Who We Are

Brinks' President, Gus Siller provides a brief overview of the firm's 100-year history as strategic partners and colleagues to our clients.

Firm History

Over a Century of Service

Brinks Gilson & Lione is one of the largest intellectual property law firms in the U.S., and helps clients around the world protect and enforce their intellectual property rights. Our lawyers, patent agents and scientific advisors assist clients in all aspects of patent, trademark, unfair competition, trade secret, and copyright law. Brinks attorneys provide informed counsel with respect to innovations in a range of complex and valuable technologies, including pharmaceuticals, chemicals, bioengineering, industrial manufacturing, electronics and software and medical devices.

Diversity and Inclusion

Moving forward together

At Brinks, we know that diversity is the way forward—not just for our firm, but for a better and more inclusive legal and business community as a whole. Simply put, we are smarter, stronger and more creative when our ideas reflect different perspectives.

A firm commitment

We don’t just support diversity—we actively seek it out. Reporting directly to our firm president, our Diversity & Inclusion Committee leads an array of initiatives to help people of different races, genders and sexual orientations succeed at Brinks, including:

  • Firmwide cultural competence training

  • Robust mentoring programs

  • Recruitment at minority job fairs and law schools

  • Sponsorship of diverse legal and charitable organizations

  • Active involvement in minority networking organizations

  • Meaningful, high-profile work assignments for all professionals.

Diversity hiring above the national average

Diversity is not a competition—if all law firms excel at it, everyone wins. However, we are proud that our diversity & inclusion recruiting numbers are well above the national average—particularly unusual for an IP-focused firm where the need for scientific and technical backgrounds limits our hiring pool.

We're pleased that in 2017, our fall class was 62% minority and 87% female; our 2017 Summer associate class was 83% minority and women.

Building networks

Success as a lawyer is about more than getting the job and doing great work—it’s about forging relationships outside the firm that will help you advance in your career. We encourage (and financially support) Brinks lawyers who participate and assume leadership roles in minority networking organizations and professional development conferences, including:

  • Chicago Committee on Minorities in Large Law Firms (CCOM)
  • Minority Corporate Counsel Association (MCCA)
  • Coalition of Women's Initiatives in Law Firms
  • Institute for Inclusion in the Legal Profession (IILP)
  • National Asian Pacific American Bar Association (NAPABA)
  • Asian American Bar Association of the Greater Chicago Area (AABA Chicago)
  • Asian Pacific American Affairs Commission of Michigan
  • Indian-American Bar Association of Chicago (IABA)
  • Lambda Legal
  • Lesbian and Gay Bar Association of Chicago (LAGBAC)
  • Black Women Lawyers Association (BWLA)
  • Chicago Council of Black Law Student Associations (CCBLSA)
  • Korean Bar Associate of Chicago (KABA)
  • Minorities in the Profession Committee of the North Carolina Bar Association
  • Chicago Women in IP (ChiWIP)
  • Korean Bar Association of Chicago (KABA)
  • National Bar Association (NBA)

Creating Diversity

If you can't find diversity in the legal profession, make some! Brinks sponsors pipeline education programs in several underserved areas in regions where we have offices. The programs we support introduce elementary, middle, high school and beyond students to the possibilities of a legal career. And we make it possible for them to pursue their dreams by supporting scholarships including:

  • Legal Prep Charter Academy Sponsorships

  • ABA Judicial Internship Opportunity Program

  • Just the Beginning Foundation

Recognized for inclusiveness

We take great pride in the fact that that colleagues and clients have acknowledged our diversity efforts. The Minority Corporate Counsel Association (MCCA) has recognized the firm’s diversity and inclusion efforts and successes by naming BGL as a winner of the MCCA Thomas L. Sager Award for the Midwest Region, an achievement that continues to encourage us.

