Additional experience could substitute for the advanced degree. To the extent necessary, one of skill in the art may collaborate with one or more other persons of skill in the art for one or more aspects with which the other person may have expertise, experience and/or knowledge that was obtained through his or her education, industrial or academic experiences.

“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

“We find that the prior art does not discourage or teach away from administration of prednisone to mCRPC patients. The teachings of the references do not rise to the level of teaching away from Petitioner’s proposed combination—they do not criticize, discredit, or otherwise discourage the solution claimed, but rather, as Petitioner argues, encourage exploration of such a combination. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004) (explaining “[t]he prior art’s mere disclosure of more than one alternative does not constitute a teaching away from any of these alternatives because such disclosure does not criticize, discredit, or otherwise discourage the solution claimed”). Although glucocorticoids have certain risks, we are not persuaded that those risks outweigh the positive effects in seriously ill patients with limited life expectancy, such that a person of ordinary skill in the art would have been dissuaded from administering glucocorticoids to a mCRPC patient. We have sufficient evidence before us that the risks of glucocorticoid therapy were known, that the longevity of mCRPC patients was short, that glucocorticoid therapy was reasonably well tolerated in the short term, and that any long-term side effects would have been viewed by one of ordinary skill in the art in light of the same. Thus, we are persuaded that one of ordinary skill in the art would not have been dissuaded from administering abiraterone acetate with prednisone, but rather, would have been motivated to co-administer prednisone with abiraterone acetate.” slip op. at 23

“The facts of the case at hand provide a stark contrast. As we have found above, while the prior art recognized rapamycin as a promising immunosuppressant, it was only one among many possible lead compounds. Furthermore, the prior art shows that chemists were pursuing a number of avenues to increase solubility, including making derivatives but also other approaches such as formulation techniques or prodrugs. And most tellingly, in contrast to Bristol-Myers Squibb where the experts agreed on the type and location of the potential substituents, here the experts diverge significantly. As discussed above, we credit the testimony of Novartis’ experts over Par’s, and find that the options of substituent and substituent position would not have been as narrow as those proposed by Par. In sum, we find that the person of ordinary skill in the art at the time the invention was made would have been faced with a large number of decision points along the lead compound analysis proposed by Par. The number of potential compounds encompassed by this decision tree is unclear, but would be far larger than the three compounds Dr. Jorgensen discusses. Only by making the “right” choice at each step would the skilled artisan arrive at everolimus, the compound of claim 10 and the basis of Par’s obviousness challenge. In light of these facts, we cannot conclude that the options faced would have been—in the words of the Federal Circuit—finite, small, or easily traversed. We, therefore, cannot conclude that the compound of claim 10, and by extension, the compounds of claims 1–3, would have been obvious to one of skill in the art as of October 1992.” slip op. at 35

“Based on our review of the entirety of the record, we cannot conclude, as Par contends, that the C40 hydroxyl group would be the obvious, optimal, or preferred location for substitutions to rapamycin. Dr. Jorgensen’s testimony to that effect is premised on his assertion that a person of ordinary skill in the art would have first narrowed the group of possible substitution positions to the C10, C28, or C40, because those are the hydroxyl groups of rapamycin. Ex. 1003 ¶ 142 (“person of ordinary skill in the art would have focused on hydroxyl groups on rapamycin as initial targets for modification.”). This statement, however, is based only on Dr. Jorgensen’s statement that the reactions of hydroxyl groups are “among the most fundamental and elementary reactions taught in beginning organic chemistry courses.” Id. Dr. Jorgensen provides no objective, documentary evidence that would indicate that starting with hydroxyl groups was an accepted rule followed by medicinal chemists in the field. To the contrary, Dr. Roush testifies that Dr. Jorgensen’s focus on rapamycin’s hydroxyl groups is inconsistent with the prior art as a whole, and provides multiple citations to the documentary evidence in the record supporting his testimony. Ex. 2093 ¶¶ 197, 206–216 (citing prior art modifications at the C9, C26, C27, C28, and C32 positions). For example, Ondeyka14 discloses demethylation of the methoxy group at rapamycin’s C29 position, while Caulfield15 discloses oxime substitutions at C32.16 We have weighed the testimony of Drs. Jorgensen and Roush on this point, and find Dr. Roush’s to be the more credible. While we agree with Par that a person of ordinary skill in the art would have considered rapamycin’s C40 position as a candidate for substitution, that site must be evaluated as one potential substitution site among many that were being modified in the field at the time of the invention.” slip op. at 24

