For nearly 20 years, I-MAK has worked to erode the system that fuels medical innovation – using flawed data, misleading claims, and media influence to push policies that endanger future lives.
The Truth About I-MAK
“[I-MAK] does not transparently disclose or explain its underlying data, and the data differs by orders of magnitude from public sources like the US Orange Book and court filings.”
Thom Tillis
United States Senator
“When I-MAK’s patent numbers and market exclusivity periods were objectively assessed by the USPTO with the assistance of the FDA, the USPTO neither replicated nor confirmed any of I‑MAK’s patent numbers or exclusivity periods…”
Adam Mossoff
Chair, Forum for Intellectual Property, Hudson Institute
“Simply quantifying raw numbers of patents and exclusivities is an imprecise way to measure the intellectual property landscape of a drug product.”

The Truth About Patents

The Myth of
Patent Thickets

Product Hopping


The Myth of
Patent Evergreening
The Truth About Innovation
Medical breakthroughs save lives. Follow-on innovations make treatments safer, more effective, and more accessible. Patent protections make those breakthroughs possible.
“Follow-on biopharmaceutical innovations deliver substantial health and economic benefits by improving the safety and efficacy of existing therapies, addressing unmet patient needs, expanding therapeutic applications, and enhancing adherence.”

Congress Must Consider Accurate Data About Patent Thickets
“The most influential source of these patent thicket theories is the Initiative for Medicines, Access, and Knowledge, or I-MAK … but lawmakers shouldn’t take the group’s claims at face value.”

Patent Thickets, Evergreening and Product Hopping: Falsehoods vs. Fact
“The concept of evergreening is absolutely false. You cannot by law extend the life of a particular patent.”

Debunking Myths About Patents in the Pharmaceutical Industry
“A close examination of the arguments made by [I-MAK and others] reveals that they fundamentally misrepresent the vital role patents play in promoting drug innovation without inhibiting generic entry.”
Fact Check:
Misguided Attacks on Follow-On Patents Would Harm Patients
“Follow-on patents have no effect on the lifespan of other patents – meaning that generic and biosimilar competition can still enter the market when the original patent expires.”

Insights from the USPTO’s Drug Patent and Exclusivity Study
