As I currently interested in Machine Learning, a lot of research paper proposed algorithms.<p>My concern is how do I know if the algorithm was patented?<p>I want to (but not yet) implement some algorithms based on research paper to play around.
I was under the impression that algorithms couldn't be patented, even in the US. Only software implementations (in the US) or devices using them. Algorithms are just maths.
