A person can apply for a plant patent if he or she has invented or discovered a new, distinct plant, as long as said plant is capable of asexual reproduction. Photographs, permanent water colour renderings, pencil or pen and ink drawings and so forth are acceptable ways of depicting the plant’s appearance. Such renderings must be faithful representations and must include all of the plant’s distinctive characteristics that are capable of being visually represented. Many inventions are better understood with the inclusion of drawings in the patent application.
These drawings comprise the visual disclosure of the patent claim, which is why it is vital that patent drawings be accurately and clearly produced according the specific guidelines included above, as well as the USPTO’s patent drawing rules..
