Design Search
Upload drawings of your product design and see which US design patents look closest.
Turnaround: usually within one hour; sometimes up to 24 hours. Pay per search, no subscription.
Who it is for
- Product designers and industrial designers about to file a design patent
- Consumer-goods and hardware startups checking a shape before tooling
- Furniture, packaging and accessory makers
- Amazon and e-commerce sellers with a custom product shape
- Anyone who wants to know what a design patent attorney would find in the first hour
What it does
You upload clear drawings or images of your design and a short description. Primoris shortlists US design patents by title keywords and design class, retrieves their drawings and compares them visually with yours. The closest designs get a deeper comparison that notes what an observer notices first, the shared features and the differences. Visual matching across the full drawing archive is being rolled out; today the always-on text and class shortlist feeds an AI visual comparison of the closest candidates.
Key capabilities
- US design patents 1976 to present, shortlisted by title keywords and design class
- AI visual comparison of your drawings with the drawings of the closest candidates
- Deep comparison of the closest designs: shared features, differences and an automated similarity score
- Similar products on the web, labelled unverified
- Candidates whose drawings could not be retrieved are listed as text-only, not hidden

- Foreign designs (EUIPO, Hague/WIPO, Japan, Korea, China)
- Products that are not shown in patent records or on the web
- Look-alike designs filed under unrelated titles and classes, and designs outside the closest candidates compared
- Legal findings. Similarity scores are automated visual-screen scores, not statements about infringement or whether a design patent would be granted
- Legal advice, or any guarantee that a design patent will be granted
Risk rating explained
Every report opens with a Risk Factor Rating. The words, not the colour, carry the meaning. The rating is a screening aid, not a legal finding.
- HIGH RISK
- An earlier design looks very close to yours overall. Worth a careful look with an attorney.
- MEDIUM RISK
- An earlier design shares several features with yours, with noticeable differences.
- LOW RISK
- No close design was found among the candidates compared. Designs filed under unrelated titles and classes can be missed.

Frequently asked
- How does the visual comparison work?
- Your drawings are compared by AI with the drawings of the closest candidate design patents, which are shortlisted by title keywords and design class. The closest few get a deeper comparison that lists shared features and differences. Visual matching across the full drawing archive is being rolled out.
- What is the similarity score?
- An automated visual-screen score for ranking. It is not a legal finding and not a statement about infringement or whether a design patent would be granted.
- What should my drawings look like?
- Clean, well-lit images or line drawings that show the shape from one or more angles. Up to six PNG, JPG or WEBP files, 10 MB each. Blurry or cluttered images compare less well.
- Are foreign designs covered?
- No. Only US design patents are searched. EUIPO, Hague/WIPO, Japanese, Korean and Chinese designs are not.
- Can a similar design be missed?
- Yes. A look-alike filed under an unrelated title and class can fall outside the shortlist. Each report says how many designs were considered and how many were compared.

Primoris reports are automated screening reports. They are not legal advice and not an attorney opinion, and no attorney-client relationship is created. A gap in the results does not prove that nothing exists. Talk to a registered patent or trademark attorney before filing or relying on a report.
