A case decided 2 years ago by the U.S. Supreme Court called Bilski v. Kappos greatly affected the patentability of different types of methods, particularly business methods and software. To patent your method, it must either (1) be implemented with a particular machine, that is, one specifically devised and adapted to carry out the process in a way that is not concededly conventional and is not trivial; or else (2) transform an article from one thing or state to another. In addition, as mentioned, algorithms themselves are not patentable. You should consult with a patent attorney to see if there is some aspect of your invention that may be patentable.
