Qualcomm files new patent infringement complaints against Apple

Qualcomm files new patent infringement complaints against Apple

Yet this is probably the last time Apple will be using Qualcomm modems since it is now caught up in a lawsuit against the giant.

The three new claims bring the total number of Qualcomm patent complaints to 16, ZDNet reports.

Qualcomm is thus praying for an injunction from the court that would bar Apple from selling the GSM version of 2017 iPhone models; iPhone 8, iPhone 8 Plus and iPhone X because they do not feature the Qualcomm -made modem chip inside.

Cellular Insights notes that the performance gap between Qualcomm and Intel was more pronounced a year ago 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.

At the root of the conflict between the two companies is Qualcomm's broadband processor technology that enables mobile phones to connect with cellular networks.

The new complaints represent the latest development in a long-standing dispute and follows Apple's countersuit on Wednesday against Qualcomm, which alleged that Qualcomm's Snapdragon mobile phone chips infringed on Apple patents. Apple has since that day in time become Intel's largest customer.

According to Qualcomm, Apple uses technologies that Qualcomm first marketed in the 1990s. Apple stopped paying Qualcomm for patent royalties and instructed its manufacturing partners to do the same which has blown over the legal tussle between the two companies.

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. Qualcomm's modem was able to retain better speeds at every step down but one - Qualcomm and Intel matched speeds at -100dBm. Then Qualcomm responded during the summer by taking Apple to court for patent infringement themselves.

In an in-depth look at the conflict between Apple and Qualcomm in October, Bloomberg described the dispute as a "billion-dollar war over an $18 part".
