Here, however, the challenged claims are directed to methods using a wide range of different types of compounds purported to be “IL-15/IL-15R inhibitors” that are not part of a known or readily identifiable class, do not target the same biological pathway, do not have any common structural features, and do not appear to always function as inhibitors. See Ex. 1018, Abstr., 1575–77, 1579; Ex. 1046, 189:4–19, 191:15–192:15, 193:18–196:22, 198:21–199:21, 197:12–198:19, 200:1–8, 207:11–14, 203:3–10, 207:15–21, 236:12–24; Ex. 1047 ¶¶ 19–23, 56, 63–64, 80–85.

    “598 U.S. at 610. A “specification may call for a reasonable amount of experimentation to make and use a patented invention. What is reasonable in any case will depend on the nature of the invention and the underlying art.” Id. at 613. But the person of ordinary skill in the art cannot be left with merely “a hunting license” or obligated to engage in “painstaking experimentation” or “trial and error” to “see what works.” Id. at 614. Patent Owner argues that “the IL-15/IL-15R inhibitors disclosed in the specification were known in the art and “share the common ‘general quality’ of inhibiting a pathway known to be relevant to and having ‘particular fitness for the particular purposes’ of (id.) treating certain autoimmune diseases by blocking IL-15 signaling.” Sur-reply 14 (citing Ex. 1011, 22; Ex. 2013, 3; Ex. 2017, Abstr.; Ex. 2024, 17; Ex. 2025, 2–3, 6; Ex. 2027, 4; Ex. 2028, 9; Ex. 2029, 4; Ex. 2031, 23; Ex. 2118, 53:22–54:9; Ex. 1018, 1; Ex. 2005, ¶¶ 52–63, 80–83, 130; Ex. 1046, 231:20–25). Patent Owner’s argument is unavailing, however, because the record shows that different IL-15-specific inhibitors may operate in different ways that may result in differential effects, some of which may not include inhibition at all. See Ex. 1047 ¶¶21, 23, 40, 71; Ex. 1018, Abstr., 1576, 1579; Ex. 2013, 4:1– 8; Ex. 2014, 4:9–15; Ex. 2015 ¶ 22; Ex. 2025, 4:34–5:2; Ex. 1046, 166:21– 24, 168:25–169:5, 207:23–209:22, 210:4–17, 210:24–211:6; Ex. 1011, 1:67–2:4; Ex. 2005 ¶¶ 116, 134. Thus, we find that the record supports Drs. Abbas and Plott’s testimony, which we credit, that a person of ordinary skill in the art would be forced to hunt down and test every compound through painstaking Ex. 1002 ¶¶ 85–90, 92; Ex. 1047 ¶ 53 (Dr. Plott’s testimony that the “specification of the ’505 patent is essentially a black box (so far as which aspects of IL-15 signaling it inhibits and how it operates), leaving the reader to guess through trial and error which molecules might operate similarly to ChMBC7 and which do not.”); Ex. 1004 ¶ 61 (Dr. Plott’s testimony that “from the perspective of a clinician, the amount of experimentation required would be extremely burdensome and success would be speculative.”); Ex. 2007, 93:16–97:25, 38:208; Ex. 1046, 234:20–236:11. This is due to the fact that the claims (without limit) encompass any inhibition of any one of the various types of IL-15 signaling and various versions of the receptor, and even implicate other compounds that act on different targets but which inhibit the IL-15 signaling pathway. See Ex. 1047 ¶¶ 10, 53, 68; Ex. 2005 ¶ 71; Ex. 1046, 254:4–255:11, 158:12–160:20. The evidence has shown that IL-15/IL-15R inhibition is complicated and unpredictable, with some inhibitors also capable of enhancing forms of IL-15 signaling rather than preventing it.

  • 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.

  • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

    “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.

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.

Moreover, the preamble of claim 12 recites: “A nutrient formulation for oral ingestion for protecting a user’s eyes from the harmful effect of blue light, the formulation comprising:.” Ex. 1001, 37:13–15.

