China's accession into the World Trade Organization started four years ago. With this commitment to regulatory and economic restructuring, China has indeed been a country of economic opportunity for multinational corporations.

In theory, WTO accession means that WTO members can enjoy IP protections. In China, secure those patent protections carefully. Dot the i's, cross those t's and ‘watch your language.’ Also, anticipate litigation.

According to attorneys A. Jason Mirabito and Carol Peters, in a March 2005 article published in Chip Scale Review:

-- In the past there was little enforcement of IP in China. However, in 2002, Chinese courts litigated more than 6,000 civil cases involving IP issues. About 2,000 cases involved patent suits. The rest were trademark and copyright actions.

--Japan is the leading filer of patent applications in China, followed by the United States, Germany and South Korea, in that order. On the other hand, the United States is the largest filer of trademark applications, followed by the Japanese.

--Japanese companies have been the most litigious companies in China, filing a large number of trademark infringement and design infringement suits against Chinese companies, largely in the automotive industry.

Those 2002 statistics pale compared to recent figures, reported by the International Herald Tribune: In 2005, "Chinese courts dealt with 12,205 civil intellectual property cases, an increase of 32 percent from 2003 and a few dozen two decades ago."

Consider one recent case, which demonstrates that China's legal savvy is climbing with its growing stake in US markets and the global economy. The case also demonstrates the role of US courts in patent and IP protection, along with the perseverant or 'energized' stance required by US companies threatened by counterfeit goods or the prospect of piracy.

Energizer & Eveready vs. Just about Everybody

The dispute started in the spring of 2003, when Energizer Holdings, a US company, and its subsidiary Eveready filed a lawsuit with the International Trade Commission (ITC). The complaint addressed a signature product, a long-lasting battery design—affecting in particular a line of zero mercury-added alkaline batteries that Energizer has held a patent on for three decades. Also mentioned in the suit are games, toys, and other products manufactured with batteries whose designs are protected.

Energizer asked the ITC to issue a cease-and-desist order and to ban US imports of these products, claiming the batteries exported to the United States by the 26 manufacturers, affiliates or distributors named in the suit had infringed on Energizer's US patent. Among the multiple respondents named in the complaint, nine were Chinese manufacturers, including Fujian Nanping Nanfu. Nanfu Battery is one of China’s largest alkaline battery manufacturers and suppliers. Energizer requested the ITC investigation under Section 337 of the US Tariff Act.

At the time of the original filing, China was considered the world's largest manufacturer and exporter of this specific battery with an estimated 75-80 percent of its goods being exported to overseas markets. According to a China press report, "Chinese batteries usually cost between a 10th and a third less than US-made ones, making them very popular in overseas markets."

The ITC handed down a preliminary ruling in 2004, deciding that nine manufacturers from the Chinese mainland and Hong Kong infringed upon Energizer's patent, and recommended banning imports of the batteries. But four months later, the ITC closed its investigation, and ruled that Energizer's patent was invalid because it was …"indefinite as a matter of law…." Or, in the legalese: "The Commission held that Eveready's "proffer of alternative constructions of 'said zinc anode' was an admission of indefiniteness."

In plain terms, the main patent claim, or its language, was incorrectly written. Attorneys Mirabito and Peters reported that the Commission determined "there was no infringement of the Energizer Holdings patents, and the continued importation of Chinese batteries was permitted."

It Just Keeps on Going and Going…

True to the brand as "the battery that never quits," Energizer kept on "going and going," and appealed the ITC's final decision to the U.S. Court of Appeals for the Federal Circuit. In the suit, Energizer named the ITC as defendants. Energizer's main contention was that the issue regarding language was not substantial enough to invalidate the patent.

The Court's January 25, 2006 ruling, and a follow-up March 20 mandate reversed the earlier ITC opinion, finding that the ITC erred and the patent draft was written correctly enough.

"In that regard, we conclude that 'anode gel' is by implication the antecedent basis for 'said zinc anode.' The Commission's holding of invalidity on the ground of indefiniteness is r
