‘A patent for an invention is grant of exclusive rights to make, use and sell the invention for a limited period of 20 years. The patent grant excludes others from making, using, or selling the invention. Patent protection does not start until the actual grant of a patent. A patent cannot be obtained on a mere idea or suggestion. Patent applications are examined for both technical and legal merit.’ 
Any invention is patentable, if it meets the following 3 requirements:
- Is new/novel and does not form part of the state of the art;
- Involves an inventive step; and
- Is capable of industrial application.
In Pakistan, patents are applied mainly for products and processes for medicines/pharmaceuticals, industrial machines, electronics.
