Although the act includes a number of small changes, the meat of it is considered the biggest shakeup at the USPTO since 1952. Formally known as H.R. 1249, the act was penned by Sen. Patrick Leahy (D-VT) and Rep. Lamar Smith (R-TX), the duo who introduced the Stop Online Piracy Act (SOPA) and Protect IP Act (PIPA). For product designers and makers and DIYers the proverbial monkey wrench is being thrown into the mechanism for filing a patent — and the timing with which you do so. Today, if you file a patent, someone can come along and tell you they had that idea first, and with much documentation and legal wrangling, deny you the right to apply that invention. Tomorrow, nobody will care who came up with the idea first — only who filed it.
