“POSA helpful. Moreover, Patent Owner’s definition appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosure of the ’434 patent. We do not see a need to specify that the POSA would have experience studying the role of CGRP in migraine. Accordingly, for purposes of this Decision, we accept Patent Owner’s proposed definition of the person of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“the prior art itself [may] reflect[] an appropriate level” as evidence of the ordinary level of skill in the art) (quoting Litton Indus. Prods., Inc. v. Solid State Sys.

“Petitioner relies upon for its asserted combination of references. The rHSA exemplified in Hatsuyama’s Reference Example 1 and described in Table 1 is produced in and purified from yeast according to methods described in other publications not cited or relied upon in the Petition. Ex. 1004 ¶ 69. The Petition does not address those methodologies or suggest that it would have been obvious to employ them in combination with Deeter. Rather, Petitioner alleges that it would have been obvious to substitute the yeast-derived rHSA exemplified in Hatsuyama with Deeter’s rHSA, which is produced in rice and purified according to a different process. See Ex. 1005 ¶¶ 116–117. Petitioner has not demonstrated that a POSA would have understood Deeter’s rice-derived rHSA to have the same properties as the yeast-derived rHSA in Hatsuyama’s Table 1. Indeed, the data in the Specification of the ’389 patent shows that Deeter’s rHSA had substantially higher levels of endotoxin than the rHSA in Hatsuyama’s Table 1.

“In general, “a preamble is not limiting where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.” Catalina, 289 F.3d at 808 (quotation marks omitted). But even then, “[w]hether a preamble stating the purpose and context of the invention constitutes a limitation of the claimed process is determined on the facts of each case in light of the overall form of the claim, and the invention as described in the specification and illuminated in the prosecution history.” Applied Materials, Inc. v. Advanced Semiconductor Materials Am., Inc., 98 F.3d 1563, 1572–73 (Fed. Cir. 1996). We determine that, read in view of the Specification, the preamble, even though it states an intended purpose, is limiting, because “it is necessary to give life, meaning, and vitality to the claim.” See Catalina, 289 F.3d at 808 (quotation marks omitted). The ’308 patent discloses “an adoptive cellular immunotherapy composition comprising a genetically modified helper T lymphocyte cell [i.e., CD4+ T cell] preparation that augments the genetically modified cytotoxic T lymphocyte cell [i.e., CD8+ T cell] preparation[’]s ability to mediate a cellular immune response.” Ex. 1001, 9:4–8, see also id. at 9:36–42 (disclosing that in some embodiments, an adoptive cellular immunotherapy composition “comprises an antigen-reactive chimeric antigen receptor modified naïve CD4+ T helper cell that augments the CD8+ immune response.”), 9:48–51 (the same).

Under this construction, Petitioner argues, the CD4+ T cells recited in claim 1 can be surface positive for CD62L, for CD45RA, or both. Id. (citing Ex. 1002 ¶ 87). And because CD62L+ can be either TN or TCM cells, Petitioner contends “claim 1’s CAR-modified CD4+ T cells can be either majority TCM or TN.” Id. at 17 (citing Ex. 1002 ¶¶ 62–66).

