barge, I just saw an episode of
"Sharks" were a gentleman proposed (and is in discussions with black and decker) to use the proximity features of a smart phone to unlock a door. Or, send a key to a friend so they can get in, revoke the keys as needed, put time limits on keys and so on.
Unique keys, share-able, revocable, expirable, all based on smartphone proximity (and yes, one can still use their normal key).
And, a couple of sharks did bite for 500k to fund securing the patents.
Wave seems to patent rarely, it costs money, takes time (money), and that money goes into bonuses, not securing inventions. Most of Waves patents do not come from Wave, they come from people or things Wave has bought.
The priority in bonuses, not patent protection.
The gentlemen was explicit in expanding the reach well beyond hard-ware from door locks .... wouldn't the ultimate irony be Wave getting sued for infringement on such matters.
The bonuses are obviously well spent money :)
The above content is my opinion.
