Litigation forms the cornerstone of our practice. Our track record in high-stakes IP disputes has established BAHR as a leading firm for complex matters demanding strategic acumen and technical expertise. We are particularly recognised for our work with major multinational pharmaceutical companies and international clients in aquaculture and energy technologies. Our litigation portfolio encompasses patent validity challenges, infringement proceedings, trade secret, copyright, trademark and marketing control disputes, and regulatory matters.

We advise on IP transactions, technology transfers, and IP-driven M&A across all industries. We handle licensing frameworks, technology development agreements, strategic partnerships, and joint ventures that protect and maximise IP value. Our practice has particular strength in franchising, marketing, and advertising within the retail sector, where we help clients navigate consumer protection and competition law requirements whilst delivering strategic counsel on brand protection and enforcement.
