Are you 100% sure the content is identical? We often look at others' sites and think they're same same, while they're not. Maybe Google found each site is actually different and that's why it displays them.
I, too, have a competitor who have spammed all our local playground with his main website's clones, but I have never thought of reporting him. That's how losers act. And it won't work, either without getting some decent backlinks.
I noticed network guys work on similar backlink profile or cross-link their sites. Quite often, a couple very good links can help. Perhaps you can try a press release to make it to the news sites and maybe a blogger or two write about you.
