How a specific does a patent have to be?

質問

You often hear that for technology to be patentable it has to be sufficiently distinct from the technology already in the market. But how specific does a patent have to be? For instance, there is no one single smartphone patent, but many. How do I know if the technology I want to patent is too broad?

It must be specific enough to enable "one of skill in the art" for the field of the invention to understand and utilize the invention. You must do research on the "prior art" (i.e. existing patents and publications) to see if your invention or something similar has already been disclosed. You should hire a patent attorney as part of that effort.
