    • 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

      “We disagree that Petitioner’s arguments are based on impermissible hindsight, because they are based on the disclosures in Douglas and Mark, and Petitioner has articulated a persuasive reason to combine those references without referring to the ’774 patent itself, as we discuss below. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (an obvious rationale is not improper hindsight if it “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”).” slip op. at 29

      “Level of Ordinary Skill in the Art Citing testimony from Dr. Houh, Petitioner contends a person of ordinary skill in the art “would have had at least a B.S. degree in computer science or electrical engineering (or comparable degree) and two years of experience in networking or streaming media, or a M.S. in computer science or electrical engineering (or comparable degree).” Pet. 12 (citing Ex. 1003 ¶ 45). Patent Owner does not address the level of ordinary skill in the art in its post-institution papers. We adopt Petitioner’s definition of the level of ordinary skill in the art.

      “On this record, we determine that the recitation “to achieve continuous presentation” is limiting and requires an amount of continuous (uninterrupted) playback/presentation after an upshift or downshift. The specification describes agent controller 702 determining whether to upshift based on a trigger threshold Θup, which itself is based on various factors including a current read ahead margin and a minimum safety margin. See Ex. 1001, 17:44–58. If agent controller 702 can sustain upshift quality, then it will upshift and request higher quality streams. See id. at 17:58–61. Conversely, when an upshift is not possible, agent controller 702 determines whether to downshift based a different threshold Θdown, which itself is based on the same sort of factors. See id. at 18:4–7. When the stream quality is not adequate, it downshifts. See id. at 18:7–14. These disclosures are similar to the language of claim 12, which recites “repeatedly generating a factor indicative of a current ability to receive the digital content at a rate sufficient for presenting the digital content as the digital content is received, . . . wherein the factor relates to a performance of the network” and “making the successive determinations whether to change the requested bit rate based on the factor to achieve continuous presentation of the digital content using the individually-requestable portions of the highest bit rate one of the copies determined receivable at that time.” Ex. 1001, 20:5–16 (emphasis added). That is, claim 12 refers to “achiev[ing] continuous presentation” based on what is “sufficient for presenting the digital content,” trading quality to ensure continuous playback.” slip op. at 14

      “server comprises at least two servers and wherein at least one streamlet is requested from a first of the at least one server and at least one other streamlet is requested from a second server of the at least one server other than the first server.” Ex. 1001, 19:7–12. Petitioner references its mapping of the “at least one server” in claim 1 to Leaning’s server 1. Pet. 20 (citing Ex. 1004, 2:15–16, 2:18–22, 2:31–32, 5:8–14, Fig. 1), 23 (citing Ex. 1004, 6:13–26, 9:3–7, 16:6–12), 37; see supra §§ II.D.2.b–c. Petitioner contends that, “[t]o the extent Leaning does not disclose at least two servers wherein one sub-file (streamlet) is requested from a first server and another sub-file (streamlet) is requested from a second server such an arrangement would have been obvious in view of the knowledge of a [an ordinarily skilled artisan].” Id. at 37. Citing the common nature of such an arrangement, Petitioner contends that an ordinarily skilled artisan would have been motivated to provide multiple web servers containing the same sets of sub-files for streams in order to have redundancy in the system and allow for clients to establish connections with multiple servers and request a first sub-file from a first web server and, if the connection between the first web server becomes congested or the first web server otherwise fails or becomes unavailable, request a subsequent sub-file from the second web server. Id. at 37–38 (citing Ex. 1003 ¶ 85; Ex. 1012, 108,5 Fig. 4-11). Patent Owner does not dispute Petitioner’s analysis for claim 3. We are persuaded that it would have been obvious to implement Leaning’s server 1 as two servers that store different streamlets based on Dr. Houh’s uncontested testimony about system redundancy. See Ex. 1003 ¶ 85. His testimony is backed by a contemporaneous reference about HTTP that shows requests for different objects from different servers over parallel TCP connections. See, e.g., Ex. 1012, 108–09, Fig. 4-11. Thus, we determine that Petitioner has shown, by a preponderance of the evidence, that the subject matter of claim 3 would have been obvious over Leaning.” slip op. at 34

