Barry E. Bretschneider

Barry E. Bretschneider is a Senior Counsel at Whiteford, Taylor & Preston LLP with a practice focused on patent infringement litigation and other intellectual property disputes. His firm history includes partnerships at BakerHostetler and Morrison & Foerster. Bretschneider's litigation experience spans U.S. district courts and the International Trade Commission (ITC), where he has handled cases across a wide array of technologies, including electronics, semiconductors, medical devices, pharmaceuticals, polymers, and automotive systems.

While the tracked case list shows a single appearance for a plaintiff, Bretschneider's broader practice involves representing both U.S. and foreign corporations on both sides of the docket. His representative work includes defending a medical device manufacturer's patents on DNA amplification technology in a reexamination proceeding, which resulted in the confirmation of all patent claims. He has also successfully represented an electronics manufacturer in two ITC trials, leading to decisions that confirmed the validity of his client's patents. Another notable outcome involved securing a favorable Markman claim construction ruling that led to the dismissal of an infringement action with prejudice.

In addition to litigation, Bretschneider is experienced in post-grant proceedings before the U.S. Patent and Trademark Office, including inter partes review (IPR), reexaminations, and interferences. His practice also covers patent prosecution, licensing, and related transactional work. He is a registered patent attorney.

According to his public bar records, Bretschneider earned a law degree from the University of Iowa and a Master of Laws from George Washington University School of Law. He is admitted to practice in Virginia, the District of Columbia, and Texas, as well as before numerous federal courts, including the U.S. Court of Appeals for the Federal Circuit and the Supreme Court of the United States.
