I am wondering if I can patent in the US a handmade toy that I saw in Brazil. It is not patented in Brazil I believe.
I do however, have a few improvements on the original design, but the rough idea is the same. Could I file for a provisional patent and be able to sell the idea to companies in the US, or the fact that the rough idea is the same prohibits me from trying to go for the provisional patent?
Thank you.
