“B. PERSON OF ORDINARY SKILL IN THE ART In determining the level of skill in the art, we consider the type of problems encountered in the art, the prior art solutions to those problems, the rapidity with which innovations are made, the sophistication of the technology, and the educational level of active workers in the field. Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986). The level of ordinary skill in the art is “a prism or lens through which . . . the Board views the prior art and claimed invention” to prevent hindsight bias. Okajima v.

“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.

“with regard to claim 17. Nonetheless, we are not persuaded by Petitioner’s contentions. Rather, we find that the ’239 patent contains a sufficient written description of an oral dosage form containing “at least 10% zoledronic acid.” The specification describes a full panoply of zoledronic acid concentrations. Liquid compositions may contain “about 10% (w/v) to about 15% (w/v), about 15% (w/v) to about 20% (w/v), about 20% (w/v) to about 30% (w/v), about 30% (w/v) to about 40% (w/v), or about 40% (w/v) to about 50% (w/v) of zoledronic acid.” Ex. 1003, 10:25–28.

Solid dosage forms also are described as containing zoledronic acid in ranges beginning from “about 10% (w/w) to about 30% (w/w), about 10% (w/w) to about 20% (w/w) . . .” all the way up to a range of “about 80% (w/w) to about 90% (w/w).” Id. at 10:32–39. The breadth of zoledronic acid concentration ranges disclosed is more comprehensive than, and therefore distinguishable from, the more limited concentration ranges disclosed in Wertheim (claimed range of “at least 35%” not supported by disclosure of 25% to 60% range disclosed in priority application). In short, we determine that a person of ordinary skill in the art – a medical doctor with experience treating CRPS – would have recognized that the “inventor invented what is claimed” and did not overreach in claiming “at least 10% zoledronic acid” in an orally administered dosage form for treating CRPS.

In particular, the specification defines “unsuitable for injection” “to mean that one would have substantial difficulty injecting the dosage form (e.g., due to pain upon administration or difficulty pushing the dosage form through a syringe) due to the viscosity imparted on the dosage form, thereby reducing the potential for abuse of the opioid analgesic from the dosage form.” Ex. 1001, 3:15–20. Additionally, in an example concerning the formation of a gel at different concentrations, the specification characterizes certain solutions as “THICK (10 cP to 60 cP): Although a syringe can be filled with this solution, it was hard to do.” Id. at 32:8–24, Table 3. Thus, the specification teaches that a viscosity of at least 10 cP is difficult to pull into a syringe or administer parenterally (via injection). Patent Owner does not address these teachings of the specification. We, therefore, determine that the broadest reasonable interpretation of “unsuitable for parenteral administration” and “unsuitable to pull into an insulin syringe” encompasses a gelling agent that imparts a viscosity of at least 10 cP.” slip op. at 10

Abercrombie & Fitch Trading Co., 719 F.3d 1367, 1371 (Fed. Cir. 2013). Collateral estoppel can attach in proceedings before the Office for identical issues that were addressed with respect to a different patent during prior district court litigation.

All four factors for collateral estoppel are met here. With regard to the first factor, the issue of Joshi’s status as prior art is identical for both proceedings. The ’376 patent is part of the same chain of continuity as the ’888 patent, and both patents share the same specification and claim priority to the same non-provisional application filed August 6, 2002 and provisional application filed August 6, 2001. As such, to the extent Joshi qualifies as prior art to the ’888 patent, it would also qualify as prior art to the ’376 patent.” slip op. at 16

