Mobile app maker Vringo announced on Thursday that it will acquire a portfolio of more than 500 worldwide patents and patent applications from Nokia, including 109 issued U.S. patents.

"Thirty one of the 124 patent families acquired have been declared essential by Nokia to wireless communications standards," the company said in its press release. Vringo will license the patents and use them for litigation against other companies, The Wall Street Journal said. Earlier this week, Vringo settled part of a patent infringement battle with AOL, for example.

The complete terms of the deal were not disclosed, but Vringo agreed to compensate Nokia an undisclosed amount of cash and will provide revenues earned from the patent portfolio and will provide "certain ongoing rights" to the patents. The patents purchased include one for a method for communication management, another for data and signal transmission and one for radio resource management.

Nokia's patent sale falls in line with several other steps the company has made to revitalize its balance sheet. It recently said it will be laying off 10,000 employees and is selling 90 percent of its stake in Vertu. Nokia sold 4 million Lumia devices during the second quarter, but it still reported a net loss of $1 billion.
