The Modern Law of Patents (2nd Edition) by Ashley Roughton among others.
The Modern Law of Patents is now in its second edition. It is seen as a major publication on the law of patents (both UK and European) in a practitioner context. The book has been well reviewed and received. It was recently reviewed by Professor Christopher Wadlow for the Journal of Intellectual Law and Practice (OUP, February 2011 edition) in the following terms:-
“Taken as a whole, the Modern Law of Patents lives up to its name. It reads well, and consistently impresses with its grasp of detail, which is matched with a sense for structure. It is impossible on short acquaintance to say how accurate it is, as that must await the judgment of practical experience, but it promises well. It states its own case for a place on the practitioner's bookshelf, but its relatively compact dimensions would make it a useful companion at court, where the extensive primary materials would come into their own, or on one's travels.”
