Patent Counseling and Prosecution

Strategic advice to protect and enhance patent portfolios

Clients in the life sciences, pharmaceutical, biotech and medical technology industries depend on Dechert’s experienced team for the full range of patent counselling needs. We are a stand-alone practice with top-tier clients who bring us their most important and complicated prosecution work.

We represent clients at all stages of their business lifecycle, from discovery through development, clinical testing and product launch. Recognizing the dual imperative of maximizing patent portfolio value and aggressively protecting patents worldwide, we strive to enhance our clients’ value and afford them the broadest protection.

Our strategic advice is informed by years of industry knowledge and experience as well as significant scientific and technical acumen. Many members of our practice hold a Ph.D. or other advanced degrees in the life sciences and have either postdoctoral or industrial research experience above and beyond their expertise as lawyers.

A track record for obtaining patent coverage beyond client expectations

Dechert’s patent counseling and prosecution team represents pre-public and discovery stage biotechnology pharmaceutical companies as well as established, publicly traded international pharmaceutical companies in worldwide patent portfolio development – from prosecution and counseling to due diligence, transactions, and infringement defense and avoidance. We routinely represent clients in patent disputes before the U.S. Patent and Trademark Office (USPTO). Our lawyers also have extensive experience and much success in developing strategies to protect second generation drugs and biologics.

Our patent counseling team has extensive “real-world” experience, drafting and prosecuting to issuance patent applications across the entire scope of pharmaceutical and biotech inventions. We also advise clients on the potential impact of new laws and proposed legislation on their IP portfolios and strategies.

Comprehensive services tailored to specific client needs

Our approach to patent counseling is to partner with our clients to achieve their strategic business goals. By combining high-level technical expertise and practical legal insight, we provide a full range of patent services, from proper documentation and disclosure of discoveries and inventions to patent procurement, licensing and enforcement.

We focus on building solid patent positions that deliver competitive advantage and value over time, whether the client is a pre-public discovery-stage company or a large publicly traded company.
