Semiconductor Patent Litigation Part 2: Nationalism, Transparency and Rule of Law

“The 60-year-old Yin Zhiyi (Gerald Yin) resolutely gave up the US’s annual salary of one million dollars, broke through the layers of US government review, … He led a team of more than 30 people back to China. … At the age of 60, he returned with his brain and founded China AMEC.

He said: We have done a lot of things for foreigners. It is time to make contributions to the people of our own country. He not only returned alone, but also led a team of outstanding Chinese of more than 30 people. It can be said that everyone has their own high-end technology weapons. And this move by him immediately caused the U.S. security department(s) to block him…  All the process and design drawings were completely confiscated.”

In my last blog I noted how semiconductor chip 芯片-related patent cases have a relatively low level of success in China, and that there appear to be wide regional variations in success rates.  Today, I will look at some of the legal issues raised by the emergence of Fujian as a venue for litigating these cases.  We begin by looking at the saga of Advanced Micro-fabrication Equipment, Inc. (AMEC), a semiconductor equipment manufacturer based in Shanghai, of which Gerald Yin, the subject of the above article, is both chairman and CEO.

AMEC has been described by the U.S. government as China’s leading semiconductor equipment manufacturer.    It has also been involved in three high profile IP disputes with US companies since its establishment.  Gerald Yin was a long-timer in Silicon Valley, previously served as a Vice President of Applied materials before joining AMEC, and prior to Applied he was with Lam Research and Intel – a scenario not unlike other Silicon Valley tech employees.  According to an on-line bio, he holds a doctorate in Physical Chemistry from UCLA and is the inventor of 86 US patents and more than 250 foreign patents.  AMEC’s case against Veeco earlier this year appears bears many similarities to the facts noted in the media report of a preliminary injunction decision issued on July 3, 2018 in favor of UMC and Fujian Jinhua’s case against Micron, another American company, also in Fujian province.

AMEC’s Batting Average

The records regarding AMEC’s prior legal challenges are complex and scattered across multiple jurisdictions.  They include court cases, patent filings, patent oppositions and Customs actions. It is frankly beyond the scope of this blog to fully analyze the validity of each claim and counterclaim.  Overall AMEC appears to be enjoying a high win rate.

The reported legal saga begins when Applied Materials sued AMEC in California (2009) for misappropriation of trade secrets that related in part to confidential information he obtained while at that company which were also the subject of patent applications by him.  The case was dismissed in favor of AMEC on the basis that the contract regarding the inventions violated California law against enforceability of non-compete agreements, depriving Applied of any rights to inventions whether or not there had been a misappropriation of confidential information.  Also of note, in 2009, AMEC brought suit against Applied in Shanghai, under the anti-unfair competition law (AUCL), presumably for trade secrets, which was withdrawn on January 1, 2010.  Withdrawn cases permit the parties to refile later as no decision has been reached on the merits and may not be included in official case law databases.

Another case involved AMEC and Lam Research, another Silicon Valley company which was also Gerald Yin’s former employer.  This matter involved patent infringements and was litigated in Taiwan.  By 2012 Lam Research had exhausted its appeals and lost.

AMEC v Veeco

AMEC’s most recent dispute with Veeco, a New York-based competitor with a subsidiary in Shanghai, involved preliminary injunctions for patent infringement in the US against a supplier to AMEC and a preliminary injunction in China against Veeco, as well as Chinese Customs seizure of imported goods of Veeco that infringe Amec’s Chinese patent. Preliminary injunctions in patent cases have historically been quite rare in China.  For example, in 2013, Chinese courts granted 11 preliminary injunction requests out of 90,000 IP cases. According to press reports, the dispute between Veeco and AMEC ended with a global settlement.

