Trademark rectification is a legal process for correcting errors or omissions in trademark registration. This process can be started by the trademark owner or any interested person who believes a registered trademark was submitted improperly or that adjustments are required to update the register. Common causes for rectification include typographical errors, erroneous information about the proprietor’s identity or address, or non-use of the trademark for an extended period, rendering it eligible for cancellation. The rectification process includes submitting a petition to the appropriate trademark authority and giving evidence and arguments for the required changes. Successful correction ensures that the trademark register is accurate and reliable, protecting trademark owners’ rights and preserving public trust in the trademark system.
