Another site that’s good for beginners is Google Patents. http://www.google.com/patents
It’s more user friendly than the others and you can find some really fun things there.
Some people even patent things like chip sandwiches and marshmallows! 🙂
The company that I work for does own some patents on some of the technology that we use. Hopefully we will be able to patent some of the designs on our new bed as we have come up with some quite innovative solutions to some of the problems so far.
Patents mean we can protect our design from someone else copying us and stealing our ideas. It can take a lot of time and effort to develop a new design so it would be very disappointing if someone else stole it without doing the same work you had done.
