I agree that the current DMCA take-down system is efficient, but there are good reasons for it being the way that it is. Take a moment to think about it before bashing everything to do with 'law', and come up with some plausible alternatives. At the rate that new content is pirated, going through previously existing legal procedures for each case of infringement on the internet would be a ridiculous waste of time and money not only for the copyright holders, but for online service providers (OSPs) like Google or Twitter. You can literally find several links to copyrighted material online within minutes after a show airs or even before a movie opens in your area. Are you honestly telling me not only that you would be completely OK with companies wasting that much more time and money, but that you'd be OK with paying more for each of these products to cover their costs?
In the DMCA take-down process, there actually are provisions which say that the claimant is liable for what they indicated in the notice, under penalty of perjury if it is found to be false [1]. And the counter-notice to reinstate your page's listing is just as simple as the initial take-down notice. In this case, as many have already pointed out, even though it is "Office 2010" that is trademarked - having a piece of software or torrent named "Open Office 2010" can in fact still infringe. This is the same reason you would see Burger King going after McDonalds if they named a new sandwich the "Open Whopper". You can't just add a word to the front of a trademark and have that magically be OK, at least based on my current understanding of how trademarks are supposed to work.
Beyond all that, though, individuals can have a copyright or trademark just like businesses or corporations. If you have one, you can protect it with the same DMCA take-down notices that they use.
