The hidden text doesn't really help and you could burn yourself bad if you get flagged for spamming your company name with hidden text. That's what it will look like to a bot. If they scrape the page and just throw it up somewhere, the hidden text still doesn't necessarily do anything for you. You're assuming that the text is thrown up blind. The best ripped content is rewritten (manually, automated, or a combination) and that stuff will get caught and tossed anyway.
The best defense is a good offense. Just keep building more good pages and more good sites. We get ripped all the time; great articles. If in USA, not too much trouble. We can usually identify and prove the theft and a C&D does the job right quick. Threaten DMCA and down it comes. Often rewritten and put back up, but is always second-rate to our original content. If outside the USA, not much leverage, but we have never seen any big negative hits from this. Wonder if Google accounts for international plagiarism and allows room for the fact that we don't have much leverage to get it down?
