What Is a Patent?
A Patent is a UK full-cover bet built from 3 selections. It is a Trixie plus the 3 singles, totalling 7 bets: 3 singles, 3 doubles, and 1 treble. One winner guarantees a return, so it is the cheapest entry point to full-cover betting.
Patents are popular on UK and Irish horse racing, particularly on three named horses at the same meeting. They sit alongside the Trixie (no singles, 4 bets) as a 3-selection alternative to the Lucky family. Patents do not use the Lucky-family bookmaker bonuses.
- 3 singles
- 3 doubles
- 1 treble accumulator
- 7 total bets per Patent
How a Patent Pays Out
Each of the 7 component bets settles independently. The singles guarantee a return on a single winner; the doubles and treble compound profit on multiple winners.
Stake: 1 unit per bet. 3 selections, all winners at decimal odds 2.00.
Singles: 3 x 2.00 = 6 units
Doubles: 3 x (2.00 x 2.00) = 12 units
Treble: 1 x (2.00 x 2.00 x 2.00) = 8 units
Total return: 26 units (stake 7)
Profit: 19 units (about 2.7x the total outlay)
If 2 selections win at 2.00, you collect 2 singles (4 units) plus the 1 double they share (4 units), total 8 units against the 7 unit stake. The Patent is the only 3-selection bet that pays a profit on 2 of 3 winners at even money.
Sample Patent Returns
All scenarios below assume 1 unit stake per bet (7 unit total outlay) with all selections at the same decimal odds.
| Winners | Odds Each | Return | Profit |
|---|---|---|---|
| 1 of 3 | 2.00 | 2 units | -5 units |
| 2 of 3 | 2.00 | 8 units | +1 unit |
| 3 of 3 | 2.00 | 26 units | +19 units |
| 3 of 3 | 3.00 | 84 units | +77 units |
| 3 of 3 | 5.00 | 320 units | +313 units |
Patents do not use the Lucky-family bookmaker bonuses. The calculator above reflects the raw 7-bet payout.
Common Mistakes to Avoid
A 5 unit Patent costs 35 units total, not 5. Always size your unit stake based on the 7x multiplier.
Patents do not pay double odds on a single winner or any all-winners bonus. Those offers apply to Lucky 15, 31, and 63 only. The Patent payout is the raw 7-bet sum.
Small differences on each leg compound across 4 winning combinations when all three land. Use an odds comparison tool to lock in the best price on every selection.
The 1-winner break-even point at 2.0 odds is a 3.5 priced selection. Each leg should still be a value bet, not a long-priced flier.
Frequently Asked Questions
What is a Patent bet?
A Patent is a UK full-cover bet made up of 7 separate bets across 3 selections: 3 singles, 3 doubles, and 1 treble. Only one selection needs to win for a return.
How many bets are in a Patent?
Exactly 7: 3 singles + 3 doubles + 1 treble. Your unit stake is multiplied by 7 to reach the total outlay.
How many winners do I need for a return?
Just one. A single winning selection pays out the matching single. Two winners add the double between them; three winners trigger all 7 bets.
What does a Patent pay if all three win at 2.00?
With a 1 unit stake per bet, the return is 26 units against a 7 unit outlay, a profit of 19 units (roughly 2.7x the total stake).
What is the difference between a Patent and a Trixie?
A Trixie is 4 bets: 3 doubles and 1 treble, no singles. The Patent adds the 3 singles, bringing the total to 7 bets and guaranteeing a return on a single winner.
What is the difference between a Patent and a Lucky 15?
A Patent uses 3 selections (7 bets). A Lucky 15 uses 4 selections (15 bets). The Lucky 15 adds a four-fold and twice as many trebles, plus access to the UK bookmaker bonuses.
What is the difference between a Patent and a Yankee?
A Yankee uses 4 selections (11 bets) with no singles. The Patent uses 3 selections and includes singles. The Yankee needs at least 2 winners for any return; the Patent only needs 1.
Can I bet a Patent each-way?
Yes. Each-way doubles your stake to 14 bets total (7 win + 7 place). Place legs settle at the win odds reduced by the bookmaker's place fraction, commonly 1/4 or 1/5.
Can I bet a Patent on football or other sports?
Yes. Patents work on any sport with discrete outcomes. They are most popular on UK and Irish racing because of the each-way structure, but football match-winner Patents are common at Bet365 and Paddy Power.
Do Patents have bookmaker bonuses?
No. The Lucky-family double-odds-on-single-winner and all-winners percentage bonuses do not apply to Patents. The calculator reflects the raw 7-bet sum.
Are Patents profitable long term?
Only when every selection has positive expected value. A Patent at 3 even-money selections breaks even on 2 of 3 winners; below that strike rate, the structure compounds the bookmaker's margin.
What unit stake should I use?
Choose a unit you would risk 7 times. A 1 unit Patent costs 7 units total. Disciplined bettors keep Patent exposure under 1 percent of bankroll for routine bets and only scale up when they have high-confidence picks.
Pro Tip: A Patent Is Just a Trixie Plus Singles
If your edge is in the doubles and treble rather than the singles, a Trixie costs less for the same upside. Use our EV Calculator to compare per-leg expected value before deciding between Patent, Trixie, or three straight singles.
