“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. However, the clear description of an embedded patent, more strongly guides our preliminary construction.” slip op. at 9

“We are persuaded by Petitioner’s assertions for limitations [15pre]– [15a]. Dr. Mowry attests that Verna’s client browser sends a URL 28 to a content provider 22, which is then forwarded to broker 25, which selects the appropriate cache server to serve the content and returns a re-written URL to the content server that received the client request. Ex. 1003 ¶ 67 (citing Ex. 1005 ¶¶ 12, 26, 27, 37). On the current record, this function of Verna’s broker fulfills Dr. Russ’s characterization of an API as acting as bridge establishing a connection between client and server. Ex. 2010 ¶ 50. Verma also meets Dr. Russ’s characterization of an API as “an interface that allows the client to communicate with an application executing on the server.” Ex. 2010 ¶ 50. Dr. Russ describers Verma’s broker as sending availability inquiries from the content provider (client) to servers 23 and 24 to “find out whether they currently store the requested movie file,” and provide that information back to the content provider (client). Id. ¶ 53. On the current record, this function of Verna’s broker fulfills Dr. Russ’s characterization of an API acting as an interface that allows the client to provides availability information to the broker).

“On the current record, we are persuaded by Petitioner that Kenner’s video ID is associated with a shared repeater server. As noted by Patent Owner, Kenner’s video ID includes content coordinate data that may “match with the regional IMs [repeater servers] that have subscribed to that type of file.” Prelim. 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

- 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

“protective layers have “a coat weight of from 5 to 30 lbs/3000 ft2,” Clearwater submits the declaration of its expert, who explains that, because Nakagawa identifies the specific polymers and the thickness of the coat used for the plastic layers and one skilled in the art “would recognize that the disclosed polymers have a given density,” then “[w]ith these known parameters, the coat weight is easily calculated to be 23.04 lbs./ 3000 ft2 — falling squarely within the claimed range.” Pet. 53–54 (citing Ex. 1003 ¶¶ 132–133; Ex. 1008 ¶ 24; Ex. 1024, at 4). At this stage, we find that testimony credible and supported by the evidence presently of record. After reviewing the preliminary record (including Clearwater’s contentions, the cited portions of Nakagawa, and the testimony of Clearwater’s expert), we find, preliminarily, that Nakagawa discloses or otherwise suggests each claim element in the manner recited by claim 1. Thus, on the current record, Clearwater demonstrates a reasonable likelihood that challenged claim 1 is unpatentable as obvious over Nakagawa. We need not decide Clearwater’s challenge of the dependent claims based on Nakagawa alone nor its challenge of claims 1–3 based on Nakagawa and Tanner.

“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

“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. Cir. 2015) (“[o]bviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed inventions.”). Dr. “content providers” limitation, stating that it “would have been nothing more than replicating Glines’s teaching of storing and providing content associated with one origin server, with expected results.” Ex. 1008 ¶ 263. That statement, however, is unsupported, and moreover, does not explain how such replication would occur or what results would be expected. Prelim. Resp. 25–26. At this stage in the proceeding, Dr. Mowry’s testimony amounts to a “conclusory generalization” that does not provide the “reasoned explanation” sufficient to show that a limitation missing in the cited art was taught by the knowledge in the art.

RulingsRemand decision- RemandOther
“On February 12, 2025, the Federal Circuit issued an opinion vacating and remanding our Final Written Decision based on the determination of the construction of the impingement term recited in the ’170 patent. Appeal Dec. 9. More specifically, the Federal Circuit found that the Board’s construction was too limited. Id. at 8–9. The Federal Circuit found that As properly construed, in the context of the challenged claims, ‘impingement of an electromagnetic radiation spot’ must include ‘reflected, projected, and interrupted or blocked radiation.’ In other words, when a finger or non-light-emitting stylus interrupts or blocks a beam of electromagnetic radiation, and does so over a certain spot on the surface of a device, the claim limitation is satisfied. Contrary to the Board’s construction, as articulated by Power2B on appeal, the ‘electromagnetic radiation spot on . . . [the] interactive surface element’ does not ‘require[that] radiation imping[e] on the surface element’ and, hence, does not exclude interrupting or blocking radiation. Appeal Dec. 9 (citations omitted).” slip op. at 3

