Key Consideration for Life Sciences Patent Litigation

Intellectual property litigation requires a different kind of advocacy: one that moves fluidly between legal doctrine and commercial reality, and that understands how a brand, a work, a trade secret, actually functions in the market.
Our trademark litigation practice covers infringement, passing off, depreciation of goodwill, and confusion-based disputes including matters turning on survey evidence and expert evidence of consumer perception. We appear regularly before the Trademarks Opposition Board, representing clients in opposition and cancellation proceedings that often determine a brand’s fate before a dispute ever reaches the courts.
Beyond trademarks, we act in copyright disputes, trade secret and confidential information matters. Our experience spans small businesses and emerging companies to Fortune 500 brands, across industries including pharma and life sciences, consumer goods, technology and financial services.
As with our patent litigation practice, we work both as lead counsel and as co-counsel or conflict referral counsel alongside a client’s existing legal team. We bring focused IP litigation experience to a file without disrupting the relationship the client already has with their usual lawyers.
