Patent

You have built something that works. You want to stop a competitor from simply making the same thing. A patent is the legal instrument that lets you do that - but only in exchange for telling the public exactly how it works.

In simple words

A time-limited right, granted by the State, to stop other people from making, using, selling or importing your invention without permission - given in return for a full public description of it.

Think of it as

A twenty-year monopoly bought with a disclosure.

Why it matters

Almost every misunderstanding about patents comes from missing the bargain at the centre of them. You are not being given secrecy; you are giving up secrecy. What you get back is a right to exclude, in one country, for a fixed period, and only over what your claims actually say.

A simple example

You invent a valve that halves leakage in irrigation pipes. If it is granted, an Indian patent lets you stop others in India from making or selling that valve for twenty years from your filing date. It does not stop anyone in Kenya, and it does not stop someone whose valve works differently enough to fall outside your claims.

Common mistake

Treating a patent as ownership of an idea. A patent covers what is claimed, in the country that granted it, for as long as the renewal fees are paid.

Where it comes from

Patents Act 1970 - definition of “patent” in section 2(1)(m); rights of the patentee in section 48; term in section 53
