There are different kinds of patents, one being design, and slight changes for increased strength etc would not be a valid difference. There is a patent attorney as a member, "AAR????", but he seldom pokes his up anymore. We are wasting our time discussing patent issues, as few vendors take the time and spend the money within 12 months of the item being offered commercially in order to acquire patent rights, nor are willing to spend the money on lawyers shutting down every garage rendition of their product.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
