We are seeking a full-time, immediate, Attorney or Agent to join the patent prosecution team.

About Us!

We are a fast growing, thriving, mid-sized IP firm that originated in the mid 80s. We are proud to boast a family friendly culture, a casual dress code, and a very convenient commute to those living in the suburbs of Montgomery County. We prefer local candidates, as face time is part of the job, but technologically offer the ability to work from home when desired (we are in the office at the present time). Our ideal candidate has a few years of experience at a high volume firm, and is looking for a quality of life adjustment. At ESF, we celebrate diversity and we are committed to creating an inclusive environment for all employees.

We serve a diverse client base, which includes small start-up companies, academic institutions, and Fortune 500 companies having some of the world’s largest IP portfolios. This client base values our knowledge, experience, and commitment to their objectives. While we can certainly port in your book of business, this position is primarily to support the firm’s existing client workload capacity. Training will be provided to understand client expectations.
