Trademarks
What they protect: Brand names, logos, taglines, and distinctive marks that identify the source of goods or services.
Registration: Filed with the national trademark office (USPTO in the US, UKIPO in the UK, EUIPO for EU marks). Must search for conflicts first. USPTO fee: at least $350/class as of January 2025.
Duration: Indefinite, provided the mark is used in commerce and renewed (every 10 years in the US; every 10 years in the UK and EU).
Without registration: Common law rights only — harder to enforce; no nationwide presumption of ownership.
Patents
What they protect: Inventions, processes, and designs that are new, non-obvious, and useful.
Registration: Filed with the patent office (USPTO, EPO, UKIPO). Must be filed before public disclosure in most jurisdictions (US allows a 12-month grace period).
Duration: 20 years from filing date for utility patents; 15 years for design patents (US). Subject to maintenance fee payments.
Without registration: No patent protection — the invention is unprotected once disclosed.
Copyrights
What they protect: Original creative works — writing, software code, music, art, and other tangible expressions.
Registration: Copyright arises automatically on creation. Registration with the US Copyright Office provides enhanced remedies (statutory damages, attorneys’ fees) and is required before bringing an infringement suit in the US.
Duration: Life of the author plus 70 years (US and EU); 70 years from creation for works made for hire.
Without registration: Exists automatically but limited remedies in enforcement.
Trade Secrets
What they protect: Confidential business information — formulas, processes, customer lists, marketing strategies — that derive value from secrecy.
Registration: None — trade secrets are protected by maintaining actual secrecy through NDA agreements, access controls, and security measures.
Duration: Indefinite, provided secrecy is maintained.
Without protection measures: Once publicly disclosed, a trade secret loses protected status and cannot be recovered.
