Sandra J. Wunderlich

St. Louis, MO | D 314.256.2544 | F 314.256.2549 | M 314.323.7967

Sandy Wunderlich has a diverse litigation background, with particular emphasis on intellectual property consulting and litigation.

An experienced trial lawyer, Sandy has been lead trial counsel in a dozen jury and bench trials. Over the past 25 years, she has litigated patent, trademark, copyright, and domain name matters from the cease-and-desist stage through appeal. A member of the Federal Circuit, she has successfully handled appeals in that court. Outside of litigation, she provides intellectual property consulting on the likelihood of litigation and strategizes with clients on ways to avoid it.

Sandy has represented large pharmaceutical manufacturers, agricultural and industrial manufacturers, a Fortune 50 company, and large national banks and credit arms of Fortune 100 companies in areas including mass tort and product liability, medical device and pharmaceutical liability, financial services litigation, and in other complex litigation. She also defends clients in individual or class actions alleging violations of the Illinois Biometric Information Privacy Act, which regulates the use of employees' biometric data, such as fingerprints, voiceprints, retina scans, and facial recognition technology.

Sandy has litigated intellectual property disputes in Missouri, Kansas, Delaware, Minnesota, Illinois, Tennessee, California, Texas, and Ohio, and has appeared in other states including Florida, New York, and New Jersey in other matters. Sandy handles appeals in the highest appellate courts at both the state and federal level.

Early in her career, Sandy served as the first judicial clerk to the Honorable Elwood L. Thomas of the Missouri Supreme Court. There, she established procedures for reviewing appellate briefs, evaluated writs seeking extraordinary relief, prepared outlines for Judge Thomas to use during oral argument, and researched and drafted opinions at his direction.
