[kwlug-disc] OOXML and i4i patent litigation

I stand corrected!

Reading the first pages of the complaint and reviewing the products offered by i4i, it seemed to me that they were referring to a method of editing XML. After reading the full patent it was clear that in reality it is a method for mapping the document content to metacodes instead of having them "in-line" describing the document.

I still think that the patent is frivolous.

Mapping data has existed for as long as I remember. This is, for example, the main way of interpreting and formatting fixed column data.

Actually the "advantage" of XML versus mapping was that the document contained both. Here it seems that they separate the content and the mapped metacodes, while still providing them in the same document.

It's my understanding that OOXML contains technology covered by the
I4i patent, and as long as Microsoft disables that specific feature
("custom XML?"  I'm unclear as to the exact feature), then they can still
sell Word that reads and writes a subset of OOXML.

What am I missing?
