A nearly two-year-old patent malpractice lawsuit filed against Kirkland & Ellis by former client Magnetek Inc. moved from state court to federal court last week.

The move was prompted by a November 2009 ruling by the Illinois Appellate Court that the state’s courts lack jurisdiction over malpractice suits tied to patent law issues. Kirkland & Ellis successfully moved to have Magnetek’s state court lawsuit dismissed in light of the appellate ruling.
