Attorney-client privilege and ethics: can you help?

Jeremy has learned that there is a great deal of trademark-specific (or at least IP-specific) law and practice in this area in the United States, but he has little familiarity with it in other jurisdictions and would welcome any guidance. So, if you are from outside the US and
please email Jeremy here, heading your email 'Privilege'. He will be delighted to hear from you.(i) are interested in this subject and would be prepared to answer his questions, or (ii) are an academic who is currently doing research in this area, or is seriously contemplating doing so, or
(iii) can suggest any useful reading materials, case law etc,
