If the application does not satisfy the legislative requirements, the examiner issues a written examination report, which sets out any deficiencies as Office action. The applicant may respond to the written report by filing amendments to the application to overcome the objections.
The examiner must then reconsider the application in the light of the applicant’s response. If any office action remains unresolved, the examiner issues another report. If the applicant does not comply with the office action within the given time the application will lapse.
When the application is free of objections (either at the beginning of examination or as a result of an applicant’s response to report), the examiner is obliged to accept the application. The acceptance is then advertised in the Official Gazette.
