Full case nameQihoo 360 v. Tencent, Inc.

Stanford Law School China Guiding Cases Project, English Guiding Case (EGC78), Apr. 7, 2017 Edition

Qihoo, the producer of 360 Safeguard, is under direct threat from QQ Doctor, which gained 40% of the Chinese market overnight when it bundled with Tencent QQ. On September 27, 2017, Qihoo released a privacy guard software that shows QQ's suspicious spying activities on its users. Tencent responded with a fabricated report alleging Qihoo was under investigation for ads involving pornographic web sites, as well as rallying support from Qihoo's competitor in the anti-virus front like Baidu, Kingsoft and Kaspersky Lab.[1]

Later Qihoo alleges that QQ scans the installed programs in user's computer based on a "super black list", and continues with personal attacks on Ma Huateng, Tencent's billionaire CEO who has been receiving government subsidies for housing. Qihoo also updated the privacy guard to block ads in QQ,[4] to Tencent's furious objections including an unfair competition lawsuit and later an update that blocks itself from running on machines with 360 Safeguard installed. Hundreds of millions of Chinese computer users were forced to choose sides, either to uninstall QQ or 360's privacy guard.[5]


Litigation at the Guangdong High People's CourtEdit

The Guangdong High People's Court issued a judgement[6] that was both controversial and highly criticised by commentators and the Supreme People's Court. In their judgment they held that: The relevant geographic market was worldwide - This meant that companies like Facebook and Twitter, which are banned in China, were considered to be competitors of Tencent. The relevant market included social media sites, email service providers and others.

Litigation at the Supreme People's CourtEdit

After lengthy litigation that went through Guangdong High People's Court and the Supreme People's Court, Tencent was found to not have abused a dominant market position in a controversial decision.[7][8][9][10] Dissatisfied with the decision of the Guangdong high Court, Qihoo decided to appeal.

This is a case of the “abuse of dominant market position”, the first AML private enforcement case that was initially brought to and examined by the provincial High Court, then appealed to and finally judged by the Supreme Court, and by far, the Supreme Court’s written judgement is the best and most professional, both judicially and technically, judicial judgement of its kind ever amongst all AML cases in China. Given the judicial power and nature of the Supreme Court, this judgement established and reaffirmed several very important judicial rules with precedent case law effect insofar as the private enforcement of AML is concerned. These important judicial rules include:

(1) reaafirms the doctrine of semper necessitas probandi incumbit ei qui agit (he who alleges must prove) with regard to the allocation of onus probandi (burden of proof) in the AML judicial case

(2) defining relevant market is not a purpose but instead rather a methodology in assessing the relevant undertaking’s market power and the influence power of the alleged monopoly conduct on to the competition, as such it is not compulsory to specifically and exactly define the relevant market in every AML litigation of abuse of dominant market position

(3) an HMT (hypothetical monopoly test) based on tools of SSNIP (small but significant and non-transitory increase in price) or SSNDQ (small but significant and non-transitory decrease in quality) may be conducted in defining the relevant market but should be conducted carefully with cautious

(4) the related market situation and technology development trend post the litigation may be taken into consideration in defining the relevant market

(5) market share is not the only one element in concluding dominant market position

(6) multi elements should be comprehensively evaluated in defining the dominant market position, including but not limited to: (1) the market share of the undertaking in question and the competition situation of the said market; (2) the control ability of the undertaking in question in the said market; (3) the financial and technical status of the undertaking in question; (4) the degree of dependence of other undertakings on the undertaking in question; and (5) the degree of difficulty to access to the relevant markey by other undertakings

(7) if the relevant market is clearly defined and the alleged undertaking does not have dominant market position, normally it is not necessary to conduct an abuse behavior analysis and it can be directly concluded that such undertaking did not have abuse behavior; however, if neither the boundary of the relevant market nor the dominant market position of the alleged undertaking is clear or if the alleged undertaking had dominant market position, “effect examination” may be carried out so as to determine if the alleged conduct was lawful or not

(8) the “tie-in” under the AML is illegal if it meets all of these criteria: (1) the base product and the “tie-in” product are independent to each other, (2) the undertaking has dominant market position in the base product market, (3) certain enforcement implemented upon the buyer who became lack of other options but to accept the tie-in product, (4) the tie-in could not be justified, was contrary to the commercial or consumer practice or ignored the functionalities of the products, and (5) the tie-in gave rise to negative effect to the competition

(9) if an undertaking successfully proved the alleged monopoly conduct was justifiable under AML does not mean such undertaking has automatically and same successfully proved the monopoly conduct has not caused negative effect of exclusion or restriction of competition.

Designation as a Guiding CaseEdit

Qihoo v Tencent was designated as a guiding case by the Supreme People's Court. Whilst China does not have case law, the Guiding Cases can be considered to be persuasive precedents.


Yu Fei, CEO of Langezhiyang International Sales Consultant Principal, speculates that the dispute is resulted from poor competitive strategy.[1]

In a poll conducted by Sina, 1.06 million users, or 79% of the participants, agree that the two companies "care more about their business interests than about their users."[11]

Kingsoft and Kaspersky made their security services free for one year shortly after the dispute escalated.[11]

On November 4, 2010, the day after Tencent stopped messaging service on computers with 360 installed, TencentHolding (SEHK700) lost 10.6 billion HKD, or 3.1% in market capitalization, including 1.1 billion HKD for Tencent CEO Ma Huateng. Kingsoft (SEHK3888) jumped 17.86% and gained 784 million HKD in market cap. Another instant messaging software producer Beijing Shenzhou Taiyue Software Corp., Ltd (Shenzhou Taiyue) (SZSE: 300002) increased by 3.7%.[12]

Maybe Microsoft's MSN is the winner. It is agreeing to integrate their products with Sina "in areas including microblogging, blogging, instant messaging, information content and mobile services."[13][14]

On 10 Nov 2010, 360 Qihoo says they are going to resume their product's compatibility with QQ.[15]
