I seen a business for sale that i'm interested in but curious if there are legal/trademark issues. The business has cartoon characters and people can rent them out for parties and the characters show up and dance and play games etc... Now i asked the owner if they've had any issues with them and they stated that the characters have to be a certain percentage different then the original character ie: donald duck, mickey mouse etc... The characters are not named the same, but look like them. Now i'm looking for some help is this worth it, or am i looking into trouble???