    “Based on our consideration of the full record, we find that, overall, Patent Owner’s definition is more specifically tailored to the claimed subject matter of the ’883 patent. We also find that, a person with a biomedical engineering degree could have the required background in fluid mechanics. See Ex. 1031, 45:21–46:7. Therefore, we find that a person of ordinary skill in the art would have a B.S. in mechanical or biomedical engineering with at least three years of experience in designing systems for minimally invasive intravascular procedures for treating occluded vessels or the equivalent and in consultation with medical professionals such as interventional neurosurgeons. Although we agree with, and have primarily adopted Patent Owner’s definition for an ordinarily skilled artisan in this proceeding, our analysis and conclusions herein would not change even under Petitioner’s definition. The parties also do not indicate that the outcome would differ based on the definition of the person of ordinary skill in the art. See Pet. 15; PO Resp. 6; Pet. Reply 1.” slip op. at 10

    “as adopted by the Board in the Institution Decision. The ’883 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, 36:18–23 (emphasis added). Moreover, in discussing problems with the prior art systems, the ’883 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 2:62–65. In the ’883 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 ’883 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. 1030 ¶¶ 13–14; Ex. 2001 ¶¶ 53, 62. 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.”” slip op. at 14

    “As discussed above, we construed “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 disclosure from the ’011 provisional application which describes “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,” it 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. 33 (citing Ex. 1003 ¶¶ 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. 34 (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 disclosure of the ’011 provisional application that specifically directs the person of ordinary skill to the portions of these ranges which fall within the ’883 patent’s definition of no “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. 1030 ¶ 29; 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.

See 35 U.S.C. §§ 100(i)(1)(B), 102(a)(2), 102(d)(2); MPEP § 2154.01(b). USPTO guidance also indicates that AIA § 102 prior-art reference effective-filing-date determinations differ from pre-AIA law.

    “As explained in our Institution Decision (Dec. Inst. 5–6), we do not discern a substantive difference between the parties’ respective definitions for the level of ordinary skill in the art. Although Petitioner states a POSITA must have one to two years of postdoctoral research experience and Patent Owner’s definition requires at least five years of “research experience,” Patent Owner’s definition does not indicate a specific time for that research (i.e., it could include research during or after a doctoral program). Neither party addresses or contests the other party’s definition in their post-institution papers. See generally PO Resp.; Pet. Reply; PO Sur-reply. Accordingly, we find the parties’ respective definitions to be equivalent and consistent with the level of ordinary skill in the art as reflected by the prior art in this proceeding. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

    “amount.” Pet. Reply 14. Patent Owner, however, argues that we erred in our construction because the Specification explicitly defines “effective amount” to mean “the amount of herbicide required to achieve at least about 65% phytotoxicity of conventional [i.e., wild, non-mutant] rice (e.g., red rice) in field applications.” PO Resp. 10 (quoting Ex. 1001, 6:34–37). Because the inventors served as their own lexicographers, Patent Owner asserts the Specification’s express definition controls. Id. at 10–11 (citing Martek Biosciences Corp. v. Nutrinova, Inc., 579 F.3d 1363, 1380 (Fed. Cir. 2009) (“When a patentee explicitly defines a claim term in the patent specification, the patentee’s definition controls.”)). Nevertheless, Patent Owner acknowledges that the “less than 10% injury” language “is indeed a limitation of the ’346 Patent claims.” Id. at 11. Having considered the arguments and evidence presented at trial, we agree with Patent Owner that the inventors acted as their own lexicographer to define “effective amount” and that that definition governs its meaning. Phillips, 415 F.3d 1316 (“[O]ur cases recognize that the specification may reveal a special definition given to a claim term by the patentee that differs from the meaning it would otherwise possess. In such cases, the inventor’s lexicography governs.”). We, therefore, construe the term “effective amount” to mean “the amount of an herbicide required to achieve at least about 65% phytotoxicity of conventional rice (e.g., red rice) in field applications.” As explained further below, however, whether incorporated into the construction of “effective amount” or not, the claim language itself further requires that the “effective amount” encompass a specific range of amounts of herbicide (i.e., 14 g AI/Ha to 40 g AI/Ha of quizalofop) and cause “less than 10% injury” to the mutant rice.

