Boston University Sues Apple Over Gallium Nitride Thin Film Patent
The suit, filed in U.S. District Court for Massachusetts, is for a patent awarded to a BU professor for which the university owns the rights.
U.S. Patent 5,686,738, titled "Highly Insulating Monocrystalline Gallium Nitride Thin Film" is related to a particular manufacturing process for LEDs and other semiconductor devices.
The lawsuit does not specify what inside Apple's products is alleged to be infringing, just noting Apple products in general. Boston University has sued a number of other companies over the same patent in recent months, including Samsung [PDF].
