`I, Robert D. Stoner, Ph.D., declare as follows:
`
`I.
`
`Introduction
`A. Background and Qualifications
`1.
`I am over the age of eighteen and otherwise competent to make this
`
`declaration. I have personal knowledge of the facts set forth in this Declaration and
`
`am competent to testify to the same.
`
`2.
`
`I am a Principal at Economists Incorporated, and an expert in
`
`industrial organization, with more than twenty five years of experience in
`
`consulting, antitrust, and economic research. I provide expert witness testimony
`
`and consulting in a variety of areas, including reasonable royalties, commercial
`
`success, damages estimation, and business strategy.
`
`3. My expertise and experience encompass a variety of topics, including
`
`intellectual property, competition, antitrust, utility regulation, international trade,
`
`commercial litigation, and class action. My work in intellectual property spans the
`
`life sciences (with specific industry expertise in pharmaceuticals, medical devices
`
`and drug wholesaling) as well as electronics (including computer memory, digital
`
`music, smart phones, text messaging and telecommunications). I have worked on
`
`projects in a diverse range of other industries (such as pharmaceutical data, electric
`
`utilities, grocery stores, casinos, hospital beds, automobiles and oil refining and
`
`marketing). I frequently provide expertise and analysis in evaluating commercial

`success in the pharmaceutical industry.
`
`4.
`
`I earned my Ph.D. and M.A. in Economics from Berkeley, University
`
`of California in 1978 and 1976, respectively, and my B.A. in Economics from
`
`Santa Cruz, University of California in 1970. At Santa Cruz, I received both
`
`General Honors and Honors in Economics. I have also published research in
`
`several peer-reviewed academic journals.
`
`5.
`
`I am educated and experienced in economics, as detailed in this
`
`Declaration. My qualifications and credentials are also fully set forth in my
`
`curriculum vitae, provided as WCK1078. I understand that my declaration will be
`
`included in Petitioner's Exhibit List as WCK1077. I have examined and am
`
`familiar with the contents of WCK1048-1080. Each of these Exhibits is publicly
`
`available, or derived from documents that are publicly available, and is a true and
`
`correct copy of the documents cited, including but not limited to the following:

`not dependent on the substance of my testimony or the outcome of this matter.
`
`7.
`
`For this declaration, I was asked to evaluate aspects of commercial
`
`success, from an economic perspective, as it pertains to Zytiga® (abiraterone
`
`acetate) and U.S. Patent No. 8,822,438 (the “’438 Patent” or the “Patent-at-
`
`Issue”).1 (WCK1001.)
`
`8.
`
`I understand that Alan H. Auerbach and Arie S. Belldegrum are the
`
`named inventors and that, according to the United States Patent and Trademark
`
`Office (“USPTO”) records, the ’438 Patent is currently assigned to JANSSEN
`
`ONCOLOGY, INC. (“Janssen” or “Patent Owner”). (WCK1001.)
`
`9.
`
`This declaration is a statement of my opinions in this matter and the
`
`basis and reasons for those opinions. In forming the opinions expressed in this
`
`declaration, I have relied upon my education, experience, and knowledge of the
`
`
`1 I understand that the Patent Trial and Appeal Board instituted trial in Amerigen
`
`Pharms. Ltd. v. Janssen Oncology, Inc., IPR2016-00286 on May 31, 2016. I also
`
`understand that in conjunction with the petition, Amerigen filed the declaration of
`
`DeForest McDuff dated December 4, 2015 (the “McDuff Declaration”). I reviewed
`
`the McDuff Declaration. I also reviewed the declaration of Ivan T. Hofmann, filed
`
`in conjunction with Mylan Pharmaceuticals Inc.'s petition for inter partes review
`
`(IPR2016-01332).

