This is an attempt to both shield its large domestic market and to promote exports of biological resource based inventions to foreign markets. The objectives of this legislation include ensuring the sustainable use of biological resources, benefit-sharing and the protection of traditional knowledge. Information in the public domain is often considered in negative terms, as whatever is left over after various tests of legal protection have been 159 applied. This common understanding of the public domain ignores some critical distinctions. On the other hand, the public domain can be thought of in 164 positive terms as a valuable resource. Information in the public domain serves as the foundation for the creation of new knowledge, and as a rich source of content for 165 education. The Government of India, on the other hand, has chosen to restrict information it is documenting on Ayurveda.

The modern concept of property rights belonging to one or more identifiable individuals may be poorly suited to capture the shared development of ideas within an indigenous community. Some national sui generis regimes provide special rules for collective ownership of traditional knowledge. This can be accomplished through individual ownership 168 Some sui generis regimes may still provide some method for compensation.
