(I'll reserve comment on the basic assumption in both Philippe and
Chris's posts that the legal enforcement of an "open source" trademark
is vital, which for reasons amply discussed over the years is
simply fallacious -- making Philippe and Chris's entire line of
reasoning from that point forward a waste of time.  Suffice it to say
that I concur with Matthew Flasche's separate post on that matter.)

To be blunt, Philippe's views seem no better informed on this matter
to what they were the last time he opined about it in October.  At that
time, it was extremely evident he needed to learn some trademark law,
and also (in particular) unlearn some fallacies, e.g., his bit about
OSI needing to become "the legal owner of the expression" (a meaningless
phrase in trademark context).

Above, Philippe asserts that OSI could not be correctly asserted to own
an "open source" trademark (and no, capital letters are _not_ required)
without "registration", e.g., with USPTO.  Sorry, wrong.

I cannot speak to EU member-states' trademark regimes (it having been a
while since I've read up on those), or other countries', but, in USA
law, registration is not required for a trademark to exist and be
enforceable.  In the USA, one establishes title to a mark _either_ by
being first to use the mark in commerce[1] within a given trade or
industry, or being first to register it for that trade or industry with
USPTO.  The former method is called a common-law trademark, the latter a
Federal one.  Philippe's implicit assumption that the former lacks force
is simply false.  Wrong.

(The annoying thing is that we've already _had_ this discussion, some
months ago.)

Federal registration confers these advantages:

1.  Nation-wide enforceability, as opposed to only in regions where
    the mark has been used (15 USC 1072).
2.  Establishes contructive notice to third-party users of one's claim.
3.  Ability to bring enforcement action in Federal (as opposed to state)
    court (15 USC 1121).
4.  Status of "incontestible" after five years.

Common-law trademarks are every bit as enforceable as are Federal ones;
they simply don't entail the above-cited advantages.

This whole bit is irrelevant:  Philippe seems to be confusing copyright
and trademark law.  (Perhaps this is the revival of Philippe's October
2007 notion that trademark is "the legal owner of the expression".)

No, wrong.  That is not what trademark is.

No, wrong.  The same phrase can be and is registered at (e.g.) USPTO by
different entities in different classes of goods or services.

No, this is not quite right, either.  Again, Philippe still needs to
read and understand some trademark law -- same as four months ago.

We could go on, but I think that's rather enough for now.