      “specification is the ‘single best guide to the meaning of a disputed term,’ . . . and ‘is, thus, the primary basis for construing the claims.’” Trs. of Columbia Univ. in City of New York v. Symantec Corp., 811 F.3d 1359, 1362 (Fed. Cir. 2016) (citations omitted). Although Patent Owner contends that the Specification disparages systems that impose significant restrictions on the possible choices of frequencies (PO Resp. 21), we find availing Petitioner’s contention that “[s]upport for Patent Owner’s construction is absent from the specification.” Pet. Reply 10. As Petitioner points out, Patent Owner’s claim construction “appears to be based on a single paragraph of the ’443 patent referring to preexisting ‘synchronization schemes [that] restrict the phase relationship and relative frequencies of the clocks.” Id. That is, the only reference by Patent Owner to the Specification is that the Specification states that “Some synchronization schemes restrict the . . . relative frequencies of the clocks, thereby eliminating the need for hardware arbitration [27]. Unfortunately, these schemes impose significant restrictions on the possible choices of frequences.” PO Resp. 26 (citing Ex. 1001, 6:32–36). We agree with Petitioner that such disclosure in the Specification “does not describe how these synchronization schemes ‘restrict the phase relationship and relative frequencies’ with any specificity.’” Pet. the Specification that some schemes impose restrictions on the possible choices of frequency is not a disparagement of any system that has limited choices of frequency or would preclude the claims from covering such prior art techniques. Instead, as Petitioner points out, the Specification of the ’443 patent states “[t]he preferred embodiment uses four domains […] so that domains may vary somewhat in size and still be covered by a single clock.” Id. (citing Ex. 1001, 5:57–59). As Dr. Baker testified in support of Petitioner’s contention, “the preferred embodiment of the ’443 patent relies on a single external master clock that distributes a signal to the local PLL of each domain.” See Ex. 1032 ¶ 9. Thus, although Patent Owner contends that clock signals generated based on a master clock cannot be interpreted to be generated independently of the clock signals generated for others of the plurality of domains (PO Resp. 49), we agree with Petitioner that such claim construction would “exclude[] the preferred embodiment of the ’443 patent,” which is disfavored. Pet. Reply 11. For the reasons discussed above, we conclude that “changeable independently” of the other domains does not require that the separate clocks in the plurality of domains be globally-asynchronous.” slip op. at 12

      “As both parties recognize, (PO Resp. 5; Pet. Reply 12), “[actual] [r]eduction to practice in the United States requires that the invention be embodied in tangible form.” Scott v. Koyama, 281 F.3d 1243, 1247 (Fed. Cir. 2002). In particular, actual reduction to practice requires a showing of the invention in a physical or tangible form that shows every element. not sufficient. See Kimberly-Clark v. Johnson & Johnson, 745 F.2d 1437, 1445 (Fed. Cir. 1984). Here, Patent Owner does not provide any evidence showing every element of the claims in physical or tangible form, as required, but rather contends that the Specification refers to the Paper, wherein the Paper stated that simulation using a software, SimpleScalar, was performed. PO Resp. 16. We are persuaded by Petitioner’s contention that the SimpleScalar simulation was not an actual reduction to practice of the claimed invention. Pet. Reply 12. As Petitioner points out, claim 1, for example, is directed to a “microprocessor,” wherein “Patent Owner has presented no evidence and has not alleged that any physical microprocessor was ever produced or operated.” Id. at 13; see PO Resp. 15–17. And as Petitioner points out, “Patent Owner has produced no evidence of any physical prototype of the claimed microprocessor that could have validated the simulation.” Pet. Reply 13–14. We agree with Petitioner that, at most, such simulation “demonstrated feasibility for prototyping of a microprocessor,” but not a tangible form of the microprocessor itself as required for an actual reduction to practice. Id. at 14; see also Standard Mfg. Co. v. United States, 25 Cl. Ct. 1, 67 (1991) (“The feasibility of the optical alignment system may have been proven by the optical mock-up, but the optical mock-up was not a reduction to practice of the proposed MHU–145/M trailer.”).” slip op. at 36