The US action was commenced on April 12, 2017 in the Eastern District of New York against one of AMEC’s suppliers, SGL.  Limited discovery was conducted in July and October 2017.  The 76 page opinion of Judge Chen, dated November 2, 2017 and amended November 16, 2017, reviews the challenges to patent validity, the scope of infringement, extraterritorial issues and the balance of equities in issuing a preliminary injunction against SGL (the drawing above is excerpted from her opinion).  Chinese commentary suggests that Judge Chen did not have the benefit of the Chinese validity challenges based on on novelty or non-obviousness.  However, the issues, including an alleged pre-existing “hockey puck” design are discussed at length in Judge Chen’s opinion, and there appears to have been discovery, expert opinion and due process provided (see text at fn. 64 and references to “hockey puck”).

Note that on January 23, 2018, SIPO declared the counterpart patent(s) to those asserted in New York to be invalid.   Of particular concern in the NY litigation was the ‘769 patent, formerly owned by Emcore.  AMEC reportedly launched an invalidity challenge at the USPTO on December 8, 2017 against this patent.  A Chinese author’s description of the global patent challenges is found here.

The second significant decision involved a case initiated by AMEC against Veeco in July 2017. and the Fujian High Court granting an injunction on or about December 7, 2017 (see media reports). This case has not been released to the public.  I have therefore had to rely on various secondary sources of information in order to understand the circumstances of this case.

A Veeco press release states that “On December 7, 2017, without providing notice to Veeco and without hearing Veeco’s position on alleged infringement, the Fujian High Court issued a ruling, applicable in China, that requires Veeco Shanghai to stop importing, making, selling and  offering to sell Veeco EPIK 700 model MOCVD systems which contain the accused infringing synchronous movement engagement mechanism covered by AMEC utility model patent ZL 201220056049.5 and wafer carriers used as supplies for the EPIK 700 MOCVD system.” The circumstantial circumstances seem to support this position.  According to AMEC’s press release, the patent in suit was the subject of two invalidity challenges and was held valid by the Patent Reexamination Board on November 24, 2017.  This was the Friday of the US Thanksgiving holiday.   The patent in suit was a utility model patent, ZL201220056049.5.  Assuming that AMEC moved for a preliminary injunction on the following Monday, November 27, 2017, the injunction would have been issued approximately nine business days later, hardly time for a thorough consideration of infringement issues or the weighing of factors in a preliminary injunction.  The Chinese preliminary injunction case was different from the US case in many respects: notably the US decision was published, involved months of hearings and exchange of documents, and the decision was not issued on an ex parte basis.  I assume it would also be difficult for the Fujian High Court to issue as lengthy a decision as EDNY in light of the limited time it had before it rendered its decision, but we lack the benefit of a published decision in this matter.

AMEC v Veeco also shares other concerns with Chinese countersuits against overseas litigation.   Although this case was filed after Veeco filed its case in the United States, the court seemed intent on accelerating its decision making in order to undercut the effect of a US judgment.  As I have noted, this is typically done without any consideration of comity, and it is a common litigation tactic for a Chinese defendant to seek a quick decision from a court where it has a close relationship to undermine the effectiveness of an overseas litigation or 337 investigation.  It is hard to deny that the Fujian High Court is paying attention to timing when the Fujian High Court apparently drafted its non-public decision in less than two weeks.

There are some other similarities with Chinese anti-foreign suit litigation, including that often these cases also end up getting recognized as a “top 10” /guiding/leading cases  by local or national authorities and the authorities extol how they can help guide Chinese companies to break open foreign markets, thereby adding fuel to a techno-nationalist fire.

Another strategic point is that AMEC’s principle weapon was a Utility Model Patent (UMP), which lasts only 10 years.  The use of utility model patents or design patents to countersue in China is a well-established practice (Chint v Schneider; Chery v General Motors).  One reason may be that UMP’s do entail a lower threshold of inventiveness than an invention patent and for that reason may be harder to invalidate.  In a sense, AMEC’s “high tech” weapon was the lowest tech patent weapon in the toolbox.   For a utility model, the invention must possess “a substantive feature and indicates an advancement”.  An invention patent requires “a prominent substantive feature and indicates remarkable advancements” (Patent Law, Art. 22).  Nonetheless, as has been evident for 10 or more years, UMP’s can have remarkable litigation value and should be considered a part of every foreign company’s patent portfolio for both defensive and offensive purposes.

