Chapter 6: Patent Applications on Rice

This chapter shows the results of MEGABLAST analyses of sequences that are recited in the claims of U.S. patent applications. The sequence database used in this analysis contains sequences from all applications, regardless of whether they are abandoned or pending.

Patent applications usually become publicly available 18 months after they are filed, and therefore, our analysis will not include the most recently-filed patent applications. However, we will be updating the tables periodically with new patent data as we acquire it.

Analyses of patent applications differ from those of granted patents because applications often claim many nucleotide and amino acid sequences, in some cases tens or hundreds of thousands, for example, in bulk sequence applications. If granted however, they are likely to claim only one or two of these sequences (read ahead for a description of how many sequences are examined in a U.S. patent application). For this reason, we have not performed a detailed analysis of the sequences mentioned in the claims of pending U.S. patent applications, since most of them will not end up in the claims of a granted patent.


We identified 313 U.S. patent applications that recite rice sequences in the claims. Of these, 30% are abandoned. We also found that approximately 74% of the rice genome is recited in the claims of U.S. patent applications.
