I may be missing something, which is usually the case, but didn’t the article say that Shazam was founded in 2002 and this guy didn’t file for the patent until 2005? Seems to me, unless Shazam wasn’t doing what it is doing now back then, that Shazam was 3 years ahead of this guy.
Am I missing something?
You are. It was granted in 2005. The "inventor" submitted it (applied for a patent) in 2000.
