Patent licensing firm targets Apple's 3G cellular technology in new lawsuit

Non-practicing entity TOT Power Control, the licensing arm of Top Optimized Technologies, this week filed suit against Apple for infringing a pair of wireless communications technology patents covering baseband modem power output and its relation to call quality.

iPhone 12 Pro


Lodged with the U.S. District Court for the District of Delaware on Tuesday, TOT Power Control's complaint alleges Apple products like iPhone, Apple Watch and iPad contain wireless baseband components, including those manufactured by Qualcomm and Intel, that infringe on owned intellectual property.

Specifically, U.S. Patent Nos. 7,532,865 and 7,496,376, both from 2009 and titled "Outer Loop Power Control Method and Device for Wireless Communications Systems," are asserted in the case.

As described in the complaint, power control is utilized in 3G wireless communications protocols to avoid interference between user equipment codes in uplink and downlink signals. Power control for ongoing transmissions, like phone calls, is reliant on a closed loop system that adjusts transmission power (inner loop) based on on a signal-to-interference ratio target (outer loop).

While standards like 3GPP UMTS offer specifications for inner loop power control, outer loop algorithms, which adjust the signal-to-interference ratio target to account for changing radio conditions, are not well defined, the complaint says. TOT's patented solutions manage signal-to-interference ratio target values "so that power, and consequently wireless channel capacity, is not wasted and call quality is maintained." Each IP focuses on reducing interference by applying specialized code to the outer loop process.

Apple's iPhone, Apple Watch and iPad are named in the complaint.

TOT has sued a number of major wireless carriers over similar claims in the past including Vodafone Spain, Verizon, AT&T and T-Mobile. Huawei was also named as an infringing party in TOT's suit against Vodafone Spain after the telco backed out of a 2012 licensing agreement to implement 3G technology developed by the Chinese company.

TOT in its suit against Apple seeks damages, royalties and court fees.

    Apple is seldom an innovator. It is amazing Apple being sued so often for patent infringement. Probably because Apple has so much money. Apple just designs a device using components invented by its suppliers. Engineers created software to integrate these components. This is all Apple does. The great success is due to the greatest integrator Steve Jobs who designed Apple products to suit the users.

    Weird how they're going after this at the tail end of 3G. At least AT&T appears to be discontinuing 3G about 6 months from now.

    That was my reaction too.  They seem to be a bit late to the party.

    I think all the US carriers are. Time for a motion to dismiss

    LOL, the time to pursue this was when Apple introduced the iPhone 3G, one would think.

    This is a pure, naked attempt at a cash grab as 3G in smartphones rides off into the sunset.
