11.2 When can I submit a Post-Grant Amendment?
Patentees of inventions or designs may file a request for amending the description, claim(s) or drawing(s) after a patent right is granted on the publication date of the patent.
Patentees of utility models requesting to amend a utility model patent should do so only within the specified time periods, i.e., where “a request for a technical evaluation report of the utility model patent is pending” and where “a litigation case involving the utility model patent is pending.”
