# Legal Intellectual Property Filing

Intellectual property (IP) filing is the process of formally
registering legal protection for creative and inventive works —
patents, trademarks, and copyrights each protect a different kind of
intangible asset, with different filing processes and protection
scope.

## The main IP types

- **Patents** — protect inventions (a new process, machine, or
  composition of matter); see [[legal-patent-application]] for the
  filing process in more depth.
- **Trademarks** — protect brand identifiers (names, logos, slogans)
  used to distinguish goods/services in commerce; see
  [[legal-trademark-registration]] for the filing process in more
  depth.
- **Copyrights** — protect original creative works (writing, music,
  software code) automatically upon creation in many jurisdictions,
  though formal registration still provides significant additional
  legal benefits (like the ability to sue for statutory damages in some
  jurisdictions).
- **Trade secrets** — protect confidential business information through
  secrecy rather than public registration; unlike the other IP types,
  trade secret protection is lost once the information becomes public.

## Choosing the right protection

The right IP protection depends on what's actually being protected: an
invention needs a patent, a brand identifier needs a trademark, a
creative work is generally covered by copyright automatically (with
registration strengthening enforcement options), and information whose
value depends on staying confidential is better protected as a trade
secret than by any filing that would require public disclosure.

## Common pitfalls

- **Missing filing deadlines** — many jurisdictions have strict,
  sometimes very short, windows for filing (e.g. before public
  disclosure of an invention) after which protection may be lost
  entirely.
- **Filing for the wrong type of protection** — a trademark doesn't
  protect an invention, and a patent doesn't protect a brand name;
  matching the asset to the right protection type matters before
  filing, not after.
- **Public disclosure before filing** — publicly disclosing an
  invention or confidential information before filing can forfeit
  patent rights or destroy trade secret status in many jurisdictions.
- **Treating IP filing as a one-time event** — IP portfolios need
  ongoing maintenance (renewal fees, monitoring for infringement,
  monitoring for lapsed protection) well beyond the initial filing.
