Models and specimens of the new inventions usually are not required in the application for Patent Registration in Singapore. The applicants are required to furnish a patent specification containing a set of descriptions, a claim, and a drawing, if any, related to the invention. Any examination would be based on the patent specification filed by the applicant. However, if the invention involves the use of micro-organisms, he/she would be required to deposit a sample of that same micro-organisms. Singapore is a party to the Budapest Treaty (Treaty on the International Recognition of the Deposit of Micro-organisms for the purposes of the procedure of Patent conducted at Budapest in 1977). Therefore, the applicant can deposit a sample of the micro-organisms with any one of the international depository authorities, as stated under the Budapest Treaty.
