1826 The Abstract 

The abstract must consist of a summary of the disclosure as contained in the description, the claims and any drawings. Where applicable, it must also contain the most characteristic chemical formula. The abstract must be as concise as the disclosure permits (preferably 50 to 150 words if it is in English or when translated into English). National practice also provides a maximum of 150 words for the abstract.

The PCT range of 50 – 150 words is not absolute but publication problems could result when the PCT limit is increased beyond the 150 word limit.
