# phonetic_search

Find trademarks whose WHOLE mark sounds similar to the given mark (Metaphone + trigram, whole-mark similarity threshold). LIMITS: it compares entire marks, so multi-word marks that merely CONTAIN a sound-alike word are invisible to it — "KWIK REWARDS" will NOT surface for a QUICK query even though KWIK sounds like QUICK. Thin or empty results are NEVER evidence that no sound-alike marks exist and NEVER support an availability/clearance conclusion: cross-check with list_marks_containing_term on the likely variant spellings (e.g. KWIK, QUIK, QWIK for QUICK — it enumerates ALL containing marks, including compounds), and answer availability questions with run_knockout_search, the actual clearance engine.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why phonetic_search is rated Low

This tool retrieves and queries trademark data using phonetic matching algorithms. It has no side effects: it does not create, modify, delete, or execute code/commands. The tool searches a read-only database of 13.7M+ USPTO trademarks and returns results.

From the tool's own definition: "phonetic_search: 'Find trademarks whose WHOLE mark sounds similar to the given mark' — performs phonetic matching and similarity comparison against existing trademark database; returns matching results without modifying, deleting, or executing external…"

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call phonetic_search to retrieve information from GleanMark Trademark Search without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)
