Navigating Section 102 of the Patent Act: Protecting Your Innovations
Understanding the nuances of Section 102 of the Patent Act is crucial for inventors and businesses looking to secure patent protection. This section, which governs what constitutes prior art, can be the difference between a successful patent application and one that is rejected. Whether you’re dealing with public use, printed publications, or foreign disclosures, the complexities of Section 102 require careful attention to detail and thorough legal knowledge. This is officially cited as 35 U.SC. § 102 and its title of this section of the statute is “Conditions for patentability; novelty”.
At Verna Law, P.C. our team of experienced attorneys and patent agent is dedicated to helping you navigate the intricacies of patent law. In this post, we’ll explore the key provisions of Section 102, discuss how the America Invents Act (AIA) has reshaped the landscape, and provide practical advice for securing and defending your patent rights.

Understanding Prior Art and Public Disclosure
Prior art plays a pivotal role in determining whether an invention is patentable under Section 102. In essence, prior art refers to any evidence that your invention was known before the effective filing date of your patent application. This includes any public use, printed publications, or public disclosures of the invention. The United States Patent and Trademark Office has attorneys that review your patent application, so the patent examiner will compare your application to the prior art.
The legal definition of prior art under Section 102 has been shaped significantly by case law, especially in the context of what constitutes public use and the criteria for what qualifies as a printed publication. For example, if your invention has been used in public or disclosed in a printed publication, such as a research paper or a trade magazine, it could potentially bar you from obtaining a patent unless you can demonstrate that these disclosures fall within specific exceptions, such as those established by the America Invents Act (AIA).
Key Provisions of Section 102
Subject Matter
Section 102 specifies what qualifies as patentable subject matter, setting the stage for what can and cannot be patented. This section is foundational, as it determines whether an invention falls within the categories of patentable inventions under U.S. law.
Public Use
Public use refers to any use of the invention that occurs in public before the effective filing date. This could involve demonstrating the invention at a trade show, selling it in the marketplace, or even using it in a way that the public could observe. If the invention has been publicly used before the filing date, it could be considered prior art, which might bar the issuance of a patent.
Under the AIA, whether a reference is prior art is determined based on “the effective filing date of the claimed invention,” rather than the date of the invention. 35 U.S.C. § 102(a). Thus, a prior art reference includes other patent applications effectively filed, or other patents issued, before the effective filing date of the patent at issue. Id. § 102(a)(2). Section 102(a)(1) also defines prior art to include situations in which the claimed invention was “described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.”
Printed Publication
A printed publication under Section 102 is any document that has been made publicly available, which could include journals, online articles, or even a blog post. The date of publication is critical because if a printed publication predates your filing, it could be considered prior art against your application.
Foreign Country and Patentability
Section 102 also takes into account prior art from foreign countries. If your invention or a similar invention has been disclosed in a foreign country before the effective filing date of your U.S. patent application, it can affect your patent’s validity. International agreements, such as the Paris Convention, also play a role in determining how foreign disclosures impact U.S. patent rights.
Anticipation refers to a situation where a single prior art reference discloses all the elements of a claimed invention, rendering the claim not novel. Novelty is a fundamental requirement for patentability, meaning that an invention must be new and not previously known or used by others before the date of the patent application.
Anticipation in Terms of Patent Novelty
- Single Reference Requirement:
- For a claim to be anticipated, all the elements of the claimed invention must be found in a single prior art reference. This reference could be a prior patent, a published article, or any other public disclosure that predates the filing date of the patent application.
- Exactness:
- The prior art must disclose each and every element of the claimed invention as it is arranged or combined in the claim. This means that the prior art must be sufficiently detailed to describe the invention completely, without requiring any modifications or additional information.
- Effect on Patentability:
- If a claim is anticipated, it lacks novelty, and the patent for that claim cannot be granted. Anticipation is a complete defense in a patent validity challenge, meaning that if a claim is found to be anticipated, it is automatically invalidated.
- Legal Standard:
- The courts will compare the claimed invention to the prior art reference to determine if anticipation exists. The prior art must provide an “enabling disclosure,” meaning it must be sufficient to enable someone skilled in the art to make and use the invention.
