Patent pending
（重定向自Patent marking）
"Patent pending" (sometimes abbreviated by "pat. pend." or "pat. pending") or "patent applied for" are legal designations or expressions that can be used in relation to a product or process once a patent application for the product or process has been filed, but prior to the patent being issued or the application abandoned. The marking serves to notify the public, business, or potential infringers who would copy the invention that they may be liable for damages (including back-dated royalties), seizure, and injunction once a patent is issued.
