Recognized by her clients as a “terrific oral advocate,” “superb in court” and “an incredible asset overall,”* Pamela J. Yates is a highly successful life sciences and product liability trial lawyer who is consistently named one of California’s “Top Women Litigators” and internationally recognized as a “Life Science Star.” Validating these client comments, in recent years, Ms. Yates has achieved several victories, including, most recently summary judgment on behalf of Bayer in a low dose aspirin case (July 2016), and in February 2016, a unanimous defense verdict on behalf of client Philip Morris USA. This follows Ms. Yates’ numerous trial successes in several Engle progeny cases in Florida state and federal courts, and two major Daubert victories excluding plaintiffs’ general causation experts in complex MDL proceedings on behalf of client Pfizer (In Re: Zoloft (Sertraline Hydrochloride) Products Liability Litigation, April 2014 and September 2015).

In addition to trying cases in multiple state and federal court venues, Ms. Yates also has extensive experience in MDL and class action work, and for many years has acted as national coordinating counsel in various mass tort cases. In that role, she has been responsible for all aspects of litigation, including trial, trial preparation and strategy, science and overall Daubert strategy.

Successfully defending pharmaceutical companies began early in her career when, as a young associate, Ms. Yates drafted the summary judgment in Daubert, which led to the US Supreme Court’s decision that ultimately set the standard for challenging the admissibility of expert testimony. Building on her success in Daubert, Ms. Yates’s career has involved significant expert and science related work. For example, Ms. Yates currently leads Bayer’s Xarelto science team, and has successfully led Pfizer’s expert science teams defending claims relating to Xarelto, Zoloft, and before that, hormone therapy (HT) products. Earlier in her career, her science and trial work involved Rezulin and silicone implants. In addition to her science related work on HT products, Ms. Yates served as co-lead trial defense counsel in several of the HT matters, securing back-to-back defense verdicts in West Virginia and Connecticut.

Ms. Yates’s stellar work has garnered significant recognition from a number of industry guides. Most Recently, Ms. Yates was selected by her peers and clients for inclusion in Benchmark Top 250 Women in Litigation. She is ranked in Chambers USA 2015 and 2016 for Nationwide: Product Liability & Mass Torts, with clients praising her as “‘an excellent science lawyer who makes highly technical concepts clear to a lay jury.” She was recognized as a Law360 Product Liability MVP, ranked in The Best Lawyers in America 2016 and 2017 for Biotechnology Law and Product Liability Litigation, and was previously named in the Litigation and Product Liability Lawyers (2014) Expert Guide by Legal Media Group. Ms. Yates’s victory as lead counsel for the science defense in Zoloft litigation for Pfizer Inc. was short-listed for Product Liability Impact Case of the Year at the 2014 LMG Life Sciences Awards and helped secure Ms. Yates’s LMG Products Liability Lawyer of the Year Award. She is also a member of the team that won Product Liability Practice of the Year for 2013 from Law360, and has been recognized as one of California’s top women litigators in the Daily Journal’s supplement feature, “Top Women Litigators” (2009-2013, 2015, 2016). Ms. Yates was named a “Life Science Star” in the 2013 – 2016 editions of Euromoney’s LMG Life Sciences and has been featured in Who’s Who Legal in the areas of Product Liability Defense (2007-2009, 2012, 2013 and 2016) and in Life Sciences (2010, 2012, 2013 and 2016). She is also recognized by Legal 500 US (2011-2016) for her work in Dispute Resolution: Product Liability, Mass Tort and Class Action – Pharmaceuticals and Medical Devices – Defense. In January 2006, Kaye Scholer’s product liability lawyers were awarded The American Lawyer Litigation Product Liability Department of the Year. The award specifically references several successes in the Rezulin litigation, which involved Ms. Yates. In August 2005, The National Law Journal’s “The Defense Hot List, sizing up Defense Firms With Big Wins” featured Ms. Yates’s defense verdict, discussed below, in a multiple plaintiff products case, In Re Rezulin Litigation.