Example of Anticipation:
Suppose an inventor files a patent application for a new type of chair with a unique combination of features: a specific type of adjustable backrest, a specific material for the seat, and foldable legs. If a single prior art reference (e.g., a previously published article or an earlier patent) describes a chair with the exact same adjustable backrest, seat material, and foldable legs, then the invention is anticipated by that reference. As a result, the claim for the chair would be considered not novel, and the patent could be rejected or invalidated.
Key Takeaway:
Anticipation under Section 102 of the Patent Act is about determining whether a claimed invention is truly novel by comparing it to existing knowledge in a single prior art reference. If that reference discloses all aspects of the invention as claimed, the invention is not new, and the patent claim fails the novelty requirement.
The Role of Filing Dates and Inventor’s Certificates
The effective filing date of the claimed invention is a critical factor in patent law. It determines what constitutes prior art and whether your invention can be patented.
Provisional and PCT Applications
A provisional application can secure an early filing date, which can be beneficial in determining what qualifies as prior art. Similarly, a Patent Cooperation Treaty (PCT) application allows inventors to seek patent protection internationally while maintaining the benefit of an earlier filing date in the U.S.
Grace Period and Statutory Bars
The one-year grace period under Section 102 allows inventors to file a patent application within one year of certain public disclosures, such as public use or printed publications. However, if you miss this window, your own disclosures could act as prior art against your patent application, creating a statutory bar to obtaining a patent. Protection of industrial property is important for your business’ value and understanding that filing before the grace period ends is paramount.
The Impact of the America Invents Act (AIA)
The America Invents Act (AIA) brought significant changes to Section 102, most notably the shift from a “first to invent” system to a “first inventor to file” system. This change has altered the landscape of patent law in the United States, making the filing date even more critical in determining patent rights.
Pre-AIA Law vs. Post-AIA Law
Pre-AIA 35 U.S.C. Section 102, the United States operated under a “first to invent” system, where the date of conception could play a role in determining priority. However, the AIA changed U.S Patent Law and introduced the “first inventor to file” rule, which means that the first person to file a patent application generally has priority over other inventors, regardless of who conceived the invention first. The respective dates of conception between two parties now no longer matters. The date of the application to the patent office matters. Earlier filing dates of patent applications matter.
“In 2011, Congress enacted the Leahy-Smith America Invents Act (AIA), transforming the U.S. patent system from a first-to-invent to a first-inventor-to-file system for determining patent priority.” SNIPR Techs. Ltd. v. Rockefeller Univ., 72 F.4th 1372, 1373 (Fed. Cir. 2023) (citing Pub. L. No. 112–29, 125 Stat. 284 (2011)). In doing so, Congress “redefined what constitutes ‘prior art’ against a patent or application” by amending section 102 of the Patent Act. Id. at 1375. Section 102(a)–(b) as revised by the AIA is quoted in Appendix A to this opinion.
Prior Art Exceptions
The AIA also introduced new exceptions to prior art, which can be crucial for inventors who have disclosed their invention before filing a patent application. These exceptions provide some protection against your own disclosures being used as prior art against you. A prior art exception is very narrow.
- Pure pre-AIA patents and applications: patents and applications that have only ever contained claims with pre-AIA effective filing dates (i.e., before March 16, 2013) are subject to the patentability requirements and Interference Provisions in the pre-AIA versions of 35 U.S.C. §§ 102, 103, 135, and 291. AIA § 3(n)(1).
- Pure AIA patents and applications: patents and applications that have only ever contained claims with post-AIA effective filing dates (i.e., on or after March 16, 2013) are subject to the patentability requirements and derivation proceedings in the AIA versions of 35 U.S.C. §§ 102, 103, 135, and 291. AIA § 3(n)(1).
- Mixed patents and applications: patents and applications that contain (or contained at any time) at least one claim with a pre-AIA effective filing date and at least one claim with a post-AIA effective filing date are subject to the patentability requirements in the AIA versions of 35 U.S.C. §§ 102–103 but are also subject to the pre-AIA Interference Provisions. See AIA § 3(n)(1)–(2).
