Patent Portfolio
We maintain and support an active program to protect our intellectual property, primarily through the filing of patent applications and the defense of issued patents against infringement. Our patents and patent applications cover important inventions in memory cell architecture, cross-point arrays, logic chip and host interfaces and applications of resistive random access memory, including CMOx™. We have a program to file applications and obtain patents in the United States and in selected foreign countries where we believe filing for such protection is appropriate. In some instances, obtaining appropriate levels of protection may involve prosecuting continuation and counterpart patent applications based on a common parent application.
