Tricorder had to be taken off of the App Store. It’s not like this was unexpected. Here’s what a DMCA takedown notice looks like.

Dear Mr. Baudais,

We received a written notice from CBS that CBS believes your application named
Tricorder infringes CBS’s rights. A copy of the notice is attached.

Accordingly, please take steps to review your application to ensure that it
does not violate the rights of another party. If this includes removing your
application from the App Store while you make changes, use the following steps:

Visit iTunes Connect at http://itunesconnect.apple.com

1) Select the “Manage Your Apps” area
2) Find the desired application in the list
3) Select “Remove From Sale”
4) Your application will no longer be available for sale on the App Store

Please remember that pursuant to your agreement with Apple, you are responsible
for any liability to Apple because of a claim that your application infringes
another party’s rights, and also that we may remove your application if we
believe that doing so is prudent or necessary. So that we don’t take unnecessary
steps, please let us know that this matter between you and CBS has been resolved
within three days of this letter.

Thank you for your immediate attention.

Sincerely,
**EDIT: NAME REMOVED**
