This article discusses how indigenous groups are using intellectual pr
operty rights (IPR) law and how these rights are being expanded. Indig
enous groups and their advocates in the United States, Canada, and oth
er countries are experimenting aggressively with IPR to solve a keenly
felt problem: how to gain control over what outsiders can use of indi
genous culture. The main instruments of intellectual property are ill
suited for this job; however the applications of IPR for tribal groups
are not negligible and are providing some legal protections. Indigeno
us groups and their advocates are also conducting an extensive global
campaign to modify or supplement existing IPR instruments to make them
more useful for protecting traditional culture. In the interim, indig
enous groups are relying on measures at the level of their reservation
s and tribal governments that, in varying degrees, impose some collect
ive control over outsiders' unfettered appropriation of their cultural
information.
