This examiner grants 76% of resolved cases
Darrell Christopher Ford is a patent examiner in Tech Center 3700 and Art Unit 2831. He has reached a resolution in 588 cases. The data shows an allowance rate of 76.2 percent for these applications. This percentage indicates that more than three-quarters of the cases assigned to him result in a patent grant. Practitioners can use this 76.2 percent rate to gauge the generally positive outlook for applications in this technology area.
Interviews appear to be a highly effective strategy for this examiner, as shown by an interview lift of 39.5 percent. This metric indicates that direct communication is associated with a very large increase in the probability of allowance. An interview lift of 39.5 percent suggests that verbal negotiation is a critical tool for overcoming rejections and moving an application toward a grant. Practitioners should strongly consider scheduling an interview early in the process.
The median days to allowance for successful cases is 966. This duration represents the middle value of the time taken from filing to the issuance of a patent. A median of 966 days provides a specific timeline for applicants to consider when planning their prosecution strategy. These metrics are based on 588 resolved cases, offering a data-grounded perspective on the examiner's historical prosecution patterns and efficiency.
