Patent Bet Calculator
Work out the returns on a Patent — seven bets across three selections: three singles, three doubles and a treble. Enter your unit stake and odds, mark each selection as won or lost, and see exactly what the bet pays.
A Patent is 7 bets, so your total outlay is 7 × unit stake.
Your Results
A lost selection knocks out its single, both of its doubles and the treble; the remaining bets settle as normal.
How a Patent Is Calculated
A Patent covers three selections with seven separate bets: three singles, three doubles and one treble. Because every combination is covered, a single winner still returns something — the main reason bettors choose a Patent over a Trixie, which drops the singles.
Here is a £1 Patent (£7.00 total outlay) on selections at decimal odds of 2.00, 3.00 and 4.00, with all three winning:
| Bet | Calculation | Returns |
|---|---|---|
| Single: Selection 1 | £1 × 2.00 | £2.00 |
| Single: Selection 2 | £1 × 3.00 | £3.00 |
| Single: Selection 3 | £1 × 4.00 | £4.00 |
| Double: Selections 1 + 2 | £1 × 2.00 × 3.00 | £6.00 |
| Double: Selections 1 + 3 | £1 × 2.00 × 4.00 | £8.00 |
| Double: Selections 2 + 3 | £1 × 3.00 × 4.00 | £12.00 |
| Treble: All three | £1 × 2.00 × 3.00 × 4.00 | £24.00 |
Total return: £59.00 from £7.00 staked — a profit of £52.00. If only the 4.00 selection had won, the bet would return £4.00 for a £3.00 loss; two winners at 2.00 and 4.00 would return £14.00 (two singles plus one double) for a £7.00 profit.

Frequently Asked Questions
What is a Patent bet?
A Patent is seven bets across three selections: three singles, three doubles and one treble. A £1 unit stake therefore costs £7.00 in total. Every selection appears in four of the seven bets, so each winner contributes to several returns at once.
What is the difference between a Patent and a Trixie?
A Trixie uses the same three selections but only four bets — the three doubles and the treble — so it costs £4.00 per £1 unit instead of £7.00. The trade-off: with just one winner a Trixie returns nothing, while a Patent still pays the winning single.
How many winners do I need to make a profit on a Patent?
One winner only covers the £7.00 outlay if its decimal odds are above 7.00 — a £1 Patent with a single winner at 8.00 returns £8.00. At typical odds you need at least two winners: two at 2.00 and 4.00 return £14.00, doubling the outlay.
Is a Patent better than a Lucky 15?
They cover different numbers of selections: a Patent is 7 bets on three picks, a Lucky 15 is 15 bets on four, so a Lucky 15 costs more than twice as much at the same unit stake. If you have four selections, work the numbers with the Lucky 15 Calculator and compare.
Multiple bets like the Patent stake seven times your unit stake, so set that stake with your total outlay in mind. 18+. Please bet responsibly — see our responsible gambling resources.
