What's new in Stratensight

Expert Mode — build precise patent queries with 151,000+ CPC codes autocomplete, AND/OR operators, live patent count, and shareable query URLs

Patent family deduplication — the same invention filed in multiple countries now counts as one family, so corpus and scores reflect the true invention count (audit-grade accuracy)

Assignee normalization premium — a 803-variant canonical dictionary now drives scoring: country tags stripped, academic abbreviations resolved, invalid entities filtered automatically

Signal integrity improvements — the verdict is conditionally flagged when CAGR is driven by an indexing artifact, and Lifecycle shows 'Insufficient temporal data' when the dataset spans less than 2 years

Landing premium refresh — Stratensight brand H1, sharper tagline, use case answers, simplified demo

Filing Intelligence™ + Portfolio Positioning™ — competitor profiles and client portfolio mapping

Client portfolio overlay on technology clusters with whitespace badges

Clickable competitor profile drawer — open any patent owner from the Competitive Landscape

Report engine — Sprint A/B fields propagated to PDF/Word/PPTX/Excel

Silhouette score per cluster — quality badge surfaces in Deep Dive

HDBSCAN density-based clustering replaces KMeans for sharper technology groupings

UMAP dimensionality reduction improves clustering quality

Contrastive cluster labels via Haiku — sharper cluster names

Sentence-transformers embeddings replace TF-IDF — semantic clustering foundation

Whitespace Score™ — strict gate when clusters are unreliable

CPC Guard — hard block on low-diversity datasets, frontend warning banner

Silhouette score persistence — cluster quality badge per analysis

Query transparency — dataset provenance card, CPC confidence badge, collapsible CQL

Deep Dive refresh — 7 sections refactor, persona singular voice, dead code cleanup

GDPR Phase 1 — DSAR endpoint, retention purge, data processor agreements
