Having visited a workshop on "Ethernet and TCP/IP in Industrial Automation" a simple question popped up during questionaire time:
Does anybody know whether Real Time Innovations has any patents on their NDDS realtime publisher-subscriber system? Are there any patents on their protocol?
I'm asking because the guy from RTI could not answer these questions -- he told the audience that he did not know whether there are patents or no patents on NDDS and the RTPS protocol. Well, that's probably one of the few university spin-offs in the US with a business model not protected by own patents...
Funny was part of the presentation where the guy from RTI talked about RTPS becoming an IETF RFC. After someone asked for details he admitted, that there are several kinds of RFC classes, so RTPS is intended to become an "informationional RFC"--he probably meant a FYI RFC (for your information RFC)...
Ahhh, and then the audience had fun watching PROFInet and iDA eyeing each other carefully and outdoing each other in terms of access latencies around the milliseconds border. And we had even
more fun several times hearing how "company x" grants "initiative y" use of their patented technology. So what happens if someone is not a member of y but does use the software provided by y? So let's see whether the sky will fall and all the automation beasts will overcome us...
Still hoping and waiting for the FAF -- the Free Automation Foundation,
Harald
