Charles ingram show...
Whittock has maintained the coughs were innocent |
The former college lecturer from Cardiff - who was found guilty of cheating on TV quiz show Who Wants To Be A Millionaire? - took action when he discovered that a company was going to launch a cough medicine called "Tecwen Relief".
But it could be several months before Mr Whittock finds out if his trademark has been granted and if there is any opposition to his application, there is a chance it could be refused.
Mr Whittock, 53, was found guilty by a jury at London's Southwark Crown Court of using coughs to lead Major Charles Ingram to the correct answers on the ITV1 quiz.

The damning episode is scheduled to be shown on ITV1 on Saturday.
