It's too bad most on this forum failed reading... Patents are given when 1. the idea or concept is new or 2. has provided new or improved enhancements to existing patents. Since Apple's exploration in Wireless charging began in 2010 with the idea of enhancing a current design, this is the reason they filed the patent.
In any case, Apple, just like any other company has the right to file for patent protection. Just because they are the biggest fish doesn't mean they should slow down or stop working for others to catch up.
If Apple was not around, we would all still have 3.5" floppy drives in our beige box computer because companies like HP, IBM and Acer just want to sell cheap boxes without innovating or just plain updating.
Also, it is quite apparent no one else here holds a patent or has something worth patenting. On the other hand, I hold a couple patents, so protection of my I.P.s are important to me and my company.