Portrait of a Pipeline—The Legal Prep Story

We feel a parent’s pride in West Chicago’s Legal Prep Charter Academy—probably because we’ve supported the school since before it had students, teachers or even a building. This unique high school provides a law-themed education for students from a community historically underrepresented in the professions. Every year, more than 20 Brinks lawyers mentor Legal Prep student interns, familiarizing them with the legal environment, working with them on cases and helping them toward successful, productive futures. In 2016, Legal Prep’s first class of graduating seniors boasted an impressive 100% admissions rate to four-year colleges and universities. We couldn’t be prouder!

Brinks' Docketing System

Custom Analytics

Our docketing system captures detailed USPTO data from the PAIR system, including art unit and examiner data. Our docketing system enables client specific analysis of your portfolio to help obtain a better understanding of how your applications are progressing through the USPTO and to identify potential roadblocks in advance.

Community Involvement | Pro Bono

Serving Our Communities

Brinks Gilson & Lione has a firm-wide commitment to pro bono work.  Recognizing that our attorneys have a professional responsibility to contribute time, skills, and other resources to provide necessary legal services to members of the public who could not otherwise afford them, we formally organized and approved a written pro bono policy in 2001 emphasizing that service to persons of limited means is the essence of pro bono. 

We believe our community is stronger and safer as a result of our attorneys participating in our pro bono program. For example, our attorneys have partnered with various legal-aid agencies to:

  • assist immigrant crime victims who have suffered mental or physical abuse and have helped law enforcement in the investigation or prosecution of criminal activity;
  • assist members of our community get back on their feet by assisting them with petitioning for executive clemency;
  • assist residents in housing court that are facing improper evictions;
  • act as court appointed guardians to represent the interests of minors; and
  • provide legal advice to artists and art organizations

Our pro bono program permits every attorney to represent need-based clients who qualify for our services.  In addition to the above-matters, attorneys at Brinks Gilson & Lione have assisted members of our communities by handling pro bono matters referred by:

  • Cabrini Green Legal Aid;
  • Chicago Volunteer Legal Services;
  • Federal Circuit Bar Association;
  • Indianapolis Bar Association;
  • Lawyers Committee for Better Housing;
  • Lawyers for the Creative Arts;
  • Legal Services of South Central Michigan; 
  • Utah Courts Office of Guardian ad Litem, and many others 

Brinks Gilson & Lione also serves our community in other ways.  For the past several years, the Firm has assisted the students of Legal Prep Charter Academy, a free legal-themed high school on the West Side of Chicago.  Legal Prep aims to provide a high quality education and increase the population of diverse attorneys in the legal profession.  Our attorneys have mentored high school juniors and seniors through mock-trial and negotiations programs, as well as through ACT tutoring.  Through this program, Brinks aims to prepare these students for the next stages of their education.


In addition to the time and skill provided by our volunteer attorneys, the firm makes annual financial contributions to organizations that provide additional legal services to persons of limited means, including:

  • Chicago Bar Foundation Investing in Justice Campaign
  • Coordinated Advice and Referral Program for Legal Services (CARPLS)
  • Legal Aid Society;
  • Public Interest Law Initiative (PILI), and many others

Through these contributions Brink Gilson & Lione strives to ensure that our local legal aid agencies can provide the necessary legal assistance to the members of our communities.

Cristo Rey Program

For more than 13 years, Brinks has sponsored four students as part of the Corporate Internship Program at Cristo Rey Jesuit High School. Each student works at the Firm one day each week in various departments to offset the cost of his or her education, and to experience a real-world work environment. The Firm pays a flat fee that is applied directly to a portion of the students' tuitions. The program was started in order to provide a quality education to students who could not otherwise afford it.

Brinks has been committed to the quality of the students’ hands-on experience. The skills developed in the program become the foundation of the skill sets they use later in their careers.  The Firm is pleased to include two Cristo Rey alumni among its full-time employee ranks.  


David Lindner was awarded the Award for Excellence In Pro Bono Service by the U.S. District Court for the Northern District of Illinois and the Federal Bar Association on May 1, 2019. David was presented with his award in a private ceremony hosted by Chief Judge Rubén Castillo. This award is a reflection of David’s hard work and dedication to pro bono service. David currently serves as chair of the firm’s Pro Bono Committee.
