Hot on the heels of Apple countersuing Qualcomm for infringing on at least eight of its patents, Qualcomm has filed a new patent suit against the Cupertino company for infringing on five of its patents. The patents relate to RF transceivers, device power management, image enhancement using depth-bata, and power efficiency in mobile CPUs.
The lawsuit covers a broad number of Apple devices including the iPhone 7, iPhone 8 and the iPhone X. Qualcomm says that the iPhone 7 uses RF technology that infringes on its patent related to amplification and aggregation, while the iPhone 8 and iPhone X use amplifiers with a design that infringes its patent. Two other patents infringed by Apple related to its A10 chip used on the iPhone 7 and iPhone 7 Plus. The patents pertain to reducing the power consumption of the chip by turning off its certain parts, with the other one related to the SRAM unit logic.
In its suit, Qualcomm says that the iPhone 7 Plus, iPhone 8 Plus and the iPhone X infringe on its “Depth aware enhancement for stereo video” patent. The patent pertains to how phones with a dual-camera setup can improve the overall image and video quality by using the depth data captured from the secondary camera module.
Qualcomm wants a trial and is seeking an injunction against the infringing devices. Like Apple, it is also seeking unspecified damages and fees.
The legal battle between Apple and Qualcomm started in January when the Cupertino company sued the chip maker in a $1 billion lawsuit. Qualcomm first fired back with some harsh statements before it ultimately countersued Apple. Since then, the battle between the two has only worsened, with Qualcomm being the subject of investigations from many regulatory bodies for its unfair business practices.[Via AppleInsider]
