At first glance, Wesley & McCain looked like an established Pittsburgh law firm, filled with eager professionals. That's what its website showed at least, complete with a group photo.

But while the attorneys were real, Wesley & McCain was a fiction. The photo actually showed lawyers from Brydon, Swearengen & England in Missouri, whose images had been used to create a website for the fake firm. The counterfeiter had used a real Pittsburgh firm's street address too—that of Robb Leonard Mulvihill, according to a CNBC news report.

The bogus site was discovered after Wesley & McCain sent Amazon.com a letter alleging it was selling a patent-infringing product, and Amazon removed the item. It's unclear exactly what motivated the scheme; the real firms, Brydon Swearengen and Robb Leonard, did not respond to requests for comment.
