You're incorrect.
First, there are two types of patents: object patents and process
patents. In the case of an object patent, what is prohibited is the
production of the object.
Software patents are all process patents.
Using the process is certainly a violation.
But distributing a widget that with the intention that it be used to
violate is contributory infringement, and that's what happens if you
distribute a program that implements a patented algorithm.
