“Specification of the ’345 patent supports an understanding that some activity is required for a polypeptide to be a “modified PH20 polypeptide,” and it is the enzymatic activity of hyaluronidase specifically that is the most frequently identified activity recited in the Definitions section of the ’345 patent. Indeed, the definitions of “PH20” and “modified PH20 polypeptide” both require hyaluronidase activity. See Ex. 1001, 44:20–21, 49:4–7 (“PH20 refers to a type of hyaluronidase that . . . is neutral-active” and “neutral active refers to the ability . . . to enzymatically catalyze the cleavage of hyaluronic acid at neutral pH”); 47:8–11 (“A modified PH20 polypeptide can have up to 150 amino acid replacements so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity.”). Similar language is used later in the definition of a “conjugate” to explain that even when the modified PH20 polypeptide is linked to another polypeptide or chemical moiety it “retains hyaluronidase activity.” Id. at 61:60–67. In contrast, the discussion regarding the potential use of “modified PH20 polypeptides that are inactive” as antigens in contraception vaccines appears only in non-definitional sections of the ’345 patent. Id. at 71:16-18, 74:11–13. Accordingly, we find that this disclosure does not modify the definition’s explicit requirement that the claimed “modified PH20 polypeptide” exhibit hyaluronidase activity. Id. at 47:3–11.” slip op. at 20

“description (see Capon, 418 F.3d at 1357–58), Patent Owner is trying to extend that to include that which is at most obvious from the prior art, as opposed to what is actually described. That is, it may have been obvious to a POSA to align PH20 sequences with other known hyaluronidase enzymes and to use the crystal structure of a different hyaluronidase (Hyal-1) in SWISS-MODEL to generate a three-dimensional structure, but none of that is described in the common disclosure itself. “[A] description that merely renders the invention obvious does not satisfy the [written description] requirement.” Ariad, 598 F.3d at 1352. While a POSA might be able to embark on their own research program to try to find suitable multiply-modified PH20 polypeptides, the four corners of the written description do not demonstrate possession of such. See id. at 1356‒57 (recognizing that “[p]erhaps one of ordinary skill could discover this information, but this does not alter our conclusion that the description . . . just represent[s] a wish or arguably a plan for future research”) (internal quotation omitted).” slip op. at 66

“instances of epistasis are “rare” and an inactive PH20 polypeptide “will stay inactive . . . absent intentional ‘rescue’ mutations.” See Sur-reply 12–14. But the claims encompass far more than combinations of just two substitutions, and even Dr. Petsko concedes there are “billions” of sequences within the recited sequence space that will not properly fold. See Ex. 2070 ¶ 347; see also Ex. 1133 ¶ 237 (“While some [residues critical to protein structure] can be predicted (e.g., highly conserved positions), many others cannot without experimentation.”).

“At the outset, we note that the claim language requires only that “the first seat and the second seat” be arranged in an inline descending configuration, not that the seat’s mounting points or other physical connections be so arranged. Ex. 1010, 17:31–33. Baby Jogger improperly reads “seats” out of the claim and substitutes the seat’s “mounting points” on the frame. A proper reading of the claim language focuses on what happens when both seats are connected to the frame, not where they are so connected. In other words, “when connected to the frame” simply emphasizes that both seats must be connected to the frame to form the inline descending configuration, as opposed to the single stroller embodiment of Figure 1, where there cannot be an inline descending configuration because only one seat is connected to the frame and the other seat is removed, i.e., not connected to the frame. That reading is supported by the specification of the ’682 patent,” slip op. at 9

The relevant inquiry is whether the disclosure of the prior application “convey[s] with reasonable clarity to those skilled in the art that, as of the filing date sought, the inventor was in possession of the invention.” PowerOasis, 522 F.3d at 1306 (emphasis in original; citation omitted). “While a prior application need not contain precisely the same words as are found in the asserted claims, . . . the prior application must indicate to a person skilled in the art that the inventor was ‘in possession’ of the invention as later claimed.” Id.

“Instead, Evenflo’s argument rests on isolating the statement—“A similar sub-frame arrangement is disclosed in [Offord ’797]”—from the remainder of the passage in which that statement appears in order to arrive at a reason to incorporate the reversibility teaching of Offord ’797. However, when that statement is read in the context of the full passage in which it appears, nowhere does that passage suggest reversibility as the reason for referencing Offord ’797. More accurately, it suggests a different reason that relates to a curved lug 108 by which sub-frame 100 rests on the stroller’s main frame 4 to carry the weight of the stroller’s two occupants— When the interface components 100 are attached to the frame assembly 4 they form a sub-frame of the frame assembly 4, and when the child-carrying units are mounted thereon, one behind the other, they are in a compact echelon formation, one of the connector sockets 106 of each component 100 being at a higher level in relation to the ground than the other connector sockets 106. The higher connector socket 106 and further connecting leg 102 are both connected to the respective opposite ends of an upper mounting piece 107. In addition, on the inner side of the lower connector sockets 106 there is a downwardly curved lug 108 which serves to rest upon a part of the basket frame 44, such that the weight of two infants is fully supported by the frame assembly 4. A similar sub-frame arrangement is disclosed in [Offord ’797]. Ex. 1051, 9:23–36 (emphasis added). That passage shows that, rather than reversibility of the sub-frame, the reference to Offord ’797 is more aptly directing the reader to the arrangement and details of a similarly curved lug structure in the stroller sub-frame of Offord ’797. Indeed, Figures 5 and 6 of Offord ’797, reproduced below, disclose just such a curved lug in the context of “corner pieces 20” having “channel 21.” Ex. 1054, 4:10–23.” slip op. at 53

