Analysis

Grace NMN Rozanski is an examiner in Art Unit 3791 of Tech Center 3700. The examiner has managed 86 resolved cases, resulting in an allowance rate of 60.5 percent. This rate indicates a moderate level of success for applications in this technology area, suggesting that the examiner is thorough but fair. The 86 resolved cases provide a clear view of the examiner's standards and the consistent application of patentability requirements during the prosecution process.

The interview lift is 20.7 percent, suggesting that interviews are a beneficial part of the prosecution strategy. Engaging with the examiner may help in clarifying complex technical issues and moving the application toward a grant, as shown by the 20.7 percent lift in success. This indicates that the examiner values the additional context provided during oral discussions. Practitioners should consider scheduling an interview to address rejections and align on the scope of the claims more effectively than through written responses alone.

The median days to allowance is 1510. This is a long duration, reflecting a protracted prosecution process that requires significant persistence. The 1510-day median is an essential metric for managing the expectations of stakeholders and for planning the long-term protection of intellectual property. It underscores the importance of a proactive and patient strategy throughout a prosecution cycle that may span several years before reaching a final grant decision.
