For the last four years in a row, Guntin & Gust has earned a #1 Ranking
for Allowance Rate in Tech Center 2600 while also achieving a Top 10
ranking overall for this Tech Center.




G&G provides IP services in the following USPTO Tech Centers:

Technology Center 2600 – provides examination for patent applications relating to Communications

Technology Center 2400 – provides examination for patent applications including Computer Networks, Multiplex, Cable and Cryptography/Security

Below are snapshots of Juristat’s 2022 rankings in these 2 Tech Centers.


Juristat ranks national IP firms annually and requires that firms meet a volume threshold (minimum of 100 applications disposed in a tech center within the 12 months being reviewed) to be included in the report. They then evaluate each IP firm’s performance based on three key metrics:

    • Number of applications filed
    • Allowance rate
    • Average number of office actions before allowance

Five years ago, Atanu Das, Partner at Guntin &Gust, founded the Diversity, Equity and Inclusion Committee at Intellectual Property Law Association of Chicago (IPLAC). Mr. Das identified an opportunity for a committee to increase awareness of DE&I issues among IPLAC members and correspondingly to aid in promoting changes within the expanded IP community. He subsequently served as co-chair of the committee for several years. Mr. Das has spearheaded a significant push in DE&I programming in an effort to accelerate learning and initiate change.

Mr. Das developed a DE&I program of events that included topical internal book club and film discussions enabling further education, open communication and sharing of personal experiences. CLE programming and special developmental seminars were also created for patent agents, attorneys and IP professionals throughout the Chicago area, focusing on the issues involved in providing equity in the workplace.

Additional targeted programming has been conducted through student outreach. As a Distinguished Scholar in Residence for Loyola University School of Law, Mr. Das’ experience provides the insight to work with under-represented student groups, such as the Society of Women Engineers. Early educational programming that introduces these students to the connections between STEM and law is a key factor in promoting future careers in IP law.

In recognition of their hard work and multichannel programming efforts, IPLAC announced the DE&I Committee as the winner of the Committee Award for Most Impactful committee in 2021.


IPLAC’s DE&I Committee “promotes diversity, equity and inclusion within IPLAC itself and the Chicago IP Community at large through programming, outreach, opportunities for mentorship and sponsorship, assessing opportunities for improving diversity and formulating diversity equity, and inclusion strategies.”



Patent Bots’ automated patent proofreading tool is used to review all of the issued patents in the prior year.  Only firms and companies with a minimum of 50 issued patents for the year are included in the review.  The quality scores awarded to firms are based on the average number of errors found in issued patents.

For their 2022 Patent Quality Rankings, Patent Bots reviewed over 300,000 patents and ranked the 736 most active patent law firms.  Their review covers: average number of numbering, antecedent basis, and word support errors detected in patents.

Guntin & Gust earned top rankings in Tech Centers 2400 and 2600 and an overall ranking in the top 25.
