This paper aims at analyzing the risk of whether to acquire a patent non-infringement opinion. After Seagate, there have been many decisions of either district courts or Federal Circuit involving willful infringement. This paper discusses some observations from those decisions. The observations give a basis for thinking of whether to acquire a patent non-infringement opinion. The analysis is presented in view of a potential or accused infringer, Company T. Company T could be accused of direct or indirect infringement. By discussing either Federal Circuit’s or district courts’ cases after Seagate, this paper suggests that though there is no duty to get a patent non-infringement opinion, the best strategy for an accused infringer would still be to have such opinion letter.
