That term should not be used. It obscures the issues. The real issue is what processes should be patentable.
Patent law allows for patents on processes.
It is irrelevant whether the process is done by hand, by special hardware or by a programmable device given directions by a computer program. Suppose one had a new method for making steel. The method defines the materials to use, the relative portions of the materials, and the sequences and timing for the materials to be put into a blast furnace. The fact that a computer program is used to control this process is not relevant to the issue as to whether or not this process should be patentable. Suppose that one has a new method for improving the manner in which access to a computer memory is allocated and controlled.
