• A grant by a nation or group of nations to an inventor or his assignee conferring upon a right to exclude others from making using, selling, offering for sale and importing his invention for a limited period of time in lieu of the disclosure of the invention in a patent specification.
  • Patent right is a qualified right
  • It does not automatically give the owner the right to exploit his invention. But certainly gives the right to restrict others from exploiting his invention. The patent right is territorial in nature. A patent granted by India is valid in India only. Similarly a patent granted in USA is valid in USA only. There is nothing called “World patent” or “International patent”
