What are the consequences of not submitting an Application Data Sheet (ADS) with a patent application?

While submitting an Application Data Sheet (ADS) is not mandatory for all applications, there can be consequences for not including one. According to MPEP 601.05(a):

If an application is filed without an application data sheet, the applicant will not have the benefit of:

• The filing date of any provisional application;
• The filing date of any non-provisional application;
• The filing date of any international application;
• The 35 U.S.C. 119, 120, 121, 365(c), or 386(c) priority claim; and
• The foreign priority claim.

These benefits can be crucial for establishing priority dates and protecting your invention. Without an ADS, you may need to submit additional paperwork later to claim these benefits, which could potentially lead to delays or complications in the application process.
