Plastic Omnium v. Donghee America

Litigation Graphics

CLIENT: A2L Consulting
SCOPE: PowerPoint Presentation for Trial
Omnium sued Donghee, asserting infringement of eight patents, including the 921 and 812 patents, which generally relate to manufacturing plastic fuel tanks formed by blow molding. The fuel tanks are formed in a way that allows accessory components to be installed inside the fuel tank without cutting holes in the tank wall, which could compromise the structural integrity of the wall. The parties disputed the meaning of the term “parison” (a rounded mass of molten glass formed by rolling the substance immediately after the removal from a furnace). Donghee argued that it should be given its plain and ordinary meaning of “hollow plastic tube exiting the die of an extrusion head.” Omnium argued that the patentee had acted as its own lexicographer and that the patents do not use the term in its conventional, ordinary meaning.​​​​​​​
