Analysis

Igor N. Borissov operates in Tech Center 3600 and Art Unit 3626. Borissov has handled 924 resolved cases and has a low allowance rate of 28.5 percent. This figure indicates a very rigorous examination process for applications in business methods and data processing. Practitioners should be prepared for a difficult path to grant with a low probability of success.

The interview lift is 41.7 percent, a high figure that suggests interviews are an essential tool for overcoming rejections and securing an allowance compared to cases without them. This indicates that direct communication is highly effective. The median days to allowance is 1393, reflecting a long and difficult path to grant for successful applications from the initial filing date.

Top companies include Charge Fusion Technologies LLC, NEC Corporation, and Koninklijke Philips N.V. Firms like RowanTree Law Group, PLLC and Troutman Pepper Locke LLP are active in this art unit. These metrics emphasize the necessity of direct communication in this challenging technology area, where the 28.5 percent allowance rate is a major factor.
