patent length

Patent length refers to the duration during which a patent holder has exclusive rights to their invention. Typically, a patent lasts 20 years from the filing date, granting the inventor control over the use, production, and sale of their invention. This period allows inventors to recoup their investment and encourage innovation. After the patent expires, others can use the invention without permission, fostering competition and the availability of the technology. Different types of patents, such as design or utility patents, may have varied terms or conditions, but the 20-year rule is commonly applied to utility patents.
