Mr Cook's lengthy battle about Push and Pull Signs

BGUK_1249291 - In 2009, Mr Cook began designing picture signs to depict PUSH and PULL, after taking four attempts with the doors to get into a coffee shop. The first designs were yellow, black and white. The designs had a curved arrow on a picture of doors opening different ways. The designs were protected with the system of European Registered Designs. In the background, ISO started creating their own designs using modified versions of Mr Cooks published Registered Designs. Mr Cook immediately sought legal advice, beginning what has become a David and Goliath lengthy legal battle involving BSI and ISO, and more recently the Crown Prosecution Service (CPS).
