The advantages of e-filing of copyright applications include:
- Lower filing fee of $35 for a basic copyright claim (for online filings only)
- Fastest processing time of copyright registration applications
- Online status tracking of copyright registration applications
- Secure payment by credit or debit card, electronic check, or Copyright Office deposit account
- The ability to upload certain categories of deposits directly into eCO as electronic files
Even users who intend to submit a hard copy of the work being registered may file an application and payment online and print out an eCO-generated shipping slip to be attached to the hardcopy deposit.
At this time, the following types of copyright registration are not available in eCO: renewals, corrections, mask works, vessel hulls, groups of serial issues, groups of newspaper/newsletter issues, groups of database updates, and groups of contributions to periodicals.
