Analysis

Nelson M. Rosario is an examiner in Art Unit 2617 of Tech Center 2800. The examiner has a total of 852 resolved cases and an allowance rate of 86.0 percent. This high allowance rate, combined with a large volume of 852 cases, indicates a very predictable and favorable environment for applicants. The 86.0 percent rate suggests that the examiner is highly efficient in identifying patentable subject matter and moving applications toward a grant.

The interview lift is 6.3 percent, which is a modest but positive indicator. While interviews are helpful, the high baseline allowance rate suggests that many applications are successful even without direct oral advocacy. The 6.3 percent lift implies that while an interview can provide a slight advantage, the examiner's general receptiveness is the primary driver of success. Practitioners should still consider interviews for complex cases, but they may not be as critical here as they are with other examiners.

The median days to allowance is 704. This is a relatively fast timeline, suggesting that the examiner processes applications efficiently, leading to quicker grants for successful applicants. The 704-day median is an excellent benchmark for applicants who prioritize speed in their patent strategy. It allows for a more rapid transition from the application phase to the enforcement or licensing of granted patent rights, providing a competitive advantage in the marketplace.