The Customs proceeding is also a bit of an outlier, and also lacks any publicly available record.  While Chinese Customs has the authority to seize goods on import, and to seize goods that infringe patents, such seizures are rare.   The seizure by AMEC was also listed as one of Shanghai’s “top 10” IP cases for 2017, and the listing made it clear that the case should serve as an example for other innovative Chinese companies.

There are other unusual aspects to this case.  For example, why would a Shanghainese company (AMEC) file a case in Fujian against another company (Veeco) that is also locally headquartered in Shanghai?  Furthermore, why did they choose a jurisdiction which hasn’t seen one reported patent case with the word “chip” (芯片) in it?

Transparency Woes

The AMEC case now joins a short list of not-so-distinguished cases involving foreigners, where the court has yet to publish or significantly delayed publishing the final decision, including Huawei v Interdigital (Shenzhen first instance decision) and Chint v Schneider (Wenzhou).   This lack of transparency is striking considering the great strides generally being made in publishing court decisions.   Publishing decisions and other forms of transparency (such as amicus briefs) help ensure fairness, improve the quality of decisions, prevent corruption, develop appropriate legal strategies, and insure consistency with other legal opinions, amongst other benefits (as also noted elsewhere on this blog).

There may also be other explanations for this lack of transparency. The case was settled and, as noted, often decisions are not published after a case is withdrawn.  In addition, the case involved a preliminary injunction and such cases are just rarely published.  In the not too distant past requests for a preliminary injunction were handled exclusively by the “case filing division” of the courts and thus were never formally docketed. However, courts throughout China have been moving to limit the case filing division’s lack of transparency, and applied less discretionary “case recordal” acceptance procedures.  Fujian is no exception.  Non-publication leaves one guessing as to motives.

Added Motives to Be Non-Transparent?

Semiconductor companies are entitled to know more about Chinese and Fujian judicial practices in semiconductor patent matters, and what factors weigh in granting the rare preliminary injunction.  The news of July 3, 2018 that  the Fuzhou Intermediate Court reached a decision involving Micron’s alleged infringement of semiconductor patents, and that this case has apparently been released to the plaintiffs but has not yet been provided to the defendant, underscores the need for transparency (See press reports of Jinhua, UMC and Micron).   Also of concern is that the decision, which reportedly has immediate (立即 ) effect, was released the day before a US national holiday, July 4.  Generally preliminary injunctions are not effective until served, but time is likely of the essence in responsing to this order.  See also TRIPS Agreement Art. 41.3 (“3.  Decisions on the merits of a case shall preferably be in writing and reasoned. They shall be made available at least to the parties to the proceeding without undue delay.”)

Another concern amongst the foreign business community, given the current trade climate, is whether China has begun using legal tools to retaliate against US companies in sectors targeted by “Made in China 2025”, including retaliation against efforts to use overseas litigation.   The Micron decision comes less than two weeks after a promise that Beijing would not seek retaliation against foreign companies operating in China.  China’s increasing involvement in the semiconductor sector was described by former U.S. Commerce Secretary Pritzker in September 2016 as “unprecedented” state-driven interference that “distorts the market” and “undermine[s] the innovation ecosystem.”

One hopes that industrial policy is not affecting the legal system, as right now we need less, not more, fuel on the trade war fires.   Appropriately containing disputes to fair and expert legal systems can be one effective way of reducing trade tensions.

I welcome any commentary, corrections and updates.

The opinions expressed herein are mine alone.  In my capacity as an academic at Berkeley and as a lawyer or consultant, I do receive support from and advise semiconductor companies as well as service providers from time to time.  These comments were drafted solely in my academic capacity and without clearance or review by any company or association.

