Hey there, let's dive into a recent court decision involving FMC Corporation and Natco Pharma. The case revolves around a dispute over a chemical compound used in pesticides.

Background of the Case

FMC Corporation, along with its subsidiaries, holds a patent (IN’645) for a compound called "Cyantraniliprole" used in pesticides. They accused Natco Pharma of violating this patent by making a similar product, "Cyantraniliprole 10.26% OD."

The Legal Battle

FMC asked the court to stop Natco from making the product temporarily, claiming it violated their patent. However, Natco argued that they were using a compound already mentioned in an earlier patent (IN’104), which had expired.

Court's Findings

  • Previous Claims: The court found that the compound in question was indeed mentioned in Natco's earlier patent, IN’104. This means Natco's product wasn't violating FMC's current patent.

  • Specific vs. General: The court noted that IN’104 (specific patent) predicted FMC's IN’645 (general patent), making FMC's patent open to challenge.

  • Gillette Defence: Natco successfully argued that they were using something already known, so they weren't violating FMC's patent.

Balance of Convenience

The court also thought about which side would be more affected. Natco had already started making and selling the product, investing a lot in the process. Since the patent was close to running out, the court felt FMC could be paid money if they won the case later.

Verdict Summary

Judge Mini Pushkarna denied FMC's request to stop Natco, allowing Natco to continue its operations. The decision highlighted the importance of previous claims and the difficulties of proving patent violation when something similar already exists.
