    “Petitioner contends that one of ordinary skill in the art “would have had (1) at least a bachelor’s degree in Mechanical Engineering, Computer Engineering, Chemical Engineering, Materials Science, or a related field, and (2) at least two years of research or industry experience in 3D printing or materials used for 3D printing.” Pet. 5 (citing Ex. 1003 ¶¶ 14–16). Petitioner also argues that “[a]dditional experience could substitute for a formal degree or formal training (and vice versa).” Id. Patent Owner proposes a slightly different level of skill, arguing that a person of ordinary skill in the art “would have had a bachelor’s degree in Mechanical Engineering, Computer Engineering, Chemical Engineering, Materials Science, or a comparable field and at least two years of experience related to 3D printing, with additional experience potentially being a substitute for a formal degree or training (and vice versa).” Prelim. Resp. 24. Neither party explains why the outcome of this case would be affected by the adoption of any of the proffered definitions of a person of ordinary skill in the art. We adopt Petitioner’s assessment of the level of ordinary skill in the art, as it appears consistent with the ’324 patent and the asserted prior art. See Okajima v.

    “According to the ’713 patent, “[p]urge tower 24 itself may be . . . recycled or otherwise discarded as desired.” Ex. 1001, 8:27–28. This description provides some support for Patent Owner’s view, because a purge tower too intimately integrated with the part would be difficult or impossible to recycle or discard. This is further supported by the ’713 patent’s statement that “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Id. at 8:30–34. It also is supported by Dr. Hickner’s testimony that the ’713 patent “clearly shows . . . the 24 purge tower separated from the part” and that “the purge tower is a separate physical object.” Ex. 2016, 28:8–10, 64:1–9. On the other hand, there is evidence supporting Petitioner’s view that, as long as the purge tower is generally separate from the part and the support structure, it may still make contact with those portions of the print. As noted above, “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Ex. 1001, 8:30–34. This language does not exclude locations adjacent to or in contact with the part or the support structure. Thus, determine that a “purge tower,” as that term is used in the context of the ’713 patent, may not be an integrated portion of a printed part or support structure but need not be free of all contact with the printed part or support structure.” slip op. at 9

    “There is evidence of record to support both Petitioner’s view and Patent Owner’s view. On the record developed at trial, however, we cannot say that the preponderance of the evidence favors Petitioner, who bears the burden of proof. See 35 U.S.C. § 316(e). Accordingly, Petitioner has not shown by a preponderance of the evidence that KISSlicer teaches printing a layer of a purge tower each time the printer switches one extruder to the operating mode. Because proving the obviousness of claims 1 and 16 requires such a showing, Petitioner has not shown by a preponderance of the evidence that claims 1 and 16 would have been obvious over the combination of Priedeman and KISSlicer. 5. Analysis of Remaining Claims Claims 2, 6, 7, 9, and 17 all depend, directly or indirectly, from claim 1 or claim 16. Accordingly, they all include the limitations of either claim 1 or claim 16. Because, as discussed above, Petitioner has not shown that the combination of Priedeman and KISSlicer teaches or suggests all the limitations of claims 1 and 16, Petitioner also has not proven by a preponderance of the evidence that claims 2, 6, 7, 9, and 17 would have been obvious over that combination of references.” slip op. at 21

    “We agree with Petitioner. Lemay Web discloses that the style settings of width, height, pause, and repeat for the pocket watch images can be changed by changing the values for width, height, pause, and repeat in the HTML file. Ex. 1004, 89–90. This results in changing the size, duration, and frequency of the display of the multiple pocket watch image objects without changing the image files or the Java applet. Id. That is, the 12 image objects of Lemay Web can be uniformly formatted by applying and altering the style settings of the HTML file, which is stored separately from the image objects and the Java applet. Id. at 88– 89. In our Final Written Decision, we wrote that “Lemay Web discloses that the image files that are displayed as the animation object are separate from the HTML.” Ex. 1004, 88–89.” Dec. 22. The Federal Circuit wrote that “how the Board evaluated what constitutes separateness in the prior art software is less than clear.” Opinion, 13 n.7. To be clear, the animation of Lemay Web comprises 12 different pocket watch image objects. Ex. 1004, 89. The HTML file that contains the style settings for the 12 different pocket watch image objects is stored separately from the 12 different pocket watch image objects. Id. at 88–91. The style of the 12 different pocket watch image objects can be altered by changing the values of the style settings in the separate HTML file, thus allowing the style to be uniformly applied to each of the associated 12 pocket watch image objects when the pocket watch image objects are created on the web page. Id.; see Ex. 1030 ¶¶ 28–29; Dec. 21–22. In conclusion for issue (B), we find that Lemay Web teaches applying the style located in the separate HTML file to the pocket watch image objects when creating the pocket watch image objects on the web page. Therefore, Lemay Web’s style is “defined separately from any single object” as claimed. Because Lemay Web’s style can be applied to one object and more than one object and Lemay Web’s style is defined separately from any single object, we find that the prior art combination teaches limitations 1(c) and 1(g) under the proper construction of “style.”” slip op. at 12

