Question: I filed a provisional patent for a guitar accessory. When can I approach a retailer to sell it? I've done my own searches for this product and none seem to exist. The product would solve a huge problem and is a very simple design. I would like the utility patent but was told it might be obvious. Not sure what that means
Answer: You can now approach retailers to sell it. However, the filing of a provisional patent application does not give you the right to stop infringers. And it does not mean you are not infringing another's patent.
