I'm not American, so the US patent law is not relevant to me.
The thing I'm stuck with is the patentability of my inventionـwhether my invention can apply for a patent or not.
Basically what I did was that I reverse-engineered a product existing abroad, with a registered patent in Europe and the US, improved it by making some sort of modification to the core of how it functions, which gives users better options and ease of use.
Some other improvements I put are secondary, giving the entire product a different design that, in a big part of it, is not relevant to the claims of the existing invention abroad.
This product has a valid patent registered in the US as well as in Europe. I live in north Africa, and I intend to register my product that is improved in my country. Literally there are no local patent attorneys I can ask. I'm still wondering if my product is eligible for a patent or not, or at least if I have a chance.
Need someone who know about patent infringement to help me with this, and I'm ready to give more details if needed.
