I have an idea about a way to sell flip flops. I`ve seen numerous companies sell the same kind of flip flops, so should I assume that there is no patent on them? I`ve even seen the same flip flops on China`s manufacturing websites. If I add my logo to it, does that make it different enough? I definitely don`t want to infringe, but to me the flip flops are like clothing, a common thing. Any thoughts and comments are greatly appreciated!
