In particular, Patent Owner argues that a transmitter “implemented in a base station” is not “associated with the base station.” Id. at 31. Petitioner argues that Patent Owner offers no reason to believe that a transmitter “implemented in a base station” is not “associated with the base station.” Pet. Reply 4–5; see also id. at 3–6 (entire argument). A plain reading of a “model associated with a base station” would encompass a model that operates in a base station. We do not see anything in the ’704 specification that would indicate “associated with” has any special meaning, or has a meaning contrary to our understanding of the plain meaning. We do not see the word “associated” outside the claims, whereas we see the word “implement” throughout the specification, generally in reference to an actual use of a model (consistent with our plain reading). See, e.g., Ex. 1001, 5:35–39, 6:3–17, 10:55–11:3 (discussing “implementations” where the model or some other feature of the system is used in a particular way).

    “scenarios” (see PO Resp. 16–21), Patent Owner argues that “Jüschke does not disclose any association of the weight or bias parameters, . . . to any deployment scenario, and . . . base station” (id. at 19). For the reasons explained in our claim construction section above, we construe “deployment scenarios” to include “inline mode” models located within a base station, according to the list of deployment scenarios set out in the ’704 patent. See Ex. 1001, 2:38–65. The in-line deployment scenario depicted in Figure 6A of the ’704 patent bears a striking resemblance to the arrangement depicted in Figure 1 of Jüschke. In both figures, the analog radio signal is fed directly into the model and then the model directly outputs the signal to the amplifier. Compare Ex. 1001, Fig. 6A, with Ex. 1005, Fig. 1. As construed, the “deployment scenarios” represent the physical configurations of the device in which the model is found, such as “in-line.” Petitioner shows by a preponderance of the evidence that Jüschke’s similar in-line configuration is a “deployment scenario” as claimed because it teaches an inline model for a cellular system transmitter (i.e., base station). Pet. 26–29 (citing, e.g., Ex. 1005, Fig. 1, ¶¶ 6, 59; Ex. 1003 ¶¶ 146–147); see also Ex. 1001, 2:37–41 (stating that “[t]he particular deployment scenario[] may be . . . sending a radio transmission from a cellular base station that includes the . . . model . . . in an inline mode”).” slip op. at 26

  • BurdenNot shown unpatentable

    “Based on our claim construction analysis of claim 4, above, we agree with Patent Owner that claim 4 requires an actually transmitted signal and an update of the transmitter’s model. This claim construction eliminates Petitioner’s position regarding Holt teaching a modeled signal. See, e.g., Pet. Reply 17–23. We then turn to Petitioner’s argument that Holt teaches updating a model using an actually transmitted signal. See Pet. 59–60. There, Petitioner relies on a disclosure in Holt of an “actual communication channel 302 used to train the channel model 208.” Ex. 1006, 18:1–2. This is depicted in Figure 6 of Holt, in connection with a “fourth loss function” which is used to “train the decoder model.” Id. at 18:42–48; see generally id. at 17:58–18:51 (describing Figure 6). Whether training the channel model or the decoder model, Holt here does not disclose using the actual communication channel to train the encoder, i.e., transmitter. In sum, we find that Petitioner has not shown by a preponderance of the evidence that the prior art describes the claimed step of “obtaining a received radio signal,” and even if it did, Petitioner has not shown by a preponderance of the evidence that the prior art describes the claimed step of “updating the value of the model parameters” in the manner required by claim 4. Claims 12 and 20 are nearly identical to claim 4, and Petitioner’s ground fails for similar reasons. See Pet. 76. Claims 5, 6, 13, 14, 21 and 22 depend from claims 4, 12, and 20, and Petitioner’s ground fails for similar reasons as those claims. See id. at 77–80.” slip op. at 31

Petitioner asserts that one of ordinary skill in the art would have “approximately one or more years of professional experience with electronic and optoelectronic system design.” Pet. 3. But Petitioner does not appear to dispute the testimony of Patent Owner’s declarant, Dr. Bretschneider, that “the field of optoelectronics” is “broad and expansive and encompasses solar cells, optical fiber, and any application of LEDs, not just the design of LED packages.” Ex. 2020 ¶ 78. Therefore, one having experience with optoelectronic system design would not necessarily have experience designing LED backlights for LCD displays. We have also carefully considered Patent Owner’s arguments and evidence in support of its proposed definition of the level of ordinary skill in the art at the time of the invention. In light of our analysis of the prior art and the AAPA, we determine that Patent Owner’s requirement of “at least one year of practical experience in design of LED packages and one year of practical experience in design of thermal management systems for LEDs” is not sufficiently precise.

