These include cultivated sports, mutants, hybrids, and newly found seedlings, other than a tuber-propagated plant or a plant found in an uncultivated state.

Examination of a Plant Patent application
Plant patent applications are subject to the same examination process as any other U.S. application. All plant patent applications need to satisfy the requirements with respect to patentable subject matter, utility, novelty, unobviousness, disclosure, and claim specificity requirements. The claim in a plant patent application must be directed to the "new and distinct variety of plant." The examiner conducts a prior art search before issuing an Action. Sometimes, a report may be obtained from the Agricultural Research Service, Horticultural Research Branch, Department of Agriculture verifying as to whether the plant variety discovered is new and distinct over known plant varieties.
