Same as what was stated above, you can't do anything and nothing will happen, unless you plan to take it to court. Which only applies to countries (And in most cases, only applies in addition to, specific people/companies or special interest groups) that give a shit.

Example: Chinese company is caught stealing I.P. from a American company (small or big), neither government will take you serious and will laugh at you.

On another note, just for you personally, think about the cycle of Karma.
