The Hasbro v MAPS Toys Yummy Dough trial started yesterday with several industry figures appearing.
The High Court trial is expected to last six days, with Hasbro arguing the MAPS' use of the word 'dough' in its Yummy Dough line, infringes it own Play-Doh copyright.
The Entertainer's Gary Grant was Hasbro's expert witness with Gemma Harding from Tesco, Rosanne Pearce from WH Smith and Mark Campbell from Hamley also among the claimant's witnesses in chief.
