Sorry, I wish I did have something about this Philips protocol to tell you.
Hopefully someone more informed about it will respond.

But your question brings up something that really irks me:  I am looking at
doing a project using Philips I2C Bus and, through a series of phone calls,
happened to end up talking with the Philips in-house patent attorney about
it.  He told me some news that disturbed me:  he said, and I paraphrase
fairly close to the original - ' I won't say thay Microchip is breaking the
law using I2C YET, but they do not have a valid license.'  He then allowed
me to 'guess' (he wouldn't tell me outright) who all that manufactures of
microcontrollers that does have a license - virtually every one I could
think of (about 15-20).  he said he couldn't tell me much more about it yet,
but that 'Microchip will try to tell me differently'.  I, of course,
contacted MCHIP and they told me they DID have a license.  It worries me,
though, as the Philips Attorney told me he would certainly get something in
writing from Microchip stating they will back their claim to the I2C license
before marketing any product I designed.  Microchip, was to fax me something
but it didn't arrive (about a month ago).  Anybody know what's going on
here?  No, I'm not imagining things, even though it is late.  I do have
names of people I spoke with and will gladly provide them privatly.

Anyone know for sure why I was told by Philips that Microchip was on their
bad list?