“Although the statements above encompass “mixtures” of HPMC and PEO among a myriad of other possibilities for the gelling agent, we find no basis to conclude that the inventors of the ’376 patent were in possession of the specifically claimed formulation from such a broad disclosure.11 The 10 The April 25th draft application is heavily redacted and we thus cannot discern what other materials were specifically contemplated as “thickening agents” by that time. See Ex. 2091, 5. However, given the nature and amount of the redactions and Patent Owner’s assertion that the draft application ultimately led to the filing of the ’534 provisional with the broad disclosure set forth above, we find it reasonable to conclude that additional materials were included in the draft application. Moreover, the draft application was forwarded as part of an email from Patent Owner’s attorney, which “[e]nclosed the latest draft of the tamper resistant application.” Ex. 2091. As such, there is no evidence to suggest that the list of thickening agents included as part of the draft application originated from the inventors as opposed to patent counsel. 11 We recognize that the same broad disclosure with a “laundry list” of possible gelling agents is found in the specification of the ’376 patent. See Federal Circuit has held that such “laundry list” disclosures are insufficient to satisfy the written description requirement when there is no further guidance (“blazemarks”) provided about which species or combination of species included as part of the list may be selected to arrive at the claimed invention. See Fujikawa v. Wattanasin, 93 F.3d 1559, 1571 (Fed. Cir. 1996). Not having specifically named or mentioned the combination in any manner, “one is left to select[] from the myriads of possibilities encompassed by the broad disclosure, with no guide indicating or directing that this particular selection should be made rather than any of the many others which could also be made.” In re Ruschig, 379 F.2d 990, 995 (CCPA 1967); see also Los Angeles Biomedical Research Inst. at Harbor-UCLA Med. Ctr. v. Eli Lilly & Co., 849 F.3d 1049, 1057 (Fed. Cir. 2017) (“To satisfy the written description requirement, the disclosure in each application must ‘reasonably convey[ ]’ to those skilled in the art that as of the claimed priority date the inventor was in possession of the later claimed subject matter.”) (citing Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 1563 (Fed. Cir. 1991)). Other evidence of record further supports our conclusion that the inventors of the ’376 patent had not conceived of or reduced to practice the claimed formulation prior to Joshi’s August 30, 2001 filing date. In his Declaration, inventor Benjamin Oshlack attests that Patent Owner’s laboratory scientists focused on “testing the syringeability of various concentration solutions of pectin, sodium alginate, and sodium acrylate, as well as combinations of pectin and sodium alginate” between January 4 and Ex. 1001, 6:46–62. We, however, do not address the issue of written description support for any of the subsequently filed applications. 17, 2001. Ex. 2081 ¶ 22. Additionally, Mr. Oshlack attests that the scientists had evaluated “xanthan gum, carrageenan, and locust bean gum (and combinations thereof) as gelling agents, between April 5 and 12, 2001.” Id. ¶ 23. None of the laboratory notebook excerpts proffered by Patent Owner mention a combination of HPMC and PEO as gelling agents to be used in an oxycodone formulation. Exs. 2087–2090. Consistent with the testing actually done, the working examples set forth in the ’534 provisional (as well as in the ’376 patent) focus on xantham gum, pectin, microcrystalline cellulose, and hydroxyethlcellulose as the gelling agents. See Ex. 1026, 44– 49 (Examples 1–5). We find, therefore, that the inventors did not particularly consider either PEO or HPMC, let alone both PEO and HPMC in combination, when evaluating possible gelling agents for an abuse-deterrent formulation of oxycodone. Accordingly, because we find that the ’376 patent is not entitled to a filing date earlier than August 6, 2002, we further determine that Joshi qualifies as § 102(e) prior art as of that date. Having determined that Joshi qualifies as prior art, we turn to the merits of Petitioner’s patentability challenges.” slip op. at 21

“Moreover, “[a]pplicants can define . . . claim scope during prosecution,” just as they can in a patent specification. Teva Pharms. USA, Inc. v. Sandoz, Inc., 789 F.3d 1335, 1343 (Fed. Cir. 2015). Here, during prosecution of the ’419 patent, the applicant stated that “[t]he term ‘hair coloring agent’ refers to a colorant or pigment that is customarily used in hair care products, which changes the color or tone of the hair it is applied to based on visual inspection.” Ex. 1005, 7. To define specific terms used to describe an invention, the applicant need only set out the definition “with reasonable clarity, deliberateness, and precision,” “so as to give one of ordinary skill in the art notice of the change” in meaning. In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994). On the present record, the definition of the term “hair coloring agent” set out in the prosecution history of the ’419 patent is sufficiently clear, deliberate, and precise to give a person of ordinary skill in the art notice that the term is used in the ’419 patent in a manner that does not include substances other than “colorant[s] or pigment[s] that [are] customarily used in hair care products,” even if those other substances might be described as “hair coloring agents” outside the context of the ’419 patent. Ex. 1005, 7. Accordingly, we should give effect to that definition. Because Patent Owner’s proposed construction of “wherein the mixture does not contain a hair coloring agent” gives effect to the prosecution history’s definition of “hair coloring agent,” we adopt Patent Owner’s proposed construction for purposes of the present decision. Thus, on the present record, and for purposes of the present decision, we construe “wherein the mixture does not contain a hair coloring agent” as “wherein the mixture applied to the hair does not have a colorant or pigment that is customarily used in hair care products, which changes the color or tone of the hair it is applied to based on visual inspection.”” slip op. at 6

“In order for claims of the ’703 patent to be entitled to benefit of the filing date of the Provisional, the Provisional must provide written description support for those claims. See 35 U.S.C. § 120. To satisfy the written description requirement of 35 U.S.C. § 112, first paragraph, and provide support for the challenged claims of the ’703 patent under 35 U.S.C. § 120, the Provisional must describe the claimed invention in sufficient detail that one skilled in the art can reasonably conclude that the inventor had possession of the claimed invention. See In re Wertheim, 541 F.2d 257, 261, 262 (CCPA 1976); Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 1563– 64 (Fed. Cir. 1991). The primary consideration in determining whether appropriate written description support exists “is factual and depends on the nature of the invention and the amount of knowledge imparted to those skilled in the art by the disclosure.” Union Oil Co. of Cal. v.

