I just glanced at the first of the patents that Kodak acquired from Wang and 
is now trying to use against Sun/Java:


Or, if you prefer,


It strikes me that the language of the patent just describes object-oriented 
RPC, such as Java RMI, DCOM, CORBA, or SOAP.  The patent is from 1993, and 
CORBA predates that by a couple of years, so I don't think that Sun will 
have trouble finding prior art, if I've read the patent correctly.  I 
haven't glanced at the other two patents yet (perhaps they will be trickier).

Kodak tried for a couple of years to squeeze money from Sun privately over 
these before the thing ended up in court.  I guess that between hiring Tim 
Bray and deciding to fight these patents openly, Sun is putting its 
Microsoft blood money to good use.

All the best,
