Patent calculator
A Patent is 7 bets on 3 selections: 3 singles, 3 doubles and 1 treble. It includes singles, so a single winner still returns something.
Enter the odds as fractions (5/2), decimals (3.50) or American odds (+150) and mark each result. Switch on each-way to add the place part.
What a Patent is made of
| Part | Bets |
|---|---|
| Singles | 3 |
| Doubles | 3 |
| Treble | 1 |
| Total | 7 |
| Each-way (win and place parts) | 14 |
At £1 a bet a Patent costs £7. Each-way doubles the bets to 14, so £1 each-way costs £14. The place part pays a fraction of the odds, usually 1/4 or 1/5, for each selection that wins or is placed.
How many winners you need
| Winners | Return | Profit or loss |
|---|---|---|
| 0 | 0 | −7 |
| 1 | 3 | −4 |
| 2 | 15 | +8 |
| 3 | 63 | +56 |
With 2 winners at 2/1 a Patent returns 15 for a stake of 7. Longer odds need fewer winners and shorter odds more, so try your own prices in the calculator.

Questions
How many bets are in a Patent?
7: 3 singles, 3 doubles and 1 treble. Each-way it is 14 bets, a win part and a place part for each.
How much does a £1 each-way Patent cost?
£14: £7 for the win bets and £7 for the place bets. At 50p each-way it costs £7; at 10p each-way, £1.40.
What is the difference between a Patent and a Trixie?
Both use 3 selections. A Patent is a Trixie plus 3 singles: 7 bets against 4. The singles mean one winner still returns something, at the cost of 3 more stakes.
Does a Patent improve my chances of winning?
No. It spreads the stake over many bets, so fewer winners still return something, but every selection carries the bookmaker's margin and each double, treble and accumulator multiplies it. See what multiples really cost.
What about bonuses on a Patent?
Some bookmakers add extras, for example double or treble the odds when only one selection wins, or a bonus when every selection wins. The terms differ between bookmakers and races; the calculator shows the standard returns without them.
