As he has done in the past, Dennis provides a very useful overview of the issues and perspectives on this important case.  Check out Microsoft v. AT&T: Transnational Patent Law At The Supreme Court.  I have not read the briefs yet, but the so-called “molecular conservation” argument seems to fit neatly with the statutory language.  Perhaps more to come once I find time to read the briefs, but for now check out Dennis’s coverage.
