Found a good article over on the EFF site where they have sent an open letter to Congress requesting investigation into patent trolls.

I do remember last year that the Congressional Research Service did start an investigation into patent trolling but never heard the outcome.

In an open letter to the House Committee on the Judiciary, the coalition—including investor Mark Cuban and Reddit co-founder Alexis Ohanian—explains how patent trolls are chilling innovation, which in turn stifles job growth in the expanding tech sector. Researchers estimate that the U.S. economy took at least a $29 billion hit in 2011 due to patent trolls, which make no products but instead assert patents as their sole business model.
