Patent Owner agrees with Petitioner’s proposed level of skill in the art. PO Resp. 27. We, therefore, apply that skill level in our analysis, with the understanding that the level of skill of art in this proceeding is also reflected in the prior art of record. See Okajima v.

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed petitioner constructionOther

    “We find Petitioner’s proposed construction to be more persuasive based on the ’376 patent specification. 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.” Id. at 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 10cp 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 9

    “Under the doctrine of issue preclusion, also called collateral estoppel, a judgment on the merits in a first suit precludes relitigation in a second [proceeding] of issues actually litigated and determined in the first suit.” In re Freeman, 30 F.3d 1459, 1465 (Fed. Cir. 1994) (citing Lawlor v. National Screen Serv. Corp., 349 U.S. 322, 326 (1955)). The Federal Circuit has articulated a four-factor test in determining whether collateral estoppel attaches: “(1) the identity of the issues in a prior proceeding; (2) the issues were actually litigated; (3) the determination of the issues was necessary to the resulting judgment; and (4) the party defending against preclusion had a full and fair opportunity to litigate the issues.” Levi Strauss & Co. v.

  • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateDecided for petitioner

    “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.10 The 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 9 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. 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. 10 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 Ex. 1001, 6:46–62. We, however, do not address the issue of written description support for any of the subsequently filed applications. 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 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.

  • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element) › Inherent disclosureInherency foundOther

    “We agree with Patent Owner on the legal standard for inherency. As we acknowledged in our Decision, “[i]nherency . . . may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.” MEHL/Biophile Int’l. Corp. v. Milgraum, 192 F.3d 1362, 1365 (Fed. Cir. 1999).” Dec. 14. However, we remain persuaded at this stage of the proceeding on the current factual record based on Hoffbrand 1998 and the Mehta Declaration, that Petitioner established a “reasonable likelihood” that Hoffbrand 1998 necessarily disclosed treatment of patients with “an iron overload condition of the heart” with a therapeutically effective amount of deferiprone. See Dec. 16–20; 35 U.S.C. § 314(a). Patent Owner does not identify a definition of the phrase “iron overload condition of the heart” in the ’328 patent Specification that distinguishes the claimed patient population from Hoffbrand’s disclosure of “10 patients [that] had a liver iron content above 15.0 mg/g dry weight, ie, falling within the range that has been associated with cardiac disease.” Ex. 1007, 297. The reasonable understanding of Hoffbrand’s teaching of this association between liver iron content and cardiac disease is that all ten patients with the elevated iron levels also necessarily fell into the spectrum of having “an iron overload condition of the heart.” Indeed, Patent Owner’s Declarants do not rebut Hoffbrand’s teaching that liver iron content above 15.0 mg/g identifies patients with cardiac disease, and, therefore, with “an iron overload condition of the heart.” Dr. Coates simply notes that Hoffbrand 1998 reports five treated “patients suffered fatal complications. . . . Four of the five reported fatalities resulted from congestive heart failure.” Ex. 2001 ¶ 37. Cf. Pennell Decl. Ex. 2003 ¶ 37. That statement supports the position that Hoffbrand 1998 treated patients who inherently had an ultimately fatal “iron overload condition of the heart” with 75 mg of deferiprone, acknowledged by claim 15 of the ’328 patent as a therapeutically effective amount. Ex. 1007, 295; Ex. 1001, 28:33–37. We recognize that Dr. Pennell stated that “a patient with a liver iron content above 15 mg/g dry weight is at risk of developing cardiac disease not that such liver iron content definitely establishes cardiac disease.” Ex. 2003 ¶¶ 50–51, citing Exhibits 2007, 2015, and 2016. The Exhibits cited by Dr. Pennell do not identify evidence showing a single patient with a liver iron content that exceeds 15.0 mg/g but failed to display an “iron overload condition of the heart.” See Ex. 2003 ¶ 51. Exhibit 2007 states “while whole liver iron levels >15 mg/g dry weight . . . have been shown to predict patients at highest risk of cardiac death, it is not known how these variables relate to cardiac iron deposition.” Ex. 2007, 1. No specific patient data is provided in Exhibit 2007 comparing liver iron levels of particular patients with “iron overload.” See id. Similarly, Exhibits 2015 and 2016 also do not identify any patients with elevated liver iron content >15 mg/g dry weight with normal cardiac iron levels.

    “Regarding the second argument, Dr. Mehta relied upon specific facts within the Olivieri Abstract 1995 itself to support the conclusion that “lower TRT values indicate cardiac disease due to iron overload. Ex. 1010 (Olivieri Abstract 1995).” Ex. 1002 ¶ 75. In particular, Olivieri Abstract 1995 states “MRI demonstrates changes consistent with reduction in cardiac iron in L1 [deferiprone]-treated pts, in who baseline T2 relaxation time (TRT of 23.9±6.4 msec (normal >32) has increased to 32.4±9.3msec.” Ex. 1010. Olivieri Abstract 1995’s identification of the value of “32” as normal for TRT levels with lower values such as “23.9±6.4” as associated with elevated cardiac iron levels that require treatment with deferiprone, provides factual support for Dr. Mehta’s conclusion that patients with these lower TRT values inherently have “an iron overload condition of the heart.” See Ex. 1002 ¶ 75.” slip op. at 6

Bard, Inc., 79 F.3d 1572, 1576 (Fed. Cir. 1996) (holding that the challenger “bore the burden of persuasion . . . on all issues relating to the status of [the asserted reference] as prior art”). However, because Petitioner offered Jin into evidence, which qualifies on its face as prior art under §102(e), Patent Owner bears the burden of producing evidence supporting a date of invention prior to the critical date of Jin. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378–80 (Fed. Cir. 2015). As discussed below, Patent Owner elected to antedate, and thereby remove, Jin as prior art by showing that the inventor actually reduced the claimed invention to practice prior to Jin’s 102(e) priority date(s). As a result, the burden of production returned to Petitioner to demonstrate that the invention set forth in the challenged claims was not actually reduced to practice as of the date alleged. Id. at 1380. In order to establish an inventor’s actual reduction to practice, Patent Owner must show: (1) construction of an embodiment meeting all limitations of the challenged claims; (2) that the invention would work for its intended purpose, and (3) sufficient evidence to corroborate the inventor’s testimony.

