Just have a simple question, the ATB system (Active Time Battle) from Final Fantasy has been patent in the past (i think 1992 on july). I am interested in making a turn based game based on the Charge Time System which is virtually a gauge filling up (using the speed value of the unit) until you reach 100 then the unit can act but nobody else can interfert the action of the unit. I am building an internal list from this to simulate turns of each units so i can see when units are actually playing.. then if the speed attribute change the list is updated.
Here the info on the patent found on http://en.wikipedia.org/wiki/Gameplay_of_Final_Fantasy :
A major departure from this system came in Final Fantasy IV, when Hiroyuki Ito introduced the "Active Time Battle" (ATB) system, where the time-keeping mechanism does not stop whilst the play selects commands. Square filed a Japanese patent application related to the ATB system on July 16, 1991 and a corresponding US application on March 16, 1992. One Japanese patent (JP2794230) and two US patents (US5390937 and US5649862)
So my main question is : Is my system an infrigement of this patent ?
Would love also some answers on this in the answer..
1- Is the Charge Time System from Final Fantasy patented ? 2- What is the Active Time System patent about ? It is the mechanic ? or the carbridge system which the ATS is based on ?
