Paths to protection

Ways to protect your invention

Patents are a way of protecting your inventions. By filing a successful patent you will be awarded a monopoly to exploit your invention for a period of time.

National Patents are the most effective way of defending your invention if you only require protection in a single jurisdiction. If this is not enough for your needs, this country has signed international agreements on patents, which facilitate their internationalization:

PCT (Patent Cooperation Treaty)

The PCT system allows simplified international patent applications which in turn eases national filings.

EPO (European Patent Organization)

EPO is responsible for the proceedings until grant of European Patent Applications.
