Match the last parenthesis group

I have a string that looks like this

Some text (group1) some more text (group2) some more text (groupN)

Can somebody help me to write a regular expression that matches groupN? That group is always at the end of the text.

I tried this expression 

\(.+\)

But, it matches from the opening parenthesis of group1 to the closing parenthesis of groupN. I only need to match groupN.

Thanks for your help.

If the final parenthesis might have text appearing after it, as in:

some text (first) and (last) more text

You can use a lookahead to check there are no more parenthesis in the string after the match:

\([^)]*\)(?=[^(]*$)

If not then just match a $ as falsetru correctly suggests.

Use following regular expression. It matches only at the end of the input string. ($ matches the end of the input string or end of line according to regular expression engines.)

\([^()]+\)$

Javascript example:

> 'Some text (group1) some more text (group2) some more text (groupN)'.match(/\([^()]+\)$/)
["(groupN)"]
