Lauren Cohen, Umit Gurun, and Scott Duke Kominers study the determinants of, and consequences of, lawsuits by non-practicing entities (NPEs) alleging that operating firms have infringed on the NPEs' patents.

They also report a negative effect of NPE litigation on the target firm's subsequent innovative activity.
