Obama signs bill to speed patent process

Passed in a rare display of congressional bipartisanship, the America Invents Act is the first significant change in patent law since 1952. It has been hailed as a milestone that will spur innovation and create jobs. The bill is meant to ensure that the patent office, facing a backlog of 1.2 million pending patents, has the money to expedite the application process. It now takes an average of three years to get a patent approved. More than 700,000 applications have yet to be reviewed.

“Somewhere in that stack of applications could be the next technological breakthrough, the next miracle drug,’’ Obama said. “We should be making it easier and faster to turn new ideas into jobs.’’

The president signed the bill after touring Thomas Jefferson High School for Science and Technology in Alexandria, Va., where he examined student projects, including a wheelchair that responds to brain waves.

The law aims to streamline the patent process and reduce costly legal battles. It was backed by companies including Google and Apple as well as the US Chamber of Commerce. Small-scale inventors are divided, with some arguing that the law will give the edge to big corporations.

Obama was joined at the signing ceremony by Senate Judiciary Committee chairman Patrick Leahy, a Vermont Democrat, and House Judiciary chairman Lamar Smith, a Texas Republican, the two main sponsors of the legislation.
