Patents and Intellectual Property
We rely on a combination of United States patents, trademarks, copyrights, trade secret law, employee non disclosure agreements and work-for-hire and non-disclosure agreements with independent contractors to protect and enforce our intellectual property rights. We also obtained patent assignments from each inventor named in our patent and patent applications. However, we do not have general assignment of inventions agreements with our former employees who are not named as inventors in our patent and patent applications, which could compromise the common law protection of our intellectual property.
On November 9, 2004, we were granted United States Patent No. 6816562 entitled Silicon Object Array with Unidirectional Segmented Bus Architecture. This patent covers our interconnect system consisting of nearest neighbor and party line connections that allow objects in our FPOA chip to communicate with other objects in the chip and to work together or independently. We believe that this patent is important to our competitive position because the technology protected by it is key to us being able to produce an FPOA chip that can achieve a one GHz clock speed. The patent expires on April 28, 2023.
In addition, we have filed or are in the process of filing United States patent applications for the following aspects of our technology:
· Integrated Circuit Layout Having Rectilinear Structure of Objectsapplication filed in January 2005;
· Boolean Logic Tree Reduction Circuitapplication filed in January 2004;
· Shift and Recode Multiplierapplication filed in April 2004;
· Leading Zero Counter for Binary Data Alignmentapplication filed in July 2004;
· Reconfigurable State Machineapplication filed in September 2004; and
· SystemC Signoff of Reconfigurable Signal Processing Platform Using Hardware-Cycle-Accurate Modelapplication filed in September 2004.
We currently hold common law trademark rights in the trademarks MathStar and FPOA, and we have pending federal trademark applications in the United States for the MathStar and FPOA trademarks. We do not have any trademarks registered outside the United States, nor do we have any trademark applications pending outside the United States. We also currently hold one domain name relating to our business, MathStar.com, which we believe is important to our brand recognition and overall success.
We believe our success will not be based solely on the protection of our intellectual property but more importantly on our ability to design, market and sell chips that meet the demand for new technologies and better performance. We plan to continue to develop new technology, and the methods we use to protect such technologies will depend on our evaluation of the relative benefits of obtaining such protection.
