Appraxa applies a relief-from-royalty methodology aligned with the general principles of DIN 77100, the German standard for monetary patent valuation. Structured risk factors and assumptions are informed by professional valuation practice. Every response includes its principal inputs, assumptions and calculation steps.
Experimental service for professional users and authorised software agents only. Not intended for consumer use.
Relief-from-royalty (license price analogy): revenue basis, patent-specific risk discounts across seven factor groups, a license rate derived from comparable published sources and a six-criteria scoring model, corporate factors, and discounting — the same calculation chain used in professional valuation engagements.
The simplified risk mapping (granted vs. application, ownership, workaround, enforcement, remaining term, US coverage and more) has been developed with reference to completed professional valuation work and has been reviewed by an independent patent attorney.
Point value, value range, per-patent risk discounts, the applied license rate with its comparable sources, year-by-year present values and a confidence rating. No black box — an agent (or its operator) can audit every number.
Single patents, clustered portfolios or distribution-level descriptions — one request format covers all of it, with count-weighted aggregation.
