Analysis

Examiner Wenren Chen operates in Tech Center 3600 and Art Unit 2644, where 217 cases have been resolved. The data reveals a challenging allowance rate of 15.2%. This 15.2% rate suggests that the majority of applications face significant hurdles during examination. Additionally, the median days to allowance for successful cases is 1342, indicating a long and persistent effort is required. This 1342-day timeline should be factored into the strategic planning for any application in Art Unit 2644.

The interview lift is 28.7%, which offers a potential path to improve the 15.2% baseline. This 28.7% lift indicates that direct engagement with the examiner is more effective than relying solely on written responses. Practitioners should consider scheduling an interview early to navigate the 1342-day median pendency more efficiently. In Tech Center 3600, the 28.7% lift is a critical tool for overcoming the low initial allowance probability.

With 217 resolved cases, these statistics provide a clear picture of the examiner's rigorous standards. The 15.2% allowance rate and the 28.7% interview lift are the most important factors for applicants to consider. The 1342-day median to allowance reflects the complexity of the cases handled in this unit. Practitioners should prepare for a detailed and potentially lengthy prosecution when assigned to this examiner.
