“CLAIM CONSTRUCTION B. In an IPR, we construe a patent claim “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b).” 37 C.F.R. § 42.100(b). This generally includes “construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” Id. The ordinary and customary meaning of a claim term “is its meaning to the ordinary artisan after reading the entire patent,” and “as of the effective filing date of the patent application.” Phillips, 415 F.3d at 1313, 1321. Neither Petitioner nor Patent Owner argues that we need to construe any claim terms explicitly. See Pet. 2–3; Prelim. Resp. 9. However, the parties’ positions depend on interpreting the claim language in a particular way, and we discuss the relevant claim language below in the context of the parties’ arguments regarding the prior art. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

“At this stage, we find Petitioner’s arguments persuasive and disagree with Patent Owner. Patent Owner appears to equate a “fabrication profile” with a toolpath description, but nothing in the plain language of claim 1 supports that narrow interpretation. The ’774 patent describes a “fabrication profile” broadly and states that the profile can simply “include the dictionary [of configuration information],” or be “used to determine which machineready representation is available or suitable for a target printer.” Ex. 1001, 23:49–52. The preliminary evidence suggests that Douglas’s “operational parameters” would count as a “fabrication profile” because it is “the basis for generation of a machine-ready representation of the three-dimensional model that is executable on the target printer.” Id. at 23:37–39; see infra Section III.C.8. We also disagree that Petitioner’s argument is impermissible hindsight, because it is based on the disclosures in Douglas and Mark, and Petitioner has articulated a sufficiently persuasive reason to combine those references without referring to the ’774 patent itself. 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”). Finally, Petitioner appears to rely on Mark for providing a particular example of a fabrication profile, not to replace Douglas’s overall system in which the 3D printer can receive “operational parameters” rather than just G-code. See Pet. 8–10, 17–23; see also Ex. 1005 ¶ 41 (the print queue, which stores tool instructions, may be maintained locally on printers 204 or on print servers 208); see In re Mouttet, 686 F.3d 1322, 1332 (Fed.

“distinguishes and contrasts build material property from operational parameters. The diagnostic test passage therefore only describes a diagnostic test of the build material property but does not describe a subsequent diagnostic test to assess whether an operational parameter is suitable for the printer. Based solely on the diagnostic test passage and the prosecution history, a possible interpretation may be that the operational parameter determination in claim element 1b encompasses the diagnostic testing in claim element 1c. That is, “performing a diagnostic test to determine whether the operational parameter is suitable for the three-dimensional printer” in claim element 1c is subsumed as part of “determining an operational parameter of a fabrication process using the three-dimensional printer based upon the data, the operational parameter including at least one of a build platform temperature, a build volume temperature, an infill requirement, a rafting requirement, a support structure requirement, and a cooling requirement” in claim element 1b.” slip op. at 15

“presented in the petition . . . and any response . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a). Having reviewed the parties’ papers and the evidence of record, we determine that Petitioner has shown a reasonable likelihood it would prevail in establishing the unpatentability of at least one challenged claim. Accordingly, we institute an inter partes review on all challenged claims and on all grounds raised in the Petition. See 37 C.F.R. § 42.108(a) (“When instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.”).” slip op. at 2