    “What you see in the bottom right is an excerpt from the Lemay Web book . . . [y]ou can still use the Java applet just by putting this applet code into your HTML file. So this shows the animator class is going to be run within height or how big a window within the browser should be allocated in this applet. You can . . . tell the animator class how long to pause in between each image. So that’s a style that’s being applied to all of the multiple images that make up this animation. Ex. 2029, 746:23–747:7. Patent Owner then asked GoDaddy’s expert “for each unique animation you want to create with this animator class that’s shown here, you’re going to have to have a unique set of HTML code with the settings along with any of the images you’ll want to associate with the animator class, right?” Ex. 2030, 793:7–11. GoDaddy’s expert testified, with reference to Exhibit 2027, 80, that “Yeah. I’m not a hundred percent sure I understand your question, but yes, if you had six animations on a page, for example, you’d have six blocks of markup that looked like the markup at the bottom right of that slide, starting with applet.” Id. at 793:12–16. In addressing Patent Owner’s question about “each unique animation,” GoDaddy’s expert provided a hypothetical example of a web page having six animations, and explained that the six animations have six blocks of markup. Ex. 2030, 793:13–16. We find that this testimony means that if a web page has six unique animations, then for each unique animation, a corresponding HTML file contains the style settings for the image objects of that animation, such that the “six animations on a page . . . have six blocks of markup.” Id. We find that the subsequent testimony of GoDaddy’s expert cited by Patent Owner is consistent with the expert’s initial testimony that Lemay Web’s style is “applied to all of the multiple images that make up this animation.” Ex. 2029, 747:5–7. We also find that the subsequent testimony is consistent with and supported by the disclosure of Lemay Web, which teaches that an animation has a set of image files and is added to a Web page using the Animator applet. Ex. 1004, 88 (“[Y]ou’ll learn just enough about Java applets to set up animation on your Web page. . . . To create animation using Java and the Animator applet, you’ll need . . . [a] set of image files . . . that make up your animation.”); see id. at 88–91. That is, Lemay Web, consistent with the testimony of GoDaddy’s expert, discloses that the style settings for the animation of the pocket watch in the HTML file are uniformly applied to the 12 pocket watch image objects.

    “determine whether to institute an inter partes review under 35 U.S.C. § 314 and 37 C.F.R. § 42.4(a). Inter partes review may not be instituted unless “the information presented in the petition filed under [35 U.S.C.] section 311 and any response filed under [35 U.S.C.] section 313 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). “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.” 37 C.F.R. § 42.108(a) (2023). In other words, a decision to institute under § 314 may not institute on fewer than all claims challenged in the petition. SAS Inst., Inc. v. Iancu, 138 S. Ct. 1348, 1359–60 (2018). In addition, if the Board institutes trial, it will “institute . . . on all grounds in the petition.” PTAB Consolidated Trial Practice Guide, 5–6 (Nov. 2019)1 (“CTPG”); see also PGS Geophysical AS v.

    “had at least (1) a Bachelor’s Degree (or higher) in material science, materials engineering, mechanical engineering, textile engineering, or a related field, and (2) a minimum of two years of working experience in textiles engineering, fibers and textiles manufacturing, or a related field.” Pet. 4 (citing Ex. 1003 ¶¶ 21–22). Petitioner also argues that “[a]dditional education could substitute for professional experience, and vice versa.” Id. On the present record, Patent Owner does not contest Petitioner’s proposed level of ordinary skill. Prelim. Resp. 25–26. For purposes of this Decision, we adopt Petitioner’s assessment of the level of ordinary skill in the art, as it appears consistent with the ’566 patent and the asserted prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 9

Iancu, 912 F.3d 1368, 1375 (Fed.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

    “articulated a reason why a person of ordinary skill in the art would have combined the teachings of Sudre, Lee, and Penven. Prelim. Resp. 60–63. In particular, Patent Owner argues that a person of ordinary skill in the art “would not have been motivated to look into Penven to modify the teachings of Lee because Lee and Penven disclose substantially different structures.” Id. at 60–61. This argument does not address Petitioner’s proposed reason to combine, which looks to Lee and Penven each to modify Sudre, not to Penven to modify Lee. See Pet. 79–81. In addition, “[c]ombining the teachings of references does not involve an ability to combine their specific structures.” In re Nievelt, 482 F.2d 965, 968 (CCPA 1973). In other words, “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425–26 (CCPA 1981). Petitioner provides “some articulated reasoning with some rational underpinning” to combine the teachings of Sudre with those of Lee and Penven. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). In particular, Petitioner directs us to Sudre’s teaching of “a method for manufacturing PMC,” to Sudre’s lack of teaching of “specific parameters, such as warp thread size and spacing” to satisfy the “particular requirements” of its fabric. Pet. 79 (citing Ex. 1003 ¶¶ 248–250; Ex. 1004, 1:2–5, 6:14–17). As Petitioner points out, id. at 79–80, Lee and Penven provided yarn diameters and loop diameters that were conventional, and there is evidence of record that a person of ordinary skill in the art would have used these conventional diameters in constructing Sudre’s paper machine clothing. Ex. 1003 ¶¶ 258–261, 263–266; Ex. 1006, 3:64–66.” slip op. at 14

    “review. See 35 U.S.C. § 314 (2018); 37 C.F.R. § 42.4(a) (2023). The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted “unless . . . there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” For the reasons given below, on this record, Petitioner has established a reasonable likelihood that it would prevail in showing the unpatentability of at least one of challenged claims 1–15 of the ’322 patent. Accordingly, we institute an inter partes review of the ’322 patent.” slip op. at 2

Patent Owner does not provide any such assessment in its Preliminary Response. Prelim. Resp. 11.

    “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). Consequently, we determine that Petitioner has shown Verma to disclose limitation [15a] for purposes of institution on the current record.” slip op. at 13
