You don't understand the filing. All three are emulators. Hercules differs only in that it doesn't cache the results of its interpretation for possible future use. Flex-ES and PSI work in remarkably similar ways, both companies actually using the expression "just in time" or JIT. It's entirely possible that this similarity is related to a non-disclosure PSI had on FSI's technology back in 1999 - maybe this will not be the last patent infringement suit we will see. IBM went to considerable lengths in 2004 to work out exactly what the PSI machine is - a real piece of hardware or just another emulator. It seems to think it walks like a duck, too. PSI has repeatedly denied that its system was an emulator - they'll now have a chance to convince a court. It took IBM from 29 March 2004 to 9 August 2004 to grant the licence. That's a fair length of time - enough for IBM to have determined that it was an emulation system that would be expected to violate the ICA clause? -- Phil Payne http://www.isham-research.co.uk +44 7833 654 800 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
