MED v. Impresa - New design patent case over "products used to treat chronic thumb sucking" https://design-law.tumblr.com/post/724630206094114816/does-this-thumb-sucking-prevention-device-infringe

This raises interesting issues about the use of interior broken lines. What, exactly, do they mean there? This matters not just because of the differently-shaped holes on the thumb-covering portion but also because the accused product has a hole where the claimed design has a solid surface.
