As you are aware, Fangxing solar photovoltaic roof tile is using trademark Duer™. We allow all dealers and agents to make reasonable use of the ‘Duer’ trademark. For example, if you are going to distribute Fangxing solar roof tile, you can call it ‘Duer’. If you want to use the name in some other way, you should ask us first.
To be fair to all businesses, Fangxing insist that no business use the name ‘Duer’ in the name of the business, or a domain name of the business.
