What Is in a Patent
| Bet type | Number | Needs |
|---|---|---|
| Singles | 3 | 1 winner |
| Doubles | 3 | 2 winners |
| Treble | 1 | 3 winners |
| Total | 7 | 1 winner for a return |
At ₦100 per bet a Patent costs ₦700. With odds of 1.80, 2.10 and 2.40, three winners return about ₦2,851. If the third selection loses, the two singles and one double still return about ₦768, a small profit of ₦68. With one winner you get only that single back.
Patent vs Trixie
A Trixie is the same bet without the singles: four bets (three doubles and the treble). It costs less but needs two winners for any return. The Patent costs more and pays something with one winner, which suits picks at longer odds.
Placing a Patent
Add three selections to your betslip and choose all the system options for three (1/3, 2/3 and 3/3). The betslip should show seven bets. Some bookmakers list the Patent by name; others only offer the system options.
A Patent is the smallest full-cover bet, which makes it a good way to try system bets before moving up to a Lucky 15.
