Article 3 Citation and commencement

For rule 22 there shall be substituted the following—

“Unity of invention

22

(1)

Without prejudice to the generality of section 14(5)(d), where two or more inventions are claimed (whether in a single claim or in separate claims), and there exists between or among those inventions a technical relationship which involves one or more of the same or corresponding special technical features, then those inventions shall be treated as being so linked as to form a single inventive concept for the purposes of the Act.

(2)

In this rule, “special technical features” means those technical features which define a contribution which each of the claimed inventions, considered as a whole, makes over the prior art.”.
