ALEXANDRIA, VA - SEPTEMBER 16: U.S. President Barack Obama talks with student Alexandria Sutton, 16, about her project while visiting a classroom at Thomas Jefferson High School for Science and Technology September 16, 2011 in Alexandria, Virginia. Later in the morning Obama signed the America Invents Act, which reforms patent law so to give a patent to the first applicant rather than the first inventor and allows the woefully underfunded U.S. Patent and Trade Office to set and potentially keep its own fees.
