September 9, 2015 by James Yang

Under current U.S. patent laws, the first inventor to file (FITF) a patent application on an invention is awarded the patent.  This means that if two individuals separately file patent applications on the same idea, then the person who first filed its patent application in the U.S. Patent Office will be awarded the patent.  The Patent Office merely looks to the filing dates of … [Read more...]

Can a confidentiality agreement protect me like a patent application?

September 3, 2013 by James Yang

Good question.  The bottom line is that a contract (i.e., confidentiality agreement or non-disclosure agreement) and a patent application protect your interests in different ways.  Hence, the recommended course of action is to do both (1) file a patent application, and (2) have the investors and licensees execute a confidentiality agreement to protect yourself. If you don't … [Read more...]

File patent application prior to disclosure due to first to file rule

July 31, 2013 by James Yang

Inventors are not required to file a patent application before marketing their invention (i.e., product or service) to others. However, doing so is not the recommended course of action because the inventor could lose their patent rights due to the first to file rule.