Representative Matters

  • In January 2015, Ms. Yates was retained by Bayer Corporation as national counsel defending their oral anticoagulant prescription medicine, Xarelto. The cases have been coordinated in an MDL proceeding before Judge Fallon in the E.D. LA. Discovery is ongoing with the first trials anticipated in early 2017. In re: Xarelto (Rivaroxaban) Products Liability Litigation.
  • Lead counsel for Bayer Corporation in a case involving claims of toxicity against low dose aspirin. The case resulted in a complete victory for the client when Judge Real (U.S.D.C. Central District, Cal.) granted summary judgment on all claims in June 2016. Steen v. Bayer et al., C.D. Cal. (Reconsideration denied Sept 6, 2016.)
  • Currently acting as lead trial counsel for Philip Morris USA defending Engle class action progeny and non-Engle personal injury tobacco cases. In February 2016, a jury reached a unanimous defense verdict after deliberating for under two hours finding a former smoker’s lung cancer was not caused by her smoking. Pooshs v. Philip Morris et al., N.D. Cal. This verdict followed a series of successful verdicts in Engle progeny cases tried in Florida state and federal courts, including a June 2014 unanimous defense verdict. Surico v. Philip Morris USA Inc.
  • Currently acting as coordinating science counsel (working with national counsel) for the science defense in Zoloft cases for Pfizer Inc. These efforts have resulted in two significant Daubert victories for the client. Indeed, Ms. Yates was recognized for her thorough cross examination of the plaintiffs’ only causation expert in a week-long Daubert hearing (April 2014). On June 27, 2014, Judge Rufe issued an opinion and order stating that the “methodology and reasoning underlying Dr. Berard’s opinion is not scientifically valid and excluding all of the opinions as being based on a “novel methodology.” In Re: Zoloft (Sertraline) Products Liability Litigation, E.D. Pa. A second Daubert hearing took place in September 2015 when plaintiffs were permitted to substitute a new causation expert, Dr. Nicholas Jewell. As with the first expert, Ms. Yates cross-examined Dr. Jewell. After a three day hearing, Judge Rufe issued a second opinion and order, excluding this replacement expert.
  • Currently acting as co-national counsel for Endo Pharmaceuticals Inc. with her NY partner Andrew K. Solow, in product liability litigation, including an MDL, involving TRT (Testosterone Replacement Therapy) products defending against claims of heart attack, stroke and related cardiac issues.
  • Previously served as national and local counsel for Endo Pharmaceuticals Inc. and Qualitest in the successful defense of lawsuits relating to a recall of several oral contraceptive products. Ms. Yates coordinated all phases of the litigation and led her team to several successes, including successfully opposing formation of an MDL proceeding, and defeating three purported class actions in California, Georgia and Illinois.
  • Previously acted as national counsel for Pfizer Inc. in the HT litigation. Responsibilities include acting as lead trial counsel, creating, coordinating and implementing the science defense and handling all phases of litigation, involving several hormone therapy products.
  • In May 2012, Ms. Yates, along with Andrew K. Solow (Partner in the New York office), served as co-lead trial counsel for Pfizer units Wyeth, Inc. and Wyeth Pharmaceuticals Inc. in US District Court (Connecticut) and obtained a defense verdict on all counts related to a wrongful death suit involving Wyeth’s hormone therapy (HT) medications Premarin and Prempro. After a three-week trial, the jury dismissed all four of the alleged claims. This decision marks Ms. Yates and Andrew’s second win in less than one year regarding both HT medications. Lynn Gardner Moss, et al. v. Wyeth, Inc., et al.
  • In July 2011, Ms. Yates, along with Andrew K. Solow, served as trial counsel for Pfizer units, Wyeth Pharmaceuticals Inc. and Pharmacia & Upjohn Co., and obtained a defense verdict in a case involving claims of injuries from the client’s HT medicines. After a three-week trial, the jury found that the HT prescription medicines did not cause the plaintiff’s breast cancer and that the plaintiff’s claims were time-barred by the applicable statute of limitations. Notably, this was the first defense verdict for Pharmacia & Upjohn in the hormone therapy litigation. Hines v. Wyeth, et al.
  • Served as national and local counsel for Pfizer Inc. (Warner-Lambert) in the Rezulin (diabetic medication) litigation. Responsibilities covered all aspects of litigation. Ms. Yates obtained unanimous defense verdicts against all plaintiffs in the first in the nation consolidated plaintiff trial. All three plaintiffs claimed liver injury from exposure to the medication. This verdict was featured in The National Law Journal’s “The Defense Hot List: Sizing Up Defense Firms with Big Wins” (August 22, 2005).
  • Yates, along with others on the Kaye Scholer team, won an important Daubert victory in the Rezulin multidistrict litigation (2005 WL 583751 (S.D.N.Y.)). After a two-day hearing, the court ruled that plaintiffs could not rely on their proposed expert testimony that Rezulin caused a “silent” liver injury. Ms. Yates cross-examined the plaintiffs’ lead toxicologist, which was the focus of the court’s Daubert opinion excluding said testimony.
  • Acted as National Coordinating Counsel in the silicone breast implant litigation, representing Baxter Healthcare Corporation and Baxter International Inc. Responsibilities involved handling all phases of litigation, including trials. Ms. Yates obtained defense verdicts in two separate multiple plaintiff trials in Texas. All plaintiffs claimed defective implants due to rupture, negligence, failure to warn, strict liability and fraud. The juries returned defense verdicts on all claims.
  • Represented Wyeth Inc., defending their diet medications Dexfenfluramine and Fenfluramine in the Phen-Fen litigation. Specifically, Ms. Yates was responsible for deposing and defending expert witnesses, and developing national experts in the areas of cardiology and pulmonology.
  • Acted as national counsel for Merrell Dow Pharmaceuticals Inc., the manufacturer of Bendectin, an anti-nausea medication for pregnant women. She successfully defended the company against claims of birth defects, ultimately resulting in many courts excluding plaintiff’s expert evidence on the grounds of “junk science,” following her Daubert
  • The landmark case of Daubert v. Merrell Dow Pharmaceuticals, Inc., 727 F.Supp. 570 (S.D. Cal. 1989); aff’d 951 F.2d 1128 (1991); 509 U.S. 579 (1993). Daubert sets forth the standard by which judges are to act as gatekeepers in excluding “junk science” from the courtroom.