“B. Level of Ordinary Skill in the Art Petitioner asserts a person of ordinary skill in the art in May 2004 would have had a working knowledge of the telecommunications and networking art that is pertinent to the [’911 patent]. A POSITA would have had a bachelor’s degree in electrical engineering, computer science, computer engineering, or an equivalent, and two years of relevant experience involving computer science fundamentals, including pointers, data structures, object-oriented programming, database principles, internet-based communication technologies and electronic mail systems that is pertinent to the [’911 patent]. Lack of professional experience can be remedied by additional education, and vice versa Pet. 3 (citing Ex. 1003 ¶ 22). Patent Owner asserts a person of ordinary skill in the relevant art — computer science — would have at least a bachelor’s degree in electrical or computer science/engineering, or a related field, with at least two years of experience in the design or implementation of content management and analysis systems or a master[’s] degree in electrical or computer science/engineering, or a related field, with at least one year of experience in the design or implementation of content management and analysis systems. A higher level of education or skill can make up for less experience, and vice versa. Prelim. Resp. 17 (citing Ex. 2002 ¶ 14). For purposes of this Decision, we adopt Petitioner’s proposed level of skill, as articulated above. Petitioner’s proposed definition generally teachings of the ’911 patent and the asserted prior art. Cf. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (noting that the prior art itself may reflect an appropriate level of skill in the art). This definition is also supported by the testimony of Dr. Black.” slip op. at 9
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner
“relational references” require using a relational model (or that they are a relational model) and, for purposes of this decision, we adopt Petitioner’s proffered construction. The relevant portion of claim 1 recites “a message container containing relational references pointing to a plurality of sent submessages stored externally to the message container in the message database.” Ex. 1001, 15:56–59. That express language does not recite a relational model, let alone that “relational references” connote required use of a relational model. Instead, the language supports Petitioner’s interpretation that “relational references” are pointers that point to related messages because the claim states that the “relational references” perform the task of “pointing to a plurality of sent submessages.” Although Patent Owner asserts that “pointers pointing” would be redundant (Prelim. Sur-reply 3), we disagree. In addition to being different parts of speech, i.e., a pointer is a noun and pointing is a verb defining what the noun is doing, the claim does not merely recite “relational references pointing.” Rather, Petitioner’s proposed construction outlines what the “relational references” include, i.e., “pointers,” and claim 1 further limits what the “relational references” are “pointing to,” i.e., “to a plurality of sent submessages.” Prelim. Resp. 9. Further, the Specification supports adopting Petitioner’s construction over Patent Owner’s. The Specification does not state that “relational references” require the use of, or are, a relational model, as Patent Owner argues. Rather, any discussion of “relational references” in the Specification describes them as message components that refer to content or other data, e.g., a pointer. Ex. 1001, 3:6–16 (“a message is a container having relational references to content and/or audit data”); see id. at 1:67–2:2, 4:61–64, slip op. at 11
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner
“We agree with Petitioner that the ordinarily skilled artisan would have been motivated to combine Rohall and Schiavone because Schiavone provides reasons to apply its techniques to email systems such as Rohall’s. Schiavone describes a need for “ensuring compliance of e-mail messages with applicable standards and/or laws and/or otherwise determining appropriateness of a message for an intended recipient,” especially because there is “a patchwork of local, federal and international laws.” Ex. 1006 ¶ 6. Schiavone also states that filtering emails, e.g., to remove spam, is beneficial. Id. ¶¶ 1–2. As Schiavone describes problems in email systems, adequately shows that the ordinarily skilled artisan would have been motivated to combine Rohall and Schiavone. See KSR, 550 U.S. 401 (a reference which teaches, suggests, or motivates its combination may “identify a reason that would have prompted a person of ordinary skill in the art to combine the elements”).” slip op. at 17

“III. CONCLUSION Based on the arguments and evidence presented by the parties, we conclude that Petitioner has not demonstrated a reasonable likelihood of prevailing with respect to at least one claim of the ’634 patent challenged in the Petition. Therefore, we do not institute an inter partes review. IV. ORDER In consideration of the foregoing, it is hereby: ORDERED that the Petition is denied and no inter partes review is instituted.” slip op. at 25

“B. Level of Ordinary Skill in the Art Petitioner argues that at the time of the ’634 patent (July 2018), a person of ordinary skill in the art would have had “a bachelor’s degree in electrical engineering, computer science, computer engineering, or a similar major with at least two years of experience in the field; or a master’s degree with specialization in the field,” where “[a] person with less education but more relevant practical experience may also meet this standard.” Pet. 7 (citing Ex. 1003 ¶¶ 12–13). Petitioner further argues that a person of ordinary skill in the art would have had knowledge of “[d]esigning and using systems that include endpoint devices (e.g., client devices) and servers for establishing network connections and data transfer,” “[r]ecognizing and applying the client-server architecture,” and “[u]sing and applying concepts from known telecommunication and networking frameworks, protocols and standards, including TCP/IP, IEEE 802.11, VoIP, cellular systems and other known frameworks and standards.” Id. (citing Ex. 1003 ¶ 14). Patent Owner does not address the level of ordinary skill in the art in its Preliminary Response. Based on the record presented, including our review of the ’634 patent and the types of problems and solutions described in the ’634 patent and cited prior art, we agree with Petitioner’s definition and apply it for purposes of this Decision. See, e.g., Ex. 1001, col. 1, ll. 4–29 (describing in the “Background” section of the ’634 patent a “network connection between two endpoints” and known methods of reaching “full effective bandwidth capacity” in a network).” slip op. at 8

