I intentionally quoted the patent law without interpretation.  At least some
of the follow-on questions you raise should be directed to your own
attorney, in the context of a specific set of facts for specific software,
for an authoritative answer.

The patent act does not define "publication" but the copyright act does:

  "Publication" is the distribution of copies or phonrecords of a work
  to the public by sale or other transfer of ownership, or by rental,
  lease, or lending.  The offering to distribute copies or phonorecords
  to a group of persons for purposes of further distribution, public
  performance, or public display, constitutes publication.  A public
  performance or display of a work does not of itself constitute

There is probably case law to interpret the word "publish" in the context of
the patent law but I'm not able to do that research for you now.  I'm sure
there is also case law to define what is meant in the patent law by "use."
