Baltimore – Two years after suing Facebook for patent infringement, Baltimore-based WhoGlue, a small developer of software for membership organizations, has now been acquired by the social networking giant, according to multiple reports.Financial terms of the deal were not disclosed.

Facebook reportedly plans to incorporate the company’s technology, which allows membership organizations to form private social networks.

As part of the deal, WhoGlue founder Jason Hardebeck said he has repurchased some of the company’s trademarks and software, and plans to relaunch the remnants of his company under the name WhoGlue LLC, according to the Baltimore Business Journal.

WhoGlue in late 2009 filed suit against Facebook, claiming the company was violating its patent for methods of managing personal relationship data on the Internet. Hardebeck told The Baltimore Sun that the suit was settled in a “very positive” way.
