PEND. The full text is Patent pending, sometimes abbreviated as PAT. PENDING, or marked as DESIGN PAT. PEND. After the jewelry design is completed, it cannot be protected by law for a while. In order to protect the hard work, the manufacturer will submit a patent application and mark the jewelry with PAT. PEND. means "patent application in progress." After all, it takes several months to submit for review to approval, so it is better to indicate it first.
