A further official letter was issued by the Omani Patent Office on 1st November 2017, requesting that applicants pay the substantive examination fees in respect of all patent applications which were formally accepted during 2016. It is therefore now necessary to submit a request for substantive examination and pay the examination fees within two months from the date on which the above-mentioned official letter was issued, i.e. before 1st January 2018. Failure to do so will cause the application to be considered to have lapsed. We will write to our clients on any cases for which action is required in order to comply with the above provisions.
