The application can also file a request for expedited examination of the application under Form 18A.

Step 7 – Responding to objections/examination report

The applicant is required to submit a written response to the raised objections in the examination report. The applicant can argue regarding the patentability of the invention and try negating the objections being raised by the examiner.