“better definition for purposes of this proceeding, except we again decline to adopt “at least” because that language is vague and open-ended. With respect to the educational qualifications, Petitioner’s proposed qualifications are that one of ordinary skill in the art would have had a bachelor’s degree in electrical engineering, computer engineering, computer science, or a related field. Pet. 8 (citing Ex. 1002 ¶ 41) (emphasis added). The claims are directed to an interactive assembly comprising at least one input sensor to provide an output indicative of an impingement of an electromagnetic radiation spot. Individuals with bachelor’s degrees in physics would be knowledgeable in researching, designing, or developing such assemblies and would be able to comprehend and evaluate the teachings of the prior art. Accordingly, Petitioner’s proposed qualifications are overly narrow in not including individuals with bachelor’s degrees in physics. With respect to work experience, a person having two years of experience would be able to comprehend and evaluate the teachings of the prior art, consistent with Petitioner’s proposal.” slip op. at 10

“impingement of an electromagnetic radiation spot” includes “reflected, projected, and interrupted or blocked radiation” and “when a finger or nonlight-emitting stylus interrupts or blocks a beam of electromagnetic radiation, and does so over a certain spot on the surface of a device, the claim limitation is satisfied.” Appeal Dec. 9. Under this construction, we determine that Petitioner has demonstrated that Newton teaches this claim limitation. More specifically, Newton discloses that a user touch interrupts beams of electromagnetic radiation over certain spots over a surface, which provides an output.

“We agree with Petitioner that the claims do not require a detector assembly to be physically separate from the interactive surface element. The language of the claims does not require this, nor is there any disclosure in the ’170 patent specification that indicates that separation of these elements is required. Patent Owner refers to certain embodiments that have separate structures, but we decline to import this as a requirement to the claim term. We also agree with Petitioner that the ’170 patent broadly views what it means to be “at an edge,” and that can include being behind, about, or along an edge within its scope.

“The parties’ proposed levels of ordinary skill in the art are similar, although Patent Owner proposes two years of experience along with a bachelor’s degree whereas Petitioner proposes “significant” experience. Patent Owner also proposes an alternative with more extensive experience in lieu of a bachelor’s degree. Although we find Petitioner’s proposed qualifications acceptable, we adopt Patent Owner’s proposed qualifications for the purposes of this Decision because they offer a wider range of qualifications that nonetheless comport with the level of ordinary skill necessary to understand and implement the teachings of the ’504 patent and the asserted prior art.

“We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses element [1.2] because the evidence cited does not disclose a “first computer system being configured to provide remote control of the first pump or first valve” (i.e., a fluid-handling device). Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but Petitioner has not identified any disclosure of the capability to remotely control fluid-handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, Kahn’s disclosures that Petitioner relies on for allegedly teaching remote control are deficient. We discuss each. First, Petitioner points to the following, “[f]or instance, as illustrated in FIG. 1C, a fluid control device such as a valve 15A is located on the input side of a sen[s]or unit 110.” Ex. 1005, 8:19–21, cited in Pet. 13. This portion of Kahn, however, does not disclose remote control. Second, Petitioner cites to the following: Finally, or in addition to, the communication unit 112B can include on-site alerts such as optical (indicator lights), audible alerts (e.g., alarm sounds), tactile (e.g., vibration of the unit) or can be interfaced to an appropriate control valve for simply shutting off the supply of fluid upon the detection of emergency events, for instance. Pet. 13 (citing Ex. 1005, 10:62–67). We agree with Patent Owner that this portion of Kahn teaches on-site alerts and local control of the fluid-handling device. See Prelim. Resp. 7. This portion of Kahn does not disclose remote control.” slip op. at 18