“C. Claim Interpretation We interpret each challenged claim using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b). Petitioner notes that it proposed a construction for the claim term “geographical area” in the district court case, but states that it “do[es] not believe proposing a construction for the term is necessary in this proceeding because the relied upon teachings of the prior art references are consistent with examples of ‘geographical area’ included in the ’634 patent [S]pecification.” Pet. 8. Patent Owner argues that “[t]he Board need not engage in express claim construction at this stage of the proceeding.” Prelim. Resp. 5. We conclude that no express interpretation of any claim term is necessary to determine whether to institute an inter partes review in this proceeding. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“Because we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy,’ we need not construe [a particular claim limitation] where the construction is not ‘material to the . . . dispute.’” (citation omitted) (emphasis added)).” slip op. at 9
- BurdenNot shown unpatentable
“Petitioner has not shown sufficiently that Erskine teaches or suggests the second requirement of limitation [1c], i.e., “initiating the next network connection . . . with a transmission bandwidth based on the parameter values for the past network connection.” Petitioner’s theory is that (1) the QoS parameters in Erskine are for a “past” connection from one zone to another, (2) the sliding maximum interzone bandwidth is “based on” the QoS parameters, and (3) a new call only proceeds if the transmission bandwidth needed for the call added to the current bandwidth being used over the interzone link is less than the sliding maximum interzone bandwidth, so Erskine therefore teaches a call with a transmission bandwidth determined “based on” the sliding maximum interzone bandwidth (which in turn is determined “based on” the QoS parameters). See Pet. 27–28; Ex. 1003 ¶¶ 59–60 (similar testimony from Dr. Crovella). As Patent Owner points out, however, Erskine only makes “a binary, accept/reject decision as to whether to allow a new call to proceed based on a comparison between the bandwidth needed for the call and a predetermined ‘sliding maximum interzone bandwidth value.’” See Prelim. Resp. 6–7. Specifically, the additional bandwidth that would be needed for the call is added to the current bandwidth being used on the interzone link; if the sum of those values is less than the sliding maximum interzone bandwidth for the link, the call “proceeds”; otherwise, it is “blocked.” Ex. 1004, col. 4, ll. 36–40, col. 6, l. 55–col. 7, l. 10, col. 8, ll. 36–43, col. 9, ll. 9–26, col. 10, ll. 23–25 (the sum is compared to the sliding maximum interzone bandwidth “to determine whether enough bandwidth is available to proceed with the new call”), Fig. 3 (steps 308, 310, and 312). Erskine repeatedly refers to the bandwidth for the new call as the amount of bandwidth that is “necessary” or “required” to handle the call. See, e.g., id. at col. 1, ll. 43–57 (“an amount of bandwidth necessary to handle the new call”), col. 6, ll. 61–64 (“the additional bandwidth required (of the new call)”), col. 8, ll. 36–40 (“the bandwidth necessary for the new call”), col. 9, ll. 16–21 (“the anticipated additional bandwidth necessary for the new call”), 54–56 (“the bandwidth amount the new call will utilize (if connected)”), col. 10, ll. 21–23 (same), 41–43 (same), col. 12, ll. 1–2 (“an amount of bandwidth necessary to handle the new call”). It is that value—determined prior to the addition and comparison to the sliding maximum interzone bandwidth—that will be used for the new call if it is allowed to “proceed[].” Id. at col. 6, ll. 64–67 (if the sum is less than the sliding maximum interzone bandwidth, the call “proceeds” and “the QoS table is updated with the additional bandwidth used by that call”). Erskine does not describe the transmission bandwidth for the new call as being based on any parameter values for a past network connection, but rather as “whatever bandwidth the system determined is necessary for the additional call.” See Prelim. Resp. 8–9. In other words, the transmission bandwidth needed for a new call is predetermined and independent of whatever the sliding maximum interzone bandwidth is currently. See id.” slip op. at 15
