IP Protection
IP Protection
PriorMark protects your entire intellectual property footprint — from patent-pending inventions to your most guarded trade secrets — with permanent, tamper-proof proof of priority that exists long before any legal dispute begins.
Built on
Hedera Public Ledger
Every submission is permanently recorded on Hedera's tamper-proof consensus ledger — not a private database.
AES-256 Encrypted Storage
Full content is encrypted with AES-256-GCM before upload — stored securely in the cloud and never publicly readable.
Stripe Secure Payments
All transactions processed by Stripe. No payment data is stored on PriorMark servers.
Trade Secret Protection
Patents require public disclosure — and disclosure destroys trade secret protection. PriorMark gives you a third path: the Hedera ledger records a tamper-proof fingerprint of your submission, not the content itself. Your content is encrypted server-side and never publicly indexed or readable. If ownership is ever challenged, you produce the original; anyone can independently verify it matches the sealed record on the ledger — without premature disclosure.
Encrypted in transit / at rest
Content is encrypted with AES-256-GCM before storage — private, tamper-evident, and never publicly readable.
Fingerprint, not content
The Hedera ledger records only the SHA-3/512 hash of your submission — no content, no disclosure required to establish priority.
Produce on demand
If priority is ever challenged, produce the original. Any party can independently verify it matches the sealed ledger record.
Process
1
Fingerprint and encrypt
A SHA-3/512 fingerprint of your content is computed and stored on the ledger. Content is encrypted server-side with AES-256-GCM before being stored — never publicly readable.
2
Submit to the Hedera ledger
An HCS message containing your content hash and summary is submitted to the public Hedera Consensus Service.
3
Receive your priority timestamp
Hedera's fair-ordering consensus assigns an immutable timestamp — your official priority date on the public record.
4
Verify anytime, anywhere
Anyone can independently verify your timestamp via the Hedera mirror node — no account or login required.
Who it's for
R&D Teams
Timestamp every new development before it leaves the lab. Create an auditable trail of innovation without disclosing to competitors.
Independent Inventors
Establish your priority date before filing a patent. A ledger record predating a competitor's application is admissible prior art.
Companies & Startups
Protect IP developed before you're ready to file — or decide not to file. Lock in the date without going public.
Trade Secret Holders
Timestamp confidential IP without going public. The ledger records the fingerprint — your content stays encrypted and private until you choose to disclose.
Legal context
A public ledger record may invalidate a later-filed patent for lack of novelty under US law (35 U.S.C. § 102(a)(1)), European absolute novelty rules, and Chinese patent law — provided the disclosure predates the patent's priority date. Courts in France and China have already accepted blockchain timestamps as valid prior art evidence.
