    “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

As discussed above, the parties agree that the preamble of claim 1, including the “service auto-configuration method” language, is limiting. See § II.B, supra.

The evidence of record, including the ’892 patent and its prosecution history,9 indicates that the ordinary and customary meaning of “transitioning . . . from . . . to” encompasses both direct and indirect transitions. 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.

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 that Petitioner has not shown, by a preponderance of evidence, that state memory 342 of Smyth is fabricated on the same integrated circuit as processor 341. Petitioner, in asserting that processor 341 and state memory 342 are on the same integrated circuit, cites the following testimony of Mr. Schmandt: In my opinion, the Motorola DSP56000 provides both memory and a processor fabricated on a single integrated circuit (IC). Kloker (Ex. 1009), 1 (discussing the Motorola DSP56000 includes “a core processor, RAM, ROM, peripheral interfaces, and a memory expansion interface on a single, 88-pin chip[”)]. . . . A POSITA would have understood or at least found obvious that Smyth thus teaches a single IC on which both classifier processor 341 and state memory 342 are fabricated. Ex. 1003 ¶ 165; Pet. 39. We do not credit Mr. Schmandt’s testimony because it is inconsistent with Smyth’s disclosure. Smyth discloses that classifier 34 comprises classifying processor 341 and state memory 342, and that “classifying processor 341 may be a suitably programmed digital signal processing (DSP) device.” Ex. 1005, 5:55–57, 6:5–6. Thus, Smyth itself, in discussing classifier 34, distinguishes processor 341 from state memory 342 in stating that only processor 341, and not both processor 341 and state memory 342, may be located on the DSP. describe processor 341 and state memory 342 as being fabricated on a single integrated circuit. Ex. 2020 ¶¶ 34–37.

    “In our Decision to Institute, we understood Petitioner’s theory based on the combination of Smyth and Mozer to include fabricating an integrated circuit in stating that we were sufficiently persuaded “that fabricating a single integrated circuit that includes a calculating apparatus and an acoustic model memory . . . was within the level of ordinary skill.” Dec. 23. Our understanding was based on the Petition’s multiple contentions that a person of ordinary skill would have found it obvious to fabricate Smyth’s processor and state memory on a single integrated circuit. See Pet. 41–44. For example, the Petition contends that “[a] POSITA would have found it obvious . . . to fabricate [Smyth’s processor and state memory] on a single integrated circuit” (Pet. 41–42 (emphasis added)); “a POSITA would have understood and found obvious . . . to fabricate a calculating apparatus and acoustic model memory on a single integrated circuit” (Pet. 42 (emphasis added)); “[s]uch a use of a known technique of fabricating a memory and processor on a single integrated circuit” (id.

Reply 22–25. According to Petitioner, “the Petition did not map a POSITA physically fabricating an IC, but rather mapped a POSITA modifying Smyth according to Mozer’s undisputed teachings of a single IC on which a calculating apparatus and acoustic model memory were already fabricated.” Id. at 23–24. However, as discussed in the previous paragraph, when discussing the combination of a processor and an acoustic model memory on an integrated circuit, the Petition used the verb “to fabricate” four times in the future tense and once in the present tense, as well as the verb “to form” once in the future tense. 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. The Petition cited Boike and Ozcelik in contending that fabricating an integrated circuit with processors and memories was well known, and cited Toyoda in contending that fabricating an integrated circuit with a calculating apparatus and an acoustic model memory was well known. Pet. 43–44 (citing Ex. 1006; Ex. 1029; Ex. 1034). However, the Petition did not explain how a memory located in one of the integrated circuits of Mozer, Boike, Ozcelik, or Toyoda would have been able to store Smyth’s state memory. Therefore, we disagree with Petitioner’s contention that “the Petition did not map a POSITA physically fabricating an IC, but rather mapped a single IC on which a calculating apparatus and acoustic model memory were already fabricated.” Reply 23–24. We find that this contention was untimely presented in the Reply. We do not permit Petitioner to propose a mapping of the prior art in the Petition and then completely change that mapping after Patent Owner argues the initial mapping was flawed.

PO Resp. 9–10; see also Ex. 2001 ¶ 37 (Patent Owner’s declarant, Dr. Stone, accepting and applying Petitioner’s proposed level of ordinary skill). In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

    “then save.” PO Resp. 10 (citing Ex. 2001 ¶¶ 48–56). According to Patent Owner, “[m]erely saving data is not enough.” Id. Petitioner disagrees, contending that Patent Owner’s proffered interpretation of “record” is inconsistent with the Specification, which “repeatedly distinguishes between ‘record’ and ‘measure’” and uses “‘record’ in connection with saving/storing and ‘measure’ in connection with sensing.” Reply 2–3 (citing Ex. 1001, 2:28–34, 8:51–53, 11:61–62, 11:65–67, 13:5–6, 15:18–24, 15:41–45, 20:2– 6; Ex. 1017 ¶¶ 13–19). Based on our review of the parties’ argument and cited evidence, we find that “record” means “save” and does not encompass “measure or capture” as Patent Owner argues. The Specification describes the act of measuring as being performed by various sensors or other devices. See, e.g., Ex. 1001, 8:51–53 (“sensors for measuring”), 11:65–67 (“accelerometers . . . for measuring”), 15:18–24 (“Global Positioning Satellite (GPS) navigation device” for measuring distance traveled and an “EKG monitor” for “measuring the electrical activity of the user”). The Specification also expressly distinguishes the act of measuring from the act of recording when discussing how the location of a user is measured and recorded. The Specification states: The inclusion of GPS device 713 and accelerometer 715 in a single mobile device 700 allows device 700 to record athletic activity data in multiple workout settings. . . . If, . . . the individual is running outdoors such that the individual moves from one location to another, the GPS device 713 or recording of data therefrom (e.g., GPS device is always active, but recording is turned on and off) may be activated and used instead [of the data measured by accelerometer 715]. Id. at 19:59–20:6 (emphasis added). Even though GPS “is always active” and measuring the location of the user, “recording is turned on and off.” Accordingly, the Specification expressly distinguishes that act of measuring from the act of recording.” slip op. at 11

And, regardless of the exact wording, the concern we have is that without a persuasive, express, indication in the specification that the “second function” is specifically limited to “predicting glucose values,” it is a disfavored path to read limitations into the claims.
