And they're filing a patent?

So let me get this straight. Mr Band holds a venue and pays to install Apple's patented film-blocking technology. Then, all of the loyal Apple customers who paid good money for their phones get a feature disabled at the concert. Meanwhile, Joe who bought a cheap Samsung phone can go on recording the event because his phone doesn't have some crappy Apple-patented technology in it.

Or is the idea that when I go to a big name concert, they'll confiscate all the phones that aren't made by Apple?

Either way, the idea, if reported by Fox correctly, is stupid and does not make any sense.
