This study provides a theoretical analysis on dynamics of an endogenous growth model under a finiteness of a patent length. In a growth model in continuous time with finitely-lived patents, the law of motions is expressed as a differential-difference equation system, which includes both advance and delay differential equations. We investigate the differential-difference equation system derived from the model, and clarify the impact of a finiteness of patent on the local stability. Our analysis shows that the balanced growth path is locally stable even if a patent length is finite.
