to
receive a copy likewise does
not
require acceptance. However,
nothing other than this License grants you permission
to
propagate
or modify any covered work. These actions infringe copyright
if
you
do
not
accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance
of
this License
to
do
so.
10.
Automatic Licensing
of
Downstream Recipients.
Each
time you convey a covered work, the recipient automatically
receives a license from the original licensors,
to
run, modify and
propagate
that
work, subject
to
this License.
You
are
not
respon-
sible for enforcing compliance by third parties
with
this License.
An
"entity transaction"
is
a transaction transferring control
of
an
organization,
or
substantially all assets
of
one,
or
subdividing
an organization,
or
merging organizations.
If
propagation
of
a
covered
work
results from an
entity
transaction, each
party
to
that
transaction
who
receives a copy
of
the
work
also receives
whatever licenses
to
the
work
the party's predecessor in interest
had
or
could give under the previous paragraph, plus a
right
to
possession
of
the Corresponding Source
of
the
work
from
the
predecessor in interest,
if
the predecessor
has
it
or can
get
it
with
reasonable efforts.
You
may
not
impose any further restrictions
on
the
exercise
of
the
rights
granted
or
affirmed under
this
L.iceme.
For
ex~mple,
yov
may not impose a license
fee,
royalty, or other charge for exercise
of
rights granted
under
this License, and you may
not
initiate
litigation (including
a cross-claim
or
counterclaim
in a lawsuit) al-
leging that any patent
claim
is
infringed by making, using, selling,
offering for
sale,
or
importing
the
Program
or any
portion
of
it.
11.
Patents.
A
"contributor"
is
a
copyright
holder
who
authorizes use under
this License
of
the
Program
or
a
work
on
which
the
Program
is
based.
The
work thus licensed
is
called
the
contributor's "contrib-
utor
version".
A
contributor's
"essential
patent
claims"
are all
patent
claims
owned or controlled
by
the
contributor, whether already acquired
or hereafter acquired,
that
would be infringed by some manner,
permitted by this License,
of
making, using, or
selling
its contrib-
utor
version,
but
do
not
include
claims
that
would be infringed
only
as
a consequence
of
further modification
of
the contributor
version. For purposes
of
this
definition,
"control" includes
the
right
to
grant patent sublicenses in a manner consistent
with
the
requirements
of
this License.
Each
contributor
grants you a
non-exclusive, worldwide, royal-
ty-free
patent
license
under
the
contributor
's essential
patent
claims,
to
make,
use,
sell,
offer for
sale
,
import
and otherwise run,
modify and propagate the contents
of
its contributor version.
In
the
following
three paragraphs, a "patent license"
is
any express
agreement
or
commitment,
however denominated,
not
to
en-
force a patent (such
as
an express permission
to
practice a patent
or covenant
not
to
sue
for patent infringement).
To
"grant"
such
a patent license
to
a party means
to
make such an agreement
or
commitment
not
to
enforce a patent against the party.
If
you convey a covered work,
knowingly
relying
on
a patent li-
cense,
and the
Corresponding
Source
of
the work
is
not
available
for anyone
to
copy, free
of
charge and under
the
terms
of
this Li-
cense,
through
a
publicly available
network
server
or
other
reesdily
accessible means, then you must either
(1)
cause the
Correspond-
ing Source
to
be
so
available,
or
(2)
arrange
to
deprive yourself
of
the benefit
of
the patent license for this particular work,
or
(3)
arrange, in a manner consistent
with
the
requirements
of
this
License,
to
extend the patent license
to
downstream recipients.
"Knowingly
relying"
means you have
actual
knowledge
that,
but for the patent license, your conveying the covered
work
in a
country,
or
your recipient's use
of
the covered
work
in a country,
would infringe one
or
more identifiable patents in
that
country
that
you have reason
to
believe
are
valid.
