This piece of legislation made it possible to patent new varieties of plants, excluding sexual and tuber-propagated plants (see Plant Variety Protection Act). In supporting the legislation, Thomas Edison testified before Congress in support of the legislation and said,
- "This [bill] will, I feel sure, give us many Burbanks."
