What it means
Copyright covers the expression of an idea, not the idea itself. Two people can write competing books about the same subject, but neither can copy the other's actual sentences.
This distinction is what makes copyright narrower than patents but far cheaper and easier to obtain, since no registration or examination is required in most countries. The rights bundle together several things: reproduction, distribution, public performance, display and the making of derivative works.
A business can license any of these separately, which is why the same piece of software or the same photograph can generate several distinct revenue streams. Ownership normally starts with the creator, but work produced by employees in the course of their job usually belongs to the employer.
In accounting terms, copyright only appears on the balance sheet if it was purchased. A copyright developed internally is generally expensed as it is created, so a media company's own catalogue may be worth a great deal while showing almost nothing in the accounts.
An acquired copyright, by contrast, is capitalised at cost and amortised over its useful economic life. Useful life for accounting is not the same as legal life.
Copyright may legally run for decades after the author's death, but the commercially useful period for a software product might be three years and for a textbook perhaps ten. Auditors expect the amortisation period to reflect the realistic earning life, not the statutory maximum.
The most common commercial problem is not infringement by strangers but unclear ownership internally. Work produced by contractors, agencies and freelancers does not automatically transfer to the paying business unless the contract says so.
Businesses discover this at exactly the wrong moment, typically during due diligence on a sale or funding round.
In practice
Real-world examples.
Example
A training company licenses its course materials to three overseas partners for an annual fee, relying on copyright to stop the partners reselling the content after the licence ends. When one partner continues distributing the workbooks, the copyright notice and dated version control give the company the evidence it needs.
Example
A games studio acquires the copyright to a dormant franchise for $2,400,000 and amortises it over eight years at $300,000 a year. The purchased rights sit on the balance sheet, while the studio's own new titles are expensed as development costs.
Example
A marketing agency discovers during an acquisition that the photographs on its flagship client campaign were commissioned without a written assignment. The photographer still owns the copyright, and the agency has to negotiate a retrospective licence before the deal can complete.
Think of it
“Copyright protection is the legal right to control your creative work-ownership of original content.
Formula
Calculation
Annual amortisation = (Cost of acquired copyright - Residual value) / Useful economic life in years
Carrying value = Cost - Accumulated amortisation
A publisher buys the copyright to a technical reference series for $600,000. It expects the series to generate revenue for 15 years and assigns no residual value.
Annual amortisation = ($600,000 - $0) / 15 years = $40,000 per year
After four years:
Accumulated amortisation = $40,000 x 4 = $160,000
Carrying value = $600,000 - $160,000 = $440,000
If the series earns royalties of $95,000 a year, the annual contribution after amortisation is $95,000 - $40,000 = $55,000. Should a competing title cut expected royalties in half from year five, the publisher would need to test the $440,000 carrying value for impairment and probably write part of it off, because the remaining expected earnings would no longer support the book value.Case study
Seen in the real world.
This is an illustrative, fictional example. Harrowgate Learning, an invented e-learning business, built its entire product from video modules produced over six years by a rotating group of freelance instructional designers. The founders assumed that paying invoices meant owning the output.
When a larger education group offered to buy the business, its lawyers asked for the chain of copyright assignments. Harrowgate had written assignments for eleven of thirty-four contributors. The remaining twenty-three had signed nothing beyond a purchase order, which under the relevant law left copyright with the individual creators.
In this fictional case, the sale completed four months late and at a reduced price, with $1,200,000 held in escrow against the risk that a former contributor would object. Harrowgate spent those four months tracking down freelancers and paying modest assignment fees, a problem that a one-page clause in the original engagement letter would have prevented entirely.
Watch out
Common mistakes.
- Assuming that paying a contractor for creative work automatically transfers copyright, when in most jurisdictions it does not without a written assignment.
- Amortising acquired copyright over its full legal life rather than its realistic commercial life, which understates the annual cost and overstates the asset.
- Expecting internally created copyright to show up as an asset in the accounts, when development costs are usually expensed as incurred.
Questions
People also ask.
Does copyright need to be registered?
Not in most countries, since protection arises automatically on creation, though registration can strengthen enforcement and evidence in some jurisdictions.
How long does copyright last?
It varies by country and work type, but for authored works it commonly runs for the life of the creator plus 70 years.
Can a business protect an idea with copyright?
No, copyright protects the specific expression, so protecting an underlying idea or method requires a patent, trade secret protection or a confidentiality agreement.
