Not legal advice. PatentDistance is an engineering screening aid. It maps your design against claim limitations and scores distance. Only a qualified patent attorney can give an opinion.
Free plan: 3 checks/day, screens the first 3 claims, paid plans screen all 20 claims of the patent
How to get good results
Claims: paste the full Claims section starting at claim 1. Keep the numbering (1. 2. 3.). Strip page numbers, column text, and paragraph tags like [0031]. Claim 1 is the broadest and carries double weight, so never leave it out. Free plans screen the first 3 claims, paid plans all 20; the rest are skipped, not ignored.
Your description: name mechanisms, not goals. "A USB-powered fan pulling air through a perforated aluminum deck with an adjustable-angle stand" scores far better than "a laptop cooling product". For software, name the architecture: cache, API endpoint, database, protocol, offloading, model.
Completeness: the engine flags a description that skips limitations the claims clearly cover (mixed evidence). If a verdict reads likely clear (review), add the missing detail rather than celebrating.
Step 2, design-around brainstorm: after a check scores your design, engine-verified alternatives that break the closest limitations appear here. Run a check above to start.
