- Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed petitioner constructionDecided for petitioner
“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. Cir. 8 Patent Owner contends that the statement in the ’253 patent regarding the “exemplary embodiment” of “forward flow” is referring to an embodiment in which the volume of the liquid drawn out from the lumen of the catheter is “approximately 0.2 ml.” PO Resp. 40–41 (citing Ex. 1001, 32:35–36; Ex. 1003 ¶ 126; Ex. 2014 ¶ 99). Even if this is correct, the ’011 provisional application does not include the embodiments that the ’253 patent specifically characterizes as being “without the forward flow.” Pet.

“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. 1020 ¶ 29. A POSA would also have practical working knowledge of oncology (Ex. 1020 ¶ 29) and experience with the design of studies necessary for drug development. This description is approximate, and additional experience could make up for less education and vice versa. Ex. 1020 ¶ 29. Pet. 15–16. Patent Owner asserts “that a POSA for purposes of the ’087 Patent would have had at least an M.D. and several years of experience treating patients with hematological malignancies (i.e., blood cancers).” Prelim. Resp. 13. Patent Owner asserts “Petitioner’s definition fails to require experience specific to hematological malignancies or blood cancers. Patent Owners’ definition of a POSA, on the other hand, accounts for the claims’ focus on lymphoma and leukemia.” Id. at 14. At this stage in the proceeding, we find that Patent Owner’s analysis more precisely establishes the level of ordinary skill in the art as it directly relates to those deciding prescribing information based on the prior art reference. See Ex. 1011, 2. The level of ordinary skill in the art usually is evidenced by the prior art references themselves. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“Similarly, here, the Specification consistently states that the invention relates to oral formulations for protecting eye health and that the benefits of carotenoids, such as zeaxanthin and lutein, include the ability to absorb UV and blue light. See, e.g., Ex. 1001, Abstract (“Oral formulations for promoting eye health”), 4:25–31 (stating carotenoids such as zeaxanthin are “very good at absorbing ultraviolet (UV) and blue light”), 15:45–47 (“one object of this invention is to disclose multi-component orally-ingestible formulations for protecting eye health in mammals”). Like the preamble in Proveris, the preamble in claim 12 is the only reference in any of the independent claims to the allegedly inventive concept of protecting eye health from the harmful effects of blue light.

Thus, “the nutrient formulation” and “the user” in the claim body derives antecedent basis from the “nutrient formulation” and “user” that is “defined in greater detail in the preamble.” See Proveris, 739 F.3d at 1373.

The Specification similarly states that embodiments within the scope of the claims have “low immunogenicity,” or are designed to “minimize the potential immunogenicity of the resulting humanized antibody in the clinic.” Id. at 52:54–58, 61:56–61. Moreover, with reference to claim 63 in particular, Patent Owner points to the ’272 application as “explain[ing] that the purpose of humanizing antibodies using its consensus sequence approach is to reduce immunogenicity versus the non-human parent antibody. (Id., 6:24–30, 84:24–30.).” Prelim. Resp. 42 (citing Ex. 2032 (File History for U.S. Patent Application No. 07/715,272 (“the ’272 application”)); see also id. at 38 (indicating that the limitation is satisfied where “[o]nly 1 out of 885 patients experienced an immunogenic response . . . which was a substantial improvement over the murine 4D5 antibody”). In light of the above, we do not alter our prior determination that “[a] humanized antibody which lacks immunogenicity compared to a non-human parent antibody upon repeated administration to a human patient,” refers to a humanized antibody having reduced immunogenicity in a human patient as compared to its non-humanized parent antibody.” slip op. at 14
