In the recent case of Ratiopharm Inc v Pfizer Limited (2009) FC711 Mr Justice Hughes has again emphasised the important of exercising the utmost good faith in the drafting and prosecution of patent applications. In this chemical case, he was highly critical of the draftsperson for including phrases such as "unexpectedly", "unique", and "outstandingly suitable" as being "self-serving" and inconsistent with the facts apparent from the record of the invention. Hughes found that the words could not have come from the inventors, but "could only have come from the Pfizer patent department".
