OASIS - The
Organization for the Advancement
of Structured Information Standards is a global consortium that
drives the development, convergence and adoption of e-business and
web service standards. Like many bodies producing open standards,
OASIS has a patent disclosure policy requiring participants to
disclose intent to apply for software patents for technologies under
consideration in the standard. However, this policy does not fully
protect the public from potential exploitation of the open process
for the preemptive development of a "standard" which confers a
monopoly license position. See