“as adopted by the Board in the Institution Decision. The ’253 patent explicitly defines this term, stating: The term “forward flow” is used herein to define an amount of liquid in the lumen 662 that exits the distal end 664 in a distal direction. Forward flow is defined as greater than 6 microliters of fluid (approximately 1 mm of catheter length of ID 0.071″=5.7 μL). Ex. 1001, 38:18–23 (emphasis added). Moreover, in discussing problems with the prior art systems, the ’253 patent states that “[w]hen positive pressure exists at the distal end of the lumen, liquid from inside the lumen exits out from the distal end of the catheter in a distal direction. This is referred to as forward flow.” Id. at 3:8–11. In the ’253 patent, the patentee acted as its own lexicographer as evidenced by usage of language such as “is used herein to define,” “is defined,” and “is referred to as,” to discuss “forward flow.” We find that the definition of “forward flow” in the ’253 patent specification would provide a person of ordinary skill with “reasonable clarity, deliberateness, and precision” as to the meaning of the term. See Paulsen, 30 F.3d at 1480; see also Ex. 1034 ¶¶ 13–14. Thus, we construe the term, “forward flow,” to mean “an amount of liquid in the lumen that exits the distal end in the distal direction that is greater than 6 microliters.” We disagree with Patent Owner’s contention that our construction imports limitations from a single embodiment into the claims. As explained above, the ’253 patent clearly defines the term “forward flow” and this definition is not limited to a single embodiment. In fact, the ’253 patent indicates that, while “[f]orward flow is defined as greater than 6 microliters of fluid . . . [l]ess forward flow is also included in this definition.” Ex. 1001, 38:21–24. The ’253 patent specifies that “the amount of forward flow can be restricted to no greater than 2 microliters or, in a particularly beneficial embodiment, forward flow is approximately zero microliters.” Id. at 38:24– 29. This language indicates that our construction encompasses multiple embodiments from the ’253 patent. We also disagree with Patent’s Owner’s proposed construction of “forward flow” because it is not supported by the ’253 patent specification. Patent Owner contends that “there is ‘no forward flow’ until the full extent of the distal portion” exits the distal end and thus forward flow is prevented when only less than “the full extent of the distal portion” exits the distal end. PO Resp. 9 (emphasis omitted). To adopt Patent Owner’s proposed construction, we would have to essentially ignore the ’253 patent’s express definition of this term. Further, there is no support in the ’253 patent specification for “full extent” or “fully exiting.” We also agree with Petitioner that Patent Owner’s construction effectively eliminates the concept of preventing forward flow because, as Patent Owner acknowledges, it could allow, for example, 20 milliliters of fluid to exit the catheter, which could displace the thrombus into the patient’s vasculature, a problem that the ’253 patent seeks to avoid.

