Non-patented inventions are typically those that either did not meet the criteria for patentability or were never formally submitted for patent protection. Examples include ideas that are considered abstract concepts, natural phenomena, or inventions that have been publicly disclosed without a patent application. Additionally, some inventors choose not to patent their creations to keep them as trade secrets or because they believe the patent process is too costly or time-consuming. Open-source technologies and traditional knowledge are also often non-patented.
