Is PatentSec-12B state of the art?Pending benchmarks.Announced Oct 21, 2026; no independent results yet.
Calera Labs' patent-prosecution model, a fine-tune of Google's Gemma 4 12B instruction model for USPTO statutory reasoning: claim-element auditing, antecedent-basis checks, extension fees and response deadlines. Released as Apache 2.0 GGUF weights (Q4_K_M and Q8_0) for llama.cpp, Ollama (via an included Modelfile) or LM Studio. The first of Calera's "Bedrock Models". Not legal advice.

What would let us call it
Verdicts use only independent boards we already track. Two consecutive snapshots are required before any crown.

- Holds across two snapshots (crowns only)
What the lab claims
Self-reported. Shown for context; not used in any verdict.
Lab claim: 77.0% (218/283) on its own PatentBench v0.2.0 Layer 1 Mini split from the weights alone, and 96.5% on the 226 self-contained cases. Self-reported, unranked.
Lab claim: 92.6% on the Mini split and 99.23% on the 7,097-case full corpus when paired with Calera's hosted ICX system (not the weights alone).