`Declaration of Robert D. Stoner, Ph.D. (Exhibit 1077)
`concerning objective indicia of non-obviousness.2 Specifically, I have been asked
`
`to evaluate the “commercial success” of Zytiga®, including an inquiry as to
`
`whether any substantial level of sales can be attributed to the formulations and
`
`methods claimed in the ’438 Patent, as opposed to other drivers such as feature of
`
`the claims that already existed in the prior art, other patent or market exclusivities,
`
`or other commercial drivers such as marketing and promotion.3
`
`
`2 I understand that objective indicia of non-obviousness are sometimes called
`
`secondary considerations of non-obviousness, and hence these terms will be used
`
`interchangeably in my report.
`
`3 It is my understanding that “commercial success” is a legal term of art that is used
`
`as a secondary indicia of non-obviousness of patent(s) being contested. I further
`
`understand that in order for “commercial success” to indicate non-obviousness of
`
`the contested patent(s), it must be shown both that: (a) the product allegedly
`
`embodying the patent(s) achieved financial success; and (b) there is a nexus
`
`between that success and the patent(s) in suit. Such a nexus would not exist if, for
`
`example, the financial success of the product were due to: (i) elements of the prior
`
`art that would have predicted the success; (ii) blocking patents or other external
`
`factors that would interfere with the economic incentive of a third party to develop
`
`the patented invention; and/or (iii) evidence that the financial success was a

`Declaration of Robert D. Stoner, Ph.D. (Exhibit 1077)
`12. Based on the information available to me and my analysis to date, I
`
`have reached the following conclusions:
`
` First, even assuming that Janssen can establish that Zytiga®’s sales
`
`were considered substantial or “commercially successful” for
`
`purposes of objective indicia, Janssen cannot show there is a nexus
`
`between commercial sales of Zytiga® and the claims at issue of the
`
`’438 Patent. Rather, the record evidence demonstrates that other
`
`dynamics extrinsic to the ’438 Patent are responsible for those sales.
`
` Such extrinsic factors include the existence of the ’213 patent, which
`
`serves as a classic “blocking patent” in this case, which allowed
`
`Janssen to exclude others from the market and served to limit the
`
`economic incentives of third parties to develop a competing regimen
`
`to that claimed in the ’438 Patent at issue here. Likewise, I understand
`
`that upon its approval on April 28, 2011, Zytiga® was awarded a 5-
`
`year period of statutory exclusivity where no third party could even
`
`apply for FDA-approval for a competing product. That exclusivity,
`
`coupled with the ’213 patent, in my opinion created a significant
`
`function of marketing/promotion of the product rather than intrinsic qualities that
`
`were the embodiment of the patent.
`

`
`WCK1077
`
`
`
`Inter Partes Review of U.S. Patent No. 8,822,438
`Declaration of Robert D. Stoner, Ph.D. (Exhibit 1077)
`obstacle to competition, both of which have nothing to do with the
`
`’438 patent, that are responsible for Zytiga®’s sales and market
`
`position.
`
` Second, to the extent that the ’438 Patent has any relevance to
`
`Zytiga®’s commercial sales, it is my understanding that the features
`
`of the claims that contribute to sales, if any, already existed in the
`
`prior art, are not novel or nonobvious, and therefore are not relevant to
`
`the question of commercial success as an objective indicia of non-
`
`obviousness. I understand that both abiraterone and prednisone were
`
`previously known to have anti-cancer effects, and their combination
`
`had predictable (non-synergistic) effects that drove the sales of
`
`Zytiga®. Thus, even assuming Zytiga® had substantial sales,
`
`revenues, market share, profits, and return on investment, Janssen
`
`cannot demonstrate that the commercial sales of Zytiga® are a direct
`
`result of any arguably novel features of the ’438 Patent claims at
`
`issue.
`
` Third, while Zytiga has enjoyed substantial sales, the evidence I have
`
`seen indicates that competition from Xtandi® (enzalutamide) has
`
`resulted in Zytiga® losing share of both pre- and post-chemo
`
`metastatic castrate-resistant prostate cancer (“mCRPC”) sales.
`
`10
`
`WCK1077
`
`
`
`Inter Partes Review of U.S. Patent No. 8,822,438
`Declaration of Robert D. Stoner, Ph.D. (Exhibit 1077)
`Zytiga® is priced below Xtandi®, with the likelihood that Xtandi®
`
`will become the premier treatment option. It is also my understanding
`
`that Zytiga®’s share of the larger pre-chemo mCRPC patient
`
`population (where it was approved later) is significantly smaller than
`
`in the post-chemo population. Based on the record that I have seen,
`
`this reflects a drawback that Zytiga® must be used in combination
`
`with prednisone, while more recent pre-chemo mCRPC drugs, such as
`
`Xtandi®, while equally or more efficacious, can be used alone, i.e., as
`
`a monotherapy. As such, not only does the combination of Zytiga®
`
`with prednisone not have synergistic effects, but the combination also
`
`has weaknesses relative to more recent mCRPC drugs.
`
` Third, any “unexpected” commercial success, if it occurred at all, is
`
`not relevant for an evaluation of commercial success as an indicia of
`
`nonobviousness.
`
` And fourth, Janssen has not made a showing in this matter that
`
`Zytiga®’s sales, though appearing significant on the surface,
`
`constitute a commercial success in the economic sense of high
`
`profitability and rate of return above benchmark J&J levels. I am not
`
`aware of any complete data produced by Janssen on profits or return
`
`on investment for Zytiga®, both of which are relevant to an economic

