Patent subject matter eligibility under Section 101 of the Patent Act has proven controversial for patents in the U.S. thanks in no small part to Supreme Court jurisprudence in cases such as Alice v. CLS Bank and Mayo v. Prometheus. In the latest development, the Court has declined to hear the American Axle case, which some see as presenting an exceptionally low bar for subject matter eligibility, leaving many observers despairing of any chance of restoring a decent patent system for makers of in vitro diagnostics and other items that are among the mainstays of the medical device industry.
In a decision that seems to have yet again roiled the patent subject matter eligibility question, the U.S. Court of Appeals for the Federal Circuit determined that a district court had erred in determining the 7,941,207 patent held by Cardionet LLC, of Conshohocken, Pa., is not eligible for patent protection.
The patent subject matter eligibility problem has rattled the world of diagnostics for several years, but the U.S. Senate has been silent about legislation in recent months. Patent attorney Michael Borella, of McDonnell Boehnen Hulbert & Berghoff LLP (MBHB), said he does not expect Congress to provide any legislative fix to the problem any time soon.
