Patent Invalidity and Patent Infringement are different aspects of Intellectual property but often goes hand-to-hand. Patent infringement arises when the rights granted to the Patentee are under threat i.e. if the product or process under the patent are commercialized without the consent of the Patentee. Patent invalidation is the defense of the infringer in the suit of Patent Infringement i.e. the defender tries to invalidate the patent itself and tries to prove that those rights either never existed or wrongly granted. TSR helps the clients in both the aspects. Through the Patent watch we helps in identifying the potential infringer or provide technical guidance in Patent invalidation process.