    “Mankin would derive the herbicide range suggested by Patent Owner and Dr. Somers from the “rules of thumb,” that range is much broader than the claimed range. Claim 1 recites that the effective amount is 14 g AI/Ha–40 g AI/Ha of quizalofop, but, according to Dr. Somers’s calculations from the Assure II herbicide label, a POSITA would understand the effective amount to be 19.25–154 (or 19.25–184.8) g AI/Ha. Ex. 2036 ¶ 54; PO Resp. 38. Patent Owner does not identify anything in the specification that would allow a POSITA to “immediately discern” the specific range limitations of the claims. See General Hospital, 888 F.3d at 1372. As the Federal Circuit has stated, “one cannot disclose a forest in the original application, and then pick a tree out of the forest and say here is my invention.” Purdue Pharma, 230 F.3d at 1326. Thus, we are not persuaded that the disclosure of a broad range of effective amounts via the Assure II herbicide label coupled with Dr. Somers’s undisclosed “rules of thumb” provide written description support for the narrower range limitations of the claims. Moreover, we agree with Petitioner that Patent Owner is impermissibly working backward from the claimed ranges to determine whether Dr. Somers’s “rules of thumb” can be used to re-create the claimed range from the herbicide label. Pet. Reply 15. That is not the test for written description. Written description “requires a statement of an invention, not an invitation to go on a hunting expedition to patch together after the fact a synthetic definition of an invention.” Indivior UK Ltd. v. Dr. Reddy’s Labs. S.A., 18 F. 4th 1323, 1329 (Fed. Cir. 2021). Accordingly, we are not persuaded that Dr. Somers’s “rules of thumb” applied to the extrinsic herbicide label would be understood by a POSITA as a description in Mankin of the range limitation of the claims. Rather, as Dr. Somers concedes, his “rules of thumb” in conjunction with the herbicide label represent a starting point for a POSITA to test plants to determine what the effective amount range should be. See Ex. 2036 ¶ 53 (referring to a “dose response analysis” between 0.5x and 4x). But “a ‘mere wish or plan’ for obtaining the claimed invention is not sufficient.” See Centocor Ortho Biotech, Inc. v.

    “We are not persuaded. Given the state of the art in 2017, and the known availability of the G2096S seeds at that time, we find the ’346 patent specification enables the claims. The ’346 patent specification clearly describes the G2096S mutant ACCase rice and its use in the claimed method for treating rice. See, e.g., Ex. 1001, 2:37–45, 57:51–61. Contrary to Petitioner’s assertion, the ’346 patent specification has not omitted the G2096S herbicide tolerant rice. Rather, the ’346 patent specification expressly identifies the G2096S mutant rice that possesses the phenotype of tolerance to the effective amounts of herbicides, and describes the method for treating that mutant rice with those effective amounts. See, e.g., id. at 8:8–12; 57:51–61. Thus, we are not persuaded that we erred in relying on Hinga’s seed deposits to determine that Petitioner has failed to meet its burden to prove that the ’346 patent specification fails to enable the challenged claims.