“As discussed above, we construe “forward flow” to mean “an amount of liquid in the lumen that exits the distal end in the distal direction that is greater than 6 microliters.” Thus, for the ’011 provisional to provide support for this limitation, the provisional must demonstrate that the inventors had possession of preventing greater than 6 microliters of fluid out of the distal end of the catheter. While Patent Owner points to disclosures from the ’011 provisional application that describe the desire to have “a minimal amount of momentum transfer from the fluid column to the stuck clot to unstick the clot sufficiently” and “[t]he exiting movement of fluid [being] limited to a specific volume and/or pressure and is automatically and precisely controlled” to prevent the “possibility of overshooting,” these disclosures would not convey to one of ordinary skill in the art that the inventors were in possession of a device that limited forward flow to no greater than 6 microliters of fluid. PO Resp. 35 (citing Ex. 1003 ¶¶ 15, 16, 138). Patent Owner also contends that the ’011 provisional application provides “multiple examples of liquid flow exiting the distal end of the catheter such that no forward flow occurs, such as 1 microliter or 0.5 mm of column shift.” PO Resp. 36–37 (citing Ex. 1003 ¶ 91). However, the disclosure cited by Patent Owner provides ranges of liquid flow of “approximately 0.001 ml to approximately 1.0 ml, in particular, approximately 0.1 ml to approximately 0.5 ml” and exemplary length of shift distances of “approximately 0.5 mm to approximately 30 mm, in particular, approximately 0.5 mm to approximately 15 mm.” Ex. 1003 ¶ 91. There is nothing in the ’011 provisional application that specifically directs the person of ordinary skill to the portions of these ranges that fall within the ’253 patent’s definition of “forward flow” (i.e., no greater than 6 microliters of fluid). In fact, the majority of the cited ranges are greater than 6 microliters, going all the way up to 1,000 microliters, such that there would be forward flow in these examples. See Ex. 1034 ¶ 25; Purdue Pharma, 230 F.3d at 1326–27 (“[O]ne cannot disclose a forest in the original application, and then later pick a tree out of the forest and say here is my invention. In order to satisfy the written description requirement, the blaze marks directing the skilled artisan to that tree must be in the originally filed disclosure.”); Fujikawa v. Wattanasin, 93 F.3d 1559, 1571 (Fed. Cir. 1996). Further, we note that the ’253 patent differentiates between embodiments that allow forward flow and embodiments in which no forward flow occurs. See Ex. 1001, 32:58–60, 37:19–22; Pet. Reply 10–11. For example, the ’253 patent describes an embodiment in which the “momentum causes a small amount of fluid to move through the distal portion of the catheter [] and create a small distal movement of the clot.” Ex. 1001, 32:47– 51. This same embodiment is disclosed in the ’011 provisional application. Compare Ex. 1003 ¶ 126 with Ex. 1001, 32:16–60. The ’253 patent describes this disclosure as an “exemplary embodiment” in which the “flow of fluid forward . . . is intentional, which is in contrast to other exemplary embodiments herein where substantially no forward flow occurs.” Ex. 1001, 32:57–60; see also, id. at 37:19–22 (“Turning now to embodiments . . . without the forward flow”).8 The ’011 provisional application does not include the subsequent embodiments from the ’253 patent that are described as being “without the forward flow.” See Ex. 1005 ¶ 68; Ex. 1034 ¶¶ 22–23. This further demonstrates that the ’011 provisional application does not support the limitation of “prevent[ing] forward flow.” We also note that the ’011 provisional application does not contain adequate support for the limitation of “substantially prevent[ing] forward flow” even under Patent Owner’s proposed construction. While the ’011 provisional discloses “controlling the distal movement of the fluid column” (Ex. 1003 ¶¶ 15, 16), this does not support Patent Owner’s assertion that the ’011 provisional teaches that “the distal portion of the fluid column is substantially prevented from fully exiting the distal end.” PO Resp. 35–36. For example, as discussed above, the ’011 provisional application discloses permitting distal flow of up to 1,000 microliters, which would likely exceed the amount that could be characterized as the full distal portion. Ex. 1003 ¶ 91; Ex. 1034 ¶ 25. Thus, we find that the ’011 provisional application does not “clearly allow persons of ordinary skill in the art to recognize that [the inventors] invented what is claimed.” In re Gosteli, 872 F.2d 1008, 1012 (Fed. Cir. 1989); Lockwood v. American Airlines, Inc., 107 F.3d 1565, 1572 (Fed.

“Based on the above, we determine that, for prior-art determinations under AIA § 102, “there is no need to evaluate whether any claim of [a reference] patent document is actually entitled to priority or benefit under 35 U.S.C. 119, 120.” MPEP § 2154.01(b) (emphasis added). Rather, under the AIA, a reference patent document need only meet the “ministerial requirements” of §§ 119 and 120, and the provisional or other earlier application(s) to which the reference patent document claims a right of priority must “describe[] the subject matter” relied upon in the reference patent document as prior art. 35 U.S.C. § 102(d)(2). Patent Owner has not contested that Teigen meets the procedural requirements for claiming priority to the ’712 patent or the ’095 PCT application. Teigen also appears to meet the ministerial requirements for claiming priority to the provisional applications because it properly claims the benefit of these applications, the ’095 PCT application was filed co-pending with the provisional applications, and the applications share common inventors. Ex. 1007, codes (22), (60), (63), (72); Ex.1008, 2; Ex. 1009, 2; Ex. 2005, codes (22), (30), (72). Patent Owner does not dispute that Teigen meets the “ministerial requirements” of § 119. Because we find that the Dynamic Drinkware analysis does not apply here, we agree with Petitioner and Patent Owner, that we need not reach the issue of whether a claim from Teigen is supported by either Teigen provisional application.

