Since the patent system is intended to provide incentives to inventors, growing application numbers seem to bode well for innovation. Increasingly, however, economists criticize the patent system for actually hampering innovation, in particular in the context of cumulative and complex technologies. For current mobile phones, e.g., it has become next to impossible to identify all patents infringed upon by the product. Uncertainty, cost, and potentially lengthy licensing negotiations and infringement suits result. The above problems are partly inherent to the nature of complex technologies such as ICT, and have been extensively researched. In contrast, comparatively little is known about how patent applicants compound these problems by pursuing filing strategies that provide private benefits to them, but cause a welfare loss to society. While such strategies are perfectly legal, they thwart the purpose of the patent system by hampering rather than
