Gregory P. Teran


Teran, Gregory P.

Mr. Teran's practice focuses on intellectual property litigation. His cases have involved a variety of technologies, including medical devices, pharmaceuticals, semiconductor processing techniques, integrated circuit design, software, computer networking and communications, graphical user interfaces for smartphones, and signal power detectors. Mr. Teran's experience includes ten trials in patent, trade secret, trademark and commercial cases in federal and state courts. He also previously served as a Special Assistant District Attorney in Middlesex County, where he tried 13 criminal cases to verdict and argued more than 20 dispositive motions. 

Mr. Teran has also represented indigent criminal defendants pro bono in Quincy District Court. He has provided trademark and copyright counseling to non-profit organizations. He currently assists veterans seeking benefits for combat-related injuries sustained in Iraq and Afghanistan.

In 2008, Mr. Teran served on a team of WilmerHale lawyers, led by Stephen H. Oleskey, that represented six Algerian-born men seized in Bosnia shortly after 9/11 on suspicion of plotting to attack the American embassy in Sarajevo and travel to Afghanistan to take up arms against the United States. Over the course of nearly 50 hours of classified pretrial hearings, Mr. Teran submitted and argued motions seeking discovery and exculpatory evidence, and co-tried the first-ever Guantanamo habeas corpus trial. The presiding federal judge held that five of the six men be released and urged the Government not to appeal.

Prior to his legal studies, Mr. Teran served as a lieutenant in the US Air Force.