A Data Download on Semiconductor Patent Litigation in China

Because of its strategic importance to both the United States and China, the IC sector is a useful example of how Chinese policies and plans may – or may not – be influencing the Chinese government in the protection of foreign-owned IP.

A useful starting point for evaluating the challenges in IC IP protection in China is the data collected from China’s court cases.  IP House has conducted a heretofore unpublished and useful study of all semiconductor-related patent disputes in its database, attached here (in Chinese).  The data shows that there have been 166 first instance civil patent infringements IP judgments with the word “chip” (芯片), and 86 second instance cases.    There have also been 142 first instance administrative decisions, typically involving validity matters, and ninety second instance decisions. 52.91% of the first instance cases involved invention patents, 10.31% involved utility model patents and 36.77% involved design patents.

Regarding civil cases, 39 were heard in Zhejiang, 35 in Guangdong, 27 in Beijing, 21 in Jiangsu and 11 in Shanghai.  Every other jurisdiction had fewer than five cases, and no cases were reported for Fujian Province.

The data suggest a comparatively low “success” rate for plaintiffs in semiconductor patent disputes.   Amongst the 183 reported judgments, only 51 cases were fully or partially successful — a 38.34% success rate.  This compared to an overall success rate of about 80% for litigants in patent cases in 2014 in China, as reported by Bian Renjun at Berkeley. Cases were not reversed to a significant degree on appeal; 60 out of 70 cases supported the original decision of the first instance court.  Amongst the “top 10 “ courts in terms of litigation volume, the success rate for semiconductor patent plaintiffs varied dramatically.   Guangdong had the highest success rate (60%), followed by Beijing (43.75%), Zhejiang (23.08%) and Jiangsu (19.05%).  76 of 77 successful litigants obtained an injunction to stop infringement; one litigant did not request an injunction.

Regarding administrative reviews, 117 out of 140 cases involved affirming the original administrative decision, an “affirmance rate” of 83.57 percent.  Eighty one out of ninety cases were affirmed on appeal.

The United States was the principal foreign civil litigant, with seven cases, followed by the British Virgin Islands and the Netherlands, each with two cases.  The United States was the principal first instance administrative plaintiff challenging SIPO’s decisions, with 30 cases, followed by Japan (5), Netherlands (3) and several countries with only one civil case (France, Germany, Cayman Islands, Korea,   Singapore and Israel).

I draw the following tentative conclusions from this data:

  1. Success rates for semiconductor cases vary dramatically by jurisdiction in China. My guess is that the Guangdong courts, which have the highest success rates, have greater expertise in both semiconductor patent litigation and patent litigation overall, which may make them more “expert” on these matters. Due to variations in success rates amongst jurisdictions, the semiconductor sector is a useful example of why China needs a national appellate IP court.
  2. No matter what major court one looks to, success rates for these cases are lower than the average for other types of patent litigation. This may suggest either a lack of familiarity with the technology or an unduly skeptical view of the courts regarding semiconductor patent assertions at this time. Considering that the vast majority of the cases do not involve foreigners, the low success rate primarily affects Chinese litigants.
  3. Foreigners, and especially Americans, use the courts primarily to litigate patent validity matters. There were 4.5 times more administrative semiconductor patent cases brought by Americans compared to infringement cases. Overall foreigners brought four times more validity cases compared to infringement cases in this area.  This means that the Beijing IP Court, which hears all validity disputes, plays a key role for foreigners on semiconductor patent matters.  Semiconductor patent cases also follow the general pattern where foreigners are disproportionately willing to challenge SIPO in court, but are less willing to bring infringement cases to final adjudication.
  4. Utility model and design patents are frequently asserted in patent disputes in China and may have value to foreign companies needing to protect their IP in this important market.
  5. The Fujian courts do not appear in this IP House report. However, Fujian has already heard one high profile case (AMEC v Veeco), which was settled and does not appear to be publicly available at this time. The second high profile case, involves Micron Technologies, and is currently on-going.

