Free Wearable Corpus

A public-domain prior art commons covering watches, bracelets, rings, eyewear, hearables, headbands, patches, garments, exoskeletons, implantables, and ingestibles — across private patents, open source, science fiction, academic literature, regulatory filings, and standards bodies.

The corpus IS the prior art commons. Every entry, at the moment of timestamped commit and quarterly release, is a defensive publication. The structured data here, combined with the cryptographic timestamping in releases/, is itself the invalidity-contention material.

The corpus is a lexicon, not a catalog. Retrieval equals citation.

What’s different from the Free Humanoid Corpus

Wearable patent claims read on component combinations: form factor × sensor × algorithm. The corpus indexes each axis independently and generates cross-cuts per single tag and per intersection.

Combining a known sensor with a known wearable form factor is per se obvious under KSR / MPEP § 2143 Rationale A. The §103 argument for any (form factor × sensor) tuple is boilerplate — see OBVIOUSNESS_TEMPLATE.md. Component disclosures live in the cross-cuts. The combination argument lives in the template, once.

Component cross-cuts + one template = the §103 proof.

What it covers

Six buckets:

Bucket	Role
Private	Commercial products with disclosed engineering, including patent-thicket holders.
Open	Open-hardware and open-source wearables.
Fictional	Film, TV, comics, games, literature. Strong for §103 motivation-to-combine.
Academic	Peer-reviewed papers, theses, conference proceedings.
Regulatory	FDA 510(k), De Novo, PMA decision summaries; CE MDR/IVDR filings.
Standards	IEEE 11073, Bluetooth SIG profiles, ISO/IEC 80601, Continua Alliance.

Provenance

Quarterly releases carry three independent cryptographic timestamps attesting pre-existence:

FreeTSA (RFC 3161)
DigiCert (RFC 3161)
OpenTimestamps (Bitcoin-anchored)
