Gilbert’s LLP

If you want a traditional solution to a common problem, traditional lawyers can help. If you want a creative solution to a complex problem, contact Gilbert’s LLP.

Gilbert’s is built to fit the legal and business needs of innovation-driven organisations. The firm’s practice encompasses litigation, patents, trademarks and branding, government relations and IP disputes across borders. Our lawyers, patent agents and staff work in a tightly integrated, multi-talented and principled manner to enable clients to overcome complex and unconventional challenges with creative solutions.

Gilbert’s sweet spot is intellectual property and advocacy. The firm focuses on key industries such as pharmaceuticals, software, technology, energy, clean tech, gaming and media and entertainment.

In April 2018, Innovation, Science and Economic Development Canada announced a Gilbert’s report on integrated approaches to managing intellectual property. The report included case studies of eight Canadian companies and recommends best practices for a successful IP strategy.


Gilbert’s is at home in the courtroom and the boardroom. The firm represents some of the largest pharmaceutical and tech companies in bet-the-company litigation. The firm is known for managing international legal disputes and litigating Canadian cases.

In the hotly contested pharmaceutical industry, the firm acts for both brand and generic manufacturers. In the emerging area of biosimilars, Gilbert’s is familiar with both sides of the industry.
