Recently, a lawyer told me that if my company makes a product (in my case an electronic board) like another patented product on the market, but my product adds functionality to the original product, then my product would automatically be a “utility model” and not violate any patents.
But I read online that a utility model is itself a patent. And now I'm a little confused.
What is the real difference between a patent and an utility model?
Can my utility model can be replaced by another utility model?
My jurisdiction is Italy but the patented product may be protected by patents in other countries including US.
