Q: What if something was never published?
A: If it was created before 1978 and unpublished, it's protected for the life of the author + 70 years.
📜 Step-by-Step Guide
1. Identify the creation date
Start by figuring out when the work was created and/or published—this will dictate the copyright duration.
2. Use the “1923 rule”
If the work was published before 1923, it's in the public domain—no permission needed.
3. Use the 95-year rule
Published between 1923–1977? Copyright lasts 95 years. Time to do some light math.
4. Use the life + 70 years rule
For works created after 1978, the clock starts ticking when the author dies—and keeps ticking for 70 years.
5. Confirm publication status
Unpublished works follow different rules. Confirm whether the work was released to the public.
6. Double-check legal status
Use copyright lookup tools or check with a lawyer (hello, Miller IP Law!) to be absolutely sure.
📖 Historical Context
Copyright laws in the U.S. have changed dramatically over time. When Congress passed the first U.S. Copyright Act in 1790, it offered just 14 years of protection (renewable once). By 1909, lawmakers expanded it to 28 years, with a 28-year renewal—totaling 56 years of protection.
But things got complicated with the Copyright Act of 1976, which overhauled the system. This act standardized protections and extended durations, especially for newer works. It introduced the “life of the author + 50 years” rule, which was extended to 70 years under the Sonny Bono Copyright Term Extension Act in 1998.
This extension, sometimes dubbed the “Mickey Mouse Protection Act,” aimed to protect large corporate rights-holders like Disney. Now, modern works have longer protections than ever before. But this has led to debates around innovation and public access—after all, how long is too long?
🏢 Business Competition Examples
1. Disney and Public Domain
Disney’s original “Steamboat Willie” entered the public domain in 2024, sparking public excitement—and caution from Disney’s legal team.
2. Project Gutenberg
Project Gutenberg thrives by digitizing public domain books—mostly pre-1923 gems—and offering them free to the world.
3. Musicians Sampling Public Domain Tracks
Modern musicians often tap into public domain songs from the early 20th century to create royalty-free remixes.
4. Filmmakers Adapting Classic Novels
Film studios regularly adapt public domain books (like Frankenstein or Dracula) into new content without paying a cent in royalties.
💬 Discussion Section
Copyright law is a strange cocktail of logic, politics, and nostalgia. While it’s meant to protect creators, it’s also accused of overextending itself—delaying works from enriching the public domain.
Before 1923? You’re in the clear. After that, it’s time to do some arithmetic or lawyer-up. The 95-year rule has made many think twice before republishing old materials. And “life + 70” ensures a creator’s grandkids might benefit—but it also ties up cultural assets for decades.
Public domain isn’t just about access; it’s about creativity. Some of the most iconic modern works are based on public domain content. Think of Sherlock Holmes, King Arthur, or the dozens of A Christmas Carol spin-offs. The ability to reuse and remix old works fuels innovation—but only if the works are actually free to use.
And yet, the law’s complexity leaves many unsure. Can I read this old poem on my podcast? Can I resell a vintage movie poster? This is where IP firms like Miller IP Law step in—making the legal jargon digestible and helping you avoid an accidental copyright lawsuit over a 1920s jingle.
⚖️ The Debate
FOR longer copyright terms:
Supporters say it protects creators and incentivizes long-term artistic investment. If people know their work is safeguarded for life (plus their family gets 70 years of royalties), they’re more likely to create.
AGAINST longer copyright terms:
Critics argue that overly long terms hinder innovation, limit educational use, and delay access to cultural assets that could enrich society.