    “labels is akin to relying on literature that clearly provides, on its face, the missing disclosure, as in Falkner. Id. On the contrary, Patent Owner’s argument makes clear that the herbicide labels, by themselves, are insufficient to describe the claimed range limitation. Specifically, because the label ranges do not align with the claimed ranges, Dr. Somers had to make additional assumptions and inferences to support Patent Owner’s written description argument. For example, to calculate the potential effective amount range of herbicides, Dr. Somers applied several different “rules of thumb,” none of which are disclosed in the Mankin specification. See Ex. 2036 ¶¶ 34, 54. According to Dr. Somers, to determine the effective amount for a plant with an unknown response to an herbicide, a POSITA “would naturally test the lowest label (1X) rate of the herbicide, along with a few rates below (starting at about half-X) and above the 1X rate (up to 4X) of the herbicide, to determine the effective dose for this ‘uncharacterized’ plant.” Id. ¶ 34. Dr. Somers refers to this as a “dose response analysis.” Id. ¶ 53. In other words, to determine what the actual effective amount of herbicides should be, Dr. Somers explains that a POSITA would have to test the plants at these “rule of thumb” amounts to determine the effective range. Id. ¶ 34. Given the additional assumptions and inferences that must be made to the herbicide labels to arrive at the range limitations, we are not persuaded that relying on the extrinsic herbicide labels for written description support is proper in this case. That said, even if we were to allow Patent Owner to rely on the herbicide labels and the “rules of thumb” for determining the effective herbicide dose, Patent Owner admits that the ranges calculated from the herbicide labels are broader than the range limitations of the claims. See PO Resp. 39. As Petitioner notes, however, the Mankin Application does not provide any guidance as to whether the effective amount range of herbicide would include a 0.5x dose, a 2x dose, or the 4x dose, such that a POSITA could immediately discern the claimed range from the herbicide label.17 Pet.

    “Dr. Somers, however, relies on the label for Fusilade II, which is a different fluazifop-P-butyl herbicide with a different range of 52.98–103.96 g AI/Ha, which—not surprisingly—aligns more closely with the claimed range of at least 56–150 g AI/Ha. Ex. 2036 ¶ 52. We note that Fusilade II does not appear to be one of the listed herbicides in Table 1, whereas Fusilade DX is. Ex. 2034 ¶ 219 (listing “Fusilade, Fusilade 2000, Fusilade DX, ICI-A 00009, ICI-A 00005, SL-236, IH-773B, TF-1169, and Fusion” as examples of synonyms and trade names for fluazifop-P-butyl). Regardless, that the dose range differs for the same herbicide calls into question the credibility of Dr. Somers’s assertion that a person of ordinary skill in the art would have been able to discern the claimed range limitation by simply looking at the EPA-approved herbicide labels (and applying his “rules of thumb”).18, 19” slip op. at 33

    “We agree with Petitioner that the ’248 patent provides an express definition of “treat” and “treatment.” The Specification states, “[i]n the present text the term ‘treat’ or ‘treatment’ of a pathology means the prophylaxis and/or therapy and/or cure of this pathology.” Ex. 1001, 5:19– 21. This definition includes “cure” as a separate concept from therapy, and further provides that therapy includes “partial or total” alleviation of symptoms. Id. at 5:21–24. The ’248 patent does not define or otherwise describe “treating a coagulopathy” as requiring any specific duration of therapeutic efficacy; therefore, a person of ordinary skill in the art would understand that partial alleviation of symptoms and a shorter duration of therapeutic efficacy is encompassed in “treating a coagulopathy” as recited in claim 1. Claim 16, which depends from claim 1, supports a construction of “treating a coagulopathy” that does not require complete alleviation of symptoms or permanent therapeutic efficacy. Claim 16 recites the “modified FIX polypeptide is expressed at a level that reduces and/or prevents hemorrhages.” Ex. 1001, 46:34–36. Because claim 16 depends from claim 1, this means that “treating a coagulopathy” as recited in claim 1 encompasses merely reducing hemorrhages, i.e., partial alleviation of symptoms. Accordingly, based on the intrinsic evidence, including the express definition of the terms “treat” and “treatment,” we construe “treating a coagulopathy” as prophylaxis and/or therapy and/or cure of the coagulopathy which includes partial alleviation of symptoms, for any duration of therapeutic efficacy.

    “2. Anticipation2 “Under 35 U.S.C. § 102, every limitation of a claim must identically appear in a single prior art reference for it to anticipate the claim.” Gechter v. Davidson, 116 F.3d 1454, 1457 (Fed. Cir. 1997). “[U]nless a reference discloses within the four corners of the document not only all of the 2 As noted above, the pre-AIA provisions of 35 U.S.C. apply to the ’086 patent. the same way as recited in the claim, it cannot be said to prove prior invention of the thing claimed and, thus, cannot anticipate under 35 U.S.C. § 102.” Net MoneyIN, Inc. v.

