This is an illustration of a method described elsewhere on this forum by COD. This method works with simple patterns or more complex patterns, consisting of many paths into a group.
You can also use classic boolean ops for simple patterns. Some more thoughts :
Notice that pattern > pattern to object can send the pattern tile far from it's original location. Use 3 key in numpad to zoom on selected object to find it.
Also notice that if the pattern filled shape has no stroke color defined, it will become invisible : give it a stroke color or use outline display mode.
In the path > intersection operation, the result inherits the style of the lowest object : in this example, orginally the circle had no stroke color, a pattern filed that is removed by the pattern to object process : on path > intersection, the result is invisible in normal display mode (no stroke, no fill).
Some hints to preserve the exact postion of pattern.
To avoid moving a pattern gone far far away after pattern > pattern to object, simply cut / paste it.
Notice that, in this example, the color of the svg pattern of circle, initially green, turns "black" after doing pattern > pattern to object : actually, it turns to unset : when designing svg patterns, all paths with unset fills, once turned into pattern, can have their fill color set using fill and stroke panel.

This tech has really improved in v1.4.x.
I would use Path>Object To Path instead of the LPE drop down menu item "Flatten". It could lock up Inkscape.
