Why may it be necessary to prove the conception date of my invention?
Most of the countries in the World treat the first person to file an invention as the first inventor and owner. The United States does not follow this rule. In the United States, the first to conceive of the idea is the first inventor and may be able to prevail over a later inventor who files first. Congress is considering changing to the more common “first to file” rule.
