Answer:
Protecting sovereign boundaries regarding intellectual property has a positive effect on the GDP because by protecting intellectual property through the use of patents and copyrights, other countries and companies cannot make money by simply copying what another has done.
However, the protection of the inventor's rights that patents give are usually limited so that there is time for the original inventor to gain profit from their intellectual property before others are permitted to develop the innovation further later on. After the original inventor dies or the patent expires, such a design can be shared with others to promote efficiency and forward-thinking in the economy as a whole as well as to inspire possible future inventors.
To recap, protecting intellectual property allows for more monopolistic competition between companies and countries, which has a positive effect on the overall GDP as well as provides incentives that are known to promote economic growth.
