Attorneys last week engaged in oral arguments at the U.S. Court of Appeals for the Eleventh Circuit in a nearly 13-year old case in which Boeing is accused of breaching contracts and misappropriating trade secrets related to their work in maintaining military tanker aircrafts for the U.S. Air Force.

Alabama Aircraft Industries, also known as Pemco Aircraft Engineering Services, sued Boeing in 2012 with a misappropriation of trade secrets claim and two breach of contract claims. The contract included both a Memorandum of Agreement (MOA) and a Non-Disclosure Agreement (NDA), and was struck after the two parties began conversations about jointly bidding to perform maintenance work on the Air Force’s KC-135 Stratotanker fleet.
