Well put Oliver but a Trademark does evolve over time in both design, content and words.

A trademark and a patent are two entirely different animals.

A trademark can evolve in Design, is the logo design, the word, the label and device of Coca-Cola the same it was way back when it started. Probably not. That's a trademark.

Is the Coca-Cola we drink today the same as it was in the beginning? That would be more patent related.

Is the taste of Coca-Cola the same everywhere, not sure it is identical everywhere but very similar indeed. - That would be more patent related.

A Trademark does evolve to meet market conditions, a Trademark is simply a representation or words to identify a particular product and associate it with a company and a level of quality be it good or bad.

So in essence, Page Rank can change behind the scenes as much as Google likes, it's their patent. The trademark, the physical representation of Pagerank, be it the green bar or the words will evolve when it become outdated or stale as do all Trademarks to appeal to people's eyes!
