    Indirect infringement is not explicitly dealt with in the Turkish IP Law. However, the legislator confers, via Article 86 of the Industrial Property Code (IPC), a right to the patent holder to prevent third parties from supplying essential elements of the invention to unauthorised people, which will eventually lead to the working of the patented invention. In order for this provision to be implemented, third parties must be aware that these elements or instruments are sufficient to work the invention, and should be aware that they will be used for this purpose, or this situation should be clear enough.
