Formula

A Patent consists of 7 bets on 3 selections:

  • 3 Doubles: AB, AC, BC
  • 1 Treble: ABC

Total Stake = 7 × Unit Stake

Just one winner guarantees a return from the singles.

Frequently Asked Questions

How is a Patent bet structured?

A Patent is a 7-bet system built on 3 selections: 3 singles, 3 doubles, and 1 treble. With the singles included, a single winner guarantees a return.

How does a Patent differ from a Trixie?

A Patent adds the 3 singles that a Trixie omits, making it 7 bets rather than 4. The upside is that one winner guarantees a return; the trade-off is a higher total stake.

Is a Patent worth placing?

Patents give solid coverage because one winner already returns something. They perform best when your selections carry higher odds, since the singles returns can recover the full stake off just one winner.
