Meanwhile, Schmeiser became a popular figure among those opposed to genetic engineering. He accepted speaking engagements around the world. Schmeiser continued to face threats and harassment from Robertson Investigations; a firm hired by Monsanto to enforce their patent. Ultimately, in a split decision from the Supreme Court, Schmeiser won a 9–0 ruling that he did not have to pay Monsanto their technology-use fee, damages, or costs. The court ruled that Schmeiser did not receive any benefit from Monsanto's technology, but still ruled in a 5–4 decision that Monsanto had a valid patent, and that unintentional possession didn't matter, thus Schmeiser infringed on the patent.
