The Akzidenz-Grotesk typeface which is referred to in this article was first released in 1898, meaning that any patent or copyright claims on the original designs will have well and truly expired by now. However, specific digitisations of typefaces are subject to copyright individually, which is what allows such companies to charge royalties for their use. Whilst I couldn't find any truly free and open digitisations of Akzidenz-Grotesk, Berthold do seem to have a 'personal use only' licence which may be sufficient for a personal website. A passable substitute for Akzidenz-Grotesk (and a very nice free typeface in its own right) is Liberation Sans, freely available under the SIL Open Font License 1.1.
