In the digital world of the Internet, IPR conventions, such as trademarks to identify market products and services, copyrights covering the software running websites and apps, and agreements defining usage rights (i.e. licences), allow traded goods to move digitally, their significance has increased appreciably. The extent of intellectual property rights coverage and their enforcement among different members may vary significantly, enforcement action by a rights owner can in many cases involve costly multi-jurisdictional litigation and other procedures before numerous national authorities. As intellectual property has traditionally been regulated, administered and enforced on a territorial basis, the "borderless” nature of the Internet can raise trade costs in both registering and enforcing intellectual property rights in the context of global networks.
