With a strong foundation of legal and technical expertise, our attorneys and patent agents manage highly sophisticated intellectual property for corporate clients at the forefront of global technological innovation.

Our attorneys and patent agents prepare and file patent applications with the U.S. Patent & Trademark Office, as well as achieve international patent protection through filings in foreign countries through our established network of affiliates. Over the years, we have prosecuted more than 10,000 patent applications, with over 3,300 applications currently pending. In addition, we have experience in ex parte and inter partes reexaminations, reissue applications, inter partes reviews (IPRs), and other post-grant proceedings.

We speak the same language as our clients – technologically and literally. Most of our patent attorneys and patent agents have earned graduate degrees in engineering, computer science or other disciplines, and have professional experience in the electrical and computer arts industries. We are adept in composing legal documents and preparing filings for even the most complex innovations in these fields. Many of our professionals are multi-lingual, conversant in German, Mandarin Chinese, Spanish, French, and other languages.


We offer a broad range of trademark services by leveraging our established network of affiliates, including counseling, registration, maintenance, protection, enforcement, litigation, licensing, acquisition, due diligence, and clearance projects. In addition to preparing and filing trademarks with the U.S. Patent & Trademark Office, we offer global brand protection and work with our established network of affiliates to achieve international protection when needed.

We represent plaintiffs and defendants in a wide variety of technologies. We have successfully litigated patent cases from filing through jury (and non-jury) trials in courts all across the country, including the International Trade Commission. In addition to our patent litigation experience, our lawyers have experience in trademark, trade dress, copyright, and unfair competition lawsuits. We offer a variety of billing scenarios designed to meet the unique needs of each client.

IP Counseling
We help clients manage, maintain, and enforce their patent portfolios. We specialize in portfolio management, whether for offensive, defense, or monetization purposes, and we align our advice to the client’s business strategy. Our litigation experience enables us to manage our clients’ patent portfolios from the perspective of what works and what does not work when it comes time to actually putting a client’s patent to use, whether it is an offensive, defensive, licensing, or other corporate use.

We also offer a wide variety of transactional IP services, including licensing, acquisitions, contracts and agreements, audits, infringement/validity/enforcement opinions, freedom to operate opinions, clearances, and due diligence projects.
