Submission Dates

Latest Date for Responses

For a submission to be accepted, the document must be dated on or before the Latest Date for Responses (LDR). The relevant date depends on the type of submission.

For non-patent literature, the relevant date is the publication date.

For patents, the relevant date may vary depending on the requirements of the search and the needs of the client. The relevant date for each patent type may be one of these three dates:

  • Filing Date – This is the date when the application for the patent was filed.
  • Publication Date This is the date when the patent document was first made available to the public.
  • Priority Date – This is the earliest date to which a patent can claim priority. For example, this may be the filing date of a provisional application on which the patent is based or the filing date of a parent application for a patent that is a continuation.

Please refer to the Study page to see the relevant date corresponding to each type of patent.

Preferred Latest Date for Responses

In a few Studies, there is a Preferred Latest Date for Responses (PLDR) that is earlier than the LDR. We will accept submissions dated after this PLDR, as long as they are still dated on or before the LDR. You have a higher chance of winning the Reward, however, if you submit an in-scope document that is dated on or before the PLDR.

Submission Dates for NPL

Monthly periodicals and some other NPL do not provide exact publication dates. For such documents, you may select “unknown” in the corresponding date field(s) of the submission form if the day and/or month is not provided. When “unknown” is selected for the day or the month, the system will assign the first day or the month by default. The Review Team reserves the right to validate this date on a case-by-case basis.

Before submitting NPL, please make sure that the document in its original form clearly shows the publication date. Please do not alter or modify the document by typing the publication date onto the document. You may, however, provide proof of the publication date as follows:

Ways to provide proof of the publication date

  • The publication date is indicated in the document in its unaltered form.
  • The submitted PDF file includes the original document merged with a screen shot or additional page showing the bibliographic information or copyright page with the publication date.
  • Typing the date directly onto the document is NOT an acceptable way of providing proof of the publication date.
  • Providing only a URL of a webpage is also NOT an acceptable way of providing proof of the publication date for any prior art submission.  Instead of (or in addition to) providing the URL, supplement the document with a screen shot or an additional page that shows the section of the webpage that includes the publication date.
  • If your prior art submission itself is a webpage, please provide a PDF copy of the webpage AND the URL.  As in other document types, the publication date must be indicated in the PDF copy.  If the publication date is not included in the original form of the webpage, you may use the Way Back Machine to authenticate the date.  In addition to providing the relevant Way Back Machine URL in the field provided in the submission form, supplement the PDF copy with a screen shot or an additional page that shows the relevant Way Back Machine page.

Sources to verify the publication date

  • The document in its original/unaltered form
  • DOI of the document
  • Bibliographic information on a database
  • Wayback Machine (for webpages only, as described above)
  • Dates from search engine results will NOT be accepted.

The publication date is always required even if the Study has no LDR requirement.
