Patenting Your Invention
Significant changes to U.S. patent laws were put into effect in September 2011. Patent protection is now based on a first to file system, rather than the old first to invent system. We advise all inventors to look carefully at any patent information published prior to September 2011 to make sure such information is still relevant and accurate.
A brief summary of the patent law changes is available here and a more detailed listing of changes is here.
