Patents by Inventor Miho Yokokawa

Miho Yokokawa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8664533
    Abstract: A substrate having a transparent conductive layer has a transparent conductive pattern that is not easily visually recognizable by a naked human eye on a transparent substrate and can be formed by a simple and efficient method. In the case where a transparent conductive pattern is formed on a transparent substrate, the pattern region does not include conductive regions covered with uniform transparent conductive films or a high-resistance region that is not covered with the transparent conductive film, the high-resistance region electrically insulating the conductive regions. Instead of the conductive regions or the high-resistance region, the inventors use a region having a structure including a mixture of a portion covered with the transparent conductive film and a portion not covered with the transparent conductive film, thereby solving the foregoing visual recognition issue.
