Rob Zenilman submits: Within a specific sector, gross margins can differ dramatically, due to the different nature of their businesses. Among the memory chip manufacturers tracked here, gross margins ranged from 24.8% (STEC) up to 85.7% (RMBS). The companies that have drastically higher gross margin are what I like to call "gross margin kings".
What separates out the companies with the four highest gross margin rates is that they earn money by licensing out their technology. 88% of Rambus' revenue is from licensing, 100% for MoSys (MOSY), 56% for Saifun Semiconductors (SFUN), 100% for Virage Logic (VIRL) and 25% for Staktek Holdings (STAK).

However, having high gross margins is no guarantee of profitability. Of the four companies here with gross margins over 70% (and that derive most of their revenue from licensing) - only Rambus has a positive P/E of 62.84.
