Easily, given the broken and outmoded state of the patent process.
This patent will probably not survive a challenge, though.

Specious patent claims are the only profit growth center left in the
industry. Recent examples are the JPEG claim (could go either way,
frankly), SCO's Linux claim (SCO unlikely to win), that little
company's claim against Microsoft for security services (likely to be
quashed on appeal), Microsoft's patent on interactive TV (likely to be
upheld), etc.
