Whenever decision makers in enterprises believe their law department will handle protection of intellectual rights, they might be true. Probably they are false.
Possibilities of protection have increased in the last decades. Law systems in UK and the US differ from those in Europe or Asia.
Whether it is a corporate colour or form or just graphic elements or combinations – these assets can be protected as trademarks. (And in Europe or Asia they are not “automatically” protected following their usage – the “TM” hasn’t any legal status on those continents.)
The most effective way of finding a well protected corporate design is to know a CD-Agency which knows the possibilities and is trained to work in the right – protectable – direction.
