Patent Search
Before investing significant time and resources into developing your invention, it is essential to conduct a patent search. This process helps determine if your idea is novel and non-obvious by uncovering existing patents and publications (known as "prior art"). A good starting point is a preliminary search, which aims to find patents or applications that are identical or very similar to your core concept. After this initial review, a more comprehensive patentability search should be performed to find a wider range of prior art that could prevent your patent from being granted or limit the scope of your claims.
Select a search type from the drop down menu and either. Enter a patent or publication number to retrieve a patent document or enter a brief description of your invention below to perform an AI-based semantic search.

Patent Search FAQ
What is the Patent Search tool, and what can it do?
TCP Law's free Patent Search tool offers two search modes: enter a patent or publication number to retrieve a specific patent document, or enter a brief description of your invention to perform an AI-based semantic search. It is designed as an accessible starting point for inventors exploring the patent landscape before investing in development or filing. Use it alongside TCP Law's patent search services for a complete prior art assessment.
Why is conducting a patent search essential before developing or filing for my invention?
Before investing significant time and resources into developing your invention, a patent search helps determine whether your idea is novel and non-obvious by uncovering existing prior art. Discovering conflicts early — before significant investment — allows you to refine your concept or adjust your claims strategy. Discovering the same prior art after filing is far more costly. Book a free consultation to discuss your invention.
What is prior art, and why does it matter for my patent application?
Prior art refers to any existing patents, published applications, or other publicly available materials disclosing elements similar or identical to your invention. It is the primary basis on which the USPTO evaluates novelty and non-obviousness. A single reference disclosing every element of your invention can prevent grant. Understanding prior art before filing allows the application to be drafted to distinguish your invention. Use the free Patent Search tool as a first step.
What is the difference between a preliminary and a comprehensive patent search?
A preliminary search finds patents identical or very similar to your core concept — a fast initial read on obvious conflicts. A comprehensive patentability search covers a wider range of prior art that could prevent grant or limit claim scope — including secondary references that may be combined to form an obviousness rejection. Use the Patent Search tool for preliminary screening, then contact TCP Law for a comprehensive professional search.
How does the AI-based semantic search mode work?
The semantic search mode analyzes the substance of your invention description — its functional and structural characteristics — rather than relying on exact keyword matches. This surfaces relevant prior art even when different terminology is used to describe similar technology. Traditional keyword searches miss this. Enter a brief plain-language description of your invention in the Patent Search tool and review results before your patent consultation with TCP Law.
Can I use the tool to look up a specific patent I've heard about?
Yes — one of the two search modes allows you to enter a patent or publication number directly to retrieve the corresponding document. This is useful for researching a competitor's patent, evaluating a patent asserted against you in a cease and desist letter, or reviewing a specific reference cited in a prior art search. View patent samples to familiarize yourself with patent document structure before searching. Contact TCP Law to interpret results professionally.
Does using the Patent Search tool protect my invention or establish any legal rights?
No — the tool's disclaimer is explicit. It is for informational purposes only, does not constitute legal advice, and does not create an attorney-client relationship. Using the tool does not file a patent application, establish a priority date, or create any legal rights. Only a properly filed provisional or non-provisional patent application establishes priority. Book a free consultation to take the next step toward protecting your invention.
What should I do after running a patent search with the tool?
After reviewing results, consult a patent attorney who can interpret findings in the context of your invention and filing goals. A clean result means no obvious conflict was surfaced — not that your invention is definitely patentable. Closely related results provide strategic drafting information. In either case, a professional patent search and attorney consultation are the appropriate next steps. Contact TCP Law to discuss your results.
How can patent search results strengthen my application before filing?
Search results inform strategic application drafting. By understanding how your invention compares to identified prior art, the application can include additional technical features, alternative embodiments, and claim limitations that distinguish your invention from known technology. Results also help anticipate USPTO rejection types before they arise. Use the Patent Search tool as a starting point, then contact TCP Law for professional search and drafting services.
Is it a myth that searching only U.S. patents is sufficient prior art due diligence?
Yes — prior art includes any public disclosure worldwide: foreign patents, PCT publications, academic papers, conference proceedings, and product documentation. A U.S.-only search leaves a significant gap. TCP Law's AI platform supports semantic searches that surface relevant prior art across broader sources — beyond what keyword-only tools find. Use the free Patent Search tool as a first step, then book a consultation for a complete professional assessment.
