Invalidity and Non- infringement.

"Invalidity" and "non-infringement" are two important concepts in patent law, often considered in the context of patent disputes or litigation.

1:Invalidity refers to the legal determination that a patent is not valid, meaning that it should not have been granted in the first place. A patent can be invalidated for various reasons, such as:

- Lack of Novelty: The invention was not new or was publicly disclosed before the patent filing.-

-Lack of Inventive Step (Obviousness): The invention would have been obvious to a person skilled in the relevant field.

-Lack of Industrial Applicability: The invention does not have a practical and useful application.

-Insufficient Description (Lack of Enablement): The patent specification does not enable a person skilled in the art to carry out the invention.-

-Violation of Patent Requirements: The patent application did not meet certain formal or procedural requirements.

If a court or a relevant authority determines that a patent is invalid, it means that the patent holder's exclusive rights are no longer enforceable, and the patent may be revoked.

2.Non-Infringement:Non-infringement refers to the situation where a product, process, or service does not infringe on the valid claims of a patent. In other words, the accused product or process falls outside the scope of protection defined by the patent's claims.

To establish non-infringement, the accused party typically shows that their product or process does not include each element or limitation of the patented claims or that it employs a substantially different technology or approach.

If a court finds that the accused product or process does not infringe on the valid claims of the patent, the patent holder cannot assert infringement claims against that particular product or process.

Both concepts play a crucial role in patent litigation and disputes, and the determination of either invalidity or non-infringement can significantly impact the outcome of a case. It is essential to consult with legal experts, such as patent attorneys, when dealing with patent-related matters to fully understand and protect your rights.
