For IP law, I'd suggest:
"Intellectual Property Law," by Lionel Bentley and Brad Sherman. That's a pretty ace book and a good starting point for most areas of IP. Well, it helped me get a 2.1 in it, so... yeah. I'd get a second one as well so you can compare different points of view on a question.
Also, the IP Kitten blog, done by my former tutor in trade mark law,
http://ipkitten.blogspot.com/ is worth a look for keeping up with new developments.
For Trusts and Equity, which is a subject I really couldn't abide but kinda had to do, the following are what I used:
J. C. Penner, "The Law of Trusts," can't remember the publisher. This is a smallish book which gives the essential on it, but which I never really cared for.
David Hayton and Charles Mitchell, "The Law of Trusts and Equitable Remedies," Butterworths? This is big and lumpen but it has all the appropriate excerpts from most of the cases in it.
I wish I could be more help, but all my English law books are in my room in High Wycombe whereas I'm shacked to the trilithon of the maitrîse intégrée here in Paris. Gnagh, I hate French law.
