You can still call it the John Hancock Tower, but the company that paid $930 million for New England’s tallest building can’t.

Now that John Hancock’s last lease in the office building has expired, owner Boston Properties Inc. can no longer use the financial services company’s name on the property.

“We’re not allowed to call it that any longer,” Boston Properties president Doug Linde said Thursday during an earnings conference call with analysts.

Hancock, which built the 62-story Back Bay tower nearly 40 years ago, opened its new headquarters in the Seaport District in 2004, the same year it was acquired by Manulife Financial Corp. The final lease ran out earlier this year.

The new name Boston Properties has dreamed up for the sleek glass tower? It’s 200 Clarendon, a nod to its street address. Meanwhile, the low-rise portion of the Hancock has been rebranded as 120 St. James as part of a bid to lure tech tenants. []
