It's not on that level. The patent is just about a specific internal
representation of a marked up text: separate the text and the markup,
such that the text is just a contiguous string and the markup is in a
list (array) with pointers to the text. And about the conversion between
the external representation with the markup embedded and the internal
representation described above. And about making changes to the text and
the markup independently. And a few things related to that, for
example having two or more of these structures on the same text where
the text will be shared.

Weave and tangle do more than that. Moreover the patent applies in the
context of a textprocessor (i.e. an interactive program), and weave and
tangle are not that.
