1211, 2669. Kwak’s disclosure notes differences between the voltage signals of Figures 4 and 5 and the current conversion feedforward teachings shown in Figure 6. See id. On the full record, Petitioner has failed to persuasively establish that “a person of skill in the art, reading the reference, would ‘at once envisage’ the claimed arrangement or combination of elements” of claim 15 based on Kwak’s disclosures. See Microsoft Corp., 878 F.3d at 1068. Petitioner’s parallel citations to Figures 5 and 6 and joint discussion of the current summing and integration of Figure 6 and the voltage summing of Figures 5 (see Pet. 42–49), do not establish that Kwak shows the elements of the claim in an embodiment as arranged in the claims.

Petitioner’s arguments and testimony evidence (Ex. 1203 ¶ 96; Pet. 44–45 (citing Ex. 1203 ¶¶ 94–96)) fail to address sufficiently the differences between Kwak’s Figures 5 and 6.

“and agree with Patent Owner that the terms “re-routing the course” and “re-route the course” mean “to change at least a portion of the route of the course relative to a previous routing.” That is, there must be a first routing of a course and that routing must be changed by performance of the marine route calculation algorithm to avoid preselected conditions by identifying one or more non-user selected waypoints. The construction is consistent with the words of the claims. The claims do not merely require routing a course, but “re-routing the course.” The ordinary meaning of the prefix “re” is that something is being done again. See Tr. 18 (Petitioner agreeing that “if you put R-E in front of a word, normally that means it’s occurring a second time”). Although the claims do not explicitly recite both an original “routing” of a course that is changed by “re-routing the course,” the original “routing” is implicitly required by the use of the prefix “re.” See Tr. 34 (Patent Owner agreeing that although the claims do not explicitly require an initial routing, the initial routing is implicit in the use of “re-routing”), 44–45 (Petitioner agreeing that “re-routing” ordinarily implies an initial routing).” slip op. at 10

The other independent claims recite similar limitations. See Ex. 1001, claims 12, 20, 27.

“the art “would have appreciated the benefit of including multi-carrier modulation in the Wu system” because “Wu itself references the 802.11a standard as a multi-carrier OFDM scheme that is able to achieve data rates that are faster than the 802.11b transmission rates used in the Wu system.” Id. at 48 (citing Ex. 1120 ¶¶ 43–47, 65–68; Ex. 1108, 411). Petitioner contends that [w]ith this motivation in mind a [person of ordinary skill in the art] would have recognized that adding the multi-carrier 802.11a modulation scheme to the modulation schemes already available in the Wu system would have been a simple addition, if a technique was available for using a channel estimate obtained from data modulated according to a single carrier modulation scheme for acquisition of data modulated according to a multi-carrier modulation scheme[,] and supports that contention with testimony by Dr. Almeroth. Id. at 48 (citing Ex. 1120 ¶¶ 43–47, 65–68). Petitioner identifies such a technique as disclosed by Böhnke. Id. at 49. Böhnke “relates to the mapping of data and pilot symbols in an OFDM-system.” Ex. 1113, col. 1, ll. 4–5. Figure 2 of Böhnke is reproduced below. Figure 2 illustrates a sequence that includes a first OFDM modulated signal S1, a midamble MA that can be OFDM modulated or single-carrier modulated, and a second OFDM symbol S2. Id. at col. 4, ll. 36–41. The midamble can be used for the transmission of pilot symbols, which “are necessary for a channel estimation such as to effect coherent detection of e.g. OFDM-modulated signals,” and such pilot symbols can be created by a single carrier modulation with a known training sequence. Id. col. 1, ll. 7–9, col. 5, ll. 45–49, col. 5, ll. 61–63. Böhnke, thus, uses the channel estimation obtained from the single-carrier training sequence to detect multi-carrier OFDM symbols by matching bandwidth and performing synchronization. Id. at col. 2, ll. 43–45, col. 2, ll. 61–62. Petitioner reasons that the Böhnke channel-estimation techniques “provide a way to combine a high-rate, multicarrier OFDM data transmission scheme with a single carrier training sequence” and that [w]ith this background, a [person of ordinary skill in the art] investigating options for including the multi-carrier 802.11a standard in the Wu system would have appreciated that Bohnke’s channel estimation techniques could be applied to Wu’s single-carrier 802.11b preamble and used for acquisition of data modulated according to multi-carrier 802.11a.” slip op. at 12
