A patent gives an inventor a set of exclusive legal rights to his or her invention for a limited period of time. Chief among these rights: Patent holders have exclusive authority to manufacturer, sell, distribute and license inventions for the duration of the patent's life. If you are individual or a business that has an invention, talk to patent attorneys or intellectual property lawyers immediately. The law firm can help determine if your invention qualifies for a patent or potentially infringes on an existing patent, can guide you through the patent application process and can work with you to enforce your patent against potential infringers. If you've been accused of infringing on another party's patent, your lawyer can defend you against such allegations or attempt to negotiate a licensing agreement with the patent holder.
