Added Matter
What it is
AI-powered patent prosecution and drafting platform focused on European Patent Office work. Core feature is an EPO examiner statistics dashboard that surfaces behavioural data on individual examiners to inform prosecution strategy. Also automates patent specification drafting, IDS citation formatting (PTO/SB/08), office action response generation, and invalidity argument creation. The examiner dashboard and drafting tools appear to be separate modules — unclear whether examiner insights feed directly into response drafting or require manual interpretation. London-based startup, founded 2022 (Tracxn; product may have launched 2023 per TLTF), 2-10 employees, unfunded. Pricing at $495/user/month (introductory). Not listed in major 2026 AI patent tool roundups — very low market visibility compared to PatentPal, Specifio, Solve Intelligence, DeepIP.
Who It’s For
- Patent attorneys/agents handling EPO prosecution who want data-driven examiner insights
- IP boutiques looking to reduce drafting time on patent specifications
- In-house IP teams filing high volumes of European patent applications
What We Haven’t Verified
- No practitioner reviews or case studies found — feature claims are based on vendor materials and third-party listing descriptions
- The branded search term “added matter” overlaps with the EPO legal concept of impermissible amendments, making independent search traffic data unreliable
- USPTO vs EPO feature depth is unclear — marketing emphasises EPO but IDS formatting (PTO/SB/08) is US-specific
