How it works
You type what your invention does in plain language. PriorScout weighs that meaning against existing patents and returns a novelty reading with the filings behind it. Here is a search someone actually ran.
Typed in
Capturing carbon dioxide from flue gas using a rotating honeycomb adsorber.
Came back
Strong prior art found
Existing filings cover most of what was described, so as written the idea is unlikely to be novel.
What it covers
Find earlier patents that describe the same idea before you file, so a rejection does not cost you the application fee.
A quick patentability search to gauge whether your invention is new enough to be worth a filing.
See which live patents your product might run into before you take it to market.
Watch a technology area or a competitor and get an email when a new filing matches it.
The options today
USPTO Patent Public Search and Google Patents are free and hold the whole record. They were built for examiners, so you guess keywords and read class codes, and the moment the original inventor used different words than you, their patent never surfaces.
A patent search firm charges $300 to $2,000 a report and takes a few days. The platforms the pros trust, Clarivate and PatSnap, open near $5,000 a seat per year, which is a heavy bill for one idea. PriorScout sits at $39 a month and answers in about a minute.

FAQ
Any public proof that an invention already existed before your filing date. Earlier patents, published applications, papers, products on a shelf. If a patent office finds it, your claims get rejected, which is why a prior art search early is worth the minute.
Those match the words you type. PriorScout is an AI patent search that matches what your invention does, so it pulls filings that describe the same idea in language you would never have guessed, and it hands you a verdict and a report the public sites do not.
Describe it in a sentence or two and run the search. You get the closest existing patents and a read on whether close prior art exists. Before you file something you mean to defend, have a registered patent attorney confirm it.
