Abstract

fetched live from OpenAlex

This paper explores the dynamics of the transfer of U.S. patents and the significance of the initial missallocation of patent property rights.Here we find that the initial missallocation of patent property rights is large and differs substantially across patentees and technology fields.We also find that the probability of a patent being traded depends on a number of factors -the age of the patent, the number of citations received by a given age, the patent generality and whether the patent has been previously traded or not.We will also analyze and interpret this new evidence using a theoretical model of patent transfers and renewal.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
