A district court recently granted a Rule 12(b)(6) dismissal of patent claims directed to intermittent fault detection (IFD) technology for electrical systems in aircrafts, deciding that the asserted claims are patent ineligible subject matter under 35 U.S.C. § 101. The court found that the claims fail to recite any specific technological improvements over the prior art, because the alleged innovations were described in the specification but not recited in the claims.
