A Patent consists of 7 bets on 3 selections:

Frequently Asked Questions

What's a Patent bet?

A Patent is a 7-bet system on 3 selections: 3 singles, 3 doubles, and 1 treble. Since singles are included, even one winner guarantees you a return.

How is a Patent different from a Trixie?

A Patent adds 3 singles that a Trixie skips, making it 7 bets rather than 4. The upside is that one winner guarantees a return; the downside is a bigger total stake.

Is a Patent a good bet?

Patents give you solid coverage because a single winner returns something. They shine when your selections carry higher odds, since the singles can cover your total stake even with just one winner.
