The World Intellectual Property Organisation (WIPO) has recently launched a new service, WIPO PROOF, which can be used to apply a secure timestamp to a digital file. This timestamp can be used to prove that the digital file existed at a particular date. IP assets are increasingly being generated digitally during the innovation life cycle. In some cases, digital assets cannot be protected through conventional registered IP rights such as patents. In other cases, it is desired to keep digital assets as trade secrets. These situations can cause problems in legal disputes when there is a disagreement about the date that a digital file was created.
