Limiting debate, or reaching cloture, required 60 votes while the vote on final passage will require a simple majority. Now that cloture has been reached, the Senate will spend a maximum of 30 hours on further debate before the final vote where the bill is expected to pass by a wide margin.

Amendments are allowed during the post-cloture period of debate with unanimous consent. 

The Senate Judiciary Committee began considering several versions of the Patent Reform Act starting in 2005 but ran into opposition and various obstacles along the way. The last time Congress enacted significant patent reform was more than 60 years ago.

The three no votes were Sens. Maria Cantwell (D-WA), Mike Crapo (R-ID) and Jim Risch (R-ID.)
