Biologics and Biosimilars

The Biologics Price Competition and Innovation Act of 2009 (BPCIA) provides a legal framework for FDA approval of biosimilar and bio-interchangeable follow-on biologic products, as well as a paradigm for related patent litigation.  
 
Our team of biotechnology attorneys routinely performs landscape searches and freedom to operate analyses with respect to target biologics for some of the world’s top developers of Biosimilars.  We understand both the value and potential threat represented not only by patents covering actual innovator biologics but also how to identify and handle the equally important patents related to biologic production, isolation, purification, storage, and administration.  
 
Seyfarth attorneys have been involved in patent prosecution and litigation related to a variety of biotechnologies and have deep technical expertise in:
  • Stem Cell Therapeutics and Screening Technologies
  • Immuno-oncology and immunotherapies related to prophylactic and therapeutic cancer vaccines, CAR-T’s and Checkpoint Blockades agonists
  • Antibody technologies including fully human and humanized antibodies, antibody fusion proteins,  phage display and bi-specific antibodies
  • Nucleic Acid based drugs such as siRNA, miRNA, mRNA 
  • Gene Therapies, e.g., AAV, Lentivrial and MVA vectors
  • Epigenetic and gene editing technologies such as CRISPR/Cas9
We also keep abreast of the rapidly evolving biosimilars legal landscape and frequently blog and speak at industry conferences on this topic and BPCIA strategies.   
 
Members of our team have been General Counsel of biotechnology companies.  As such, we understand the relevance of patent matters and weigh them in light of actual business strategies and if necessary address them through biosimilars patent litigation.

Complete Support Model 

We offer complete support relating to pharmaceutical and biological drugs matters.  For example, we also serve as appellate counsel to clients even when other law firms served as trial counsel. Recognizing that appeals in the Federal Courts usually terminate with the intermediate court of appeals, we work to ensure that a client’s victory is preserved on appeal or a negative verdict is overturned. Furthermore, we can assist clients in appeals to the U.S. Supreme Court either as counsel of record or as amicus counsel.  Our firm also has significant experience in handling International Trade Commission (ITC) actions.
 
Our practice also includes experience in Food and Drug Law involving pharmaceuticals and medical devices.  Seyfarth’s Food and Drug Group represents clients whose businesses are regulated by the Food and Drug Administration (FDA) and the Federal Trade Commission (FTC). Our clients include companies that manufacture and distribute pharmaceuticals, bulk chemicals, vaccines, biologics, medical devices, and cosmetics, as well as food and dietary supplements. Our attorneys assist clients throughout the developmental, approval, production, and marketing stages of products to ensure that clients understand existing rules and regulations and the need to develop new strategies to address the regulatory environment. Our attorneys provide valuable counsel to FDA-regulated companies because we understand the regulatory and policy components of FDA as well as the relationship between FDA and Congress, and we know how to litigate matters concerning both the FDA and FTC.
 
We further advise companies on the conduct of clinical studies on a national and international basis, on regulatory submissions and manufacturing as well as on FDA enforcement matters.  Our attorneys have experience involving the labeling, marketing, and development of both pharmaceuticals and medical devices.
 
Seyfarth Shaw LLP represents a diverse roster of clients, from multi-national corporations to cutting-edge start-up companies.  Whether we are acting as counselors or high-stakes litigators, Seyfarth is committed to obtaining our clients’ desired results promptly and efficiently.  We constantly examine the strategy at each phase of the case until resolution.  We also ensure that our cases and matters are staffed with the right team of lawyers and personnel, which offers clients both cost efficiency and a dedicated team backed by the strength and resources of one of the nation’s premier law firms.
