What are the consequences of inequitable conduct in patent prosecution?

The consequences of inequitable conduct in patent prosecution are severe. MPEP 2016 outlines that such conduct leads to the unenforceability of the entire patent. As stated in the J. P. Stevens & Co. v. Lex Tex Ltd. case:

“Inequitable conduct ‘goes to the patent right as a whole, independently of particular claims.'”

This means that if inequitable conduct is found, the patent holder cannot enforce any claims in the patent, regardless of which specific claims were directly affected by the misconduct. It’s a comprehensive sanction that emphasizes the importance of ethical behavior in patent prosecution.
