All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
Your question comprises two different matters.
The first matter: What relates to the right of invention and business name.
The Islamic Fiqh Committee in its 5th conference held in
Firstly, the business name, the business address, logo, editing and invention, are personal rights of their owners. Today, it has a considerable monetary value in contemporary traditions as people invest on them. These rights are recognized by Islamic Jurisprudence, so it is not permissible to transgress these rights.
Secondly, it is permissible for the owner to do as he pleases in relation to his business name, business address, logo, or transfer any of it with a monetary value if there is no harm or cheating, as this is considered as a monetary right of ownership.
Thirdly, the copyright and rights of invention are Islamicly protected. Their owners have the right to run them, and therefore it is not permissible to transgress these rights.
The second matter:
What relates to the selling or renting the right of invention or the business name with some benefits:
This is not permissible because the yearly benefit rate is unknown, it could be small and it could be a large benefit, or it could be that there is no benefit at all. So the matter is unknown, and this is considered form of cheating, and the Prophet forbade us from cheating.
Therefore, the solution for this kind of transaction is to sell or rent the right of invention or the business name for a known price rather than for a portion of an unknown amount.
Allaah knows best.
