Realizing that defensive disclosure is not the only option for traditional knowledge holders, AAAS has created a handbook that attempts to make intellectual property protection options more understandable and readily available for traditional knowledge holders. Its goal is to help local communities understand and identify potential protection mechanisms already present in current intellectual property rights (IPRs) regimes and the public domain for traditional knowledge. In addition to introducing some basic intellectual property concepts, this handbook contains a series of exercises to help the reader to identify knowledge and classify types of knowledge, as well as cultural and interest-related aspects of that knowledge. Through a series of exercises, it is possible for traditional knowledge holders to identify whether or not intellectual property options in the current regime are relevant and/or appropriate for their knowledge.
