From the Introduction:
The size of the Indian arts and crafts market and extent of misrepresentation are unknown because existing estimates are outdated, limited in scope, or anecdotal. Also, there are no national data sources containing the information necessary to make reliable estimates. For example, the most often cited national estimates about the size of the market and the extent of misrepresentation come from a 1985 Department of Commerce study. GAO found that not only is this study outdated, but the estimates included in the study are unreliable because they were based on anecdotal information and not systematically collected data. No national database specifically tracks Indian arts and crafts sales or misrepresentation, and GAO found that no other national databases contain information specific or comprehensive enough to be used for developing reliable estimates.
U.S. federal and state laws protecting intellectual property do not explicitly include Indian traditional knowledge and cultural expressions—such as ceremonial dances or processes for weaving baskets—and therefore provide little legal protection for them. Some international frameworks offer protection for traditional knowledge and cultural expressions, but the federal government has not yet undertaken steps to implement these frameworks in the United States. Other countries, like Panama and New Zealand, have taken actions—which offer options for consideration—to protect the intellectual property of indigenous groups.
