The White House on Thursday announced new initiatives intended to create more transparency and reduce abusive and deceptive practices in the U.S. patent system—part of the Obama administration’s effort to curb the activity of so-called patent trolls.

The administration also detailed steps it has already taken in this regard and reiterated its call to Congress to pass bipartisan legislation that will further reform the U.S. patent system and reduce abusive litigation brought about by patent trolls, a term used to describe entities that buy up and assert patents to extract payments via settlements or litigation.