I hope to blog further about the AMEC cases in the United States and China in a subsequent posting.

 

April 24 – May 7, 2018 Summary

1.NPC Standing Committee Releases 2018 Legislative Plan. The NPC Standing Committee (NPCSC) on Friday released its annual legislative plan for 2018. As usual, the plan is divided into two sections—the first listing specific legislative projects slated for discussion at the NPCSC’s remaining five sessions in 2018, and second setting forth general guiding principles for its legislative work this year. The plan divides the legislative projects into three categories: (1) those for continued deliberation (that is, those carried over from 2017); (2) those for initial deliberation (that is, bills first submitted in 2018); and (3) preparatory projects.

Below is a list of laws and amendments that implicate IP matters:

E-commerce Law 电子商务法: passed under initial deliberation and is set for continued deliberation. December 2016 draft, October 2017 draft. 

Patent Law (Revision) 专利法(修订): set for initial deliberation in June. Draft released for public comments by the State Council in December 2015.  There have been several blogs previously on the drafting process and controversial issues.

Foreign Investment Law 外商投资法: set for initial deliberation in December. Draft released by the State Council for public comments in January 2015

The 2018 legislative plan also includes a list of preparatory projects, most of which won’t be submitted for deliberation this year. That list includes an Atomic Energy Law and Export Control Law and revision/amendments to Copyright Law.

2. New initiatives released by SIPO on World Intellectual Property Day. During a press conference for the World Intellectual Property Day, Shen Changyu, head of SIPO, made remarks of new initiatives planned by SIPO. According Shen, China is revising its Patent Law and establishing a punitive damages system for intellectual property infringement to increase the cost of illegal behavior and create a deterrent effect. In addition, China pledged to establish more intellectual property protection centers, in addition to the 19 intellectual property protection centers established nationwide. Meanwhile, SIPO planned to release a working guide for Anti-Monopoly law in the field of intellectual property. Should SIPO move ahead with this project, it may be an indication of an increased role for it in the newly reorganized government structure which it shares with China’s antitrust agencies.

As reported before, SIPO and other IP agencies are under reorganization. According to Shen, after the reorganization, SIPO will become the world’s biggest IP office. The new office will have 16000 staff, with 11000 patent examiners and more than 1500 trademark examiners.

3. China’s top court rules in favor of Dior in trademark case. In a judgement on World Intellectual Property day, China’s Supreme Court ruled in favor of Dior in a suit against the Trademark Review and Adjudication Board after a multi-year court battle. The board wrongly rejected a 2015 application by Dior to register a trademark of its tear drop shaped J’adore perfume bottle, the top court said in a statement on its website. Alert blog readers may remember that the Michael Jordan trademark case was similarly held on World IP Day in 2016.

4. Shanghai seizes U.S.-made microchip equipment over IPR. At the start of 2018, Chinese company Advanced Micro-Fabrication Equipment Inc (AMEC) learned that U.S. equipment suspected of infringing the company’s patents would arrive at Shanghai Pudong International Airport. Shanghai customs authorities then seized the suspected products, Jiefang Daily reported on Friday, citing customs officers. Customs suspended the clearance of the products worth 34 million yuan ($5.36 million). With Customs’ involvement, the U.S. company, whose name was not revealed, negotiated with AMEC. The two sides agreed to settle the dispute by offering cross licenses to each other. Chinese media reported that the case is a rare but important example of using Chinese Customs remedies to address imports of products infringing a Chinese patent to effect a cross-license.  The case appears to be a settlement of a long running dispute between Veeco Instruments of Plainview, NY and AMEC, which was reported in the western press, including the trade press, and also involved invalidity challenges, US court cases and an infringement law suit in Fujian province.   According to the western press on December 7, 2017 the Fujian High Court had granted AMEC’s motion for an injunction prohibiting Veeco Shanghai from importing, manufacturing, selling or offering for sale to any third party infringing an AMEC patent in China (revised June 4, 2018).
