"Computer programs, though often protected by copyright or trade secrets, cannot be directly patented unless they are used for something tangible, such as signal processing or hardware control,..."
Look at eg. United States Patent 6,859,816 Makino, et al. February 22, 2005, (assignee: Sony Corporation), filed January 25, 2001. This seems to be a patent for a case of the Fast Fourier Transform. The patent mentions nothing more tangible than an algorithm.
