It is said that mathematical algorithms aren't patentable. Sometimes it is not too clear what exactly constitutes a mathematical algorithm. If I have a powerful and unique technique/ process/ methodology (algorithm?) "invented" to perform a certain important calculation (on a hardware because of its intensive nature) that will be subsequently used to perform something valuable based on its output values, can that technique/ process/ methodology (algorithm?) and its usage be patented (or is it not patent eligible). It is a unique and powerful technique. If not patent eligible, society may not reap the benefits of my invention as I may not attempt patenting it, and hold back on it. And, that defeats the whole patent purpose. I am not sure if I should proceed to patent -- time, energy, and costs are high. I am a private individual and my methodology etc. is based on my personal research work at home, developing and testing the technique.
