Best Life Sciences Law Firm Ranking 2017

Life Sciences Law Firm Index | Q2 Update

The complex life cycle of a biotechnology product, pharmaceutical or medical device demands a broad range of legal expertise across many practice specialties. From intellectual property protection to corporate and regulatory advice, the leading law firms in the life sciences space combine sophisticated legal counsel with deep scientific knowledge.

Lake Whillans established the Life Sciences Law Firm Index to help identify which law firms are the most active and relevant for life science companies. The index was created in collaboration with our research partners at Breaking Media, the publishers of leading industry sites MedCity News and Above the Law.

We at Lake Whillans understand the vital role legal practitioners play in guiding a product through this enormously complex legal and regulatory landscape. The goal of the ranking is to inform innovators about firms leading the multi-faceted interplay between the legal market and the industry. Life sciences innovators rely on strong legal counsel to protect their interests at every stage of the product life cycle. However, in the case of an unforeseen and unavoidable setback, Lake Whillans is there to step in and help.

Our index was compiled using the criteria that matter most to healthcare innovators. In addition to collecting data in three practice categories — corporate, intellectual property and regulatory—we also incorporated information on the firms’ work with startup companies as well as their thought-leadership efforts to generate the index scores (a perfect score is 100).

Top Firms by Category



Cooley has had a truly remarkable recent run for life sciences transactions.  Cooley advised Medivation in its Decemeber 2016 acquisition by Pfizer for $14 billion. The deal will give Pfizer U.S. rights to Xtandi, a blockbuster treatment for advanced metastatic prostate cancer. In a deal announced in May 2016, Cooley also advised Jazz Pharmaceuticals on its $1.4 billion deal to acquire the clinical stage biopharmaceutical company, Celator Pharmaceuticals Inc. The firm was also busy with IPO work, including advising the underwriters in health IT genomics and analytics business NantHealth’s $91 million IPO (announced in June 2016) and advising Myovant Sciences in its $218 million IPO (October 2016). Myovant focuses on treatment for endocrine disorders.


Perkins Coie (updated 10/2017)

Through the first three quarters of 2017, Perkins Coie’s patent group has prosecuted more than 3,500 patent applications on behalf of life sciences and healthcare clients, and approximately 400 patents were issued to the firm’s industry clients. The firm’s patent litigators have also had a remarkable run of success in 2017. Among many other matters, Perkins Coie represented global pharmaceutical giant Mylan in its high-stakes and long-running patent battle against Teva Pharmaceuticals related to the drug Copaxone, a treatment for multiple sclerosis. In seeking FDA approval for a generic version of Teva’s Copaxone 40-mg product, Mylan challenged Teva’s patents as invalid. Teva sued Mylan under the Hatch Waxman Act in the U. S. District Court for the District of Delaware, alleging that Mylan’s generic Copaxone product would infringe four of Teva’s patents. Following a seven-day bench trial last Fall, the court ruled in January that all four patents were invalid.


Covington & Burling

Covington’s regulatory and government affairs practice has truly global reach. The firm is deeply involved in counseling trade associations in negotiating new European Union legislation concerning emerging technologies, including pharmacogenetics and gene therapy.  Covington also advises multinational biopharmaceutical companies on doing business in China, including setting and executing on the regulatory and legal strategies for engaging in drug R&D, manufacturing, and sales and marketing. In the United States, Covington is currently advising members of the pharmaceutical industry on FDA regulatory aspects of 21st Century Cures Act and the Senate’s Innovation for Healthier Americans initiative.

Startup work


WilmerHale has an enviable track record of success in counseling emerging life sciences companies. The firm serves as corporate counsel to Kala Pharmaceuticals—a clinical-stage pharmaceutical company focused on developing innovative ophthalmic products—including representing the company in a $68 million Series C preferred stock financing in 2016. WilmerHale also serves as corporate counsel providing financing, trademark, licensing and other advice to TransMedics, Ribon Therapeutics, BlinkBio, and Fulcrum Therapeutics, among others. In addition, the firm offers WilmerHale Launch, a resource for entrepreneurs and founders of startups in various stages of growth, providing tools and information on everything from formation to exit strategy.

A Note on Methodology

Our rankings methodology is designed to reflect a holistic view of the role of a law firm throughout the life cycle of a life sciences company: from inception through clinical trials.

In each category of practice, we identified the relevant, quantifiable factors. For example, under the Corporate category, our review included—but was not confined to—public and private financings, IPOs and M&A activity. For the Patent category, we included factors such as number of patents issued, “allowance rate” and successful patent defenses. Among the items in the Regulatory category are clinical trials, commercialization and approvals. The Thought Leadership ratings incorporated, among other things, the publication of white papers, contributions to third-party media, blogging and social media activity, as well as speaking or teaching engagements.

Within each category, firms were organized into tiers based on the complexity, value, variety and reach of their practice and scores were apportioned accordingly. Our rankings formula is as follows:

  • Corporate: 40%
  • Patent: 20%
  • Regulatory: 20%
  • Start-up work: 10%
  • Thought leadership: 10%

To complement our comprehensive review of all publicly available information, we invited firms to complete a questionnaire detailing their life science practices.
