Gilbert's LLP

If you want a creative solution to a complex problem, contact Gilbert’s LLP.

Gilbert’s is a boutique law firm based in Toronto. Gilbert’s is built to fit the legal and business needs of innovation-driven organisations in creative industries, including pharmaceutical, software, technology, energy, clean-tech, gaming, and media and entertainment.

Launched in 2001 by managing partner Tim Gilbert armed with only a briefcase and a cellphone, Gilbert’s was founded on the aim to break out of the conventional approach to legal services. Our lawyers and staff work in an integrated, multi-talented and principled manner to enable clients to overcome complex and unconventional challenges with creative solutions.

With a practice that encompasses litigation, patents, trademarks, government relations and IP disputes across borders, our firm excels where law, science, business and government intersect.

Gilbert’s provides deep industry knowledge and excellent, responsive client service. Offering a robust and well-rounded team, the firm succeeds for clients because it strives to make business sense of the complex.

We also investigate, vet and incorporate the use of new software technologies, including secure communication tools, to streamline our intra-office work and create deliverables.

In April 2018, Innovation, Science and Economic Development Canada commissioned 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 has a reputation 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.


Gilbert’s has a robust rights creation team, including professionals with strong scientific and technical expertise. Our team-based approach allows our prosecution professionals to incorporate insights from litigation successes to improve client outcomes.


Gilbert’s acts for many major industry players, as well as individuals, in protecting valuable artistic and software assets. Vik Tenekjian leads the firm’s enforcement efforts.
