"I'd like to reassure everyone. Red Hat's patent claim is very weak. iMatix first proposed content-based exchanges in the AMQP draft specs two years before Red Hat filed this. Further, the actual design is poor: dynamic routing XML is obvious but slow. There are faster ways to do this - extract the essential routing data from the XML and turn into a topic key or headers. But the quality of the patent is actually irrelevant. What we have seen is that there is a risk that participants in the AMQP process will silently file patents on it. which would be detrimental to all of us, user and open source vendors alike. Even if this particular patent is contested and rejected, there will be others."
