Caltech (California Institute of Technology) has sued Nokia, LG, Pantech and a number of chipmakers this week, claiming phones made by the companies have components that infringe on their patents.
The university says the mobile phone makers infringe on nine patents relating to camera technology.
Caltech is seeking monetary damages.
Similarly, last year Caltech sued Canon, Nikon and 4 other digital-camera makers, for infringing on six patents relating to pixel sensors in digital cameras.
All of the patents came after research the university was doing for NASA.
The chipmakers named are STMicroelectronics, Seti, Siliconfile Technologies and Toshiba.
None of the companies named have responded to the allegations yet.
