While patent examiners can search this site, the best way to ensure they see your discovery is to submit it using the [USPTO electronic filing system](http://www.google.com/url?q=https%3A%2F%2Fefs.uspto.gov%2Fefile%2Fportal%2Fefs-unregistered&sa=D&sntz=1&usg=AFQjCNFslPS24hlRRAPWF5O6v21-KeLr3Q).  

If you've proposed useful prior art at Ask Patents, there's a good chance a USPTO patent examiner will find that prior art when he or she examines the application in question.

**However, to be sure that your prior art counts, submit it to the USPTO.**

If you’re going to make a submission, make sure it counts. It’s important to only submit art that seems likely to be relevant. (If you’re not sure, ask a new question about the relevance here on $SiteName.) The goal is to make a meaningful contribution, not spam a patent examiner’s inbox. You can only submit **3 examples of prior art per patent application** before the USPTO charges you a fee. 

**Heres how to make a submission directly to the USPTO:**


(This looks long, but we made it step-by-step to ensure that experts and inventors who aren't lawyers or patent experts can actually make a difference.)

1) Sign in as an Unregistered eFiler here: https://efs.uspto.gov/efile/portal/efs-unregistered

2) Select "Existing application/patent"

3) Select "Third-Party Preissuance Submission under 37 CFR 1.290"

4) Enter the Application Number and the Confirmation Number (found at the application's page within the [USPTO's Public PAIR system][1]) and hit "Submit."

5) Submit prior art: If your prior art is a US patent, submit it at the top section of the form. Sections follow for prior art in the form of patent applications, foreign patents & foreign applications, and non-patent applications. Be sure to include a concise description of relevance for each example of prior art submitted. 

Also, at the beginning or end of each description of relevance, include your Ask Patents user name in the format: “Ask Patents: username.” Doing so will make sure you get credit if your prior art is accepted and help us measure the success of Ask Patents.

See below for submission requirements for each type of prior art.

**US Patents:**
Enter a Patent Number, Concise Description of Relevance, and Kind Code (see here for a list of USPTO Kind Codes: http://www.uspto.gov/patents/ebc/kindcodesum.jsp)

**US Patent Applications**
Enter a Publication Number, Publication date, Concise Description of Relevance, Kind Code, and First Named Inventor

**Foreign Patents and Foreign Patent Applications**
Enter a Patent Number, Kind Code (optional -- see Patent Kind Codes by country here: http://www.delphion.com/help/kindcodes); Applicant, Patentee or First Named Inventor; Concise Description of Relevance; Country Code (see Country Codes here: http://www.uspto.gov/patft/help/helpctry.htm); Publication Date; and mark whether or not there is a Translation Attached (Translations must be attached for non-English language foreign patents. Machine translations may be submitted.)

**Non-Patent Publications**
Enter the Author, Title of the Publication, Pages Submitted, Publication Date (MM/DD/YYY), Publisher, and Place of Submission (enter all that apply); a Concise Description of Relevance; and mark whether there is a Translation Attached or Evidence of Publication Attached. 

Note: A URL is not an acceptable form of prior art. Information conveyed on a website can change from moment to moment, making date of publication difficult to determine. If your prior art is web-based, please be sure to attach a screenshot at the “Add Attachments” screen.

6) Request Non-Compliance Notification
If you'd like to be notified if your prior art submission is non-compliant with third-party preissuance submission requirements, check the box and enter your email address. If you receive a notification of non-compliance, start at the top and resubmit your prior art with all requirements fulfilled.

7) 3 is Free, 4 is More
You can submit 3 examples of prior art per application for free. If you want to submit more than 3, you must pay $180 for up to 10 examples of prior art per patent application. In the section titled “Statements,” mark whether you are exempt from payment or not. Then confirm your prior art submission by entering your signature (your name bound by forward slashes) and your name, and click "Continue."

8) Add Attachments
Upload foreign patents, translations, screenshots of pior art, and other relevant documents at the “Attach Documents” screen. Index your attachments properly by selecting “EProcessing” in the “Category” drop down menu. Select the appropriate description for your attachments in the “Document Description” drop down. Click “Upload & Validate” for every attachment and click “Review” when all documents have been uploaded.

9) Review & File
Click "File Third Party Submission" to complete your prior art submission.

**That’s it!** You’ve participated in the examination of a patent application. If your submission complies with the USPTO’s rules, you will be able to track the submission throughout prosecution via the [USPTO’s Public PAIR system][2]. If your prior art is used to alter the claims of an application or reject it outright, you will know at the conclusion of the examination process when a patent for the invention is either granted or denied.

See [here][3] (pdf) for more comprehensive rules about third-party preissuance submissions.
