SHEBOYGAN FALLS, WI, April 27, 2016-

Earlier this month Curt G. Joa, Inc. filed an inter partes review proceeding against Fameccanica Data, SpA to invalidate a patent owned by Fameccanica. The case, filed in the United States Patent and Trademark Office, Patent Trial and Appeal Board asserts invalidity of United States Patent No. 6,994,761, entitled “Disposable Absorbent Garment such as a diaper or training pants and a process of making the same.” This proceeding follows another attack on Fameccanica’s European Patent (UK) no 1355604 with the same title.

In its petition, Joa alleges that other patents prior in time to United States Patent No. 6,994,761 disclose the invention claimed in Fameccanica’s patent: a breathable, stretchable layer assembly including an inner material layer, an outer material layer and a stretchable material layer disposed there between and including vent sites which are formed by ultrasonic bonding of the inner and outer material layers through the stretchable material layer.
