Difference Between Prior Art Search and Patentability Search | InventionIP

In the field of patents, two sorts of searches are important: prior art searches and patentability searches. Although these searches appear to be similar on the surface, they serve diverse objectives and are critical at various phases of the patent process. Understanding the distinctions between these searches is crucial for navigating the patent filing process and increasing your chances of approval.

While a prior art search identifies existing information or innovations that are comparable to yours, a patentability search dives deeper into assessing whether your idea fits the legal requirements for patent approval. This extensive guide explains the differences, the significance of each search, and how they all contribute to patent success.

What is a Prior Art Search?

A prior art search is the process by which an individual or patent professional searches previous innovations, patents, publications, and other sources of public knowledge to determine whether an invention has already been disclosed. It is an important stage in determining the novelty of an invention, which is one of the main requirements for getting a patent.

What is Considered Prior Art?

Prior art refers to any public disclosures that existed before the date of your patent application. It can take many different forms, including:

• Patents and applications have been published.
• Scientific and technical writings appear in periodicals or online.
• Products that are currently on the market.
• Public demonstrations or exhibits of comparable technology.

A prior art search might help determine whether or not an invention is actually unique. If prior art demonstrates that a similar innovation has previously been disclosed, your chances of securing a patent may be minimal. Conducting this search early in the patenting process can save you time and dollars by identifying potential roadblocks.

How is a Prior Art Search Conducted?

A comprehensive prior art search involves looking at multiple sources, including:

• Patent databases: Public and private databases such as the USPTO, WIPO, and EPO provide extensive records of existing patents and applications.
• Non-patent literature (NPL): Scientific papers, product manuals, technical journals, conference presentations, and other publications are essential sources.
• Internet searches: Online repositories and product listings can offer valuable insights into existing inventions and public disclosures.

The goal is to gather as much information as possible on technologies similar to yours to determine whether your invention is new.

What is a Patentability Search?

While a prior art search focuses on existing inventions, a patentability search digs deeper into whether your invention meets the legal requirements for patent protection. The key elements evaluated in a patentability search are:

• Novelty: Is your invention new, or has it been disclosed in the prior art?
• Non-obviousness: Even if your invention is new, is it sufficiently different and non-obvious when compared to existing technologies?
• Utility: Does your invention serve a practical purpose or provide a useful function?

A patentability search provides a more extensive assessment of whether your idea has a good possibility of being granted a patent based on the above legal criteria. While previous art searches focused on fact-finding, patentability searches go a step further by determining whether your idea meets the strict patent office standards.

How Does a Patentability Search Work?

A patentability search is typically carried out by a patent attorney or expert who examines both previous art and patent criteria. They evaluate your invention's chances of success by examining:

• Claims in existing patents: Analyzing the claims in similar patents can highlight whether your invention offers unique features.
• Non-patent literature: Publications relevant to your field may contain critical insights into whether your invention stands out.
• Patent laws and guidelines: Each country or region has its own patent laws, so a patentability search will consider the criteria specific to the jurisdiction where you plan to file your patent.

Ultimately, this search provides you with a clear idea of your chances of securing a patent and highlights potential areas for improvement in your invention.

Key Differences Between Prior Art Search and Patentability Search

While both prior art and patentability searches are important in the patenting process, they serve different functions & require different approaches. The following are the significant differences:

Objective

• Prior Art Search: The primary purpose of a prior art search is to find any existing inventions or disclosures that may preclude your invention from being considered novel. It examines if the audience is already familiar with the technology or concept.
• Patentability Search: A patentability search assesses if your innovation qualifies for a patent. It goes beyond detecting similar inventions to determine whether your idea is sufficiently unique and non-obvious.

Scope

• Prior Art Search: This search involves a broad review of existing patents, publications, products, and other forms of public disclosure. It looks for any evidence that the invention or similar technology is already in the public domain.
• Patentability Search: While it also reviews prior art, the patentability search focuses on how your invention compares to existing technologies in terms of novelty and non-obviousness. It is a more detailed analysis of the invention's patent eligibility.

Legal Focus

• Prior Art Search: The legal focus here is determining whether the invention is novel. The existence of any prior art that discloses the same or a similar invention could prevent you from obtaining a patent.
• Patentability Search: This search focuses on patentability requirements like novelty, non-obviousness, and utility. It evaluates whether your invention is not only new but also innovative and useful enough to warrant patent protection.

Timing in the Patent Process

• Prior Art Search: This search is often conducted early in the patenting process, before you file a patent application. It helps inventors determine if pursuing a patent is worth their effort.
• Patentability Search: Typically performed later, after an initial concept has been refined. It provides insight into whether your invention is likely to pass the examination phase at the patent office.

Legal and Technical Aspects

The legal and technical nuances of both searches also differ.

• Legal Aspects: Prior art searches deal with the novelty of an invention, ensuring it doesn't infringe on existing patents or public disclosures. Patentability searches, however, examine whether an invention meets specific legal criteria, such as novelty, non-obviousness, and utility, under patent law.
• Technical Aspects: Technically, a prior art search is broader in scope, as it scans a wide array of public disclosures. In contrast, a patentability search zooms in on the inventive aspects of an idea, focusing on whether the invention stands out from known technologies.

When Should You Perform Each Search?

The timing for conducting a prior art search and a patentability search is critical for the patenting process.

• Prior Art Search: This should be one of the first steps in the patenting process. Performing a prior art search early allows you to assess the novelty of your idea and understand the patent landscape. It helps in deciding whether to move forward with a patent application or revise the invention to avoid overlaps with existing technologies.
• Patentability Search: After confirming that your invention is new and unique through a prior art search, a patentability search should be conducted. This search ensures that the invention meets the legal requirements of patentability, including non-obviousness. Ideally, a patentability search should be done before you invest heavily in the patent filing process to avoid unnecessary expenses.

Why Both Searches Are Important for Patent Success

Both prior art and patentability searches are essential to the patenting process, serving different purposes but complementing each other in the overall strategy.

Prior Art Search: Understanding the Existing Landscape

A prior art search provides a crucial view of the current technological landscape. It helps inventors and companies understand whether their invention is truly novel or if a similar technology already exists. This knowledge can save time and resources by helping inventors refine their ideas early in the process.

Patentability Search: Ensuring the Best Chances for Approval

Once novelty is established, a patentability search ensures that the invention meets the legal standards required for patent protection. This search helps to avoid the disappointment of a rejected patent application by identifying any weaknesses in the invention’s eligibility. It also allows inventors to modify or improve their invention to meet the necessary requirements.

Maximizing Patent Success

When conducted together, these searches significantly improve the chances of obtaining a patent. A prior art search helps ensure that the invention is new, while a patentability search confirms that it is worthy of patent protection. Inventors who conduct both searches are better positioned to succeed in the patent process.

Skipping either search can lead to costly errors. If a prior art search is overlooked, the inventor may file a patent for an already known invention. On the other hand, neglecting a patentability search could result in rejection due to a lack of non-obviousness or other legal criteria.

Conclusion

Prior art and patentability searches are both important steps in the patenting process. They discuss several facets of patent approval, ranging from innovation to non-obviousness and beyond. By completing these searches, inventors may confidently navigate the complex patent landscape and improve their chances of acquiring significant intellectual property rights.
