- H syndrome - potato farmer invents Internet in 1998
- I syndrome - startup company gets 1996 patent on communicating using
    computers
- J syndrome - Large companies stockpile as a deterrent
- K syndrome - Really interesting novel and powerful idea protects the
    inventor's deployment .. but does it help the community?
- X syndrome - Really interesting novel powerful valid patent comes out
    of left field non-participant?
X has not happened in my experience
