Completing the Form: Proper Preparation of IDS Forms

The Information Disclosure Statement (IDS) is a crucial document in the patent application process that allows the applicant to disclose any prior art references known to them. Proper preparation of IDS forms is essential to ensure accurate and complete disclosure of relevant prior art. In this article, we will guide you through the steps for completing IDS forms effectively.

1. Understand the Purpose of IDS Forms

Before preparing an IDS form, it’s important to understand its purpose. The IDS is used to disclose any prior art references that may affect the patentability of the invention. By providing this information, the applicant fulfills their duty of candor and good faith to the patent office, ensuring that the examiner has access to all relevant prior art during the examination process.

2. Identify Relevant Prior Art

Thoroughly research and identify any prior art references that are relevant to your invention. Prior art includes any publicly available information, such as patents, patent applications, scientific publications, technical articles, and even publicly accessible websites. Carefully review each reference to determine its relevance to your invention and its potential impact on patentability.

3. Evaluate Materiality and Submitting Requirements

Not all prior art references need to be submitted through an IDS form. Only material references that are reasonably believed to be relevant to the examination of the patent application should be included. Evaluate the materiality of each reference by considering its similarity to your invention, the potential impact on patentability, and any inconsistencies it may create with the claims.

Additionally, familiarize yourself with the specific submission requirements of the patent office where you are filing your application. Each office may have different rules regarding the format, content, and timing of IDS submissions. Adhere to these requirements to ensure compliance and prevent any delays or rejections.

4. Complete the IDS Form

When completing the IDS form, provide accurate and detailed information for each prior art reference. Include the full bibliographic details of the reference, such as the title, author, publication date, and relevant pages or figures. Clearly indicate the relevance of each reference to your invention and the specific aspects it addresses.

5. Create an IDS Disclosure Statement

Along with the IDS form, include an IDS Disclosure Statement that explains the relevance of each prior art reference to your invention. Describe how each reference relates to the claims of your application and the specific features it discloses. Be concise, but provide enough information to establish a clear connection between the prior art and your invention.

6. Keep Track of IDS Updates

During the prosecution of your patent application, you may come across additional prior art references that need to be disclosed. Maintain a diligent and ongoing monitoring process to identify any new relevant references. Timely update your IDS form and submit the necessary amendments to ensure that the examiner has the most up-to-date information throughout the examination process.

7. Seek Professional Assistance

Preparing IDS forms can be complex, especially for complex inventions or applications with extensive prior art. Consider seeking professional assistance from a patent attorney or agent who specializes in patent prosecution. They can provide guidance, conduct thorough prior art searches, and ensure that your IDS forms are accurately completed and submitted.


Proper preparation of IDS forms is crucial for fulfilling your duty of disclosure and ensuring that the patent examiner has access to all relevant prior art during the examination process. By understanding the purpose of IDS forms, identifying relevant prior art, evaluating materiality, completing the forms accurately, and seeking professional assistance when needed, you can effectively disclose prior art and enhance the examination of your patent application.
