Intellectual Property
To Patent Or Not to Patent? – That is the Question
by Christopher Hirsz

It should therefore be clear that:
* You do not need a patent to make your invention
* Whether you can make your invention depends only on other
people’s patents
* If you get a patent, you can stop others from making the
invention.
So, in deciding whether to try to get a patent, an essential
question to be asked is whether anyone else would want to make
your invention, not whether you want to do so.
