My client runs a small service, repair and custom build center for American motorcycles most Harley Davidson & Buell.
We are looking at setting up a PPC campaign but am wondering how careful we would have to be as HD is trademarked so am I right in thinking that we cannot use this name in the ads, if so what would be use as they wish to generate business for customers looking for 'Harley Davidson....repairs, servicing, custom modifications ect'.
American motorcycles, HOG ( yes I know it is Harley Owners Group..but it may not be trademarked ? and everyone knows what it means if they ride bikes :)..VTwin V Twin..Vee Twin ..
The technique of getting a particular groups attention without doing it openly is known as "the silent dog whistle"..usually a political technique..but can be a way around trademark issues if one isn't an official dealer, garage etc....
legal advice it isn't..you can't get that here....not from fora, you'd need a lawyer..
but the above might give you some ideas of what might or might not be trademarked..
I'm pretty sure that "rollin' thunder" or "rolling thunder" is trademarked..
