Hi all. Looking at importing and private labelling a type of bamboo chopping board from China to sell on Amazon in America. The surface of the chopping board uses one flattened piece of bamboo rather than gluing strips together to form the surface. There are a range of benefits to this. There are various patents out there that seem to cover this technology. Could anyone tell me whether i'd be infringing on any patent? If it is recommended that I speak to a lawyer, could someone please suggest how much something like this would cost to research?
