    “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.” 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. See In re Arunachalam, No. 2016-1607, 2017 WL 4387224, at *2–4 (Fed. Cir. Oct. 3, 2017) (“In light of Dr. Arunachalam’s previous opportunity to litigate the validity of the asserted claims of the ’500 Patent, which contain the [same] terms . . . , we see no reason to allow her to appeal the patentability of the challenged claims of the ’556 Patent, which also contain the same critical terms.”). 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

    “Regarding the interpretation of O’Donnell’s Synacthen test, we do not agree with Patent Owner that the results “lack any significance.” See PO Resp. 20. We are persuaded that one of ordinary skill in the art would understand the results of this test to be an indicator that something was amiss with the O’Donnell Study C patients’ cortisol levels following administration of abiraterone acetate. Results of the Synacthen test led O’Donnell to conclude that further studies were needed to determine whether glucocorticoid replacement would be necessary. Ex. 1003, 2323. We understand Patent Owner’s position that the “Synacthen test results in O’Donnell do not give a complete picture of a patient’s glucocorticoid production.” PO Resp. 21. We, however, do not perceive that a complete picture of a patient’s glucocorticoid production is required for one of ordinary skill in the art to be motivated to explore whether glucocorticoid replacement therapy was necessary. Petitioner’s experts opine that O’Donnell’s results for the Study C patients were “unquestionably abnormal” and implied that abiraterone acetate could result in chronic cortisol deficiency “for which glucocorticoid replacement therapy could be required.” Reply 6– 7 (citing Ex. 1093, 22, 68; Ex. 1023, 1245). We credit this testimony as supporting Petitioner’s argument that one of ordinary skill in the art, upon reviewing O’Donnell’s Synacthen test results and statement regarding impact on adrenal reserve, would not conclude that they lack any significance; rather, they would conclude that they are significant enough to merit further investigation of administration of abiraterone acetate with glucocorticoids.” slip op. at 19

For example, O’Donnell, after evaluating ketoconazole as an agent, turns to an evaluation of abiraterone acetate as a more selective CYP17 inhibitor, i.e., as an improvement on ketoconazole. Ex. 1003, 2318. After presenting the results from its studies, O’Donnell discusses that, in the clinical use of ketoconazole, “it is common practice to administer supplementary hydrocortisone” and that, therefore, “further studies with abiraterone acetate will be required to ascertain if concomitant therapy with glucocorticoid is required on a continuous basis, at times of physiological stress, if patients become symptomatic or indeed at all.” Id. at 2323. This statement represents the proposition that one of ordinary skill in the art would use the example of ketoconazole’s clinical use to take the next investigative steps with abiraterone acetate. We have not been presented with evidence that dissuades us from taking this statement at face value. Patent Owner’s expert testified that ketoconazole, as “an inhibitor of steroid biosynthesis that had been used at that point,” was a basis for comparison: “When you write scientific papers, you always like to make comparisons with what is known and explain why your results are different or the same or what the caveats are. And I think that’s setting up . . . to understand what comes next, why they did this experiment.” Ex. 1188, 169:15–23. Thus, we are persuaded that one of ordinary skill in the art would understand that both ketoconazole and abiraterone are CYP17 inhibitors, albeit with different mechanisms.

    “Regarding Patent Owner’s comparison of abiraterone acetate monotherapy with abiraterone acetate/dexamethasone therapy, we agree with Petitioner that “to the extent that [Patent Owner] tries to draw any conclusion between studies that involve a combination with dexamethasone, we respectfully submit that there’s no nexus there” in that “[d]examethasone is not what’s claimed and there’s no nexus to the claims.” Tr. 19:17–20, 20:2– 3. Although dexamethasone and prednisone are both glucocorticoids, Patent Owner does not point us to satisfactory evidence as to why the ordinary artisan would consider dexamethasone and prednisone to be interchangeable for the purpose of comparing results. Cf. Ex. 2038 ¶ 240 (stating that a person of ordinary skill would “understand the dexamethasone extension study results to be due to a class effect of glucocorticoids” without further citation). Because the claims cover prednisone, and not any other glucocorticoid, the results of the combination of dexamethasone with abiraterone acetate are of limited use, as we are not informed of the similarities or differences of the mechanism of action of those glucocorticoids or how the mechanism leads to the asserted unexpected results. Moreover, to the extent the table purportedly compares the abiraterone acetate monotherapy to abiraterone acetate administered with prednisone, the table compares the abiraterone acetate monotherapy administered in clinical trial COU-AA-001 with the abiraterone acetate administered with prednisone in clinical trial COU-AA-002, without explaining or accounting for the differences between the two trials.