Rather, as discussed previously, we find that Kleve’s vehicle owner can set a restriction, such as the rental start period, prior to step 214 in Kleve’s Figure 2 and that such restrictions can be associated with the e-key. We also do not agree with Patent Owner’s argument that (1) Dr. Almeroth’s declaration testimony contradicts his deposition testimony or that (2) Dr. Almeroth “admitted his testimony was wrong.” See PO Sur-Reply 7 (citing PO Resp. 47–48 (citing Ex. 2022, 27:5–10, 27:21–28:1; Ex. 2021 ¶ 96)).

So you use typically and always. So always does not refer to all of the embodiments of Kleve, is that fair? A. I think a person of skill in the art could read Kleve and understand that there are probably multiple ways in which the flow of actions among the parties could occur. And I think thinking about a real world scenario, in most cases you have an agreement before you would generate an eKey, but maybe, maybe not. I don’t -- I don’t know that the real world is necessarily cut and dry. So reading -- a person reading Kleve would understand it’s describing embodiments where it’s scenario, but I don’t know that it would necessarily be a hard and fast rule in every embodiment or in the understanding a person of skill in the art would have. Id. at 28:3–20. There is nothing in the deposition testimony by Dr. Almeroth that appears inconsistent with his declaration testimony nor does there appear to be the kind of admission touted by Patent Owner. Instead, it is Dr. Malek who takes an overly narrow view of Kleve that appears inconsistent with Kleve’s disclosure when read as a whole. See, e.g., Ex. 2021 ¶¶ 82–88.

    “We agree with Patent Owner. Petitioner’s argument appears to be purely hindsight analysis based on the teachings of the ’659 patent and the limitations of challenged claim 6 because there is insufficient evidence or teachings in the cited prior art to suggest the sharing of virtual keys. Petitioner’s argument that having “rental microbusiness” implemented as a “smart phone application” that enables sharing virtual keys is insufficient to show obviousness, because, as noted by Patent Owner, certain embodiments in Kleve appear to discourage or even hinder the sharing of virtual keys. These embodiments require the use of credentials associated with the virtual key, where the credentials can be “facial recognition, voice print recognition, matrix barcode (ex. two-dimensional code), code word or phrase for speech recognition, temporary mobile web login IDs and password, or other types service.” See Ex. 1005 ¶ 37. Dr. Almeroth testifies that multiple people could be authorized on the same vehicle if they collectively rent a vehicle and that a person of ordinary skill in the art would “have been motivated to enable each user to share the virtual key with other authorized users associated with the same rental request.” Ex. 1004 ¶ 55. But given Kleve’s disclosure that the system handles key generation and distribution (Ex. 1005 ¶ 39), the evidence does not show that a person of ordinary skill in the art would have wanted to give this control to each authorized user who has received an e-key. “It is impermissible to use the claimed invention as an instruction manual or ‘template’ to piece together the teachings of the prior art so that the claimed invention is rendered obvious.” Fritch, 972 F.2d 1260, 1266 (Fed. Cir. 1992) (citing In re Gorman, 933 F.2d 982, 987 (Fed. Cir. 1991)). Kleve’s teachings undermine Petitioner’s position, and do not support a finding of obviousness. Accordingly, we determine that Petitioner has not demonstrated by a preponderance of the evidence that Kleve alone or in combination with Hatton would have rendered dependent claim 6 obvious to a person of ordinary skill in the art at the critical time.” slip op. at 39

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.

    “The motivation-to-combine analysis is a flexible one. See Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1379 (Fed. Cir. 2023). A motivation to combine may be found “explicitly or implicitly in market forces; design incentives; the ‘interrelated teachings of multiple patents’; ‘any need or problem known in the field of endeavor at the time of invention and addressed by the patent’; and the background knowledge, creativity, and common sense of the person of ordinary skill.” ZUP, LLC v. Nash Mfg., Inc., 896 F.3d 1365, 1371 (Fed. Cir. 2018) (quoting Plantronics, Inc. v. Aliph, Inc., 724 F.3d 1343, 1354 (Fed. Cir. 2013)). “[T]he motivation-to-combine 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.’” PACT XPP, 61 F.4th 1380 (citing KSR, 550 U.S. at 418). We find that Petitioner has shown by a preponderance of the evidence that a person of ordinary skill in the art would have been motivated to combine Rose with the GridLab references. See Pet. 64–67; Ex. 1003 ¶¶ 216–223. In particular, we agree with Petitioner and Dr. Bederson that applying Rose’s technique to the GridLab References would have been within the level of skill in the art, and that a person of ordinary skill in the art “would find it beneficial to index the new portlet [being suggested to be added by GridLab], as per Rose, and compare those indexing results to the existing portlets of the user’s portal, and suggest a tab or sub-tab for the new portlet in the user’s portal, or automatically place the portlet in a content-relevant tab or sub-tab in the user’s portal, as per Rose.” Ex. 1003 ¶ 222 (citing Ex. 1004 § 10.1.6 (40); Ex. 1012, 262–64, 267–68).

