Before you file, name or build, Anteriora looks back for you: a prior-art survey of your invention, a read of your document or repository into draft matters, and a name check against the US and French trademark registers (EU, Madrid and other countries not searched). The assistant runs in a hardware-isolated machine that your computer verifies before a word is sent.
Three jobs
Describe an invention. The assistant searches about 29.6 million US, European and WIPO patent publications through a sealed search machine your computer checks first. You get the closest earlier patents, your own relevance marks, and a record anyone can verify.
Titles and abstracts, to mid-April 2026. Patents only: not papers, code, other offices or full text.
What it covers, and what it does notPoint it at a document, a folder, a git link or a GitHub repository. It lists each distinct invention it finds and writes a draft matter for each. You choose what it reads; test code can be left out.
Measured: a 1,700-line repository took about 40 minutes and produced 12 drafts. A draft is a starting point, not a filing.
How the read worksList the names you are considering. The search runs on your computer, in a local copy of the US (USPTO) and French (INPI) registers. A name is never sent to a trademark register, a search engine or a website. The report lists registered marks that resemble each name, and why.
5,741,201 live word marks; US to 30 Sep 2026, France to 16 Oct 2026. Not searched: EU marks (EUIPO), WIPO Madrid, other countries, company names, domains, logos.
Coverage and the reportHow the privacy works
You have to describe the invention to search for it. So the assistant runs in a hardware-isolated machine (confidential computing). Before any of your text is sent, the app verifies that machine by remote attestation: its hardware, and that its software matches the identity InferRoute signed and published. If a check fails, nothing is sent.
An NDA is a promise; this is a check your computer runs. Technical confidentiality, not a legal NDA.

Stated plainly
It gives no answer on novelty or freedom to operate. That is a question for a patent attorney.
It never says a name is free to use or can be registered, and it does not judge whether two marks would be confused. Not legal advice.
The record
At the end of a session you can export a record of its searches. It ships with its own verifier, so your attorney, your co-founder or an investor can check it without trusting InferRoute.
What a record shows is what was searched and what came back. It is not a filing, and it does not establish when you invented something.
For patent and trademark professionals
Run a first prior-art survey or name check on a client's matter, before a filing exists.
Your computer verifies the sealed machine first. If the check fails, nothing is sent.
The searches and what came back, with its own verifier. No need to trust InferRoute.
Not a filing, not a priority date, no opinion on novelty or registrability. A first look, not a complete search.
An NDA is a promise; this is a check your computer runs. Technical confidentiality, not a legal NDA.
Patents: titles and abstracts of about 29.6 million US, EP and WO publications, to mid-April 2026. Trademarks: the US and French registers, searched on your computer; EU marks (EUIPO), WIPO Madrid and other countries are not searched.
What the check proves, and what it cannotPlain answers
Before a word is sent, the app verifies the machine by remote attestation: its hardware, and that its software matches the identity InferRoute signed and published. Your description is then sealed on your computer to that machine, so InferRoute's relay carries it without being able to read it. Software inside that machine can read your text; the check does not prove what it does with it, cannot prove that nothing was kept, and does not hide when you sent something or how much. Every session shows what was checked, and what the check cannot prove. Read the full explanation.
No. Anteriora is a search tool. It gives you results and a record, not an opinion on patentability, on freedom to operate, or on whether a name can be used or registered. A patent or trademark attorney gives you that, and a good survey helps you brief one.
No. The prior-art survey searches titles and abstracts of about 29.6 million US, EP and WO patent publications up to mid-April 2026. It does not search full text, other offices, papers or code. It is a first look, not a complete search.
A single patent search returns in seconds. A whole session, several searches plus the writing, takes minutes. A name check takes about 10 to 15 minutes. Reading a 1,700-line repository took about 40 minutes in our measurement.
The searches are. The app keeps a local copy of the US and French registers (a one-time download of about 250 MB, about 800 MB on disk) and searches it there. A name is never sent to a trademark register, a search engine or a website. The assistant that reads your notes and writes the report runs on the sealed machine the app checks first, so it does see your names and product description.
No. The name check covers registered word marks in the US and French registers only. Company and trading names, domain names, logos, EU marks (EUIPO), WIPO Madrid registrations for France or the EU, and other countries are not searched.