We, therefore, cannot conclude that the compound of claim 10, and by extension, the compounds of claims 1–3, would have been obvious to one of skill in the art as of October 1992. With respect to the second ground of unpatentability, pertaining to the method of treatment claims 8 and 9, Par’s obviousness arguments are premised on the conclusion that everolimus would have been obvious. See Pet. 48–51 (“claims 8 and 9 would have been obvious to a person of ordinary skill in the art in view of the art that makes the 40-O-2- hydroxyethyl-rapamycin derivative obvious”). As we conclude that everolimus has not been shown to be obvious, we reach the same conclusion as to the methods of claims 8 and 9. The addition of Hughes to the ground of unpatentability does not provide any of the teachings we found lacking from the art asserted in the first ground of unpatentability.

“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. Q And so you have -- you would agree with me that you have experience in writing articles such as this Gibbs reference. Isn’t that correct? A That is correct. Q And of the 128 articles, have you ever asked that an article be retracted? A I have not. Q And according to your C.V., one of your areas of expertise is that you have extensive journal editorial experience. Isn’t that correct? A Yes. Ex. 1049, 29:18‒30:16 (objections omitted).

“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). Thus, as Schnur specifically discloses and claims erlotinib, and specifically discloses and claims treatment of lung cancer, we conclude that Schnur suggests the treatment of lung cancer with erlotinib. As acknowledged by Petitioner, however, Schnur does not specifically teach treatment of non-small cell lung cancer. Pet. 26.” slip op. at 25

“We find Patent Owner’s evidence of non-obviousness to be weak as to long-felt need. All types of objective evidence of nonobviousness must be shown to have a nexus to the claimed invention. In re GPAC Inc., 57 F.3d 1573, 1580 (Fed. Cir. 1995) (nexus generally); In re Huang, 100 F.3d 135, 140 (Fed. Cir. 1996) (commercial success); Rambus Inc. v. Rea, 731 F.3d 1248, 1256 (Fed.

As we have discussed above, the claims are not limited to the treatment of human patients with non-small cell lung cancer, but are drawn to treatment of mammals. In addition, the claims do not require a clinically significant effect. See, e.g. Tr. 50:16‒17 (Counsel for Patent Owner stated that the claims do not require a “major clinical response, which is a higher standard than treatment as defined in the claims.”). As Patent Owner notes, 1,631 new drugs were tested in Phase II clinical trials for non-small cell lung cancer (PO Resp. 59 (citing Ex. 2008, 1)), and, thus, those compounds made it through preclinical trials. 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.

“UCN-01 alone, and in combination with the DNA damaging agent mitomycin C. See Dec. 27–28; Ex. 1004. Noting that the two compounds had 1) complementary effects in delaying cell cycle progression; and 2) synergistic cytotoxic and antitumor effects, Akinaga expressly suggests the combination of UCN-01 and DNA-damaging agents for cancer chemotherapy. Id. Seynaeve establishes that UCN-01 inhibits multiple tyrosine kinases in human breast cancer cells coincident with promoting cell cycle arrest. Dec. 28–29, 34–35; Ex. 1014. Accordingly, “Seynaeve proposes a link between UCN-01’s inhibitory effects on tyrosine kinases and its inhibitory effects on the cell cycle.” Dec. 29.8 Akinaga further suggests combining a chemotherapeutic DNA damaging agent with UCN-01 because the two compounds cause delays in different stages of the cell cycle and result in synergistic cytotoxic and antitumor effects, whereas Seynaeve examines the effects of UCN-01 on the cell cycle of human carcinoma cells and shows that UCN-01 is a tyrosine kinase inhibitor.

Because both references 8 Considering Seynaeve teachings with respect to UCN-01, we reject Patent Owner’s contention that “there is no evidence from which one can reasonably find that Petitioner carried its burden of proving that people of ordinary skill in the art considered either staurosporine or UCN-01 to be tyrosine kinase inhibitors.” See Reh’g.

