Built by an Engineer Who's Been Through the Patent Process — 33 Times.

PriorArtCheck.com was built by Cory McCluskey, President of Expertise Engineering — a product development firm in San Diego with 30+ years of experience bringing hardware products to market.

Over 20 years in product development, Cory has been named on 33 patents. He's sat through the patent process from both sides: as the inventor wondering "is this even patentable?" and as the engineering lead watching clients burn through $10,000+ before discovering their idea already existed.

The pattern was always the same: great idea, expensive attorney, weeks of waiting, and too often a report that said "someone beat you to it." The search itself wasn't the hard part — it was the cost and the wait.

PriorArtCheck exists because inventors deserve a fast, affordable way to check before they commit.

What We're Not

We're not a law firm. We don't give legal advice. We don't file patents. And we definitely don't steal your ideas.

We're a search tool built by engineers who got tired of watching good ideas die expensive deaths. Your attorney still does the legal work — you just show up prepared instead of starting from scratch.
