From the recent BFM Breakaway 2016 as elaborated by @Afzal Abdul Rahim, here are the usual 3 type of ideas:
1. Authentic: an idea that is usually spawned by an internal problem, pain, experience, need or inefficiency/deficiency.
2. Original: an idea that is derived from no. 1, but witnessed and the solution from a 2nd or 3rd party.
3. Unique: a copy from any 2 of the above but improved to be different, much better, innovative, etc.
1 is the rarest, followed by 2 and 3, most common.
