Patent Law

Patents are issued for four types of inventions such as devices, products, materials, and methods and an invention must be unique and useful for it to be patented. Patent law protects "original inventions and processes" including genetically engineered life forms. The term "patent" originates from the Latin word patere which means "to lay open", meaning make available for public inspection, and the term letters patent, which originally denoted royal decrees granting exclusive rights to certain individuals or businesses. A patent is a set of exclusive rights granted by a state to a person for a fixed period of time in exchange for the regulated, public disclosure of certain details of a device, method, process or composition of matter, known as an invention which is new, inventive, and useful or industrially applicable. The grant of patent gives an inventor the right to exclude others from exploiting or   making capital out of the invention for a limited period of time. The first patent was granted by Henry VI in 1449 to a Flemish man a 20 year monopoly on the manufacture of stained glass. The philosophy behind the patent system is to encourage inventions by promoting their protection and helping the inventor capitalize.

The exclusive right granted a patentee is the right to prevent others from making, using, selling, offering to sell or importing the claimed invention. A patent is, in effect, a limited property right that the government offers to inventors in exchange for their agreement to share the details of their inventions with the public. Patents are enforced through civil lawsuits.

Typically, the patent owner will seek monetary compensation for past infringement, and will seek an injunction prohibiting the defendant from engaging in future acts of infringement. An important limitation on the ability of a patent owner to successfully assert his or her patent in civil litigation is the accused infringer's right to challenge the validity of that patent. Patent licensing agreements are effectively contracts in which the patent owner (the licensor) agrees not to sue the licensee for infringement of the licensor's patent rights.

Justifications for granting patents:

Patent rights create an incentive for companies to develop workarounds to patented inventions, thereby creating improved or alternative technologies that might not otherwise have been developed. Patents facilitate and encourage disclosure of innovations into the public domain for the common good. When a patent's term has expired, the public record ensures that the patentee's idea is not lost to humanity. Patents incentivize economically efficient research and development. Without patent protection, corporations would be much more conservative about the research and development investments they made, as third parties would be free to exploit any developments.
