Nearly 85% of TD’s 2026 patents involve AI

AI accounted for close to 85% of TD Bank's patent filings in fiscal 2026, as the lender’s inventors pivoted sharply toward the technology. TD made roughly 450 AI-related patent filings during the year, up from about 300 in fiscal 2025, John Lee , TD’s head of patents, told FinAI News . It’s a steep acceleration for a bank that, as recently as 2024, said only about one in five of its filings touched AI. TD is Canada’s most prolific bank patent filer and ranks among the country’s top three filers overall, with more than 2,500 filings. Roughly 1% of its workforce — nearly 1,000 employees — are named inventors, Dan Bosman , senior vice president and chief information officer at TD Securities, said during the Open Source in Finance Forum in New York on Nov. 4. Much of the recent output from in-house builds such as TD AI Prism , a predictive foundation model assembled from dozens of smaller models, have generated more than 40 filings, he said. The patent surge coincides with a deepening open-source AI and technology push, Bosman said. Bosman recalled an era when banks insisted they were “too regulated, too complex, too controlled” to touch open-source code, an opinion he said is “long past.” The bank reports third-quarter earnings on Dec. 3.
