    “III. ANALYSIS A. Level of Ordinary Skill in the Art Petitioner asserts that a person of ordinary skill in the art: would have had at least a bachelor’s degree in computer science, electrical engineering, or a related field, and at least two years of work or research experience in the field of content delivery management or networks. Work experience can substitute for formal education and additional formal education can substitute for work experience. Pet. 12 (citing Ex. 1006 ¶ 70). Patent Owner asserts that “the Board does not need to resolve the appropriate level of skill for a POSA [person of ordinary skill in the art] for purposes of deciding institution because the Petition fails under any articulation of a POSA.” Prelim Resp. 10.

  • Disclosure Requirements (§112) › Written description (Ariad)Written description adequateEntitled to earlier dateDecided for patent owner

    “We consider the disclosures of the Provisional Application, which refer to cases 1 and 2, in which requests are redirected to an origin server for lower popularity content and to a parent server for medium popularity content at steps 522 and 524 as shown in Figure 5, respectively, wherein the edge server receives a redirect from the popularity service without a “followme” flag. See Ex. 1011 ¶¶ 43, 44. The Provisional Application also discloses that, by comparison, if there is a “follow-me” redirect sent to the edge server, it obtains and caches a resource as shown at step 528 for higher popularity content. Id. ¶ 44. On this record, as Patent Owner asserts, these disclosures are consistent with technical reasons provided in the Provisional Application for instructing the edge server not to cache unpopular resources. See Ex. 1011 ¶¶ 68–69. In light of these disclosures, we preliminarily find support for Dr. Shenoy’s testimony that, even with the words “instruction to not cache” are not literally recited in the Provisional Application, caching and not caching are alternative options that indicate the instruction to the edge server that will be implemented for each option. See Ex. 2014 ¶ 56. Further, these disclosures provide support for Dr. Shenoy’s testimony that the disclosures “reasonably convey to those skilled in the art that Patent Owner had possession of the edge server receiving an instruction to not cache the resource (and instead simply forward the redirect).” Id. In re Johnson states that “it is not true that the factual context out of which the question under § 112 arises is immaterial. Quite the contrary. Here, . . . the ‘written description’ in the [] specification supported the claims in the absence of the limitation, and that specification, having described the whole, necessarily described the part remaining.” See Johnson, 558 F.2d at 1019. This is consistent with M.P.E.P. § 2173.05(i) which states, “[i]f alternative elements are positively recited in the specification, they may be explicitly excluded in the claims.” M.P.E.P. § 2173.05(i). Further, “the failure of the specification to specifically mention a limitation that later appears in the claims is not a fatal one when one skilled in the art would recognize upon reading the specification that the new language reflects what the specification shows has been invented.” All Dental Prodx, LLC v. Advantage Dental Prod., Inc., 309 F.3d 774, 779 (Fed. Cir. 2002). Even though we do not discern that the Provisional Application explicitly discloses an “instruction to not cache,” at least on this preliminary record, and for the purposes of this Decision, there is positive recital of instructions to cache in the Provisional Application and Petitioner has provided sufficient supporting evidence that caching and not caching are alternative options. Further, there is sufficient evidence, in the context of the disclosures of written description support in the Provisional Application, providing support for Dr. Shenoy’s testimony that Patent Owner had possession of an edge server receiving an instruction to not cache the resource. Nonetheless, we invite additional briefing on these issues, including issues relating to alternative options of caching and not caching. On this preliminary record, we find that the ’573 patent has a priority date of April 2, 2008, which predates the earliest possible date on which Newton-471 could be effective as prior art, September 30, 2014 (the date on which the earliest application in the priority chain of Newton-471 was filed). Accordingly, we preliminarily find that Newton-471 is not prior art to the challenged claims. Thus, on the present record, Petitioner has not demonstrated a reasonable likelihood that it would prevail in showing that claims 1–20 are anticipated by Newton-471.” slip op. at 13

To comply with the “written description” requirement of 35 U.S.C. § 112, first paragraph, an applicant must “convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention. The invention is, for purposes of the ‘written description’ inquiry, whatever is now claimed.” Vas-Cath, Inc. v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed. Cir. 1991) (emphasis omitted).

The question of written description support should not be confused, however, with the question of what would have been obvious to the artisan. Whether one skilled in the art would find the claimed invention obvious in view of the disclosure is not an issue in the “written description” inquiry. In re Barker, 559 F.2d 588, 593 (CCPA 1977). “A description which renders obvious the invention for which an earlier filing date is sought is not sufficient.” Lockwood, 107 F.3d at 1572.” slip op. at 11

(citing, inter alia, Ex. 1003 ¶¶ 70–71; Ex. 1007 ¶ 23). Patent Owner does not present any arguments on the rationale to combine. See generally Prelim. Resp.

  • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted

    “We agree with Patent Owner that its understanding of a policy as a rule is consistent with the disclosure in the ’517 patent that “a policy may be created by generating a decision tree representing the ATC rules.” See Ex. 1001, 9:1–3. We do not agree with Patent Owner, however, that Beaumont in combination with Hasan does not disclose the claimed policy features as claimed. As discussed above, Petitioner relies upon Beaumont in combination with Hasan with its teachings on the use of Java-based GUIs in the form of a tree structure that allows administrators to configure device and service configuration data, as well as policy information. See Ex. 1006, code (57), 7:7–26, 8:19–29. For the policy teachings, Petitioner relies upon Beaumont’s “content provider DNS server that directs requests (traffic) according to a preference table (policy).” Pet. 15–16 (citing Fig. 1, ¶¶ 6, 17, 23). Petitioner also asserts that the Beaumont-Hasan GUI would enable an administrator to set policies for a selected content delivery server to allow setting server preferences and rules. Id. at 17–18 (citing, inter alia, Ex. 1007 ¶¶ 76–77). In support, Dr. Lin testifies that: The Beaumont-Hasan GUI would enable an administrator to select a content delivery server (e.g., in Japan) and set policies for that server. Hasan, 8:30–36, 10:25–34, 10:53–67; Beaumont, [0031]. For example, given the description in Hasan, selecting a server would bring up a menu enabling an administrator to assign the preferences shown in Fig. 3 of Beaumont. Hasan, 10:25–34; Beaumont, Figs. 2, 3, [0029]–[0031]. A POSITA would thus have recognized the combined GUI to “support[] the setting of said at least one policy using a decision tree representing rules” because it is presented in a “familiar tree structure” and would allow users to set server preferences and rules. Ex. 1003 ¶ 77 (emphasis added). Beaumont provides support for Dr. Lin’s testimony. Beaumont discloses that “rules such as selecting one [a server] based on user preferences can be used . . . [f]or example, a preference number can be assigned to each content delivery server and a destination domain.” Ex. 1007 ¶ 31. Beaumont further states that “FIG. 3 shows an illustrative example of incorporating preference numbers in a column.” Id. Thus, contrary to Patent Owner’s arguments, Beaumont discloses that rules or policies, represented by the preference number, are represented in the table shown in Figure 3 of Beaumont. Dr. Lin also testifies that in the Beaumont-Hasan combination “the GUI supports the setting of” policy is taught. Ex. 1003 ¶ 77. Hasan provides support that service policies can be modified by the use of a GUI. See Ex. 1006, 8:30–36, 10:25–34, 10:53–67. Accordingly, in the combination of Beaumont and Hasan, wherein the preference database is replaced by the GUI decision tree, Petitioner has provided sufficient evidence at this juncture that the combination of Beaumont and Hasan teaches that the GUI obtains a policy, the preference number, for the direction of network traffic, where the GUI supports the setting of the policy using a decision tree representing rules.” slip op. at 19

    “We agree with Patent Owner that the recited second type SIBs exclude first type SIBs. 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). Despite Petitioner’s argument that this disclosure is non-limiting and directed to a disclaimed example embodiment (Opp. 8–9), Petitioner could not identify any embodiment, among the approximately forty disclosed embodiments, describing something other than the first type SIB being essential information and the second type SIB being non-essential information. Tr. 22:18–26. Even the Petition acknowledges that “the ’958 Patent further classifies a second type of system information, the ‘non-essential’ SI, which is defined as all other types of information excluding that first type of information required for initial access.” Pet. 5. Furthermore, the prior art of record suggests that a person of ordinary skill would have understood second type SIBs exclude first type SIBs. See Ex. 1008 ¶ 48 (describing two categories of system information, “essential SI” and “Other SI”). Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13. For the above reasons, we do not agree with Petitioner that the recited second type SIB lacks any requirements, nor do we interpret claims 7 and 8 such that the first type SIB could be a second type SIB.” slip op. at 19

For example, Petitioner did not map the recited “group identifier” when opposing Patent Owner’s Revised Motion to Amend. See Opp. 16–17.

Petitioner similarly failed to address adequately where Lee discloses or suggests the recited “compressed format” and “plural parameters.” See Opp. 16–17. 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. Sur-reply 12. This conclusory statement is not supported by any citations to evidence and was improperly introduced in the Sur-reply. 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.

The Burden of Persuasion “In an inter partes review . . ., the petitioner shall have the burden of proving a proposition of unpatentability by a preponderance of the evidence.” 35 U.S.C. § 316(e). That burden, termed the burden of persuasion, “is the ultimate burden assigned to a party who must prove something to a specified degree of certainty.” Dynamic Drinkware, LLC v.

Seet expressly defines the claim term “media,” stating that, as it is “used herein,” “media” includes audio, video, software, and pictures. Ex. 1006 ¶ 50 (“Media content may include one . . . of audio . . ., video . . ., software . . ., and pictures”). Such a statement provides a clear definition of the term “media” that includes video, software, and pictures, in addition to audio. In addition to the express definition, Seet elsewhere indicates that its media includes video and other non-audio signals and databases.

    “(3) Conclusion – Written Description In view of the above, we find that either disclosure in Barsoum identified by Patent Owner satisfies the written description requirement. 2. 35 U.S.C. § 103 As noted previously, Petitioner argues that dependent claims 5, 15, and 25 are obvious over the combination of Barsoum and ATSC327. Pet. 67–79. Having determined the Barsoum provides written description support for claims 5, 15, and 25, Barsoum cannot be prior art under 35 U.S.C. §102(a)(1) as asserted by Petitioner. Pet. 2; 35 U.S.C. § 102(a)(1) (requiring that “the claimed invention was patented . . . before the effective filing date of the claimed invention). Furthermore, having determined that the ’700 patent is entitled to an effective filing date of Barsoum ’777, which is June 5, 2008, the asserted March 2019 date of ATSC327 does not qualify it as prior art to the ’700 patent. Thus, the Petition does not establish by a preponderance of the evidence that claims 5, 15, and 25 are obvious over the combination of Barsoum and ATSC327.” slip op. at 22
