FR-AI / ANALYSIS

Why it is worth attention

It is the first publicly curated collection of official Chinese software copyrights specifically for LLM/VLM systems, covering a diverse range of AI topics such as reinforcement learning, multi-agent systems, and embodied intelligence, while also solving GitHub's built-in PDF rendering limitations with a custom viewer.

Who it is for

  • AI researchers and practitioners interested in Chinese AI software copyright landscape
  • Legal and intellectual property professionals dealing with software registration in China
  • Developers looking for a cross-browser PDF solution for CJK-encoded documents
  • The repository author (AderonHuang) for portfolio and public attestation purposes

Use cases

  • Verifying the authenticity and details of specific copyright certificates via registration number
  • Studying the thematic distribution of Chinese AI software copyrights (e.g., RL training methods, agent systems)
  • Referencing the certificates in academic or professional work related to Chinese IP and AI development
  • Using the custom PDF viewer as a model for rendering CJK PDFs on GitHub Pages

Strengths

  • Contains 22 byte-identical PDF copies of official certificates with full metadata (registration number, issue date, scope)
  • Provides a working in-browser viewer that handles CJK fonts correctly, overcoming GitHub's PDF rendering errors
  • Offers a verification method through China's national copyright query system using the registration number
  • Indexes certificates by year and by theme, making exploration easy for different research areas

Considerations

  • No source code or implementation details are included; only the registration certificates are provided
  • All rights are reserved (no license granted) on the certificate PDFs themselves
  • The collection is limited to certificates issued by the China Copyright Protection Center and may not reflect global IP trends

LLM / VLM Software Copyright Certificates

LLM/VLM 软件著作权证书集

A public archive of officially registered LLM / VLM software-copyright certificates issued by the China Copyright Protection Center (中国版权保护中心).

📌 How to view — Click any certificate to open it in an interactive browser-based viewer (powered by Mozilla pdf.js + Adobe CJK CMap). Works in every modern browser, every account, every device. The viewer also exposes a Download original PDF button for archival use. 📌 如何查看 —— 点击任意证书条目即可在浏览器内嵌查看器中打开(基于 Mozilla pdf.js + Adobe CJK CMap)。对所有浏览器、所有账号、所有设备都兼容。查看器内还有下载原件 PDF按钮。

Total: 22 published certificates across 6 batches.


📖 About This Repository / 关于本仓库

Software-copyright registration in China is a voluntary, public procedure regulated by the Computer Software Protection Regulations (《计算机软件保护条例》) and the Software Copyright Registration Procedure (《计算机软件著作权登记办法》). For each successful application, the China Copyright Protection Center issues a numbered 计算机软件著作权登记证书 that records the software's full registered name, the rights holder, the scope of rights, and the registration number.

GitHub's built-in PDF blob viewer cannot reliably render these particular certificates because the source PDFs embed a cs=ICCBased scan image plus a CIDFont Type 2 CJK subset (SimSun) that pdf.js cannot decode uniformly across browsers and accounts (manifesting as Error rendering embedded code, Error loading PDF page number 1, or Unable to render code block).

To bypass that, this repository ships a custom HTML viewer served via GitHub Pages (adetonhuang.github.io/LLM-VLM-Software-Copyrights/). The viewer uses Mozilla's pdf.js with Adobe's official Chinese CMap CMap files loaded from a CDN — which handles the SimSun subset correctly — and renders every certificate for every visitor consistently.

The PDFs themselves in this repository are byte-identical copies of the originals — no decompression, no re-rendering, no font stripping.
