Trade Marks: Changes to Calculation of Deadlines at the UKIPO

On 31 March 2013 a number of rule changes came into effect that affect the way in which the UKIPO calculates some deadlines in relation to United Kingdom trade marks.

Most significantly, these changes have the effect of increasing the time period for filing an opposition against a United Kingdom trade mark application by one day (eg the opposition period for an application published on 11 April 2013 will expire on 11 June 2013, rather than on 10 June 2013 as was previously the case).

The new method of calculating deadlines applies to any deadlines that expire on or after 31 March 2013. The full notice is available on the IPO website.
