If you're familiar with my comment history, I'm actually opposed to the patent system, and most of the copyright system. Yes, in the past I made money selling copyrighted software. I continue to write software, making it freely available, and made no attempt to patent the innovations in it.

Keep in mind that phones at the time did not have side buttons, the side buttons on my iphone are ergonomically unsuitable for use as a morse key, are in the wrong location for it, and there wasn't an app store then.

I've also had many people copy my ideas, steal my software, and claim they invented them and wrote them. It gets a little tiring. I've used a registered copyright to stop some of those claims. Having a patent means I can solidly claim originality.

I also hoped someone would see the patent and want to implement it, as I was focused on other things.
