Siino said he’s leaving to join the growing patent monetization industry, which includes businesses like patent brokerages.
He was hired in 2005 to build Yahoo’s IP department. Siino says he feels his work is done because the group, now with about 30 staff, could stand on its own.
Yahoo shed a number of executives this year and it started laying off 1,500 workers last week. Yahoo CEO Jerry Yang stepped down last month.
Siino declined to comment on the turmoil or layoffs at the company.
Siino’s group focused exclusively on intellectual property at Yahoo, building the patent portfolio, cutting licensing deals, and handling IP litigation.
When Siino arrived in 2005, Yahoo was filing about 100 patent applications a year. Now Yahoo is filing 1,000 patent applications a year, Siino said.
