patent act of 1870

Patent Act of 1870. A U.S. statute that shifted the burden of disclosing the exact nature of an invention to the patent applicant by requiring a rigorous listing of distinct claims. • Before the Act was passed, patent claims were less important than the description and drawings, and the scope of the patent grant was often ambiguous.
