Global Patent Publications with Chinese Patent-Family Quality Measures

This dataset repository contains two Parquet files.

Files

data/cn_family_quality_master_gft.parquet

One row per Chinese focal invention patent family for 2003–2019.

It contains the cumulative patent-quality pipeline, including:

• —semantic knowledge recombination (semantic KI);
• —strict historical semantic novelty;
• —IPC-based KI robustness measure;
• —three-year and five-year forward citations;
• —CD3 and CD5 disruption measures;
• —full-window and five-year PageRank;
• —semantic KNN graph low-pass and high-pass/GFT components.

Expected rows: 10,790,043.

data/global_invention_patents_with_quality.parquet

The original global invention-patent publication table, left-joined to the patent-family quality master through family_id.

• —Original publication-level rows and columns are retained.
• —All publications belonging to the same matched family receive the same family-level quality measures.
• —quality_matched = true identifies publications matched to the Chinese focal-family quality table.
• —Nonmatched global publications remain in the file and have null added quality fields.

Expected rows: 121,309,581.

Unit of observation

• —Quality master: patent family.
• —Global result: patent publication record.
• —Matching key: family_id.

Important methodological notes

Missing KI, CD, or GFT values were not replaced with zero. PageRank zero values for families outside the identifiable citation graph are accompanied by the in_citation_graph indicator.
