From the patent:

For example, an infrared emitter can be located in areas where picture or video capture is prohibited, and the emitter can generate infrared signals with encoded data that includes commands to disable the recording functions of devices. An electronic device can then receive the infrared signals, decode the data and temporarily disable the device’s recording function based on the command.

In other words, a jammer to prevent picture taking or video recording. I can’t imagine that this invention will ever find its way into a product. If it does, what’s to prevent someone from placing a nuisance jammer in a concert venue, or police from regularly carrying one to prevent unauthorized filming of an arrest?