`
`III. Background
`A.
`Prostate cancer
`13. Prostate cancer occurs in the male prostate, a small “gland that
`
`produces the seminal fluid that nourishes and transports sperm.” (WCK1048.)
`
`“Prostate cancer is one of the most common types of cancer in men,”(WCK1048)
`
`with a one-in-seven lifetime risk of being diagnosed.(WCK1049.) In recent years,
`
`estimates for prostate cancer suggest over 220,000 new cases and more than
`
`27,000 deaths annually in the US alone.(Id.)
`
`14. Patients diagnosed with prostate cancer may undergo a variety of
`
`treatments options, including: (1) active surveillance (i.e., no action taken until
`
`disease progresses) (WCK1048); (2) radiation therapy (i.e., using high-powered
`
`energy to kill cancer cells) and surgical removal of the prostate (id.); (3)
`
`chemotherapy (i.e., using drugs to kill cancer cells) (id.); (4) hormone therapy (e.g.,
`
`interrupting production of testosterone to kill or slow growth of cancer cells) (id.);
`
`and (5) other treatments such as cryosurgery (e.g., freezing tissue to kill cancer
`
`cells) and immunotherapy (e.g., genetically engineering immune cells to kill cancer
`
`cells) (id.).
`
`15. Castrate-resistant prostate cancer (“CRPC”) refers to prostate cancer
`
`that is able to grow despite usage of treatments lowering androgen
`
`12
`
`WCK1077

`
`
`Inter Partes Review of U.S. Patent No. 8,822,438
`Declaration of Robert D. Stoner, Ph.D. (Exhibit 1077)
`production.(WCK1050.) Metastatic castrate-resistant prostate cancer (“mCRPC”)
`
`refers to CRPC that has metastasized beyond the prostate into other parts of the
`
`body.(Id.) Studies have found that approximately 10% to 20% of patients with
`
`prostate cancer develop CRPC within 5 years of follow-up.(WCK1051, 1180.)
`
`Among these patients, at the time of CRPC diagnosis, at least 84% would already
`
`have mCRPC, and of the remaining non-metastatic patients at the time of
`
`diagnosis, 33% would develop mCRPC within two years. (Id.)
`
`B.
`Zytiga® (abiraterone acetate)
`16. Zytiga® (abiraterone acetate) is a CYP17 inhibitor indicated in
`
`combination with prednisone for the treatment of mCRPC.(WCK1052, 1;
`
`WCK1053.) Zytiga® works by interrupting androgen production (including, for
`
`example, testosterone) in the testes, adrenal glands, and tumor. (WCK1053.)
`
`Zytiga® is a type of hormone therapy (WCK1048), usually when prostate cancer
`
`persists or recurs despite previous hormone therapy. (WCK1054.)
`
`17. Zytiga®’s label indicates a recommended dose of “1,000 mg ([via]
`
`four 250 mg tablets) administered orally once daily in combination with
`
`prednisone 5 mg administered orally twice daily.” (WCK1052, 1.) The FDA
`
`initially approved Zytiga® in April 2011 with a label indication of use limited to
`
`patients whose prostate cancer progressed after treatment with docetaxel, a
`
`chemotherapy drug. (WCK1055; WCK1056.) In December 2012, the FDA

