[Zope] Zope hurt by Interwoven patent?

[Marcin Kasperski]

Does anyone know whether (and how) Zope itself and Zope users can have
problems with the new Interwoven patent?

Crucial part:

The claims include, 'The use of a hierarchical file system and an
object repository for representing and hosting content and its
structure,' and 'The combined concepts of file history, versioning,
comparison, and merging as it relates to content, provide an archive
of all individual changes as well as collections of changes so they
can be versioned and audited.'
