If that's your most pressing concern about expanding the business you should probably consider challenging the validity of the patent if it's truly as obvious as it seems.
Challenge it after being sued hopefully with enough cash to defend yourself.
Then we can brainstorm and see if we can innovate.
But, to make the exercise a bit more fun!? Don't read the EFF's summary, go read the patent and try to make sense of it. If you were an e-health company how would you work around that patent?
