David F. Crosby

David Crosby is a counsel in the Patents Group. He focuses his practice on intellectual property counseling and enforcement.

What do you focus on?

I work with clients to help them develop and implement intellectual property strategies that are tailored to their business needs.

Having worked as a software and systems engineer, an in-house corporate counsel and as an examiner in the U.S. Patent Office, has given me hands-on experience to help my clients develop and implement business processes for identifying and protecting their intellectual property. I also help my clients navigate their competitive landscape through freedom-to-operate counseling and assist with strategic acquisitions and due diligence.

I enjoy working with early stage companies and helping entrepreneurs to protect their ideas.

My practice also involves advising companies that receive government funding for technology development and helping them to understand and comply with the Federal Acquisition Regulations (FARs).

Important areas of concentration for me include: medical devices and diagnostic systems, computer software, encryption, computer networking devices and telecommunications systems (wired and wireless), secure communications and image processing.

What do you see on the horizon?

We will continue to see periods of uncertainty regarding the patent-eligibility of business and medical diagnostic methods and companies will need to consider using a more diverse portfolio of intellectual property, technology and business tools to protect their business assets.
