Every once in a while we check out various IP databases around the world to see if we could find any Apple activity. Well, Bingo, we found three all new smart pen patents from Apple that are chock full of great ideas. In between Apple's US patent filings published in May and December, Apple's engineers were filing new patents in Europe that were published just two months ago. These have not been published in the US yet and so they're new to us. And boy does Apple go deeply into the rabbit hole or what. Apple has a ton of new ideas on how to advance the smart pen. Yet the one twist that I thought was intriguing is that Apple appears to be seriously thinking of turning smart pen tips into an accessory business. Do you want your pen to be a brush? No problem, here is a new pen tip for that: Ka-Ching. Do you want your pen to double as a bar code reader? No Problem, here is a tip for that: Ka-Ching. And there are a lot of "Ka-Chingy" ideas in these three new patents to go around. Check it out.
