Seven deadly sins of the inventor
1. The invention is more complex
than the problem merits.
2. The invention is not kept secret
until the date of filing.
3. The invention isn't
new.
4. The inventor hasn't fully
considered the problem.
5. No-one wants it.
6. An invention is safer if it's
kept secret.
7. The inventor has an unrealistic
idea of the value of his invention.
