Direct answer & research summary

Sartori & Partners has completed 400+ placements since 2017 (230+ in-house), including 52 general counsel and chief legal officer searches, with a median of 11 weeks from brief to accepted offer. A NASDAQ-listed medtech in Boston accepted its successor general counsel in week 11, from a shortlist of four at day 24.

01 — The ranking

The London Intellectual Property board

A tier on this London Intellectual Property board names relative firm standing in words. Placement speaks to patents, brands, designs, soft IP and IP litigation presence on the City platform; order inside each band carries no hierarchy and is not a score.

Methodology

How tiers are assigned

Deterministic public-footprint core (local depth, practice share, seniority mix, public hiring momentum), computed relative to this market's own distribution. Tier placement is derived from this public mapped data; a per-firm public-source ledger is compiled for firms in the annual research pass and applies to those firms' factual claims, not to tier membership. No third-party legal-directory bands are used as an input.

Market scope

5–9 firms earn a tier in London within this scope (banded).
