However, Optimal Robotics Corporation previously had designed and implemented their own self-check out system, which they reported to have developed completely independently of International Automated Systems. A press release by Optimal Robotics on January 24, 2004, states: "Optimal Robotics Corp. (NASDAQ: OPMR), today announced that it has entered into a settlement agreement with International Automated Systems, Inc. (IAS), which brings to a close the patent lawsuit between the parties. In accordance with the agreement, IAS will receive a sum that is not considered to be material to Optimal."
This situation led to Optimal Robotics Corporation creating their own self-checkout system without any external influence from International Automated Systems. A press statement by Optimal Robotics on January 24, 2004, states: "Optimal Robotics Corp. (NASDAQ: OPMR), today announced that it has settled a patent dispute with International Automated Systems, Inc. (IAS). As part of the agreement, IAS will receive a payment that is not significant to Optimal."
