Praise be to Allah.
There is nothing wrong with a company or manufacturer manufacturing a product for a client, and putting his name on this product so that it is a tradename or trademark, instead of putting the manufacturer’s name on it, so long as there is no intent to deceive. It is not permissible for the client to make anyone think that he manufactured the product himself, or made it in his own factory when in fact it was manufactured by someone else, because this is deceit and a false claim. The Messenger of Allah (blessings and peace of Allah be upon him) said: “The one who pretends to have been given something that he was not given is like the one who wears two garments of falsehood.” Narrated by al-Bukhaari (5219) and Muslim (2129).
It is permissible for the manufacturer to give his trademark or tradename to someone else, in return for payment or for free, on condition that there is no intention of deceit.
It says in a statement of the Islamic Fiqh Council, issued during its fifth conference in Kuwait, 1409 AH/1988 CE:
Trade names, trademarks, copyright and patents are all rights which belong exclusively to their owners. In modern times they have come to have a considerable monetary value. These rights are recognized according to sharee‘ah, and they should not be transgressed.
It is permissible to dispose of (by buying and selling) a trade name or a trademark, and to transfer any of them in return for monetary compensation, so long as there is no cheating or deception, on the grounds that this comes under the heading of financial rights.
Copyright and patents are protected by sharee‘ah. Their owners have the right to dispose of them and nobody has the right to transgress these rights.
