Honestly, I (by whom I mean my friend who did much of the hunting for me) had better luck finding a lawyer by specialization, and then by asking about English service second.
So, if you have an intellectual property case, find intellectual property lawyers, and then see what the firms offer in terms of English support.
I like my lawyer so far, but we’re just getting started. He writes English well.
Through forumosa some time ago, i found mine who specializes on Intellectual Property but I am sure h could have with general questions or direct you to other ones. Very nice person indeed.
