Patent Law is a branch of intellectual property law that grants inventors exclusive rights to their inventions for a limited time, typically 20 years. This legal protection encourages innovation by allowing inventors to profit from their creations without the fear of others copying them. To obtain a patent, an inventor must publicly disclose the details of their invention, demonstrating that it is new, useful, and non-obvious. The process of obtaining a patent involves submitting an application to a government authority, such as the United States Patent and Trademark Office (USPTO). Once granted, the patent holder can prevent others from making, using, or selling the invention without permission, fostering a competitive market and promoting technological advancement.
