It allows applicants who cross-file their patent applications internationally to obtain prior art search results from multiple patent offices at the same time. Currently, the two participating international patent offices are the Japan Patent Office and the Korean Intellectual Property Office.
The CSP is primarily a collaboration between patent examiners in their respective patent offices. After an applicant’s petition to participate in the program is granted, each examiner performs a prior art search and makes an initial determination of patentability. They then exchange their search results with each other, reevaluating their initial determinations in light of the other examiner’s search results. The examiners then exchange office actions with each other, which are then sent to the applicant. See Figure 1 for an overview of the CSP process.
Eligibility requirements for the CSP are as follows:
The program is limited to a maximum of 400 granted petitions per patent office per year.
The CSP, on its face, may seem like a less attractive option for many patent applicants, as more prior art typically means more rejections. However, the USPTO and its partner patent offices “sweeten the pot” for applicants in a number of ways:
Participation in the CSP may also pay dividends later in litigation. One of the primary lines of attack for patent litigators arguing invalidity is to find and introduce new prior art that was not considered during prosecution. While a broader prior art search during prosecution can increase the likelihood of rejections, it can also strengthen the validity of the issued claims.
Is the CSP right for you? When evaluating potential patent prosecution strategies, a data-backed approach is the best way forward. To learn more about how data can help take the uncertainty out of your patent practice, schedule a free demo of Juristat today.
