Once I’ve filed a patent application (e.g., provisional patent application, nonprovisional patent application) on EFS-Web and received an acknowledgment receipt, can I apply the term “Patent Pending” to products for which the patent application has been filed?

After a filed provisional patent application is accorded a filing date, one is permitted to apply the term "Patent Pending" to products for which the patent application has been filed. After a filed nonprovisional patent application is accorded a filing date, one is permitted to apply the term "Patent Pending" to products for which the patent application has been filed as long as the nonprovisional patent application is pending.
