Patent Applied For.
Absolutely. The term "patent pending" applied to a product has no legal ramifications. It's just advertising that they are trying to patent the technology that went into the product. Only an issued patent is enforcable. Some products will print patent numbers on their packaging if patents have issued for the technology. You cannot get a patent for something you didn't invent though. Filing a patent application involves signing an oath, and lying under oath is perjury. Patent pending can only be displayed on the product/services, when you have applied for a patent. So, there is no question of applying for a patent while a product is under pending patent. http://indiapatents.blogspot.com

A patent is a grant from a patent office, such as the United States Patent Office. "Patent Pending" is a phrase that an application for a patent has been filed and is in some stage in the process of obtaining a patent. Thus, a patent can be presently enforced while a patent that is merely pending is unenforceable but can mature into a patent that can be enforced. Once the pending patent matures, the patent owner can sue for back damages or reasonable royalties starting from the filing date of the patent.

Thomas Welsh was not the inventor of the skateboard. He was simply a man who saw that there was no patent and wanted to capitalize on that fact, so he applied for the patent. Going back as far as 1962, there was a patent for a "child's coaster" by A.C. Boyden.
