Hello all.
I'm wondering how does existing XMP-RPC patent
[http://www.google.com/patents/about?id=WFV4AAAAEBAJ&dq=xml-rpc]
effect to usage of Jabber-RPC
[http://xmpp.org/extensions/xep-0009.html]? Does someone has more
information about the topic or the mentioned patent?
Isn't information provided by the XEP series in the public domain?
I mean google would be applying for patients on their own
technology improvements although it might initially have been based
on XMPP standards.
That's *not* Google. Google may be many things, but to the best of my
experience they've never done a submarine patent job.
I am not a patent lawyer.
That said, XEP-0009 (and other XEPs, feel free to find those
yourself) does look as if it might be argued to be covered by this,
by the kinds of idiots that like to register these patents in the
first place.
That said, I'd consider any RPC based system that used an encoding
method wherein the data types were indicated by type labels would
surely count as prior art, since replacing DER or XDR with XML is
hardly an innovative, non-intuitive step.
XDR based RPC - which has all the properties of this patent except
that the nebulous term "mark-up language" cannot be applied - has
been used since at least 1987. That's quite possibly a newbie
compared to some of the DER/BER RPC stuff that's been about for
years, too - SNMP, for instance, seems to have all the features of
this patent excepting "mark-up language", and dates from 1988 -
CMIS/CMIP date from before that and also, I believe, have largely
similar features.
I'd feel pretty confident in suggesting there's significant prior art
involved here.