The district court read out of the definition the term “includes.” Id. Although we are not bound by the district court’s reasoning and claim constructions in related proceedings, we do not disregard the determinations of a court interpreting the same claim term in a related patent in a concurrent proceeding.

This statement represents the proposition that one of ordinary skill in the art would use the example of ketoconazole’s clinical use to take the next investigative steps with abiraterone acetate.

    “The Specification teaches the following: The term “sustained release” is defined for purposes of the present invention as the release of the opioid analgesic from the oral dosage form at such a rate that blood (e.g., plasma) concentrations (levels) are maintained within the therapeutic range but below toxic levels over an extended period of time, e.g., from about 12 to about 24 hours as compared to an immediate release product. Preferably the sustained release is sufficient to provide a twice-a-day or a once-a-day formulation. Ex. 1001, 4:56–64. The use of “e.g.” in the above definition for “sustained release” plainly indicates that a 12 to about 24 hour time period is exemplary. Thus, we decline to limit the claim term as Patent Owner would have us do. Rather, we construe “extended release” as “release of the opioid analgesic from the oral dosage form at a rate such that blood (e.g., plasma) concentrations (levels) are maintained within the therapeutic range but below toxic levels over a period of time longer than that of an immediate release of the opioid analgesic.”” slip op. at 11

    “We are not persuaded by Patent Owner’s argument that the lack of specific residency/fellowship training or certification, disqualifies Dr. Vaux from providing opinion testimony on the motivations, understandings, and actions of those of ordinary skill in the art. Dr. Vaux testifies that he is “a medical doctor with specialty training in Pediatrics and Clinical Genetics” and is currently Professor and Clinical Chief of the Division of Medical Genetics in the Department of Medicine at UC San Diego. Ex. 1002 ¶ 1. He also testifies: Since 1994, I have regularly diagnosed and treated patients with urea cycle disorders (“UCD”), and continue to do so today. In treating UCD patients, I regularly prescribe nitrogen scavenging drugs and treat patients who are maintained on therapy with nitrogen scavenging drugs. Ex. 1002 ¶ 1. Thus, Dr. Vaux has actually treated UCD patients for at least five years (a requirement recited by Patent Owner, see PO Resp. 16), including prescribing drugs. Patent Owner does not direct us to evidence that Dr. Vaux’s testimony is untruthful or that his treatment of UCD patients is ineffective, indicating that he does not understand how to treat them. Accordingly, even if Dr. Vaux does not have the specialized certificates or particular training that Patent Owner argues are necessary, he has done the job for over twenty years of one who would carry out the claimed methods.

    “In summary, the ’859 publication teaches that those of skill in the art would have known to use HPN-100 to treat subjects with UCDs. It also teaches that measuring plasma or blood level of ammonia was known to be useful in determining the effectiveness of a drug regimen for a particular patient and that measuring blood ammonia was a known step in adjusting drug dosages.

In addition to the ’859 publication, Petitioner relies on Blau and Simell for the teaching to collect blood from UCD patients after a fast in order to measure plasma ammonia levels. Ex. 1006 at 273 (Table 11.9); Ex. 1005 at 1118; see Pet. 25–26 (citing Ex. 1002 ¶¶ 58, 59); see also id. 1002 ¶ 46, n.2 (citing Ex. 1015 at S11). Anticipating Patent Owner’s argument that Blau relates to diagnosis not treatment of UCDs, Petitioner also cites to Exhibits 1010 and 1015 as evidence that it was generally recommended to measure plasma ammonia after a fast. See Pet. 16, n.2. Exhibit 1010 is a “Lab Update” about measurement in ammonia in blood, and Exhibit 1015 is a publication entitled “Measurement of ammonia in blood.” Both state that most methods recommend collecting a sample from patients who have fasted for at least 6 hours. See Ex. 1010, 4; Ex. 1015, 1. From this evidence, we agree with Petitioner that those of skill in the art would have known that measuring fasting serum ammonia levels, as taught in at least Simell and Blau, was known to be useful with the methods taught in the ’859 publication. In regard to Ground 2, which challenges claim 3 and the claims that depend on it, Petitioner cites Brusilow ’84 for its teaching of measuring a patient’s fasting plasma ammonia level when he or she is admitted, presumably to a hospital, and, in response to elevated levels, treating with the nitrogen scavenging drugs sodium benzoate and phenylacetate.
