Since January 2011 Nvidia had a cushy deal with Intel where Chipzilla would pay it $1.5 billion. It was great while it lasted but Intel has almost paid up and Nvidia thought it could get a similar licensing deal from Samsung and Qualcomm.
It unleashed its mighty briefs in September 2014 claiming that Samsung and Qualcomm had breached United States Patent Nos. 6,198,488, 6,992,667, 7,038,685, 7,015,913, 6,697,063, 7,209,140 and 6,690,372.
These patents were allegedly used in now ancient Qualcomm Snapdragon S4, 400, 600 or 800 series of processors, and devices such as the Samsung Galaxy Note 4, Galaxy Note Edge, Galaxy S5, Galaxy Note 3 (LTE), Galaxy S4, and Galaxy S III and the Samsung Note Pro LTE, Galaxy Tab 4, and Galaxy Tab 3 tablet. It should have had Nvidia on a nice little earner.
Then something odd happened. Nvidia only mentioned Samsung in the lawsuit and stopped talking about Qualcomm. In September 2015 judge ruled that Samsung and Qualcomm actually didn’t infringe two of the patents.
It seems then that Nvidia went back to the negotiating table. It appears to have got a few minor agreements from Samsung and Qualcomm, but nothing like the sort of money it got from Intel.
The deal was so minor that Nvidia doesn’t want to talk about it. All the company is saying at this time the agreement covers the licensing of a small number of patents by each company to another.
