List of the Patent Services


        A Patent is a legal title granting its holder the exclusive right to use an invention for a limited area and time by stopping others from, among other things, making, using or selling it without authorisation.

        All patent applications and granted patents are published. They provide a useful indicator for monitoring market trends, as well as being a source of information about innovative developments in all areas of technology, and such are an effective means of avoiding parallel developments and duplicate research.

The patent system plays a major part in the transfer of technology, which is a stimulus to technical innovation.

The exclusive right to exploit an invention commercially makes it easier for companies to finance research and development.

As exclusive rights, patents strengthen a company’s market position.

Patent inventions encourage research into alternative solutions.

The licensing of patents promotes the dissemination of new technologies.

        Patents indicate the level of innovative activity in a particular market. They generate new investment and are a motivating force behind technical progress.

        What is patent information? The term Patent information covers all types of technical information, market information, legal information, and information about companies that you can obtain from documents published by patent offices.

        Patent data help us to recognise technological trends at an early stage and give us an idea of other R & D programmes underway in our field. Patents are an essential source of information to us when we come to formulating our own R & D programmes and later converting them into technology, products and markets.
