Qualcomm fires back at Apple with new batch of patent infringement suits

  • Verizon vs AT&T iPhone X versions tested big advantage for Qualcomm's modem in weak-signal scenarios

There are three new complaints that Qualcomm is throwing at Apple.

Cellular Insights notes that the performance gap between Qualcomm and Intel was more pronounced previous year between -97dBm and -117dBm - suggesting that Apple put a heavier hand into tuning performance to make it seem like both versions performed identically to users.

Cellular Insights, in conjunction with PCMag, tested the performance of the A1865, the Qualcomm unit intended for use with Sprint, US Cellular and Verizon networks, and the A1901, Intel's work found in AT&T and T-Mobile in the United States.

Qualcomm in November sued Apple over an alleged breach of a software agreement between the two companies. Qualcomm's modem chip design was used to set the industry standard for mobile communications, and cellphone makers, including Apple, have paid Qualcomm regular royalties for the rights to use that technology.

According to Qualcomm, Apple uses technologies that Qualcomm first marketed in the 1990s.

It has 1 GB RAM , which is disappointing when compared to the Xiaomi Redmi 5A , which lets you choose between 2 GB and 3 GB RAM . The Xiaomi Redmi Y1 is powered by 1.4GHz octa-core Qualcomm Snapdragon 435 processor and it comes with 3GB of RAM .


All three cases that were filed on Thursday have been filed in the US District Court for the Southern District of California in San Diego. However, Qualcomm still believes that the dispute could be resolved outside the courts.

The complaint continued, "Notably, all of Qualcomm's asserted patents were filed and prosecuted well after the iPhone was introduced".

The patent drama between Qualcomm and Apple is ever-changing it seems. Because the Qualcomm modem chip was much faster over LTE than the one made by Intel, Apple was forced to throttle its speed so that there wouldn't be a huge discrepancy in performance between the CDMA and GSM models.

Qualcomm in July accused Apple of infringing several patents related to helping mobile phones get better battery life. In the meantime, processor rival Broadcom last month launched an unsolicited attempt to acquire Qualcomm.
