Frequently Asked Questions

What's the difference between a Plant Patent and a Utility Patent for plants?

A Plant Patent (35 U.S.C. §161) protects asexually reproduced plants (excluding tuber propagated plants like potatoes), requires a single claim, and covers the specific cultivar. A Utility Patent can cover sexually reproduced plants, plant parts, genes, or breeding methods, allows multiple claims, and requires enablement across the claimed scope.

Why must I use the RHS Colour Chart instead of generic color names?

The USPTO requires objective, reproducible standards for color description. The Royal Horticultural Society Colour Chart is the industry standard because it provides specific alphanumeric codes (e.g., RHS Red 45A) that eliminate subjective interpretation of colors like 'deep red' or 'light pink'.

Can I file a plant patent if I've already sold the plant commercially?

No. The U.S. has a strict one-year grace period. If the plant was sold, offered for sale, or publicly disclosed more than one year prior to filing, the patent is barred. Additionally, the plant must not have been released under a name that became generic or established prior to the application.

Why is there only one claim allowed in a plant patent?

37 CFR 1.164 specifically limits plant patents to a single claim because the invention is the plant itself as defined by its unique genetic and phenotypic characteristics. The claim traditionally reads: 'A new and distinct [genus] plant named [variety name], as illustrated and described.'
