Clearly you have no conception of how product development and engineering work. Nor do you have a realistic idea of what patents are all about. Engineers develop a product under deadline. There is no additional process where lawyers and engineers get together and identify every single possible concept and idea, document that, and check that against a patent data base; such a process would mean product development would take three times as long and cost ten times as much. Many technologists have the same ideas at about the same time and are unaware of each others'; there's no intent to steal, it's just that people have the same ideas at about the same time.
