In the U.S., an inventor has one year from the earliest sale, offer for sale, public use, or publication of an invention to file a patent application. After one year, it is no longer possible to obtain a valid U.S. patent for whatever what published. A requirement of obtaining a patent is being an original inventor. Other countries are more strict and require that a patent application be filed before any publication takes place, though there are some exceptions. There are some questions open as to exactly what was published relative to what was invented so your friend should seek competent counsel as soon as possible.
