Patent Drafting and Prosecution

About

Transforming innovation into assets

A strategic plan is key to building a strong patent portfolio. If your patent is challenged, will it withstand those rigors and remain an asset, or will it become a liability?

At Finnegan, we train our professionals to draft and prosecute patent applications strategically, with the clients’ interests and instructions always at the forefront. Our attorneys also have experience with litigation and invalidation proceedings that enables them to provide the highest quality work by prosecuting applications with an eye toward enforcement as well as against challenges.

Our patent prosecution practice includes seasoned professionals as well as experienced junior team members with relatively low billing rates and often extensive technical and/or prosecution experience. The attorneys, patent agents, and technical specialists have science and/or engineering backgrounds, and many have earned advanced degrees in their technical fields and/or have industry experience. They strive to add value from the invention mining/invention disclosure stage by collaborating with the client’s scientific contributors to set boundaries and to define the scope of the developed invention. It is their intense focus to effectively communicate the achievements of our clients’ inventions during the patent prosecution process.

European, UK, and U.S coordination for global protection

Finnegan professionals annually file and prosecute approximately 3,500 patent applications at the European Patent Office (EPO), the UK Intellectual Property Office (UKIPO), and the U.S. Patent and Trademark Office (USPTO). They also file under the Patent Cooperation Treaty (PCT). The technologies at issue span nearly every industry sector, including semiconductors, medical devices, chemicals, metals, pharmaceuticals, biotechnology, industrial manufacturing, robotics, consumer electronics, computer software, and business methods.

Our European, UK, and U.S. patent professionals often work side by side to provide clients with strategic and cost-efficient coordination of their patent portfolio. They provide a well-coordinated, consistent, and comprehensive global prosecution strategy that maximizes patent protection and minimizes costs associated with foreign filing and prosecution.
