Is there any difference between "induction" and "resonant" wireless energy transfer?
In my opinion, for the last thirty years, nearly all magnetic induction energy transfer systems place a capacitor to put the secondary coil in resonance. This achieves better power transfer efficiency and everybody knows this. We have been doing this in the medical device industry for [at least] the last two decades. This is just obvious.

Witricity and others have invented this term magnetic resonance to make it sound like they are doing something nobody else has. Don't believe them.

You also hear A4WP using this term to differentiate themselves from Qi. The fact is that Qi standard allows the designer to use either resonant circuits or not. So plenty of Qi systems will use what Witricity and others call "magnetic resonance" to provide more efficiency transfer. Some will opt for a cheaper design that gives shorter range. 

In conclusion, Witricity didn't invent anything. Using resonant circuits in magnetic induction is well known and is used all the time.
