“The ’655 patent Specification states that: The topology data table 21 of the online server 20 is mainly recorded with a link data 49 between each of the P2P devices 41– 46 within the P2P device community. The link data 49 refers to the connection relationship between the P2P devices 41–46, which includes, but is not limited to, the connection structure, connection data and/or locations of connection. Ex. 1001, 4:51–57. On this preliminary record, we agree with Petitioner that the term “link data” is a “connection relationship between the P2P devices.” This meaning is consistent with the ordinary meaning of the term within the context of the claim, that is, “link data” means data on the links (connections) between each of the P2P devices, where the Specification provides a more fulsome meaning that the term includes, at least, “the connection structure, connection data and/or locations of connection.” See id. at 4:55–57.

We determine that this disclosure provides support for Mr. Lett’s testimony that “Lee describes techniques for changing an overlay in response to changing network characteristics,” which could be beneficial.

“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. ORDER For the reasons given, it is ORDERED that pursuant to 35 U.S.C. § 314, an inter partes review is instituted as to claims 1, 2, 5–8, 11, and 12 of the ’803 patent to determine whether: 1) claims 1, 5–7, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over TS 36.300, TS 36.321, and TS 36.331; 2) claims 1, 2, 5–8, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over Ericsson and TS 25.331; and 3) claims 5, 6, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over Ericsson, TS 25.331, and Sebire; and” slip op. at 27

“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.

“On the current record, we determine that the “modified embedded resource” may be a “link.” Both Petitioner and Patent Owner point to claim 13, which explicitly states that a modified embedded resource is a link. Because claim 13 depends from claim 1, claim 1 must be broad enough to encompass a modified embedded resource that is a link. Patent Owner also points to a statement in the ’322 patent that “[t]he embedded resource is a link.” Prelim. Resp. 18 (citing Ex. 1001, 4:26–31). Patent Owner argues that every embodiment of the ’322 patent “involves embedding the ‘modified embedded resource’ in another resource when it is returned to the client.” Paper 16, 2–3. Patent Owner cites to description in the ’322 patent of a “document” or a “page” returned to the requesting client. Id. (citing Ex. 1001, 4:42–48, 7:48–55). However, claim 15 does not return the modified embedded resource to the client, only the origin system. Claim 1 recites only that the “modified embedded resource” is returned to the client device with the content resource. Neither claim 1 nor claim 15 recite returning a document or a page containing the modified embedded resource, only the modified embedded resource itself. We acknowledge some tension with the adjective “embedded,” which Patent Owner argues requires that the embedded resource be embedded in something. Paper 16, 1–3.

“On the current record, we are persuaded by Petitioner that Kenner’s video ID is associated with a shared repeater server.

Resp. 35 (citing Ex. 1005, 36:20–30). Kenner describes that content coordinate data is maintained on a database of each IM, which includes the Internet address of all other connected IMs and content coordinate data describing the type of files stored by the SRUs of each IM. Ex. 1005, 41:1–6. That content coordinate data, stored in each video ID and each IM, teaches the claimed association of alias with repeater server. Because the content coordinate data directs the PIM to the repeater server(s) having that particular data, Kenner’s user does not always access the same repeater server, and Patent Owner’s argument is unavailing.” slip op. at 12

“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).

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 invention claimed does not have to be described in ipsis verbis to satisfy the written description requirement. Union Oil Co. v. Atlantic Richfield Co., 208 F.3d 989, 1000 (Fed. Cir. 2000). 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

Petitioner argues that “Beaumont does not describe a specific interface for manually entering [policy and rules] preferences, Hasan discloses a GUI for exactly this type of policy specification.” Id. at 14 (citing Ex. 1003 ¶ 70). Petitioner asserts that Hasan discloses that its Java-based, “platform independent” GUI takes the form of a “familiar tree structure” and allows administrators to “configure device and service configuration data and policy information.” Id. (citing Ex. 1006, code (57), 7:7–26, 8:19–29, 18:9–20). Petitioner asserts that the combination of Beaumont and Hasan would have been straightforward, and a person of skill “would have been motivated to incorporate Hasan’s GUI so that administrators could conveniently configure preferences for Beaumont’s DNS servers through an intuitive interface.” Id.

