Date Published

Note: The information in this part applies to all standard patent applications and innovation patents.

The starting materials of a chemical process, or ingredients of chemical compositions, must be known compounds.  Alternatively, a method of preparation of those compounds from known materials should be either disclosed in the specification or otherwise evident. A statement in the specification that a compound is obtainable, or otherwise known, should generally be accepted. Reference to a compound by a trade name or by another commercial identification, whilst possibly unsatisfactory in other respects, may be considered as a prima facie indication that the compound is known (see also Trade Marks in Specifications).