`WCK1077
`
`
`
`Inter Partes Review of U.S. Patent No. 8,822,438
`Declaration of Robert D. Stoner, Ph.D. (Exhibit 1077)
`approved Zytiga® for treatment of patients with or without prior chemotherapy
`
`treatment. (WCK1052, 1; WCK1056.) And in March 2015, Zytiga®’s label was
`
`enhanced to reflect that “Zytiga plus prednisone provides a statistically significant
`
`[overall survival] benefit vs. prednisone alone.” (WCK1057, 1-2.) Nonetheless, it
`
`is my understanding that “the label enhancement does not appear to be having a
`
`meaningful impact in driving Zytiga share or demand volume.” (Id., 2.)
`
`C. The ’438 Patent
`18. U.S. Patent No. 8,822,438 (“the ’438 Patent”), entitled “Methods and
`
`Compositions for Treating Cancer,” was filed on February 24, 2011 and issued on
`
`September 2, 2014. (WCK1001.) I understand a provisional application was filed
`
`on August 25, 2006.
`
`19. The ’438 patent abstract reads as follows (id.):
`
`Methods and compositions for treating cancer are described herein.
`More particularly,
`the methods for
`treating cancer comprise
`administering a 17α-hydroxyalse/C17,20-lyase
`inhibitor, such as
`abiraterone acetate
`(i.e., 3β-acetoxy-17-(3-pyridyl)androsa-5,16-
`diene), in combination with at least one additional therapeutic agent
`such as an anti-cancer agent or a steroid. Furthermore, disclosed are
`compositions comprising a 17α-hydroxyalse/C17,20-layse inhibitor, and
`at least one additional therapeutic agent, such as an anti-cancer agent
`or a steroid.
`20.
`Independent claim 1, the only independent claim, reads as follows: “A
`
`method for the treatment of prostate cancer in a human comprising administering

`to said human a therapeutically effective amount of abiraterone acetate or a
`
`pharmaceutically acceptable salt thereof and a therapeutically effective amount of
`
`prednisone.” (Id.)
`
`D.
`21.
`
`Prosecution of the ’438 Patent
`
`I understand that the ’438 Patent was filed in February 2011 (with a
`
`prior provisional filing in August 2006) and issued in September 2014. (Id.) During
`
`the period between filing and issuance, I understand that Johnson & Johnson
`
`(“J&J”) and related parties corresponded with the USPTO regarding the
`
`patentability of the presented claims.4
`
`22.
`
`In particular, I understand that the USPTO rejected the presented
`
`claims several times due to obviousness and double patenting, and at least twice
`
`for lack of evidence of commercial success, but ultimately allowed 20 claims based
`
`on “unexpected commercial success of the launch of the drug” and withdrawal of a
`
`co-pending patent application. (WCK1031, 206.) See Attachment B-1 for an
`
`overview of the prosecution timeline.
`
`E.
`The ’213 “blocking” Patent
`23. U.S. Patent No. 5,604,213 (“the ’213 Patent”), entitled “17-
`
`
`4 For brevity, I refer to these entities collectively as Johnson & Johnson or J&J
`
`throughout, as appropriate.

