Life Sciences Law Practice:

Few matters cut deeper into the pockets of both individuals and businesses than healthcare costs. Medical scheme fraud, reported to be widespread, has added substantially to these costs, as has the onslaught of HIV/Aids. Legislative change has also been dramatic in the healthcare industry, resulting in a rash of disputes over dispensing fees, medicine pricing and the advertising of health products.

In this context, the firm is at the cutting edge of legal developments in the health, pharmaceutical and life sciences sectors. For instance, the Werksmans Healthcare & Life Sciences team has helped to clamp down on fraudulent medical claims by representing medical schemes and administrators against erring healthcare service providers. We have also assisted employers in implementing workable, cost-effective HIV/Aids workplace programmes.

The diversified knowledge of the team is complemented by in-depth insight into South Africa’s evolving legislative and regulatory environment. This includes the black economic empowerment requirements of the Health Charter and the legal implications of the National Health Act, Consumer Protection Act and foodstuff laws as well as the proposed National Health Insurance Scheme. Other sought-after skills of the team include know how in product liability matters, consumer protection, licensing, distribution agreements and compliance with clinical trials regulations.

Expertise in these fields is sharpened by extensive international involvement, which includes representation at the World Association of Medical Law and the World Congress on Public Healthcare Law & Ethics. Team members are often speakers at local and global conferences, covering topics ranging from stem cell research and euthanasia to traditional African medicine.

The Healthcare & Life Sciences practice works closely with other practice areas within the firm in order to provide a holistic service to clients. Practice areas with which the Healthcare & Life Sciences practice works include but are not limited to the following: Environmental, Dispute Resolution, Mining & Resources and Competition.

Firm Overview:

As the legal matters confronting our life science clients are varied, so are the skill sets we employ. DLA Piper’s life sciences team comprises lawyers with legal, scientific and medical knowledge who understand the complexity of the business and regulatory environments in which our clients operate.

The challenges facing today’s biotechnology and medical device companies are greater than ever. For companies to take promising therapies from the laboratory to the market, they must protect those therapies from IP, regulatory and reputational risks. Furthermore, the last few years have seen increasing pressure from many sides: demand for greater shareholder return, loss of key revenue streams due to patent expiration or generic challenges, fierce competition in key therapeutic areas, pricing pressures from health care payors, increased government regulation beyond core safety issues, rising costs of R&D, challenges in maximizing return in emerging markets and aggressive government enforcement action.

Our life sciences sector team is one of the largest and most active of any law firm. Operating as one team across more than 30 jurisdictions, we combine subject matter experience with considerable knowledge of the sector, including the scientific, medical, regulatory, commercial and enforcement environments facing our biopharmaceutical, medical device, research and diagnostics clients.