    “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.

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).

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.

Specifically, Pink Sheet teaches a dosing method with the MTP inhibitor, implitamide, wherein, as discussed above, the dosing schedule meets the dosing schedule required by claim 1. Ex. 1013. In addition, Pink Sheet discusses MTP inhibitors generally, and notes that they may have efficacy in situations where high-dose statins are ineffective or inadequate, such as homozygous and severe heterozygous familial hypercholesterolemia. Id. Pink Sheet also acknowledges that the toxicity seen with MTP inhibitors may have been due to the high doses used during the clinical trials. Id.

    “based on the complex as a whole, rather than just the carbohydrate component, as Fishbane related to iron dextran complexes. Reply 10. We agree with Petitioner that the language of the term “substantially non-immunogenic carbohydrate component” itself only requires an assessment of the immunogenicity of the carbohydrate component, and disagree with Patent Owner that the claims require an assessment of the immunogenicity of the iron carbohydrate complex as a whole. In that regard, we note that the Specification of the ’702 patent supports our construction that the “substantially non-immunogenic carbohydrate component” is limited to the carbohydrate component as opposed to the iron carbohydrate complex as a whole. Specifically, the Specification teaches in the background section that previously available iron dextran products suffered from a “high incidence of anaphylactoid reactions . . . believed to be caused by the formation of antibodies to the dextran moiety,” while “[o]ther parenteral iron products (e.g., iron sucrose and iron gluconate) do not contain the dextran moiety, and the incidence of anaphylaxis with these products is markedly lower.” Ex. 1001, 1:53–57; see also id. at 11:3‒4 (“non-immunogenic carbohydrate component; no cross reactivity with anti-dextran antibodies”). Moreover, the language of independent claim 1 itself does not require a non-immunogenic complex, but only specifies that the “iron carbohydrate complex has a substantially non-immunogenic carbohydrate component.” Moreover, we decline to limit the term “substantially non- immunogenic carbohydrate complex” to require an incidence level of lower than 0.6%. Rather, what is supported by the claim language and the Specification is a low risk such that the incidence of adverse events of the carbohydrate complex is lower than dextran. See, e.g., Tr. 53‒54 (counsel for Patent Owner acknowledging that Fishbane was not incorporated by reference, and that it was only cited as a “see generally”).” slip op. at 10

  • Skill levelOther

    “We do not find a significant different between the requirements for the ordinary artisan proposed by Petitioner and Patent Owner. We agree with Petitioner (Pet. 14) that the best evidence of the level of skill in the art are the references themselves, see Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001), and, thus, we need not explicitly adopt either Petitioner’s or Patent Owner’s characterization of the level of skill in the art. Moreover, we note that the result of the analysis regarding the patentability of the claims would be the same under the requirements for the ordinary artisan proposed by either Petitioner or Patent Owner.” slip op. at 12

    “Petition (Pet. 22–27), we find that Petitioner has demonstrated by a preponderance of the evidence that Geisser teaches all the limitations of claim 1, either inherently or explicitly. That is, we agree with Petitioner that Geisser teaches a method of treating a disease characterized by an iron deficiency, specifically iron deficiency anemia (Pet. 23; Ex. 1003, Abstract, 1:4‒7, 2:4‒7, 9:30‒31). We further agree that Geisser teaches a method of administering an iron carbohydrate complex, that is, iron carboxymaltose, in a single dosage form of at least 0.6 grams of elemental iron, as Geisser teaches administering iron carbohydrate complexes as a single dose of 500‒ 1000 mg of iron. Pet. 23 (citing Ex. 1003, 1:26‒4:1, 8:7-10, 10:14‒17). In that regard, we credit the testimony of Dr. Linhardt that Geiser discloses iron carboxymaltose, and that Geisser describes a general synthetic method that is nearly identical to the method described in the ʼ702 patent. Ex. 1005 ¶¶ 8‒10, 13. In addition, as Geisser teaches one of the iron carbohydrate complexes explicitly recited by claim 1, that is, iron carboxymaltose, it would inherently meet the limitation that the carbohydrate component is substantially non-immunogenic and would have substantially no cross-reactivity with anti-dextran antibodies. In re Spada, 911 F.2d 705, 708 (Fed. Cir. 1990) (“Products of identical chemical composition can not have mutually exclusive properties.”). The teachings of Geisser support that finding, as Geisser specifically teaches that the complexes have low toxicity and a reduced danger of anaphylactic shock. Pet. 23 (citing Ex. 1003, 1:26‒ 2:1, 8:7‒10); see also Ex. 1001, 12:12‒14 (noting that as “[t]he iron carboxymaltose complex (e.g., VIT-45) generally does not contain dextran and [it] does not react with dextran antibodies.”).” slip op. at 18
