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.
