In January 2010, the SAS Institute sued World Programming in the
US District Court for Eastern North Carolina for similar claims of violating the SAS Learning Edition licensing agreement by reverse engineering the software and infringing on SAS' copyright by developing the World Programming System. Based on the appeal, the US District Court for Eastern North Carolina granted
summary judgment denying the copyright infringement,
tortious interference with
contract, and tortious interference with prospective economic advantage claims. Additionally, the district court provided partial summary judgement granting the
breach of contract claim. The claims of copyright infringement of the SAS manuals, fraudulent inducement, and unfair deceptive trade practices were addressed in a
jury trial in late 2015. == US lawsuit (subsequent filing) ==
