Although Apple and Qualcomm shake hands with each other in patent licensing, they couldn’t help being attacked together.
According to the latest report, the patent company (non-professional entity) Red Rock filed a lawsuit in the Western District of Texas this Thursday, accusing Qualcomm’s 5G products of infringing on its RF calibration patent.
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. However, the plaintiff specifically mentioned Apple’s iPhone 12 series products.
Red Rock holds a US patent code of 7346313, which outlines a system for calibrating the balance of in-phase (I) and quadrature (Q) signals in a radio transceiver.
RR even pointed out that both Apple and Qualcomm infringed on the existence of the 313 patent, and 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.
Generally speaking, intellectual property lawsuits are usually protracted, and we will also pay attention to the follow-up progress of the case.
