Intellectual property rights
Question

What do the Muslim fuqaha’ say about intellectual property rights such as trade names, trademarks, copyright and patents?
Praise be to Allah.Firstly:
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 financial value. These rights are recognized according to sharee’ah, and they should not be violated. 
Secondly:
It is permissible to buy or sell 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. 
Thirdly:
Copyright and patents are protected by sharee’ah. Their owners have the right to buy or sell them and nobody has the right to violate these rights. And Allaah knows best.