“that Boerjes alone teaches or suggests limitation 1(h) by a preponderance of the evidence. Although the Petition is persuasive that Boerjes allows a user to “identify areas that need replacing, such as ‘a margin line’ to be removed, ‘areas of poor margin preparation,’ and ‘holes or areas of incomplete scan[s],’” and that the user can identify regions of a prepared tooth surface requiring additional preparations and “supplemental scanning” (Pet. 32 (citing Ex. 1004 ¶¶ 189, 193, 196)), Boerjes is silent with respect to replacing at least a portion of the removed surface portion of the model using the received second scan data of the patient’s teeth, per claim 1. Boerjes certainly contemplates the re-scanning of the dentition, but does not assert partial insertion of new data into an existing 3D model. We acknowledge that Petitioner has argued (Pet. 43–44) that Boerjes’ Figure 4 and paragraph 144 of Boerjes teach partial replacement, but we are persuaded that those disclosures suggest total replacement and not partial replacement. The reference to “supplemented or replaced with new scan data” (Ex. 1004 ¶ 199) does not necessarily teach or suggest partial scanning, as Petitioner has argued. Additionally, Petitioner has argued (Pet. “combining historical three-dimensional data” (quoting Ex. 1004 ¶¶ 139, 144, 163), would have suggested to ordinarily skilled artisans that “Boerjes would be used to replace at least a portion of the model with the new scan data. Id. at 45 (citing Ex. 1003 ¶ 112). These disclosures are, however, applicable to scans that create complete replacement as well as partial replacement. We remain persuaded that Boerjes does not teach partial scans used to obtain partial replacement. Even under the “comprising” language of claim 1, for example, the complete replacement of a 3D model cannot teach or suggest “replacing at least a portion of the removed surface portion” without repudiating the language of the claim by making a portion be the entire model. Even if, as Petitioner asserts, “removing portions of a virtual model has been a well-known and routine technique in 3D modeling,” and the “process of replacing a user-identified portion would have been well within the skills of a POSITA” (Pet. 35), the disclosure of Boerjes does not teach or suggest such processes. Although Boerjes allows for the possibility that portions of a model can be identified as needing replacement or supplementation, it does not disclose the partial replacement required by the instant, independent claims. Boerjes’s actual disclosure details that supplemental scanning is used to compensate for an inadequate scan, but such supplemental scanning is not disclosed to be used to stitch together before-and-after models that have undergone an intervening physical change.” slip op. at 15

“We disagree with Patent Owner that a person of ordinary skill in the art would have understood that limitation 1.2 must be performed before limitations 1.3 or 1.4. See Ex. 1001, 35:21–24. See Interactive Gift Exp., Inc. v. Compuserve Inc., 256 F.3d 1323, 1342 (Fed. Cir. 2001) (“Unless the steps of a method actually recite an order, the steps are not ordinarily construed to require one.” (citing Loral Fairchild Corp. v. Sony Corp., 181 F.3d 1313, 1322 (Fed. Cir. 1999)). The evidence suggests that a “target printer” is any printer that is ultimately selected for fabricating the object, and such a printer could send its configuration information either before or after that determination is made in limitation 1.2. This interpretation does not render the word “target” meaningless. At some point, a printer must be determined to be the target printer, which is the one intended to ultimately fabricate the three-dimensional object. But the target printer still exists, and is capable of being queried, before that determination is made. We find the examples in the ’774 patent pertinent to this question. The ’774 patent states that “the target printer may include more than one printer.” Ex. 1001, 18:66–67. In discussing the step of “query target printer for properties 306” (Fig. 3A), the ’774 patent states that “[i]n one aspect, numerous queries are sent to numerous printers, e.g., for use in selecting one or more of the printers as the target printer.” Id. at 19:8–10. Alternatively, “the query is sent to a printer that is not necessarily the target printer as described herein, e.g., when the query or information received from a response to the query is used for the selection of the target printer.” Id. at 19:11–14. Importantly, the second embodiment states that the queried printer “is not necessarily the target printer,” suggesting that the queried printer could be the target printer even before it is determined to be such. Id. at 19:11–12 (emphasis added). Based on the evidence of record, a person of ordinary skill in the art would have understood that the “target printer” can be determined after the query recited in limitation 1.3 or the reception of configuration information recited in limitation 1.4. Thus, the evidence does not impose an ordering between limitations 1.2 and 1.3 or between limitations 1.2 and 1.4. The evidence also does not support Patent Owner’s argument that the two reverse-order examples in the ’774 patent are unclaimed embodiments.” slip op. at 10

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”).” slip op. at 29

“exclude the use of modified PH20 polypeptides as contraceptives—the only other possible utility described in the ’652 patent—is unavailing. Resp. 39. First, “[t]he fact that a patent asserts that an invention achieves several objectives does not require that each of the claims be construed as limited to structures that are capable of achieving all of the objectives.” Phillips, 415 F.3d at 1327 (citing Liebel–Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 908 (Fed. Cir. 2004)). Second, unlike the definitions of “PH20” and “modified PH20 polypeptide” in the “Definitions” section of the Specification, the passages describing possible contraceptive use do not contain any characteristics suggesting they are definitional in nature. See Alnylam, 138 F.4th at 133 (enumerating “characteristics” such as the fact that the text appears in the “Definitions” section, sets the term off in quotation marks, and uses phrases like “refer to” that indicate that specification language is definitional in nature). Accordingly, the statement that “[a]lso provided are modified PH20 polypeptides that are inactive, and that can be used, for example, as antigens in contraception vaccines” (Ex. 1001, 75:56–58), does not redefine the term, nor otherwise void the definitional language in the Specification stating that a “modified PH20 polypeptide can have up to 150 amino acid replacements, so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity.” Id. at 48:47–49 (emphasis added).” slip op. at 26
