Thanks for posting this.
I read through the patent interpration, and it is obvious the judge was not sold on the defense. He, in my opinion, does not adqautely examine the other software in use before the MD display by TT.
But more importantly, his interpretation of the patents means that any other program with simultaneous use of a static price display and single action entry is in violation. His interpretation absolutely links them to validate the patents. When I read the patents, my initial understanding was TT was trying to patent all of these attributes individually, not the simultaneous use ot these attributes.
I take this to mean you can copy X_Trader in its current form, as long as you change one attribute, such as requiring an entry confirmation. This would require two actions, such as a click and a keystroke, or perhaps two different keystrokes. Pressing, say, the enter key followed by the space bar, or perhaps an arrow key corresponding to a particular entry order folled by a return, would be sufficient to circumvent these patents (accoring to this ruling). And these keystrokes could be execured in less than half of a second.
Regardless, I dont' see TT being able to strong-arm the exchanges ibased on the language in this ruling. It leaves the opportunity for near identical copycat to enter the market.
P.S. I am neither a lawyer nor an X_Trader user (never have been).