    “In the Decision on Institution, we adopted Petitioner’s proposed level of ordinary skill in the art, stating it was “consistent with the evidence of record, including the asserted prior art.” Dec. Inst. 7. Petitioner does not challenge Patent Owner’s modification to its proposed definition, and Petitioner’s expert, Dr. Drasler, agrees that experience in the field of prosthetic cardiovascular implants would have included experience with transcatheter prosthetic cardiovascular implants as well as delivery systems and methods used to implant such prostheses. See generally Pet. Reply; Ex. 2048, 11:6–12:1. Thus, based on our review of the complete record, we adopt Petitioner’s definition of the level of ordinary skill in the art, modified as proposed by Patent Owner.

  • 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.

    “The parties dispute the scope of “independent.” Petitioner argues that using separate current setting signals for separate devices describes the “independent” aspect of these claims. Pet. 31–35; see also Pet. Reply 3–9 (setting forth claim construction arguments). Patent Owner argues that the ’132 patent does not set forth a special definition for “independent” and, therefore, that the plain meaning applies—“not determined or influenced by someone or something else.” PO Resp. 9–10 (citing Ex. 2005). Thus, Patent Owner argues that “independent of” means “not determined or influenced by.” PO Resp. 8–17; PO Sur-reply 2–7. As discussed below, we conclude that Petitioner has proven obviousness of the subject matter in claims 1–16 and 18 under Patent Owner’s proposed construction, and the deficiencies in Petitioner’s contentions for claim 17 are not related to the definition of “independent.” Thus, we need not resolve this claim construction dispute to issue a final written decision on all claims.

    “At institution, we preliminarily agreed with Petitioner that these phrases are means-plus-function. Inst. Dec. 13–15. Patent Owner argues that these phrases are not means-plus-function limitations and that “[e]ach claimed ‘current selection module’ is simply a circuit or collection of circuit[r]y that selects current, with additional structural limitations provided by the surrounding claim language.” PO Resp. 17–21. Patent Owner, however, also states that “[t]he Board need not construe the ‘current selection module’ terms because analysis of the prior art does not turn on claim construction.” PO Resp. 18. Patent Owner states it “is not disputing that the prior art discloses ‘current selection modules,’ per se, regardless of which claim construction the Board adopts”; rather, Patent Owner contends “that the current selection modules in the prior art fail to satisfy other claim requirements.” PO Resp. 18. Because there is no dispute between the parties the resolution of which turns on whether the “current selection module” phrases of claims 1 and 12 invoke § 112 ¶ 6, we need not resolve this issue to decide the patentability challenges before us.

    “for the combination and that “Petitioner cites no disclosure from any of the references or background materials suggesting that the cited current supplies were known, interchangeable alternatives.” PO Resp. 60–61. We disagree. As discussed above, Shumarayev discloses separate and independent programmable current supplies for the main driver and the pre-emphasis driver. Ex. 1007, 6:10–17, 6:24–27, Fig. 6. This is an alternative to Groen’s disclosure of separately controlled current select modules (DACs 400 and 402) where DAC 402’s input reference current is the current that is output from DAC 400. Ex. 1004, 5:4–8, Fig. 4. Patent Owner also argues that making a control circuit programmable is more complex than making a non-programmable circuit because “a designer would need to add means to store what is programmed, thus involving more than simple PMOS and NMOS transistors” and requiring additional fabrication steps. PO Resp. 62–63 (citing Ex. 2001 ¶ 70). Both Groen and Shumarayev, however, disclose programmable current sources for pre-emphasis and drive circuitry. Groen’s DAC 400 produces a reference current based on a 5-bit code, and Groen’s DAC 402 produces an emphasis current based on a 3-bit code. Ex. 1004, 4:51–58, Fig. 4. Shumarayev’s driver 44a includes programmable current supplies 56a and 56b, and pre-emphasis driver 44b includes current supplies 58a and 58b that produce an “amount of current that . . . may be controlled by programming how Petitioner’s reliance on Shumarayev’s teachings of separate and independent current sources for main and pre-emphasis drivers introduces any complexity due to the need to make the current sources programmable. Patent Owner also points to Shumarayev’s statement that “there may be consequences of providing too much programmable circuitry” (Ex. 1007, 8:3–4) as suggesting that a person of ordinary skill in the art would not have had a reasonable expectation of success in combining Shumarayev’s teachings with Groen and Gauthier. PO Resp. 64 (quoting Ex. 1007, 8:3–4). According to Patent Owner, Shumarayev’s statement “suggests that the inventors of the ’132 patent, who were able to build successful circuits with independently programmable primary and pre-emphasis current levels, had to overcome various design challenges.” PO Resp. 64 (citing Ex. 2001 ¶ 72). We disagree with Patent Owner’s arguments. Groen discloses programmability to address “a need in the art for a driver circuit that can select from numerous possible data communication operating modes.” Ex. 1004, 1:32–38. The whole purpose of Groen is to accommodate different driver modes by controlling the drive and emphasis currents. Ex. 1004, 3:50–59 (Table 1), 4:1–13 (Table 2), 5:55–67. Shumarayev, similarly, teaches programmable circuitry to accommodate different “I/O standards such as LVPECL, LVDS, PCML, etc.” Ex. 1007, 6:20–23, 7:57–67. Shumarayev then teaches a simplifying alternative, namely, “replac[ing] some or all of the programmable circuitry in I/O circuits 16 with hardwired circuitry.” Ex. 1007, 8:4–7. Thus, we hardly see why a person of ordinary skill in the art would be discouraged from the combination by the alleged complexities of programmability when both Groen and Shumarayev are expressly directed to such programmability.” slip op. at 32

