Kaneka Files ITC Complaint in the Field of Coenzyme Q10 against its Rivals in China, Japan and the United States

June 20, 2011
Kaneka Corporation (headquarters: Osaka, Japan; President: Mr. Kimikazu Sugawara)
announced that on June 17, 2011, it filed a complaint with the U.S. International Trade
Commission (ITC) against Zhejiang Medicine Co. Ltd., ZMC-USA, LLC, Xiamen Kingdomway
Group Company, Pacific Rainbow International, Inc, Mitsubishi Gas Chemical Company, Inc.,
Maypro Industries, Inc., and Shenzou Biology & Technology Co., Ltd. (collectively “Defendants”),
who directly and/or indirectly infringe Kaneka’s U.S. Patent No. 7,910,340 (the “Kaneka
Patent”). The complaint alleges that Defendants have engaged in unfair trade practices by the
importation and sale of Coenzyme Q10 products that infringe the Kaneka Patent.
The ITC is a quasi-judicial Federal agency that offers an alternative, fast-tracked forum for
foreign and domestic owners of U.S. intellectual property rights to seek to block infringing
products from the U.S. market. In particular, 19 USC §1337 authorizes the ITC to address
claims of patent infringement by imported goods and unfair competition related to imported
products. The ITC operates with unique rules and procedures that typically result in
considerably faster determinations and can provide immediate consequences for importers,
manufactures and sellers of infringing products.

Kaneka is requesting that the ITC commence an investigation into Defendant’s unauthorized
use of the Kaneka Patent and, among other things, issue an Exclusion Order barring the
importation of infringing products, prohibiting further sales of infringing products that have
already been imported, and halting the marketing, advertising, demonstration and warehousing
of inventory for distribution and use of such imported products in the United States.

Kaneka expects that once the ITC investigation is instituted, a trial will be concluded by May
2012. Kaneka is also currently investigating the use of these infringing Coenzyme Q10
products in consumer products such as dietary supplements, cosmetics, oral care products, and
The ITC action follows Kaneka’s filing of a patent infringement suit on March 22, 2011 against
Defendants in the U.S. District Court for the Central District of California for infringement of
the Kaneka Patent. In the District Court action, Kaneka is seeking an injunction prohibiting
the manufacture, importation, distribution, sale and use of infringing products in the U.S., as
well as monetary damages.
Oxidized coenzyme Q10 (Ubiquinone) is also known by its trade name Kaneka Q10™. Kaneka
has been the recognized industry leader in coenzyme Q10 for the past 30 years, and is the largest manufacturer of coenzyme Q10 in the world.

The ITC action continues Kaneka’s worldwide enforcement policy for the protection of its
intellectual property rights. “Kaneka has been the leading developer of many innovative and
cutting edge improvements in the production and quality of coenzyme Q10,” said Mr. Yoshimi
Uchida, General Manager of QOL Division at Kaneka. He added: “Kaneka will vigorously
defend these rights and will not hesitate to initiate court proceedings to protect its intellectual
property.” Mr. Uchida emphasized that “Kaneka’s goal is to protect the results of its research
and development and to avoid the unauthorized use of its innovations.”