  • Disclosure Requirements (§112) › Written description (Ariad)Entitled to earlier dateDecided for patent owner

    “Under § 120, a patent is entitled to the priority date of an earlier filed application if (1) the written description of the earlier filed application discloses the invention claimed in the later filed application sufficient to satisfy the requirements of § 112; (2) the applications have at least one common inventor; (3) the later application is filed before the issuance or abandonment of the earlier filed application; and (4) the later application contains a reference to the earlier filed application. In re NTP, Inc., 654 F.3d 1268, 1277 (Fed. Cir. 2011); see also 35 U.S.C. § 120 . As discussed above and in our Decision to Institute, the ’086 patent meets this criterion. While we agree with Petitioner that the face of the ’086 patent does not include a citation of the ‘701 application, the specification does contain a clear claim of priority back to the ’701 application.

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “the art offered by Patent Owner in the ’1795 IPR, which, as noted above, also involved the ’086 patent, should apply to this proceeding, namely “someone with a Ph.D. in biochemistry or similar field in the pharmaceutical sciences, with familiarity and experience with pharmacokinetics.” Pet. 33. Patent Owner does not dispute Petitioner’s definition and, indeed, Patent Owner’s expert, Dr. Amiji, used the same definition in his analysis. Ex. 2014 ¶ 21. For purposes of this Decision, therefore, we adopt Petitioner’s description. We also note that the applied prior art reflects the appropriate level of skill at the time of the claimed invention and supports Petitioner’s definition. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 14

  • Skill levelSkill level patent owner adoptedDecided for patent owner

    “As noted by the Drs. Nordgren and HogenEsch, the differences in these descriptions are “relatively minor.” See Ex. 1038, 238:21–24; Ex. 1039 ¶ 42. Dr. Nordgren explains that even under the higher skill level required by Patent Owner’s description of a POSITA, his opinions would not change. Id. at 1039 ¶ 42. Based upon our review, the differences in Petitioner’s and Patent Owner’s proposed definitions do not impact Petitioner’s grounds for unpatentability or Patent Owner’s responsive arguments. Nor does our consideration of the issues presented turn on which proposed definition is applied. In any event, having considered the evidence and the arguments, we find Patent Owner’s rationale for its more narrow description of the level of ordinary skill in the art to be persuasive and Patent Owner’s description of a person of ordinary skill in the art, while maintaining that the prior art reflects the appropriate level of skill at the time of the claimed invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 10

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

    “In the Patent Owner Response, Patent Owner asserts that Petitioner’s proposed construction is actually a subject matter eligibility argument. PO Resp. 23. According to Patent Owner, “[t]he term ‘porcine circovirus type 3 recombinant protein’ has a plain and ordinary meaning of ‘genetically engineered PCV3 protein.’” Id. (citing Ex. 2052 ¶¶ 91–92). Having considered the positions of both parties, and the evidence of record, we find that for purposes of this Decision, the ordinary and customary meaning of the claim term “porcine circovirus type 3 recombinant protein,” is a PCV3 protein obtained by genetic engineering, and specifically by recombinant technology, wherein the recombinant protein may either have the same structure and same amino acid sequence as variation therein. See Ex. 1026 ¶¶ 217–218; Ex. 1038, 264:2–9, 266:13– 267:3). 2.” slip op. at 12

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed patent owner constructionDecided for patent owner

