If you find that a competitor of yours has copied your content then one of the avenues open to you is to notify Google of this.
You can do this by filing a DMCA notice directly with Google at: https://www.google.com/webmasters/tools/dmca-notice?pli=1&
Google takes these complaints very seriously and follows them up with strict actions which can result in your competitor's content being removed from Google's search results.
