In Bowman v. Monsanto, where Bowman used Monsanto's patented Roundup Ready seeds and, in violation of the contract provided by Monsanto, kept seeds from his crop to use next year so that the seeds had the genetic composition of the Monsanto seeds. The Supreme Court held that:
 a. Monsanto's patent only extended to seeds it sold so there was no infringement
  b. Monsanto's patented product could be sold with restrictions, which Bowman violated
  c. Monsanto's patent had expired by the time of the litigation, so the case was moot
  d. none of the other choices are correct