`WCK1077

`Substituted Steroids Useful in Cancer Treatment,” describes the abiraterone
`
`compound and methods for treating an androgen-dependent or estrogen-dependent
`
`disorder (such as prostate cancer) using that compound. (WCK1030.) According to
`
`the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations
`
`(i.e., “Orange Book,” an electronic database listing all approved prescription drugs
`
`along with a listing of patents relevant to those drugs, the ’213 Patent is listed in
`
`connection with Zytiga®. (WCK1058.) The ’213 Patent was filed in 1994 and
`
`issued in 1997. (WCK1001.) According to the FDA, the ’213 Patent is expected to
`
`expire in December 2016. (WCK1058.)
`
`IV. Analysis of Commercial Success
`A. Economic relevance and the definitions of commercial success and
`nexus relative to objective indicia of nonobviousness
`
`24.
`
`I understand that an obviousness analysis involves comparing a patent
`
`claim to the prior art to determine whether the claimed invention would have been
`
`obvious to a person of ordinary skill in the art in view of the prior art, and in light
`
`of the general knowledge in the art. I also understand that, if it is determined that a
`
`person of ordinary skill in the art would have reached the claimed invention
`
`through routine experimentation, the invention may be deemed obvious. I also
`
`understand that obviousness can be established by a person of ordinary skill in the
`
`art combining or modifying the teachings of the prior art to achieve the claimed
`
`invention.
`
`16
`
`WCK1077
`
`
`
`Inter Partes Review of U.S. Patent No. 8,822,438
`Declaration of Robert D. Stoner, Ph.D. (Exhibit 1077)
`I further understand that, when determining the obviousness of an
`
`25.
`
`invention, one should also consider whether there are any objective indicia that
`
`support the non-obviousness of the invention.
`
`26.
`
`I understand that one of the objective indicia that may be considered
`
`when determining the obviousness of an invention is the commercial success of a
`
`product allegedly embodying the patented claims. It is also my understanding that
`
`“commercial success” is a legal construct that has been established through case
`
`law. Analysis of commercial success is premised on the concept that if a product is
`
`economically successful and that success has a legal nexus to the patent claims in
`
`question, it may provide objective evidence of nonobviousness.
`
`27.
`
`I understand that commercial success is relevant to the determination
`
`of a patent’s obviousness since the law presumes that an idea would have been
`
`brought to market sooner (by third parties) in response to market forces had it been
`
`obvious to persons skilled in the art. I further understand that evidence of
`
`commercial success is only relevant if there is a link or “nexus” between the
`
`alleged commercial success and the patentable features of the asserted claims. In
`
`other words, the patent owner must show that the commercial success is
`
`attributable to the alleged novel parts of a patent claim, and not on extrinsic factors
`
`(e.g., regulatory/other patent exclusivities or strong marketing/advertising efforts)
`
`that are unrelated or were already known in the prior art. I also understand that if
`
`17
`
`WCK1077
`
`
`
`Inter Partes Review of U.S. Patent No. 8,822,438
`Declaration of Robert D. Stoner, Ph.D. (Exhibit 1077)
`purported commercial success is due to an element in the prior art, no nexus exists.
`
`In essence, I understand that if the feature that drives the purported commercial
`
`success was known in the prior art, or wasn’t novel to the patent claims, such
`
`success is not pertinent. I also understand that if economic success arises from an
`
`unpatented feature of the product, the success is not relevant for the purposes of a
`
`“commercial success” analysis.
`
`28. Finally, I understand that an applicant asserting commercial success to
`
`overcome an obviousness rejection must come forward with evidence to establish
`
`both that the product was economically successful as well that there is a nexus
`
`between the claimed invention and any purported economic success.
`
`29. From an economic perspective, a “commercial success” analysis
`
`presumes that if an idea were obvious to market participants, then others would
`
`have brought that idea to market sooner had there been material economic
`
`incentives (i.e., the likelihood of economic profits) to do so. A finding of
`
`“commercial success,” in some circumstances, supports the notion that a patent
`
`was not obvious to those skilled in the art. Accordingly, analysis of “commercial
`
`success” frequently includes evaluation of sales, market shares, prices, profits,
`
`return on investment, and other metrics to draw inferences on economic incentives
`
`for development. Importantly, since analysis of commercial success provides
`
`potential indirect inferences relating to obviousness, its informative value depends
`
`18

`WCK1077
`
`
`
`Inter Partes Review of U.S. Patent No. 8,822,438
`Declaration of Robert D. Stoner, Ph.D. (Exhibit 1077)
`on the case-specific circumstances and whether those circumstances provided
`
`material economic incentives for development at the time of the alleged invention.
`
`30.
`
`I also understand that courts have found that commercial success may
`
`not provide objective indicia of nonobviousness for asserted claims of patents
`
`where the underlying product (or in the case of pharmaceuticals, the underlying
`
`compound) is protected by a patent and/or regulatory exclusivity that prevents
`
`competition in the market. That is because the existence of blocking patents
`
`disincentivizes third parties from pursuing a solution to a market demand if the
`
`solution would infringe a blocking patent. In this respect, I understand that a
`
`blocking patent is one that effectively blocks others from making, selling, or using
`
`a product without use of that patent.5 Finally, I understand that if
