Apple may have just hit Samsung where it hurts as the two companies continue their ongoing legal battles over patents. Apple, said to be the largest buyer of Samsung components, will not use Samsung to build its next-generation A6 processor, Reuters reports. Instead, Taiwan-based TSMC has reportedly been contracted to build the chip, which is expected to power Apple’s future iPhone and iPad devices. TSMC, the world’s largest contract microchip manufacturer, is said to have already begun test production of Apple’s A6 processor. Samsung currently builds the A5 processor used in Apple’s popular iPad 2 tablet and it owns numerous patents surrounding the chip’s design, including a patent that covers the processor’s the system design and memory packaging. The A5 chip is also expected to be included in Apple’s iPhone 5, which is expected to launch later this year.¬†Should TSMC in fact be manufacturing Apple’s next-generation mobile CPU, it will likely feature a significant redesign in order to avoid potential patent complaints from Samsung.
