Anthropic, IBM, Meta, Microsoft, and six other companies launched the Shared AI License Foundation on April 8, 2026, creating the first coordinated patent licensing pool for AI foundation models. The organization bundles more than 33,000 AI patent families under a single licensing umbrella, with Jamster Capital, led by IP veteran John Amster, running day-to-day operations, according to the foundation's launch announcement.
The move is a direct response to a litigation environment that has become untenable for companies building at the frontier. Patent trolls — entities that acquire patents without operating any underlying technology, then sue for licensing fees — accounted for nearly 70% of all AI-related lawsuits in a single year, according to patent intelligence firm CIPHER. Deep learning algorithms are the primary target: more than 70% of AI patent lawsuits involve them. More than 1,000 AI-related patent lawsuits have been filed globally in the past five years, with the United States accounting for 65% and China 20%, CIPHER's analysis found.
Google and Microsoft have together faced more than 50 patent lawsuits over AI technology since 2018, according to CIPHER. IBM alone holds over 9,000 AI patents, the most of any company, which explains its seat at the founding table alongside Anthropic, Meta, and Microsoft.
The foundation — SAIL, for short — pools member patents into a shared library. Instead of suing each other or spending millions defending against shell companies, member companies draw from the same arsenal. Jamster Capital, which has managed several large patent pools, handles royalty distribution and enforcement.
The founding board includes Genentech, a member of the Roche Group, alongside the four AI labs. Block, the payments company led by Jack Dorsey, and design software firm Figma joined as members. eBay and TD Bank Group serve as board observers.
Worldwide spending on AI is forecast to total $2.52 trillion in 2026, a 44% year-over-year increase, according to analyst firm Gartner. That scale of investment makes the patent problem proportionally larger. As the financial stakes of building AI systems have grown, so has the incentive for patent holders to seek a share.
The launch announcement frames SAIL as purely defensive — a shield against trolls, not a weapon against competitors. That framing deserves scrutiny. Member companies control the most valuable patent portfolios in the field; pooling them could raise barriers for smaller companies that cannot join. The announcement does not address how licensing terms will be set for non-members or what access startups can expect.
What is clear is that four companies that compete aggressively on models and products chose to coordinate on IP. Forming a patent pool requires agreeing on terms, dividing royalties, and accepting shared exposure. That they did it signals how expensive the alternative had become.
The Shared AI License Foundation is now accepting membership applications. What the licensing terms look like — and who gets left out — is the next story.
