Some logo design elements have been used so many times that they can no longer be claimed as original creations, and thus will probably not be eligible for trademark registration. These outdated-looking symbols are labelled "generic".We discourage this type of work on Designhill. We also reserve the right to terminate the accounts of designers whose work does not meet our quality standards.
Please refer to our official article on Generic and Common logo concepts here. It is a MUST read for all the designers participating on Designhill.
