What is the utility requirement?
One of the requirements for obtaining a patent is that the invention must be useful -
it must have some utility. While you cannot simply claim that the
invention may lead to other innovations, this is not a difficult requirement to
meet. For example, the invention need not work better than other methods/inventions
designed to meet the same goal. Similarly, the invention does not have to
have any actual commercial value.
You only need to show
such utility if you are seeking a utility
patent - something does not have
to have utility (i.e., be useful) to be entitled to adesign patent or a plant
patent.
