Apple is drawing a legal challenge from Boston University.  The university is suing to stop sales of Apple's iPhone 5, iPad and MacBook Air. 

The school says they're using technology patented by one of its professors in 1997.  B-U wants a cut of all profits from the devices, plus interest, which analysts guess could be up to 75-million dollars.

The school has also sued Amazon and Samsung over similar issues in the past year.
