Twitter has bought 900 patents and signed a cross-licensing agreement with IBM, bulking up on its intellectual property portfolio.
The deal was signed up in December, but the two companies
announced it on Friday.
Financial terms were not disclosed.
The agreement comes after Big Blue accused Twitter in November
of infringing three of its patents.
Facebook had faced similar claims before its own 2012 IPO and
has also acquired intellectual property from Microsoft and
"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," Ben Lee, Twitter's legal director, said
in a joint statement with IBM on Friday.
