A few years ago, I worked at a very big international company. I was doing R&D in the user interaction field and I had very friendly colleagues: the dream job.
At some point, I had what looked like a good idea: make our user's life easier by predicting his input thanks to multi-modal sensors and a learning algorithm. I know it sounds crazy but it was not a lot more than customizing the Bayes algorithm.
After building a very basic prototype, it turned out that it was a very good idea. My prototype was able to predict more than 90% of our test situations. And the remaining 10% was not worse than before.
For the young and naive innocent I was, the next step was to get more funding in order to build a real life prototype before putting that feature into our product. But, as every big corporation, my employer had rules. One of them being "patent it first".

If you are reading this blog, chances are that you think patents are evil, that they are impending innovation, that they are a very bad thing for our economy and are killing kitties.
After working with patents, I can ensure you it's not. It's even worse than that. It is worse than everything you can possibly think of. Let me share my experience with you.
I don't pretend to hold the truth. I'm not a lawyer. The following is only how I was told and taught to work with patents.
