Due to the changes in the Singapore Patents Act, there is a requirement for examined claims for applications having a filing date on or after July 1 2004, at the time of paying the grant fee. In particular, it is required that each claim in an application is related to at least one claim that has been examined and referred to in an examination report relied upon. Under section 2(4)(a) of the Singapore Patents Act, the definition of one claim being related to another claim is if the two claims are identical or (A) each limitation in the second claim is identical to a limitation in the first claim or (B) differs from a limitation in the first claim only in expression but not in content.