    “In the Patent Owner Response, Patent Owner asserts that “[a] POSITA would have understood ‘the nucleotide sequence encoding [ORF1, ORF2 or ORF3]’ to mean ‘a nucleotide sequence having at least 90% sequence homology with SEQ ID NOS. 3, 5, or 7 or encoding a sequence having at least 90% sequence homology with SEQ ID NOS. 4, 6 or 8.’” PO Resp. 24 (citing Ex. 2052 ¶¶ 93–96). In support of that position, Patent Owner refers to the following Specification description: [a] preferred PCV3 ORF2 protein is that of SEQ ID NO. 6, but it is understood by those of skill in the art that this sequence, as well as those for ORF1 and ORF3 could vary by as much as 10% in sequence homology and still retain the antigenic characteristics that render it useful in immunogenic compositions. Patent Owner asserts, according to that Specification description, “the sequences described and identified by SEQ ID Nos. in the patent for PCV3 ORF1, ORF2 and ORF3 are representative sequences, and ‘ORF1,’ ‘ORF2’ and ‘ORF3’ in the patent also refers to those sequences with at least 90% sequence homology.” Id. (citing Ex. 2052 ¶ 95; Ex. 2006, 107:9–17). Further, Patent Owner asserts this interpretation is consistent with the language of the other claims. In particular, Patent Owner refers to the limitation in claim 1 reciting that the composition comprises a PCV3 recombinant protein selected from “ORF1, ORF2 and ORF3, wherein said protein is encoded by a nucleotide sequence having at least 90% sequence homology with a sequence selected from the group consisting of SEQ ID NO. 3, SEQ ID NO. 5, SEQ ID NO. 7.” Id. (quoting Ex. 1001, 71:14–21). Having considered the positions of the parties, and the evidence of record, we agree with Patent Owner that the Specification provides clarity and meaning for the use of the terms ORF1, ORF2, and ORF3, which are not set forth or defined in claim 4, from which claim 5 depends, or in claim 5. Petitioner, in its alternative argument regarding the construction of the phrase involving those terms in claim 5, agrees to some extent. See Pet. 26. For purposes of this Decision, and for the reasons discussed by Patent Owner, we construe the claim phrase “nucleotide sequence encoding ORF1, . . . ORF2, and . . . ORF3” recited in claim 5 as meaning “a nucleotide sequence having at least 90% sequence homology with SEQ ID NOS. 3, 5, or 7 or encoding a sequence having at least 90% sequence homology with SEQ ID NOS. 4, 6 or 8.”” slip op. at 13

  • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateUnpatentable

    “We do not find that description to be adequate. Essentially, the Specification description that the sequences for PCV3 ORF 1, 2, and 3, could vary by as much as 10% sequence homology just rephrases what is claimed in terms of those sequences having at least 90% sequence homology, adding only that antigenic characteristics are retained that render it useful for immunogenic compositions. A claim, however, “does not become more descriptive by its repetition,” see Ariad, 598 F.3d at 1350 (quoting Eli Lilly, 119 F.3d at 1568), and “a definition of a useful result rather than a definition of what achieves that result” does not sufficiently Inc. v. Gen-Probe Inc., 323 F.3d 956, 969 (Fed. Cir. 2002)). As noted by Petitioner and Dr. Nordgren, the ’351 patent discloses nucleotide and amino acid sequences corresponding only to the naturally-occurring PCV3 ORFs 1–3. PO Resp. 52; Ex. 1026 ¶ 168. While those sequences may be characterized as “reference” sequences, as they reflect sequences with 100% homology with PCV3 ORFs 1–3, Patent Owner has not demonstrated that they are “representative” sequences for the broad range of sequences claimed. We find that the Specification does not reasonably convey that the inventor made or was otherwise in possession of any of the remaining members of the genus with at least 90% sequence or amino acid homology with ORFs 1–3. PO Resp. 53; Ex. 1026 ¶ 168. We find that Dr. Nordgren credibly characterizes the Specification, as follows: [T]he ’351 Patent outlines a preliminary research plan to eventually make and use the broad range of claimed proteins. That is, the inventor provides a number of DNA and primer sequences that could be used to clone homologous DNA sequences into an expression vector, and theorizes that proteins expressed from sequences having 90% sequence homology will be antigenic. Critically, however, the ’351 Patent does not disclose which of the thousands of different claimed homologous sequences, if any, the inventor possessed, much less had discovered to be antigenic. Instead, the inventor merely proposes, without any factual support, that PCV3-derived amino acid sequences “could vary by as much as 10% in sequence homology and still retain the[ir] antigenic characteristics.” Ex. 1001 at 8:49-56. A POSITA would not credit that unsupported speculation, and therefore would not believe that the inventors possessed such a wide range of proteins.” slip op. at 33
