Barbara L. Mullin has been litigating cases in federal courts and before arbitration panels for more than 20 years.  Her cases have involved diverse technological fields such as recombinant antibodies, medical devices and methods, pharmaceuticals and semiconductor wafer processing. 

Practice & Background

Ms. Mullin is routinely responsible for developing strategic litigation positions as well as the trial examination of expert witnesses in high profile cases.

In the biologics area, Ms. Mullin was responsible for the direct and cross examination of technical experts as part of a trial team that won a jury verdict for client Janssen Biotech Inc. in a patent infringement suit brought by Abbott GMBH & Co.  In that case, the jury returned a verdict that claims in two patents asserted against Janssen’s antibody drug product, Stelara®, were invalid.  Ms. Mullin was also responsible for the direct and cross examination of technical experts as part of a trial team that won a $1.67 billion jury verdict in the Eastern District of Texas for clients Centocor Ortho Biotech, Inc. and New York University.  This patent infringement suit was against Abbott Laboratories’ flagship product, Humira®. The jury returned a verdict that the patent-in-suit was willfully infringed and not invalid. The $1.67 billion verdict was reported by Bloomberg to be the largest patent jury verdict in U.S. history.

In the medical devices area, Ms. Mullin was responsible for the direct and cross examination of technical experts in a case brought by Tyco Healthcare Group LP against Ethicon Endo-Surgery, Inc. concerning ultrasonic surgical instruments.  This case followed an earlier suit where Ms. Mullin successfully argued an appeal to the Federal Circuit on a threshold issue that substantially benefitted her client in this second trial.

Ms. Mullin also has substantial experience in evaluating ANDA issues and led a team of attorneys in defending against claims in multiple ANDA litigations where she is representing her client’s interests in defending against these claims.

Ms. Mullin is also a guest lecturer in Patent Litigation at the University of Pennsylvania School of Law and the Temple University Beasley School of Law.

Ms. Mullin received her J.D. cum laude in 1991 from Villanova University School of Law and served on Law Review.

Ms. Mullin supports several pro bono activities, including the Support Center for Child Advocates and the Equal Access to Justice Campaign of the Philadelphia Bar Foundation.
