The US Supreme Court heard oral arguments in the case of KSR International v. Teleflex, in which the limits of combination patents and so-called obvious patents are being considered. According to several wire reports, KSR argued that its design for adjustable vehicle accelerator pedals does not violate a patent held by Teleflex for a similar gizmo, because Teleflex did not legitimately invent anything when it combined two existing technologies in an obvious way, and does not, therefore, deserve the patent.
