Jack Barufka, a partner and leader of Pillsbury’s intellectual property group in Northern Virginia, is quoted on a ruling by the Federal Circuit Court, which allowed Congress to include a provision in the America Invents Act that invalidates most pending false-patent-marking suits.

Specifically, the court affirmed the dismissal of a suit against musical accessories maker Dunlop Manufacturing Inc., filed by a California patent attorney, ruling that by foreclosing lawsuits that had already been filed, Congress did not violate the due process clause of the Constitution.

"This ruling puts the final nail in the coffin of the old cases, which were largely burdensome to legitimate companies," Barufka said. "They were being hit with cases left and right, almost daily, by individuals trying to take advantage of poorly drafted law."
