We strive to make your success a reality by leveraging our firm’s top strengths:

Dedicated attorneys

At the beginning of each engagement, clients are paired with an experienced attorney who is deeply involved in all facets of the relationship, ensuring quality representation and a consistent strategy. Communication with our technically proficient legal team is effortless; we share our clients’ passion for their innovations and businesses.

Global connections

Our clients’ interests often extend beyond the US. Internationally, we’ve built a comprehensive network of partners and counsel in several key foreign jurisdictions that empower our clients to expand their reach globally.

Tech-forward client services

We utilize advanced software to enhance client experiences and minimize risk. Our state-of-the-art technology includes docketing systems, IDS creation, citation tracking, and annuities management, all supported by secure, cloud-based servers for data safety and recovery. This infrastructure, combined with our strict quality control measures, ensures that our clients always receive timely communications—and that critical deadlines are consistently met.

Extensive legal network

Our firm maintains relationships with respected legal providers whose services complement our own. This network includes specialists in intellectual property litigation, corporate law, and complex transactions. Such relationships allow our clients quick access to a broad range of expert legal solutions.

Foreign agent capabilities

We proudly serve as a foreign agent for many international law firms and global innovation leaders. Our firm is well-versed in prosecuting patents and trademarks for our foreign partners, and we ensure that every application is suited to the laws and best practices of the US.

A note to our international law firm partners: We look to establish mutually beneficial, reciprocal partnerships that enrich the experiences of our combined client bases.

Flexible billing model

Our firm utilizes a modern, flexible billing system that accommodates client-specific preferences. A firm partner reviews and approves all invoices before they are issued to clients. We intend each invoice to be clear and reasonable, with no surprises.
