Contact Us

We welcome inquiries from prospective clients.

Before contacting us about selling or licensing out patents, please confirm that:

  • Patents must be granted in the US, Europe, or China.
    Portfolios including only provisional patents or pending patent applications do not have market value.
    Patents not granted in at least the US, Europe, or China generally do not have market value.
  • There is a minimum portfolio size.
    We do not market portfolios with only one or two patent families in the high-tech industries—semiconductors, electronics, IT, and telecommunications. Products in these industries rely on thousands of patents. Therefore, companies have no interest in buying or licensing small patent portfolios. For other industries, there is no minimum portfolio size.
