Why PatentScan
How it works
Describe your invention's key features for a patentability check, or paste a patent UCID for invalidation analysis.
Semantic AI scans millions of patents and non-patent literature, ranking by conceptual relevance — not just keywords.
Receive a structured invalidation report with claim charts, relevance scores, and citations you can use in filings.
Trusted by IP professionals
“As a Senior Patent Analyst, I rely heavily on tools that can dig deep into prior art, and PatentScan has become my go-to. The niche algorithm finds references that other tools simply miss.”
“I've generated about 10 invalidation reports so far. The quality is consistently strong, and the iteration-refine loop lets me zero in on exactly the prior art I need for each case.”
“Patent scan is definitely a valuable tool for patent analysts as well as for researchers. It saves a lot of time and makes patent analysis more efficient.”
Learn the concepts
Interactive explainers that show exactly how modern prior-art search and invalidation work — type in your own example and watch.
Watch a plain-English invention become a ranked list of prior art — and see why keyword search misses references semantic search finds.
Break a claim into its elements and build an invalidity claim chart, element by element — §102 anticipation vs §103 obviousness.
The vocabulary gap, the prior-art funnel, the classification tree, and more — the clearest explanations of these ideas anywhere.
Patentability searches and invalidation reports in minutes, not weeks. Know if your invention is patentable before spending $5,000+ on prosecution.
Perfect for one-off searches and quick validation.
Start with the basics:
Best for founders and solo operators filing regularly.
Everything in Starter, plus:
For teams filing multiple patents. Collaborate, track, and scale.
Everything in Pro, plus:
For IP firms and large organizations with advanced needs. Tailored to your requirements.
Everything in Growth Team, plus:
1 analysis = a patentability search, an invalidation report or an infringement report. Prices in USD. Annual billing shows the monthly equivalent.
💡 Filing a patent costs $5,000–$15,000 in legal fees alone. A $19 patentability check tells you if it's worth pursuing before you spend a dime.
FAQ
PatentScan uses semantic AI embeddings to understand the meaning behind your invention, not just its keywords. This lets us surface conceptually similar patents even when they use completely different terminology — the kind of prior art that trips up traditional keyword searches and expensive manual reviews.
Enter patents in UCID format: CC-XXXXXXXX-KK (e.g., US-11907553-B2). That's country code, patent number, and kind code separated by dashes. US utility patents use kind codes like B1, B2; published applications use A1. You can find the UCID on the patent's cover page or from Google Patents.
Most analyses complete in 3–10 minutes depending on the complexity of the patent and search depth selected. Starter-tier Standard analyses are fastest; Growth Team Advanced searches take a bit longer due to broader source coverage and deeper claim mapping.
Yes. All data is encrypted in transit and at rest. We do not use your invention descriptions or patent queries to train our AI models, and we never share your data with third parties. Enterprise customers can request a signed NDA and our full SOC 2 Type II report.
A Patentability Search takes your invention description and finds prior art that could block a new patent application — ideal for inventors and R&D teams before filing. An Invalidation Report takes an existing patent number and finds prior art that could be used to challenge or invalidate that patent — ideal for litigation support, freedom-to-operate analysis, and IPR proceedings.
Yes — your first analysis is completely free, no credit card required. Sign up, run your search, and get a full report before deciding on a plan. After that, pay-as-you-go starts at $19 per analysis.
