Data 'Parallel Property Rights' — They Can Confer Status, but Can't Secure Control
Part four — and the synthesis — of Hong Yanqing's (洪延青, 网安寻路人) study notes on China's 'separation of three rights' data-property framework takes up 'parallel property rights' (数据平行财产权): how to allocate rights when the *same* data is held, used, and operated by *multiple* parties at once. Building on Xiong Bingwan and Zhuang Hongshan's 'one-data, multiple-rights' (一数数权) idea — data is non-rivalrous and copyable, so the same right over the same data can sit with several parties without excluding each other — Hong argues parallel property rights are best understood as *default rules* for incomplete-contract, collaborative-production settings: internally, parallel use is presumed; externally, operation is classified by data type (by-products each party may operate alone; purpose-built or fused data needs the others' consent); and parallel holders share a *joint defensive* interest against third parties. But the substance, he shows, falls back on derivative data — and here Xiong, Xu Ke (许可), and Shen Weixing (申卫星), despite different scenarios and tests, all tilt the derivative-data right to the *processor*, leaving the data contributor with contract/compensation/tort/PI remedies rather than ownership of the new product. DCC's read for overseas counsel: parallel property rights cut *attribution* uncertainty (who may use, operate, defend) but not *control* uncertainty (future use, detection, tracing, modelled value, third-party chains, ongoing compliance) — status, not control.

Why Upstream Won't Operate Its Data — Control Degradation, Derivative Data, and Irreducible Uncertainty
Part three of Hong Yanqing's (洪延青, 网安寻路人) study notes on China's 'separation of three rights' framework turns to the Right to Operate Data (数据经营权) — the right to provide data externally by transfer, licence, capital contribution, or pledge — and asks a question prior to 'what does operation transfer?': in real conditions, *will* an upstream party operate its data at all? His answer: yes, but narrowly. Control-dependent upstreams (platforms, holders of core user or irreplaceable industrial/training data) tend not to provide open, raw, autonomous access, and shift to controlled use or simply decline. The reason is structural. Once a downstream party is licensed to use data, the derivative data it produces is a *new object*: the upstream's *erga omnes* (对世) control over the raw data does not reach it, leaving the upstream — at most — a contractual claim against one counterparty. Hong then catalogues the uncertainties an upstream faces *ex ante*: some that attribution rules could touch but can't eliminate (qualification of the output, default ownership, good-faith of the processor, measurement of remedy), and some no rule can reach (combinatorial/unforeseeable value, undetectable misuse, the privity-and-insolvency chain, fusion and co-ownership, abstraction leakage into model parameters and learned skills, personal-information exposure, and counterparty hold-up). DCC's read for overseas counsel: this is the rigorous explanation of why Chinese data 'supply' is thin and why sandbox / privacy-computing structures dominate — defining a right does not supply the conditions to exercise it.

When the 'Right to Use Data' Goes External — Provision, Derivative Data, and the Erosion of Upstream Control
Part two of Hong Yanqing's (洪延青, 网安寻路人) study notes on China's 'separation of three rights' data-property framework turns to the Right to Use Data (数据使用权). The official definition (国家数据局, Common Data Terms Batch 2) makes the use right an *internal* power — 'I use my own data' to process, aggregate, analyse, and form derivative data — exercised on the premise of *not* providing data externally. So 'granting a use right to a downstream party' is not the use right travelling outward; it is the upstream party exercising its **operation right** to license, while the downstream party acquires a use right. That externalisation flips the downstream's legal position from PIPL **entrusted processor** (委托处理) to **provision** (提供) or **joint processing** — triggering notice and *separate consent* for personal information, and the Network Data Security Regulation's contracting duties. And because a strong use right lets the downstream form **derivative data** (衍生数据) — models, scores, indices, labels — value migrates downstream even though the raw data stays upstream. DCC's read for overseas counsel: in China data deals the use right is real but never self-bounding; whether a partner will grant an open, autonomous use right depends on its business model (control-dependent vs monetisation), and the default structure you should expect is *controlled use* (sandbox, privacy computing, federated modelling), not a clean copy.

Derivative Data Products and Public Data Opening — Legal Challenges and Compliance Points
As China opens public-sector datasets for commercial exploitation, companies building derivative data products (衍生数据产品) face a layered compliance problem: the definition of 'derivative data' in the National Data Administration's 2025 glossary is deliberately high-threshold (substantial transformation, significant value uplift); provincial rules on automated collection, source-labelling, and sensitive-data assessment are inconsistent; and a three-way collision between the open-data rules, third-party platform terms, and the 2025 Anti-Unfair Competition Law amendments has no clean resolution. Wang Yi and Yu Hao (both DEXCO-certified partners at Global Law Office Shenzhen) map the definitional landscape, five categories of operational red lines, and four protective strategies — including the new data-specific provision in the revised Anti-Unfair Competition Law — for practitioners building or advising on derivative-data businesses.
