    “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 may contain “at least about 10% (w/w), at least about 20% (w/w) . . .” up to “at least about 80% [w/w]” zoledronic acid. Id. at 10:30–32. 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 Unocal, the original disclosure explicitly described the effects of altering the variables, explicitly described the claimed endpoints as preferred, or explicitly recited them in an original claim. Moreover, persuasive expert testimony was offered to support the finding that the specification reasonably conveyed to one skilled in the relevant art that the inventor possessed the later claimed invention. Unocal, 208 F.3d at 993, 998–99. In Wertheim, the CCPA held that the specification supported the claimed range of 35–60% where the specification described the range of 25–60% along with specific embodiments of 36% and 50%. 541 F.2d at 264–65. In this case, the ’239 patent specification does not clearly allow persons of ordinary skill in the art to recognize the “about 80 mg” endpoint as part of invention described in the ’239 patent.

    “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

    “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.

    “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

Ex. 1003, 2318; Ex. 1005, Table 1. 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. With this knowledge, and given the teachings of the prior art on administration of ketoconazole and administration of abiraterone acetate, we find that one of ordinary skill in the art would look to the administration of ketoconazole for guidance on how to administer abiraterone acetate.” slip op. at 17

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. Tr. 20:10–19. We determine that there is insufficient evidence that the alleged unpredictable and unexpected results of abiraterone acetate and prednisone are objective indicia of nonobviousness of the challenged claims. Patent Owner does not sufficiently tie the allegedly unpredictable and unexpected result to the administration of abiraterone acetate and prednisone as claimed.

    “Based on the information presented during trial, we understand that ketoconazole and abiraterone acetate do not have identical mechanisms. See, e.g., Ex. 2038 ¶¶ 25–39, Figs. 4, 5). As noted by both Petitioner and Patent Owner, however, abiraterone acetate and ketoconazole are both steroid synthesis inhibitors, particularly, CYP17 inhibitors. Pet. 26; PO Resp. 13– 15; Reply 2, 5, 9. Both parties appear to agree that, based on their respective mechanisms of action, administration of ketoconazole would inhibit production of cortisol, and administration of abiraterone acetate inhibits one of the pathways of cortisol production. Pet. 5, 26; Tr. 12:18–19; PO Resp. 14, Figs. 1, 2; Ex. 1003, 2318; Ex. 1023, 3, Fig. 1. Patent Owner takes the position that abiraterone acetate “allows some cortisol to be made.” Tr. 31:27–29. Although Patent Owner urges us to focus on the differences in the mechanisms of ketoconazole and abiraterone acetate, we look not only at the differences, but also at the similarities. The evidence demonstrates that one of ordinary skill would have been aware of the differences and the similarities in the mechanisms and, nevertheless, would have compared and analogized between the two. See, e.g., Ex. 1003, 2318, Figure 1; Reply 6 (citing Ex. 1104 ¶¶ 14–31; Ex. 1097 ¶¶ 44–49). Both O’Donnell and Barrie refer to ketoconazole in their discussions of abiraterone acetate, indicating that teachings regarding ketoconazole administration were a starting point for exploration of abiraterone acetate administration. Ex. 1003, 2318; Ex. 1005, Table 1. 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. 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. With this knowledge, and given the teachings of the prior art on administration of ketoconazole and administration of abiraterone acetate, we find that one of ordinary skill in the art would look to the administration of ketoconazole for guidance on how to administer abiraterone acetate.” slip op. at 18

    “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

    “Gibbs, however, explicitly teaches: The EGF receptor is also the target for the development of inhibitors of the intracellular tyrosine kinase domain. ZD-1839 and CP-358,774, competitive inhibitors of ATP binding to the receptor’s active site, are currently in clinical trials (12, 13). Their mechanism of action has led to some concern about safety, given the variety and physiological significance of protein kinases and other enzymes that bind ATP. However, these compounds appear to have good anti-cancer activity in preclinical models, with an acceptable therapeutic index, particularly in patients with non-small cell lung cancer. Ex. 1010, 10 (emphasis added). As erlotinib (i.e., CP-358,774) is one of only two compounds mentioned, and as Gibbs clearly states “these compounds,” the clear inference is that erlotinib has anti-cancer activity against non-small cell lung cancer. We credit the testimony of Dr. Giaccone, who testified that the statement in Gibbs “is a pretty strong and precise statement saying, there is activity in non-small cell lung cancer patients.” Ex. 2020, 115:12‒20. In addition, Dr. Giaccone testified further that statement by Dr. Gibbs would have been based on the information he had at the time, and that as Dr. Gibbs was a reputable pharmacologist, and as the statement was made in “a peer-reviewed journal of high impact,” he would have trusted that Dr. Gibbs “was saying something very important.” Ex. 2020, 115:12‒20. Moreover, Dr. Gibbs testified: Q Dr. Gibbs, let’s go back to Exhibit 1010. So you never attempted to offer any sort of correction for this publication. Isn’t that correct? A That is correct. Q And you state in your declaration that you have written over 128 articles. Isn’t that correct? A That is correct.

    “Patent Owner’s arguments are unavailing. That is, we find that the ordinary artisan would have combined Gibbs or OSI 10-K with Schnur and had a reasonable expectation of success of achieving the invention of challenged claims 44 and 53. In that regard, we agree with Petitioner (Pet. 26) that Schnur discloses all of the elements of claims 44 and 53, except for specifically teaching the treatment of non-small cell lung cancer. Specifically, Schnur teaches a genus of compounds that encompasses erlotinib (Ex. 1009, 1:9‒11) in which the synthesis of erlotinib is specifically disclosed (id. at 22:30‒49 (Example 20)), and erlotinib is specifically claimed (id. at 39:33 (claim 8)). In addition, Schnur discloses the treatment of hyperproliferative disorders such as cancer (id. at 1:9‒11), and specifically claims treating lung cancer with the genus of compounds (id. at 14:1‒13).

Patent Owner notes further that ZD-1839, which was also disclosed by Gibbs, successfully emerged from the clinic with FDA-approved indications for the treatment of non-small cell lung cancer.
