38 F.4th 331
3d Cir.2022Background
- Pyrotechnics Management (FireOne) develops a proprietary communication protocol (control panel ↔ field module) used to trigger fireworks; fireTEK reverse-engineered the hardware and built a compatible router.
- Pyrotechnics submitted a seven-page Deposit Copy describing the protocol to the Copyright Office and received a Certificate of Registration.
- Pyrotechnics sued fireTEK (and U.S. distributor XFX) for copyright infringement and obtained a district-court preliminary injunction barring sale/distribution of fireTEK’s router.
- The Deposit Copy describes a 12-byte digital message format (96 bits), identifies four message types, and explains FSK-based analog transmission; it does not include source or object code or verbatim full bit sequences.
- The Third Circuit held the transmission scheme is a non-copyrightable "method of operation," the 12-byte format is part of the uncopyrightable idea, and the specific messages lack the minimal originality required for copyright; it vacated the injunction and instructed dismissal of the copyright claim.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Are transmission scheme elements copyrightable? | Pyrotechnics treated its transmission details (FSK, frequencies, data rate) as part of the copyrighted protocol. | Those elements are methods of operation or processes excluded from copyright. | Held: Transmission scheme is a "method of operation" under §102(b) and uncopyrightable. |
| Is the 12-byte digital message format copyrightable (idea vs. expression)? | The format and its structure are protectable expression of an original work. | The format is the necessary means to achieve communication (the protocol's purpose) and thus an uncopyrightable idea. | Held: The format is integral to the protocol's idea and therefore uncopyrightable. |
| Are the individual digital "command" messages original and protected? | The specified messages (e.g., Enable Fire Power) are original selections and protectable. | Individual messages are mechanically produced by fixed rules of the format and show only de minimis creativity. | Held: Individual messages lack the minimal originality (creativity) required and are not protected. |
| Did Pyrotechnics show likelihood of success to support preliminary injunction? | Registration and asserted copyrightability justified the injunction. | No valid copyright exists, so Pyrotechnics cannot show likelihood of success. | Held: Pyrotechnics cannot likely prevail; injunction vacated and copyright claim dismissed with prejudice. |
