Some main features of new US patent reforms
First to File
The biggest change to US patent laws, and certainly the most discussed, is the fact that the United States has now converted from a first to invent system to a first to file system. Saying that we have a first to file system, however, might be a little misleading given that the term “first to file” has certain international meanings that will not apply.
A traditional first to file system is one that demands absolute novelty in order to obtain a patent. A traditional first to file system means that if there is a prior use or publication of information relating to the invention no patent can be obtained. That, however, is not what the US first to file system mandates.
