Air Measurement v. Akin Gump is another reminder that there are alternative jurisdictional bases in Federal district court aside from diversity jurisdictino. Here, a legal malpractice case over representation in a patent law case allowed the matter to be brought in Federal District Court. Patent law resides exclusively [for all important aspects] in Federal law, and a legal malpractice case which arose from a claim of mishandling of a patent application will be sufficiently close to federal question for the court to allow a legal malpractice case to be litigated in Federal District Court.
