Understanding the Defense of Inequitable Conduct in Patent Law

Definition & Meaning

The defense of inequitable conduct is a legal strategy used in patent law. It arises when a patent applicant makes a significant misstatement or fails to disclose important information to the patent examiner with the intention to deceive. This defense claims that the applicant has violated their duty to act honestly and in good faith. To successfully use this defense, the accused party must present clear and convincing evidence that the applicant intentionally misled the examiner or withheld critical details.

(Hypothetical example) A company applies for a patent on a new technology but fails to disclose prior art that could affect the patent's validity. If another entity later sues for patent infringement, the accused party might use the defense of inequitable conduct, arguing that the applicant intentionally withheld this information to gain an unfair advantage.