This claim language makes clear that the recited “gRNA functionality” requires a molecule that can: (1) associate with a Cas protein, and (2) target that complex to a target sequence in a polynucleotide. To the extent Petitioner suggests that a gRNA “need only bind to the Cas protein” to have “gRNA functionality,” we disagree because the claims additionally recite the above-quoted targeting functionality. See Reply 16 (emphasis added). At the same time, we agree with Petitioner that “a gRNA need not cleave the target DNA” to have the claimed “gRNA functionality.” Reply 16. The Specification defines “gRNA functionality” as “one or more functions of naturally occurring guide RNA, such as associating with a Cas protein, or a function performed by the guide RNA in association with a Cas protein” and lists various gRNA functions, e.g., “associating,” “targeting,” “binding,” “nicking,” and “cleaving,” that may be present “in certain embodiments” of the invention. Ex. 1001, 6:56–7:1. However, as noted above, the claims recite “gRNA functionality comprising” only the associating and targeting functions. Thus, while a molecule may have additional functions such as cleaving a target polynucleotide, it need only exhibit the recited “associating” and “targeting” functions to have the “gRNA functionality” in claims 1 and 19. Our determination that “gRNA functionality” requires the recited “associating” and “targeting” functions, but not additional, unrecited functions such as cleaving, is also consistent with the parties’ position that the claim language has its plain and ordinary meaning.

“III. MOTIONS Motion to Strike (Paper 50) Petitioner filed a motion to strike portions of Patent Owner’s Sur- Reply. Paper 50. Patent Owner opposes the motion. Paper 53. Petitioner contends Patent Owner raised new argument about Exhibit 1014 (a paper authored by Dr. Patterson), which was submitted with the filing of the Petition but only cited by Patent Owner for the first time in its Sur-Reply. Paper 50, 1–3; PO Sur-Reply 14 (citing Ex. 1014). According to Petitioner, Patent Owner presents new argument about the reversibility of certain crosslinks caused by formaldehyde, cites new experimental data (in Ex. 1014, Fig. 2.1), and argues such matters would have been known before any possible priority date of the ’277 patent. Paper 50, 1–3. Moreover, Petitioner argues, the untimeliness of Patent Owner’s arguments about Exhibit 1014 prevented the exhibit’s author, Dr. Patterson, from addressing them to provide explanation or context. Id. at 2–3. For the reasons given below, we deny Petitioner’s motion to strike. First, we find that Patent Owner’s arguments on Exhibit 1014 are, on balance, responsive to issues raised by Petitioner in its Reply. It is true that Petitioner submitted Exhibit 1014 with its Petition and that Patent Owner did not cite it until its Sur-Reply. However, the points raised by Patent Owner about Exhibit 1014 respond to certain of Petitioner’s arguments raised for the first time in its Reply. For example, Petitioner argued a POSA would not have been concerned about formaldehyde’s use (such as cross-linking disclosed in Heinmoller that Patent Owner cited in its Response) and that those concerns arose only after the supposed priority date of the ’277 patent. 88 Pet. Reply 8–9. Patent Owner’s citation of Exhibit 1014 is responsive on such points (e.g., it discusses cross-linking with formaldehyde’s use), it published in 2000 and is thus earlier than some references Petitioner argued were too late to evidence a POSA’s knowledge, and, lastly, it was authored by Dr. Patterson and arguably called into question the credibility of rebuttal opinions he offered about the state of a POSA’s knowledge on such issues. Second, Exhibit 1014 does not, ultimately, help Patent Owner as we do not rely on the portions of Exhibit 1014 cited by Patent Owner or Patent Owner’s argument about them. As discussed in our analysis, if cross-linking (as reported in Heinmoller or, for that matter, Exhibit 1014) was a perceived problem, Dr. Patterson provides a credible explanation how it could be and likely was addressed by Pertl.54 Supra Section II(G)(3) (citing Ex. 1047).” slip op. at 88
