Twitter following Facebook

Twitter Inc (NYSE:TWTR) in a statement said that the, deal with IBM will give the company “greater intellectual property protection and gives us freedom of action to innovate.”

A cross-licensing agreement with IBM would protect Twitter against similar accusations in the future. Twitter it seems like is following a strategy similar to its bitter rival Facebook, which also faced similar accusations before its IPO, in 2012.

Before filing its IPO, the micro-blogging site had only nine patents and 95 pending applications.

In a joint with IBM on Friday, Twitter’s legal director, Ben Lee said “This acquisition of patents from IBM and licensing agreement provide us with greater intellectual property protection and give us freedom of action to innovate on behalf of all those who use our service.”
