The spec for iBeacon is proprietary and the name is trademarked (http://tmsearch.uspto.gov/bin/showfield?f=doc&state=4803:h5eavx.2.1 http://tmsearch.uspto.gov/bin/showfield?f=doc&state=4803:h5e...). IIRC, Apple even went so far as to revoke iBeacon usage from companies that tried to make an Android library (Radius Networks, the creators of this spec, being one of them).
