Are there any templates or useful packages for writing a patent specification, such as the ones in this collection?
I know about these two. The first one looks good and was successful used by the author for his patent applications. The other one is quite old: it is packed as shell archive and for LaTeX2.09, but works well with a modern LaTeX2e. I can't tell you more about them. All my patent applications had to be written in MS Word.