Section 102 in Practice: Key Court Decisions
Over the years, Supreme Court and Federal Circuit decisions have shaped how Section 102 is interpreted and applied. For instance, cases like Milburn v. Davis-Bournonville have clarified the rules regarding prior art, while more recent decisions have addressed the complexities introduced by the AIA.
District Court Examples
District courts across the country have applied Section 102 in various contexts, often dealing with disputes over what constitutes prior art and the impact of filing dates. These cases highlight the importance of thorough legal representation in navigating the challenges of patent law.
Federal Circuit Examples
Case Summary: Sanho Corp. v. Kaijet Technology International Limited, Inc.
Court: United States Court of Appeals for the Federal Circuit
Date: July 31, 2024
Citation: 108 F.4th 1376
Background:Sanho Corp. sued Kaijet Technology International Limited, Inc. (“Kaijet”) for patent infringement, asserting claims related to a particular type of multiport adapter for electronic devices. Kaijet challenged the validity of Sanho’s patent, arguing that the patent was invalid under Section 102 of the Patent Act due to prior art. Section 102 deals with the conditions for patentability, particularly concerning novelty and prior art.
Section 102 Issues:The primary issue in this case revolved around whether the patent claims were anticipated by prior art, making the invention unpatentable under 35 U.S.C. § 102. Kaijet presented several prior art references, arguing that they disclosed each element of the patented invention, thus anticipating Sanho’s claims.
Court’s Analysis:The Federal Circuit analyzed whether the prior art references indeed disclosed all elements of the claimed invention as arranged in the patent. The court emphasized that for a claim to be anticipated under Section 102, a single prior art reference must disclose every element of the claim, either explicitly or inherently.
- Anticipation Standard: The court reiterated the standard for anticipation, noting that a patent claim is anticipated if a single prior art reference describes each and every element of the claim, either explicitly or inherently, as it is arranged in the patent. The court carefully examined the prior art references cited by Kaijet to determine if they met this standard.
- Prior Art Analysis: The court conducted a detailed comparison of the patent claims with the prior art references. It considered whether the references disclosed the claimed combination of elements in a way that would be understood by someone skilled in the art at the time of the invention. The court found that while the prior art did contain many elements of the claimed invention, it did not disclose the specific arrangement of those elements in the same way as the Sanho patent.
Conclusion:
The US Court of Appeals for the Federal Circuit upheld a decision by the Patent Trial & Appeal Board (PTAB) in Sanho Corp. v. Kaijet Technology Int’l Ltd., Inc., Case No. 23-1336 (Fed. Cir. July 31, 2024), confirming that a private sale of a product embodying the claimed invention does not qualify as a “public disclosure” under 35 U.S.C. § 102(b)(2)(B).
Sanho, the owner of a patent for a port extension apparatus designed to enhance connectivity between devices, faced an inter partes review (IPR) initiated by Kaijet, which challenged the validity of certain claims on the basis of prior art. The PTAB found that the claims were invalid due to an earlier effective filing date of the prior art reference. In response, Sanho contended that a prior sale of its HyperDrive device by the inventor should disqualify the prior art, asserting that this sale constituted a public disclosure under the America Invents Act (AIA).
The PTAB, however, ruled that Sanho did not demonstrate that the HyperDrive sale was publicly disclosed before the prior art reference’s filing date, and Sanho’s patent was invalidated. Sanho subsequently appealed.
On appeal, the Federal Circuit focused on the interpretation of “public disclosure” under § 102(b)(2)(B). Sanho argued that the phrase “publicly disclosed” should be understood to include private sales without confidentiality obligations. The court rejected this argument, clarifying that “publicly disclosed” implies a narrower meaning than just “disclosed.” According to the court, the statutory language of the AIA requires that the invention must be made accessible to the public for the sale to qualify as a public disclosure. The court emphasized that the purpose of this provision is to protect inventors who make their inventions publicly available before the effective filing date of prior art by another party.
