አማርኛ A Patent covers three selections with all seven possible bets: 3 singles + 3 doubles + 1 treble. It is a Trixie plus singles, so even one winning leg returns something.
Seven units of stake buys full coverage, which suits confident picks at bigger prices — the singles carry real weight at 3.00+. At short odds the singles return pennies and the structure becomes expensive insurance on insurance.
Worked example
£1 Patent (£7) on three picks at 3.50. One winner: its single returns £3.50 — half the outlay back. Two: 2 singles (£7) + 1 double (£12.25) = £19.25. All three: £10.50 + £36.75 + £42.88 ≈ £90. Compare the £7 treble alone: £0, £0, £150 — the Patent trades jackpot for floor.
