Hi Ted,
I believe you are right.
Let me further add a) it's IMO foolish to attempt to force re-examination
without a *good* patent lawyer (even if it's allowed in the US), and b)
that, AFAIK, this aspect of the perceived brokenness of the patent system is
not local to the US.

The mechanisms to challenge the validity of a patent depend on the
legislation. In the US, one example is a request for re-examination. A
good foundation for such a request would be the presence of Prior Art not
considered during the prosecution phase. The effort and cost involved is
significant and can be compared to the prosecution of a patent. One problem
with re-examination is that one has to show that the patent office was wrong
in issuing the patent originally. That is, one does not only fight the
interests of the rightholder, but also the established opinion of the patent
office. No one likes to be proven wrong, and, therefore, re-examination is
often an uphill battle against an established bureaucracy.
Worse yet, if you don't have all of your expensive patent lawyers
lined up, and the patent office decides it doesn't want to admit that
it screwed up, the patent actually ends up being *stronger* afterwards
--- that is, a patent which survives a re-exam is presumed by the
courts to be more likely valid.
This brings up an interesting strategy by patent trolls to secretly
get a sock-puppet to deliberately launch a incompentent patent
re-examine, just to make the patent appear stronger. As a result,
some patent attorneys, upon examination of the unique facts of a
particular patent, might decide that it's better to not try to
challenge the patent, and wait for the troll to make the first strike.
It's amazing how screwed up the US Patent system is, isn't it?
