Formula

A Patent consists of 7 bets on 3 selections:

Just one winner guarantees a return from the singles.

Frequently Asked Questions

Define a Patent bet.

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

Patent versus Trixie?

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

Is a Patent a sound bet?

Patents give solid coverage since one winner returns something. They perform best with higher-odds selections, where the singles returns can recover the total stake off just one winner.
