AIA §135 · §273 · DTSA · Berne · eIDAS

Patent and trade-secret disputes are decided on when, not what.

Priority turns on the earliest date a claim can be shown to have existed. Reasonable measures to keep the secret is a statutory requirement. In both cases, the question is when, and a blockchain-anchored hash answers it without revealing the work.

The law

Every IP and trade-secret framework asks the same question: when.

The statutes, the regulations, and the courts all converge on one requirement: prove the document existed at this date, in this form, to a party that does not trust you.

AIA §135 · 35 U.S.C. §135
Derivation proceedings

Where a named inventor is accused of having derived an invention from another party without authorisation, the petitioner must prove prior conception and communication by a preponderance of the evidence. The factual question at the heart of every derivation proceeding is creation date. Who had the idea first, and what did they document at the time?

AIA §273 · 35 U.S.C. §273
Prior commercial use defence

A party facing patent infringement can defend on the basis of prior commercial use, but must prove that use occurred at least one year before the earlier of the effective filing date or the date of public disclosure. The burden of proof is clear and convincing evidence, one of the highest civil standards.

DTSA · 18 U.S.C. §1839(3)
Trade-secret reasonable measures

A trade secret is legally protectable only where the owner thereof has taken reasonable measures to keep such information secret. Courts assess this case-by-case. Systematic documentation of what is confidential and when it was created, without disclosing the content, constitutes a reasonable measure.

EU Trade Secrets Directive 2016/943 · Art 2(1)(c) + Recital 14
Reasonable steps (EU)

The EU equivalent of the DTSA requires that information be subject to reasonable steps under the circumstances. Recital 14 explicitly references appropriate technical measures including marking documents as confidential as a basis for the reasonable-steps requirement.

Berne Convention · 179 countries
Copyright ownership

Copyright exists at the moment of creation, without registration. The burden of proving creation date is entirely on the rights holder. In disputes over ownership or infringement, the factual question is who created this work and when. There is no registry that answers this question automatically.

FRE 902(13)/(14) · eIDAS Art 41
Blockchain admissibility

US Federal Rules of Evidence 902(13) and (14) provide for self-authentication of records generated by electronic processes producing accurate results. eIDAS Art 41(2) creates a legal presumption of accuracy for the date and integrity of a qualified electronic timestamp, binding across all 27 EU member states.

An honest line on patents

A private blockchain timestamp is not §102 prior art. Under the AIA, prior art requires public disclosure. immut does not create prior art: the file stays private, only the hash is on a public ledger. For the patent right itself, you still need to file. Where immut is directly relevant in the patent context is derivation proceedings (§135), prior commercial use defences (§273), evidence of the inventor's own pre-disclosure creation (§102(b)(1) grace period), and foreign filing licence date compliance (§184). These are not edge cases. They are the contested evidentiary questions in real patent disputes.

The evidence gap

An authentic document and a backdated one are forensically identical.

Invention records, lab notebooks, design files, and trade-secret inventories in Word, Google Docs, GitHub, and email are all editable. Metadata can be changed. File timestamps can be rewritten. No court or PTAB examiner can tell the difference by inspecting the file.

Git histories

Can be rewritten with administrative access. Internal audit trails live in the same editable system they are meant to prove.

Email timestamps

Generated by the sending client and editable. Server logs may corroborate, but are under third-party control and subject to retention policies.

Cloud storage

File timestamps show when a file was uploaded or modified, not when it was created. They are under the control of the same organisation being questioned.

Cases

The party with better documentation of when they had the idea won.

In every case below, the substance of the invention was not in question. The when of its creation was. Ninety-one percent of the most innovative products of the past few decades were not patented. For those 91%, trade-secret law is the only protection available, and it requires contemporaneous evidence.

Superpharm v. Megapharm
Patent priority proceeding
Patent lost

Lab notebooks were found not to have been written when they claimed. Invention priority date pushed back two months. The patent was lost not because the invention was invalid, but because the date could not be established.

Medichem v. Rolabo
Patent priority proceeding
Priority lost

Lab notebooks were found fraudulently backdated. Some were authentic; others were not. No forensic method available to the court could distinguish between them from the documents alone.

Stern v. Columbia University
Inventorship dispute
Inventorship disputed on evidentiary grounds

Notebooks were not contemporaneously witnessed as required for pre-AIA corroboration. The factual question was not whether the inventor had the idea, but whether the records credibly showed when.

Broad v. UC Berkeley (CRISPR)
PTAB / Federal Circuit
Multi-billion-dollar dispute on notebook credibility

The entire dispute turned on the credibility of lab notebook maintenance at two world-class institutions. Two of the most sophisticated IP programmes in existence produced a record that was sufficient but fragile.

Global Health Solutions v. Selner
§135 derivation proceeding
Weaker evidentiary position

Email timestamps were offered as corroborating evidence. Accepted as corroboration, not as primary proof. The court noted that email metadata is generated by the sending client and is editable, placing it in the weakest evidentiary category.

How it works

The hash is public. The work stays private.

A SHA-256 hash is a one-way fingerprint. Given the hash, no-one can reconstruct the original file. Given the original file, anyone can verify the hash matches. The blockchain record proves existence and date without revealing the invention, the trade secret, or the original work.

risk-assessment.docxSHA-256on device0xa3f9…b2c7XRPL public ledgerSTAYS ON DEVICEPUBLIC
01
File never leaves your device

The SHA-256 hash is computed locally. The invention disclosure, lab notebook, or trade-secret marker is not transmitted, stored, or visible to immut.

02
Hash anchored to the XRP Ledger

The hash is written to the public XRP Ledger at the moment you create the record. Once written, no party can alter or delete it.

03
Certificate issued immediately

immut generates a court-ready certificate containing the hash, XRPL transaction ID, ledger sequence number, and UTC timestamp.

04
Proof outlives immut

The record lives on a public blockchain and remains verifiable even if immut ceased to exist. No dependency on immut's servers or continued operation.
