I applied for a Business Process Patent years ago because it appeared to be a way to protect a business model that larger, more aggressive competitors could co-opt. It wasn’t. I never knew why, and never got a straight answer from the patent attorneys I dealt with, but it was clear that large aggressive corporations could get business process patents and I could not.
Ten-plus years later, we see the USPTO revising how it awards such patents. We have discussions of how the changes might effect things like Google’s patent on PageRank. Man, if I ever needed a student of the law who could also explain things in the good English that we search people understand, I need one now.
