Patent Litigation is a legal process that unfolds when someone who owns a patent for a particular invention enforces his/her/it’s right by suing another for manufacturing or selling the invention without permission. Third parties try to use other’s inventions even if the patent is granted without taking permission from the patent holder. For such cases, the patent holder can file suit for infringement against the third party and can demand an injunction as well as damages. The third-party on the other hand can file a suit for dismissal of the grant of a patent to the patent holder on the ground of existence of prior art, the obviousness of an invention, lack of novelty, etc.
