Tell us what you saw | EP 2 052 169 B1 | IC Knowledgebase Prior Art Register

What did you see, and roughly when?

Your words, not the patent's. Claims are written abstractly and nobody ever marketed anything using that language, so the archive search below is seeded from what you type here.

Company or manufacturer

Product or system name

Roughly when

Web address, if you know one

What was it, in a sentence or two

Add your own evidence

Drawings, photographs, brochures, manuals, site records. Arrival is logged and hashed the moment it lands.

File

How is that date corroborated

Reference or link for that corroboration

Submission strength: weak (15/100)

This is documentary evidence, so staying anonymous costs you nothing on the score.

Was it public at the time?

This decides everything. Work shared under an NDA was never public, so it cannot be prior art no matter how old it is.

It was published, issued or on sale, and anyone could have seen itIt was shared in confidence or under an NDAI am not sure

Your identity

Named: I'm willing to be identified with this submissionAnonymous

Your name

Your email

I would be willing to confirm this in a witness statement if needed

I have the right to share this and I am content for it to be public and permanent

IC Knowledgebase does not file anything, does not act for you, and is not a firm of patent attorneys. This register collects and dates evidence so that somebody who is qualified can use it.
