Apple iPhone 12 series and Qualcomm accused of infringing 5G patents
Although Apple and Qualcomm shook hands-on patent licensing, they did not expect them to become targets of patent infringement lawsuits.
The latest report pointed out that the patent licensing company Red Rock filed a lawsuit in the Western District of Texas on Thursday, accusing Qualcomm’s 5G products of infringing on its radio frequency calibration patents.
The infringing products that the plaintiff sued include SMR526, SDR865, and SDX55M. The latter is the Snapdragon X55 5G baseband, which is used in a large number of new 5G phones released around 2020. The plaintiff specifically mentioned Apple’s iPhone 12 series.
Red Rock holds the U.S. patent number 7,346,313, which outlines a system for calibrating the balance of in-phase (I) and quadrature (Q) signals in a radio transceiver. Red Rock pointed out that Qualcomm and Apple both infringed on the existence of the 313 patent. They received patent notifications at least three times between 2008 and 2011.
The plaintiff requested the court to hold a jury trial and listed a long list of legal remedies, including preventing Apple and Qualcomm from infringing on the 313 patent, compensation, and payment of patent fees.
