Gentlemen,

I believe we may be over-simplifying this issue a bit.

X-Windows has been around quite awhile and it either never worked well or never caught on

Last I checked, most UNIX workstations still run some type of GUI that runs on top of X (Motif, e.g.). Also, the cursory investigation that I've done seems to indicate that most GUI's running on Linux boxes are based on X, so ICA clients running in these environments have to deal with the X protocol in some form or another.

I think what may be confusing the issue is that folks may be thinking of X-windows as a protocol for sending screen information between computers. I don't believe that's how the GraphOn product is designed. It can also be used in instances where the X client and servers exist on the same machine.

My reading of their initial press release was that the patent covered a method for dynamically translating Windows API calls into their X-windows equivalent. In other words, the Windows application executes a function to say, open a new window and the GraphOn software passes that call to the X client and translates it into the equivalent X-windows API call.

If that reading of the patent was right, Citrix would only have a problem if they perform a similar dynamic API call translation in the ICA client, and even then it wouldn't have any affect on their non X-windows clients.

DISCLAIMER. I am not a patent attorney nor have I ever played one on TV. Just a software engineer whose worked on plenty of UNIX workstations in my days.
