This is beginning to go in circles but that's unsurprising; such discussions on forums are almost always discursive and repetitive. And in reaching any conclusions in this case we're handicapped (or liberated?) by a profound lack of knowledge. As far as I know no one here is an IP attorney. It's a highly specialized branch of the law, of course, and therefore offers a nice example of what you don't know can most definitely hurt you. Over the decades I've hired numerous law firms in almost all areas of the law. I've retained patent lawyers in particular many times and been involved in IP litigation; but that no more makes me an IP expert than the fact that I've been operated on makes me a surgeon. For that matter my wife is an attorney and we've been married since the 1980s; oddly enough that doesn't make me a lawyer either. I'm pretty sure it takes more than propinquity.
