What is rejoinder practice in the context of product and process inventions?

Rejoinder practice is an important aspect of patent examination that allows previously withdrawn claims to be considered for allowance under certain circumstances. The MPEP 806.05(i) briefly mentions rejoinder:

“See MPEP § 821.04(b) for rejoinder practice pertaining to product and process inventions.”

Rejoinder practice is particularly relevant in cases involving product and process inventions. It allows for the reconsideration of process claims that were previously withdrawn due to a restriction requirement, if the product claims are found to be allowable.

For detailed information on rejoinder practice, including specific conditions and procedures, refer to MPEP § 821.04(b). This section provides guidance on when and how rejoinder can occur, which can be beneficial for applicants seeking broader protection for their inventions.
