US Patent # 09883064 - Peer to Peer Print

I am listed as an author on US Patent # 09883064 for peer to peer file sharing which we developed at Flycode where I was CTO.

There were two key innovations - the first was to use file hashing so that files could be found even when named differently on different peers.

The other key innovation - which wasn't covered very well in the patent - was a technique for swarming based on splitting the file up and accessing parts from different servers - this is essentially wat BitTorrent does now.

The patent was aquired when Flycode went under, and I'm not sure who owns it now.
