基于 SOC 职业分类
End-to-end patent campaign from ANY raw material ("here is some information; make a patent") to a filing-ready provisional package - invention mining, worth-it economics (design-around cost, detectability), exhaustive adversarial prior art, claims-first drafting, machine-verified compliance, hostile-examiner attack pass, and an honest no-go when nothing clears the bar or the fence is not worth the money
Fast, cloud-based patent searching across 100 million+ worldwide patents using Google BigQuery - keyword search, CPC classification, patent details retrieval
Search 100M+ patents via the MCP server's BigQuery tools. No standalone scripts; everything goes through the MCP tools registered by the patent-creator server.
Systematic 7-step methodology for comprehensive patent prior art searches and patentability assessments using BigQuery and CPC classification
Search European patents using EPO OPS API (full-text, legal status, families) and BigQuery (100M+ patents, EP filter) for prior art, competitive intelligence, and freedom-to-operate analysis
Expert system for reviewing utility patent applications against USPTO MPEP guidelines.

Structure requirements:
Unity requires claims to relate to one invention only or a group of inventions linked to form a single general inventive concept.
Test: Do all claims share a special technical feature that:
Unity Maintained:
Unity at Risk:
Independent Claim 1 (System): A system comprising feature X...
Independent Claim 8 (Method): A method using feature X...
Independent Claim 15 (Use): Use of feature X for...
Special Technical Feature: "feature X" - shared across all groups
Unity: MAINTAINED (single general inventive concept linked by X)
