How it works

From a product description to a shortlist of names

  1. Step 1

    Search the mechanism, not the product name

    Examiners index inventions by how they work. "Collapsible silicone bottle with magnetic lid latch" finds art; "Burple bottle" finds nothing.

  2. Step 2

    Use examiner vocabulary

    Run several phrasings of the same idea — retaining collar, compliant hinge, magnetic latch, living hinge. Prior art that reads on your claim often uses none of the words you would pick.

  3. Step 3

    Read the claims, not the title

    A patent only covers what its claims say. Open the record and read claim 1 — that is the boundary. The title and abstract routinely sound far broader than the protection actually granted.

  4. Step 4

    Check whether the record is still in force

    Expired and abandoned patents are free to practice. A granted US patent runs 20 years from its earliest filing date, and lapses earlier when maintenance fees go unpaid.

FAQ

Product naming questions we get asked

Is this US patent search free?

Yes. No account, no email gate, no limit beyond a fair-use cap that stops automated scraping. Every result links to the official published record.

What does the search cover?

The full text of US granted patents and published applications, with an option to widen to worldwide records. It does not cover unpublished applications — filings stay confidential for roughly 18 months, so recent art may not be visible to anyone yet.

I found nothing. Does that mean my idea is patentable?

No. An empty keyword search is a weak signal. Novelty is judged against all prior art worldwide, in any language, including non-patent publications and products already on sale. Treat a clean search as permission to keep going, not as an opinion.

I found something close. Is my idea dead?

Usually not. Compare your product against the claims, not the pictures. Most concepts survive with a change to the mechanism, and the close art often tells you exactly where the open space is.

What is the difference between a granted patent and a published application?

A granted patent is an enforceable right with examined claims. A published application is a filing that has been made public but not yet granted — its claims may narrow substantially or never issue at all. Both count as prior art.

Does this replace a professional prior-art search?

No. This is a keyword screen. A patentability or freedom-to-operate opinion requires a classification-based search and a claim-by-claim analysis by a registered patent attorney or agent.

Do you provide legal advice on patents?

No. LA NPDT is a product development firm, not a law firm. Everything here is general information and automated screening. For legal advice, work with a registered patent practitioner.
