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

    “We disagree with Patent Owner that a person of ordinary skill in the art would have understood that limitation 1.2 must be performed before limitations 1.3 or 1.4. See Ex. 1001, 35:21–24. See Interactive Gift Exp., Inc. v. Compuserve Inc., 256 F.3d 1323, 1342 (Fed. Cir. 2001) (“Unless the steps of a method actually recite an order, the steps are not ordinarily construed to require one.” (citing Loral Fairchild Corp. v. Sony Corp., 181 F.3d 1313, 1322 (Fed. Cir. 1999)). The evidence suggests that a “target printer” is any printer that is ultimately selected for fabricating the object, and such a printer could send its configuration information either before or after that determination is made in limitation 1.2. This interpretation does not render the word “target” meaningless. At some point, a printer must be determined to be the target printer, which is the one intended to ultimately fabricate the three-dimensional object. But the target printer still exists, and is capable of being queried, before that determination is made. We find the examples in the ’774 patent pertinent to this question. The ’774 patent states that “the target printer may include more than one printer.” Ex. 1001, 18:66–67. In discussing the step of “query target printer for properties 306” (Fig. 3A), the ’774 patent states that “[i]n one aspect, numerous queries are sent to numerous printers, e.g., for use in selecting one or more of the printers as the target printer.” Id. at 19:8–10. Alternatively, “the query is sent to a printer that is not necessarily the target printer as described herein, e.g., when the query or information received from a response to the query is used for the selection of the target printer.” Id. at 19:11–14. Importantly, the second embodiment states that the queried printer “is not necessarily the target printer,” suggesting that the queried printer could be the target printer even before it is determined to be such. Id. at 19:11–12 (emphasis added). Based on the evidence of record, a person of ordinary skill in the art would have understood that the “target printer” can be determined after the query recited in limitation 1.3 or the reception of configuration information recited in limitation 1.4. Thus, the evidence does not impose an ordering between limitations 1.2 and 1.3 or between limitations 1.2 and 1.4. The evidence also does not support Patent Owner’s argument that the two reverse-order examples in the ’774 patent are unclaimed embodiments.” slip op. at 10

Looking first to the claim language itself, the word “directly” appears in claims 1, 6, and 10, but not claim 14, presumptively suggesting that claim 14 was intended to more broadly capture systems with either direct or indirect transitions.

The plain meaning of “first type” and “second type” indicates that the first type and second type are different in kind. RMTA 22 (App. A). Our interpretation is consistent with the Specification, which explains that second type SIBs exclude first type SIBs. As Patent Owner points out, the ’958 patent discloses “first type of system information (1TYP SIB) is . . . essential . . . for initial system access” and “second type of system information (2TYP SIB) is nonessential system information . . . defined as all other types of information, and thus excludes the [] information required for initial access.” Id. at 11–12 (citing Ex. 1001, 8:34– 46); see also Ex. 1001, Abstract (interchangeably using the terms second type and non-essential).

Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13.

Aside from the above concerns, we also do not see sufficient explanation with respect to limitation 7h’s requirement that the transmitting by broadcast be based on a comparison of the value tag. Petitioner argues that, because Patent Owner does not dispute limitation 7g, “it would have been obvious to a POSITA to use the same value tag[] to determine the system information broadcast in Lee’s compressed format embodiment.” Pet.

Moreover, whether it was obvious to determine what system information is broadcast is not commensurate with the claim scope because limitation 7h requires that the broadcasting (not the broadcast content) be based on a comparison of the value tag.

We also determine that whether Wright, itself, teaches a mapping step is not the determining factor because Petitioner relies on Baker, not Wright, for teaching mapping limitation 1.4. Nevertheless, Wright does teach allocating bandwidth using the same information that would be available as a result of Baker’s mapping, including the logical (“restricted”) topology and the physical links associated with that topology. In particular, we agree with Petitioner that a person of ordinary skill in the art would have understood that allocating bandwidth to the physical links (step 510 of Figure 5) requires knowing which physical links correspond to Wright’s restricted topology. See Pet. 36; Pet. Reply 22–23; Ex. 1007 ¶ 17; Ex. 1003 ¶¶ 94–96; Ex. 1036 ¶¶ 49–51. We also disagree with Patent Owner that Petitioner has failed to adequately explain how a person of ordinary skill in the art would have modified Baker’s method to apply Wright’s teachings on bandwidth allocation, such as how Baker’s head node N0 would have been modified. See PO Resp. 31–32. Based on the level of ordinary skill and the level of detail in Baker, Wright, and the ’431 patent, and crediting Dr. Houh’s testimony, we find Petitioner’s argument persuasive that such modification would have been within the capability of someone of ordinary skill in the art. See Pet. 17–20 (citing Ex. 1003 ¶¶ 42–46, 48). And we agree with Petitioner that modifying Baker with Wright’s teachings would have been “nothing more than the combination of known elements . . . according to known methods . . . to yield predictable results.” Pet. 20 (citing Ex. 1003 ¶ 47).” slip op. at 32

