The patent bet is one of the most popular full-coverage multiple bets in sports betting — and for good reason. Combining three selections into seven individual bets, it guarantees a return whenever at least one of your picks wins, making it a structurally safer alternative to a treble for bettors who want upside on multiple selections without the all-or-nothing risk. Understanding how patent betting works — and where it fits your strategy — is what separates disciplined bettors from those who routinely stake more than they should.
In this guide you will learn exactly what a patent bet is, how each of its seven components is calculated, when a patent outperforms or underperforms competing bet types such as the Trixie or Heinz, and how to build a sound staking strategy around it. Real numbers are used throughout — no vague promises about "big returns," just honest maths.
What Is a Patent Bet?
A patent bet is a seven-bet wager covering three selections: three singles, three doubles, and one treble. All seven bets are placed simultaneously at a single stake-per-bet unit, meaning a £1 patent costs £7 in total. The defining characteristic is the three singles — they ensure that even if two of your selections lose, you still receive a return on the one winner.
The name "patent" derives from British horse racing slang dating to the mid-twentieth century, where bookmakers popularised full-coverage bets under proprietary names. Today virtually every UK and Irish sportsbook — and a growing number of international platforms — list the patent as a standard bet type, often available via a dedicated "patent" option in the multiple-bet slip.
The key structural difference from a Trixie (also three selections) is exactly those three singles. A Trixie contains only four bets — three doubles and a treble — requiring a minimum of two winning selections to return anything. A patent, by contrast, pays out on a single winner, making it a better fit when you have high confidence in one selection but less certainty about the others.
How a Patent Bet Works: The 7 Bets Broken Down
To place a patent, you select three events — call them Selection A, Selection B, and Selection C. The seven component bets are:
| # | Bet Type | Selections Covered | Wins Needed to Return |
|---|---|---|---|
| 1 | Single | A only | 1 |
| 2 | Single | B only | 1 |
| 3 | Single | C only | 1 |
| 4 | Double | A + B | 2 |
| 5 | Double | A + C | 2 |
| 6 | Double | B + C | 2 |
| 7 | Treble | A + B + C | 3 |
Each component bet is calculated independently using its own odds. Returns from singles do not carry over into doubles — every line stands alone. If a selection is void (the event is cancelled, for example), that selection is removed and the remaining bets are recalculated as if the patent contained only two selections, effectively reducing to a three-bet cover on the surviving picks.
Patent Bet Example Walkthrough
Step-by-Step Patent Bet Calculation
Stake: £1 per line × 7 bets = £7 total outlay
Selections:
- Selection A: Horse racing — Odds 3/1 (decimal 4.0) → Wins
- Selection B: Football — Odds 2/1 (decimal 3.0) → Wins
- Selection C: Tennis — Odds 1/1 (decimal 2.0) → Loses
Calculating each line (£1 stake per bet):
- Single A: £1 × 4.0 = £4.00
- Single B: £1 × 3.0 = £3.00
- Single C: Loses — £0.00
- Double A+B: £1 × 4.0 × 3.0 = £12.00
- Double A+C: Loses (C lost) — £0.00
- Double B+C: Loses (C lost) — £0.00
- Treble A+B+C: Loses (C lost) — £0.00
Total return: £4 + £3 + £12 = £19.00
Net profit: £19.00 − £7.00 = £12.00
Two winners from three selections yielded a 171% return on stake — with the patent structure providing the double payout that a simple accumulator on all three would have forfeited entirely.
Now consider the worst-case scenario: only one selection wins. Using Selection A at 4.0 with a £1 patent:
- Single A returns £4.00
- All doubles and the treble lose
- Net: −£3.00 (you recover £4 on a £7 outlay)
That partial return is what makes the patent structurally attractive — no other three-selection multiple guarantees any return from a single winner.
Patent Bet vs. Other Multiple Bets
Understanding how the patent compares to competing bet structures helps you choose the right tool for each situation. The most relevant comparisons are the Trixie, Lucky 15, and straight accumulator.
| Bet Type | Selections | Total Bets | Min. Winners to Return | Includes Singles? | Relative Cost |
|---|---|---|---|---|---|
| Patent | 3 | 7 | 1 | Yes | Medium |
| Trixie | 3 | 4 | 2 | No | Low |
| Treble | 3 | 1 | 3 | No | Very Low |
| Lucky 15 | 4 | 15 | 1 | Yes | High |
| Heinz | 6 | 57 | 2 | No | Very High |
The Trixie costs 43% less than a patent (4 bets vs. 7) but offers no protection if only one selection wins. For bettors on tighter bankrolls who are confident in at least two selections, the Trixie is the more capital-efficient choice. The patent is better when your conviction is concentrated on one or two "anchor" picks and the third is speculative.
The Lucky 15 extends the same full-coverage logic to four selections (15 bets), including four singles, six doubles, four trebles, and a fourfold. Many bookmakers offer bonuses — typically a 10–25% consolation bonus when only one selection wins — which can make the Lucky 15 mathematically superior to the patent for four-selection plays, assuming those bonuses apply.
Patent Betting Strategy: When to Use It
Identifying the Right Selections for a Patent
A patent works best when your three selections have odds between 2.0 and 5.0 (evens to 4/1). At very short odds (below 1.5), the seven-bet structure costs more than the singles return, eroding value. At very long odds (above 10.0), a Trixie or straight treble will produce a larger upside if all three land — the singles become almost irrelevant to total return.
