Abstract
The emergence of blockchain technology has sparked debates about intellectual property (IP) protection. While most scholars advocate for patent protection as the optimal solution, China's current patent system faces inefficiencies—lengthy application cycles, low approval rates, and potential hindrances to technological progress. This paper evaluates various IP protection methods, analyzes the suitability of China's Patent Law for blockchain innovations, and proposes reforms inspired by the U.S. Subject Matter Eligibility Test and open-source licensing models. Recommendations include extending patent protection periods and restructuring审查 (examination) processes to better accommodate blockchain's rapid evolution.
1. Introduction
Originating from Bitcoin, blockchain operates as a decentralized data structure leveraging cryptographic techniques, peer-to-peer networks, and consensus mechanisms. China's IP framework offers diverse protections—copyrights, patents, trade secrets, and trademarks—each applicable to different aspects of blockchain technology.
2. Blockchain and IP Protection Frameworks
2.1 Copyright
- Protects: Software code, documentation, and technical writings under China’s Copyright Law and Computer Software Protection Regulations.
- Limitations: Abstract concepts (e.g., decentralization models) are excluded.
2.2 Patents
- Global Trend: Over 2,500 blockchain-related patents filed worldwide since 2008.
- Requirements: Innovations must demonstrate technical features beyond mere algorithms (per Patent Law, Art. 25).

2.3 Trade Secrets
- Applicability: Protects confidential technical/operational information (Anti-Unfair Competition Law, Art. 10).
- Challenges: Incompatible with blockchain’s open-source ethos.
2.4 Trademarks
- Role: Safeguards brand identity but not underlying technology.
3. Patentability of Blockchain Technology
3.1 Core Blockchain Tech
- Hurdle: Distinguishing technical implementations from abstract ideas (e.g., distributed ledgers).
- Solution: Combine conceptual models with tangible tech (e.g., consensus algorithms + hardware).
3.2 Cryptocurrencies
- Barriers: Excluded under Patent Law (Art. 5) due to lack of legal tender status (e.g., Bitcoin) and public秩序 (order) concerns.
4. Challenges in Patent Protection
| Issue | Impact |
|---|---|
| Economic Misalignment | Long approval periods stifle fast-paced innovation. |
| Open-Source Conflicts | 90% of blockchain projects use开源 (open-source), opposing patent monopolies. |
| Vague Legal Standards | No clear guidelines for "blockchain + tech"专利 (patent) eligibility. |

5. Proposed Reforms
5.1 Adjust Patent Terms
- Shorten protection periods for blockchain to accelerate迭代 (iteration).
5.2 Adopt U.S. Eligibility Tests
- Implement Mayo/Alice two-step test to filter non-technical claims.
5.3 Leverage Open-Source Licenses
- Use GPL/MIT licenses to regulate derivative works while preserving innovation.
6. Conclusion
A hybrid approach—refining patent laws, embracing开源 (open-source) norms, and streamlining审查 (examinations)—is critical to balancing IP protection with blockchain’s collaborative nature. Stable, predictable standards will incentivize inventors while avoiding monopolistic pitfalls.
FAQs
Q1: Can blockchain algorithms be patented?
A: Only if integrated with specific technical applications (e.g., hardware optimizations).
Q2: Why are cryptocurrencies often denied patents?
A: They lack legal recognition and may disrupt public秩序 (order).
Q3: How do open-source licenses impact blockchain IP?
A: They encourage sharing but complicate proprietary claims.
Q4: What’s the average blockchain patent approval time in China?
A: Currently ~18.5 months—posing risks for fast-evolving tech.
