Amkor originally filed a patent infringement complaint against Carsem with the International Trade Commission (ITC). The ITC judge ruled that Carsem had infringed Amkor’s patents related to its MicroLeadFrame package technology. However, the November 2004 decision did not find that Carsem had committed a statutory violation of the Tariff Act, which would have banned the company from importing the infringing parts into the U.S.

The Focal Point’s Role

The Focal Point assisted IP lawyers at Sidley Austin Brown & Wood throughout the litigations with animations and graphics that covered a wide range of needs. A tutorial was created for an expert witness to brief the court on the specifics of this semiconductor technology. Numerous animations and graphics were produced to fight Carsem’s claims of invalidity towards the Amkor patents that were being asserted. PowerPoint presentations were created to show that Amkor’s products embodied the claims within its patents. And finally, presentations were created that stepped, claim-by-claim, through each Amkor patent to show that Carsem’s chip packaging technology did indeed infringe on Amkor’s patented QFN Integrated Circuit technology.


The ITC ruled in favor of The Focal Point’s client, Amkor Technology, finding that rival packaging supplier Carsem violated Section 337 of the Tariff Act in the importation and sale of devices that infringe Amkor’s MicroLeadFrame patent.
