  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “II. ANALYSIS A. Level of Ordinary Skill in the Art Relying on the testimony of Dr. Bims, Petitioner proposes that a person of ordinary skill in the art at the time of the ’842 patent would have been a person having a bachelor’s degree in electrical engineering and two years of work experience with network and communication technologies. Pet. 11 (citing Ex. 1001 ¶¶ 15–16). Patent Owner does not provide any proposed qualifications for a person of ordinary skill in the art. 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. Cir. 1995) (citation omitted). The level of ordinary skill in the art is also reflected by the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).

  • Strike new argumentNew argument disregardedDecided for patent owner

    “We agree with Patent Owner. The Petition is required to identify “[h]ow the challenged claim is to be construed.” 37 C.F.R. § 42.104(b)(3). Petitioner argued in the Petition that “as properly construed, the claimed ‘first parameter,’ ‘second parameter,’ ‘third parameter,’ and ‘fourth parameter’ are four different parameters.” Pet. 17–18. In the Institution Decision, Petitioner prevailed on that point and “we agree[d] with Petitioner that the second and third parameters are separate and different parameters, and not different instances of the same parameter for separate channels.” Dec. 14. Patent Owner “relie[d] on the Board’s construction ‘that the second and third parameters are separate and different parameters, and not different instances of the same parameter for separate channels,’” and proposed distinct parameters in the Specification that it alleges are examples of second and third parameters, albeit not the same two parameters proposed by Petitioner. PO Resp. 9, 29. Petitioner now proposes new constructions for the second and third parameters that would limit those parameters to the two examples it advanced in the Petition and improperly supports these new constructions with new expert testimony and an exhibit from the prosecution of a later patent. Reply 20–25; Ex. 1040 ¶¶ 20–29; Ex. 1038. See also Consolidated Trial Practice Guide (“TPG”)10 73 (“Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.”). As Patent Owner observes (Sur-reply 10 Available at https://www.uspto.gov/TrialPracticeGuideConsolidated. 21), it has no opportunity to introduce rebuttal evidence contesting the new constructions. See TPG 73–74 (Nov. 2019) (“The sur-reply may not be accompanied by new evidence other than deposition transcripts of the crossexamination of any reply witness. Sur-replies should only respond to arguments made in reply briefs, comment on reply declaration testimony, or point to cross-examination testimony.”). We agree with Patent Owner that it would be unfair to consider Petitioner’s new construction. See 37 C.F.R. § 42.23(b) (“A reply may only respond to arguments raised in the corresponding opposition, patent owner preliminary response, patent owner response, or decision on institution.”). Thus, Petitioner has forfeited its new claim construction arguments and they will not be considered. See TPG 74 (“While replies and sur-replies can help crystalize issues for decision, a reply or sur-reply that raises a new issue or belatedly presents evidence may not be considered.”). Moreover, these arguments would be unpersuasive even if considered. Petitioner has, at most, cited description in the Specification to show that its identified second and third parameters are examples corresponding to the recited second and third parameters. Ex. 1005 ¶¶ 84–95. This description does not define the second and third parameters nor purport to exclude from the claims any parameter that would otherwise meet the language of the claims. The prosecution history to which Petitioner cites, that of a child application, took place after the prosecution of the ’466 patent and thus, does not constitute a definition or disclaimer of subject matter for claims of the ’466 patent. In any case, the brief argument in the cited response to office action, that “[i]n the algorithm, the first value is provided by the wireless network for each of a plurality of buffers where the buffer having the second value above a threshold transmits data first,” does not define the second and third parameters, disavow any values from those parameters, or even discuss the third parameter. Ex. 1038, 12. Petitioner’s extrinsic evidence, Dr. Akl’s testimony, does little more than repeat the arguments in the Reply and, thus, is of little value. Ex. 1040 ¶¶ 20–29. In sum, we maintain our construction that the second and third parameters are separate and different parameters, and not different instances of the same parameter for separate channels. Under this construction, RAAUq” and RAAUq’, respectively, could potentially be second and third parameters, as could RAAUq’ and RAAUq”, respectively, as long as they satisfy the rest of the pertinent language of the challenged claims.” slip op. at 15

    “production, we still would find that a skilled artisan would not have been able to ascertain from the disclosure in the ’421 application that RAAUq’ could take values less than zero. Instead, even if we were to credit Dr. Lomp’s testimony, to conclude that RAAUq’ can take negative values, a skilled artisan would need to program computer software to simulate the ’421 application’s algorithm and correctly choose starting parameters and other context variables without guidance from the description in the ’421 application. This case is similar to that in New Railhead, where the written description was insufficient because “one of ordinary skill in the art must first make the patented invention before he can ascertain the claimed features of that invention.” 298 F.3d at 1295. This case also is similar to Los Angeles Biomedical Research Institute, in which an application’s written description was insufficient because assumptions and starting variables were not knowable from the disclosure in the application. 849 F.3d at 1058. Thus, even if we were to conclude that Patent Owner has met its burden of production, a preponderance of the evidence shows that the ’421 application does not provide written description support for Alternative A. In sum, we conclude that the ’421 application does not provide written description support for the challenged claims and that, therefore, Speight is prior art to the challenged claims.” slip op. at 41