“Akinaga teaches that UCN-01 inhibits v-src (as does Seynaeve), one of ordinary skill in the art would have no reason to believe that UCN-01 would inhibit its cellular homolog c-src because v-src is “found only in chickens” and “is more difficult to inhibit.” Dec. 28, 32. We instead credited the testimony of Petitioner’s expert, Dr. Eastman that “[b]ecause v-Src and c-Src have similar structures, compounds that inhibit the tyrosine kinase activity of v-Src generally inhibit c-Src as well.

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 unpersuaded by Patent Owner’s arguments. Claim 1 is drawn to a dosage form—a composition. Patent Owner does not point out how the recitation of “abuse deterrent” in the preamble modifies the structurally complete dosage form recited in the body of claim 1. See Catalina Mktg. Int'l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (“[A] preamble is not limiting ‘where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.’”) (quoting Rowe v. Dror, 112 F.3d 473, 478 (Fed.Cir.1997)). We conclude, therefore, that the term “abuse deterrent” is a goal of the invention, that is, it is merely a statement of intended use that is not entitled to patentable weight.” slip op. at 13

“exclude all of Dr. Sun’s experiments. Paper 32. In the Motion, Petitioner urged us to exclude Dr. Sun’s experiments 1–4 from the record “because they are irrelevant to any ground upon which trial was instituted and include[] information whose probative value (if any) is substantially outweighed by a danger of confusing the issues.” Id. at 2 (emphasis added) (citing Paper 23 ¶ 6). Petitioner continued: “the compounds HCFC-123 and HFC-236ea that were used in Experiments 1–4 are not relevant to the issues in this trial. These compounds were not used in [Miller’s example 1].” Id. (citing Ex. 1066 ¶¶ 65–68). In reply to the Motion to Exclude, Petitioner further argued that Dr. Sun’s experiments 1–4 demonstrate that “HCFC-123 and HFC-236ea behave completely differently from HFC-245cb.” Paper 37, 2 (emphasis added). Petitioner made those same arguments in the Reply to Patent Owner’s Response. Reply 12–14. As we explained in the Final Decision (Final Dec. 21–22), and reiterate here, Petitioner’s reliance on Dr. Sun’s experiments 1–4, and the results thereof, is inconsistent with Petitioner’s arguments that Dr. Sun’s experiments 1–4 are irrelevant, prejudicial, and should be excluded from the record. Petitioner’s arguments to the contrary in the Request for Rehearing express mere disagreement with our determination in the Final Decision and weighing of the evidence.

“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. We consider this experience more relevant than certificates or training. Thus, we determine that Dr. Vaux is qualified to provide opinions about the motivations, understandings, and actions of one of ordinary skill in the art.” slip op. at 15

We agree with the qualifications on which the parties agree and find that one of ordinary skill in the art would have an M.D. or equivalent degree, with a residency and specialized training in the diagnosis or treatment of inherited metabolic disorders, such as UCDs and other nitrogen retention disorders.

“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. The ’859 publication teaches that maintaining normal plasma ammonia levels was desirable in the art. Although specific measurements of 8 Patent Owner notes that the parties do not dispute the meaning of any of the claim terms. PO Resp. 2. Because the meaning of the terms in the challenged claims are evident from their ordinary meaning and not controversial, we need not provide a separate analysis of them. See Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (“claim terms need only be construed ‘to the extent necessary to resolve the controversy.’ Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999).”). plasma ammonia do not necessarily indicate the upper limit of normal consistently across different ways of measuring it, the ’859 publication teaches that treatment would have been considered to be effective when plasma ammonia levels were less than what is determined to be the upper limit of normal in a given case. 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.

“Specification suggest that the inventors contemplated the induction of a differentiation pathway. See Ex. 2011 ¶ 4. To the contrary, and as discussed above in Section 1(C), the Specification focuses on the use of DNA damaging agents in combination with tyrosine kinase inhibitors to force damaged cells to override the G2 arrest checkpoint and enter mitosis before completing DNA repairs. See, e.g., Ex. 1001, 3:46–48 (“By preventing delays in G2, cells will enter mitosis before the DNA is repaired and therefore the daughter cells will likely die.”). Accordingly, we agree with Patent Owner that, in light of the Specification, one of ordinary skill in the art would not understand the terms “enhanc[ing] cell death” and “enhancing apoptosis” to encompass the a process by which cancer cells are differentiated, become mortal, and, subsequently, “live out their days and die.” See Pet. 29; Ex. 1002, ¶ 127.” slip op. at 14
