LONDON, April 17, 2013 /PRNewswire/ --

In 2012, patents on several blockbuster drugs expired, leading to increasing competition from generic drug manufacturers. Major drug manufacturers are likely to see more patent expirations in 2013. As generic competition is expected to continue rising, major drug manufacturers will have to boost their product pipeline. One way of doing this will be by collaborating with or acquiring biotechnology companies that have developed or are developing potential blockbuster drugs. Among the biotechnology companies that major drug manufacturers can look at are Arena Pharmaceuticals Inc. (NASDAQ: ARNA), Celgene Corporation (NASDAQ: CELG), Incyte Corporation (NASDAQ: INCY), Spectrum Pharmaceuticals Inc. (NASDAQ: SPPI), and Geron Corporation (NASDAQ: GERN). Biotechnology stocks ended mostly higher on Tuesday, tracking gains in the broad market.
