I am in Illinois. I work for a print advertising company that usually runs ads for small businesses. Once in a while, we'll get a small business who wants something like Jiminy Cricket in their ad, 99% likely they never got permission. I understand that this is wrong, and that companies such as Disney have actually sued small business owners for using their intellectual property, but would the company I work for be responsible for running an ad that the CUSTOMER requested use property that is not his?
