Key Findings & Recommendations
This design is at extremely high infringement risk. Your storage box — a rectangular transparent body with rounded corners, side handles, and a contrasting colored snap-fit lid — is a ubiquitous patented form. All 36 matched patents scored above 85% similarity (the "Likely Conflict" threshold), and all are currently active/valid.
Specific risk factors:
- The transparent body + opaque lid combination is heavily protected across CN, EU, WO, DE, GB, and ID jurisdictions
- Major housewares companies (EMSA, ABM Italia, Rotho, 茶花) hold multiple overlapping design patents in this exact form factor
- Both "smart association" and "exact match" models flagged the same patents — the visual similarity is confirmed at structural and pattern level
Recommendations:
- Do NOT proceed with this design as-is for any market with active patents (CN, EU, US, DE, GB)
- To differentiate, consider significant changes to at least 2–3 of these elements: body shape/proportions, lid mechanism, handle geometry, surface texturing, corner treatment
- Consult a patent attorney for a formal freedom-to-operate opinion if you want to proceed with any variant of this rectangular storage box form
