American Invents Act
A 2011 US law that changed the patent system from 'first to invent' to 'first to file'. This change incentivizes companies to file patents as early as possible, which inadvertently exposes the invention to 'patent hacking' by competitors.

Summary
The Leahy–Smith America Invents Act (AIA) is a landmark United States federal statute enacted on September 16, 2011, by President Barack Obama. It represents the most significant overhaul of the U.S. patent system since 1952, fundamentally shifting it from a "first to invent" to a "first inventor to file" system. Key provisions of the AIA, which also eliminated interference proceedings and established post-grant opposition, became effective in September 2012 and March 2013. This legislation has broad implications across industries, notably in pharmaceuticals, where it is identified as a factor contributing to strategic challenges like "patent hacking," particularly impacting the development and pricing of drugs such as GLP-1s.

On September 16, 2011, the Leahy-Smith America Invents Act (AIA) became law and significantly changed the U.S. patent system. The AIA not only changes the patentability standards for patent applicants, but it also changes the role of the public in the patenting process which previously was very limited. Below is a brief summary of the changes implemented by the AIA. # First-to-File Patent System [...] All patent applications that claim any subject matter having an effective filing date on or after March 16, 2013 are subject to the new “first-to-file” provisions apply which give priority to the first applicant and not the first inventor. For patent applications that claim only subject matter having an effective filing date before March 16, 2013, the prior “first-to-invent” provisions apply giving priority to the first inventor.

{ Banner Image } # America Invents Act, Ten Years After Enactment PDF Share Icon The Leahy-Smith “America Invents Act” (hereinafter, “AIA”) was signed into law ten years ago, on September 16, 2011. We have learned extensively from the enactment and this article is part of a series of lessons learned. [...] Ten years ago, the US patent laws were long overdue for a realignment to conform to modern standards and International trends. For perspective, the 1952 Act was enacted only a few years after the transistor was invented (1947). In 1954 (and just in time for Christmas), the first transistor pocket radio with four transistors went on sale for $50 (in 1952 dollars). “Smart” phones, even way back in 2011, already had billions of transistors. Furthermore, new tools for programming computers, [...] The AIA made a number of changes to US patent law that harmonized it with the laws of other nations, such as changing the US law from “first to invent” to “first inventor to file” and providing an additional way to challenge an issued patent, and many more.

Provisional applications are patent applications filed in the US Patent and Trademark Office, but, unlike non-provisional (regular) patent applications, they are not examined. However, they are granted a priority date that corresponds to the date they are filed for the invention they describe, and their filing dates can be claimed as the “effective” filing date for a later, regular patent [...] (#_ftnref1) Lincoln was a patentee/genius for a device to lift boats over shoals – US 6469 issued May 22, 1849 (#_ftnref2) The concept of an “inventor” was characterized by one court as “one of the muddiest concepts in the murky metaphysics of patent law.” (Mueller Brass Co. v Reading Industries, Inc., 352 F Supp. 1357, 1372 (E.
