What is a Public-Use Bar? A Comprehensive Legal Overview
Definition & Meaning
A public-use bar is a legal concept that prevents an inventor from obtaining a patent for an invention if it has been publicly used or sold in the United States more than one year before the patent application is filed. For instance, if a patented device, such as a computer, is used publicly even once within that timeframe, the inventor cannot secure a patent, regardless of whether they made a profit. However, if the invention is tested or demonstrated to a limited group of people for experimental purposes, this does not count as public use and will not affect the ability to patent the invention after the critical date.

Key legal elements
Real-world examples
Here are a couple of examples of abatement:
Example 1: An inventor publicly demonstrates a new type of software at a technology conference in January 2022. If they file a patent application in March 2023, they may be barred from obtaining a patent due to this public demonstration.
Example 2: An inventor tests their new gadget in a private workshop with a small group of colleagues. This demonstration does not count as public use, allowing them to file for a patent later without issue. (hypothetical example)
