Understanding Patent Law – Novelty and Prior Art

In the intricate world of intellectual property, patent law novelty stands as a cornerstone of whether an invention is patentable. The concept of novelty, while seemingly straightforward, involves nuanced considerations that can make or break a patent application.

The Essence of Patent Law Novelty

In the U.S., patents are granted to inventors for contributing to the progress of society.  Patents are only granted for inventions which promote this progress through the development of something new.  Inventions which are not new don’t promote forward progress of society.

In patent law, novelty requires that an invention be new and not previously known. This requirement serves a fundamental purpose: to ensure that patents are granted only for genuine innovations that advance the state of the art. The novelty criterion prevents the patenting of already known or existing inventions, thereby maintaining the integrity of the patent system and encouraging true innovation.

Prior Art: The Nemesis of Novelty

Because patents are only awarded for inventions which are new, inventions which are not new, are not patentable.  In determining, whether something is patentable, patent examiners consider Prior Art.  Prior art is meant to cover all information that has been made available to the public before the filing date of a patent application. This can include:

• Published patents and patent applications
• Scientific articles and publications
• Public demonstrations or sales of the invention
• Online disclosures
• Any other form of public knowledge

Understanding the scope of prior art is crucial for inventors and patent attorneys alike, since it defines the landscape against which an invention’s novelty is judged.

Interesting Facts About Patent Law Novelty and Prior Art

1. The “Flash of Genius” Doctrine: Before 1952, U.S. courts used the “flash of genius” test to determine patentability. This subjective standard required inventions to result from a sudden spark of inventive genius rather than ordinary skill. The 1952 Patent Act replaced this with the more objective non-obviousness standard.
2. Grace Period Variations: While the U.S. offers a one-year grace period for inventors to file after public disclosure, many countries have no grace period at all. This can lead to unintentional loss of patent rights internationally.
3. Secret Prior Art: In some jurisdictions, including the U.S., unpublished patent applications can serve as prior art against later applications, even though they weren’t public at the time of filing.
4. The Phonograph Patent Controversy: Thomas Edison’s patent for the phonograph was initially rejected due to prior art from a French publication describing a similar device. Edison eventually secured the patent by demonstrating key differences.
5. The First Patent Troll: The term “patent troll” is often attributed to the 19th-century case of George Selden, who patented a “road engine” in 1895 but never produced it, instead collecting royalties from automobile manufacturers.

Public Disclosure vs. Statutory Bar: Understanding the Differences

in the U.S., a patent application may be filed on an invention up to one year after the invention is either publicly disclosed (“public disclosure bar”), or offered for sale (“on sale bar”).  While both public disclosure and statutory bar relate to patent law novelty, they operate differently:

Public Disclosure:

• Refers to any non-confidential revelation of the invention
• Can include academic seminars, trade shows, publications, experimental use, public demonstrations
• In the U.S., in certain circumstances public disclosure and a lack of filing within one-year of the date of the disclosure, can invalidate the novelty requirement.

Statutory On-
Sale Bar:

• A statutory On-Sale bar occurs when the invention becomes public as a result of a sale before filing.
• If an inventor publicly discloses their invention by offering it for sale they have a limited time frame to file a patent application.
• In the U.S. failure to file the application within the specified time period can result in the invention being ineligible for patent protection.
• In the U.S., the statutory bar for filing a patent is one-year from the On-Sale date

One way to prevent public disclosure can include use of a non-disclosure agreement (NDA).  Understanding the distinctions bewtween public disclosure vs. on-sale can be crucial to inventors.

The Importance of Novelty in Patent Registration and Enforcement

Patent law novelty plays a pivotal role in both the registration and enforcement of patents:

1. Patent Registration: There are several requirements that a patent application must meet in order to be eligible to receive patent protection. One of the most basic requirements is novelty, or newness.  To determine whether an invention is novel, patent examiners conduct prior art searches. Failing to meet the novelty requirement results in rejection of the patent application.
2. Patent Validity: Even after a patent is granted, it can be challenged on novelty grounds. If prior art is discovered that predates the patent and discloses the invention, the patent may be invalidated.
3. Enforcement Strength: Patents that clearly demonstrate novelty are typically stronger and easier to enforce against infringers. The more novel an invention, the broader the potential scope of patent protection.
4. Licensing Value: Highly novel patents often command greater licensing fees, as they represent more significant advancements in their respective fields.
5. Innovation Incentive: The novelty requirement encourages inventors to push the boundaries of existing technology, fostering genuine innovation.

Navigating the Complexities of Patent Law Novelty

For inventors and businesses seeking patent protection, understanding and navigating patent law novelty can be challenging. Here are some key strategies:

1. Conduct Thorough Prior Art Patent Searches: Before filing a patent application, a comprehensive prior art search can help assess the invention’s novelty and identify potential obstacles.
2. Maintain Confidentiality: Avoid public disclosures of the invention before filing, especially in jurisdictions without grace periods.
3. Document the Invention Process: Keep detailed records of the invention’s development, which can be crucial in establishing novelty and inventorship.
4. Stay Informed About Global Patent Laws: Different countries have varying rules regarding novelty and prior art. Understanding these differences is crucial for international patent strategies.

The Future of Patent Law Novelty

As technology advances and information becomes more readily accessible, the concept of patent law novelty continues to evolve. Some emerging trends include:

1. AI and Prior Art Searches: Artificial intelligence is increasingly being used to conduct more comprehensive and efficient prior art searches.
2. Blockchain for Invention Disclosure: Some innovators are using blockchain technology to create tamper-proof records of their inventions, potentially influencing how novelty is established.
3. Harmonization Efforts: There are ongoing international efforts to harmonize patent laws, which could impact how novelty is defined and assessed globally.
4. Challenges in Fast-Moving Fields: In rapidly evolving areas like software and biotechnology, defining and assessing novelty becomes increasingly complex.
