Headnote:

Rule 88 EPC does not apply to a non-obvious correction of an error in the description or claims which results from an erroneous technical calculation. A correction of such an error is allowable under Article 123(2) EPC if the amendment would be regarded by the skilled reader as clearly implied by the disclosure of the application as filed. If more than one arithmetical possibility of correction can be envisaged, the correction chosen must be the one which the application as a whole clearly implies.
