Not only was last year the most active one on record for corporate venture capitalists—who participated in close to 20% of all deals—but Google Ventures was the most influential of the bunch. Intel Capital (INTC) and Salesforce Ventures (CRM) were on its heels as No. 2 and No. 3, respectively, and the venture arms of Cisco (CSCO) and Samsung were also in the top 10 most active funds last year. (That’s by number of deals, not necessarily by money.)

Sure, the two-year-old Microsoft Ventures makes the top 20 ranking in CB Insights’ latest annual report, basically tying with GE Ventures. It’s getting far more active in this space, as evidenced by its recent hire of BlackBerry’s former head of developer relations. (Read: it’s getting far more serious about mobile investments.) Microsoft now has seven startup accelerator locations around the world. Its approach is different than many other corporate VC funds: it doesn’t take equity in the companies, instead it’s looking for “long-term value,” according to remarks made by its general manager last year.

Still, few of Microsoft’s 200-plus startups are household or boardroom names, and even Motorola Solutions (the company left after Lenovo’s acquisition of its mobile-phone sister business) is seeing bigger exits. Motorola had money in security startup Fixmo (acquired by Good Technology last June), wearables technology company Zephyr Technology (bought by Covidien), and biometrics innovator Lumidigm (snapped up by HID Global). None of those transaction values were disclosed.

I’ll bet Microsoft’s venture unit is more tweaked by the revelation that four out of the five biggest Internet tech deals last year involved either Google Capital or Google Ventures. That list includes additional financing for SurveyMonkey ($250 million total), Flatiron Health ($130 million), Slack Technologies ($120 million), and Cloudera ($160 million). Incidentally, you’ll probably remember that Intel was in on the biggest funding event: the $900 million Series F round for Cloudera.

By the way, IBM may generate more patents than any other U.S. company (a record 7,534 last year) but it doesn’t warrant a mention in the CB Insights report. Neither do Apple, Oracle, or SAP—at least not in the summary presentation.
