Bijan Esfandiari | Wisner Baum Senior Partner

Bijan Esfandiari joined Wisner Baum in 2007 as a pharmaceutical product liability attorney. Since his arrival, Bijan’s legal work has helped shape and develop the law for the benefit of those harmed by pharmaceutical and medical devices.

A 2002 graduate of UCLA School of Law, Bijan spent the first five-years of his legal career as a defense attorney at a major national law firm working on a variety of cases spanning multiple disciplines including entertainment law, intellectual property and toxic torts. Discontent with representing corporate polluters and recalling he went to law school to help those who were harmed by the greed and neglect of others, Bijan joined Wisner Baum where he found a committed group of lawyers and colleagues who were dedicated to helping those who were injured and harmed by corporate malfeasance.

During his time at Wisner Baum, Bijan has worked as lead counsel on several cutting-edge pharmaceutical and medical device cases wherein he has helped thousands of clients obtain compensation for injuries they sustained because of defective drugs and devices. Utilizing the discovery process, Bijan has obtained internal corporate documents demonstrating that pharmaceutical manufacturers intentionally hid and concealed dangers associated with their products simply to maintain sales and profits. As way of example, in one case after examining the evidence Bijan had obtained and submitted to the Court, the Court held: “internal GSK documents suggest that Defendant acted with a wanton and willful disregard for the safety of its consumers. Given such evidence, Plaintiffs may be able to establish at trial that Defendant knew of the risks of pediatric use of its drug yet failed to warn solely to increase the commercial profitability of Paxil.” The ruling allowed Bijan’s clients to proceed with claims for punitive damages and resulted in a successful resolution of the case.

Bijan routinely works on challenging cases involving severely injured clients which other firms refuse to handle due to the costs and legal hurdles associated with such cases. His efforts in this regard have resulted in not only helping individuals others in the legal community declined to represent, but in the process Bijan’s efforts have led to precedent setting legal rulings that have benefited all plaintiffs and consumers.

Many of these precedential successes came in the form of defeating pharmaceutical and medical device companies’ claims that they are immune (preempted) from liability by virtue of their products being approved by the FDA. In 2014, Bijan successfully briefed and argued the first and only medical device preemption case at the time before the Maryland Court of Special Appeals. In an issue of first impression, the three-judge panel in McCormick v. Medtronic, Inc., 219 Md. App.485, unanimously agreed with Bijan’s arguments that the device manufacturer was not entitled to immunity and held that plaintiff could proceed with his claims against the medical device manufacturer. This appellate success led to thousands of other similarly injured plaintiffs being able to successfully bring and maintain claims against the device manufacturer.

In a similar proceeding, Bijan successfully briefed and argued the first drug preemption (immunity) case before the United States Court of Appeals for the Seventh Circuit. The three-judge panel in Mason v. SmithKline Beecham Corp., 596 F.3d. 387 unanimously agreed with Bijan’s arguments, finding that plaintiffs’ claims against the drug manufacturer were not preempted by federal law.

The significance of these and other landmark rulings cannot be overstated. They ensure that drug and medical device companies who engage in deceptive or impermissible conduct are not entitled to immunity and that they can be held accountable in a court of law for any injuries they or their products cause to consumers.

The son of an infectious disease scientist, Bijan has always been surrounded by members of the medical community from a young age. In addition to the joy he receives from representing and obtaining justice for his clients, a favorite part of Bijan’s legal practice is that it allows him to learn from some of the world’s top medical experts in their respective fields, retained in the pharmaceutical and medical device cases he handles.

Aside from obtaining substantial monetary recoveries for his clients, the cases Bijan and his colleagues at Wisner Baum have worked on have resulted in the public and medical community learning about previously undisclosed risks associated with select drugs, devices, and products, and in certain instances the litigations have resulted in labeling changes being implemented or dangerous products being removed from the market to prevent future consumers and patients from suffering the same harms.

A prolific writer and courtroom advocate, Bijan has had several of his cases published, including but not limited:

Riera v. Somatics, LLC, 800 F. App'x 537, 538 (9th Cir. 2020)

Hricik v. Stryker Biotech, LLC, 89 F. Supp. 3d 694 (E.D. Pa. 2015)

Boutte v. Stryker Biotech, LLC, 67 F. Supp. 3d 732, 734 (M.D. La. 2014)

Dorsett v. Sandoz, Inc., 699 F.Supp.2d 1142 (C.D.Cal. 2010)

Tucker v. SmithKline Beecham Corp., 701 F.Supp.2d 1040 (S.D.Ind.2010)

Mason v. SmithKline Beecham Corp., 596 F.3d 387 (7th Cir. 2010)

Forst v. SmithKline Beecham Corp., 602 F.Supp.2d 960 (E.D.Wis. 2009)

Knipe v. SmithKline Beecham, 583 F.Supp.2d 602 (E.D.Pa. 2008)

Tucker v. SmithKline Beecham Corp., 596 F.Supp.2d 1225 (S.D.Ind. 2008)

Throughout his career, Bijan has received numerous awards and recognition, including:

Timothy A. Loranger | Wisner Baum Senior Partner
