In some countries or regions, early publication of a patent application can shorten the patent application cycle. However, this is not the case for U.S. patent applications.

To understand why, we need to discuss the relationship between the publication and substantive examination of U.S. patent applications.

PART 1: The Relationship Between Publication and Substantive Examination of U.S. Patent Applications

In some countries, an application must be published before it can enter substantive examination, establishing a sequential order between publication and examination. Consequently, early publication can shorten the entire application cycle in these countries.

In the United States, the publication and substantive examination of patent applications are two independent processes, with no sequential relationship between them.

According to U.S. patent law, the standard publication time for a patent application is 18 months from the filing date (or the priority date, if applicable).

In the U.S., the publication of a patent application does not indicate that the application will immediately enter the substantive examination phase.

PART 2: Factors Influencing the Timing of Substantive Examination of U.S. Patent Applications

In the U.S. patent application process, the USPTO (United States Patent and Trademark Office) reviews the completeness of the application documents. Each patent application is assigned a unique application number and a corresponding classification number, after which it is allocated to an examiner for review.

This means that the start time of the substantive examination phase varies based on the specific circumstances of each application. The substantive examination officially begins only after the application documents have been confirmed to be complete and accurate, and it is not determined by the publication date.

According to the latest data, the average time for U.S. invention applications to receive the first Office Action (OA) is 19.4 months.

PART 3: Early Publication Only Advances the Publication Date

When applying for a U.S. patent, if an applicant requests early publication, the publication date will indeed be advanced.

Typically, once the preparatory procedures (such as fee payments) are complete, the application will enter the publication process, with the publication date occurring approximately 14 weeks thereafter, which is significantly earlier than the standard 18-month publication period.

Of course, if there are issues with the application documents and a notice of correction is issued, this timeframe may be slightly extended.

PART 4: The Impact of Early Publication on U.S. Patent Applications

Does early publication have no other effects if it cannot shorten the cycle from submission to grant of a U.S. patent application?

Certainly not.

The most crucial function of early publication for U.S. patents is that it can serve as prior art in the examination of the novelty of competing patent applications, potentially influencing the examination outcomes of those applications.

Additionally, early publication of a U.S. patent application can, to some extent, provide earlier warning to competitors of potential infringement, allowing the applicant to gain provisional protection sooner.

However, this also gives competitors more time to prepare to design around the patent.

Conclusion

In summary, early publication of a U.S. patent application does not accelerate the examination process. Therefore, applicants should be mindful of this fact and consider multiple factors when deciding whether to request early publication. If you have any questions, please feel free to leave a comment.