    “term “placing” requires more than a theoretical placing or planning to place as part of an analytical solution. Turning first to the claim language, we agree with Petitioner that the language of the independent claims is consistent with “placement” occurring after and separately from the analytical evaluation process. See Pet. Reply 3. For example, claim 1 is directed to a system for “determining placement of source computer systems on target systems,” the system configured to “determine a placement” by employing operations to “evaluate compatibility.” Ex. 1001, 40:2–4, 40:8– 36. The second “evaluate compatibility” operation is “to determine if the specific source system can be placed with those other source systems on the specific target system,” which suggests that what is being evaluated is whether the source system can be actually placed (e.g., moved or transferred) to the target system. Id. at 40:18–27 (emphasis added). Similarly, the third “evaluate compatibility” operation involves “evaluating the impact on resource utilization of the specific target system of placing the specific source system on the specific target system,” which suggests that what is being evaluated is the impact on resource utilization once the source system is actually moved or transferred to the target. Id. at 40:28–32 (emphasis added). Additionally, the claim states that, based on the “evaluate” operations, the claimed system “determine[s]” a placement, not that it executes the placement. Id. at 40:8–11. The actual placement seemingly occurs after the final claimed operation of “issu[ing] instructions to place” the source system(s) on to the target system “in accordance with the determined placement.” Id. at 40:37–39. Independent claims 32 and 63 include similar language. Id. at 42:36–43:3, 45:1–46:19. Had the patent applicant wanted to cover systems that were merely “hypothetically placed,” language to that effect could have been added to the claim.” slip op. at 19

  • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateUnpatentable

    “As noted above, the claim language requires evaluating compatibility between a specific source system and one or more other source systems “already placed” on the target system. Paragraph 82 does not disclose the evaluation of compatibility of a source system and another source system as part of the “forward consolidation.” Additionally, paragraph 82 does not disclose that “existing target systems 16” have source systems “already placed” on them. Thus, paragraph 82 does not provide the level of detail recited in the limitation under either party’s definition of “placed.” In addition, as noted above, we have interpreted “placed” to require an actual placement rather than merely “planning to place” or a theoretical placement. See § II.A.2, supra. Therefore, even if the “existing target system 16” had theoretical or hypothetical systems added to it as part of the consolidation analysis, those would not be systems that are “already placed” on the target system.” slip op. at 34

Specifically, Petitioner does not allege an incorrect statement in Patent Owner’s contention that “Petitioner admits that JP029 discloses performing the encoding on all bits of binary data, including the ‘first bit’ of data.” Prelim. Resp. 55 (citing Pet. 29). Nor does Petitioner allege an incorrect statement in Patent Owner’s contention that “Petitioner’s expert opines – with no explanation or citation – that the claims require ‘separately arithmetically encoding/decoding a first bit of binary data using a separate probability table from the probability table (or tables) used to encode/decode the remaining bits of binary data.’ Nothing in the claims require this.” Id. at 57 (citing Ex. 1003 ¶ 52). Instead, Petitioner, for the first time in its Reply, proposes construing the claim beyond its plain and ordinary meaning in order to rebut Patent Owner’s contention that the plain and ordinary meaning of the claim does not require coding a first bit separately from the remaining bits, using separate probability tables. Petitioner has not explained how Patent Owner made an incorrect statement, nor has Petitioner explained why Patent Owner’s construction of the claim based on the claim’s plain and ordinary meaning was unanticipated. See Pet. 7 (“[T]he Petition does not present any controversy over claim meaning and the Board need not construe any terms.”); see id. at 8 (“Petitioner maintains that the Challenged Claims would have been obvious under any reasonable construction.”). Petitioner’s new claim construction alleging prosecution history disclaimer, and Petitioner’s corresponding new argument based on the alleged disclaimer, are untimely.” slip op. at 24

Patent Owner’s declarant, Mr. Michael Adams, provides similar assessment, but also testifies that such an artisan, alternatively, would have had “at least five years of work experience and training in the design and development of distributed network systems and/or multimedia streaming.” Ex. 2012 ¶ 28.

