Prior-User Right is a regulation that grants the initial inventor the right to continue using their invention, even if someone else obtains a patent for it at a later time. This provision serves to safeguard the original inventor in countries where patents are awarded to the first individual to apply for them. Essentially, it asserts the principle of “I created this first, therefore I should be entitled to its continued use.”
The prior-user right is a legal protection that allows the original inventor of a product or process to continue using it, even if someone else later patents it. This right is particularly important in countries that follow a first-to-file system. For instance, let’s consider the scenario where John invents a new engine for cars and starts using it in his vehicles. Later, Tom invents a similar engine and obtains a patent for it. Despite Tom’s patent, John can still use his own engine due to the prior-user right. This example demonstrates how the prior-user right functions in practice. It ensures that John can continue using his invention, as he was the first to invent and use it, safeguarding his interests and preventing unfair consequences from the patent system.
