Can someone apply for a patent while a product is under pending patent?

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