“Because the Provisional provides written description support for the challenged claims, S-1 potentially qualifies as prior art only under 35 U.S.C. § 102(a), but not § 102(b), because the S-1 publication date of September 26, 2003 is less than one year before the filing date of the Provisional of April 9, 2004. As discussed in more detail below, however, Patent Owner has provided evidence that S-1 is not prior art to the claims of the ’703 patent under § 102(a) either because the pertinent portions of the S-1 are the original work of inventors Drs. Blight and Cohen. See 35 U.S.C. § 102(a); Katz, 687 F.2d at 454 (stating “one’s own work is not prior art under sec. 102(a) even though it has been disclosed to the public in a manner or form which otherwise would fall under [sec.] 102(a)”).” slip op. at 37

“We agree with Patent Owner that the Provisional provides adequate written description support for the challenged claims of the ’703 patent. We agree with Drs. Lublin and Peck and credit their testimony that one of skill in art reading the Study Design schematic for Example 11 would have understood that a patient in the 10 mg b.i.d. arm of the study would have received 10 mg b.i.d. throughout the two-week upward titration period. As 10 mg b.i.d. is the lowest dose except for placebo, we find that it necessarily 30 follows that those patients in the 10 mg b.i.d. arm of the study do not need upward titration to the treatment dose because they start and finish at the lower 10 mg dose.” slip op. at 30

“Although the burden of persuasion for unpatentability never shifts from Petitioner during the trial, the burden of production may shift. See Dynamic Drinkware, 800 F.2d at 1379. Petitioner adequately met its burden of production by presenting S-1 as prior art that on its face lists authors that differ from the inventors of the patents at issue. See Ex. 1003, 92. Patent Owner has responded with ample and persuasive evidence, however, that Drs. Blight and Cohen are the sole source of the disclosure of S-1. Thus, Patent Owner satisfies any burden of production to refute Petitioner’s case that S-1 is prior art under 35 U.S.C. § 102(a). See supra. Petitioner’s response to Patent Owner’s evidence does not persuade us that the portions of S-1 upon which they rely are not solely attributable to Drs. Blight and Cohen. Specifically, Petitioner offers evidence from the S-1 of a statement that the MS-F202 clinical trial was designed “after extensive consultation with a panel of expert MS neurologists and with the FDA,” arguing that statement indicates that Drs. Blight and Cohen may not be the sole authors 41 of the protocol for this clinical trial. Reply 2. Petitioner further argues that Drs. Blight and Cohen’s deposition testimony supports its contention that Drs. Blight and Cohen may not be the sole authors of the protocol for this clinical trial because they could not recall the details of that consultation. Id. at 3 (citing Ex. 1064, 64:18–65:14; Ex. 1063, 76:20–77:20, 80:9–81:14, 110:13–111:2). Petitioner also takes issue with another statement in S-1 indicating that in early 2002, Drs. Blight and Cohen drafted descriptions of the MS-F201 and MS-F202, although version 1.0 of the MS-F202 protocol is dated October 2002. Id. at 2 (citing Paper 28, 16; Ex. 2050, 6). Finally, Petitioner points to publications discussing MS-F201 and MS-F202 where Drs. Blight and Cohen are not consistently named as authors and other authors, such as Drs. Goodman and Katz, are listed. Id. at 3–4. We find that Petitioner’s evidence that allegedly casts doubt on the authorship of the relevant portions of S-1 is not sufficient to overcome the ample, unequivocal evidence presented by Patent Owner that supports our finding that the relevant portions of S-1 are the original work of Drs. Blight and Cohen alone. See In re Katz, 687 F.2d at 455. Both Drs. Cohen and Blight state that they alone are the inventors and sole originators of the work in S-1 upon which Petitioner relies. See Exs. 2044, 2045. Five other declarants, intimately involved in the development of S-1, two of which now work for entities other than Acorda, substantiate this testimony. See Exs. 2046–2048, 2052, 2056. Relying on statements that may, on their face,” slip op. at 41