      “Here, we find that Petitioner has not met its burden to prove that one of ordinary skill in the art would have recognized that “the functional units of Georgiou operate asynchronously since they have different clocks.” Pet. 74 (citing Ex. 1002 ¶¶ 53–56, 211–219). Specifically, although Petitioner relies on Georgiou for teaching different clocks, Petitioner’s conclusory statement that such application would operate asynchronously requires gapfilling. Id. As Patent Owner points out, Georgiou discloses a clocking architecture in which “all domain clocks are derived from a shared master clock through predetermined rational dividers.” PO Resp. 49. Petitioner concedes during the oral hearing that, in systems such as Georgiou, each domain clock is set a fraction of a master clock, and thus, the various domain clocks are “possibly” synchronous with each other. Tr. 59:4–14 (JUDGE DANG: . . . would being fractions of the master, wouldn’t they be synchronized with each other? MR UHR: They may be, . . . the answer is possibly.”) Thus, we find Petitioner’s contention that a POSITA would have recognized that the functional units of Georgiou operate “asynchronously” lacks sufficient support in the record. We find the testimony of Dr. Baker insufficient to support Petitioner’s position. Ex. 1002 ¶¶ 53–56, 213, 215–219. In his declaration, Dr. Baker testified that he “provided several references . . . that explain operating domains asynchronous to one another while the domains operate synchronously.” Id. ¶¶ 215–219. However, although such references explain “globally asynchronous, local synchronous (GALS) systems” (id. ¶ 216), Dr. Baker does not explain why a POSITA “would have known that a functional unit of Georgiou also operates asynchronous with respect to at different frequencies.” Id. ¶ 217. Without evidentiary support, we are left with speculation and impermissible hindsight. See in Re Wagner, 379 F.2d 1011, 1017 (CCPA 1967). We decline to engage in speculation.

      “We do not agree with Patent Owner’s argument that Dr. Almeroth’s declaration testimony contradicts Kleve. See PO Resp. 27–29. 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)). In a particular embodiment to which Dr. Almeroth was citing, he noted that the e-key is always generated after the rental agreement. See Ex. 2022, 26:14– 20. Then the following exchange occurs: Q. 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.

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 question before us, therefore, is whether the Petitioner’s proffered explanation that it has proposed a different claim interpretation before the Board because the District Court may decline to adopt the narrower claim interpretations it advocates there is sufficient. We find that Petitioner’s explanation is sufficient because it follows the Director’s exemplary logic. Whether a district court has already or might in the future decline to adopt constructions that a petitioner proposes in related district court litigation merely reflects the timing of when a dispute over claim interpretation will be resolved. The Director and Patent Owner both recognize that, to resolve the dispute over claim interpretation that exists here, a decision-maker must determine “a single claim construction that best captures the true meaning of the patent claim.” Remand 4; PO Remand Br. 3. Based on the record presented by the parties to date in this proceeding, no dispute exists that the disputed claim terms mean what Patent Owner says they mean in the Litigation. Accordingly, we find that, at this stage of the proceeding, it is undisputed that Patent Owner’s interpretations of the claim terms represent the “single claim construction that best captures the true meaning of the patent claim.”8 Under that claim interpretation, we” slip op. at 8

      “articulated a reason why a person of ordinary skill in the art would have combined the teachings of Sudre, Lee, and Penven. Prelim. Resp. 60–63. In particular, Patent Owner argues that a person of ordinary skill in the art “would not have been motivated to look into Penven to modify the teachings of Lee because Lee and Penven disclose substantially different structures.” Id. at 60–61. This argument does not address Petitioner’s proposed reason to combine, which looks to Lee and Penven each to modify Sudre, not to Penven to modify Lee. See Pet. 79–81. In addition, “[c]ombining the teachings of references does not involve an ability to combine their specific structures.” In re Nievelt, 482 F.2d 965, 968 (CCPA 1973). In other words, “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425–26 (CCPA 1981). Petitioner provides “some articulated reasoning with some rational underpinning” to combine the teachings of Sudre with those of Lee and Penven. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). In particular, Petitioner directs us to Sudre’s teaching of “a method for manufacturing PMC,” to Sudre’s lack of teaching of “specific parameters, such as warp thread size and spacing” to satisfy the “particular requirements” of its fabric.

      “III. CONCLUSION Because we determine that Petitioner has demonstrated a reasonable likelihood that it would prevail in showing at least one of the challenged claims is unpatentable, we institute inter partes review as to all challenged claims and grounds presented in the Petition. At this stage of the proceeding, we have not made a final determination as to the patentability of any of these challenged claims.

