If technology in this document is included in a standard adopted by
IETF and any claims of any Cisco patents are necessary for practicing
the standard, any party will have the right to use any such patent
claims under reasonable, non-discriminatory terms, with reciprocity,
to implement and fully comply with the standard.
The reasonable non-discriminatory terms are:
If this standard is adopted, Cisco will not assert any patents owned
or controlled by Cisco against any party for making, using, selling,
importing or offering for sale a product that implements the standard,
provided, however that Cisco retains the right to assert its patents
(including the right to claim past royalties) against any party that
asserts a patent it owns or controls (either directly or indirectly)
against Cisco or any of Cisco's affiliates or successors in title or
against any products of Cisco or any products of any of Cisco's
affiliates either alone or in combination with other products; and
Cisco retains the right to assert its patents against any product or
portion thereof that is not necessary for compliance with the standard.
Royalty-bearing licenses will be available to anyone who prefers that
option.
Note that if:
- Company A has a patent on nanosecond gate opening
- Company A has issued the claim above, in conjunction with an IETF
standard
- Company B has a patent on the application of slow-drying oil paint
- Company A paints their house with such an oil paint
- Company B asserts their patent on slow-drying oil paint against
company A
then company B will automatically be the target for an assertion of the
nanosecond patent against all its uses of that patent, past, present and
future, within or outside the scope of the relevant IETF standard.
It's a blanket license for use of the technology by any company that
doesn't hold a patent, but it's definitely not a "no strings attached"
policy.
(that said, it is a LOT better than a "we know something, but we're not
telling" policy....)
