I kindly disagree. I have personally seen language regarding patent coverage in these situations and previous posts are correct in that they can represent both... but if I recall correctly, they typically give the client the option for seeking representation elsewhere. I also believe that those attorneys that are directly involved in representing "you" in the case are conflicted out and don't typically have "contact" with the other side in the same firm. This is through discussions with an acquaintance of mine who is a patent attorney at a very well known firm....
