The Biologics Price Competition and Innovation Act of 2009 (BPCIA), enacted in March 2010 as part of the Affordable Care Act, provides a pathway for FDA approval of biosimilar products in the United States, as demand by patients, insurers and government agencies for lower cost biopharmaceuticals has increased exponentially. Regulatory change combined with societal pressure for more affordable health care has greatly expanded the global market for biosimilars and will continue to do so. 

The global biosimilars market is expected to reach a yearly valuation of more than $69 billion by 2025. In order to capture valuable market share and achieve profitability, biosimilar product sponsors need legal counsel with experience in patent law, government regulation, and both biological and chemical sciences. Cozen O’Connor has a team of dedicated professionals with this experience and is a recognized leader in helping clients understand BPCIA regulations.

Typical pharmaceuticals, often-referred to as a “small molecule drugs,” have simple structures and are made by combining specific ingredients through ordered chemical processes under defined reaction conditions. Biologics, in contrast, are very large, complex molecules or mixtures of molecules that are manufactured by living systems such as microorganisms, plant cells, and animal cells. Small molecule drugs have well-defined chemical structures that can be precisely copied and confirmed through various analytical techniques. This means that the safety and efficacy of a generic small molecule drug can be confirmed without the need for clinical trials. Biologics are difficult, if not impossible, to definitively characterize, and establishing the safety and efficacy of a biosimilar product is a far more complex and costly endeavor.

The inherent differences between small molecule drugs and biologics create unique legal challenges. Attorneys at Cozen O’Connor can provide sophisticated advice on the full range of critical issues such as winning FDA approval, bringing a new biosimilar to market, responding to branded efforts to maintain exclusivity after patent expiration, and negotiating the thicket of validity and infringement issues posed by branded companies’ patent portfolios.

The question of what studies the FDA will require in order to approve a biosimilar product can mean the difference between success and failure. In order to win FDA approval, small molecule drugs must be shown to be chemically identical and biologically equivalent to the branded drug. This is generally shown through relatively simple in vitro and in vivo studies without the need for clinical trials. According to requirements in the BPCIA, biosimilar applicants must demonstrate a product’s biosimilarity or interchangeability using data derived from analytical studies, animal studies, and – importantly – one or more clinical studies, unless the FDA determines that certain studies are unnecessary. Cozen O’Connor can advise clients on how to design and promote a successful biosimilar application.

The law that regulates the introduction of generic drugs includes various sales and data exclusivities to balance the incentives for market entry for branded and generic companies alike. The BPCIA attempts a similar balancing act for biologic drug makers by establishing various exclusivities and other provisions that govern when and how new biosimilars can be marketed. Cozen O’Connor helps clients develop a smart strategy for market entry that satisfies statutory requirements and maximizes profitability.

Finally, because of the difficulty of characterizing biologics, branded companies often argue that the product is the process and try to maintain confidentiality regarding all aspects of the manufacturing process. As patent protection expires and biosimilar product applications are filed, branded companies are likely to try to protect their exclusivity by other means, such as citizen petitions and supply chain leverage. Cozen O’Connor attorneys are well prepared to respond to all such efforts and will protect clients’ lawful right to compete.


The members of Cozen O’Connor’s Biosimilars team have long been leaders in the intellectual property bar. They understand the legal, regulatory, economic and scientific issues that underlie and influence both the generic pharmaceutical and biosimilar industries. Our team includes attorneys with advanced scientific degrees in organic chemistry, molecular cell biology, and immunology, as well as former senior research scientists in industry and academia. Our team also includes seasoned patent litigators with over 20 years of experience, federal prosecutors, registered patent attorneys, a former patent examiner for the U.S. Patent and Trademark Office, and the former general counsel for the U.S. Office of Personnel Management. We at Cozen O’Connor understand how science and the law interact with respect to biosimilars, and we are able to help our clients navigate this complex and emerging field of law.
