Worked examples

With one winner, only its single pays. Whether that covers the £7 stake depends on the price:

A second winner adds its single and a double, which is where the Patent starts to pay well:

Each way Patents

An each way Patent is 14 bets. The place part is a second Patent at place odds, so a selection that only places still returns something through its place single.

Patent, Trixie or Lucky 15?

A Trixie is a Patent without the singles: cheaper, but it needs two winners. A Lucky 15 is the same idea as a Patent with four selections instead of three, making 15 bets.

Common questions

How much does a Patent cost?

Seven times your stake. A £1 Patent costs £7, and each way doubles it to 14 bets, so £14 at £1 a bet.

Do bookmakers pay bonuses on a Patent?

Some do, in a similar way to Lucky 15s, for example by boosting the odds when only one selection wins. It varies between bookmakers and is often limited to horse racing, so check the terms. The calculator shows standard returns.

What happens if one selection is a non-runner?

Its single returns the stake, the doubles that include it become singles on the other selection, and the treble becomes a double.
