Korean OPC makers appeal

February 27, 2012

Korean Patent Court upholds validity of Canon drum gear patent and four OPC manufacturers go to appeal.

On 2 February 2012, the Patent Court of Korea released its decision to dismiss the petition by four Korean OPC manufacturers for the patent of Canon gear, which was raised by the four unnamed Korean OPC makers in July 2011.

On 23 February the four companies lodged an appeal against the court decision to Supreme Court Korea.

David Connett, Editor of The Recycler, commented: “It may take six months for the Supreme Court of Korea to issue their determination and, as readers might be aware, Park & OPC and Samsung lost a similar suit in November 2007.”
