When a Patent makes sense — honestly

Every bet inside a Patent carries the bookmaker's margin, and combining selections multiplies that margin just as it multiplies the odds. A system bet never improves your expected value over the same stakes placed as singles — what it changes is the shape of the outcomes: the singles soften bad days, while the bigger combinations carry the upside. That is a variance choice, not an edge.

The honest way to use one: pick selections that are each positive value on their own (our screener ranks the board by exactly that), keep the unit stake small enough that 7 bets fit your bankroll rules, and check every price before placing — a leg that drifted past fair value weakens every combination it sits in, not just its own single.

Patent FAQ

What is a Patent bet?+

A system bet on 3 selections made of 3 singles, 3 doubles, 1 trebles — 7 bets in total, each carrying its own stake. 3 selections: 3 singles, 3 doubles and 1 treble — 7 bets. One winner already returns something.

How much does a Patent cost?+

Your unit stake times 7. At 1 unit per bet the full slip costs 7 units — the calculator shows the exact outlay as you type.

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

One. The singles mean a lone winner already returns something, though usually less than the total outlay — the calculator shows the exact figure for your odds.

What happens to void selections?+

A void (postponed match, non-runner) is not a loss: every combination containing it is settled at odds of 1.00 for that leg, so doubles become effective singles and so on. Mark a selection Void in the calculator to see the effect.