    “added). Dr. Houh testifies that an ordinarily skilled artisan would have used Wiser’s voucher ID in Eyal’s play-list because delivery servers may have a “limited number of active streams of data being delivered at any one time,” so that generating and tracking reservations by the content server using voucher IDs is necessary. Ex. 1003 ¶ 144 (citing Ex. 1006, 14:65−15:1). We agree with and credit Dr. Houh’s testimony, and we find that such an artisan of ordinary skill would have understood that, in Eyal in combination with Wiser, the voucher ID provided in the play-list is uniquely associated with the client device and a viewing session of the media. Ex. 1003 ¶ 151 (citing Ex. 1006, 8:30−33, 15:23−28). We do not agree with Patent Owner’s assertion that “Wiser teaches away from video.” PO Resp. 33 (citing Ex. 2012 ¶ 174). “A reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). Here, nothing in Wiser would discourage a relevant artisan from applying its teachings to video media, as Patent Owner alleges. Patent Owner’s argument of teaching away is based on speculation. As discussed above, Wiser’s disclosure is not limited to audio media. Ex. 1006, 1:5−8, 1:23−26, 3:8−10; Ex. 1083, 145:20−147:21. The “mere disclosure of alternative designs does not teach away.” In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Moreover, KSR instructs us that “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize 20 that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. As Dr. Houh testifies, “[s]ervers’ limited streaming capacity was a common media delivery problem, and well-known solutions existed before the ’360 Patent, including generating a reservation to ensure resource availability for streaming media to the user.” Ex. 1003 ¶¶ 106, 167 (citing Ex. 1019, 263 (Discussion on Resource Reservation Protocols (RSVP) in the book entitled “Communication and Computing for Distributed Multimedia Systems”); Ex. 1023 (RSVP Specification); Ex. 1024, 194 (Discussion on the Reservation Protocol in the book entitled “Multimedia Servers”)).” slip op. at 20

We do not agree with Patent Owner’s argument, that just because Eyal’s system “works perfectly well,” a person of ordinary skill would not seek to improve its performance. We rely, instead, on Dr. Houh’s testimony, summarized above, that there would be advantages in combining the teachings of Eyal and ASF Files. Houh Decl. ¶¶ 140–141. For example, as discussed supra, Dr. Houh testifies that a person of ordinary skill would have been motivated to modify Eyal to utilize the ASX files “to improve the ability of its play-lists to work effectively with Windows Media Player end user terminals.” 23 Id. ¶ 140. Further, we credit his testimony that a person of ordinary skill would have been motivated to combine Eyal’s disclosure with ASX Files to improve advertising features disclosed in Eyal. Id. at 141. He testifies that a person of ordinary skill would have had “a reasonable chance of success” because the ASX file format is XML, “a common format for data exchange on a network.” Id. ¶ 142. In contrast, Mr. Adams testifies that “there is no motivation to add the use of ASX files to Eyal.” Adams Decl. ¶ 139. Mr. Adams supports this testimony by asserting that “the Eyal system builds a simple play list and nothing more.” Id. We disagree with this assertion by Mr. Adams and with the implication that follows, that because the Eyal system is “simple,” a person of ordinary skill would not seek to improve it. See discussion of Dr. Houh’s testimony, supra. We are also not persuaded by Mr. Adams’s testimony that Eyal’s disclosure of Windows Media Player is “not in [and] of itself” a reason to consider using ASX files in Eyal, “when Eyal works perfectly well without it.” Adams Decl. ¶ 141. This testimony is unavailing for several reasons. First, the evidence of record links Windows Media Player with use of ASX Files. See Ex. 1017, 1 (“ASX files are simply text files that act as links from Web pages to ASF files on Windows Media Services or HTTP servers.”). Also, Mr. Adams’s testimony assumes (incorrectly) that because Eyal may work with other files, a person of ordinary skill would ignore the teachings that ASX files are used by Windows Media Player.” slip op. at 23

We agree and find that the ’635 patent is not entitled to that earlier date for the reasons given by Petitioner. As Petitioner points out, the ’519 application does not refer to a play script. Reply 8. The written description of the play script was not added until 2002. Id. Patent Owner contends that in the priority documents, “play script is used interchangeabl[y] with play list.” PO Resp. 34–45. Patent Owner fails to demonstrate persuasively that lacking the 11 description added in 2002, the “play list” disclosed in the ’519 application has the required elements of the play script claimed in the ’635 patent. Reply 12. One of those required elements of the claimed play script is “one or more instructions for use by the communication device together with the at least one URL to cause the at least one portion of the requested media to be streamed to the communication device.” See claim element 1.c.4, Ex. 1001, 51:8–11. We find that there is inadequate written description in the ’519 application of “instructions . . . to enable the communication device to obtain the at least one portion of the requested media.” Reply 8–9. We agree with Petitioner that the “presentation identification” relied on by Patent Owner (Ex. 2015, 7) does not provide “instructions…to enable the communication device to obtain the at least one portion of the requested media.” Reply 13. Instead, the “presentation identification” “identifies a particular presentation . . . and its associated media.” Id. (quoting PO Resp. 36). Absent an adequate written description in the ’519 application of these claimed features, Patent Owner’s attempt to obtain the benefit of the filing date of that application for the challenged claims of the ’635 patent fails. “It is elementary patent law that patent claims are entitled to the benefit of the filing date of an earlier filed application only if the disclosure of the earlier application provides support for the claims of the later application, as required by 35 U.S.C. § 112.” PowerOasis, Inc. v.
