Qualcomm has lowered the number of legal tussles it is involved in by one after it agreed to pay BlackBerry almost $1 billion to resolve a row.
In a short statement, BlackBerry said the payment of $940 million relates to royalty overpayments it made to the chipset maker.
In April of last year, the two companies sought to resolve a disagreement over whether Qualcomm's decision to cap royalties on certain payments also applied to a licence agreement with BlackBerry.
BlackBerry was initially awarded $814.9 million last month, but the final figure also includes "interest and reasonable attorneys' fees".
Qualcomm has been involved in a spate of legal action with Apple, accusing the iPhone maker of underplaying the value of its chipsets and breaking agreements.
Qualcomm has warned it could take as much as a $1.3 billion hit on its revenues when it next reports its quarterly figures. Sales will now sit between $4.8 billion and $5.6 billion, down from its previous prediction of $5.3 billion and $6.1 billion.
Qualcomm is also suing the four manufacturers of Apple's iPhones, claiming the companies are in breach of contract.
While Qualcomm and Apple are facing off, the iPhone maker settled a patent row with Nokia last week.
A multi-year patent agreement between the two companies will involve Nokia supplying Apple with network infrastructure and services in future.
