The law of patent, trademark law, copyright law and the law relating to industrial designs are the statutory enactments forming part of intellectual property law which have a bearing on the transfer of technology. There is one more branch of intellectual property law which also has a bearing on the transfer of technology and that is the law relating to confidential information or law relating to confidentiality. This law is not a written law; it is judge made law, in the sense that it is developed through cases.
