The ever-evolving nature of technology can pose a concern for inventors who have invested time and resources in securing a patent. You might worry that your invention's market dominance will fade as newer, more advanced solutions emerge. While patent obsolescence is a possibility, it does not necessarily negate the value of your intellectual property.

While, a patent itself doesn't necessarily become obsolete, but its usefulness as a tool to protect an invention certainly can. Advancements can render a patented invention obsolete. For instance, a new technology might perform the same function but more efficiently or cheaply. In this case, the original patent might not be valuable commercially, any more. A patent becoming obsolete signifies that it no longer offers the patentee a significant advantage in the market. It might be due to expiry, new inventions, or changes in what people need.
