Opinion

PLEXXIKON INC., Case No. 4:17-cv-04405-HSG

Plaintiff, ORDER REGARDING MOTIONS TO vs. EXCLUDE DAMAGES EXPERTS’ OPINIONS Re: Dkt. Nos. 169, 202 CORPORATION, Defendant.

Pending before the Court are the parties’ motions to exclude certain expert opinions and testimony related to damages. Plaintiff Plexxikon Inc. (“Plexxikon”) moves to exclude opinions and testimony of defendant’s damages expert, James E. Malackowski. Dkt. No. 169 (“Pl. Mot.”). Defendant Novartis Pharmaceuticals Corporation’s (“Novartis”) moves to exclude the testimony of plaintiff’s damages expert, Gregory J. Leonard. Dkt. No. 202 (“Def. Mot.”). The Court heard oral argument on these motions on November 1, 2019. See Dkt. No. 341. As detailed below, the Court DENIES Novartis’ motion and GRANTS IN PART and DENIES IN PART Plexxikon’s motion. This is a patent infringement case related to Plexxikon’s patents for kinase inhibitors. Plexxikon accuses Novartis’ melanoma drug Tafinlar, which Novartis acquired for $2 billion from GlaxoSmithKline in 2015. Tafinlar works by inhibiting B-Raf, a type of kinase. The parties agree that the asserted patents have never been licensed. Nevertheless, both parties’ damages experts rely on purportedly comparable licenses under a “hypothetical negotiation” framework in order to determine a reasonable royalty for the asserted patents. both parties would have had “walk away points” beyond which they would not have entered a license. See Dkt. No. 403-6 (“Leonard Report”) ¶ 45. For Plexxikon, the walk-away point relates to the drug Zelboraf, which is sold by its licensee, Roche.1 Zelboraf is not covered by the asserted patents. See id. ¶ 78. However, Zelboraf competes directly with Tafinlar as the only other B-Raf inhibitor on the market. Id. ¶ 61. Dr. Leonard opines that Plexxikon would have considered the “opportunity cost” of licensing to Novartis in terms of lost royalties from Zelboraf sales. Id. ¶ 60. Assuming that Zelboraf would capture the projected Tafinlar sales in the absence of a Novartis license, Dr. Leonard concludes that Plexxikon would not have accepted less than a 5.5% royalty rate. Id. ¶ 71. Separately, Dr. Leonard opines that the Roche collaboration agreement that covers Zelboraf is also the most comparable license. Id. ¶ 83. Although they involve different patents, Plexxikon’s technical expert opines that the technology is comparable, and Dr. Leonard finds that the markets are similar because Zelboraf and Tafinlar serve the same patients through the same mechanism of action and Roche and Novartis are similarly situated. Id. ¶ 103. Since the Roche agreement also involves other types of collaboration (“know-how,” identification of a single lead compound, etc.), Dr. Leonard apportions the value of the intellectual property by comparing royalties in countries that did and did not have patent protection. Id. ¶¶ 107-09. Dr. Leonard thus concludes that without these additional factors, the effectively royalty rate for the patents would be 6.26%-12.52%. Id. ¶ 144. Novartis’ expert, Mr. Malackowski, disagrees that the Roche collaboration agreement is comparable because, among other reasons, it identifies a specific compound and provides broad collaboration benefits. Dkt. No. 393-17 (“Malackowski Report”) at 102-07. By contrast, in a hypothetical negotiation, Plexxikon would have provided only a bare license, leaving the difficult work of identifying and developing a specific compound to Novartis. Id. at 107; see also Leonard Report ¶ 128 (agreeing that only bare license would be provided). During deposition, Mr.

1 Specifically, Hoffman-La Roche Inc. and F. Hoffman-La Roche Ltd. (together, “Roche”). Dr. Malackowski testified that narrow patents that identify a specific compound are more valuable than broad genus patents because the latter are “like a state permit to dig for gold in California,” while the former provide “a treasure map with an X on the spot.” Dkt. No. 397-5 (“Malackowski Depo.”) at 37:20-38:3, 146:22-147:1. Instead of the Roche license, Mr. Malackowski opines that three other license agreements between Novartis and Rigel Pharmaceuticals, Inc., Curis, Inc., and Harvard Corporation (the “Rigel,” “Curis,” and “Harvard” licenses, respectively) are comparable. Malackowski Report at 50, 65. All three agreements are “freedom to operate” licenses. Id. at 41, 54, 62. The Rigel license arose from a legal settlement based on Novartis’ desire to avoid litigation. Id. at 40-41. It licensed patents related to a different kinase inhibitor for a drug used to treat a different cancer type. Id. at 46-49. The Curtis license also arose from a settlement of a lawsuit in which Novartis further argued that the patents were invalid. Id. at 50. Again, Novartis testified that it agreed to the license because doing so was cheaper than litigation. Id. at 53-54. The licensed drug treated skin cancer, not melanoma. Id. at 58. Last, the Harvard license arose when Harvard approached Novartis about licensing one of its products. Id. at 64. Novartis’ 30(b)(6) witness testified that “Novartis determined that it would be cheaper to take the license than risk litigation for freedom to operate purposes.” Dkt. No. 397-6 (“Waibel Depo.”) at 207:25-208:3. The licensed drug targets multiple myeloma, not cancer, using a different type of inhibitor. Malackowski Report at 68. Mr. Malackowski opines that these licenses are comparable because the parties, the license terms, the patents, and the licensed product are all comparable. Namely, Rigel and Curtis are both biotechnology companies that focus on drug discovery and collaboration, similar to Plexxikon; the agreements provided a bare, non-exclusive license; the patents claim a broad genus of molecules without identifying a specific compound; the licensed products have similar value and were on the market for comparable amounts of time; and the parties were in a similar financial state at the time of the license. Id. at 42-50, 54-62, 64-71. Based considerably on these licenses, Mr. Malackowski concludes that a reasonable royalty would be a lump sum of $3.5 million. Id. at 96. However, he also provides an alternative reasonable royalty opinion based on a greater discounting of the Federal Rule of Evidence 702 allows a qualified expert to testify “in the form of an opinion or otherwise” where:
