A Patent is a classic multiple bet made up of 3 selections, combined into 7 separate bets: 3 singles, 3 doubles, and 1 treble. Unlike a straight treble, a Patent still pays out even if only one of your three selections wins.

This calculator lets you enter your three selections’ odds and results, then instantly see exactly which of the 7 bets won, how much each one returned, and your overall profit or loss.
Because a Patent covers every possible winning combination of your three picks, it’s a popular choice for bettors who want treble-style upside without losing everything on a single selection letting them down.
π How to Use the Patent Calculator
Enter the decimal odds for each of your three selections, then toggle each one to Won or Lost based on the actual result. Set your Unit Stake, which is applied to each of the 7 individual bets.
A Patent always contains exactly 7 bets from 3 selections, so your total outlay is always 7 times your unit stake.
The results panel breaks down every single one of the 7 bets, showing which ones won and exactly how much each contributed to your total return.
π’ Calculator Fields Explained
Unit Stake – The stake applied to each individual bet within the Patent, not the total outlay.
Selection Odds – The decimal odds for each of your three individual selections.
Won / Lost Toggle – Marks whether that specific selection’s outcome actually happened.
π° Understanding the Results
| Result Field | What It Means |
|---|---|
| Total Return | The combined payout from every winning bet within the Patent |
| Total Stake (7 bets) | Your unit stake multiplied by 7, the total amount risked |
| Net Profit | Total return minus total stake |
| Bet Breakdown Table | Each of the 7 individual bets, whether it won, and its exact return |
The breakdown table is where a Patent’s real appeal becomes clear, since even a single winning selection still returns something through its corresponding single bet.
A Patent’s total stake is always 7 times your unit stake, which surprises bettors who assume a “Β£1 Patent” only risks Β£1.
Even if only one of your three selections wins, a Patent still returns a payout through that selection’s single bet. This is the core structural advantage over a straight treble.
π Calculation Formulas
| Bet Type | Combination |
|---|---|
| 3 Singles | Each selection individually |
| 3 Doubles | Every possible pair of the 3 selections |
| 1 Treble | All 3 selections combined |
Each of the 7 bets only pays out if every selection within that specific bet wins β a double needs both its legs to win, not just one.
The total Patent return is simply the sum of whatever each of these 7 individual bets pays out based on your actual results.
π Practical Examples
Example 1 – All three win: Odds of 2.50, 3.00, and 1.80 with a Β£1 unit stake, all winning. Every one of the 7 bets pays out, for a total return of Β£42.90 from a Β£7 stake.
Example 2 – Two of three win: Same odds, but only the first two selections win. The 2 relevant singles, 1 relevant double, and the treble all lose (since the treble needs all 3). Total return comes from 2 singles and 1 double only.
Losing just one selection out of three doesn’t wipe out the entire Patent β it only removes the bets that specifically included that losing selection.
Example 3 – Only one wins: Same odds, but only the third selection (1.80) wins. Only that single bet returns anything; all doubles and the treble lose since each needs at least one more winning leg.
A Patent with only one winning selection out of three can still return a small profit purely through that one single bet. This is the safety net a straight treble simply doesn’t offer.
π‘ Tips & Best Practices
Use a Patent when you’re reasonably confident in all three selections but want some protection if just one lets you down, rather than betting a straight treble.
Remember your total stake is 7 units, not 1, when budgeting for a Patent β this is the single most common miscalculation new bettors make.
Compare a Patent’s total cost and potential return against a Trixie (the same structure minus the singles) to decide which suits your risk tolerance.
- Check whether your bookmaker offers each-way Patents for horse racing selections, which double the total number of bets to 14
- Keep unit stakes small when testing higher-risk selections, since the 7x stake multiplier adds up quickly
Understanding the full 7-bet cost upfront is what separates a well-planned Patent from an expensive surprise.
Finally, use the breakdown table to learn exactly which combinations of your selections would have paid out, which helps refine your multiple-betting strategy over time.
β οΈ Common Mistakes to Avoid
Assuming the unit stake is the total stake
Many new bettors think a “Β£2 Patent” costs Β£2 total, when it actually costs Β£14 since the stake applies to all 7 individual bets.
Confusing the unit stake with the total stake is one of the most common and costly errors in multiple betting.
Always multiply your intended unit stake by 7 before placing a Patent to know your true total outlay.
Forgetting that doubles require both legs to win
It’s easy to assume a double partially pays out if only one of its two legs wins, but multiple bets require every included leg to win.
Forgetting that every leg within a specific bet must win is a costly misunderstanding of how multiples like doubles and trebles actually settle.
Misunderstanding which specific bets require which legs to win is consistently the costliest mistake in Patent betting. Only the exact combinations that fully hit will return anything.
π― When to Use This Calculator
Use this calculator when you’ve picked three selections and want to see, before or after the event, exactly how a Patent structure would pay out compared to betting them individually or as a straight treble.
A Patent rewards you for being right about any combination of your selections, not just all three at once.

β Frequently Asked Questions
How many bets are in a Patent?
A Patent always contains exactly 7 bets: 3 singles, 3 doubles, and 1 treble, derived from 3 selections.
For example, with selections A, B, and C, the 7 bets are A, B, C, AB, AC, BC, and ABC.
What’s the difference between a Patent and a Trixie?
A Trixie uses the same 3 selections but drops the 3 singles, leaving only 4 bets: 3 doubles and 1 treble.
This means a Trixie costs less than a Patent at the same unit stake but offers no return if only one selection wins.
Do I need all three selections to win to get a return?
No, a Patent pays out something as long as at least one of your three selections wins, through that selection’s individual single bet.
Even a single winning selection out of three still triggers a payout through the corresponding single bet in a Patent.
This is precisely why Patents are popular with bettors who want some protection against one selection letting them down.
How much does a Patent cost?
Total cost equals your unit stake multiplied by 7, since a Patent always contains exactly 7 individual bets.
A Β£5 unit stake Patent costs Β£35 total, not Β£5, since the stake applies across all 7 bets.
Can I use a Patent for horse racing each-way bets?
Yes, an each-way Patent doubles every bet into a win portion and a place portion, resulting in 14 total bets instead of 7.
This significantly increases the total stake required, so always confirm the each-way terms and total cost before placing it.
