Apple is embroiled in a legal battle concerning the utilization of 4G patents in both the UK and the US, potentially facing an additional patent fee of roughly RMB 0.86 per iPhone. While this amount may initially seem negligible, Apple fears that this decision could catalyze a global chain reaction, drastically escalating its patent expenses. Patent licensing is supposed to adhere to the Fair, Reasonable, and Non-Discriminatory (FRAND) principles. Nevertheless, Optis Wireless Technology, which holds a limited number of 4G patents, is demanding exorbitant licensing fees, prompting Apple to accuse them of "patent troll" tactics. The UK Supreme Court has ruled that the patent fee payable by Apple will soar from 2 cents to 14 cents per iPhone and asserts the right to establish a uniform global rate. Apple has decided to appeal this decision, with the final verdict anticipated next year. Apple underscores that this lawsuit transcends its own interests, encompassing the rights and interests of numerous small and medium-sized enterprises, aiming to shield them from the heavy burden of high patent fees due to limited legal resources.
