The patent system is completely and utterly broken.
There are companies (known as "patent trolls" and staffed almost entirely by lawyers) which are filing patents all the time (but never manufacturing any of them), written in the vaguest possible terms, purely with the intention of suing anyone who manufactures something that by any stretch of the imagination could be covered by it. These are called "submarine patents" because they pop up by surprise. In reality it
discourages anyone from inventing anything or designing anything new, unless they have the power of a very large corporation behind them prepared to fight the patent troll in court. Searching for existing patents that might affect your own invention is a massive and almost certainly inconclusive task.
On the other hand, large manufacturing corporations are patenting every idea they can think of as "defensive patents". It is comical to see what some companies (Apple and Microsoft for example) do patent; Apple's rounded corners was one that happened to come to court, and about 10 years ago there was a guy who patented the wheel just to show how silly the system has become.
The attitude of the patent offices is to rubber stamp everything put before them (they are overwhelmed with the volume of it) and let the companies involved fight it out in court. I'm getting off-topic though.