“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 find that the intrinsic evidence supports maintaining our construction in the Institution Decision that “insulating” means “electrically insulating.” See Dec. 11–12. In particular, we agree with Patent Owner’s argument that the insulating barriers would be unable to be configured to “block[] substantially all through-air arcing paths between the first and second electrical contacts,” as claimed, unless they were electrically insulating. See Ex. 1001, 4:36–44. Moreover, as Patent Owner avers, our interpretation of “insulating” as it applies to the first and second insulating barriers should be the same as for the first and second housings.

“Id. at 3:27–37 (emphasis added). These wall portions 58 are located between the distal ends of the terminals and where Petitioner proposes to add a printed circuit board or wiring board to Winkler. See id. at Fig. 2; Pet. 44–46 (diagrams showing Winkler as modified to have a printed circuit board or wiring board). As such, movement of Winkler’s terminals appears to be mostly limited to within their respective receiving pockets. Given the above teachings, we fail to see how Petitioner’s proposed modification would have meaningfully interfered with the degree of freedom of movement required by Winkler’s terminals. Notably, Mr. Locati’s testimony regarding this issue is conclusory. See Ex. 2001 ¶ 120. Because movement of Winkler’s terminals occurs primarily in the receiving pockets, we also do not discern how the solder joint of Petitioner’s proposed modification would experience undue stress or risk breaking due to that movement. See Ex. 1004, 1:47–55, 3:14–37, Fig. 2; Pet. 44–46. This is particularly true in view of Winkler’s teaching that each cylindrical end portion may be soldered to a cable. See id. at 2:6–10; see also Pet. 43 (arguing that Winkler teaches soldering to a cable but not specifically to a printed circuit or wiring board). Accordingly, we determine that Petitioner has shown by a preponderance of the evidence that claim 8 would have been obvious over the combined teachings of Winkler and Handbook.” slip op. at 55

“Dr. Mowry further attests that “A POSITA would have understood Glines’s disclosure of providing content from an origin source would have included supporting more than one origin source (e.g., more than one website or content provider[)].” Ex. 1008 ¶ 262 (citing Ex. 1002, 12:11–22 (storing replica files that originate at an origin server 40), 13:21–14:3 (requesting “example.com”)). That statement, however, goes only to what Glines might be capable of doing, not to whether one would have modified Glines to do so. See Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed.

Although Patent Owner has proposed a slightly different statement for the level of ordinary skill in the art, Patent Owner does not explain why Petitioner’s proposal is incorrect.

“We need not resolve the above-identified dispute, because a different aspect of “beforehand locally stored” is determinative. Read in context, “beforehand locally stored” in both limitations 1(a)(2) and 12(a) refer back to the “preliminary search” action recited in limitation 1(a)(1) and in limitation 12(a) itself, respectively. Thus, we construe “beforehand locally stored” to mean that the selection pages must already be stored within the communication device when the user begins the preliminary search, regardless of whether it was the user or an automated process that downloaded the selection pages to the communication device. This understanding stems from a plain reading of the claim language and does not leave room for reasonable doubt otherwise.

“of the language in these limitations is that the selection pages must be beforehand locally stored, where beforehand is assessed at the time of starting a preliminary search. Based on this construction, Petitioner has not sufficiently shown that Rossman discloses limitation 1(a)(2) and limitation 12(a), even for institution purposes. Petitioner identifies Rossmann’s cards as the claimed selection pages of claims 1 and 12. Pet. 18–19. Rossmann’s cards, however, are not beforehand locally stored on the communication device at the time a user begins a preliminary search for information. Rather, on the record before us, at the time of starting a search for information, the user must request a connection to a server device at a desired host site, which request results in the server device at the host site sending one or more decks each including a plurality of cards to the user’s mobile device. Ex. 1004, 6:26–29; 7:22–27; 7:56–66. Thus, Rossmann’s cards are not beforehand locally stored at the time the user commences a preliminary search.
