2. It can be converted into a normal application.
3. If it is not required to be converted into a normal application within 12 months from the date of application, it shall be deemed as abandonment and may not be resumed.
4. Ordinary applications can claim the priority of temporary applications, and vice versa.
Only inventions can enjoy the priority of temporary application, and there is no temporary application for design.
