Can multiple provisional applications be combined into a single non-provisional application?

Yes, multiple provisional applications can be combined into a single non-provisional application. This is particularly useful when an inventor has made improvements or additions to their invention over time. The MPEP 201.04 states:

A nonprovisional application that was filed within 12 months of an earlier provisional application may claim the benefit of that provisional application.

While this quote doesn’t explicitly mention multiple provisionals, the USPTO allows claiming benefit from multiple provisional applications in a single non-provisional application, provided each provisional is properly referenced and the non-provisional is filed within 12 months of the earliest provisional application.
