Coreophotonics established the dual camera technology last year at MWC in Barcelona. It displayed how images from both sensors could be combined for a more detailed picture, including an optical zoom up to 5x.
In the complaint, they stated that they received “many encouraging reports and positive feedback” from Apple, but couldn’t reach a patent agreement. Apple allegedly knew about the patents, but their “lead negotiator” said it would take years and millions of dollars before reaching an agreement, a spokesman of Coreophotonics noted.
Back in 2015, Apple acquired LinX Imaging, another Israeli company that specializes in multi-aperture camera equipment for mobile devices. Apple most likely used their technologies in its three dual-cam devices.
