Method

How a determination gets made.

Three status values, three confidence values, two legal regimes kept apart, and a source list on every entry. This page is the whole rulebook — if a determination in the index doesn’t follow it, the determination is wrong, not the rule.

01 — Status

Exactly one of three values.

Public domain

No copyright claim applies.

Every appearance and version the entry covers has cleared US copyright. There’s no carve-out and no later work still under protection pulling it back — the whole determination is clean, subject only to any separate trademark note (see § 03 below).

How it’s determinedThe publication date of every version in scope is checked against the US fixed-date term wall — 1930 and earlier, as of 2026. One clean pass on every covered version earns this status; if even one falls short, the entry drops to Partially free instead.

Example — Sherlock Holmes →Cleared entirely only in 2023, once Conan Doyle’s final stories aged out too.

Partially free — version dependent

Not one answer — a per-version answer.

The character or work isn’t a single yes/no. Specific designs, stories, or editions clear the term while later ones don’t — using the wrong one is exactly the trap this status exists to flag.

How it’s determinedEach distinct version — a design, a story, a specific edition — gets its own term-wall check. The entry’s version-scope field states plainly which ones are free and which aren’t, instead of averaging them into one misleading label.

Example — Mickey Mouse →The 1928 Steamboat Willie design is free; every later redesign isn’t.

Protected

Still under active rights — full stop.

The version in question hasn’t cleared US copyright, or a live trademark blocks commercial use regardless of copyright status. Nothing here is offered as free to use.

How it’s determinedA publication date after the current term wall, a renewal that kept an older work alive, or an active trademark independent of copyright — any one of these is enough to keep an entry here.

No character in the index carries this status yet — every one seeded so far cleared at least partially. For scale: a character from a book published in 1997 is still decades from the wall this rule uses.

02 — Confidence

How sure the entry is, stated out loud.

High

Settled

Backed by a clear statutory rule or settled case law, with no open litigation.

Medium

Reasonable reading

A defensible reading with some ambiguity, or an untested edge case.

Low

Flagged for review

Best-effort inference — flagged for review before it is ever shown as a paid determination.

Copyright and trademark are two regimes. We keep them in two fields.

03 — Copyright vs. trademark

A clean badge never implies the trademark field away.

These are tracked as two separate fields on purpose. A work can be fully clear of copyright and still carry real trademark risk — Zorro and Mickey Mouse are both in the character index specifically because they show this split.

Entries showing the split
04 — What this isn’t

Informational, not legal advice.

Read this before relying on anything here

OpenGlyph is informational, not legal advice. Every determination shows its sources so it can be checked, not trusted blindly. This is a pre-launch build — the character index has 6 entries, image/art search covers two of four candidate archives so far, and nothing here should be relied on commercially without independent verification.
