What Is a Patent Bet?

A Patent is a full-cover system bet consisting of 7 bets on 3 selections:

  • 3 singles
  • 3 doubles
  • 1 treble

The key advantage over a Trixie is that a Patent pays out if just one selection wins because it includes singles. This makes it the safest 3-selection system bet available.

Patent structure:

Bet Type Selections Count
Single 1 A 1
Single 2 B 1
Single 3 C 1
Double 1 A + B 1
Double 2 A + C 1
Double 3 B + C 1
Treble A + B + C 1
Total 7 bets

Key characteristic: Just 1 winner needed for a return.

How the Patent Calculator Works

Enter your three selections and unit stake:

Input Description
Selection 1 Odds Odds for pick A
Selection 2 Odds Odds for pick B
Selection 3 Odds Odds for pick C
Unit Stake Stake per bet (total stake = unit × 7)

Patent Stake Calculation

Total Stake = Unit Stake × 7 bets

Example: $10 unit stake = $70 total stake

Patent vs Trixie: The Key Difference

Feature Patent Trixie
Number of bets 7 4
Includes singles Yes (3) No
Total stake ($10 unit) $70 $40
Minimum winners needed 1 2
Return if 1/3 wins Yes (reduced loss) No
Return if 2/3 win Yes Yes
Return if 3/3 win Highest Lower

Same Selections Compared

Selections: 4.00, 5.00, 6.00 (decimal odds)

Outcome Patent ($35 stake) Trixie ($20 stake)
All 3 win $1,045 $740
2 win (A+B) $145 $100
1 wins (A only) $20 (-$15 loss) $0 (-$20 loss)
None win $0 (-$35 loss) $0 (-$20 loss)

The trade-off: Patent costs more but provides singles coverage.

When to Use a Patent Bet

Ideal Situations

  1. Longer odds selections - The singles provide meaningful returns when one wins at good odds

  2. Horse racing - Unpredictable results make the safety net valuable

  3. Uncertain events - When you’re not confident all will win

  4. Building bankroll - Frequent small returns from singles

When to Avoid Patents

  1. Short odds favorites - Singles on favorites don’t return enough to justify the extra stake

  2. Budget constraints - 7× the stake of a treble is significant

  3. High confidence in all 3 - A treble or Trixie is more efficient

Patent Odds Analysis

Minimum Odds for Profit

For a Patent to be profitable when only one selection wins, that selection must return more than the total stake.

With $5 unit ($35 total stake), minimum odds for single winner profit:

Return Needed Odds Required
$35 (break even) 7.00
$40 ($5 profit) 8.00
$50 ($15 profit) 10.00

Key insight: Patents work best with selections at 7.00+ (6/1+) odds.

Why Odds Matter

Selection Odds Single Return ($5) 1 Winner Result
2.00 $10 -$25 loss
3.00 $15 -$20 loss
5.00 $25 -$10 loss
7.00 $35 Break even
10.00 $50 +$15 profit

Patent vs Lucky 15

The Lucky 15 is similar but with 4 selections:

Feature Patent Lucky 15
Selections 3 4
Total bets 7 15
Stake ($10 unit) $70 $150
Includes singles Yes Yes
Bonus features No Often yes

Lucky 15s typically include consolation bonuses (double odds for 1 winner, bonus for all 4 winners).

Real-World Patent Example

Saturday Horse Racing Meeting

Selection Race Odds
Golden Star 2:00 Ascot 5/1 (6.00)
Silver Flash 3:15 Ascot 7/1 (8.00)
Bronze Medal 4:30 Ascot 4/1 (5.00)

$2 unit stake = $14 total

Possible Outcomes

All three win:

  • Singles: $12 + $16 + $10 = $38
  • Doubles: $96 + $60 + $80 = $236
  • Treble: $480
  • Total: $754 (Profit: $740)

Golden Star and Silver Flash win, Bronze Medal loses:

  • Singles: $12 + $16 = $28
  • Double: $96
  • Total: $124 (Profit: $110)

Only Golden Star wins:

  • Single: $12
  • Total: $12 (Loss: -$2)

The 6.00 odds on Golden Star nearly breaks even with a single winner.

Patent Betting Strategy

The Break-Even Strategy

Choose selections where the average odds are around 7.00 (6/1). This means:

  • 1 winner: roughly breaks even
  • 2 winners: solid profit
  • 3 winners: excellent return

Diversify Your Selections

Don’t put all selections in the same race meeting or sport. Spread risk:

  • Selection A: 2:30 Ascot
  • Selection B: 3:00 Newmarket
  • Selection C: 3:30 Cheltenham

Each Way Patents

An each way Patent is 14 bets (7 win + 7 place). This provides even more coverage:

  • Win bets pay if selections win
  • Place bets pay if selections place (usually top 3-4)

Warning: Each way doubles your stake to $70 with a $5 unit.

Rule 4 in Patent Bets

Rule 4 deductions apply to each bet individually.

Example: Selection B has a 20% Rule 4 deduction

Bet Rule 4 Applied?
Single A No
Single B Yes
Single C No
Double A+B Yes (on B’s portion)
Double A+C No
Double B+C Yes (on B’s portion)
Treble Yes (on B’s portion)

Our calculator handles Rule 4 automatically for each selection.

Frequently Asked Questions

How many winners do I need for a Patent to pay out?

Just 1 winner is enough for a return, though you may not recover your full stake unless the odds are good.

What’s the difference between a Patent and a Trixie?

A Patent includes 3 singles; a Trixie doesn’t. This means a Patent pays on 1 winner, while a Trixie needs 2.

Is a Patent worth it for short odds favorites?

Generally no. The singles don’t return enough to justify the extra stake. Patents work better with odds of 5.00+ (4/1+).

Can I do an each way Patent?

Yes. An each way Patent is 14 bets (7 win + 7 place), costing double the stake.

What happens if one selection is a non-runner?

Bets including that selection are reduced. Singles become void (stake returned), doubles become singles, and the treble becomes a double.

Is a Patent the same as a full cover bet?

Yes, a Patent is the 3-selection full cover bet with singles. Without singles, it’s called a Trixie.
