Apple has objected to or otherwise challenged at least 12 government requests to help extract data from locked iPhones since September, bolstering its argument that its current battle about a terrorist’s phone is not as unique as the Justice Department has maintained.

The other requests are listed in a newly unsealed court brief filed by Apple attorney Marc Zwillinger in response to an order from a magistrate judge in a Brooklyn federal court. That case involves a government request to search an Apple iPhone 5s for evidence about a suspect’s possession or sale of methamphetamine.

Apple has refused to extract data from the phone, even though it could (because the phone was running on an older operating system), arguing in court that it was “being forced to become an agent of law enforcement.”

Last week, a California magistrate judge ordered Apple to develop and install software to help the FBI break into an iPhone 5c belonging to San Bernardino killer Syed Rizwan Farook. Apple CEO Tim Cook refused to comply, issuing a public letter that set off a major new debate about digital privacy.

Several of the newly disclosed government requests to Apple are like the one at issue in the Brooklyn case — calling on the company to use its existing capabilities to extract data like contacts, photos and calls from locked iPhones running on operating systems iOS7 and older. But a few requests involve phones with more extensive encryption, which Apple cannot break. To comply in those cases, Apple would presumably be ordered to do something very much like what it’s being asked to do in the San Bernardino case: design new software to let the government circumvent the device’s security protocols and unlock the phone.

The Brooklyn magistrate judge, James Orenstein, appears sympathetic to Apple’s position. He asked Apple for more details “regarding other requests it has received during the pendency of this matter that are of a similar nature to the one at issue in the instant case.”

In his response, Zwillinger included a chart of nine different requests Apple has received under the All Writs Act while the Brooklyn case was ongoing. The act dates back to 1789, and directs companies to assist the government in order to carry out legal requests such as search warrants, as long as doing so doesn’t cause undue burden. That goes well beyond ordinary warrants for information that Apple can easily access.
