Law360, New York (October 1, 2015, 9:07 PM ET) — A federal judge in Wisconsin sided with First Quality Baby Products LLC on Wednesday in the latest suit in a yearslong patent battle with Kimberly-Clark, invalidating a patent for the refastenable seams found on Kimberly-Clark’s Pull-Ups training pants, determining that the concept is obvious because a patent from the 1980s anticipated it.
U.S. District Judge William C. Griesbach granted defendant First Quality’s summary judgment motion that the asserted claims of Kimberly-Clark Worldwide Inc.’s U.S. Patent No. 8,747,379 are invalid because they are obvious and because the same court had previously invalidated a closely related patent held by Kimberly-Clark.

“We are pleased that the court found for First Quality on both collateral estoppel and obviousness,” said Kenneth P. George, an attorney representing the defendants, in a statement.
