Pioneer Overseas Corp. has accused Hyderabad-based Kaveri Seeds of copying the gene structure of a variety of corn developed by the Iowa, US-based firm. [...] The plant variety registered by Kaveri Seeds was developed from its own research, said chief scientific officer Malla Reddy. “We have now moved court against the registry’s decision to allow Pioneer Overseas to oppose our registration by extending the time for such a move,” Reddy said. Pioneer Overseas asked the registry in early September for more time than is stipulated in such cases to file its opposition to Kaveri Seeds’ plant after it allegedly found the Indian company’s research was identical to its own.
