Ya, I don't understand how that's patented. It must be a very specific patent. A few years ago when I first learned of the woes of TCP over lossy links literally the first thought that popped into my head was "why not code N packets into M>N and recover using Gaussian elimination over GF-2"? Such an idea could have passed for non-obvious maybe 50 years ago but it's a pretty basic idea in the 21st century. To be clear, you can trivially apply any technique here: https://en.wikipedia.org/wiki/Erasure_code https://en.wikipedia.org/wiki/Erasure_code across packets in a channel.