    “We agree with Patent Owner. Petitioner has not shown that any of the integrated circuits cited in the Petition would have been able to include the claimed acoustic model memory. Further, we find, contrary to Petitioner’s contention, that Patent Owner did not admit that procuring a processor and a memory capable of storing an acoustic model memory fabricated on an integrated circuit was within the level of ordinary skill. To the contrary, throughout the entire proceeding, Patent Owner has consistently argued that the claimed “calculating apparatus and the acoustic model memory are fabricated on a single integrated circuit” was unknown in the prior art. Petitioner has not shown that using the prior art elements relied on in the Petition according to their established functions would have resulted in “the calculating apparatus and the acoustic model memory are fabricated on a single integrated circuit” as recited in claim 1. In summary, Petitioner relies on Mozer to teach the benefits of fabricating a calculating apparatus and an acoustic model memory on the same integrated circuit, but Mozer does not teach a calculating apparatus and an acoustic model memory fabricated on the same integrated circuit. Further, the benefits of Mozer identified by Petitioner are benefits that both Mozer and Smyth already have, without fabricating the calculating apparatus and the acoustic model memory on the same integrated circuit. Also, even if Petitioner had shown there was a reason to combine Smyth and Mozer, Petitioner does not persuasively show that the combination teaches “the calculating apparatus and the acoustic model memory are fabricated on a single integrated circuit” as recited in claim 1.

The Petition did not use the past tense phrase “were already fabricated” as alleged in the Reply. Moreover, the Petition did not map Smyth’s state memory (which the Petition contends teaches the claimed “acoustic model memory” (see Pet. 11)) to a memory already fabricated on an integrated circuit in the prior art. Rather, the Petition relied on Mozer to support its contention that a person of ordinary skill would have fabricated the calculating apparatus and acoustic model memory of Smyth on an integrated circuit. See Pet. 42, 44.

(citing Twitter IPR, Ex. 2013 ¶ 168; Twitter IPR, Ex. 1004, 54). Patent Owner further contends that “Twitter’s conclusory, hindsight-driven statements” do not suffice and PALLAS teaches away from the modifications suggested by Twitter. Id. at 42–43 (citing Twitter IPR, Ex. 2013 ¶ 144). Patent Owner argues that because a learner may not have time to complete a test, a person of ordinary skill in the art would not be motivated to change PALLAS to trigger exercises/tests/quizzes based on location or time. Id. at 43 (citing Twitter IPR, Ex. 2013 ¶¶ 142–144). The evidence of record does not support Patent Owner’s arguments.” slip op. at 115

    “2. Enlarging Scope of Claims Patent Owner asserts that it proposes narrowing limitations in direct response to the grounds of unpatentability involved in this proceeding. See, e.g., Snap Mot. 3–4. Facebook argues Patent Owner is “improperly attempting to enlarge the scope of the original claims.” Facebook Pet. Opp. 1. Facebook asserts, “[i]f ‘an expected response’ means one or more expected responses, therefore, determining whether the received response ‘matches the expected response’ means that the received response must match [all of] the one or more previously-recited expected responses in the content package.” Id. at 3 (emphasis omitted). Facebook then argues “the term ‘predefined response’ is broader than ‘expected response,’” because “an ‘expected response’ does not include any conceivable or possible response; it is a response that is expected.” Id. at 4–5 (emphasis omitted). Twitter argues that “‘predefined response’ is broader than ‘expected response’ because a ‘predefined response’ can include any possible response as long as that response has been somehow defined in advance.” Twitter Pet. Opp. 2. We consider the amendments in view of the claim as a whole. Although the term “one predefined response” may be broader than “an expected response,” we also consider the amended portion “wherein the received response is expected if the received response matches one or more of the at least one predefined response,” and “the received response is unexpected if the received response does not match any of the at least one predefined response.” Unless the response had been predefined within the content package, any “received response” could not be considered “expected” under the claims, and the additional clause requires a match of the response with the predefined response to be deemed “expected.” This equates to an equivalent scope to the original claim. This is consistent with Dr. Martin’s testimony, which we credit, that he is not aware of a situation where the substitute but not original claims are infringed because “[t]he substitute claims would only be satisfied when a ‘predefined response’ in the substitute claims is an ‘expected response’ in the original claims.” Facebook IPR, Ex. 2023 ¶ 59.” slip op. at 136