The sweet spot is a mixed-odds patent: one shorter-priced "banker" around 2.0, one mid-range selection at 3.0–4.0, and one longer-priced pick at 5.0–6.0. This spread means the singles provide meaningful insurance while the doubles and treble deliver outsized returns if multiple picks land.
Staking and Bankroll Discipline
Because a patent multiplies your unit stake by seven, staking discipline is critical. A common mistake is treating the patent as if it were a single bet — choosing a "comfortable" stake, then not realising you have committed seven times that amount.
Rule of thumb: your per-line stake on a patent should be no more than 1–2% of your session bankroll, making total outlay 7–14%. For a £500 session bankroll, that means a maximum of £1–£2 per line (£7–£14 total). Never chase losses with patent bets at higher stakes — the guaranteed partial return on a single winner can create a false sense of security that encourages over-staking.
Using Each-Way Patents in Horse Racing
The patent is especially popular in horse racing, where each-way betting is standard. An each-way patent doubles the number of lines to 14 (seven win bets and seven place bets), doubling the total cost. The place component — typically governed by standard industry terms set under UKGC-regulated bookmakers at one-quarter odds for races with 8+ runners — provides an additional safety net, particularly on longer-priced selections that place but do not win.
For a £0.50 each-way patent (14 × £0.50 = £7.00 total), a single placed selection at 8/1 (decimal 9.0) with a 1/4 place payout at 2.25 decimal returns £1.125 — a partial loss but meaningful compared to losing all seven bets outright.
Patent Bet Do's and Don'ts
Do's
- Calculate total stake before placing — multiply your unit stake by 7
- Use a patent when you have one strong "anchor" selection and two speculative picks
- Consider each-way patents in horse racing for additional place coverage
- Shop around for the best available odds across each individual selection
- Set a loss limit per session and stick to it regardless of partial returns
- Use a reputable patent calculator to verify returns before placing
Don'ts
- Don't treat a partial return as a "win" and raise stakes to recover
- Don't use a patent on three short-priced favourites at odds below 1.5 — cost exceeds value
- Don't ignore the house margin: each additional leg in an accumulator multiplies the bookmaker's edge
- Don't place a patent across correlated events (e.g. two players in the same match)
- Don't confuse a patent with a Trixie — the Trixie has no singles and requires two winners
- Don't gamble with funds you cannot afford to lose
Understanding the Bookmaker's Margin in Patent Bets
Every individual selection in a patent carries the bookmaker's overround — their built-in margin, typically 5–8% per event in UK sports betting. Because a patent aggregates seven separate bets across three selections, that margin compounds. The treble line alone, if priced at a typical UK overround, carries an effective bookmaker edge three times the single-event margin. This does not mean patent bets are poor value — it means you should prioritise selections where you believe the true probability is higher than the implied odds, the cornerstone of any positive expected value approach.

Frequently Asked Questions
What is a patent bet in horse racing?
A patent bet in horse racing is a seven-bet wager across three selections — three singles, three doubles, and one treble — where all bets are calculated independently. It is especially popular in horse racing because each selection can also be placed each-way, doubling the bet count to 14 lines and providing place returns even when a selection finishes second or third rather than winning outright. The each-way patent is one of the most widely used full-coverage bets among British and Irish racing punters.
How much does a patent bet cost?
A patent bet costs seven times your unit stake. If your stake per line is £1, the total outlay is £7. If you opt for £0.50 per line, the cost is £3.50. For an each-way patent, multiply by 14 — a £0.50 each-way patent costs £7. The total cost is fixed regardless of how many selections win, so always confirm the per-line stake before placing. Many bookmakers display the total cost on the bet slip once you select the "patent" option.
What is the minimum number of winners needed for a patent bet to return a profit?
One winner is all you need to receive a return, but whether that return exceeds your £7 outlay depends entirely on the odds. For a £1 patent, you need the sole winner to be priced at odds greater than 7.0 (6/1) for the single alone to cover the total stake. In practice, a single winner at odds of 3.0–5.0 will return between £3 and £5, representing a partial loss rather than a net profit. To break even on the full patent stake from a single winner, that selection needs to be around 8.0 or higher.
Is a patent bet better than a Trixie?
It depends on your confidence level and bankroll. A Trixie (three doubles and a treble, four bets total) costs 43% less than a patent and delivers higher returns per pound staked if at least two selections win, because all of your stake is concentrated into fewer, higher-multiplying lines. However, a Trixie returns nothing if only one selection wins. A patent is better when you want insurance on a single winner — particularly if one of your three selections is a "banker" you are very confident in. For casual bettors or those building a horse racing accumulator around one strong fancy, the patent's safety net usually justifies the extra cost.
Can I place a patent bet on football?
Yes. A patent bet can be placed on any three selections across any sport or combination of sports, including football match results, Asian handicaps, over/under markets, tennis sets, basketball point spreads, and more. The only constraint is that all three selections must be available as singles on your chosen bookmaker's platform. Cross-sport patents — for example, one horse racing selection, one football selection, and one tennis selection — are perfectly valid and can be a useful way to spread risk across uncorrelated events.
What happens to a patent bet if one selection is void?
If one of the three selections in your patent is declared void — because the event was cancelled, a race was abandoned, or the market was settled as a no-bet — that selection is removed from all component bets. The remaining six bets are recalculated as if the patent were a three-bet structure: specifically, two singles and one double on the two surviving selections. Your stake is recalculated accordingly, and most bookmakers will automatically refund the difference or reduce the total staked amount.
"The patent's three singles are not a concession to timidity — they are a precision instrument for managing variance across three selections when your conviction is unevenly distributed."— Daniel Cole
