FIG. 1 — REQUEST, PAYMENT AND SETTLEMENT FLOW (x402, EXACT SCHEME)

Method and scope

1.

Methodology aligned with DIN 77100 principles

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.

2.

Informed by professional valuation practice

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.

3.

Full derivation in every response

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.

4.

Portfolios from 1 to 500+ patents

Single patents, clustered portfolios or distribution-level descriptions — one request format covers all of it, with count-weighted aggregation.
