Re: [Ekiga-devel-list] [info] Re: Ekiga INVITE requests are rejected by OpenIMS P-CSCF

Dear Thomas,

Both Ekiga and the Open IMS Core implement more or less the SIP RFC 3261
as well as other specifications. I think that you should be aware that
any such standards might cover IPRs. e.g. RFC3261:

This are pretty standard claims and in one of them for example, company
X stated:

"To the extent that the technology discussed in the above referenced
IETF document(s) becomes an IETF Standard, and to the extent claims of
X's patents are required to implement the IETF Standard, X agrees that,
upon written request, X will offer, on a nondiscriminatory basis,
non-exclusive licenses on fair and reasonable terms under such patent
claims to implement that IETF Standard. X's willingness to grant such
licenses is conditioned upon the prospective licensee granting a
reciprocal license to X under any patents that the prospective licensee
has to any technology required to implement that IETF Standard."

This statements are made while the specifications are in a draft format,
so you can not talk about prior art. The words are "fair and reasonable"
and not "free for commercial usage". So from how I see it, both of our
project could be infringing patents.

Then there are more standards that we implement coming from 3GPP, ETSI,
TISPAN, CableLabs, ITU, etc.

We chose to warn the users about it, you didn't and now you accuse us of
being untrue and of hiding our real intentions?...

You stated 2 things:
> 1. the disclaimer is unneccesary cause already covered by GPL's
warranty and liability exclude for products without license fee.

Then please feel free to ignore it. In any case, it was just a warning.
Does the "Smoking kills" sign on any cigarette package mean that you are
forbidden to smoke? Then if not, is it unnecessary?

> 2. the disclaimer contains Your expressed forbid of commercial and
production use colliding GPL's expressed intend and ruling for/of
commercial use.
>for me, 2. remains applicable.

Of course, you can believe whatever you want. We think that the text is
clear enough. Contrary to your claims, there are no words like
"restrict" or "forbid" in there.

This whole discussion doesn't make any sense especially as it started
from a some bug-reports from a user. I think that it would be more
important to actually investigate those issues and try to fix them then
to have pointless discussions about the patenting system.
