Patent infringement comprises of the illegal making, using or even offering for a sale or selling any patented invention within the country or its territories, or importing it into the country of any patented invention during the period of the patent protection. The scope of Patent Infringement protection may vary from country to country, as the patent is examined voluntarily by the patent office established in each country or region and may have some difference in patentability, so that a granted patent is difficult to carry out worldwide. In many countries, a use is mandatory to be commercial or to be for a commercial purpose so as to constitute patent infringement. When patent infringement takes place, the Patent filing agent may sue for its relief by Patent drafting in the concerned Federal court. The Patent filing agent may also ask court for a ban to prevent the continuation of the patent infringement and may also ask the court for reimbursement of damages occured due to the patent infringement. Patent Infringement and its Claims In such a suit, the suspect may raise the question of the genuineness of the patent, which is then judged by the court. The litigant may also try to prove that what is being done does not constitute any infringement. Infringement is judged primarily by the language of claims of the patent and, if what the suspect or litigant is making does not fall within the language of any of the claims of the patent, there is no literal infringement. Suits of infringement of patents abide by the rules of procedure of the courts. In case of the United States Government if it infringes a patent, the Patent filing agent has to reimburse for damages in the United States Court of Federal Claims. The Government can use any patented invention without taking permission of the patentee, but the patentee is entitled to obtain compensation for the use by the Government. The US Patent Office has no area of authority over questions relating to infringement of patents. In examining patent infringement analysis, no assurance is made as to whether the invention pursued to be patented infringes any prior patent. An improvement invention can be patented, but it might infringe a prior unceased patent for the invention improved upon, if there is any. Patent law dictates the rules for patents. The USPTO administers all patent laws relating to the Patent drafting and various other provisions nodal to patents. They examine your patent applications and grant it when applicants are entitled to them.
