Green Mountain Coffee Roasters’s K-Cups runneth over, even after patents on its single-serving pods expired last September. About 90% of the coffee purveyor’s revenues came from single-cup brewers and K-Cups in 2012, and shares plummeted ahead of the patent expiration. But if investors worried about cheaper generics, they needn’t have. So far, Green Mountain’s customers have proved to be brand loyalists. Sales in the third quarter remained robust, increasing 18% year-on-year.

Even though the company has plenty of business to keep its bean counters busy, Green Mountain is consistently looking for fresh product ideas. Earlier this year, it announced plans to increase its presence (which it estimated to be about 10%) in workplace break rooms. A larger version of its K-Cups, designed for offices, will soon be on the market. The new Keurig BOLT is designed to brew eight cups in about two minutes. --S.G.