The Federal Circuit also referred to legislative history to support its interpretation, explaining that Congress intended the term “publicly disclosed” to mean public availability, not just any disclosure. Therefore, private sales—even without confidentiality—do not satisfy the requirement of public disclosure under the statute.
In affirming the PTAB’s decision, the Federal Circuit concluded that Sanho’s prior sale did not prevent the prior art from being used to invalidate the patent, as the sale was not a public disclosure within the meaning of the AIA.
Practice Note: For inventors to benefit from the public disclosure exception under the AIA, any disclosure—whether a sale or other form of communication—must make the invention publicly accessible, not merely involve a private transaction.
Case Summary: Weber, Inc. v. Provisur Technologies, Inc.
Court: United States Court of Appeals for the Federal Circuit
Date: February 8, 2024
Citation: 92 F.4th 1059
Background:This case involves a patent dispute between Weber, Inc. (“Weber”) and Provisur Technologies, Inc. (“Provisur”) regarding a series of patents related to food processing technology. The core issue in this appeal was whether Weber’s patents were anticipated or rendered obvious under Section 102 of the Patent Act by prior art references.
Key Patents in Dispute:Weber owned several patents related to its food processing machinery, specifically machines designed to slice and process meat and other food products. Provisur challenged the validity of these patents, arguing that they were either anticipated or obvious in light of prior art, including prior patents and published articles in the food processing industry.
District Court Decision:The United States District Court ruled in favor of Provisur, finding that Weber’s patents were invalid. The district court concluded that the claimed inventions were anticipated by prior art under Section 102(a) and (b) of the Patent Act. Additionally, the court found the patents obvious under Section 103.
Appeal and Issues:Weber appealed the district court’s decision to the Federal Circuit, arguing that the district court erred in its anticipation and obviousness findings. The primary issues on appeal were:
- Whether the prior art references cited by Provisur indeed anticipated the claims of Weber’s patents under Section 102.
- Whether the district court correctly applied the legal standards for obviousness under Section 103.
Federal Circuit Decision:The Federal Circuit affirmed the district court’s ruling, agreeing that the patents were anticipated under Section 102. The appellate court found that the prior art cited by Provisur disclosed all elements of the challenged claims, thereby meeting the requirements for anticipation. The court also addressed the obviousness challenge under Section 103, holding that the combination of prior art references would have been obvious to a person of ordinary skill in the art at the time of the invention.
The court’s analysis focused on the proper interpretation of the claims in light of the prior art and emphasized the importance of considering the ordinary meaning of claim terms and the scope of the prior art in assessing anticipation and obviousness.
Conclusion:The Federal Circuit’s decision in Weber, Inc. v. Provisur Technologies, Inc. underscores the rigorous standards for patent validity under Sections 102 and 103 of the Patent Act. The court’s affirmation of the anticipation and obviousness findings highlights the critical role of prior art in challenging the validity of patents, particularly in highly technical fields like food processing technology.
Practical Considerations for Inventors and Patent Applicants
To maximize the chances of securing a patent under Section 102, inventors should focus on:
Diligence and Documentation
Maintaining thorough records of conception and invention dates is essential, especially in a “first inventor to file” system. Detailed documentation can also help establish reasonable diligence in reducing the invention to practice, which can be critical in priority disputes. The practice of the invention needs to be documented clearly, in case any prior art can be found in a year prior to the filing of the patent application or the creation of the invention. Any joint inventor that contributes to the practice of the invention can be an inventor on the filing of the application and the patent itself.
Obligations of Assignment
Understanding the obligations of assignment is vital for inventors, particularly when working with employers or other entities. Properly assigning patent rights ensures that the correct party holds ownership of the invention.
Interference and Priority Disputes
Although less common under the AIA, interference proceedings can still arise, particularly in the context of pre-AIA applications. These disputes determine who has priority when multiple inventors claim the same invention. A right of priority is rare in today’s world after the AIA because of the first-to-file system.
Conclusion
Section 102 of the Patent Act is a cornerstone of U.S. patent law, governing what constitutes prior art and determining the patentability of an invention. With the changes introduced by the America Invents Act, understanding the intricacies of Section 102 has never been more important.
