The strategic use of fuzziness in patent specifications

Innovators seek to protect their intellectual assets by patenting them, at the same time trying to avoid any disclosure of critical knowledge.

This paper provides a model identifying the incentives for firms to deliberately obscure their inventive knowledge in a patent specification.
