FAQ
Frequently asked questions
What is a Patent bet?
A Patent is a UK system bet on 3 selections made up of 7 bets: 3 singles, 3 doubles, 1 trebles. Because it includes singles, one winner is enough to get a return.
How much does a £1 Patent cost?
7 bets at £1 each cost £7.00. Each-way doubles the number of bets to 14, so a £1 each-way Patent costs £14.00.
What does a £1 Patent pay if every selection wins at evens?
£26.00 in total — a profit of £19.00 on the £7.00 stake.
What if one selection loses?
Only the bets containing that selection lose. With the example odds on this page (5/1, 3/1, 2/1) and the last selection losing, a £1 Patent still returns £34.00.
Are bookmaker bonuses included?
No. Some bookmakers add bonuses or consolations to Patent bets (for example extra odds when only one selection wins). Those terms vary, so we show the standard settlement only.
