01 — The ranking
The San Diego Patent Litigation board
Sartori's view of the best Patent Litigation law firms in San Diego groups 4 firms by relative Patent Litigation market position in San Diego. Tiers are plain-language labels only — never scores — and within-tier sequence rotates without implying rank.
This band holds the firms whose Patent Litigation presence defines the San Diego standard. Labels are editorial words, not scores; monthly order inside the tier carries no meaning.
Highly active firms show sustained Patent Litigation mandate flow and visible patent-trial bench strength in San Diego, just below the market-leader band. Order inside the tier is non-hierarchical.
All counts are shown as bands, never precise headcounts. Notable firms sit outside the tiers by design: verified minimal presence, not assessed at full tier depth.
