Goods with elasticities less than one in absolute value are commonly referred to as having inelastic or price insensitive demand. In other words, the proportional change in quantity demanded will be less than the proportional change in price. In this situation, increasing the price will increase the revenue received by the producer of the good, since the revenue lost by the decrease in quantity is less than the revenue gained from the higher price.
