Adobe Patents RTMP

I'm not sure about it - but they say they did. In their recent FMS3 white paper on page 8 there's a reference to "the Adobe patented, RTMP over Transmission Control Protocol". I'm not sure if this was common knowledge but as far as I remember there was no known patent in existence around RTMP - but it certainly looks like there is now. A quick Google patent search brough up this result.
While RTMP has not been patented explicitly in this patent, something that sounds even wider reaching has (at least to my limited experience), namely a "Method and system for facilitating communications between an interactive multimedia client and an interactive multimedia communication server".

While I don't know if this particular patent is the one cited in the white paper but it was the only one I could find that appears applicable. It is US patent number 7246356, filed on Jan 29, 2003 (that's not too long after FCS was released and way before FMS2) and issued on Jul 17, 2007.
The inventors list is a who's who of Flash and FMS and includes Slavik Lozben, Pritham Shetty, Jonathan Gay, Stephen Cheng and Bradley Edelman.

I'm not sure what implications (if any) this patent may have for the likes of Red5, Wowza and other RTMP servers but it certainly appears that Adobe wants to protect their intellectual property at least on paper and 'just in case'. [More]
