How much does a patent search cost? $500 vs $3,000, what is the difference?
Updated June 2026
The short answer
Patent searches are commonly advertised from about $100 to $500 for automated or quick knockout searches, and from roughly $1,000 to $3,000 and up for a professional patentability search with an analyst-written report. Both are real products; they answer different questions with different levels of confidence.
A $500 search tells you whether an obvious blocker exists. A $3,000 search tells you what the prior art landscape around your invention actually looks like, which is the information a filing decision and a claims strategy are built on.
What the two price classes typically include
| $100 to $500 search | $1,000 to $3,000+ search |
|---|---|
| Keyword queries in one or two databases | Classification-based strategy (CPC) plus keywords across global full-text databases |
| Automated, or light human review | Professional searcher, often with domain expertise |
| Granted patents, usually US-centric | Patents, published applications, and non-patent literature across jurisdictions |
| A hit list, little or no analysis | A written report mapping the closest art to your invention's features |
| Good for early triage and obvious knockouts | Good for filing decisions, claim strategy, and investor diligence |
What the cheap search is, and when it is enough
At the low end you are buying keyword queries against one or two patent databases, usually US-centric, run by software or with light human review. The output is a hit list. That is legitimately useful for early triage: it kills obviously unoriginal ideas for a few hundred dollars before any real money gets spent, and for an independent inventor testing a hunch, that is fair value.
The limits are structural. Keyword searches miss patents that describe the same invention in different vocabulary, which happens constantly because patent drafters deliberately vary terminology. Non-patent literature, the academic papers and product documentation that also count as prior art, is usually absent. And a hit list without analysis leaves you to judge what the hits mean.
What the professional search adds
In addition to keywords, a trained searcher builds a classification-based strategy using CPC patent classification codes, which group technology by function rather than vocabulary, so the search finds inventions however they were worded. The search runs across full-text databases covering multiple jurisdictions, includes published applications and non-patent literature, and follows citation trails outward from the closest hits. The deliverable is a written report mapping the closest references to the specific features of your invention.
The report is the actual product. It gives your patent attorney the basis for drafting claims that steer around the art instead of into it, and it gives you a grounded read on whether filing is worth the money at all.
Matching the search to the money at stake
The practical test is what the search protects. If the next step is an attorney-drafted application that will commonly cost five figures over its life in legal and government fees, a few thousand dollars of search is cheap insurance against drafting claims the examiner will shred or filing on something unpatentable. If the next step is deciding whether an idea deserves any further attention, the cheap search is proportionate.
Searches that answer harder questions cost more again. Freedom-to-operate and invalidity searches work at the claims level with legal exposure attached, and their published ranges run well past patentability work. ipCG scopes search projects fixed-price after a free discovery call; searches frequently run inside larger landscape or disclosure programs where the marginal cost drops.
Related questions
Can I do a free patent search myself?
Yes, and you should before paying anyone. Google Patents, Espacenet, and the USPTO's full-text search are free and good for orientation, and Google Patents even supports CPC classification searching while Google Scholar covers non-patent literature. Paid searches earn their fee based on experience in crafting comprehensive search strings and finding cleverly hidden patents that may be relevant to your invention.
Does a clean search report guarantee my patent will issue?
No. No search is exhaustive, examiners run their own searches, and applications that were unpublished at search time can surface later. A good search reduces surprise dramatically; nothing eliminates it.
Why do freedom-to-operate and invalidity searches cost more?
They answer a different and harder question. Patentability compares your invention to all prior art; FTO and invalidity work analyze specific in-force claims with legal consequences attached, so the review is deeper and the stakes price in.
What does ipCG charge for a search?
We do not publish a flat search price because scope varies too much to make one honest. Search work is quoted fixed-price after a free discovery call, and often runs as part of a disclosure or landscape engagement.
Search before you spend
A right-sized search is the cheapest decision insurance in the patent process. Tell us what the search needs to support and we will scope it fixed-price. The discovery call is free.
