What subject does MPEP 1400 cover?

MPEP 1400 specifically addresses the correction of issued patents.

Such corrections are crucial for ensuring that the patents accurately reflect the intended claims and that any mistakes, whether clerical or substantive, can be addressed after issuance.

The MPEP emphasizes the types of errors that can be corrected, the necessary documentation and forms needed to initiate a correction, and the relevant statutory provisions that govern these corrections. This helps to maintain the integrity and clarity of patent rights by allowing patentees to seek rectification when necessary.

Understanding the content of MPEP 1400 is essential for anyone involved in patent prosecution or litigation, as it provides guidance on how to navigate post-issuance corrections effectively and ensure that patents are both enforceable and reflective of the inventor’s original intent.
