The Dentons news is that they are patenting (recent etn update email) some technology they are using in their product. What this technology is I don't know but it's something new... It will also take a while to be approved (years - I am serious about that, I have dealt with them before). I will also be checking if it's a global patent or just UK/EU/US. I am really interested to see what this new technology is and what other companies it will 'shut down' :)
