The San Francisco Intellectual Property board

This board maps the best Intellectual Property law firms in San Francisco into worded tiers as of July 2026. Each band is an editorial judgement of Intellectual Property standing in San Francisco; within a tier no firm outranks another, and monthly order is a locator, not a league table.

Limits of this assessment

  • A tier is Sartori’s editorial opinion, not a fact about the firm or a client-satisfaction measure.
  • Facts are mapped from public sources and shown as bands; they lag reality by weeks or months.
  • No third-party legal-directory band is used as an input.

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

10–24 firms earn a tier in San Francisco within this scope (banded).

Disclosures

Firm names used nominatively (factual). All counts shown as bands, never precise headcounts. No firm logos. Report an error via the site contact form.
