Widdowson is a specialist. He's one of 10 reverse-engineers working full time for a stealthy company funded by some of the biggest names in technology: Apple, Microsoft, Research In Motion, Sony, and Ericsson. Called the Rockstar Consortium, the 32-person outfit has a single-minded mission: It examines successful products, like routers and smartphones, and it tries to find proof that these products infringe on a portfolio of over 4,000 technology patents once owned by one of the world's largest telecommunications companies.
