Swedish telecommunications gear vendor Telefon AB L.M. Ericsson (ERIC) said Friday that as part of a consortium it has won the bid for Canada's Nortel Networks Corp.'s (NRTLQ) remaining patents and patent applications.

The total cash purchase price amounts to $4.5 billion, of which Ericsson's contribution is $340 million, with the rest made up from the other members of the consortium that includes Apple Inc. (AAPL), EMC Corp. (EMC), Microsoft Corp. (MSFT), Research In Motion Ltd. (RIMM) and Sony Corp. (SNE).

The purchased patent portfolio includes around 6,000 patents and patent applications in telecommunications, internet search and social networking, and covers mobile, long term evolution and data networking as well as optical, internet, service provider, semiconductors and other patent portfolios, the company said in a statement.

Google Inc. (GOOG) had originally made a "stalking horse" bid on the patents of $900 million in April and the auction itself was delayed by a week after Nortel said it had seen a "significant level of interest" in the portfolio.

"We believe the consortium is in the best position to utilize the patents in a manner that will be favorable to the industry long term," Kasim Alfalahi, Ericsson's Chief Intellectual Property Officer said.

The deal is expected to close in the third quarter of 2011, following approval by the United States and Canadian Bankruptcy Courts.

Nortel filed for bankruptcy in 2009, and has been selling off assets in bankruptcy court since.

Among other asset sales, Ericsson bought Nortel's CDMA business for $1.1 billion in 2009, Avaya purchased Nortel's enterprise unit in 2009 for $900 million, while Ciena Corp. (CIEN) bought the metro ethernet business in 2010 for $774 million.

SEB Enskilda is acting as financial advisor to Ericsson in the transaction.

Shares in Ericsson closed Thursday at SEK91.20.
