4. Who needs to become an adopter of the MHL Consortium?

Companies require a license to design, make, sell, lease or promote MHL products, components or IP cores. Companies may also choose to become MHL Adopters to access the MHL specification even if they do not intend to undertake the activities above. This license can be acquired directly by becoming an Adopter or in some cases may be sublicensed from an MHL Adopter. The following principles may be helpful in understanding if an organization needs to become an adopter:

  • The organization that has the legal rights to a brand used on a product (such as a cable, device, component or IP core) branded with or marketed with an MHL trademark, MUST become an MHL Adopter.
  • Subject to some limitations MHL Adopters may sublicense certain limited rights to enable others to design, make, re-sell or distribute an MHL product, component or IP core on their behalf.

Please note that we intend this FAQ as a general guide. We recommend that all organizations with questions about how MHL licensing may apply to their situation conduct a legal review of the MHL Adopters Agreement. If you do not have a copy of the MHL Adopters Agreement you can obtain a copy by submitting your details here.
