## What is a Patent bet

Patent bets fall in to the category of “Full cover bet with singles”. It consists of 3 selections, combined into 7 separate bets. One treble, 3 doubles and being a full cover bet with singles you also have 3 single bets. Patents are the equivalent of a Trixie but with singles.

## Patent calculations

Being the smallest of full cover bets with singles a Patent is also the easiest to calculate. In fact as it only contains 4 accumulators and 3 singles it isn’t even that hard to work out by calculating the 7 bets separately. It is however beneficial to learn the method of calculating a full cover bet with singles as it will help whenever you need to calculate the larger bets such as lucky 15, lucky 31 and the massive 6 selection lucky 63.

The longer more tedious way of working out full cover bets with singles is to calculate each bet within the combination bet individually and then add them together. If you were to do that with a Patent bet the maths would be

ABC + AB + AC + BC + A + B + C

Here each letter represents a different selection you are betting on, so for example A might be Manchester United, B Chelsea and C Arsenal. And if you can remember your days of maths at school when you put variables together, such as AB, it is the equivalent as writing A multiplied by B.

Now if you have a look at this basic equation and the multiple out the brackets you will see how the final Patent settlement bet equation is derived. This is also the method used for all the bigger full cover with single bets.

(A + 1)(B + 1)(C + 1) = ABC + AB + AC + BC + A + B + C + 1

As you can see the equation that is almost the same as that for calculating the Patent bet the long way, except for the +1 on the end. As this is now known all that needs to be done for this basic equation to be used for the settlement of Patent bets is to subtract 1 from it.

(A + 1)(B + 1)(C + 1) – 1

The final answer will also have to be multiplied by the unit betting stake of the bet. The unit stake is what is placed on each individual bet and not the whole stake of the bet. A £2 Patent will require you to risk £14 in total as it has seven different bets (2 x 7 = 14).

## Example of how our Patent calculator works

If you are still confused after seeing the calculations section this simple example will clear everything up. Sometimes you will need to do some more complicated calculations due to Rule 4 deductions or Dead heat calculations. This simple example assumes you know each of the selections final odds, and remember if you ever have trouble you can always use our calculator as a fall back or get in contact with us and we’ll do our best to help you understand how the calculations work.

In this example all three betting selections win, you have bet a unit stake of £1 and the odds are 2.5, 3 and 5. As you are already aware each variable in the equation represents one of your selections, so just replace each variable with one of the odds.

(2.5 + 1)(3 + 1)(5 + 1) – 1

If you can’t work this out in your head you can always use the calculator on your phone or any hand held calculator.

3.5 x 4 x 6 – 1 = 83

The total return on this bet would be £83. This is the amount the bookie will give you. But remember you have already given the bookie £7 for this bet, £1 unit stake multiplied by the seven different accumulators (a single can be seen as an accumulator with one selection). Therefore the total profit on this bet is £76.
