I have discovered a bi-level DC-nulled modulation that has better efficiency than the
formerly patented IBM 8B10B, which has only 80%. Namely 90% exactly. And doesn't have excessive requirements on the codec. Maximum run length of identical bits is 10 bits.

That means 1Gbps optical Ethernet could be upgraded to 1.125Gbps probably without a change in the PHY or Ronja Manchester 10Mbps could be upgraded to 18Mbps without a change in the PHY. The same for all the other numerous technologies that use 8B10B,
see the Wikipedia article on 8B10B.

Does anything like this already exist? If not, I could try to make a contract with someonethat he can patent it, sell the patent to proprietary designs only, give irrevocable rights to all open source designs, and pay a fulltime salary to me for the rest of my life. Then I could go developing Ronja :)

Anyone interested?

Otherwise I can write an implementation and publish it to constitute a prior art which makes sure it's unpatentable ;-)