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

      “ordinary meaning, “primary” and “non-primary” cells are all cells that the WTRU is connected to (PO Resp. 16), the plain language in claim 1, and similarly in claim 7, does not require a “primary” node or “non-primary” cell to have a connection to the WTRU. See Ex. 1001, 10:38−56; 11:11–26. We find unavailing Patent Owner’s contention that the claims require that the WTRU “be connected to more than one cell,” wherein cells that are “associated with a wireless network node,” but are not connected to the WTRU “at the same time” cannot be “primary” or “non-primary” cells. PO Resp. 16. In the ’803 patent, nothing in the Specification clearly limits “primary” and “non-primary” cells as Patent Owner proposes. Prelim. Resp. 16. Patent Owner points to the Specification of the ’803 patent to show that, for softer handover, the WTRU is connected “with more than one cell [] which are controlled by the same Node-B,” and “[o]ne of the[se] cells 808 may be designated as a primary cell 808a, while other cells are designated as a non-primary cells 808b.” Id. (alterations in original) (citing Ex. 1001, 8:44–46, 9:4–6, Figs. 8A–B). However, this portion of the Specification (describing a softer handover embodiment in which a cell “may be designated” as a primary while other as non-primary) does not provide a clear definition to warrant interpreting the “primary” and “non-primary” cells as requiring “connection” to the WTRU “at the same time.” Id. That is, nothing in the Specification clearly precludes “primary” and “non-primary” cells from being “source” and “target” cell, as Patent Owner contends. PO Resp. 16. and the Specification, we determine that the terms “primary” and “non-primary” recited in claims 1 and 7 are not limited to cells connected to a WRTU at the same time. We determine no further explicit construction of this term is necessary to resolve the controversy. See Vivid Techs., 200 F.3d at 803.” slip op. at 8

      “f) Motivation to combine Ericsson and TS 25.331 Petitioner contends that a “POSITA would have been motivated to combine Ericsson and TS 25.331 because they are directed to similar technologies and a skilled artisan would have understood the benefits of combining these two references,” and “would have understood that there was a high likelihood of success in making the combination.” Pet. 34 (citing Ex. 1003 ¶¶ 156–157). In particular, the references “are both reasonably pertinent to the problem faced by the inventor, namely protocols for handover in a telecommunications system.” Id. (citing Ex. 1003 ¶ 158). According to Petitioner, the combination “involves the predictable use of interchangeable prior art elements according to their established functions” more than routine engineering.” Id. at 37 (citing Ex. 1003 ¶ 174). At this stage of the proceeding, Patent Owner does not present arguments in the Preliminary Response addressing the specific merits of Petitioner’s contentions with respect to the motivation to combine Ericsson and TS 25.331. See generally Prelim. Resp. 15–18. We find availing Petitioner’s contention that Ericsson and TS25.331 are “directed to similar technologies,” and that a “skilled artisan would have understood the benefits of combining these two references.” Pet. 34.

      “connections or multiple, parallel/simultaneous TCP connections are critical, unclaimed features of the ’564 patent. Indeed, Petitioner does not argue as much, and claims 2, 9, and 11 all at least recite multiple TCP connections. Notwithstanding, I would reach the same conclusion as my colleagues that Patent Owner is not entitled to a presumption of nexus. I am persuaded by Petitioner’s argument (Pet. Reply 22–23) that Patent Owner cannot credibly maintain that it is entitled to a presumption of nexus to the same products— the MOVE Media Player and “Sling TV”—across nine patents and 120 claims having different scope while citing to substantially the same alleged evidence of secondary considerations. The MOVE Media Player and “Sling TV” cannot be coextensive with the challenged claims here under these circumstances. In addition, Patent Owner’s own cited evidence suggests that MOVE’s plug-in is a “key” feature of its technology, particularly to ensure “fluidity of playback” (PO Resp. 50 (quoting Ex. 2048) (emphasis omitted)), but the claims do not recite a plug-in. This also undermines Patent Owner’s assertions of coextensiveness for claims that all recite “continuous playback.” Otherwise, I agree with my colleagues’ finding that Patent Owner has not adduced significant evidence of direct nexus. Accordingly, I join in my colleagues’ finding that Patent Owner has failed to establish a nexus between the asserted evidence of secondary considerations and the challenged claims. I also agree that Patent Owner’s evidence of secondary considerations is entitled to insignificant weight, or little to no weight, and that it does not outweigh Petitioner’s persuasive obviousness showing under the other Graham factors.