Exhibit A of the Rosenberg declaration contains two archived versions, dated September 3, 2000 and October 23, 2000, of the webpage www.quicklogic.com/devices/QuickFC/Default.html. Ex. 1019, Ex. A. The “second page” of the archived webpage contains a link entitled “QuickFC Device DataSheet.” Id. However, as Patent Owner correctly argues, “the Rosenberg Affidavit only purports to ‘attest[] to the authenticity of the archived and dated QuickFC webpages’—not the purportedly linked to [QL80FC] exhibits” and “[t]he Rosenberg Affidavit neither references QL80FC nor makes any assertion of a connection between QL80FC and the webpages shown in the printouts.” PO Resp. 53–54. Petitioner offers no testimony from a custodian of records for the QL80FC product, as they did for the ORT8850 product, to support a finding that Exhibit 1008 is what Petitioner purports it to be. See Fed.R.Evid. 901(a). Moreover, we disagree with Petitioner’s contentions that FREs 703, 901(b)(4) or 902(7) authenticate or provide a basis to forego excluding Exhibit 1008. FRE 703 allows an expert to base his or her opinion on facts or data an expert in the field would reasonably rely on, even if they are not themselves admissible. Id. 703. They do not prohibit the exclusion of inadmissible evidence or allow for the admission of otherwise excludable evidence. Although FRE 901(b)(4) does allow evidence to be admitted based on its “appearance, contents, substance, internal patterns, or other distinctive characteristics,” Petitioner has not shown that Exhibit 1008 contains sufficient distinctive characteristics to authenticate it. The only characteristic of Exhibit 1008 that tends to show that it is a QuickLogic datasheet for the QL80FC product is the appearance of QuickLogic’s name and logo on the datasheet. See Ex, 1008. But Petitioner fails to present authenticated versions of other QuickLogic data sheets to demonstrate how the structure, format, and appearance of QL80FC is consistent with their structure, format, and appearance. See Pet. Reply 22–23; Opp. 14–15. Finally, FRE 902(7) does not authenticate Exhibit 1008, it only authenticates any “inscription[s], sign[s], tag[s], or label[s]” affixed to Exhibit 1008.

    “maintain our preliminary construction that the plain and ordinary meaning of the transceiver component limitation requires the LOS detector to be “a transceiver component having selectable values that is configured by the plurality of configuration memory cells.” The limitation requires “a plurality of transceivers containing respective components having selectable values,” wherein “said components [are] configured by . . . memory cells,” and wherein “one of said components is a loss of synchronization detector.” Ex. 1001, 6:32–36 (emphases added). Thus, the LOS detector is one of the transceiver components referred to earlier, i.e., one of “said components” “having selectable values” that is “configured by . . . memory cells.” Id. The Specification is consistent with this interpretation. It discloses a transceiver whose receiver side includes deserializer/comma detector 174, decoder 178, elastic buffer 182, CRC 186, and LOS 188.10 Id., Fig. 3. Each of these components is described as being configurable and having selectable values. Id. at 4:54–6:7. Moreover, our interpretation does not render superfluous the use of the term “configurable” in other limitations. To the contrary, the transceiver components limitation only requires transceiver components identified as “one of said components,” i.e., as one of the “respective components having selectable values” to be configurable. It does not require every transceiver component to be configurable because not every transceiver component has to be identified as “one of said components.” Thus, because the serializer and deserializer are not identified as “one of said components” in the “transceiver components” limitation, that limitation does not require that they be configurable. As a result, the claim’s later requirement of “a configurable serializer” and “a configurable deserializer” is not superfluous.” slip op. at 27
