Prior art made available by means of oral description 

If the prior art was made available to the public by an oral description before the relevant date (i.e. the date of filing of the application or, if applicable, the date of the earliest validly claimed priority) but a document which reproduces the oral description was only published on or after that relevant date, the ISR and the IPER draw attention to this non-written disclosure in the manner provided for in Rule 70.9 (Rules 33.1(b) and 64.2).
