Troubled Internet company, Yahoo!, has warned social media outfit Facebook to license all its patented technologies so as to avoid potential legal consequences in the future.

Apparently, Yahoo! Inc. believes that Facebook is using a number of its proprietary intellectual properties to build the massive social media platform that enjoys well over 800 million active users.

"We must insist that Facebook either enter into a licensing agreement or we will be compelled to move forward unilaterally to protect our rights," the California based web behemoth stated in an email statement reports  Business Week.

While sceptics claim that the biggest Internet portal in the US has been in search of an easy way out of the financial debacle it is currently in, Yahoo! defended its stand by saying that other companies should be committed to licence all those technologies which it invented or acquired with lots of cashes and/or efforts.

"Yahoo has a responsibility to its shareholders, employees and other stakeholders to protect its intellectual property," added the company.

However, Yahoo! did not reveal the names of other companies who are infringing on its patents and neither did it disclose what technologies were covered by these patents.
