The Norwegian Johan Vaaler is usually called the inventor of the paper clip. Norway had no patent office, so he filed an American patent for a set of square and triangular clips. That was in 1901. And maybe it was the first paper clip patent.
The type of wire paper clip that is usually used was never patented. It was first made by The Gem Manufacturing Company sometime during the 1890s. The first time Gem was mentioned was in 1883, but historians do not think this is when they began making paper clips.
