Although apple and Qualcomm shake hands on patent licensing, they can't help but become targets of attack.
According to the latest report, patent company (non professional entity) red rock filed a lawsuit in the U.S. West District Court of Texas on Thursday, accusing Qualcomm's 5g products of infringing its RF calibration patent.
The plaintiff's infringement products include smr526, sdr865 and sdx55m. The latter is the snapdragon x55 5g baseband, which is used for a large number of 5g new machines released around 2020. However, the plaintiff specifically mentioned Apple's iPhone 12 series products.
Red rock's U.S. patent code is 7346313, which outlines a system for calibrating the balance of in-phase (I) and quadrature (q) signals in radio transceivers. RR even pointed out that both apple and Qualcomm infringed the 313 patent with clear knowledge of its existence, and they received patent notifications at least three times between 2008 and 2011.
Generally speaking, intellectual property litigation is usually protracted, and we will also pay attention to the follow-up progress of the case.
