Further, amongst other things, generally any words importing the masculine gender include the feminine and words in the singular include the plural and words in the plural include the singular.

(c) Section 123(2A) of the Patents Act allows the comptroller to give directions specifying any forms the use of which is required by the Patents Rules.

(d) Patents form 4 has been introduced and patents form 17 has been revised, as set out below.

2.2 Patents form 4 (Continuation of proceedings before the Comptroller)

(e) Patents form 4 has been introduced as a result of amendments to the Patents Rules 2007 and the Patents (Fees) Rules 2007. These amendments are made by the Patents and Patents and Trade Marks (Fees) (Amendment) Rules 2010, which come into force on 6 April 2010.
