Why Is a Novelty Search Important
Before Filing a Patent?
Bringing a new invention to market is a bold move. However, assuming your
idea is original without verifying it can result in wasted time, money, and
effort. This is where a novelty search becomes essential.
A novelty search, also known as a prior art search, helps determine whether
your invention is truly new. Patent offices like the USPTO will only grant
patents for inventions that are novel. If a similar idea already
exists—anywhere in the world, in any form of public disclosure—your patent
may be denied. This makes novelty searching one of the most critical steps
before drafting and filing a patent application.
Below, we explore the full scope of a novelty search, why it matters, when
to do it, how it’s done, and the pitfalls to avoid.
What Is a Novelty Search?
A novelty search is an in-depth review of existing inventions, technologies,
and literature to assess whether an invention has already been disclosed. It
focuses solely on the newness of an idea—whether the same or a
substantially similar concept already exists in public records.
The goal is to uncover “prior art,” which includes:
● Issued patents
● Published patent applications
● Scientific journals
● Technical documentation
● Online publications
● Public demonstrations or use
Unlike broader patentability or freedom-to-operate (FTO) searches, a
novelty search does not analyze commercial risks or legal ownership. Its
sole purpose is to check if someone has already thought of your idea and
disclosed it publicly.
Definition and Scope
A novelty search scans for documents that disclose any element of your
invention that could block a future patent. It must be global in scope, since
prior art can come from any country or language. Patent offices consider
disclosures from anywhere in the world when evaluating novelty.
This type of search is most effective when it focuses tightly on the
invention’s unique features—claims, functionality, configuration, or
mechanism—not general ideas or industries.
Difference from Patentability and FTO Searches
While related, these searches serve different purposes:
● Novelty search: Confirms if the invention is new.
● Patentability search: Includes novelty but also examines usefulness
and non-obviousness.
● Freedom-to-operate search: Checks if commercializing the invention
could infringe existing patents.
If you're at the idea or prototyping stage, a novelty search is the appropriate
first step.
Key Reasons to Conduct a Novelty Search
Skipping a novelty search can lead to denied patent applications, financial
losses, or missed competitive opportunities. Here’s why it should be
non-negotiable:
Avoiding Wasted Time and Money
Filing a patent can cost between $5,000 and $20,000 when including
attorney fees, government filing fees, and technical drawings. Without a
novelty search, you risk pouring these resources into an application that will
be rejected outright.
Example: An inventor once spent $8,000 filing a utility patent, only to
discover that a nearly identical invention had been published in a Korean
journal years earlier. A basic novelty search would have flagged this before
any money was spent.
Identifying Similar Inventions
Many inventions aren't 100% unique but rather improvements or
combinations of existing ideas. A novelty search shows what’s already out
there—helping you determine how to make your concept truly distinct.
You may discover:
● Existing patents with overlapping claims
● Products or prototypes solving similar problems
● Areas where innovation is still possible
Knowing the competitive landscape improves both your invention and its
protectability.
Improving Patent Draft Quality
Once you identify similar inventions, you can refine your own claims to
emphasize novelty. A well-informed patent application can better withstand
USPTO scrutiny and future litigation.
Attorneys can:
● Draft around existing prior art
● Use specific terminology to show differences
● Strengthen technical descriptions with supporting arguments
This leads to a more robust and enforceable patent.
Strategic Business Decisions
If the novelty search reveals that your invention is already patented or
widely disclosed, it may influence your decision to:
● Abandon or pivot the idea
● Enter licensing negotiations
● Focus R&D on alternative designs
This prevents late-stage surprises and aligns innovation with business
goals
When Should You Perform a Novelty Search?
Ideally, conduct a novelty search:
● Before preparing a provisional patent application
● Before disclosing the idea publicly
● Before approaching investors or partners
● Before spending heavily on R&D
Performing the search early allows you to adjust your design or pivot to
more promising ideas. Waiting until after a product launch or filing
increases the risk of legal and financial consequences.
Case Study: A startup pitched their prototype at a trade fair, only to be sued
months later by a company holding a patent on a similar mechanism. Had
they done a novelty search earlier, they would have discovered the existing
patent and avoided legal exposure.
How to Conduct a Novelty Search
There are two main approaches: do-it-yourself (DIY) and professional
searches.
Use of Patent Databases
DIY inventors can start with publicly accessible databases such as:
● Google Patents
● USPTO Patent Full-Text Database
● Espacenet (European Patent Office)
● WIPO PatentScope
Use a combination of:
● Keywords and technical terms
● Boolean operators (AND, OR, NOT)
● International patent classification codes
Search for synonyms, abbreviations, and variations of your invention’s
function. Review drawings, abstracts, and full-text documents.
However, DIY efforts have limitations. Language barriers, vague
disclosures, and hidden similarities often go unnoticed without training.
Professional vs. DIY Search Approaches
A professional patent searcher or patent attorney brings:
● Access to premium search tools
● Familiarity with obscure databases
● Legal insight to evaluate threats
Professionals can uncover indirect prior art—documents that describe your
invention in different wording or under a different context.
Hybrid approach: Begin with a DIY search to familiarize yourself with the
landscape. Then hire a professional for a conclusive report before filing.
Common Mistakes to Avoid During a Novelty Search
1. Searching too narrowly: Focusing only on your industry or keywords
may miss relevant inventions.
2. Ignoring non-patent literature: Journals, user manuals, and product
documentation can qualify as prior art.
3. Relying only on Google Patents: It lacks full global coverage and can
miss technical disclosures.
4. Assuming unique wording equals novelty: Many inventions are
phrased differently but function identically.
5. Not verifying foreign-language documents: Prior art can exist in any
language and still block your patent.
Even one overlooked article can lead to a patent rejection. Thoroughness
and expertise are key.
Additional Considerations
Patent Office Examiner Searches Are Not Enough
Some inventors assume the USPTO will conduct their own search after the
application is filed. While true, this search occurs only after you’ve paid the
fees. And if prior art is found, your application may be rejected without
refund.
Doing your own search before filing puts you in control.
International Implications
Novelty is judged on a global scale. An article published in China or a
patent filed in Japan can prevent you from securing rights in the U.S., even
if you’ve never heard of it.
This is why global search coverage is essential, even for local businesses.
Patent-Pending ≠ Patent-Approved
Many products display “patent pending,” but not all of them will be granted.
A novelty search improves the likelihood that your application will convert
into an issued patent.
FAQs
Q: Can I skip a novelty search for a provisional patent?
A: Technically yes, but it’s risky. Provisional applications are the basis for
later filings. If prior art exists, the entire effort may be invalidated later.
Q: How long does a novelty search take?
A: DIY searches may take a few days. Professional searches typically
require 1–2 weeks, depending on complexity.
Q: Is a novelty search legally required?
A: No. But it's highly recommended to avoid wasting money on
unpatentable ideas.
