Game Boy Emulator 'Delta' for iPhone Updates App Icon After Adobe 'Threatened Legal Action'

The developers behind the popular Game Boy emulator Delta for the iPhone said they updated the app's icon today to avoid potential legal action from Adobe.

"Adobe threatened legal action unless we changed our app icon — so we did," say the release notes for the latest version of Delta on the App Store.

Delta's former icon does look like a mirrored version of Adobe's logo, which is a registered trademark in the U.S. and other countries. According to the U.S. Patent and Trademark Office, companies have an obligation to enforce their trademarks, and failure to do so could eventually result in losing rights to the trademark.

"Without proper policing over time, the original owner of a mark could lose any trademark rights it has in the mark," the U.S. Patent and Trademark Office says.

Apple has enforced its trademarked logo in similar ways over the years, including in 2020, when it filed a complaint against a small company with a pear logo.

Thanks, Parker Ortolani!

Update: The Verge shared some more details about the situation, and says that Delta's current logo is only a temporary solution as it designs an all-new icon.

I don't think this often, but I can actually see where Adobe is coming from on this one.

So I see where Adobe is coming from too, but can you really copywrite a Δ symbol?

They could've just done a delta symbol without the gap in the bottom line. Then they can say "Adobe didn't invent the Greek alphabet"
