I can't find any better details on this. For now, PDF is an open format, and Adobe should have nothing to say about who implements it in their products as long as trademark restrictions are obeyed.

The .pdf issue may be the least of Adobe's concerns. Microsoft has made freely available a suite of three extremely powerful graphics and Web-design programs in beta form under the Microsoft Expression brand name.

The Microsoft Office 2007 Pro Beta 2 suite is also available for free download. Very buggy but nice looking, and still includes .pdf output.

So virtually every variation of word processor can have pdf files except Microsoft?

I don't get the reasoning.

Adobe has a rather tight needle to thread. They don't want to prevent people from writing software that writes to PDF, lest some new standard arise and supplant it, but they want theirs to be the one that's easy to use and well-known. Preventing Microsoft from doing the latter without preventing various third-party developers from doing the former could be tricky.

Adobe should lose this case easily, Open Office and Mac uses PDF.. unless Adobe removes support from those programs/systems... MS can use it too.
