And the loser is...
Of course, the biggest looser from all this and similar nonsense is you and I - the end users/consumer. It means that the products you can buy are not as good as they could be because of the numerous, and often silly, patents that companies hold. A manufacturer often takes the cheaper route (and who can blame them) of working around a patent, rather than buying into it. Of course, the patented method is quite often the best (and often obvious) method, which means the product on the shelf is never quite as good as it could be.
Having worked in the consumer electronics industry for many years, I have seen this happen time and time again.
