Deep Dive into Patent Law Aspects
What Are the Standard Patent Requirements?
| Requirement |
Explanation |
| Patentability |
Must be novel, non-obvious, and useful |
| Claim Definiteness |
Claims must be clear and supported by the specification |
| Adequate Disclosure |

Defenses to Patent Infringement
| Defense |
Explanation |
| Invalidity |
Challenge based on prior art, obviousness, or improper patent procurement |
| Non-infringement |
Product does not infringe the patent claims |
| Patent misuse |
Claims enforced outside patent scope |
| Equitable defenses |
Equitable considerations such as laches or unenforceability |
Key Takeaways
